    How is it that an airplane can fly?

    Question #69562. Asked by ohlavash. (Aug 10 06 1:56 PM)

    An aircraft flies due to aerodynamic reactions that happen when there is relative motion between air and a wing.

    The amount of air diverted by the wing is proportional to the speed of the wing and the air density. The vertical velocity of the diverted air is proportional to the speed of the wing and the angle of attack. The lift is proportional to the amount of air diverted times the vertical velocity of the air. The power needed for lift is proportional to the lift times the vertical velocity of the air.
