| 摘 要： | 对各种防热、热控机理基本规律进行了梳理和研究,认为要进一步提高系统性能,需要进行结构、防热、热控一体化设计。基于这种设计思想,提出了一种将航天器防热、热控和结构相结合的“统一热管理的疏导式防热系统”,在传统防热机制的基础上,加入原先主要用于热控的各种热传输机制,进行防热、热控和结构等子系统间热的统一管理。应用这种系统,可提高防热效果,减轻飞行器的结构重量,减轻高热流区材料与结构的耐温负担,有可能实现长时间、超高速大气层机动飞行器的前缘尖化,还可使整个防热层趋于等温,易于热控处理,减小结构热应力。文章还分析了疏导式防热系统的应用前景,并针对几种典型的航天器（尖鼻锥和尖翼前缘的高超声速巡航飞行器、返回式航天器和载人飞船）提出若干适用的疏导式防热系统的方案设想。

| Abstract: | The analysis and research on basic principle and rule of the thermal-protection system(TPS) and thermal-control system(TCS) are made in the paper.It is considered that further performance improvement of the TPS could be achieved by a kind of leading TPS which is the combination of TPS and TCS of spacecraft and the unified heat management within the systems of thermal-protection,thermal control and structure.The application of the leading TPS could lighten the total mass of the spacecraft,reduce the local te... |
