ABSTRACT:
Wing parts (20, 21) which influence the lift of aircraft wings (1), especially wings (1) with a cross section and an angle of attack which is suitable for high-speed flight, which parts can be moved out of an aerodynamically inactive servicing position within the aircraft fuselage (30) or out of chambers (40) mounted on the wings (1) into an aerodynamically efficient active position and from the active position back into the servicing position, are assigned to the wings (1). These wing parts (20, 21) in their active position are located on the top (3) and optionally also on the bottom (4) of the wings (1) and are shaped for example such that the wing parts (21) located in their active position on the bottom (4) of the wings (1) jointly with the wing parts (20) located in their active position on the top (3) of the wings (1) increase the lift and optionally at the same time change the angle of attack of the wing.
