Abstract: An improved target-type thrust reverser for use with an aircraft jet engine. Jet engines typically are housed in a nacelle and the engine terminates with an exhaust nozzle. The thrust reverser includes an upper door having a shape of a segment of a hollow frusto-conical member with an inner and outer surface, opposed longitudinal edges that taper towards each other, a forward semi-circular edge and a rearward semi-circular edge. The lower door is substantially identical. A pair of linkage arms pivotally support each of the upper and lower doors so that the doors are translatable between stowed and actuated positions. When in the stowed positions, the exterior surface of the doors form a part of the exterior surface of the engine nacelle. When in the actuated position, the doors are positioned rearwardly of the engine exhaust nozzle with their rearward edges in abutment.
