: The shape and angle of attack of the wing force the oncoming air streams to bend.
The Kutta condition—which determines the actual circulation—is a manifestation of viscous effects, particularly near the trailing edge. Inviscid flow alone cannot explain how a wing generates lift. understanding aerodynamics arguing from the real physics pdf
Parasite drag is the resistance caused by moving a solid object through a fluid medium, unrelated to the production of lift. It divides into three types: : The shape and angle of attack of
