Design method applied to ablation type thermal protection system

The invention discloses a design method applied to an ablation type thermal protection system. The considered uncertainty input parameters quantify various uncertainty random parameters, and a sampling technology is adopted to generate random input samples; then, deterministic aerodynamic heat and heat conduction analysis is conducted on the randomly input samples, and the temperature characteristic quantity of the highest back temperature of the thermal protection system in the whole flight process serves as an output variable; then, on the basis of a small number of generated random samples, an agent model of random input sample variables and output variables is constructed, and precision verification is conducted on the agent model; and finally, carrying out mass sample rapid calculation on the agent model meeting the precision requirement, analyzing probability distribution characteristics of output characteristics, and carrying out sensitivity calculation analysis on uncertainty parameters.
