ABSTRACT:
A convergent/divergent gas turbine engine exhaust nozzle having reverse thrust capability includes a door which blocks a reverse flow outlet port when the nozzle convergent flap is in any forward thrust operating mode. The door is coupled to the convergent nozzle flap such that it opens as the convergent nozzle flap moves to a reverse thrust position and the flap directs the exhaust gases through the reverser outlet. Coupling is accomplished by a cam track connected to the blocker door and a cam track connected to the convergent flap, with a cam follower interconnecting the two cam tracks. As the convergent flap is rotated, the cams and cam follower cause appropriate movement of the blocker door.
