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。
The gap between the antenna window and the adjacent thermal barrier was measured at Mach numbers 5.0 and 7.8 and corresponding Reynolds numbers per unit length of 4.7 x 107 / m and 3.5 x 107 / m airflow In order to study the influence of the local outflow field, the size of the slit and its orientation on the thermal environment within the antenna window gap.
