ABSTRACT:
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.
