Abstract
A device for pressurizing at least one propellant tank feeding the combustion members of a space vehicle, the tank(s) being connected to one or more pipes for feeding said combustion members, and at least one of the propellants being catalytically or thermally decomposable, the device comprising: tapping means placed at the outlet from the decomposable propellant tank to tap a portion of said propellant, drive gas generation means for delivering drive gases, suction means formed by a converging-diverging nozzle connected firstly to the drive gas generation means and secondly to the tapping means to suck decomposable propellant from the tapping means by lowering the pressure of the drive gases to a value that is less than that required for pressurizing the tank(s), and decomposition means placed at the outlet from the suction means for decomposing the sucked propellant into pressurization gas for pressurizing the tank(s).
