Abstract

In the process of target re-entry, since the target enters the atmosphere at a high speed, the violent friction between the target and the atmosphere generates aerodynamic heat, which makes the target surface heat up rapidly and generates a strong radiation signal. It is an important factor in the target detection process. In order to calculate the surface temperature caused by the aerothermal effect quickly, a rapid prediction model of temperature characteristics is proposed in this paper. Based on the temperature of stagnation point and the surface temperature distribution obtained by the summary analysis with accurate simulation calculation, The surface temperature distribution characteristics during the target re-entry process can be estimated quickly.
