Abstract : This patent describes 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 o 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. (Author)
