高超声速飞行器综合热管理系统方案探讨
Discussion on Integrated Environment Control Thermal Management System Concepts for Hypersonic Vehicle
高超声速飞行器是当今世界航空航天领域研究的热点,由于其在飞行中遭受的热环境极其严酷,因 而可靠的综合热管理系统是安全飞行的保证。针对不同飞行任务的高超声速飞行器,分别提出了综合热管理系 统方案;对飞行时间短,飞行速度和高度变化快的飞行器,提出了以液氢燃料为主要热沉、相变蓄热材料为辅 助热沉的热管理方案;对飞行时间长,飞行马赫数高的飞行器,提出了以吸热型碳氢燃料为热沉的热管理方案; 分别探讨了两套方案涉及的关键技术,指出了未来研究工作的方向。
Hypersonic vehicle is nowadays a focus in the field of aeronautics and astronautics. It will encounter with severe aero-heating during hypersonic flight. As a result, a reliable integrated thermal management system is a necessity to ensure flight safety. Concept of integrated thermal management system was put forward respectively,based on the characteristics of hypersonic vehicles with different missions.For vehicle which is characterized by short flight time and quick change of velocity and altitude,a concept of thermal management system which uses liquid唱hydrogen as major heat sink and PCM material as supplementary heat sink was presented. For that with longer flight time and higher Mach number,a concept of thermal management system using endothermic fuels as heat sink was advanced.Key technologies concerning these concepts were discussed, and research focuses in the future were indicated.
