A turbojet-engine thrust reverser comprises a displaceable sub-assembly including two internal clamshells (12) mounted on stationary pivots (18) of a stationary structure (1) and an annular, axially displaceable structure (11). The displaceable structure forms the external, downstream part (13) of a cowling. In the forward-thrust mode, the displaceable structure forms a downstream portion (15) of a radial outer wall of the flow path and forms the entire trailing edge by covering the clamshells (12) such that the clamshells form part of the radial outer wall of the flow path.

[ We claim:] [1.] A turbojet-engine thrust reverser, comprising:a stationary structure defining an upstream part of a cowling of a turbojet engine;an axially displaceable, annular structure located downstream of the stationary structure which forms a downstream external part of the cowling and a downstream part of a radial outer wall bounding a flow path of the turbojet engine, said displaceable structure being affixed to a casing of the turbojet engine;a plurality of stationary pivots supported on the stationary structure;two displaceable, internal clamshells separate from the displaceable structure and which are pivotable on the plurality of pivots to extend into a position in a thrust-reversal mode wholly contained within the outer radial surface of the stationary structure to constitute flow-deflecting baffles by joining edge to edge along a longitudinal turbojet engine axis to provide thrust reversal; anda displacement mechanism supported by the stationary structure which controls displacement of the displaceable structure and the clamshells;wherein, in a forward-thrust mode, the displaceable structure forms the totality of a trailing edge by covering the clamshells such that the clamshells also form part of the radial outer wall of the flow path and in a reverse-thrust mode, the displacement mechanism axially displaces the displacement structure to clear a passageway in the cowling for flow deflected between the stationary structure and an upstream edge of the displaceable structure.
