ABSTRACT:
A turbojet-engine thrust reverser comprising at least one pivoting hollow door (3) which in the forward-thrust mode is integrated into the external cowling and which in the thrust-reversal mode constitutes a flow-deflecting obstacle by forming a scoop. A movable deflecting cascade (23) comprising vanes is combined with each door (3). The movable cascade (23) hinges about a pivot (24) and comprises at least one upstream portion forming a deflector (26) projecting, in the thrust-reversal mode of the door (3), beyond the outer surface of an outer panel (4) of this door (3) in such manner that any interference between the exhaust flow from the door (3) and the flow deflected to the outside of the door (3) is avoided.
