本文利用高频响动态压力传感器，在文献［1］的基础上，对WP11压气机转子叶尖间隙流场进行了流场测量。测试包括三个转速多个节流条件下的间隙流场。测试结果表明：激波总体位置随节流加深而向上游移动，但吸力面最小压力点基本维持在40%或20%弦长处不变。当激波位置在该点之后时，二次漏流直接冲击激波结构；当激波位置在该点之前时，激波结构基本只受前缘漏流的影响
High frequency response unsteady pressure transducers wereused to investigate tip clearance flow structures in a transonic compressorrotor. Shock structures and their interactions with tip clearance leakageflow are studied in the present paper from open throttleoperating condition to stall for three corrected rotating speeds. The position of minimum static pressure locates at 40% or 20% chord length,and keeps the position for the different operating conditions, although thepassage shock moves upstream with closing outlet throttle. When the impactingpoint of shock on suction surface locates behind the minimum pressure,secondary leakage flow distorts the passage shock directly,otherwise, leading edge leakage flow effects much upon the passage shock wave
