Abstract:

With the development of hypersonic vehicles, aerodynamic heat loads on thermal protection materials under high enthalpy disassociated environment is affected by surface catalytic properties to a large extent. According to the research development in characterization of high enthalpy environment and surface catalytic properties, this paper presents an overview of surface catalytic mechanism and catalytic model of different scales, analyzing and discussing ground based surface catalytic tests and evaluation methods and the influence factors of surface catalytic properties for the typical thermal protection materials. A brief summary of the preliminary results of catalytic properties at this stage is made. Based on this, we analyze the insufficiencies in the current test and characterization methods of surface catalytic properties and propose the corresponding future research area, giving instructions on the improvement of surface catalytic properties experimental test methods, which will lead to a precise prediction of aerodynamic heat environment and finally a more accurate thermal protection system design.

Key words: thermal protection materials, surface catalytic properties, simulation calculation, characterization methods, test and evaluation, influence factors
