Abstract: A variable area exhaust nozzle is provided with seals between adjacent flaps to minimize flow loss therebetween when the flaps are modulated between minimum and maximum nozzle area positions. The overlapping seals is linked to the adjacent flaps by means of a bellcrank which operates to maintain the seal in a centered position between the flaps. A circumferential track is provided on the flaps to stabilize the seal in the axial direction.

Abstract: A translating flap convergent/divergent-aircraft engine thrust nozzle and integrated thrust reverser including a cascade for reversing the flow of engine exhaust, an inner exhaust duct-translating segment and an outer cowl normally enclosing the cascade therebetween; a series of blocker doors positioned in a normal stowed, inactive relation in the aft end portion of the thrust nozzle; main, hydraulic actuators are interconnected with and operable to simultaneously translate the translating segment and cowl to open a reverse-exhaust flow path through the cascade; and a cam-operated device interconnected between the translating segment and the blocker doors to automatically reposition the blocker doors to an active position blocking the engine exhaust path through the thrust nozzle in concert with the translation of the translating segment and cowl to their reverse flow-producing positions.
