With the rapid development of aerospace technology, the development of hypersonic vehicles is gaining more and more attention from all countries. The heat protection problems caused by flying at high speed have become the key constraints and major technical bottlenecks in structural design. In this paper, the basic forms of thermal protection for hypersonic vehicles are briefly introduced. According to the different parts of the thermal environment, the methods of thermal protection and the choice of thermal protection materials are analyzed emphatically. And the development trend of future thermal protection technology for hypersonic vehicles Looking forward.
