Airfoil lift12/27/2023 The result of the movement of the wing through stationary air is a lift force perpendicular to the motion of the wing, which is greater than the downwards gravitational force on the wing and so keeps the aircraft airborne. The thrust driving the wing forward is provided by an external source, in this case by propellers or jet engines. It is thus the turning of the air flow which creates the lift.Īircraft are kept in the air by the forward thrust of the wings or aerofoils, through the air. ![]() This means that the force of the aerofoil pushing the air downwards, creating the downwash, is accompanied by an equal and opposite force from the air pushing the aerofoil upwards and hence providing the aerodynamic lift. ![]()
