Abstract

L’invention concerne un inverseur de poussée pour ensemble propulsif d’aéronef, l’inverseur comprenant une structure fixe (31) et une structure mobile (29) comprenant un capot mobile d’inverseur (33) présentant une paroi radialement interne (52), la structure mobile étant déplaçable en translation par rapport à la structure fixe selon un axe central longitudinal (A1) de l’inverseur, entre une position avancée de poussée directe et une position reculée d’inversion de poussée. Selon l’invention, une membrane (58) d’obturation de la veine secondaire porte un premier joint d’étanchéité (72) s’étendant selon une direction circonférentielle (27) de l’inverseur, en étant en appui contre la structure fixe (31) et contre l’extrémité amont (52a) de la paroi (52) du capot mobile, lorsque la structure mobile (29) occupe sa position avancée de poussée directe. Figure pour l’abrégé : Fig. 7The invention relates to a thrust reverser for an aircraft propulsion unit, the reverser comprising a fixed structure (31) and a mobile structure (29) comprising a mobile reverser cowl (33) having a radially internal wall (52), the mobile structure being movable in translation relative to the fixed structure along a longitudinal central axis (A1) of the reverser, between an advanced direct thrust position and a retracted thrust reversal position. According to the invention, a membrane (58) for closing the secondary vein carries a first seal (72) extending in a circumferential direction (27) of the reverser, bearing against the fixed structure (31) and against the upstream end (52a) of the wall (52) of the mobile cowl, when the mobile structure (29) occupies its advanced direct thrust position. Figure for abstract: Fig. 7
