A pneumatic power supply for use in powering servo controls and actuators has a filament wound composite and aluminum ultra-high pressure vessel containing helium within which there is mounted an internal pyrotechnic heat generating element to provide thermal energy to the system. The heater compensates for adiabatic cooling of the gas inventory during blow down, i.e., during delivery of high pressure gas to power pneumatic servo controls and actuators in missiles. At the beginning of the blowdown, the heater element burns at a predetermined rate which adds heat to the compressed gas so that the gas temperature remains relatively constant, effectively increasing run time. The pressurized gas is delivered by means of a pressure regulator from the pressure vessel to the delivery system for use in the pneumatic control system.
