Abstract
In a previous report, scramjet engine characteristics of different propellant-fed cycles were compared and engine performances were discussed. In this study, the cooling requirement of a hydrogen-fueled airframe-integrated scramjet engine as well as an airframe was examined, and effects of various parameters including flight Mach number, flight dynamic pressure, engine wall temperature, and engine scale, on the engine characteristics were analyzed. The coolant required for the airframe was about 20% of the total coolant. Simple equations that correlate coolant flow rate with those parameters were derived.
