The control system comprises a plurality of nozzles pointing in different directions, a plurality of gas generators, and pipework connecting the gas generators to the nozzles via gates for allowing or preventing gas being ejected therethrough. Each gas generator is fitted with a shutter disposed in an outlet passage connecting the generator to the pipework, the shutter having a closed position in which it closes the outlet passage by bearing against a seat formed in the passage and against which it is pressed when the generator is not ignited so as to isolate the gas generator in sealed manner from gas contained in the pipework and coming from other generators, the shutter being automatically lifted off its seat to move from the closed position to an open position under the effect of the pressure produced in the generator in response to being ignited, thereby enabling control to be performed with gas generators being ignited independently of one another.

System for controlling a space vehicle by gating gas

A device for controlling a spacecraft by gating gas, the device comprising a nozzle, a gas feed duct, a gate having a seat and a plunger interposed between the feed duct and the nozzle, and control means for opening and closing the gate in order to put the feed duct selectively into communication with the nozzle. The seat of the gate is secured to the nozzle and the nozzle is movable such that the gate is opened and closed by displacement of the nozzle, which displacement is driven directly by the hot gas, without calling on an auxiliary fluid.
