摘要：A housing is mounted to the convergent portion of a convergent- divergentthrust nozzle for rockets via legs that space the housing from the nozzle so that it willnot obstruct the flow of propulsive gases therethrough. A cavity in the housing holds asecondary nozzle member having a throat that is smaller in diameter than that of theprimary nozzle. An electrically actuated, gas producing device in the housing forces thesecondary nozzle member out of its cavity on command and seats it against theconvergent portion of the primary nozzle. Simultaneously, ports in the housing areopened to the propulsive gases of the rocket, this forces a plug, that seals the secondarynozzle during storage, out through the primary nozzle.
Some embodiments of the invention also provide for attaching a rocket igniter to thehousing, so that the electrical wiring to the igniter can pass through the same ducts andholes as the wiring to the gas producing device for deploying the secondary nozzle.
