摘　　要：本文为解决高超声速飞行器长时间飞行过程中面临的气动加热与设备发热问题,对高超声速飞行器综合热管理系统展开了研究。 设计了一种飞行器综合热管理系统,包含热控子系统与热防护子系统,利用Matlab / Simulink 对系统展开了动态仿真,基于[火积]分析对系统中换热器面积进行优化。 得到热控和热防护两个子系统的最优储冷材料质量分别为11. 2 kg 和 64 kg,在系统中添加流量调节模块,使系统在28% 的时间段内处于低泵功状态运行,优化后热控子系统的换热器减重约 11. 5%,热防护子系统的换热器减重约24. 1%。In order to solve the problems of aerodynamic heating and equipment heating faced by hypersonic vehicle when it’s in the long-term mission,the integrated thermal management system of hypersonic vehicle is studied in this paper.An integrated thermal management system of hypersonic vehicle was proposed,including thermal control subsystem and thermal protection subsystem.The transient simulation of the system was established by Matlab/Simulink,based on the entransy analysis,the heat exchanger area in the system was optimized.The optimal cold storage material masses of thermal control subsystem and thermal protection subsystem were found,which are 11.2kg and 64kg respectively.The flow regulation module was added to realize the thermal protection subsystem operate in low pumping state in 28%of the time.Compared with the design value,the weight of heat exchanger of thermal control subsystem was reduced by 11.5%,and that of heat exchanger of thermal protection subsystem was reduced by 24.1%.
