The dependence of the effective enthalpy of heat-protective materials on heating conditions is investigated. We derived parameters and equations which allow one to determine the effective enthalpy of a material in view of the non-stationary mode of ablation of weight. A method for the calculation of the non-stationary mode of destruction of a material without resort to high-temperature values of heat conductivity is developed. We present a complex of stands and installations for the study of the high-temperature destruction of materials at convective, radiating and radiating-convective types of heating. The complex is created in IPMS NAS of Ukraine.
