I feel like an important aspect of the plane wasn't discussed in this video, that the oblique wing (60 degrees sweep angle) was never intended to fly transonic. It was flown during research to collect data by flying a real aircraft, rather than wind tunnel tests. The oblique wing design was proposed by Robert.T.Jones, to fly efficiently in both transonic and supersonic speeds. This aircraft, the AD-1, flew at max, 170 knots where the main idea of the design was to fly at supersonic speeds. Any challenges this aircraft came upon were not really a surprise. The idea of the oblique wing design was to fly at 0 degree sweep angle at low speeds and gradually at 60 degrees sweep angle at supersonic speeds. The AD-1 was really a scaled down NASA version of a passenger oblique wing design by Boeing.

@revenevan11 3 года назад

Yeah I wonder if the same modern control mechanisms that made it unnecessary for fighters and the like, could also make it more practically controllable with modern autopilot features, especially on some sort of drone plane. That said the reasons to do so are still pretty few lol. It would be strange to always have to he rolled like that. Could be even more disorienting in IMC if you need to stay rolled to fly level and straight based on the configuration of the wing.

@fastfiddler1625 3 года назад

@@revenevan11 Oh man. At least in IMC you could do something like have the attitude indicator fake wings level and recalibrate based on speed and pivot. Plus, modern fly by wire planes do so much magic behind the scenes to mask control issues, they COULD make it work.

@maniacal_engineer 3 года назад

Airliners do not cruise below critical mach. If you sit in an overwing exit row seat and the angle of the sun is right (morning flight east to west, port side) you can see the shadow of the normal shock on the surface of the wing. The shock is denser=> different index of refraction => a light/ dark band forms on the wing. Airliners cruise with a normal shock on the upper surface of the wing at about 80-90% chord.

@ASJC27 3 года назад

Yes, very disappointing that such a channel spreads misinformation. I left a similar comment about this and about another mistake - the change in frontal area has zero effect on drag (if this was true variable sweep aircraft would sweep back almost immediately after takeoff). It's only affecting wave drag at transonic/supersonic speeds and at subsonic speeds it increases induced drag. That's why the F-14 kept its wings straight until Mach 0.7.

"Airliners cruise just below critical mach number." Its fairly well established that most airliners are cruising slower than they used to in order to save fuel. Were they previously flying above the critical mach number or do they now fly below critical mach number by a larger margin?

Ok, idea: Single pivot, double decker. So in 0° sweep angle would be a normal double decker plane, in sweep mode it would be a X shape wing (top down view) Lots of things to think about with the landing gear, but would be a cool experiment.

@kuroraiko986 3 года назад

As someone with very little understanding of the underlying physics here, the last bit about variable sweep wings moving center of lift backwards as the sweep angle increases made me wonder if anyone has modeled or tested this design: If you had arms spacing the pivot joints away from the fuselage, the wings could take advantage of the simpler mechanism used here, get the advantage of the symmetric tension, and also keep center of lift centered around the pivot arms. I'm not sure what kind of geometry would solve for the variable distance between the inner edge of each wing and the fuselage, but I feel like it could be fun to play with in Kerbal Space Program or something 😃

Most designs don't make it into the military purely because they "don't look cool". Its actually one of the unwritten requirements that several ship and aircraft designers have attested to. Boeing claim that was one of the key issues of the X-32 that the military brass ultimately rejected in favour of the F-35. Granted there are many factors that get taken into account but humans do tend to look more favourably on things that "look right" to them.

The most logical step would be attaching two of these to the sides of a plane, like massive rotors. Would probably not be worth it with the required arms though. I'm a bit surprised that there are no mechanically linked swept wings though. That should help with keeping forces between them symmetrical.

The National Aeronautics and Space Administration is an independent agency of the U.S. federal government responsible for the civilian space program, as well as aeronautics and space research. NASA was established in 1958, succeeding the National Advisory Committee for Aeronautics.

@anthonyboyer9824 3 года назад

Well it seems to me the logical next step would be to have two pairs of centrally mounted wings. One that sweeps forward, the other sweeping rearward. When straight, they would form a single, wide wing. In this way, it would make sense that the advantages of constant center of lift and structural forces are combines with the symmetrical sweep of traditional wing. Having 4 wings, it could be surmised that the wings can be kept shorter to than normal to somewhat offset the additional drag of the extra wings. Besides, a plane with X-shaped wings would look pretty great.

@sdwboss 3 года назад

Hello Mr Engineering. Just heard a mistake in your information. At 3:02, you said "airliners cruise just below critical Mach number". This is not correct. Airliners usually cruise ABOVE their critical Mach number.

What about a cruciform type wing, one similar to a pair of scissors, similar to this but with 2 wings rotating in opposite directions, wouldn’t that follow the advantages of the oblique wing and also avoid its inherent control weirdness

@chrisamies2141 Год назад

The only issue I can think of is that at zero sweep it becomes a very close-together biplane!

@WhiskyCanuck 3 года назад

At some point I remember NASA had a cool modification of an F-111 where the wings can change their curvature, not like regular flaps but resembling a birds wing where the wing can be curled.

@kitnaylor7267 3 года назад

Eh, drag from a wing's frontal area is minimal compared to the vortex drag of the wingtip vortices and fuselage contributions. What changing wing sweep does is change your wing aspect ratio - at lower sweep (and therefore higher aspect ratio) the tip vortices are reduced, minimising drag and maximising lift as less of your wing area is trashed by tip effects. The only reason you want to change the sweep is when you start hitting transonic effects, hence why subsonic racing aircraft all have straight, high aspect ratio wings to minimise vortex drag rather than swept ones to minimise frontal area.
