Abstract

L'invention porte sur un dispositif pour constituer la portion extrême d'un profil aérodynamique d'aéronef. Le dispositif comporte un profilé (1) qui comprend, en un ensemble adapté à être rapporté d'un seul tenant audit profil pour former un bord de fuite (BF) une chambre de soufflage (2) et une buse (3) permettant la mise en communication fluidique entre la chambre de soufflage (2) et une surface externe du profilé (1). Par soufflage d'air par la ou les buses (3), les perturbations aérodynamiques dans le sillage du profil sont réduites. Le dispositif permet ainsi une intégration compacte et facile à mettre en œuvre d'un dispositif de soufflage, à proximité immédiate du bord de fuite (BF). L'invention porte aussi sur un ensemble comportant un tel dispositif. Dans certains modes de réalisation, le profil est doté d'une écope pour écoper tout ou partie de la couche à sa surface, pouvant être également disposé très en arrière du profil.
