摘　　要：通过对现有高速再入体热辐射模型的分析计算,确立了目标的本体辐射、激波层辐射和尾流辐射之间的定量关系,从而建立了其修正的热辐射模型。将修正模型的理论计算结果、外场实测结果与实验室缩比模型仿真结果进行分析与比较,得出结论:高速再入体再入大气层时的热辐射模型采用本体辐射、激波层辐射和尾流辐射的修正模型,能更好地反映目标再入时的实际辐射,可以为目标热设计提供更准确的依据。Based on analyzing and computing the reentry object radiation model, the relationship between heat radiation, shock radiation, ablation radiation and retail radiation was given. By analysis of the facts of separating errors between measurement and numerical computation, a revised heat radiation model was established. With comparison of the theoretical results in revised model with the measuring results in exprimental field and simulation results in laboratory,it is concluded that the revised heart radiation model can give the real radiation properties of reentry for Apollo airplane by revision of heat radiation, shock radiation and retail radiation. Although there is difference in the shape and radiation of blunt and tine reentry objects, the gap can be amended by computing.
