A high-lift system is described for an aircraft, having a high-lift flap (2) which is arranged on the mainplane (1) of the aircraft, and which can pivot at one or more rotation points (3; 10, 11, 12) on the wing (1) or on a carriage (9) or a lever (13) which is coupled to the wing. The flap (2) can be moved by means of an actuating drive between a retracted position (I), in which the flap (2) complements the wing profile essentially continuously, and a plurality of extended positions (II, III), in which a slot (4) of the given width is formed between the wing (1) and the flap (2), and the flap (2) is positioned at a predetermined angle with respect to the wing profile. The rotation point (3; 10, 11, 12), about which the flap (2) can be pivoted is arranged in a variable position with respect to the wing (1) or the carriage (9) or lever (13) which is coupled to the wing, so that the aerodynamics of the overall profile are variable.

L'invention concerne un système hypersustentateur pour un aéronef, comprenant un volet hypersustentateur (2) monté sur un plan principal (1) de l'aéronef et capable de pivoter autour d'un ou de plusieurs points de rotation (3 ; 10, 11, 12) sur une aile (1) ou sur un chariot (9) ou un levier (13) couplé à l'aile. Le volet (2) peut être mû au moyen d'un dispositif d'actionnement entre une position rentrée (I), dans laquelle il complète le profil de l'aile de façon essentiellement continue, et une pluralité de positions sorties (II, III), dans lesquelles une fente (4) d'une largeur donnée se forme entre l'aile (1) et le volet (2), celui-ci formant un angle prédéterminé par rapport au profil de l'aile. Le point de rotation (3; 10, 11, 12) autour duquel le volet (2) peut pivoter occupe une position variable par rapport à l'aile (1) ou le chariot (9) ou le levier (13) couplé à l'aile, de façon à donner au profil global des caractéristiques aérodynamiques variables.
