摘　　要：在马赫数为５．０和７．８，相应的单位长度雷诺数为４．７×１０７／米和３．５×１０７／米气流条件下，测量了天线窗与相邻防热层间缝隙的热流率分布，以研究局部外流场、缝隙尺寸及其取向对天线窗缝隙内热环境的影响。Detailed heat transfer distributions have been measured inside the gap between a antenna window and the adjacent heatshield. The nominal test conditions werefreestream Mach number of 5. 0 and 7. 8,unit Reynolds number of 4.7×107/m and 3.5×107/m respectively. The effects of local external flowfield, gap size and orientation on thermal enviroment inside the gap of a antenna window were researched.
