Less wave damage to shorelines as well

tf are you talking about, aeroplanes cant fly upside down and when they do the pilot has to point the stick forward and down (their down) is our up. a flat foil will lift because its angle of attack causes high and low pressure above its how a boat or the vertical fin on a plane will turn. an angle of attack of zero given the foil has a longer distance up top will lift no matter what as faster flowing fluid has less pressure period. Thats what flaps are for on a wing, increase the length of the top side for extra lift. The first explanation was the correct one the rest were bs.

Lol bro. Planes can fly upside down while factoring in the venturi explanation, because the angle of attack changes…

Quem inventou o hidrofolio foi Enrico Forlanini em 1898. Estaunidenses mentirosos como sempre

This is more accurate than a lot of aerodynamic explanations of wing lift. But the "flow turning down implies lift" does very little to explain in detail why it is working. The simple answer is that there is no simple answer. Calculating the lift on a wing requires detailed, piece-by-piece, tracking of the flow in a huge computational fluid dynamics (CFD) calculation. That is why wind tunnel tests are still used to experimentally measure the lift.

How about the upside down plane?
