Abstract
L'invention concerne un inverseur de poussée comprenant : - une structure fixe (43), - un capot d'inversion de poussée (42) mobile en translation entre une position de jet direct et une position de jet inversé, - une structure de déviation (6) d'air éjecté du turboréacteur en position de jet inversé, La structure de déviation d'air est formée par une membrane souple (6) prise entre une première armature (60) et une deuxième armature (61), la première armature (60) étant solidaire du capot d'inversion de poussée mobile (42) de l'inverseur, la deuxième armature (61) étant guidée en rotation par deux liaisons articulées (6C), la deuxième armature (61) étant solidaire d'un mécanisme de déploiement (44) relié au capot d'inversion de poussée (42) mobile pour permettre le déploiement de la membrane souple (6) entre une position de jet direct et une position de jet inversé pour guider, la deuxième armature étant guidée en rotation par les deux liaisons articulées (6C) selon un même axe de pivotement (O).The invention relates to a thrust reverser comprising: - a fixed structure (43), - a thrust reverser cowl (42) movable in translation between a direct jet position and a reverse jet position, - a deflection structure (6) air ejected from the turbojet in reverse jet position, The air deflection structure is formed by a flexible membrane (6) taken between a first frame (60) and a second frame (61), the first frame (60) being integral with the movable thrust reverser cowl (42) of the reverser, the second frame (61) being guided in rotation by two articulated connections (6C), the second frame (61) being integral with a deployment mechanism (44) connected to the thrust reverser cover (42) movable to allow deployment of the flexible membrane (6) between a direct jet position and a reverse jet position for guiding, the second frame being guided in rotation by the two articulated links (6C) according to the same pivot axis ment (O).
