Abstract: A wing assembly and method for operating the wing assembly, the assembly having a main wing and high-lift body movably coupled to the leading edge of the main wing, the coupling achieved by a driving device, an adjusting lever arrangement having a first main wing lever coupled to the main wing formed between a first adjusting lever pivot joint and the high-lift body as well as a second main wing lever coupled to the main wing so as to form an effective lever arm between a second adjusting lever pivot joint and a first adjusting lever pivot joint, and at least one adjusting lever non-rotatably coupled to the high-lift body, the high-lift body being movable between an initial position and a maximally adjusted position with respect to the initial position, at least one guide mechanism aiding movement of the high-lift body.

Abstract: An airfoil and method with a main wing and high-lift body on the leading edge of the main wing movable between an initial adjusting position and a maximally changed adjusting position referred to the initial adjusting position, with at least one guide mechanism. The high-lift body is movably coupled to the main wing and with a driving device. An adjusting lever arrangement and adjusting lever are coupled to the high-lift body. A first main wing lever coupled to the main wing is formed between the first adjusting lever pivot joint and the high-lift body, and a second main wing lever is coupled to the main wing such that an effective lever arm is formed between a second adjusting lever pivot joint and a first adjusting lever pivot joint.
