摘要

热保护系统，简称TPS，是保护航天器免受再入和发射过程中发生的极端空气动力学加热的层。本文提出了一种集成热防护系统(ITPS)的优化设计。ITPS提供热保护和结构承重能力。利用完全隐式烧蚀和热响应程序(FIAT)进行热化学模拟，以更好地了解系统在航天飞行器极端条件下的热化学行为。同样，进行结构分析以确定所建议的ITPS设计的结构完整性。热化学分析和结构分析表明，所提出的波纹芯夹层结构在衰退、热解和结构完整性方面是可行的。

Thermo-chemical and structural analysis of integrated thermal protection system for a space vehicle

The Thermal Protection System, or TPS, is the layer that shields spacecraft from the extreme aerodynamic heating that occurs during re-entry and launch. We proposed an optimized design of an Integrated Thermal Protection System (ITPS) in this paper. An ITPS provides thermal protection as well as structural load-bearing capability. Thermo-chemical simulations are carried out with the help of the Fully Implicit Ablation and Thermal response program (FIAT) for better understanding of the thermo-chemical behavior of the system under the extreme conditions of a space vehicle. Similarly, a structural analysis is performed to determine the structural integrity of the proposed ITPS design. Both the thermo-chemical and structural analyses show that the proposed corrugated-core sandwich structure is viable in terms of recession, pyrolysis, and structural integrity.
