The study of flow-heat-solid coupling problem of a new generation of hypersonic vehicles is particularly important for accurate assessment and design of the thermal protection system structure of an aircraft. The development history and present situation of hypersonic vehicle flow-heat-solid coupling are reviewed. Starting from the physical meaning, the coupling relationship between hypersonic flow-thermo-mechanical coupling problems and their respective modeling methods are summarized. The research progress on the flow-thermo-mechanical coupling of hypersonic vehicles, especially the coupled strategy / method of flow-heat-solid multi-field coupling, is summarized. From the platform framework, functional modules, coupling methods and technical features, this paper describes the FL-CAPTER platform developed independently by China Aerodynamics Research and Development Center. Finally, the problems and trends in the development of hypersonic vehicle flow-thermo-mechanical coupling are discussed.
