Abstract

Dispositif permettant de réaliser des jeux minima entre les bords d'un profil aérodynamique à calage variable et les parois délimitant le chemin d'écoulement, dans toutes les positions du profil. Il comprend une première paroi 30, orientée axialement, disposée circulairement autour de cet axe, cette paroi délimitant au moins partiellement le chemin d'écoulement et ayant une surface profilée 34, regardant radialement, qui s'étend circulairement et axialement; un profil aérodynamique à calage variable 38, logé dans ce chemin d'écoulement, qu'il traverse, et possédant une face terminale profilée 40 regardant radialement qui se trouve à une certaine distance en face de la surface profilée, ce profil aérodynamique étant capable de tourner dans ce chemin d'écoulement entre une première et une seconde position autour d'un axe de rotation M-M incliné par rapport à l'axe du moteur, l'écartement DELTA entre la face terminale et la surface profilée étant constant au cours de la rotation du profil aérodynamique autour de l'axe de rotation entre la première et la seconde position. Application aux moteurs d'avion.
