Abstract:

Thermal protection material and structure is one of the key technologies enabling near space hypersonic flights. For the past few years, new design and analysis methods have constantly emerged. This paper will focus on these new concepts and technologies, and a survey of literature reveals that: design of thermal protection materials has been developed according to ab initio method on atomic or molecular scale to meet specific needs, and active protection technology with environment management is on the course; thermal protection structures are not only expected to be capable of thermal protection and load bearing, but also multifunctional and diversified by new thermal protection mechanism and concepts; more attention has been paid to multi-scale multi-physics non-deterministic methods under complex real service conditions in thermal protection structure analysis approaches. These new concepts and technologies will constantly drive innovations and revolutions in thermal protection technology.

Key words: thermal protection, material design, structure design, new concept, innovation technology
