A pneumatic power supply for use in powering servo controls and actuators s 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.

Heater for ultra high pressure compressed gas

An improved bi-propellant injection system for a liquid propellant gun inding a valve which is positively opened at the start of the injection of the fuel and oxidizer into the gun chamber and held at a predetermined displacement to provide a constant size propellant orifice throughout the fuel and oxidizer injection cycle.
