ABSTRACT:
The C/D axisymmetrical exhaust nozzle for a gas turbine engine is designed to fit on the engine and STOVL aircraft and includes a combined load balancing piston/synchronization ring that is discretely attached to a fulcrum link for positioning the convergent and divergent flaps of the nozzle. The balancing piston which is motivated by engine's fan discharge air permits the use of smaller hydraulic actuators and the quantity of fuel used as the hydraulic medium required to meet the power needs is significantly reduced.
