Two dimensional wedge/translating shroud nozzle

摘要

A jet propulsion exhaust nozzle particularly useful in multi- engine installations which provides high internal/external, thrust-minus- drag, performance for transonic cruise or transonic acceleration as well as improved performance at subsonic and supersonic speeds. A two dimensional wedge/translating shroud is provided at the nozzle exit for providing the variable nozzle exit geometry needed to achieve high engine performance over a wide range of throttle power settings.
