摘要： Control apparatus for a nozzle for a rocket or other vehicle having a combustion chamber with a propellant therein in communication with the nozzle, the nozzle having a throat and a pair of bores extending into the throat The bores may be in opposed or any other suitable relation. A pair of plungers are slidably mounted in the bores and are movable between an open position wherein they are disposed outside of the throat and a closed position wherein they extend into the throat to substantially close it. The plungers have a width or diameter substantially the same as the width or diameter of the throat. Actuator devices are provided for moving the plungers independently of each other to control thrust by controlling the flow of combustion gases through the throat and the pressure in the combustion chamber. The movement of the plungers can also be used for thrust vector control.

摘要： A nozzle for a gas turbine engine is provided which includes an outer casing, a convergent section, a divergent section, an external fairing, and a collapsible seal member. The divergent section has an aft end and a forward end, and the forward end of the divergent section is pivotally attached to the convergent section. The external fairing has an aft end and a forward end. The forward end of the external fairing is pivotally attached to the outer casing and the aft end of the external fairing is pivotally attached to the aft end of the divergent section. The external fairing is disposed radially outside of the divergent section. The collapsible seal member extends between the outer casing and the divergent section, circumferentially around and outside of the divergent section.
