本研究提出了一种创新的集成热防护系统（ITPS）概念，将形状稳定的复合相变材料融入波纹芯ITPS结构中，以增强热防护性能。首先，通过隔热实验和数值瞬态传热分析研究了其传热特性。然后，通过顺序热-力耦合方法对其承载能力进行了研究。最后，在建立的数值分析模型的基础上，建立了全局优化程序，验证了该结构在实际再入条件下的优势。实验结果与仿真结果吻合较好。实验结果表明，与传统的ITPS相比，其最大底面温度降低了18.46%。优化结果表明，与传统ITPS相比，所提出的ITPS减重14.32%，减厚46.09%，有利于实现整车设计的轻量化和高结构效率。
In this study, an innovative integrated thermal protection system (ITPS) concept that incorporates shaped-stabilized composite phase change material into corrugated core ITPS structure is proposed to strengthen the thermal protection performance. First, the heat transfer characteristics were investigated through both the heat insulation experiment and numerical transient heat transfer analysis. Then, the load bearing capacity is researched through the sequential thermal-mechanical coupling method. Finally, based on the established numerical analysis models, a global optimization procedure was established to verify the advantages of the proposed structure under the actual reentry conditions. Experimental and simulation results show agreement with each other on the thermal insulation ability. And a reduction of 18.46% in maximum bottom face sheet temperature was observed in the experiments when compared with the traditional ITPS. Moreover, the optimization results showed that the proposed ITPS achieved a reduction of 14.32% in weight and a decrease of 46.09% in thickness with respect to the traditional ITPS, which thereby contributes to the lightweight and high structural efficiency of the vehicle design.
