Reduce the curve at the top side, sharpen the leading edge, and flatten out the bottom side, and you've got yourself a high-speed wing.

This is a wing section from the Dassault Rafaele. Also transonic buffeting is common on every single airliner, at ~400mph the wings on a craft and the upper section of the engine can easily see sonic shockwaves form.

Alot of energy to tell you your elementary wing shape is shit.

I would also like to note, it's pretty impressive that turbulence was modelled like that from just equations. Very cool!

Here's the kicker, the computer simulations showed us something that we didn't even anticipate and it checks out in reality. You see those shock waves? Those are sound waves compressing, and when the frequency of the peaks is around 6-10, there's almost NO buffeting whatsoever. The big instabilities happen when there's only 1-2 peaks.

That means the 6-10hz range is the resonant frequency for the instabilities. So if the wing fluttered at 6-10hz during transonic flight there would be no buffeting as the low amplitude waves would be cancelled out by the resonant frequency of the structure.

This is actually from the canard on the Rafaele.

Like I said, it's a shitty wing shape.

It could be better, you should work for them and show them the way.
