刚性陶瓷瓦热防护系统设计与评价技术研究进展

Rigid ceramic tile thermal protection system (TPS) serve as a critical subsystem for reusable space launch vehicles, with the system design and evaluation technologies directly influencing mission reliability. This review focuses on four major research directions: 1) Structural integrity analysis employs multi-scale models to reveal thermo-mechanical coupling failure modes. 2) Impact resistance research integrates testing with SPH-FEM coupling simulation to establish damage assessment systems. 3) Thermal analysis technologies encompass directions such as probabilistic analysis, optimization design, and mesoscopic heat transfer theory. 4) System reliability assessment combines probabilistic design methods and health monitoring techniques to construct data-driven safety frameworks. Current research trends include multi-scale characterization, intelligent algorithm integration, and deepened international collaboration. Key challenges remain in material mesoscopic heat transfer modeling, reusability evaluation and reliability improvement of connection structure. The findings provide comprehensive technical references for advancing space thermal protection technology development, offering significant guidance for enhancing reusable spacecraft reliability.
