Results of the investigation of HPC of various types are generalized. We established a law of the automodelling warm-up mode in the ablation from a surface of HPC, a value of the constant of thermal destruction of materials, and the parameter of the non-stationary ablation which allows a calculation of the non-stationary ablation without determination of heat conduction of a material at high temperatures. Calculated and experimental investigations proved that limiting power consumption of internal processes of heat absorption is reached when the thicknesses of warmed and carried away layers of a material become equal.
