Abstract:
A thrust-reverser for a bypass turbojet-engine with an external cowling, comprising:at least one hollow door (3) having an inner duct (10), an upstream end, a downstream end and an outer panel (4);a displacement control system (19) which pivots the door (3) about a door pivot (9) between a closed position in a forward-thrust mode and an open position in a reverse-thrust mode, the door (3) constituting part of the external cowling when in the closed position, the upstream end of the door (3) extending inwardly from the external cowling so as to constitute a flow-deflecting means with at least a first portion of a deflected flow following the inner duct (10) when in the reverse-thrust mode; andat least one movable deflecting cascade (23) including a plurality of vanes (25) and hinging about a cascade pivot (24, 35), at least an upstream portion of the cascade (23) forming a deflector (26) which projects beyond an outer surface of the outer panel (4) of the door (3) when the door is in the open position so that a second portion of the deflected flow deflecting outside the door (3) avoids interference with the first portion of the deflected flow which is exhausted from the inner duct (10) of the door (3).
