Note (General): In this paper, engine cycles for airframe-integrated scramjets employing hydrogen fuel are analyzed to investigate regenerative engine cooling characteristics, required pump exit pressure, and overall engine thrust. An expander cycle and a gas generator(G.G.) cycle are examined. It is found that the engine can function with either of these cycles. For flights at high Mach numbers, it is found that the hydrogen flow rate required for engine cooling exceeds the stoichiometric flow rate needed for combustion. The specific impulse of the G.G. cycle is lower than that of the expander cycle because oxygen is needed for the gas generator. If advanced refractory material is available for the G.G.cycle engine wall, it is possible to decrease the hydrogen flow rate needed for engine cooling and thus to enlarge the range of engine operation.
