A high- lift system on the wing of an aircraft and a method for its operation are described. High- lift flaps (2) which are arranged on the wing (1) are extended from a retracted position in order to increase the lift, and a slot (3) through which flow passes from the lower face to the upper face of the wing (1) is opened (advanced slat/flap-gap control). According to the invention, the slot (3) through which flow passes is opened independently of the position of the high-lift flap (2). This makes it possible to selectively achieve a better maximum coefficient of lift (CL) or a better lift-to-drag ratio with less noise being produced.
L'invention concerne un système de grande levée sur l'aile d'un avion et un procédé pour son fonctionnement. Des volets de grande levée (2) qui sont disposés sur l'aile (1) sont étendus d'une position rétractée afin d'augmenter la sustentation, et une fente (3) à travers laquelle un écoulement passe de la face inférieure à la face supérieure de l'aile (1) est ouverte (commande d'espace de volet/bec de bord d'attaque avancée). Selon l'invention, la fente (3) à travers laquelle un écoulement passe est ouverte indépendamment de la position du volet de grande levée (2). Ceci rend possible d'obtenir de façon sélective un meilleur coefficient maximal de sustentation (CF) ou un meilleur rapport sustentation-sur-traînée, tout en produisant moins de bruit étant produit.
