Abstract: A system and method provide for storage and supply of a pressurized gas aboard a launch vehicle such as a rocket-powered craft. Certain rocket powered vehicles, require that one or more propellant tanks be pressurized for a continuous supply of propellant to the rocket engines and to maintain tank structural integrity. According to the system described herein, certain heating elements may be employed for controlling the pressure in a gas supply bottle during the outflow of gas from the bottle so as to provide a continuous supply of pressurized gas and to make available of a large percentage of the gas stored in the bottle. Further, the system described herein provides for the storage of helium under densities above that of liquid helium and through use of a heat source, such as rocket engine supplied hot gas, provides a supply of gas such that it can be used for tank pressurization.
