就高超声速飞行器防热与热控问题，从“相变蓄热材料充当辅助冷源”思路出发，结合不同飞行器的 飞行特点，提出了５ 种热控系统方案，即空气循环热控方案、蒸发循环热控方案、液体冷却回路方案、开式蒸发 冷却热控方案、直接式相变蓄热冷却方案；指出了选择合适相变蓄热材料及相变蓄热封装设计是其中的关键 技术，并结合航空航天领域相关技术进行了探讨与分析

To solve the problem of thermal barrier is one of the key technologies that restrict the development of hypersonic vehicles. Starting from the point that phase change materials could be used as additional heat sink, five thermal control system concepts using phase change materials are put forward based on characteristic of different vehicles. They are air cycle system, vapor cycle system, liquid loop system, open evaporation cooling system and direct phase change materials heat storage system. The key technologies for the concepts are selection of appropriate phase change materials and encapsulation design of the materials, which are discussed on the background of aeronautics and astronautics.
