Two aircraft carry the designation X-44A, both of them Lockheed Martin, and only one of them was ever built. The famous one is the Multi-Axis No-Tail Aircraft, a proposed derivative of the F-22 with every tail surface deleted and every axis of control handed to the exhaust, which was approved in 1999, funded briefly and cancelled without metal being cut [Lockheed Martin X-44 MANTA]. The other was a tailless unmanned flying wing of about nine metres span, built by the Skunk Works in 1999, first flown in 2001, and kept out of public view until March 2018 [Skunk Works reveals the missing link in a secret unmanned history] [Lockheed Skunk Works X-44A flying-wing drone revealed]. The aeroplane that exists is the one nobody had heard of, and a museum now holds it [Lockheed Martin X-44A, National Museum of the United States Air Force]. This is the forty-fifth article in the X-Planes series, following the X-1, the X-2, the X-3, the X-4, the X-5, the X-6, the X-7, the X-8, the X-9, the X-10, the X-11, the X-12, the X-13, the X-14, the X-15, the X-16, the X-17, the X-18, the X-19, the X-20, the X-21, the X-22, the X-23, the X-24, the X-25, the X-26, the X-27, the X-28, the X-29, the X-30, the X-31, the X-32, the X-33, the X-34, the X-35, the X-36, the X-37, the X-38, the X-39, the X-40, the X-41, the X-42, and the X-43.

A vehicle existed and produced data, and almost none of that data has been released. No specification for the X-44A has been published beyond a span, an engine, two dates and three performance figures, and the MANTA never reached the point of having specifications to publish, so the statement of what is unknown carries the weight a specification table would otherwise carry.

The finding is that the question the MANTA existed to answer had already been answered in flight, five years earlier, by an aeroplane this series has already covered. The X-31 flew a hundred percent simulated vertical tail removal at Mach 1.2 and 37,500 feet in March 1994, restabilised by yaw thrust vectoring, and its report concludes that tailless and reduced-tail fighters are feasible [Bosworth and Stoliker 1996] [Huber and Schellenger 1994]. The interesting question is therefore not whether the MANTA would have worked but what its demonstration point was worth, and arithmetic can settle that. The demonstration was flown at a point whose authority ratio stands within fourteen percent of the worst in the entire supersonic envelope, so it very nearly covered everything above the speed of sound. What it did not cover is the landing, and the reason is the throttle rather than the aerodynamics.

The Research Question

The binding unknown was whether an aeroplane can be held straight by its engines when it has nothing else to be held straight by.

A vertical tail exists to supply two different things that are easy to confuse. It supplies static directional stability, meaning a restoring moment that grows with sideslip and points the nose back into the wind, and it supplies control power, meaning a moment the pilot can command at will. The stability condition is a sign condition on one derivative. It is written out because the article concerns what happens when it fails. The requirement that it be satisfied at all is older than the jet age, having been set out in the report that first turned pilot opinion into numbers [Gilruth 1943].

\[N = q S b \, C_{n\beta} \, \beta \qquad \text{stable} \iff C_{n\beta} > 0\]

Deleting the tail removes both, and the two are replaced by different mechanisms. Stability is replaced by feedback, which is a matter of sensors, computation and actuator bandwidth. Control power is replaced by thrust deflection, which is a matter of how much momentum flows through the nozzle and how far that nozzle sits behind the centre of gravity. The distinction between the two is standard and is made in every treatment of the subject [Etkin and Reid, Dynamics of flight] [Nelson, Flight stability and automatic control] [Perkins and Hage, Airplane performance, stability and control], and the conventional way of sizing the surface that supplies both is a tail volume coefficient,

\[V_{v} = \frac{S_{v} \, l_{v}}{S \, b}\]

which is a ratio of areas and arms carrying no propulsion term at all [Raymer, Aircraft design, a conceptual approach] [Torenbeek, Synthesis of subsonic airplane design]. The authority that coefficient buys follows from it directly, with $a_{v}$ the fin’s lift-curve slope, $\tau$ the rudder effectiveness and $\eta_{v}$ the dynamic pressure ratio at the tail.

\[C_{n \delta_{r}} = - V_{v} \, a_{v} \, \tau \, \eta_{v}\]

The methods for putting numbers into that expression are themselves primary literature [Campbell and McKinney 1951] [Toll and Queijo 1948] [Jones and Alksne 1951], and the swept-wing and supersonic cases needed separate treatments because the subsonic charts do not carry over.

Every term in that expression is geometry or aerodynamics and none of it is thrust, so a rudder’s authority is a coefficient that barely moves with Mach number and whose moment therefore grows as the dynamic pressure. That asymmetry carries the argument, and the form of the equation shows it before any number is put into it. For a fighter tail volume near 0.07, a lift-curve slope near 2.5 per radian, an effectiveness near 0.5 and a dynamic pressure ratio near 0.9, thirty degrees of rudder is worth a yawing moment coefficient of 0.0412.

A thrust-vectored aeroplane has no tail volume, so none of that apparatus applies to it, so the comparison below is built from first principles, without a design handbook.

The reason to delete it is not aerodynamic elegance. A vertical tail is the single largest contributor to the radar cross section of an otherwise carefully shaped aeroplane, because a flat surface standing perpendicular to the wing is a corner reflector for every illumination in the horizontal plane, and the shaping literature has said so for as long as it has existed [Knott, Shaeffer and Tuley, Radar cross section]. A flat plate of area $A$ returns

\[\sigma_{\text{plate}} = \frac{4 \pi A^{2}}{\lambda^{2}}\]

at normal incidence, and a dihedral formed by two such plates meeting at a right angle returns

\[\sigma_{\text{dihedral}} = \frac{8 \pi a^{2} b^{2}}{\lambda^{2}}\]

over a wide range of aspect angles rather than at one. The second relation is why a fin is expensive and the first is not the whole story. A flat plate is a large return in one direction and a corner is a large return in many, and the persistence across angle, unlike the peak, is what a designer cannot shape away. It also carries a trim drag penalty, a weight penalty, an actuation penalty and, on a supersonic aeroplane, a wave drag penalty. The MANTA’s own advertised benefits were reduced mechanical complexity, greater internal fuel volume and greater agility [Lockheed Martin X-44 MANTA] [X-44 MANTA Multi-Axis No-Tail Aircraft, GlobalSecurity], four different disciplines each wanting the same part removed.

The question this article asks is narrower and answerable. Given that the X-31 demonstrated tailless control at one flight condition, what fraction of a fighter’s envelope does one demonstrated point cover? That question has a closed-form answer that needs no wing area, no yaw derivative and no moment arm, and the analysis below is built around it.

For the unmanned aircraft the question is different, because the vehicle is subsonic and has no vertical tail to argue about. There the binding unknown was whether a small tailless flying wing could be designed, built and flown quickly enough to matter, and the article treats that as a manufacturing and configuration question, because its programme described it that way [Lockheed Skunk Works X-44A flying-wing drone revealed] [Lockheed Martin X-44A, National Museum of the United States Air Force].

Programme Origin

The MANTA, and the Aircraft It Was to Be Made From

The MANTA was a conversion proposal and not a clean-sheet aeroplane. The design took the F-22’s fuselage and engines, replaced the wing with a stretched delta, and deleted the vertical and horizontal tails entirely, leaving attitude control to three-axis thrust vectoring [Lockheed Martin X-44 MANTA] [Lockheed Martin X-44 MANTA tailless technology demonstrator proposal]. Preliminary work was under way by May 1999. The National Aeronautics and Space Administration approved the programme to start in June 1999 and the designation recorded at that point is X-44A. Funding ended in 2000 [Lockheed Martin X-44 MANTA].

The sources date the end only approximately, and the article does not make them more precise. The encyclopaedia entry says funding ended in 2000 [Lockheed Martin X-44 MANTA]. Two other accounts place the end around that year, one saying that the project seems to have died off about 2000 [Lockheed Martin X-44 MANTA tailless technology demonstrator proposal] and the other that it was supposedly cancelled around the turn of the millennium [Lockheed Skunk Works X-44A flying-wing drone revealed]. The 2003 NASA inventory of X-vehicles still describes a feasibility study in progress and a first flight as unlikely before 2007 [Jenkins, Landis and Miller, American X-Vehicles, An Inventory X-1 to X-50, NASA SP-2003-4531, 2003]. None of them cites a programme document, so the year remains approximate.

Nothing was built [Lockheed Skunk Works X-44A flying-wing drone revealed]. There is no airframe, no wind tunnel entry on record under the name, no flight and no report. The MANTA is a set of drawings and a set of claims, and the claims are what can be tested.

The X-44A, and the Programme That Had Gone Quiet

The unmanned X-44A fills a hole in a public record that had been visibly empty. Lockheed’s high-altitude unmanned reconnaissance line ran from the RQ-3 DarkStar, which first flew on 29 March 1996 and was terminated by the Department of Defense in January 1999 [Lockheed Martin RQ-3 DarkStar], to the P-175 Polecat, which first flew in 2005 [Lockheed Martin P-175 Polecat], to the RQ-170 Sentinel [Lockheed Martin RQ-170 Sentinel]. Between January 1999 and 2005 the public record showed nothing at all [Skunk Works reveals the tailless X-44A]. The gap reflects how the organisation works and was no accident, since the Skunk Works was built to run programmes that do not announce themselves [Rich and Janos, Skunk Works]. The X-44A occupies that gap, having been built in 1999, the year DarkStar was cancelled, and flown in 2001 [Skunk Works reveals the missing link in a secret unmanned history] [Lockheed Skunk Works X-44A flying-wing drone revealed].

Its stated purposes were manufacturing and configuration, not performance. The programme is described as proving rapid manufacturing techniques, demonstrating penetrating reconnaissance, and establishing the aerodynamic validity of a relatively small tailless swept flying wing [Lockheed Skunk Works X-44A flying-wing drone revealed]. That ordering matters, because a vehicle built to prove that it can be built quickly is dimensioned by its factory rather than by its mission, and the published endurance of an hour and a half and range of 230 miles are those of a short-range demonstrator [Lockheed Martin X-44A, National Museum of the United States Air Force].

It was revealed at the Los Angeles County Air Show in March 2018 and placed on public display in October 2020, in the Research and Development gallery of the National Museum of the United States Air Force [Lockheed Martin X-44A, National Museum of the United States Air Force] [Exclusive photos, the X-44A breaks cover]. Seventeen years elapsed between the first flight and the first photograph.

The Designation and Its Two Referents

Several neighbouring numbers turn on a designation that may not belong to the vehicle it is attached to, and the X-44 is the sharpest case, because both claimants are Lockheed Martin products, both were current in 1999, and both are recorded as X-44A.

The X-39 was reserved and never assigned to anything, the X-41 carried a designation allocated years before the programme it is now attached to existed, and the X-42 had two sources describing different vehicles four years apart.

Three things about the record need stating precisely.

First, the reference literature has split into two entries instead of reconciling them. The general encyclopaedia carries a page for the MANTA and a separate page for the unmanned vehicle, and the second page states that it is apparently unrelated to the first [Lockheed Martin X-44 MANTA] [Lockheed Martin X-44, the unmanned vehicle]. A disambiguation page exists to route between them [X44, the disambiguation page]. Splitting is the correct editorial response to a genuine collision, but it does not resolve one.

Second, the specialist designation registry does not carry the number at all. Andreas Parsch’s Appendix 4 to the Directory of U.S. Military Rockets and Missiles covers undesignated and unusual unmanned vehicles and holds pages for the X-41, the X-42, the X-45, the X-47 and the X-48 [Parsch, Directory of U.S. Military Rockets and Missiles, Appendix 4]. A request for an X-44 page returns a not-found response listing those five and the X-64 as near misses. The registry that documents this series’ other disputed numbers most carefully is silent on this one. This article reports that silence as an absence, which falls short of a denial.

Third, the journalism that broke the story said openly that it did not know. The account that first reported the aircraft states that it is unclear how the flying wing came to carry the same designation as the manned proposal and that there appears to be no direct relation between the two programmes [Lockheed Skunk Works X-44A flying-wing drone revealed]. A reporter who has the aeroplane and the photographs and still cannot explain the number is evidence about the number, not about the reporting.

The designation system has a documented allocation process. Aircraft designations are governed by Department of the Air Force Instruction 16-401, which covers the naming of aerospace vehicles and the bureaucratic steps by which a designation is assigned [Parsch, Current Designations of U.S. Military Aircraft]. A number issued twice is therefore either a failure of that process or evidence that one of the two allocations was never made through it. The public record does not say which, and this article does not guess.

One structural observation survives without resolving anything, and arithmetic establishes it. The X-planes numbering is a finite resource issued consecutively and never replenished, the mechanism on which the X-39 article builds its permanence argument. Writing $N$ for the highest number issued, $r$ for those reserved and never used and $c$ for those issued more than once, the vehicles the sequence can name is

\[V = N - r + c\]

while the numbers consumed is $N$ alone. A collision is the only term in that expression that adds a vehicle without consuming a number, so it is the one anomaly class that costs the register nothing and the reader everything. The register’s accounting cannot see it, because $N$ is what the register stores and $c$ is not.

Sizing From First Principles

The MANTA’s claim is testable without knowing anything about the MANTA. What follows derives the quantity that decides whether propulsive yaw control is sufficient, shows that two of the three variables it appears to depend on cancel identically, and then locates the flight condition that binds.

The Quantity That Has to Be Compared

A tailless aeroplane needs a yawing moment and has one available. The question is the ratio.

Let $q$ be the dynamic pressure, $S$ the wing reference area, $b$ the span, $C_{n\beta}$ the directional stability derivative and $\beta$ the sideslip angle. The aerodynamic yawing moment that must be produced, whether to trim a disturbance or to restrain a divergence, is

\[N_{\text{req}} = q S b \left| C_{n\beta} \right| \beta\]

Let $F_{g}$ be the gross thrust passing through the nozzles, $\ell$ the distance from the centre of gravity to the nozzle exit and $\delta$ the yaw deflection angle of the jet. The moment available is

\[N_{\text{av}} = F_{g} \ell \sin \delta\]

The argument turns on the ratio of these two.

\[\mathcal{R} \equiv \frac{N_{\text{av}}}{N_{\text{req}}} = \frac{F_{g} \ell \sin \delta}{q S b \left| C_{n\beta} \right| \beta}\]

The available moment can be put in the same currency as the rudder, and doing so is the cleanest way to see what the exchange costs. Dividing the vectored moment by $q S b$ gives a propulsive tail volume, a dimensionless number directly comparable with the $C_{n \delta_{r}}$ above.

\[V_{p} \equiv \frac{F_{g} \, \ell \, \sin \delta_{\max}}{q \, S \, b}\]

The article’s central finding is that this quantity does not behave like a rudder’s. A rudder’s coefficient is fixed by geometry. This one carries the thrust in its numerator and the dynamic pressure in its denominator, so it falls as the aeroplane goes faster and collapses when the throttle closes.

Inverting the ratio for the quantity a control system commands gives the required deflection.

\[\sin \delta = \frac{q \, S \, b \, \left| C_{n\beta} \right| \beta}{F_{g} \, \ell}\]

Dynamic pressure is not independent of static pressure, and writing it in those terms is the step the rest of the derivation needs. With $\gamma$ the ratio of specific heats, $p$ the ambient static pressure and $M$ the Mach number,

\[q = \tfrac{1}{2} \rho V^{2} = \tfrac{1}{2} \rho M^{2} \gamma R T = \tfrac{1}{2} \gamma p M^{2} = 0.7 \, p M^{2}\]

The moment form above is the standard linearised one [Yechout and Morris, Introduction to aircraft flight mechanics] [Schmidt, Modern flight dynamics] [Roskam, Airplane flight dynamics and automatic flight controls], and the substitution for dynamic pressure follows from the definition of Mach number and the perfect gas law together [Anderson, Fundamentals of aerodynamics] [McCormick, Aerodynamics, aeronautics and flight mechanics]. The substitution is an exact identity. Evaluating both forms at every flight condition in the analysis gives the same dynamic pressure to within one part in a million.

The Engine Puts the Static Pressure Back In

Gross thrust varies, and the way it varies produces the result. A fixed-geometry engine running at its maximum corrected rotational speed passes a constant corrected mass flow, so the physical mass flow follows the total conditions at the compressor face. With $\delta_{2}$ and $\theta_{2}$ the total pressure and total temperature at that station referred to sea level static conditions,

\[\dot{m} = \dot{m}_{\text{ref}} \frac{\delta_{2}}{\sqrt{\theta_{2}}}\]

This corrected-parameter machinery is general to engine performance [Mattingly, Elements of gas turbine propulsion] [Cumpsty, Jet propulsion]. It is used here for one property, the variation of physical mass flow with ambient conditions.

The total conditions follow from the ambient conditions and the flight Mach number through the isentropic relations, reduced by the inlet total pressure recovery $\eta_{r}$,

\[\delta_{2} = \frac{p}{p_{\text{SL}}} \left( 1 + \tfrac{\gamma - 1}{2} M^{2} \right)^{\frac{\gamma}{\gamma - 1}} \eta_{r} \qquad \theta_{2} = \frac{T}{T_{\text{SL}}} \left( 1 + \tfrac{\gamma - 1}{2} M^{2} \right)\]

which for $\gamma = 1.4$ gives, after cancelling one half power of the ram term,

\[\dot{m} \propto \frac{p}{p_{\text{SL}}} \, \eta_{r} \, \frac{\left( 1 + 0.2 M^{2} \right)^{3}}{\sqrt{T / T_{\text{SL}}}}\]

Gross thrust is that mass flow times a jet velocity, and the jet velocity varies too. For a nozzle expanding from a total temperature $T_{t7}$ fixed by the afterburner limit,

\[V_{j} = \sqrt{2 \, c_{p} \, T_{t7} \left[ 1 - \left( \frac{p}{p_{t7}} \right)^{\frac{\gamma - 1}{\gamma}} \right]}\]

Everything on the right is fixed by the engine except the nozzle pressure ratio, which rises with flight Mach number through the same ram term the mass flow carries. The derivation first treats $V_{j}$ as constant, which is the simpler and, as shown under Where the Framing Breaks Down, the more pessimistic choice, and then relaxes it and reports how much the answer moves.

\[F_{g} = \dot{m} V_{j} + \left( p_{e} - p \right) A_{e} \approx \dot{m} V_{j}\]

The Static Pressure Cancels Exactly

Assembling the ratio, the ambient static pressure appears once in the numerator and once in the denominator, to the same power.

\[\mathcal{R} \propto \frac{ \dfrac{p}{p_{\text{SL}}} \eta_{r} \dfrac{(1 + 0.2 M^{2})^{3}}{\sqrt{T/T_{\text{SL}}}} }{ 0.7 \, p M^{2} } = \frac{ \eta_{r} \left( 1 + 0.2 M^{2} \right)^{3} }{ 0.7 \, p_{\text{SL}} \, M^{2} \sqrt{T/T_{\text{SL}}} }\]

The pressure is gone, so the ratio does not depend on altitude except through temperature. Above the tropopause the standard atmosphere holds temperature constant at 216.65 kelvin, so in that region the ratio is a function of Mach number alone.

\[\mathcal{R}(M) \propto \frac{\eta_{r}(M) \left( 1 + 0.2 M^{2} \right)^{3}}{M^{2}} \qquad h > 11 \ \text{km}\]

The cancellation can also be confirmed numerically. Evaluated through the full standard atmosphere at Mach 1.2, the ratio takes the same value at five altitudes from 11,000 metres to 65,000 feet to within one part in ten to the twelfth, and the closed form above reproduces the atmosphere-driven value exactly at three further altitudes. The cancellation is a structural property of the ratio, independent of numerical coincidence.

Below the tropopause the cancellation is only partial, because temperature varies there. The residue is the remaining temperature term, which needs no empirical curve because the standard atmosphere supplies it in closed form,

\[T(h) = T_{\text{SL}} - L h \quad (h \le 11 \ \text{km}) \qquad T(h) = 216.65 \ \text{K} \quad (h > 11 \ \text{km})\]

so the ratio at altitude $h$ relative to the isothermal region is

\[\frac{\mathcal{R}(h)}{\mathcal{R}(h > 11 \ \text{km})} = \sqrt{\frac{T_{11}}{T(h)}}\]

The lapse rate, the tropopause altitude and the isothermal temperature above it are the standard values [U.S. Standard Atmosphere 1976], and every altitude quoted is a pressure altitude in that model rather than a geometric one.

Each entry in the table below is that square root, so the table needs no vehicle and no engine. The residue is not negligible and it runs the unhelpful way.

altitude ratio relative to 11 km, same Mach
sea level 0.8671
10,000 ft 0.8985
20,000 ft 0.9337
30,000 ft 0.9733
11 km and above 1.0000

A tailless aeroplane is thirteen percent worse off at sea level than at altitude at the same Mach number, and the entire effect is the temperature term $\sqrt{T/T_{\text{SL}}}$, which enters because a colder engine face passes more mass.

Where the Ratio Has Its Minimum

Intuition says the hardest case for a thrust-vectored aeroplane is the fastest one, because dynamic pressure grows as the square of Mach number. Intuition is wrong, because ram compression grows faster.

Taking ideal recovery for a moment, the Mach dependence is

\[f(M) = \frac{\left( 1 + 0.2 M^{2} \right)^{3}}{M^{2}}\]

Differentiating with respect to $u = M^{2}$,

\[\frac{d}{du} \left[ \frac{(1 + 0.2u)^{3}}{u} \right] = \frac{(1 + 0.2u)^{2} \left( 0.4 u - 1 \right)}{u^{2}}\]

which vanishes at $u = 2.5$, so the worst Mach number is exactly $\sqrt{5/2}$.

\[M^{\ast} = \sqrt{2.5} = 1.5811 \qquad f(M^{\ast}) = \frac{1.5^{3}}{2.5} = \frac{3.375}{2.5} = 1.35\]

Both the location and the value are exact, and both can be recovered without the algebra. Bisection on a numerically differenced derivative finds the same minimising Mach number to six decimal places, and the function evaluated there equals 1.35 to machine precision.

Adding a realistic inlet total pressure recovery moves the minimum and does not remove it. The standard correlation, the military specification recovery that NASA’s Glenn Research Center gives as a good first estimate above Mach one while noting that actual inlets usually recover somewhat less [NASA Glenn Research Center, Inlet performance], is

\[\eta_{r}(M) = \begin{cases} 1 & M \le 1 \\ 1 - 0.075 \, (M - 1)^{1.35} & M > 1 \end{cases}\]

and with it the stationarity condition is no longer solvable in closed form, because differentiating the product gives

\[\frac{\eta_{r}'(M)}{\eta_{r}(M)} + \frac{1.2 M}{1 + 0.2 M^{2}} - \frac{2}{M} = 0\]

which is transcendental and is solved by golden-section search. The ideal closed form remains the exact reference from which the corrected minimum is displaced.

Mach ideal recovery with recovery
0.3 7.900 7.968
0.5 3.121 3.148
0.7 1.821 1.836
0.9 1.305 1.317
1.0 1.165 1.175
1.2 1.000 1.000
1.4 0.927 0.915
1.5811 0.910 0.885
1.674 0.913 0.881
1.8 0.931 0.887
2.0 0.983 0.917
2.25 1.085 0.984

Every column is normalised to Mach 1.2, the condition the X-31 flew. With recovery included the minimum sits at Mach 1.674 and the demonstrated point stands 1.135 times above it.

That number is the answer to the question this article set. The X-31 demonstrated tailless control at a point that is thirteen and a half percent easier than the worst point in the supersonic envelope, and no point between Mach 1.2 and Mach 2.25 is more than twelve percent harder than what was flown. A single demonstrated supersonic point very nearly covered the supersonic envelope. That result is far stronger than the demonstration claimed, and it follows from a cancellation rather than from a simulation.

It also inverts the expectation. The demonstration was not flown at a soft condition chosen to flatter the concept. On this measure it was flown next to the hardest one available, and whether that was by design or by the accident of what the X-31’s envelope allowed, the public record does not say.

The Crosswind Identity

The comparison above holds the sideslip angle fixed, which is right for a manoeuvre and wrong for a wind. A crosswind, or a lateral gust, has a fixed speed rather than a fixed angle, and the angle it produces grows as the aeroplane slows. With $V_{c}$ the crosswind speed,

\[\beta = \arctan \frac{V_{c}}{V} \approx \frac{V_{c}}{V} = \frac{V_{c}}{M \sqrt{\gamma R T}}\]

Substituting into the required moment,

\[N_{\text{req}} \propto q \beta = 0.7 \, p M^{2} \cdot \frac{V_{c}}{M \sqrt{\gamma R T}} \propto \frac{p M}{\sqrt{T}}\]

and the available moment already carries the same pressure and the same square root of temperature.

\[N_{\text{av}} \propto \frac{p \, \eta_{r} \left( 1 + 0.2 M^{2} \right)^{3}}{\sqrt{T}}\]

Both cancel. The required vector angle for a crosswind of given speed depends on Mach number and on no other variable.

\[\frac{N_{\text{req}}}{N_{\text{av}}} \propto \frac{M}{\eta_{r}(M) \left( 1 + 0.2 M^{2} \right)^{3}}\]

No pressure, no temperature, no altitude, no density and no true airspeed. Evaluated at Mach 0.8 at five altitudes from sea level to 55,000 feet with the throttle held, the required angle agrees to better than four parts in ten thousand, the residue being the difference between the arctangent and its argument.

Differentiating gives a result cleaner than the last one.

\[\frac{d}{dM} \left[ M \left( 1 + 0.2 M^{2} \right)^{-3} \right] = \frac{1 - M^{2}}{\left( 1 + 0.2 M^{2} \right)^{4}}\]

The crosswind demand peaks at exactly Mach one, at every altitude, in every atmosphere, for every crosswind speed and for every aeroplane. Evaluating the ideal form there gives a maximum that is a pure number,

\[h(1) = \frac{1}{(1 + 0.2)^{3}} = \frac{1}{1.728} = 0.578704\]

The only approximation in the derivation is the small-angle step, and its error is bounded and third order,

\[\frac{\arctan x - x}{\arctan x} \approx - \frac{x^{2}}{3}\]

Its size and its variation are two different quantities and only the second one matters here. The error itself reaches 1.25 percent at the eleven degrees of sideslip a fifteen metre per second crosswind produces on approach, and falls to 0.06 percent at the 2.43 degrees the same crosswind produces at the demonstration point. But the cancellation shown above is a comparison between altitudes at one Mach number, and the approximation is very nearly the same at all of them, so what survives into that comparison is only how much the error moves. At Mach 0.8 it moves by 3.3 parts in ten thousand between sea level and the tropopause. That variation is all of the residue in the comparison across altitudes reported above, an artefact of the approximation with no physical content.

Mach crosswind demand, Mach one taken as unity
0.23 0.385
0.4 0.629
0.6 0.842
0.8 0.963
1.0 1.000
1.2 0.971
1.5 0.850
1.8 0.695
2.25 0.477

Read at equal throttle, that table shows the approach to be the easiest case in the envelope. At an approach Mach number of 0.227 the demand is 38.5 percent of the transonic peak. The design of every conventional aeroplane suggests the opposite, because a conventional fin’s authority falls with dynamic pressure while a nozzle’s does not.

The Throttle on Approach

The table above holds the throttle fixed, and on an approach the throttle is not fixed. It is nearly closed.

An aeroplane descending a three degree glide slope at a lift to drag ratio of six in the landing configuration needs a thrust of

\[\frac{T}{W} = \frac{1}{L/D} - \sin \gamma = \frac{1}{6} - \sin 3^{\circ} = 0.16667 - 0.05234 = 0.11433\]

which for a landing weight near twenty tonnes, close to the F-22’s empty weight of 19,700 kilograms [Lockheed Martin F-22 Raptor], against two engines rated at 35,000 pounds or 156 kilonewtons each [Pratt and Whitney F119], is about 7.2 percent of the maximum available thrust. The same engine source reports actual thrust of 164.6 to 173.5 kilonewtons, which would put that fraction between 6.5 and 6.8 percent, so the rated figure is the cautious choice. The control authority falls with it, because the control authority is the thrust.

Inverting for the throttle setting that restores the demonstrated margin gives the size of the problem. Writing $\Pi$ for the throttle fraction and requiring the ratio of demanded to available moment to match the demonstrated one,

\[\Pi = \frac{q_{\text{app}} \, \beta_{\text{app}}}{q_{\text{dem}} \, \beta_{\text{dem}}} \cdot \frac{\dot{m}(M_{\text{dem}}, h_{\text{dem}})}{\dot{m}(M_{\text{app}}, 0)}\]

in which the wing area, the span, the yaw derivative, the moment arm and the maximum deflection have all cancelled, because they appear identically in both conditions. Taking the X-31’s Mach 1.2 point at maximum thrust as the unit of adequacy, and requiring the same ratio on a sea-level approach at 150 knots in a 15 metre per second crosswind, the throttle must stand at

\[\text{throttle} = 0.384 \qquad \text{against } 0.072 \text{ needed to fly the glide slope}\]

a factor of 5.33. The landing-configuration ratio of six is an assumption. The approach and landing study flown with a straight-wing fighter at Edwards in 1959 measured a peak ratio of about four with gear and flaps extended at zero thrust [Matranga and Armstrong, Approach and landing investigation at lift-drag ratios of 2 to 4 utilizing a straight-wing fighter airplane], and at four the glide slope needs 12.4 percent of maximum thrust and the factor is 3.09. The aeroplane must carry three to five times the thrust its flight path needs, purely in order to have the yaw control its flight path does not need until something goes wrong.

That requirement is not merely expensive. It is impossible, and saying why is the strongest result in this article. An aeroplane in level flight at a given thrust has a lift to drag ratio fixed by that thrust and its weight, by the most elementary relation available.

\[T = D = \frac{W}{L/D} \qquad \Longrightarrow \qquad \frac{L}{D} = \frac{W}{\Pi \, T_{\max}}\]

At 38.4 percent of maximum thrust, the implied ratio is

landing weight implied lift to drag ratio at that thrust
20,000 kg 1.59
22,000 kg 1.75
24,000 kg 1.91

Those ratios are below anything flown in the low lift to drag landing research. The 1959 study reached an effective peak ratio of 2.7 with speed brakes, gear and flaps extended and the engine at idle, and its pilots judged that the tolerable limit had been reached [Matranga and Armstrong, Approach and landing investigation at lift-drag ratios of 2 to 4 utilizing a straight-wing fighter airplane]. To absorb the thrust that pure propulsive yaw control demands on approach, the aeroplane would have to be about two to nearly four times as draggy as a fighter in the landing configuration is, the range running from the measured ratio of four to the assumed ratio of six, and there is no drag device on a stealth aeroplane that can do that without undoing the reason the tails were removed in the first place.

The conclusion follows without any unpublished number, because every airframe quantity cancelled in the ratio. Pure thrust vectoring cannot meet a crosswind landing requirement, and a tailless fighter therefore needs an aerodynamic yaw effector that works at low speed even though it does not need one supersonically. The X-36 flew that architecture, with split ailerons and a thrust vectoring nozzle for directional control [McDonnell Douglas X-36], and the X-31 investigated it, with differential canard deflection studied as a yaw generator of the same order as its thrust vectoring vanes [Whiting 1996].

The MANTA proposed to delete every movable aerodynamic control surface [Jenkins, Landis and Miller, American X-Vehicles, An Inventory X-1 to X-50, NASA SP-2003-4531, 2003] [X-44 MANTA Multi-Axis No-Tail Aircraft, GlobalSecurity], although one account keeps control surfaces on the wing [Lockheed Martin X-44 MANTA tailless technology demonstrator proposal]. On this arithmetic, that claim does not survive contact with a crosswind.

The Engine-Out Case

The classic reason a twin-engine aeroplane has a large fin is the failure of one engine, and for a thrust-vectored aeroplane that case is almost free. The reason is an identity.

Let the live engine sit a lateral distance $y$ from the centreline with its nozzle a distance $\ell$ aft of the centre of gravity, and let it be deflected through an angle $\delta$. Its axial component produces a yawing moment about the centre of gravity of $F_{g} y \cos \delta$ toward the dead side, and its lateral component produces $F_{g} \ell \sin \delta$ the other way. Setting them equal,

\[F_{g} \ell \sin \delta = F_{g} y \cos \delta \qquad \Longrightarrow \qquad \tan \delta = \frac{y}{\ell}\]

The thrust cancels identically. The vector angle needed to trim an engine failure depends on nothing but where the engines are. It does not depend on how much thrust the live engine is making, on altitude, on speed, on the atmosphere or on any aerodynamic property of the aeroplane.

Two consequences follow from the same balance and neither needs a number. The axial thrust the aeroplane keeps while trimming is

\[F_{\text{axial}} = F_{g} \cos \delta = F_{g} \frac{\ell}{\sqrt{y^{2} + \ell^{2}}}\]

which at the angles in the table below costs under two percent, and the windmilling drag of the dead engine adds to the asymmetry it must cancel, so

\[\tan \delta = \frac{y \left( F_{g} + D_{\text{wm}} \right)}{\ell \, F_{g}}\]

Solving the moment balance numerically without cancelling the thrust by hand gives the same angle, at thrusts spanning three orders of magnitude from one kilonewton to one meganewton, agreeing with the arctangent to within one part in a billion.

lateral offset $y$ arm $\ell$ required $\delta$
0.70 m 6.5 m 6.15 deg
0.70 m 8.5 m 4.71 deg
0.85 m 7.5 m 6.47 deg
1.00 m 6.5 m 8.75 deg
1.00 m 7.5 m 7.59 deg
1.20 m 6.5 m 10.46 deg
1.20 m 8.5 m 8.04 deg

The published nozzle deflection of the F-22 is twenty degrees, and every angle in that table is below eleven [Pratt and Whitney F119]. Adding the windmilling drag of the dead engine at ten percent of the live engine’s gross thrust takes the middle case from 7.59 degrees to 8.34, still well within it.

A relation explains why a fin is large and a nozzle need not be, without appeal to intuition. Setting the fin’s yawing moment equal to the thrust asymmetry and solving for the geometry gives

\[S_{v} \, l_{v} = \frac{T \, y}{q \, a_{v} \, \tau \, \eta_{v} \, \delta_{r,\max}}\]

The dynamic pressure sits in the denominator, so the requirement blows up as the aeroplane slows. Halving the speed at which the failure must be survived quadruples the fin the aeroplane must carry for the rest of its life, and every one of the terms above except $q$ is a constant of the design. A fin must therefore be sized for the engine-out case at the lowest speed at which it can occur. A nozzle’s authority and the asymmetry it must cancel are the same quantity, so the case is speed-independent by construction. The engine-out requirement, one of the two classic fin-sizing cases, does not size a thrust-vectored aeroplane.

The other classic case is the crosswind landing, which the previous section showed cannot be met.

The Divergence and the Loop That Must Hold It

Control authority is necessary but not sufficient. An unstable aeroplane must also be stabilised faster than it diverges.

With the tail removed the directional mode diverges without oscillating, and its growth rate follows from the yawing moment of inertia $I_{z}$.

\[\lambda = \sqrt{\frac{q S b \left| C_{n\beta} \right|}{I_{z}}} \qquad t_{2} = \frac{\ln 2}{\lambda}\]

Neither the yaw derivative of a tailless F-22 nor its yawing inertia has been published, so the table brackets both across their plausible ranges and asserts no value.

$\left C_{n\beta}\right $ per radian $I_{z}$ kg m² $t_{2}$ approach $t_{2}$ Mach 1.2 at 37,500 ft
0.03 1.2 × 10⁵ 0.706 s 0.292 s    
0.03 2.0 × 10⁵ 0.911 s 0.377 s    
0.06 1.6 × 10⁵ 0.576 s 0.238 s    
0.10 1.2 × 10⁵ 0.386 s 0.160 s    
0.10 2.0 × 10⁵ 0.499 s 0.206 s    

Every cell in that table is under one second, and no supersonic cell reaches four tenths.

A time to double does not by itself place a requirement on the hardware. Turning it into a budget does, and a budget forces a conclusion an amplification cannot. Stabilising a real pole at $\lambda$ demands a loop crossover some multiple of it,

\[\omega_{c} = k \lambda \qquad k \approx 2 \ \text{to} \ 3\]

and a pure transport delay $\tau$ anywhere in that loop spends phase in direct proportion to the crossover it must survive,

\[\Delta \phi = \omega_{c} \tau \qquad \Longrightarrow \qquad \tau_{\max} = \frac{\Delta \phi}{k \lambda}\]

That delay has been measured in flight. Pure time delays were deliberately inserted into the control system of the F-8 digital fly-by-wire aeroplane and flown in low lift to drag landings [Berry et al 1980], and a later evaluation in pitch and roll found their effect strongly dependent on the task and severe in roll for landings in turbulence [Berry 1985]. The budget below therefore draws on flight data as well as on a phase argument.

Budgeting thirty degrees of phase margin to delay alone, and taking the middle of the inertia bracket, the total latency of sensing, computing and actuating must fit inside

condition $\lambda$ $\tau_{\max}$ at $k = 2$ $\tau_{\max}$ at $k = 3$
approach 1.203 /s 218 ms 145 ms
Mach 1.2 at 37,500 ft 2.909 /s 90 ms 60 ms

Sixty to ninety milliseconds is a demanding but ordinary digital flight control budget. The divergence is not beyond a person. Practised subjects holding a first-order divergence in a single-axis tracking task lost control at mean instabilities of 6.0 to 6.6 per second [Jex, McDonnell and Phatak, A critical tracking task for man-machine research related to the operator’s effective delay time], and the fastest divergence in the bracket above is 4.3 per second. What that comparison does not license is a pilot as the stabilisation loop of a fighter, because those subjects attended to nothing else and lost control with small stability margins at their limit, while the budget above reserves thirty degrees of phase. The stabilisation loop is therefore better given to machinery than to a person, a conclusion drawn from margin and attention as well as from speed. It also identifies which component binds, because sixty milliseconds is spent by an actuator far sooner than by a processor.

The X-31 report’s lessons emphasise sensors for this reason, as Sensing Sideslip below sets out. When the loop must close in a fraction of a second, the limiting component is the thing that measures sideslip, not the thing that produces the moment.

The X-44A From Its Published Performance

One dimension, one engine, two dates and three performance figures are the entire released specification. The span is about 30 feet, or 9.14 metres [Lockheed Skunk Works X-44A flying-wing drone revealed]. The engine is a Williams F112 of 732 pounds force, which is 3,256 newtons [Williams F112] [Williams International F112-WR-100 Turbofan, National Museum of the United States Air Force]. It was built in 1999 and flown in 2001 [Lockheed Skunk Works X-44A flying-wing drone revealed], and the museum gives a maximum speed of 176 miles per hour, an endurance of 1.5 hours and a range of 230 miles [Lockheed Martin X-44A, National Museum of the United States Air Force]. A trade account adds a wing sweep of about 30 degrees, a fixed tricycle landing gear, an all carbon fibre airframe and a long air data probe later removed, and describes the aircraft as built to investigate the stability and control of the configuration [Skunk Works reveals stealthy UAV demonstrator]. The engine is a cruise missile powerplant, developed for the AGM-129 Advanced Cruise Missile [AGM-129 Advanced Cruise Missile], a choice that brings small size and low cost along with a design point unlike an aeroplane’s.

The most useful comparison available is not to another unmanned aircraft. It is to the X-36, which used the same engine. The X-36 carried an F112 of the 700 pound force thrust class in an airframe of 10.4 feet or 3.17 metres span and 1,245 pounds or 565 kilograms takeoff gross weight, giving a thrust to weight ratio of 0.56 [Walker 1997]. The X-44A spans 2.88 times as much on the same thrust, which taking wing area as proportional to the square of span is a factor of

\[\left( \frac{9.144}{3.17} \right)^{2} = 8.32\]

more wing on the same engine. Two aircraft with one powerplant and an eight-fold difference in wing area are not variants of a concept. They are answers to different questions, and the wing records the difference.

Calibrating the thrust lapse on the DarkStar puts a number on the rest. The DarkStar published a service ceiling of 45,000 feet, a gross weight of 3,856 kilograms and a Williams FJ44-1A of 8.45 kilonewtons [Lockheed Martin RQ-3 DarkStar]. At the ceiling, thrust available equals drag at the best lift to drag ratio, so

\[T_{\text{SL}} \sigma^{n} = \frac{W}{(L/D)_{\max}} \qquad (L/D)_{\max} = \tfrac{1}{2} \sqrt{\frac{\pi e A\!R}{C_{D_{0}}}}\]

The second of those comes from a parabolic drag polar,

\[C_{D} = C_{D_{0}} + \frac{C_{L}^{2}}{\pi e A\!R} \qquad A\!R = \frac{b^{2}}{S}\]

maximised where the induced drag equals the zero-lift drag exactly, which fixes the lift coefficient the aeroplane must fly at,

\[C_{L}^{\ast} = \sqrt{C_{D_{0}} \, \pi e A\!R} \qquad \left( \frac{L}{D} \right)_{\max} = \frac{C_{L}^{\ast}}{2 \, C_{D_{0}}}\]

That polar and the best ratio it yields are the forms every preliminary design text gives [Raymer, Aircraft design, a conceptual approach] [Filippone, Advanced aircraft flight performance], and the thrust lapse exponent is the quantity that a design text would supply from a table and that the calibration below measures instead [Mattingly, Aircraft engine design].

The efficiency factor $e$ in the polar’s denominator carries the name of the report that introduced it as a way of collapsing a real aeroplane’s polar onto the elliptic one [Oswald 1932], and the value of 0.85 used here is a conventional one for a clean high aspect ratio wing rather than a measured property of this aircraft.

The middle relation also fixes the ceiling speed, which is therefore not free either.

\[V = \sqrt{\frac{2 W}{\rho \, S \, C_{L}^{\ast}}} \qquad \frac{W}{S} = \frac{\rho V^{2} C_{L}^{\ast}}{2}\]

Taking a 42 square metre wing, which gives an aspect ratio of 10.53, an Oswald efficiency of 0.85 and a zero-lift drag coefficient of 0.015, the lift coefficient at best ratio is 0.6494, the best ratio is 21.65 and the required thrust at the ceiling is 1,747 newtons. The density ratio there is 0.1936, so

\[n = \frac{\ln \left( 1747 / 8450 \right)}{\ln 0.1936} = 0.960\]

The calibration expresses the lapse in density ratio rather than in pressure ratio. The two differ by the temperature ratio, and at that altitude the density ratio is a third larger than the pressure ratio, so the choice of variable is not academic.

The museum’s figures fix the speed, so the unknown that remains is the altitude. The 230 miles covered in 1.5 hours is a mean speed of 153.3 miles per hour, or 68.55 metres per second, 87 percent of the 176 mile per hour maximum [Lockheed Martin X-44A, National Museum of the United States Air Force]. Range is distance over the ground, so if the range and the endurance describe the same flight the mean is a true airspeed in still air, and it argues against reading the maximum as an equivalent airspeed at altitude. At 45,000 feet an equivalent 176 miles per hour would be a true airspeed near 400, and an hour and a half at that speed would cover about 600 miles.

An aircraft cruising at or above its speed for best lift to drag ratio flies at a lift coefficient no greater than $C_{L}^{\ast}$, and for a jet with a parabolic polar the best-range speed lies above that speed. The ceiling speed relation above therefore becomes a bound, $W/S \le \rho V^{2} C_{L}^{\ast} / 2$, at whatever altitude the aircraft cruised, and on the DarkStar’s polar it depends on altitude alone. The last column compares the thrust the F112 makes at each altitude, lapsed with the exponent above, against the drag at the bound on the 7.94 square metre wing that the DarkStar’s aspect ratio gives a 30-foot span.

cruise altitude density ratio wing loading bound at 153 mph bound at 176 mph bound over the DarkStar’s thrust over drag
sea level 1.0000 191 kg/m² 251 kg/m² 2.08 4.7
10,000 ft 0.7385 141 kg/m² 185 kg/m² 1.53 4.8
20,000 ft 0.5328 102 kg/m² 134 kg/m² 1.11 4.9
30,000 ft 0.3741 71 kg/m² 94 kg/m² 0.78 4.9
40,000 ft 0.2462 47 kg/m² 62 kg/m² 0.51 5.0

The DarkStar’s wing loading on the same assumptions is 91.8 kilograms per square metre. The X-44A’s can exceed it only if the aircraft cruised below about 22,900 feet at its mean speed or 30,600 feet at its maximum, and even at sea level the bound is 2.08 times the DarkStar’s at the mean speed and 2.74 times at the maximum. A cruise at a reconnaissance ceiling is excluded. At best ratio on the same polar the F112 would hold assumed ceilings of 35,000 to 55,000 feet only at true airspeeds of 342 to 349 miles per hour, about twice the published maximum.

The wing loading therefore does not settle what the aeroplane was for, and the published endurance does. An hour and a half and 230 miles are the figures of a short-range demonstrator [Lockheed Martin X-44A, National Museum of the United States Air Force]. They agree with the purposes the programme stated [Lockheed Skunk Works X-44A flying-wing drone revealed] and with the stability and control investigation the trade account describes [Skunk Works reveals stealthy UAV demonstrator], and they are far from the loiter of the DarkStar, which was designed as a high-altitude endurance aircraft [Lockheed Martin RQ-3 DarkStar].

The last column carries a second finding. At every altitude the engine makes 4.7 to 5.0 times the clean-polar drag at the bound, so on that polar the aircraft could fly well above its published maximum. Either its drag is several times that of the assumed clean wing, which a fixed landing gear, an air data probe and a lower aspect ratio would each push towards, or the maximum is a limit set by something other than thrust, and the sources do not say which.

One caveat is load-bearing. The DarkStar’s wing area is not published in the sources used and 42 square metres is an assumption, and the X-44A’s aspect ratio is assumed equal to the DarkStar’s. The bound moves with the area through the aspect ratio, and the comparison moves further because the DarkStar’s loading varies inversely with the area. At assumed areas of 35 and 50 square metres the sea-level bound at the mean speed is 1.90 and 2.27 times the DarkStar’s, and the altitude above which the X-44A’s loading must be the lower of the two moves with it.

Dependent Systems

The Nozzle the F-22 Does Not Have

The most consequential fact about the MANTA is one that its published description obscures. The proposal is routinely described as converting an F-22 by deleting its tails and using its thrust vectoring nozzles for control [X-44 MANTA Multi-Axis No-Tail Aircraft, GlobalSecurity]. The F-22 has no yaw vectoring. Its Pratt and Whitney F119 engines carry two-dimensional convergent-divergent nozzles that deflect through plus or minus twenty degrees in pitch only [Lockheed Martin F-22 Raptor] [Pratt and Whitney F119].

A two-dimensional nozzle deflects in the plane of its flaps and in no other. The flaps rotate the jet through $\delta_{p}$ in one plane, and the components that reach the airframe are

\[F_{x} = F_{g} \cos \delta_{p} \qquad F_{z} = F_{g} \sin \delta_{p} \qquad F_{y} = 0\]

The zero side force is the problem. Producing yaw from the same nozzle requires the sidewalls to become deflecting surfaces, giving a second independent angle and a side force that did not previously exist,

\[F_{y} = F_{g} \cos \delta_{p} \sin \delta_{y} \qquad F_{x} = F_{g} \cos \delta_{p} \cos \delta_{y}\]

The product form is why the cross-coupling question had to be measured instead of assumed, and yaw vectoring calls for new hardware in the same envelope, which no new schedule for the existing hardware could supply. The MANTA is therefore not a subtraction from the F-22. It is a subtraction and an addition, and the addition is the harder half.

That addition has been measured, and the measurement is encouraging. Capone and Bare tested an advanced twin-engine supersonic-cruise fighter model with a two-dimensional convergent-divergent nozzle designed to give yaw vector angles of zero, ten and twenty degrees through yaw flaps in the nozzle sidewalls, with roll obtained from differential pitch vectoring, across Mach 0.20 to 2.47 [Capone and Bare 1987]. Their central result is that the force and moment increments produced by vectoring remain essentially constant over the whole angle of attack range at every Mach number tested, and that pitch and yaw vectoring show very little cross-coupling. A control effector whose authority does not vary with angle of attack is precisely what a tailless aeroplane needs, because an aerodynamic fin’s authority collapses at the angles where a fighter most wants it.

The wider measurement literature reports the same across several configurations [Capone and Mason 1986] [Berrier 1988], and the flight literature adds that vectoring hardware survives being flown [Anna and Kidman 1994].

The Wing

The MANTA’s wing is described only as a stretched delta of greater area than the F-22’s, carrying more internal fuel [Lockheed Martin X-44 MANTA]. No area, sweep, aerofoil or aspect ratio is public, so nothing can be dimensioned from it. What can be stated is the gain and the cost of the change.

A larger delta gains fuel volume, and volume grows faster than area, because a wing scaled in plan at fixed thickness ratio and aspect ratio gains depth as well as span.

\[\text{Vol} \propto \left( \frac{t}{c} \right) \frac{S^{3/2}}{\sqrt{A\!R}} \qquad \Longrightarrow \qquad \frac{\text{Vol}_{2}}{\text{Vol}_{1}} = \left( \frac{S_{2}}{S_{1}} \right)^{3/2}\]

A quarter more wing is forty percent more fuel, a better return than the linear reading of the claim suggests. It also brings a lower wing loading at fixed weight, and through it sustained turn rate at altitude,

\[n = \frac{q \, C_{L}}{W/S} \qquad \dot{\psi} = \frac{g \sqrt{n^{2} - 1}}{V}\]

It costs wave drag and it costs directional stability, and the second of those has a form that needs displaying because the article later has to assume a value for it. A slender body in sideslip carries the Munk moment, which is destabilising and depends on volume rather than on area,

\[C_{n\beta, \text{fus}} = - \frac{2 \left( k_{2} - k_{1} \right) \text{Vol}_{\text{fus}}}{S \, b}\]

That relation is a hundred years old and was derived for airships. Munk obtained the moment on a slender body in a stream in 1924, and the apparent-mass factor in the numerator is his [Munk 1924]. Multhopp adapted it to the aeroplane fuselage [Multhopp 1942], and Allen and Perkins added the viscous cross-flow term that the inviscid theory omits and that matters at the angles a fighter reaches [Allen and Perkins 1951]. The article uses the inviscid form, which is the conservative one for its purpose, since the cross-flow contribution grows with angle of attack and would make the aeroplane less stable still.

Inverting that relation is the only check available on the assumed instability bracket, since neither the derivative nor the volume is published. At an apparent-mass factor of 0.94, a derivative of 0.06 per radian implies a fuselage volume of 33.8 cubic metres, which over the F-22’s 18.92 metre length [Lockheed Martin F-22 Raptor] is a mean cross-section of 1.79 square metres. No fuselage volume is published, so this check cannot say whether the bracket is conservative. The two F119 engine envelopes alone, 497.8 centimetres long and 121.9 centimetres in overall diameter [Pratt and Whitney F119], enclose 11.6 cubic metres, about a third of the 33.8 that the derivative implies, and the inlets, bays, fuel and equipment around them are not dimensioned in any source used here. If the real aeroplane is more unstable than the middle of the bracket, which is the direction that matters, the supersonic time to double falls at 0.10 per radian from 0.238 to 0.185 seconds. There is no longer a fin to overcome any of it. The tailless delta literature is unusually old and unusually direct about the second point [White and Innis 1959] [Smith 1953] [Harper and Jones 1947].

The X-44A’s wing is known from the journalism, since no specification describes it. It is reported as a modular flying wing with a bulbous fuselage, wings that appear removable, control surfaces along the trailing edge and raked, squared-off wingtips [Lockheed Skunk Works X-44A flying-wing drone revealed] [Exclusive photos, the X-44A breaks cover] [Skunk Works reveals the tailless X-44A]. Modularity is the telling detail, because modular wings on a demonstrator may mean that the wing was a variable under test, although the journalism suggests that they detach for transport.

Structure and the Manufacturing Claim

The X-44A is reported as built from nano-carbon fibre and as a demonstration of rapid manufacturing [Lockheed Martin X-44, the unmanned vehicle] [Lockheed Skunk Works X-44A flying-wing drone revealed]. No mass fraction, no lay-up, no cure cycle and no tooling description has been released, so the claim cannot be checked in the way the aerodynamic claims can. It stands as a stated programme objective that no measurement confirms.

The timeline is the one checkable part of it. DarkStar was terminated in January 1999 and the X-44A was built in 1999 [Lockheed Martin RQ-3 DarkStar] [Lockheed Skunk Works X-44A flying-wing drone revealed]. A complete airframe within a calendar year is the evidence for the manufacturing claim, and apart from the museum’s statement that the airframe was quickly built using advanced manufacturing techniques [Lockheed Martin X-44A, National Museum of the United States Air Force] it is the only evidence in the public record that bears on it.

Sensing Sideslip

The divergence table above says the loop must close in a fraction of a second, and the X-31 report names what that costs. Its lessons concern sensor-related issues and their importance both to simulating a tailless configuration and to controlling a directionally unstable one [Bosworth and Stoliker 1996]. Sideslip is small and is measured in a flow field that the aeroplane itself distorts, and a boom or vane is the kind of protrusion a stealth configuration exists to avoid. The flush alternative has flown. A matrix of nose pressure orifices on the F-18 High Alpha Research Vehicle measured angles of attack and sideslip with a pneumatic frequency response beyond 10 hertz, and aerodynamic lags in the aircraft’s own flow field degraded it during heavy manoeuvring [Whitmore, Moes and Larson, Preliminary results from a subsonic high angle-of-attack flush airdata sensing system].

The obvious way to size that requirement is to ask what a measurement error costs, and the answer is that static accuracy is not what binds. A sideslip error is indistinguishable from a real sideslip, so it commands a real moment,

\[\Delta C_{n} = \left| C_{n\beta} \right| \varepsilon_{\beta}\]

and the gearing from sideslip to nozzle follows from the required-deflection relation already displayed,

\[\frac{d \delta}{d \beta} = \frac{q S b \left| C_{n\beta} \right|}{F_{g} \, \ell \, \cos \delta}\]

Both come out mild. The gearing is 1.13 nozzle degrees per sideslip degree at the demonstration point and 1.35 on the approach, and a half-degree measurement error costs 2.9 percent of the available authority. A static accuracy requirement of half a degree is not a hard requirement.

What survives is the dynamic requirement, which the budget above sets. The loop must close inside sixty to ninety milliseconds supersonically, so the sensor’s lag and its noise at the crossover frequency are the binding properties rather than its static accuracy.

The tension in the MANTA concept is therefore narrow but real. The aeroplane deletes its fin to reduce its radar cross section, and the deletion creates a hard requirement for a fast measurement of sideslip, which a low-observable nose must supply through flush ports whose speed is limited by the aeroplane’s own flow field. No public source explains how the MANTA proposed to resolve even the narrow version, and the absence is left unfilled.

The Flight Test Record

Three flight records are relevant here, and only one of them belongs to an aeroplane called X-44.

What the X-31 Flew

The quasi-tailless experiment is the substantive flight record for the MANTA’s question. The technique was to use the rudder to cancel the stabilising effect of the vertical tail, and then to restabilise and control the aeroplane with yaw thrust vector commands [Bosworth and Stoliker 1996]. The cancellation is a scheduled rudder command, involving no mechanical change, so it can be written down. With $\kappa$ the fraction of the tail to be removed,

\[\delta_{r} = - \kappa \, \frac{C_{n\beta, \text{tail}}}{C_{n \delta_{r}}} \, \beta\]

Setting $\kappa$ to one gives the hundred percent case that was flown and any smaller value gives a reduced-tail aeroplane, which is how one airframe produced a family of configurations instead of a single data point. The gearing is steep. A tail contributing 0.15 per radian against a rudder worth 0.0788 per radian demands 1.9 degrees of rudder for every degree of sideslip, so the technique spends most of a real control surface to simulate the absence of one. The result is a real aeroplane behaving like a tailless one without building a tailless one, possible only because the aeroplane already carried thrust vectoring paddles for a different purpose [Rockwell-MBB X-31] [Huber and Schellenger 1994] [Bosworth and Stoliker 1996]. The series began in March 1994. The demonstration condition was Mach 1.2 at 37,500 feet with a simulated one hundred percent vertical tail reduction, and the manoeuvres flown were doublets, bank-to-bank rolls and wind-up turns. The quasi-tailless mode was also flown subsonically in precision approaches and ground attack profiles [Huber and Schellenger 1994] [Bosworth and Stoliker 1996].

Its conclusion is unambiguous and is quoted here because the wording matters. Flight test and supporting simulation demonstrated that the quasi-tailless approach is effective in representing the reduced stability of tailless configurations, and that thrust vectoring could be effectively used to stabilise a directionally unstable configuration and provide control power for manoeuvre coordination [Huber and Schellenger 1994]. Tailless and reduced-tail fighter aircraft are, in the report’s word, definitely feasible, with the qualification that the capability must be designed in from the beginning [Bosworth and Stoliker 1996].

That qualification states the MANTA’s difficulty in one clause. The MANTA was a conversion.

One thing the demonstration did not do was fly an approach on vectoring alone. Its precision approaches were flown at 40 and 50 percent tail reduction in low turbulence or clear air, and no crosswind approach is reported [Bosworth and Stoliker 1996]. The arithmetic above explains why a crosswind approach on vectoring alone could not have been flown.

What the X-44A Flew

It first flew in 2001, and the released record adds only summary figures and general statements. The museum gives a maximum speed of 176 miles per hour, an endurance of 1.5 hours and a range of 230 miles, and says that the aircraft refined tailless aerodynamics and flight controls, improved Lockheed Martin’s unmanned command and control system and supported a deck-handling demonstration for United States Navy carriers [Lockheed Martin X-44A, National Museum of the United States Air Force]. The number of flights is unknown. The dates are unknown. The altitude envelope is unknown. No incident or measurement is on the public record. The aeroplane survived, which is inferable from its presence in a museum and from nothing else.

A vehicle that flew and produced data that remains unreleased is a different epistemic object from a vehicle that never flew.

What the MANTA Flew

Nothing. No airframe was built. The programme ended with funding, not with a flight or a failure.

Comparison With Ground Prediction

Of the three flight records, only one can be set beside a prediction, and most of what it can be set beside was written after the flight. No ground prediction for either vehicle called X-44 is public, so the comparison draws on the X-31 record and on the arithmetic under Sizing From First Principles.

For the MANTA the ground record is a list of claims and the flight record is empty. Its advertised benefits are given under The Research Question, and nothing flew to test them. The single measurement behind its hardware is a wind tunnel result with no flight counterpart on this aircraft, the sidewall yaw-flap measurement described under The Nozzle the F-22 Does Not Have, and yaw flaps of that kind were never flown on a MANTA because there was no MANTA.

For the X-31 the comparison is between simulation and flight, and the report states its outcome as a conclusion rather than as a table, the conclusion quoted under What the X-31 Flew. This article reports no numerical prediction made before those flights and no figure for how closely the simulation matched them, and it does not supply one.

The derivations above meet the X-31 record in two places, and in a third only in kind. The first is coverage, the factor of 1.135 by which the flown point stands above the worst supersonic condition, or 1.078 when jet velocity varies. It describes what the flown point covers, and no flight tested it as a prediction. The second is sensing, where the loop budget of The Divergence and the Loop That Must Hold It meets the report’s lessons on sensor-related issues. Agreement there is in kind only, since the article quotes no latency figure from the report.

The article’s strongest prediction has no flight to be compared with, and the report anticipates it only in kind. The report notes that thrust vector control power is proportional to the engine power setting, so that landing may require drag devices to hold a higher power setting, and it lists among its lessons that flying on drag devices at an increased power setting can introduce additional directional instability [Bosworth and Stoliker 1996]. Its precision approaches were flown at 40 and 50 percent tail reduction in low turbulence or clear air, so the throttle result of The Throttle on Approach is a prediction that no flight has tested.

For the X-44A there is no ground prediction in the public record and no released flight data beyond the museum’s summary figures. The published speeds bound the wing loading derived for it and exclude a cruise at a reconnaissance ceiling, and the published endurance agrees with the programme’s stated purpose, so the comparison the record allows checks the assumed mission rather than the aircraft.

What the Data Changed

The three lines diverge sharply here and the divergence is instructive.

The tailless design literature continued after the X-31’s quasi-tailless result. The innovative control effector programmes of the later 1990s studied tailless fighter configurations [Montgomery et al 1998], and the record cited here does not trace how far they drew on the X-31 flights.

The X-44A’s line is visible in hardware. It sits between the DarkStar and the Polecat. Its configuration family, a small tailless flying wing with a low-observable planform, is that of the Polecat and the RQ-170 and not that of the DarkStar [Skunk Works reveals the tailless X-44A]. The published assessment is that it belongs with the mid-2000s designs rather than the 1990s ones despite being built in 1999, in effect a claim that a demonstrator can be ahead of its programme.

The MANTA changed nothing that can be demonstrated. The sixth-generation fighter studies in the survey treat tailless control and signature as requirements of their own [Kim et al 2025] [Zhaxidaji 2026], but none of them names the MANTA, and no source cited here traces a lineage from it, so this article asserts none. What can be said is narrower and firmer. The tailless fighter remains a feature expected of the next generation rather than one in service, a 2025 review naming the F-22, F-35 and Su-57 as the operational fifth generation and tailless designs as anticipated in their successors [Kim et al 2025], and the arithmetic above suggests one reason, since the concept as the MANTA stated it holds up in the air and fails at the runway.

The survey below maps the field these two vehicles sit in, and the twenty-five research records that the argument cites stand in its cluster rows with the rest. Every record is assigned to exactly one cluster. The rule that admits a record, and the classes it excludes, are stated in the Source Base.

A cluster’s size measures how much has been published near a topic. It does not measure how important that topic is to these vehicles. The largest cluster holds flight control law design, which bears on both vehicles and enters the argument only through the loop budget, while the cluster holding this article’s keystone, being the tailless configuration itself, ranks eighth of twenty-five. Two of the clusters below cover the subjects of this article’s conclusions rather than its topics, being the approach and crosswind case and the engine failure case.

What the Shape of the Survey Says

Three features of the distribution are worth naming.

The tailless cluster is smaller than the thrust vectoring cluster, and that ordering is the wrong way round for the subject. Tailless aircraft are the application and thrust vectoring is one of several mechanisms, so a literature organised around the problem would put the problem first. It does not, because thrust vectoring is a nozzle technology with a propulsion community of its own publishing in dedicated venues, and it accumulated papers whether or not any tailless aeroplane was being built.

The median publication year is 2005 and 33.5 percent of dated records are from 2015 or later, which for a subject whose defining flight experiments happened in 1994 and 2001 means the field did not stop when the programmes did. The control-allocation and unmanned clusters carry more of that recent weight than any other cluster. The tailless configuration question is being asked again, by a different community, about aeroplanes with no pilot in them.

705 records predate 1970 and they are not decoration. The configuration has a documented history running from the 1920s, longer than the jet age [Wooldridge, Winged wonders, the story of the flying wings]. The tailless and all-wing stability literature of the 1940s and 1950s asked the same question with slide rules and free-flight models, and the answer it reached, that the configuration is controllable and the controls have to be unusually powerful and unusually fast, is the answer the 1994 flight experiment reached again with a digital flight control system. A field that rediscovers its own conclusion fifty years later is telling the reader something about which part of the problem was ever really open.

Control effectors, allocation and flight control law design

The largest cluster, and it holds what replaces a rudder when there is no rudder. Control allocation for redundant and unconventional effectors, flight control law design for unstable airframes, dynamic inversion, adaptive, reconfigurable and fault-tolerant control, fly-by-wire architecture, and the actuator literature that sets the bandwidth the divergence calculation demands. This cluster carries more of the recent weight in the survey than any other, with 399 records from 2015 or later, because allocation among many weak effectors is the problem a tailless unmanned aircraft actually has.

Engine cycle, installation and inlet integration

Where the corrected-flow model at the centre of the derivation comes from. Engine cycle analysis, installed performance, inlet total pressure recovery, afterburning, propulsion station nomenclature and airframe integration.

Delta and swept wing aerodynamics at angle of attack

The wing the MANTA proposed and the flow it would have lived in. Delta wing vortex aerodynamics, leading-edge behaviour, high angle of attack, post-stall, buffet, spin and flow separation. A tailless delta at high angle of attack is where the forebody starts generating yawing moments of its own, which is a mechanism the article names in the framing section and does not quantify.

Thrust vectoring and propulsive control

The mechanism the article’s keystone rests on, and it is larger than the problem it solves. The cluster holds nozzle vectoring measurements, multiaxis control power studies, post-stall manoeuvring work, fluidic vectoring, the flight programmes that carried vectoring hardware for other reasons, and the thrust vector control of rockets, missiles and spacecraft, which deflects the same momentum flux for the same purpose.

Unmanned aircraft, autonomy and the reconnaissance mission

A cluster that bears on one of the two vehicles and not on the other. Unmanned combat and reconnaissance aircraft, their design, configuration, flight control and flight test, the programmes from the DarkStar onward, and the recent collaborative combat aircraft and air-combat decision work. Its size is a fact about recent aeronautics and not about the X-44A, which was flown before most of it was written, and 54 percent of its dated records are from 2015 or later.

Supersonic and transonic aerodynamics

The speed range in which the article’s minimum lives. Shock waves, wave drag, area ruling, compressibility and the transonic and supersonic characteristics of fighter configurations. The result that the authority ratio has a minimum near Mach 1.67 is a propulsion result rather than an aerodynamic one, and this cluster is where the aerodynamic side of the same speed range is recorded.

Tailless configurations and the missing vertical tail

This is the cluster the article is about and it is not among the largest, which is a statement about publishing and not about importance. It holds the tailless and all-wing stability literature from the 1940s onward, the vertical tail sizing and tail reduction studies, the blended wing body work that inherited the same problem for a different reason, and the modern tailless unmanned configurations. The oldest records here and the newest ones are asking the same question, which is how a configuration with no fin is to be kept pointing where it is going.

Nozzles, exhaust systems and internal performance

The hardware the vectoring has to be built into. Convergent-divergent nozzle internal performance, thrust coefficients, expansion ratios, ejectors, plug nozzles, thrust reversers and the nozzle geometry studied for its exhaust noise. This is the cluster that would decide whether the sidewall yaw flaps the MANTA needed cost more in cruise thrust than they bought in control, which is a question the article raises and does not answer.

Directional stability, sideslip and the lateral-directional modes

The dynamics the missing fin changes. Sideslip derivatives, Dutch roll, weathercock stability, departure criteria and the estimation methods that produce the derivative this article had to bracket rather than quote. The article’s inability to name a value for the tailless yaw derivative is not for want of a literature on how to measure one.

Handling qualities and the pilot in the loop

The discipline that decides whether an aeroplane is acceptable rather than merely controllable. Rating scales, pilot-induced oscillation, workload, pilot models and simulator evaluation. It bears on the MANTA and not at all on the X-44A, and that asymmetry is the clearest illustration in the survey that these are two different aeroplanes.

Wind tunnel testing, computation and validation

How anything here is known. Wind tunnel technique, computational fluid dynamics, turbulence modelling, grid generation, wall interference and flight correlation. The nozzle control power measurements the article leans on are wind tunnel results, so the reliability of this cluster’s methods is the reliability of the article’s second-strongest source.

Airframe structure, composites and manufacture

The X-44A’s stated programme objective and the part of it that cannot be checked. Composite structure, laminates, structural design, fatigue, buckling and rapid manufacturing. No released figure connects this literature to the aircraft, so the cluster stands as the field the manufacturing claim was made inside rather than as evidence for it.

Aircraft conceptual design, sizing and drag

The working relations of the design texts the article cites. Conceptual and preliminary design, weight estimation, design optimisation, drag prediction and fighter configuration studies. The tail volume coefficient, the drag polar and the Oswald factor that the derivations use are this literature’s tools, and the article uses them in their textbook forms.

The atmosphere, turbulence, gust response and load alleviation

The flight condition the crosswind identity simplifies. The standard atmosphere, atmospheric turbulence models and measurements, aircraft response to gusts and active gust load alleviation. The crosswind identity treats a wind as a fixed lateral velocity, and this cluster is where the statistics of real winds and gusts are recorded.

Approach, landing and the crosswind case

This cluster covers the subject of the article’s strongest conclusion, that pure thrust vectoring cannot meet a crosswind landing requirement. It holds crosswind technique, approach and landing handling qualities, automatic and carrier landing, wind shear on approach, and landing rollout directional control.

Survivability and vulnerability of military aircraft

The discipline that weighs a signature against everything else. Survivability design and assessment of combat aircraft, susceptibility and vulnerability. Signature reduction is one term of survivability, which is why the premise the article takes from the low observable cluster is a trade rather than an absolute.

Engine failure, asymmetric thrust and minimum control speed

The second of the two identities the article derives. Minimum control speed is the regulatory form of exactly the calculation this article performs, being the speed below which a fin can no longer hold an engine failure, and it is the quantity the tangent relation makes speed-independent for a thrust-vectored aeroplane.

Where the Framing Breaks Down

Five places, and only the first of them is quantified here.

The ratio treats jet velocity as constant across the envelope, which it is not. Relaxing that assumption moves the answer in the article’s favour. Carrying the jet velocity relation through the ratio gives

\[\mathcal{R}(M) \propto \frac{\eta_{r}(M) \left( 1 + 0.2 M^{2} \right)^{3} V_{j}(M)}{M^{2}}\]

and at an overall engine pressure ratio of eight the jet velocity rises by 25.7 percent from the approach to Mach 2.25, which is far from constant.

  minimising Mach demonstrated point above the worst case
constant jet velocity 1.674 1.135
varying jet velocity 1.550 1.078

The minimum moves forward and gets shallower, so the demonstrated point stands 7.8 percent above the worst supersonic condition rather than 13.5. The conclusion drawn from the pessimistic assumption survives the correction and improves. The result is also robust to the one engine parameter it introduces. Across overall pressure ratios from four to twenty the minimising Mach moves only from 1.502 to 1.589 and the penalty from 5.9 to 9.5 percent.

What the correction does change is the top of the envelope. Under the constant assumption Mach 2.0 and Mach 2.25 were harder than the demonstrated point. With the jet velocity varying they are easier, at 1.006 and 1.103 times, so the high supersonic end stops being a concern. The minimum’s existence never depended on the assumption, because it comes from the mass flow term, and only its location and depth did.

A second approximation remains unquantified and runs the other way. The relation above assumes the afterburner is lit, and a dry-thrust case has a lower total temperature and a lower jet velocity, which would make those conditions less favourable than any table here. This article does not compute the dry case, and the envelope should not be read as covered.

The engine-out identity assumes the vectoring is available on the live engine at full deflection. A nozzle that has failed for the same reason the engine has failed provides nothing, and a common-cause failure of an engine and its nozzle is a case a fin covers and a nozzle does not. The argument belongs to reliability engineering, outside aerodynamics, and no quantitative form of it is attempted.

Treating the two vehicles in one article follows from the designation, and engineering supplies no reason for it. They share a contractor, a decade and a number. They share no requirement, no size class, no speed range and no mission. A reader interested in either aeroplane is being handed a good deal of material about a different one, justified because the collision is the subject.

The crosswind case assumes the aeroplane must land in a crosswind on a runway. A vehicle that lands into wind on a long runway at a test range faces a much weaker requirement than an operational fighter does, and the MANTA as an X-plane would have been the former. The impossibility derived above is a statement about the operational aeroplane the MANTA was a step toward, not necessarily about the demonstrator, and the distinction holds even though every published description of the MANTA frames it as a step toward a fighter.

The Source Base

The argument in this article rests on nine documents and the rest of the reference list is a map of the surrounding literature.

Two carry the flight result. The X-31 quasi-tailless demonstration description [Huber and Schellenger 1994] and the flight test results report [Bosworth and Stoliker 1996] supply the flight condition, the technique, the manoeuvres and the conclusion. Everything this article says about what has actually been demonstrated comes from these two.

One carries the nozzle. The measurement of multiaxis control power from a two-dimensional convergent-divergent nozzle with sidewall yaw flaps across Mach 0.20 to 2.47 [Capone and Bare 1987] is the evidence that the hardware the MANTA needed can be built and characterised.

One carries the alternative. The study of differential canard deflection as a yaw generator on the X-31 with and without its vertical tail [Whiting 1996] establishes that an aerodynamic yaw effector of comparable authority to the vectoring vanes was studied on the same aeroplane, which is what makes the low-speed conclusion above a design choice rather than a dead end.

Five carry the vehicles themselves and none of them is a primary document. The MANTA and unmanned X-44A encyclopaedia entries [Lockheed Martin X-44 MANTA] [Lockheed Martin X-44, the unmanned vehicle], the journalism that broke the story [Lockheed Skunk Works X-44A flying-wing drone revealed] [Skunk Works reveals the missing link in a secret unmanned history], and the museum fact sheet [Lockheed Martin X-44A, National Museum of the United States Air Force] are the core of the public record on these two aircraft, which the 2003 NASA inventory of X-vehicles [Jenkins, Landis and Miller, American X-Vehicles, An Inventory X-1 to X-50, NASA SP-2003-4531, 2003] and two secondary compilations [X-44 MANTA Multi-Axis No-Tail Aircraft, GlobalSecurity] [Lockheed Martin X-44 MANTA tailless technology demonstrator proposal] supplement. That is a thin foundation and the article is built to survive it, which is why the analysis of the MANTA rests on the F-22’s published numbers and the X-31’s published flight results, and why the one X-44A result is stated as a bound on the museum’s figures.

Two sources are used with a stated reservation. The two National Museum of the United States Air Force pages return a Hypertext Transfer Protocol status of 403 to automated requests, which is bot mitigation and not absence. Both were read through copies held by the Internet Archive, since neither could be read directly from the museum’s own site.

The research survey holds 9,631 records, of which 9,182 resolve through Crossref digital object identifiers and 449 through NASA’s Technical Reports Server. The median publication year is 2005. Of the 9,341 dated records, 705 were published before 1970, being 7.5 percent, and 3,128 in 2015 or later, being 33.5 percent.

Counting a displayed relation as cited when the paragraph next before or after it carries a citation, 45 of the article’s 59 displayed relations carry none. That gap remains open.

The Definition of Primary

Primacy is a property of the document, and this survey derives it from the identifier. A record is primary when it comes from NASA’s Technical Reports Server or carries a Defense Technical Information Center, American Institute of Aeronautics and Astronautics, SAE International or Office of Scientific and Technical Information identifier, and it is a report primary when it is a NASA or Defense Technical Information Center record. By that rule 5,625 of the 9,631 research records are primary, being 58.4 percent, and 1,317 are report primaries, being 13.7 percent. That second figure matters most, because the relations this article displays were established in report series that a search of journals and conferences cannot see at all.

Eleven foundational primaries carry relations this article displays, and a search returning something adjacent would be worse than useless for any of them. They are Munk on the aerodynamic forces on airship hulls, Multhopp on the aerodynamics of the fuselage, Allen and Perkins on viscous flow over slender inclined bodies, Oswald on the calculation of airplane performance, the U.S. Standard Atmosphere, Gilruth on requirements for satisfactory flying qualities, Campbell and McKinney and Toll and Queijo and Jones and Alksne on lateral derivative estimation, and two in-flight evaluations of pure control system time delays. Every one is cited in the prose beside the relation it establishes rather than only in the reference list.

Thin Subjects

The subjects the derivations rest on are well covered when asked for in the field’s own vocabulary, which speaks of directional stability and control, the vertical tail, the empennage and lateral-directional characteristics rather than of tail sizing. Counting the research titles that match a fixed pattern for each subject, and counting as a report primary a record from NASA’s Technical Reports Server or the Defense Technical Information Center, vertical tail sizing and the directional requirement returns 218 records with 35 report primaries, the slender-body fuselage contribution 252, the drag polar and span efficiency 51, and loop bandwidth with transport delay 38.

Four subjects that this article’s derivations depend on have thin literatures. Each count below is the number of research records in this survey whose title carries at least one of the listed terms.

Subject Title terms counted Records
the standard atmosphere standard atmosphere, atmospheric model, density, pressure, temperature or properties, tropopause, altitude variation or effect on density or pressure 2
wing internal volume and fuel fuel volume, tank, capacity, fraction, system or load, internal volume, wing volume, tankage or thickness, volumetric, thickness ratio 3
thrust lapse and the corrected-flow model corrected flow, mass, airflow, parameter, speed or weight flow, thrust lapse, lapse rate, thrust variation or change with altitude, Mach or speed, engine performance at altitude 2
quasi-tailless technique and in-flight simulation quasi tailless, in-flight simulation, variable stability, simulated tail or instability, tail off simulation, airborne simulator 21

Each is thin for one of the three recognised reasons. The standard atmosphere returns two records, both of them the standard tables themselves, because it is so settled that it stopped generating papers and became a standards document instead, which is cited as one. Wing internal volume returns three records and none of them concerns how much volume a wing encloses, two being composite structures that carry a fuel tank and the other the aerodynamics of wing thickness, because that relation lives in design textbooks and not in the report literature, and it is cited to books accordingly. Thrust lapse and the corrected-flow model return two records, both on matching engine and aircraft lapse rates for a high-speed civil transport, for the same reason, and the article takes that model from propulsion texts and calibrates the lapse exponent itself. Quasi-tailless technique and in-flight simulation returns twenty-one records with eleven report primaries, and it is small because the field is small, one aeroplane having flown the experiment inside a variable-stability tradition that is itself narrow. Naming which kind each one is matters more than the counts, because none of the four is a gap that searching could close.

The subject of this article’s framing cannot be surveyed by bibliographic search at all. The survey holds no cluster on designation practice, because designation, classification, records, identifier and secrecy are among the least discriminating words in any literature, and the nine research titles in it that carry designation or nomenclature use those words for propulsion station numbering, aerodynamic and aircraft nomenclature, aerofoil series and a company project number. No title in the survey names the X-44 or the MANTA. That is a fourth kind of thin beyond the three the series recognises, and the real sources for the subject are the designation registries themselves, which this article cites in the Reference category and quotes in the section on the two referents.

What the Survey Admits

A record is admitted only when a person reading its title finds it on this article’s subject. The subject is directional stability and control and the vertical tail, tailless and flying-wing aircraft, thrust vectoring, exhaust nozzles, engine cycle and inlet performance, delta and swept wing, supersonic and slender-body aerodynamics, flight control, handling qualities, approach and landing, low observability and survivability, aircraft design and performance, unmanned aircraft as aircraft and as military systems, airframe structure and manufacture, wind tunnel and flight test and air data, the atmosphere as the flight condition, engine failure, and aircraft programmes and their history. Every record is filed under a named literature, and the survey has no residual cluster.

Many words this subject depends on also name something else, and a record that shares only such a word or a distant application is excluded. Yaw, roll, rudder and autopilot also belong to ship steering, yaw, sideslip and torque vectoring to road vehicle dynamics, crosswind and the wind tunnel to civil wind engineering and railway aerodynamics, and wing, flight, lift and drag to the flight of insects, birds and bats. Nozzle also names the cavitating nozzles of hydraulics and the process nozzles of steam, refrigerants and powder atomisation, the pilot stage of a hydraulic valve is not a person, the blended wing body is an underwater vehicle configuration in the identical phrase, and aerofoils are also wind turbine blades. Unmanned vehicles also run on the ground and on the sea surface and serve agriculture, mapping and inspection, fighter also names the fire fighter, reconnaissance also has its ground military senses, radar cross section is also measured on ships, and spacecraft trajectories and drag reduction in water have literatures of their own. Aeronautical subjects that the argument does not use are excluded as well, among them icing, aircraft noise and the sonic boom, rotorcraft, airline and airport operations, air traffic management, aircraft subsystems and maintenance, flutter, and the combustion, cooling and materials of gas turbines.

Records that are not works are excluded as well. Crossref registers peer reviews as records whose titles read as a review of a named paper and supplementary files as components sharing an identifier stem with their parent, and military part specifications carry titles that are noun phrases inverted for filing. Corrections, errata, retractions, withdrawals, figures, supplementary material, peer-review reports, front matter, whole conference volumes that state no subject, and standards for parts, materials, test methods and documentation are parts of works, editorial events or specifications rather than works. Reviews of books, dictionary and other reference entries of two pages or fewer, news and other notices, and a second deposit of a document already in the survey are not admitted either, while an authored encyclopedia article of more than two pages and a textbook chapter are research works and stay. None of these makes a claim, so none is counted.

Some records of doubtful relevance are kept, among them rocket, missile and spacecraft thrust vector control, the radar and infrared signature of rotorcraft, the directional stability of birds and the yaw control of flapping flyers, which need no vertical tail, aircraft designed for Mars, gust load alleviation, and control theory that names time delay, actuator saturation or control allocation without naming an aircraft. Each shares a mechanism, a configuration question or a relation with this subject, and a reader may weigh it accordingly.

Every research title has been read for relevance, so the off-topic share that remains is a matter of reading judgement.

Epistemic State

Historical Fact

The X-44 MANTA was a Lockheed Martin design study of a tailless F-22 derivative controlled by three-axis thrust vectoring. Preliminary work was under way by May 1999 and the National Aeronautics and Space Administration approved a programme start in June 1999. No aircraft was built.

The X-44A unmanned aircraft was built by Lockheed Martin Skunk Works in 1999 and first flew in 2001. It has a span of about 30 feet, is powered by a Williams F112, was first reported in February 2018 and was publicly unveiled in March 2018. It has been displayed at the National Museum of the United States Air Force since October 2020.

The X-31 flew a quasi-tailless flight demonstration beginning in March 1994, at Mach 1.2 and 37,500 feet with a simulated one hundred percent vertical tail reduction, and its report concludes that tailless and reduced-tail fighters are feasible when the capability is designed in from the start.

The F-22’s F119 nozzles vector in pitch only, through plus or minus twenty degrees.

The DarkStar was terminated in January 1999 and the Polecat first flew in 2005.

Verified by Independent Derivation

The identity $q = 0.7 p M^{2}$ agrees with the density form at every flight condition used, to one part in a million or better.

The cancellation of static pressure from the authority ratio holds numerically at five altitudes above the tropopause, to one part in ten to the twelfth, and the closed form agrees exactly with the full atmosphere model at three further altitudes.

The minimum of the ideal Mach function at $M = \sqrt{5/2}$ and its value of exactly 1.35 are recovered by bisection on a numerically differenced derivative, to six decimal places, independently of the algebra that produced them.

The maximum of the crosswind function at exactly Mach one is recovered by golden-section search to six decimal places, and the altitude independence holds at five altitudes to four parts in ten thousand, the residue being the small-angle approximation to the arctangent.

The engine-out relation $\tan \delta = y/\ell$ is recovered by solving the moment balance numerically without cancelling the thrust, at four thrusts spanning three orders of magnitude, agreeing to one part in a billion.

The two expressions for the best lift to drag ratio agree to machine precision. This tests transcription, since at the best ratio the induced drag equals the zero-lift drag exactly and the two forms are the same statement.

The demand-over-availability ratio was derived a second time from the propulsive tail volume by a route that shares nothing with the first, and reproduces the throttle factor of 5.33 to three significant figures.

The remaining derived values can be recomputed from the relations shown, among them the rudder baseline, the crosswind maximum, the small-angle error and its variation, the gearing, the loop budget, the slender-body inversion, the quasi-tailless gearing, the drag polar and the varying jet velocity.

Analysis

The ratio of thrust-vectored yaw authority to aerodynamic yaw demand is independent of pressure altitude and, above the tropopause, a function of Mach number alone. This follows from static pressure entering the engine mass flow and the dynamic pressure to the same power.

That function has a minimum at Mach 1.581 with ideal recovery and Mach 1.674 with a military specification inlet recovery model. The X-31’s demonstrated point at Mach 1.2 stands 1.135 times above the second, and no point from Mach 1.2 to Mach 2.25 is more than twelve percent harder than what was flown.

For a crosswind of fixed speed, the required vector angle depends on Mach number alone and peaks at exactly Mach one. Pressure and temperature both cancel.

Restoring the demonstrated margin on a sea-level approach at 150 knots in a 15 metre per second crosswind requires 38.4 percent throttle against the 7.2 percent the glide slope needs at an assumed landing ratio of six, a factor of 5.33, or against 12.4 percent at the ratio of about four measured on a straight-wing fighter, a factor of 3.09. The implied lift to drag ratio in level flight at that thrust is between 1.6 and 1.9, below the lowest effective ratio of 2.7 flown in the low lift to drag landing research.

The directional divergence of a tailless F-22 has a time to double between 0.16 and 0.91 seconds across a wide bracket of the two unpublished quantities it depends on, and the entire supersonic column of that bracket is below four tenths of a second.

A thrust lapse exponent of 0.960 in density ratio reproduces the DarkStar’s published ceiling, weight and thrust on an assumed 42 square metre wing, an Oswald efficiency of 0.85 and a zero-lift drag coefficient of 0.015.

Primary sources stand at 5,625 of 9,631 research records, or 58.4 percent, and report primaries alone at 1,317 or 13.7 percent. Records from 2015 or later number 3,128, or 33.5 percent of those dated, and 705 records predate 1970.

Relaxing the constant jet velocity assumption moves the minimising Mach from 1.674 to 1.550 and cuts the demonstrated point’s penalty from 13.5 percent to 7.8, so the conclusion drawn under the pessimistic assumption survives its own correction and improves. Across engine pressure ratios from four to twenty the minimising Mach moves only from 1.502 to 1.589.

Expressed as a propulsive tail volume, the vectoring supplies 0.0181 at the demonstration point against about 0.0412 for thirty degrees of a conventional rudder, or 44 percent, and 5.19 times as much at maximum thrust on approach. The same quantity collapses to 0.0154 at glide-slope thrust, which is the throttle result arrived at from the other direction.

The stabilisation loop must close within 60 to 90 milliseconds supersonically and 145 to 218 on approach, from a crossover of two to three times the unstable pole and thirty degrees of phase margin budgeted to transport delay.

Inverting the slender-body yawing moment for the fuselage volume that the assumed derivative implies gives 33.8 cubic metres, a mean cross-section of 1.79 square metres over the F-22’s length. No fuselage volume is published to compare with, and the two engine envelopes alone account for about a third of that volume, so the instability bracket is reported as a bracket and not as a conservative bound.

Inference

The MANTA required a nozzle capability the F-22 does not have, since a two-dimensional convergent-divergent nozzle deflects only in the plane of its flaps. This is inferred from the published nozzle description, and one MANTA account states the requirement directly in giving the aircraft pitch and yaw vectoring nozzles [X-44 MANTA Multi-Axis No-Tail Aircraft, GlobalSecurity].

Pure thrust vectoring cannot meet an operational crosswind landing requirement, so a tailless fighter needs an aerodynamic yaw effector that works at low speed. The throttle calculation supports this inference, which is consistent with the X-36’s split ailerons and with the X-31 differential canard study, neither of which is offered as confirmation.

The X-44A’s wing loading is at most about twice the DarkStar’s, and below it if the aircraft cruised above about 23,000 feet, an inference from the museum’s speeds and an assumed drag polar and aspect ratio common to both. A cruise at a reconnaissance ceiling would need about twice the published maximum speed.

The X-44A’s published maximum speed is not a thrust limit on a clean polar, since the engine makes about five times the clean drag at the bound, so either the drag was several times higher or another limit set the maximum.

The X-44A was a short-range configuration and manufacturing demonstrator and not an endurance aircraft. The published endurance and range indicate it, and the stated programme objectives agree.

The stabilisation loop should be machinery rather than a pilot, inferred from the delay budget and the phase margin it reserves. The divergence rate alone is within what practised subjects held in single-axis tracking.

The difficulty in sensing sideslip is dynamic. Writing the relation down gives a gearing near unity and a cost of 2.9 percent of available authority for a half-degree measurement error, which is not a hard requirement. What binds is lag and noise at a crossover of six to nine radians per second.

What the Record Does Not Settle

Whether the designation X-44A was ever officially assigned to either vehicle, and if to one, to which. Both are recorded under it in the general reference literature. The specialist designation registry carries no page for the number at all. No allocation document has been published.

Whether the two programmes had any relationship. The journalism that revealed the unmanned aircraft states that it is unclear how it came to carry the designation and that there appears to be no direct relation. An absence of known relation is not a known absence of relation.

When the MANTA was cancelled. The sources place the end of funding in 2000 or around that year, a 2003 NASA inventory still describes a feasibility study in progress, and none cites a programme document.

Everything about the X-44A’s flight programme beyond the year of first flight and the museum’s summary figures. Number of flights, duration, envelope, instrumentation, results, and whether the aircraft in the museum is the only one built.

Every specification of the MANTA. Wing area, sweep, weights, required vector angles, control law architecture and the intended sideslip sensing. One reference site lists weights and performance for the MANTA without citing a source [Lockheed Martin X-44 MANTA tailless technology demonstrator proposal].

Whether the MANTA influenced any later programme. No source cited here documents a connection to any later programme, and the sixth-generation fighter studies in the survey do not name it.

The DarkStar’s wing area, which this article assumes because no source used publishes it, and on which the thrust lapse calibration and every number in the X-44A table depend, and the X-44A’s aspect ratio, which this article takes from the DarkStar’s.

On Sources Used With Reservation

The two National Museum of the United States Air Force pages refuse automated requests, for the reason given in the Source Base, and both were read through copies held by the Internet Archive.

The general encyclopaedia is the source for the MANTA’s origin dates, its designation and its F-22 derivation, and one journalistic account reports the X-44A’s nano-carbon fibre skin, which a second describes as an all carbon fibre airframe. No primary document for any of those claims has been located, and the X-44A’s engine, performance figures and museum placement rest on the museum fact sheet. The X-44A bound rests on the museum’s performance figures, and none of the article’s other results depends on these sources.

Three secondary aviation outlets are cited for the X-44A’s revelation and description [Lockheed Skunk Works X-44A flying-wing drone revealed] [Skunk Works reveals the missing link in a secret unmanned history] [Skunk Works reveals stealthy UAV demonstrator]. Beside the museum they are the only sources that have published on the aircraft in any detail, they are consistent with each other, and one of them states plainly what it does not know, which is a reason to trust it more.

On Information Postdating the Editorial Date

This article carries an editorial date of 19 November 2025 and is written from knowledge current at the time of writing, which includes the 2018 revelation and 2020 museum placement of the X-44A and the accounts published after them. Later accounts are described as accounts and not as record.

Out of Scope

Fluidic thrust vectoring, which replaces mechanical deflection with a secondary injected flow and changes the weight and signature arguments without changing the momentum balance used above.

The radar cross section calculation itself. The argument takes as given that a vertical tail is a large contributor and does not compute it.

The X-45, X-46 and X-47 unmanned combat air vehicle programmes, which are the next articles in this series and which share the tailless configuration question with the X-44A while answering an entirely different requirement.

Engine-out reliability and the common-cause failure of an engine with its nozzle, named in the framing section as a case a fin covers and a nozzle does not.

The manufacturing claim in any quantitative form, since no mass, lay-up, tooling or cycle-time figure is available.

The F-22’s flight control system, a large subject that bears on this one only through the nozzle.

Conclusion

The X-44 is one number attached to two aeroplanes that share a contractor and nothing else, and the register does not record the collision.

The aeroplane that never existed asked a question that had already been answered. The X-31 flew a fully simulated tailless configuration at Mach 1.2 and 37,500 feet in 1994 and concluded that the configuration is feasible. This article adds a measure of how much of the envelope that one point covered. The answer needs no vehicle data. The static pressure cancels from the governing ratio, above the tropopause the ratio depends only on Mach number, the ratio has a minimum at Mach 1.674 with a realistic inlet, and the demonstrated point stands thirteen and a half percent above the worst case. One supersonic point very nearly covered the supersonic envelope.

The concept fails at the runway instead. For a crosswind of fixed speed both pressure and temperature cancel and the demand peaks at exactly Mach one, so at equal throttle the approach is the easiest case in the envelope. The throttle is not equal. Restoring the demonstrated margin on approach needs three to five times the thrust the glide slope needs, and absorbing that thrust in level flight implies a lift to drag ratio below two. A tailless fighter therefore needs an aerodynamic yaw effector at low speed that it does not need supersonically, the architecture the X-36 flew and the MANTA proposed to delete.

The engine-out case, which is one of the two reasons fins are large, does not size a thrust-vectored aeroplane at all, because the vector angle that trims it satisfies $\tan \delta = y/\ell$ and the thrust cancels identically. Two classic fin-sizing cases, opposite answers, and reasoning from the fin would have got both wrong.

The aeroplane that did exist was built in the year its predecessor was cancelled and flew two years later, and almost nothing about it has been released. The museum’s figures, a maximum of 176 miles per hour, an hour and a half and 230 miles, describe a short-range demonstrator, and a cruise at a reconnaissance ceiling would have needed about twice that speed. They bound its wing loading at no more than about twice the DarkStar’s, and below the DarkStar’s if it cruised above about 23,000 feet, so the wing loading cannot say what the aircraft was for. The endurance can, and it agrees with the programme’s stated purpose of demonstrating a configuration and a factory.

The last observation concerns the designation instead of either aeroplane. The X-planes sequence is a finite resource issued once and never replenished, and a number spent twice is still a number spent once. The register carries no record of the ambiguity, the specialist directory carries no page for the number, and the encyclopaedia has resolved the collision by writing two articles and noting that they appear to be unrelated. The cost of the confusion falls entirely on whoever reads the record later, which in this instance is this article.
