Abstract

L'invention concerne un volet pour système de sustentation opérant par soufflage sur surface d'extrados. Le volet 34 est placé sur le bord de fuite de l'aile 14, en arrière du réacteur correspondant 26 et il comporte une surface d'extrados 38 qui est incurvée de manière que son rayon de courbure augmente, dans la direction de corde, depuis la partie incurvée avant jusqu'au bord de fuite; chaque volet est déplacé d'une position de rangement dans l'aile jusque dans une position de déploiement complet où la surface d'extrados du volet forme un prolongement continu de la partie arrière fixe de la surface d'extrados de l'aile, des générateurs de tourbillons 35 étant placés en avant du volet pour produire des tourbillons servant à réduire le moment de tangage longitudinal quand le volet se trouve dans sa position de déploiement. Application aux avions à décollage et atterissage court.
