A novel pivoting door thrust reverser which provides a nozzle for the exhaust of a bypass engine that ensures a smooth continuous flow path for the exhaust without leakage around the pivoted upper and lower reverser doors. The upper reverser door is provided with a pair of biased cooperating crescent shaped kicker members that are biased outwardly in a controlled movement when the doors are deployed to deflect the upper portion of the reversed exhaust efflux forwardly in a predetermined direction to avoid interference with the control surfaces of the aircraft. The lower reverser door is provided with pivoted splitter plates that are biased outwardly when the door is deployed to abut and form a unitary splitter element that divides the lower exhaust efflux into two portions that are directed forwardly and away from the inlet of the engine to preclude foreign object damage to the engine. The thrust reverser is lightweight, uses simple, inexpensive mechanisms, and operates in a very efficient manner when deployed as a thrust reverser and when stowed as an exhaust nozzle for the engine.

[ We claim:] [1.] A thrust reverser for use with a turbo- fan type turbojet aircraft engine and comprising:a fixed structure arranged to be secured to the aft end of an engine and having an annular wall to provide a nozzle for the exhaust of the engine, said fixed structure defining an outer air flow surface and an inner air flow surface,upper and lower symmetrical thrust reverser door members having inner and outer air flow surfaces that are flush with said inner and outer air flow surfaces of said fixed structure and having a leading edge and a trailing edge, each of said door members being pivotally attached at the aft end of the fixed structure and adapted to be movable between a stowed non-reversing position and a deployed thrust reversing position, each of said door members being provided with at least two rotatably movable members carried by each door member at its leading edge that are urged inward to a secured position not extending beyond the inner surface when a door member is in a stowed position and which are pivotally biased outwardly to an air flow deflecting position when the associated door member is pivoted to a deployed position to deflect the reversed flow of the engine in a predetermined manner to preclude foreign object damage to the engine from ingestion of objects from a landing field surface being blown forwardly and ingested by the engine and to preclude interference of the reversed air flow with control surfaces of the aircraft.
