Based on the theory and semi-empirical formulas, the surface heating flux of warhead at zero attack angle under aerodynamic heating is calculated by using reference enthalpy method, and the equilibrium curves of temperature for radiation of wall are obtained, by which the anti-thermal effects of blunt leading edge is proved in this paper. At the same time, the anti-thermal effects of thermal protection system with opposing jet are simulated by using methods of CFD. The heating flux of wall under opposing jet is predicted, and the numerical simulation results are well agreement with the experiment results.
