摘　　要： 通过紧耦合方法对超声速流动与结构温度场进行耦合计算。首先介绍了超声速气动加热的基本理论,其次利用Fluent软件对初步设计的双头导引头火箭橇进行气动加热仿真分析,建立了流体-热耦合的仿真分析方法,得出不同时刻导引头与陪试品表面对应点的表面温度在逐渐升高,但是增长幅度在逐渐减小,两者具有相同的变化趋势;不同时刻导引头与陪试品表面对应点的热流具有相同的变化趋势,是逐渐下降的。对以后在双头导引头火箭橇试验中,映射、推导导引头表面的温度具有重要的指导意义。 In this paper,tight coupling method is used to coupling compute the supersonic flow and temperature field of the structure.This paper firstly introduces the basic theory of aerodynamic heating,secondly uses software Fluent to make the aerodynamic heating simulation analysis for the rocket sled with double-head seeker,establishes a fluidthermal coupling simulation analysis method.Gets that the temperature and the heat flux are almost the same trend on the corresponding points which are on the surfaces of the seeker and the sample,except that the temperature gradually increases,and the heat flux decreases.It has important guiding significance for the mapping and deriving the temperature of the seeker’s surface in the later test of rocket sled with double-head seeker.
