Abstract

Рroposed a physical and mathematical model of heat and mass transfer in a destructive heat protective material. For modeling, the thermophysical characteristics of the material (density, thermal conductivity, heat capacity) and the kinetic parameters of degradation were studied using thermoanalytical research methods. The temperature and density fields of the destructive material were simulated during the descent of the vehicle from the earth's orbit along the model trajectory characteristic of space vehicles. The features of the heating of the sample of heat protective material and the depth of the destructed layer at the final moment of time of calculation are revealed.
