Abstract

Carter d’entrée (10) pour une turbomachine d’aéronef, comportant une rangée annulaire d’aubes (16) s’étendant sensiblement radialement par rapport à un axe du carter (18), chacune de ces aubes comportant un bras fixe (22) amont et un volet mobile (24) aval, le volet mobile comportant un intrados (38) et un extrados (40) et étant monté pivotant autour d’un axe sensiblement radial et déplaçable entre une première position dans laquelle il s’étend dans le prolongement axial du bras fixe et une seconde position dans laquelle il est incliné par rapport au bras fixe, le carter d’entrée comportant en outre un système d’étanchéité (52) situé entre le bras fixe et le volet mobile de chaque aube et comportant une première languette (56) assurant une étanchéité entre le bras fixe et l’extrados du volet mobile, sur sensiblement toute son étendue radiale, caractérisé en ce que le système d’étanchéité comprend une seconde languette (54) assurant une étanchéité entre le bras fixe et l’intrados du volet mobile, sur sensiblement toute son étendue radiale, et en ce que des passages (58, 62) d’air de dégivrage sont prévus entre la seconde languette et le volet mobile, ou dans le volet mobile, pour l’écoulement d’un flux d’air de dégivrage depuis le bras fixe sur l’intrados du volet mobile.
