Title (EN) NACELLE FOR A TURBOJET ENGINE COMPRISING A CASCADE-TYPE THRUST REVERSER
(FR) NACELLE POUR TURBOREACTEUR COMPORTANT UN INVERSEUR DE POUSSEE A GRILLES
Abstract:
(EN) The invention relates to a thrust reverser for a turbojet engine nacelle, comprising thrust reversal cascade vanes (10) arranged about an annular flow duct comprising a stationary front casing (2); at least one movable cover (4) moving backwards into a thrust reversal open position; and tilting flaps (14, 16) connected by rear pivots to the movable cover (4), which, in an open position, tilt and thereby at least partially close the annular flow duct, this reverser being characterised in that the cascade vanes (10) move backwards with the movable cover (4), in that, in the closed position, the tilting flaps (14, 16) and the cascade vanes (10) are arranged outside the stationary casing (2), and in that each tilting flap (14, 16) is connected to the stationary casing (2) by slides (36, 44) which cause it to tilt when the movable cover (4) moves backwards.
(FR) L'invention a pour objet un inverseur de poussée pour une nacelle de turboréacteur, comportant des grilles d'inversion de poussée (10) disposées autour d'une veine annulaire comprenant un carter avant fixe (2), comportant au moins un capot mobile (4) reculant vers l'arrière dans une position ouverte d'inversion de poussée, et comportant des volets basculants (14, 16) reliés par des pivots arrière au capot mobile (4), qui basculent en fermant au moins en partie la veine annulaire en position ouverte, cet inverseur étant remarquable en ce que les grilles (10) reculent avec le capot mobile (4), en ce que dans la position fermée les volets basculants (14, 16) et les grilles (10) sont disposés à l'extérieur du carter fixe (2), et en ce que chaque volet basculant (14, 16) est relié au carter fixe (2) par des glissières (36, 44) qui le font basculer lors du recul du capot mobile (4).
