大尺度空气舵超声速烧蚀热结构试验

Ablation-Thermal-Structure Test of Large Scale Air Vane in Supersonic Flow

针对全尺寸大尺度空气舵热环境参数,对地面试验的流场参数进行了计算,设计了测试探头,进行了流场校测。将校测结果与计算结果进行了比较分析,结果表明二者吻合较好,最大偏差在30%以内。校测后的流场已成功应用于试验。

The ground test flow field parameters were computed based on the thermal conditions of the large full scale air vane, The test flow field parameters were also measured. The parameters computed accorded well with those measured. The maximum apparent error is below 30%. The flow field measured is used in tests successfully.
