Research status of hypersonic vehicle fluid-thermal-solid coupling and software development

The study of fluid-thermal-structural coupling problem is particularly important for the design and evaluation of the thermal protection system of a new generation hypersonic vehicle. A review of the state-of-the-art of hypersonic vehicle fluid-thermal-solid coupling problem is provided. This paper briefly reviews the history and current status of the development of hypersonic vehicle. Starting from the physical definition, the coupling relationship of the hypersonic fluid-thermal-solid coupling problem in various disciplines and their modeling methods are summarized. Progress in the hypersonic vehicle fluid-thermal-solid coupling problem, especially in multidisciplinary coupling analysis strategies/methods, are summarized.The coupled analysis platform for thermal environment and structure response (FL-CAPTER) developed by China Aerodynamic Research and Development Center are introduced with respect to platform framework, function modules, coupling methods and technical features. Finally, challenges and future directions in hypersonic vehicle fluid-thermal-solid coupling problem are outlined.
