ABSTRACT:
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.
