Abstract: A warm gas accumulator system 10 suitable for use in guidance vane-actuator systems of missiles comprising a tank 12 containing a supply of Tridyne gas, which tank 12 includes an internally mounted catalytic bed 26 and an internally mounted heat exchanger 18. A portion of the flow of Tridyne gas being discharged from the tank is first directed through the catalytic bed 26 and heat exchanger 18 for purposes of generating and transferring heat to the remainder of the contained Tridyne gas. Upon completing its circuit, the diverted portion of the flow is then mixed with the undiverted portion of the flow prior to discharge from the tank for pusposes of improving the volumetric flow rate of warm gas accumulator system 10.

Abstract: A gas generator which is structurally and functionally integrated with a fluid heat exchanger. A liquid which is to be heated, vaporized, and used as pressurized gas is introduced into the integrated apparatus where the liquid absorbs heat from the adjacent, but separated, hot gas flow from the gas generator. Unlike the prior art, this integrated gas generator/fluid heat exchanger is useable to pressurize an oxidizer tank of a liquid engine missile.
