Mathematical modeling of high-temperature thermophysical characteristics of rubber-like thermal protection materials

Abstract

Based on analyzing and generalizing results of theoretical and experimental investigations of main regularities of heat transfer in the thermal protection of the combustion chamber, the mathematical and computer models of high-temperature characteristics of rubber-like thermal protection materials are formulated. The distinctive feature of the models is taking into account the change in the composition and structure of the destructing material in the process of heating up to high temperatures. Results of the numerical simulation satisfactorily agree with experimental data.
