ABSTRAKT

This paper specifies the main modeling conditions for the hypersonic high-enthalpy air flow interaction with the thermal protection materials of airspace vehicles. The methodology and technique of the experiments on high-temperature material thermochemical stability in a hypersonic plasma flow are given. The gas corrosion of a number of refractory ceramics and carbon-carbon materials at sample temperatures of 1000-2500 K at regimes that model the space vehicle atmospheric entry is investigated. The influence of mechanical load on the oxidation intensity of the studied carbon-carbon materials is considered.
