A gas turbine engine (10) includes a translating sleeve (38) disposed within a downstream portion of an outer nacelle (20). A variable area fan exhaust nozzle (30) is defined between the trailing edge (32) of the translating sleeve (38) and a conical core cowl (26) disposed radially inwardly of the outer nacelle (20) and spaced apart therefrom. The translating sleeve (38) translates downstream to cooperate with the decreasing diameter of the core cowl (26) to increase the area of the fan exhaust nozzle (30).
[ We claim:] [1.] A variable area exhaust nozzle for a gas turbine engine having a longitudinally extending axis, comprising:an aerodynamically streamlined outer nacelle having an upstream portion and a downstream portion, the downstream portion including:a thrust reverser having a moveable body and a plurality of blocker doors radially spaced apart from the moveable body, the thrust reverser being positionable at an engaged position and a disengaged position, anda fixed geometry translatable sleeve having a trailing edge aft of the moveable body, the sl...
