Title (EN) AIRCRAFT PROPULSION UNIT
(FR) ENSEMBLE PROPULSIF POUR AERONEF
Abstract:
(EN) The invention relates to a propulsion unit (2) for an aircraft, comprising a turbofan engine (4) comprising an inter-compressor casing (52) which is fixed and is positioned upstream of an inter-channel space (48), a nacelle (6) comprising, downstream, an internal wall (28) which delimits outwardly the inter-channel space and inwardly the flow channel for the bypass flow (32), and an outer wall (30) which is arranged around the internal wall and which delimits outwardly the flow channel for the bypass flow, at least one part of the internal wall being able to move between a maintenance position and a working position, and a thrust reverser (8) comprising a downstream element of the external wall which is able to move in translation between a retracted position and a thrust-reversing position in which it permits the deployment of elements (46) for deflecting the bypass flow in a radial direction, the deployment of the deflecting elements being controlled by guiding rods (50) of which a first end is secured by a first articulated connection (56) to the deflecting elements and a second end is secured by a second articulated connection (54) to the inter-compressor casing (52) of the turbofan engine.
(FR) L'invention concerne un ensemble propulsif (2) pour aéronef, comprenant un turboréacteur (4) à double flux comprenant un carter inter-compresseur (52) fixe et positionné en amont d'un espace inter¬ veines (48), une nacelle (6) comprenant, à l'aval, une paroi interne (28) qui délimite à l'extérieur l'espace inter-veines et à l'intérieur la veine d'écoulement du flux secondaire (32) et une paroi externe (30) disposée autour de la paroi interne et qui délimite à l'extérieur la veine d'écoulement du flux secondaire, au moins une partie de la paroi interne étant apte à se déplacer entre une position de maintenance et une position de travail, et un inverseur de poussée (8) comprenant un élément aval de la paroi externe qui est mobile en translation entre une position rétractée et une position d'inversion de poussée dans laquelle il autorise le déploiement d'éléments de déviation (46) du flux secondaire dans une direction radiale, le déploiement des éléments de déviation étant commandé par des bielles de guidage (50) dont une première extrémité est fixée par une première liaison articulée (56) sur les éléments de déviation et une seconde extrémité est fixée par une seconde liaison articulée (54) sur le carter inter-compresseur (52) du turboréacteur.
