Web18 sep. 2024 · The "Venturi" theory is based on the idea that the shape of the aerofoil acts like a Venturi nozzle, which accelerates the flow over the top of the wing. Bernoulli's equation states that a higher velocity produces a lower pressure, so the low pressure over the upper surface of the aerofoil produces the lift. Figure 3 - "Venturi" Theory (NASA ... WebMost of the lift comes from the main wing, and in fact the tail lifts down, so the main wing also has to support that. (That's for a stability reason.) The lift of a wing is roughly proportional to two things: angle of attack, and; airspeed squared; so, the slower an airplane is flying, the more it raises the nose.
