Compact pressure balanced nozzle

摘要

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 30 that is attached to a fulcrum link 32 for positioning the convergent and divergent flaps 34,36 of the nozzle. The balancing piston 30 which is motivated by engine's fan discharge air permits the use of smaller hydraulic actuators 46 and the quantity of fuel used as the hydraulic medium required to meet the power needs is significantly reduced. <IMAGE>
