ABSTRACT:
A pressurization system for a positive explosion tank in a monopropellant fuel powered system having a solid propellant device used to provide the gas pressure in the positive expulsion tank. A relief valve is provided between the solid propellant device and the positive expulsion tank to prevent over pressurization of the tank. A deflector shield is provided in the inlet of the positive expulsion tank to protect the tank bladder from direct impingement of the hot gases from the solid propellant device. With sodium azide used as the solid propellant, a device is provided in the positive expulsion tank to permit self flushing of the monopropellant catalyst pack.
