Abstract:
According to the phase transition theory, based on the ablation principles of carbon-base and silicon-base composites, the thermal conduction equation, and energy balance principle, one-dimensional non-steady ablation model is established and the ablation of the C/C-SiC thermal protection composites is simulated. The results of numerical simulation are in good agreement with the data of experiments. The results of numerical simulation show that, in the same ablation environment, for the C/C composites the ablative velocity is the highest and the temperature inside the material is the lowest, while in Sic composites the velocity is the lowest and temperature is the highest. C/C-SiC thermal protection composites combine the advantages of C/C composites and SiC composites, which has lower ablative velocity and lower temperature.
