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.
