  • Patent number: 5042745
    Abstract: A tilt ramp swept edge nozzle for vectoring exhaust gases from an engine mounted in an aircraft has a pair of flaps pivotally affixed to the aircraft in the area of the output end of the engine tailpipe. The flaps are in spaced relation to each other, aligned with the trailing edge of the airfoil of the aircraft and are movable to positions substantially parallel to each other and to positions substantially non-parallel to each other. An actuating system coupled to the flaps moves same relative to each other thereby to maintain a substantially constant effective throat area in the nozzle and providing an increasing nozzle aspect ratio and variable thrust direction during transition from forward to aft throat position of the nozzle.
