This paper describes some of the design, construction, and test work which was undertaken to develop a helium-to-hydrogen heat exchanger. Hydrogen is a potentially important fuel for certain propulsive and secondary power applications where low molecular weight and high heat of combustion are important. In many possible airborne system applications, hydrogen is stored at cryogenic temperatures and heated in a heat exchanger before being burned to produce energy. If the heat source is one or several items of equipment which require cooling, use of an intermediate heat transfer loop is indicated. A logical intermediate heat transfer fluid is helium, because of the absence of freezing or condensation at liquid-hydrogen temperatures. This is the background for the present work. The problem statement numbers were evolved from an airbreathing engine design study, but the technology is applicable to the presently more interesting nonairbreathing secondary power devices as well.
