Abstract
In order to figure out the temperature field distribution of the launcher and the missile under fire conditions, the geometric model of the launcher and the missile was established. The temperature field of a typical pool fire flame was simulated, and the temperature field distribution of the launcher and internal missile under the typical pool fire flame was calculated. The results show that the maximum temperature of the outer surface of the launcher after firing 3600s is 1238K, the highest temperature of the missile surface can reach 690K, the maximum temperature of the missile center is 333K. The heat transfer by radiation plays a major role in the whole heat transfer process, which accounts for 88.35%.
