Abstract:
1. Lift flap mechanism for adjusting a lift flap assigned to an airplane wing by means of a driving system, the lift flap mechanism being disposed on at least one of several flap tracks fastened to the airplane wing, the lift flap mechanism, for carrying the load and for the kinematic guidance of the lift flap, comprising a main connection mechanism and a secondary connection mechanism in the form of a guide lever disposed in an articulated manner on the lift flap via a secondary connection joint and on the flap track, which secondary connection mechanism, viewed in the flow direction, is arranged at a distance from the main connection mechanism, wherein the main connection mechanism has a steering lever arrangement with at least one steering lever which has a first steering lever joint, a second steering lever joint and a main connection joint, the at least one steering lever by way of a pendulum coupled to the first steering lever joint being connected with the flap track, and the second steering lever joint being guided such that, by means of a defined angular position of the at least one steering lever, positions of the main connection joint and of the secondary connection joint are unambiguously determined.
