Abstract

L'invention porte sur un profil aérodynamique d'aéronef comportant un profilé (1) constituant un bord d'attaque (BA) du profil aérodynamique. Le profilé (1) comporte une ouverture au niveau dudit bord d'attaque (BA) permettant l'entrée d'air dans l'épaisseur dudit profil aérodynamique, une sortie d'air, et des moyens de guidage conformés pour guider l'air vers la sortie d'air. L'ouverture au bord d'attaque permet de faire entrer de l'air dans l'épaisseur du profil, limitant les turbulences aérodynamiques au niveau dudit bord d'attaque. L'invention porte également sur un mât portant un groupe propulseur d'aéronef et comportant un tel profil aérodynamique. L'invention porte enfin sur un aéronef équipé d'un tel profil.
