Abstract

Dispositif de contrôle du profil d’une aile d’aéronef, aile d’aéronef à profil variable intégrant au moins un tel dispositif et aéronef comprenant au moins une telle aile L'invention a pour objet un dispositif de contrôle du profil d’une aile d’aéronef comprenant : une structure fixe (34),au moins une peau semi-rigide (28) formant au moins une partie d’une paroi supérieure ou inférieure (16) de l’aile,au moins un système de déplacement (36) positionné entre la structure fixe (34) et la peau semi-rigide (28) et configuré pour déplacer la peau semi-rigide (28) par rapport à la structure fixe (34) de manière à provoquer un rapprochement de la structure fixe (34) et de la peau semi-rigide (28) et/ou à écarter la structure fixe (34) et la peau semi-rigide (28). Ce dispositif de contrôle de profil permet de faire varier le profil de l’aile et de modifier ainsi sa portance sans avoir besoin de modifier son incidence. L’invention a également pour objet une aile d’aéronef comportant au moins un tel dispositif ainsi qu’un aéronef comprenant une telle aile. Figure 12Device for controlling the profile of an aircraft wing, variable profile aircraft wing integrating at least one such device and aircraft comprising at least one such wing The subject of the invention is a device for controlling the profile of an aircraft comprising: a fixed structure (34), at least one semi-rigid skin (28) forming at least part of an upper or lower wall (16) of the wing, at least one displacement system (36 ) positioned between the fixed structure (34) and the semi-rigid skin (28) and configured to move the semi-rigid skin (28) relative to the fixed structure (34) so as to bring the fixed structure ( 34) and the semi-rigid skin (28) and/or separating the fixed structure (34) and the semi-rigid skin (28). This profile control device makes it possible to vary the profile of the wing and thus modify its lift without having to modify its angle of attack. The invention also relates to an aircraft wing comprising at least one such device as well as an aircraft comprising such a wing. Picture 12
