ABSTRACT:
A thrust reverser for a turbo-fan type turbojet-engine includes hollow, scoop-type pivoting doors (3) which, in the forward-thrust mode, are integrated into the engine and fan cowling and which, in the reversed-thrust mode, constitute scoop type flow deflecting baffles. A movable upstream visor (23), when in the forward-thrust mode, is situated between the upstream edge of the door (3) and the fixed upstream structure (6) covering the downstream structure of the forward frame (8) of the thrust reverser. The control-driven upstream visor (23) pivots about a pivot mounted on the fixed thrust reverser structure and, in the thrust-reversal mode, uncovers the downstream edge of the structure of the forward frame structure (8) and presents an aerodynamic surface to guide the reverse-thrust flow.
