- What really allows airplanes to fly? 14 answers
I learned, in grade school, that lift was generated via the particles on either side of the wing having to reach the other end at the same time. Looking back, that indeed has no physicality to it. So what is the real explanation of how lift is generated? I've found references to Navier Stokes, but I don't know what that is. What is the best way to learn, from the ground up, why some curved object would generate a definite change in pressure? I can see the results, and I know that there is a pressure difference, but why is that pressure difference, and the two different velocities generated?
