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。 In this paper, based on the literature [1], the flow field of the tip clearance of WP11 compressor rotor is measured by the dynamic pressure transducer with high frequency response. The test consisted of a gap flow field with multiple throttles at three speeds. The test results show that the overall position of the shock wave moves upstream with the deepening of the throttling flow, but the minimum pressure point on the suction side remains unchanged at 40% or 20% of the chord length. When the shockwave position is behind this point, the secondary leakage directly impacts the shockwave structure. When the shockwave position is before this point, the shockwave structure is only affected by the leading edge leakage.
