A jet of air is impelled on to the upper surface (22) of a flap (20) in order to increase its lift. Part of the air in this air jet is drawn, through air intakes (41), from the air stream flowing over an upper surface (11) of the fixed part (10) of the wing, located upstream of the flap. The air jet drawn in by suction by the air intakes (41) is reinforced by a jet of compressed air blown through a passage (30) which opens immediately downstream of the air intakes (41). This creates a combined jet, comprising the air sucked in and the blown jet, which is ejected on to the upper surface (22) of the flap through outlet apertures (44) located on the rear edge of the fixed part of the wing.
Un jet d'air est propulsé sur la surface supérieure (22) d'un volet (20) afin d'augmenter sa portance. Une partie de l'air de ce jet d'air est aspirée, à travers des admissions d'air (41), à partir du flux d'air circulant sur une surface supérieure (11) de la partie fixe (10) de l'aile, située en amont du volet. Le jet d'air aspiré par aspiration par les admissions d'air (41) est renforcé par un jet d'air comprimé soufflé à travers un passage (30) qui s'ouvre immédiatement en aval des admissions d'air (41). Ceci crée un jet combiné, comprenant l'air aspiré et le jet soufflé, qui est éjecté sur la surface supérieure (22) du volet à travers des ouvertures de sortie (44) situées sur le bord arrière de la partie fixe de l'aile.
