在以前的报告中，超燃冲压发动机的不同的推进剂供给循环的特性进行了比较和发动机性能进行了讨论。研究了氢燃料机身一体化超燃冲压发动机及机体的冷却要求，分析了飞行马赫数、飞行动压、发动机壁温和发动机尺寸等参数对发动机性能的影响。机体所需的冷却剂约占总冷却剂的20%。导出了冷却剂流量与这些参数之间的简单关系式。A B B CD Cp 7sp t M m P Q q
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. A B b CD Cp 7sp t M m P Q q
