Variable thrust nozzle system

摘要

A variable thrust nozzle system comprises a housing, a pair of nozzle skirts attached to the outer surface of the housing so as to open in opposite directions, respectively, a pair of nozzle plugs disposed in the pair of nozzle skirts so as to define a nozzle throat between the outer surface of each nozzle plug and the inner surface of the corresponding nozzle skirt, a shaft supported for sliding in the housing and having opposite ends connected to the nozzle plugs, respectively, and an actuator linked to the shaft to drive the shaft for sliding motions to vary the sectional areas of the nozzle throats. <IMAGE>
