Note (General): In a previous report, we compared scramjet engine characteristics of different propellant feed cycles, and discussed engine performances. In this study, we examined a hydrogen fueled airframe-integrated scramjet, considered the cooling of the airframe as well as the engine, and analyzed how engine characteristics depend on such parameters as flight Mach number, flight dynamic pressure, engine wall temperature, and engine scale. We found that the coolant required for the airframe is about 20％ of the total coolant. We derived simple equations which correlate fuel flow rate, engine overall thrust and specific impulse with those parameters. As for the airframe cooling, we proposed a new cycle in which the airframe cooling system has its own coolant feed system and does not depend on the engine operating conditions.
