The Super-Fighter That Was Betrayed By Its Engine | Vultee XP-54 [Aircraft Overview #68]

Today we’re taking a look at the Vultee XP-54, unofficially nicknamed the Swoose Goose, which was an experimental fighter that was developed at the start of the 1940s. It came from the same US Army specification that led to the development of the equally experimental Bell XP-52, Curtiss XP-55, and Northrop XP-56.

F.A.Q Section Q: Do you take aircraft requests? A: I have a list of aircraft I plan to cover, but feel free to add to it with suggestions:) Q: Why do you use imperial measurements for some videos, and metric for others? A: I do this based on country of manufacture. Imperial measurements for Britain and the U.S, metric for the rest of the world, but I include text in my videos that convert it for both. Q: Will you include video footage in your videos, or just photos? A: Video footage is very expensive to licence, if I can find footage in the public domain I will try to use it, but a lot of it is hoarded by licencing studies (British Pathe, Periscope films etc). In the future I may be able to afford clips :) Q: Why do you sometimes feature images/screenshots from flight simulators? A: Sometimes there are not a lot of photos available for certain aircraft, so I substitute this with digital images that are as accurate as possible. Feel free to leave you questions below - I may not be able to answer all of them, but I will keep my eyes open :)

The J7W1 was actually intended to be powered by a jet type engine. The propeller version was used basically for testing the concept. Propeller version would have been built and flown until the intended powerplant was ready, if it ever would have been. I always thought that the J7W1 was the most beautiful of all of the concept plane that anyone else ever made.

[@henrikgiese6316]

@Steel Ringer IIRC it didn't have enough engine power to get out of ground-effect flight (WIGE long before the Russians!) so it was arguably not a "real" aircraft. OTOH that was just a power problem. The short flight distance was AFAIK just because of the limited testing area. Incidentally, it was so large it might well have crossed the Atlantic as a WIGE... Now that's an interesting start for an alternate history!

The fact that this plane began life before the USA was even in WWII showed how rapidly aviation design was moving back then.

[@mikedrop4421]

It truly is incredible that we went from bi-planes to jets during one war.

[@aserta]

The thing that most people don't get is that most of our technologies existed in various formats before they became the thing they are. IN this case, all the basic tech regarding airplanes, was already in existence from cars, boats, and gliders. Then at some point, various people across the planet had the thought to put motors on gliders, then they figured out that beyond wing lift this air thing has another effect on bodies so they began skining them using tech like kayak making, then moved on to metal skins, and so on. As for the shape, well, we didn't invent anything regarding that, we just mimicked what nature already did. Slower airplanes have slower profiles, faster airplanes have faster profiles. The funny thing is that once you reach the limit of what you can piece together (the variations on a theme as they were) you reach a bottleneck. SO that's why airplanes can go only so fast, and have shapes that match those speeds, because for example, we still haven't figured how to not turn humans into goop that needs to be scooped up at high speeds, nothing past pressure suits and maybe training and meds.

[@edsutherland8266]

The Westinghouse J40 similarly sank a few otherwise promising designs, so it was far from unusual for engines to doom projects. The problem with the piston engines was that sizes & power outputs were so different, so it wasn’t always easy to just stick a rival power plant in. With early jets, there were often a few options in the same rough size class, so it was slightly easier.

[@jkoysza1]

Another great video. Note: As one with experience in burning magnesium, I would not call using a torch or similar to ignite it, "extremely flammable". Gasoline and oil can be set alight with a match, but an airframe of magnesium, not so much. In comparison, finely divided steel wool can be lit with a match, but one does not call steel extremely flammable.

[@soberedsoldier2578]

From the context of the video, I believe he meant in the circumstances compared to other airframes. You mention magnesium requiring a decent amount of heat to ignite, and while that shouldn’t be extremely flammable on its own, in a combat vehicle it may be so. What I mean is the potential for engine or fuel fires are possible, and even more so in aerial engagements. If the engine catches fire, the normal aluminum airframe still retains most of its structural strength, whereas it sounds like magnesium would ignite the plane at a much more rapid pace. Though he really may have meant it in your sense, too. Interesting, nonetheless.

I've worked an aircraft accident where the engine melted out of the fuselage, after which the movement of CG aft caused it to stall. Both people died.

One of many problems was by the time it was ready it was not needed. The US had no need for a high-altitude interceptor by that point in the war.

If they had needed that plane they could have possibly used the Chrysler IV-2220 but why bother to put another engine and aircraft type into production at that point in the war?

[@elennapointer701]

I bet the aircrews would have come up with some choice nicknames for this thing had it gone into full production. That "ejection seat" is horrifying. Baling out at low level in some planes was possible (two members of John Hopgood's Dambuster Lancaster crew baled out at around 200ft as the plane disintegrated, and survived, albeit injured) but jumping from the Goose at low level would be a guaranteed death sentence. Mind you, with all that magnesium, the funeral pyre would have been bright.

@@Rapscallion2009 Still burns like a mofo if it gets hot enough. I've worked with firefighters, SOP for a magnesium fire is to just stand back and watch it burn, because water only makes it worse -- it's so hot it breaks the water into hydrogen and oxygen, which then burn back into water.

[@oldgringo2001]

Yeah, pushers are prolific in video games. They look like they should be faster. But they ain't in real life. I'm old enough to remember what a B-36 sounded like when it took off overhead, six turning and four burning. Even with four jet engines bolted on and five cannon-armed turrets, it didn't have a chance in hell against a Mig-15. But it was great for Texas, where they were built! Back in 1988 I sat through a lecture about where they were going to build the Superconducting Supercollider. After the lecture, I talked to the physicist who had delivered it, and set him straight: If it was built at all, it would be built in Texas. Why? Because thanks to the Electoral College, the Federal Government is a life support system for Texas. And guess what, I was absolutely right. The best thing that came out of the failed project was the hilarious Herman Wouk novel *A Hole in Texas*. Billions of dollars for a hole in the ground. Well, a BIG hole in the ground.

By the sound of it whoever called the Vultee that thought much the same about it!

Excellent Rex. Love how you present info on these obscure aircraft.

[@stephenremington8448]

Great looking unusual plane, shame it didn't work out. Interestingly Vultee joined up with Consolidated to become Convair and built the mighty legend, the B-36. About magnesium, it has commonly been used in the aviation industry for parts of planes, especially in the engines, from the Bf109 up to Airbus and British Aerospace, the main concern has always been corrosion. People know the thing from school, the magnesium ribbon put in a flame, but solid magnesium is a lot harder to burn, it has to be heated to melting point with continued sustained heat to catch fire. Aluminium has the same sort of melting point, aluminium powder has been used in rocket propulsion.

I picked this aircraft because it was designed by Curtiss which I'm working on a book on the Curtiss P-40 Warhawk and I find it interesting that Curtiss participated in the contest while continuing with the development of the XP-40 (I don't know if the company did both at the same time before the US officially entered WW2) and I say officially because of the Flying Tigers that helped defend China from Japan until the attack on Pearl Harbor that changed the future of the mercenary group known as the Flying Tigers and the ultimate disbandment of the group (I got off tracked).

The F-104 also had a downward firing ejection seat because of it's high vertical tail. In air craft designed to take off and rapidly climb to altitude to intercept Warsaw Pact intruders - this was not considered a problem. Then - some of the nations buying them - such as Germany - wanted the F-104's to serve as ground attack aircraft as well ... Of course ... all aircraft must land and take off - which pretty much by definition happens at "low altitude" and thus people eventually saw the need for Zero Altitude Ejection Seats. .

^ Nope. The F-104 was not good in the GA role, as illustrated by the fact it was not even popular with the USAF, as a Day Interceptor. (a role that unlike GA, requires different [and heavier] avionics, and a larger weapons load) The F-104 had an underpowered engine (one reason for its lightweight build), couldn't carry the radar the USAF wanted, and originally had none of the features of an All Weather Interceptor. The FRD regime in Bon was bribed into accepting an inferior product; one that various Luftwaffe pilots would pay for with their lives, and also resulted in a weaker air defence against airspace incursons by the GDR/USSR, than alternatives could have provided.

[@donjones4719]

I knew 2 out of the 4 planes from this contract/specification - not this one. A very interesting story.

[@sgthop]

@Cancer McAids I'm...not entirely sure what you're getting at. The 1710 was quite a bit lighter, but they could have pretty easily adjusted the CG while they were in the prototype phase. It probably came down to the fact that it was just not feasible in budget or timeline to continue work with the design, considering the much faster P-51 first flew three years prior, and had already been in service for a year by the time the XP-54 first flew.

The XP-54 was beautiful. But I think the concerns about the magnesium frame are over blown. Yes, scraped down magnesium will burn, but the same applies to aluminum and that isn't a whole lot harder to catch on fire. Both have an ignition point below that of av gas or burning ordinance if you are talking shavings, but if you have big chunks they aren't going to burst into flames randomly or even just from some bullet holes. Of course, both will burn as part of a crash. And a garbage engine can lead to that.

The J21 also required SAAB to develop their own ejection seats roughly at the same time as Germany did during WWII

[@larryjacobsen4079]

The first Russian jet fighters looked like piston-engine converted to jets (Mig-9 and Yak-15)

[@kronop8884]

@@larryjacobsen4079 True, Yak-15 (based on the Yak-3 fuselage) and the Swedish Saab 21R were the only two jets to be successfully converted from piston-power to enter production. Mig-9 was a clean sheet design afaik

[@christofferwillenfort4035]

It is very simmilar in apearence to the SAAB j21 (en.wikipedia.org/wiki/SAAB_21) but the SAAB made 400MPH on only 1,455HP. (from a Daimler-Benz DB 605B )

I would love to see you make a video on this silvanskii IS

[@skyislands8887]

What a beautiful looking craft and magnificently presented., thank you Well noted on several occasions.... just one problem... another problem arose....etc When magnesium was mentioned my first thaught was a flying incendiary. The designers were ahead of their time but seemed to extend beyond what was possible to build on the day, rather ooking at what could a future possibly, e.g the pressurised cockpit. What would have transpired if jet engines were available for this plane?

[@jeffbrinkerhoff5121]

"Swoose" was a popular song of the Era about a creature that was a cross between a swan and a goose. Additionally the actress Swoosie Kurtz is the daughter of heroic ww2 aviator Frank Kurtz who had a hybrid plane cobbled together from a couple wrecks to get back in action. That plane was very successful and as the progeny of 2 different designs was dubbed the "Swoose" like the bird in the song.

Magnesium alloys are widely used in jet engines, in the structures of military and civilian helicopters, and in hundreds of auto components, without flammability issues

[@hatman4818]

... Because theyre alloys. I dont think mettalurgy was quite there yet in WW2.

[@kyle857]

​@@hatman4818 It was. The plane wasn't made of straight magnesium.

[@finncarlbomholtsrensen1188]

In Germany the very/too advanced Heinkel 177 bomber also had two engines coupled along the propeller axle in each wing and when "Dicke Herman", Herman Göring saw the engine, he became furious, as he knew they would be very difficult to maintain in the field. It also had a very advanced cooling system below the plates on the wings, making the plates flex in the cold, high altitudes. But it was faster than the fighters, so it didn't need much protective armament by that.

[@mycroft1905]

Most interesting. TFP. Is that a Vengeance in the background at 12:00? There are similarities between the wing forms of the two designs; more pronounced on the XP-54.

[@herbertshallcross9775]

It might be interesting to know more about results and even comments from it's flight testing. Designers keep "seeing" theoretical potential for higher efficiencies of pusher propellors, but few pushers have become successful aircraft. The clean air the flight surfaces and fuselage skins are supposed to benefit from because the propellor isn't trashing the air seems to be largely offset by the propellor not seeing clean air entering the prop disk. Many pushers (notably the Beech Starship) are god-awful noisy because of the propellor cutting through the different pressure areas from the lifting surfaces. and generating that noise has to have an impact on efficiency. The Molt Taylor Mini-Imp and the Lesher Teal seem to have made pushers work, but even though plans were offered tor the Mini-Imp, I don't think many were constructed.

"Tail sitters and the Allison YT40". "The Westland Whirlwind". "Early G.E. turbojets". Whirlwind (and a lot of others) had more problems than just its engines, but an undeveloped or "bad" engine design kills more aircraft proposals than the opposite.

[@stevenborham1584]

Elegant as a Girraf, no doubt the first of the designs that lead to monstrosities like that of the Douglas egg-beater powered flying barns and Hugh's twin boom job that would have impressed the designers of the Dreamliner.

[@stevenborham1584]

Sorry I meant Virgin Mothership, not Dreamliner.

[@ronaldharris6569]

That horizontal stabilizer was going to have issues from turbulent air coming from the prop

[@allangibson2408]

That is actually a plus - think vectored thrust. It just needs to be exceptionally stiff. Conversion to jet power would have been “interesting”.

[@ronaldharris6569]

@@allangibson2408 it was probably the reason they had flight worthy issues other than the experimental engine. I can imagine what a bad idea it would be to have magnesium tailbooms near the jet wash from a gas turbine engine

[@allangibson2408]

@@ronaldharris6569 The booms wouldn’t be a problem, the horizontal stabiliser would however definitely need moving out of the jet wash…

I wonder if Vought use the ideas of the inverted gull wing and installing the supercharger/turbochargers radiators being in the wing root facing forward on the F4U Corsair

[@AudieHolland]

*NOTE:* Bailing out of any plane from low altitude was possible but it meant certain death in all cases. So it wasn't just the primitive ejection mechanism of this fighter that was prone to causing death at low altitudes. It wasn't untill 1961 the famous company Martin Baker developed the even more famous 'zero-zero' Mk. 12 ejection seat. It could succesfully launch a pilot from zero feet altitude at a speed of zero knots. And the pilot would most likely also survive. Previously, if a pilot had to get out fast while the plane was still on the runway, he would have to open the cockpit, get out of his seat and climb down before the plane caught fire/exploded. With the 'zero-zero' seat, the pilot could eject, then be shot upwards to a survivable altitude till his seat auto disconnected and his chute was deployed automatically. So even if the pilot lost consciousness after initiating the ejection procedure, survival chances were still excellent.

[@duneydan7993]

The Rolls Royce R Series engines designed in 1929 and 2800 hp. They were used to win the Schneider Trophy outright. The development of RR V12's went on through Spitfires, Hurricanes, Lancasters, Shackletons and even the P41, etc. Not bad for a piddling little island stuck in the North Sea. My father said if you went through the gate (an emergency only throttle setting) all hell broke loose.

[@cal-native]

Gorgeous, innovative design, ahead of its time. I kept cringing as they went through engine choices, knowing that none were successful. Was wondering to myself how it would have performed with some of the early jet engines.

[@louisavondart9178]

Yep, a Goblin 3 engine would have made it comparable to a Venom fighter is my guess.

Look into the idea of wingless aircraft like the Lippish Aeodyne and the Flying Flapjack.

[@alessiodecarolis]

Without all these problems perhaps it could've worked, don't understand why using magnesium for the build, the downward ejection seat was really idiotic (oh wait, the early F104s), the design was similar to the SAAB 21, with the difference that it worked. So well that it was modified in the SAAB 21R, the first swedish jet fighter, and it had an ejection seat from the early versions. Perhaps also the P54 could've been modified with a jet engine.
