ABSTRACT:
A system to assist flap actuation of a convergent-divergent exhaust nozzle to overcome the high air loads on the flaps, so that the nozzle flaps can be properly positioned by the actuators. The structural members of the system are operatively associated with a controlled, air-pressurized, cavity positioned in the exhaust nozzle section. Pressurized air from the cavity acts against the flaps, and helps to overcome the load required to move them. The system is useful in any exhaust nozzle, and most particularly where the exhaust nozzle is two-dimensional, i.e., rectangularly shaped.
