Abstract:
The invention pertains to an airfoil (10) with a main wing (12), with at least one high-lift body (14) that is arranged on the leading edge of the main wing (10) such that it can be moved between an initial adjusting position and a maximally changed adjusting position referred to the initial adjusting position, with at least one guide mechanism (16), by means of which the high-lift body (14) is movably coupled to the main wing (12), and with a driving device (50) for realizing adjusting movements of the high-lift body (14), wherein the guide mechanism (16, 26) features: - an adjusting lever arrangement with at least one adjusting lever (21, 41 ), wherein at least one adjusting lever of the adjusting lever arrangement is coupled to the high- lift body (14), - at least one first main wing lever (18, 38) that is coupled to the main wing (12) by means of a first main wing pivot joint (20, 30) and to the at least one adjusting lever (21, 41 ) by means of a first adjusting lever pivot joint (22, 42) such that an effective lever arm is formed between the first adjusting lever pivot joint and the high-lift body (14), - at least one second main wing lever (19, 39) that is coupled to the main wing (12) by means of a second main wing pivot joint (26, 46) and to the at least one adjusting lever (21, 41 ) by means of a second adjusting lever pivot joint (24, 44) such that an effective lever arm is formed between the second adjusting lever pivot joint and the first adjusting lever pivot joint (22, 42), as well as to a method for realizing adjusting movements of a high-lift body (14) relative to a main wing (12).
