中文摘要：

热防护系统是保证飞行器在气动加热环境下不发生过热甚至烧毁的关键系统.随着飞行速度的不断提升,气动力/热与结构件的耦合效应更加显著,需要通过耦合分析方法才能更准确的评估结构安全性和提升热防护系统设计水平.提出了气动力/热与结构耦合的多类分析方法及实现思路,介绍了相关物理场的数值计算方法,并应用建立的耦合分析方法,对典型热防护系统进行了计算分析.热防护系统耦合分析方法的建立,不但为热防护系统评估与设计奠定了良好基础,同时也为新型防热概念及方法的提出奠定了技术基础.

英文摘要：

Thermal protection system is a key system to prevent vehicle overheating and burning.With the continuous increase of flight speed,the coupling relationship between aerodynamic,aerodynamic heating and structure are more notable.In order to accurately assess structural safety,the problem must be analyzed by coupling.Only in this way can the design level of thermal protection system be raised.The coupling analysis methods have been proposed.The numerical methods of related modules are introduced.The typical thermal protection structures are analyzed and calculated by using the coupling analysis methods.This laid a foundation for thermal protection system evaluation and design.
