| Abstract: | Starting from the source of aerodynamic thermal load,
the principles and progress of a new thermal protection mechanism based on the
physical mechanism of flow control, optical radiation control, atomic
reorganization, and electron dissipation are introduced. The active control of
convection heat, chemical heat and radiant heat is realized from the aspects of
regulating environment and materials, the characteristics and shortcomings of
the development of a new thermal protection mechanism for hypersonic vehicles
are further analyzed, and the suggestions on the key directions of future
research in this field are put forward. |
