**Modeling and Analysis of Fluid-Thermal-Structure**

To efficiently model fluid-thermal-structural problems for thermal protection design of hypersonic vehicles, a framework of Hypersonic Computational Coupling Dynamics (HyCCD) software integrates an independently developed program solving hypersonic aerthermodynamic simulation with a finite element analysis professional software. With the mathematical and physical description of multi-physics coupling mechanism, the corresponding efficient coupling strategies were proposed. Some representative coupling problems encountered in hypersonic vehicle were systematically analyzed to study the intrinsic fluid-thermal-structural coupling characteristics and mechanisms. The results can theoretically and technically support the studies on comprehensive performance assessment and optimization of thermal protection system and static or dynamic aero-

In recent years, with the ramjet engine matures and scramjet engine has achieved remarkable progress, a new-generation hypersonic vehicle powered by air-breathing engine has attracted widespread concerns in the international community and has become the focus of the future development in the field of aerospace. However, the development of this new generation air-breathing hypersonic vehicle faces many new key issues and requires great progresses in aerodynamics, structure thermal protection, propulsion technology and flight control [1, 2]. The sustained long-range maneuverable flight in the near-space atmosphere within a wide Mach range makes the experience of aerodynamic environment surrounding the hypersonic
