If Bernoulli is correct, why do they put wing designs in a wave tank to test them!?!?!
Actually, using a wave tank is wrong anyways, because while you can compress air, but you cannot compress water.

Just think if the surface vessel designers, designing boat hulls and trim tabs, would meet an aircraft wing designer, I bet the bottom of the wings would look much different (and work much better)

Lets face it, Newton is correct, the aircraft planes through the air, just like a boat on the surface of the water, and the waveform off the bottom of each is very much the same.

While the wave from the surface vessel tends to roll outward, the aircraft wing wake turbulence would as well, if the component from the top of the wing did not cause a rollup at the intersection of the influences.

Boeing is testing the 777-B on Puget Sound right now..
