摘　　要：本文采用测量转子壁面动态压力的方法,研究了某小型两级轴流压气机的叶尖区流场。测取了n=80%、85%、90%、95%、98.36%和100%状态下两级转子的叶尖泄漏流动参数,并在n=80%、85%、90%时对出口进行节流,测取了第二级转子节流状态的叶尖泄漏流动参数。In this paper, the tip leakage fluid in a small axial compressor was investigated by the mea- surement of dynamic pressure in tip area of rotors. The tip clearance flow parameter at 80%, 85%, 90%, 95%, 98.36%, 100% design speed conditions were gained. When the exit section Was throttled, the tip clearance flow parameter of the second rotor stage at 80%, 85%, 90% design speed conditions were gained.
