| 摘 要： | 在动叶顶部采用稳态微量喷气可以在不影响低速轴流压气机的稳态工作特性下,拓宽其工作范围。为了分析微喷气作用机理,进行了一系列不同喷气结构的实验研究,包括不同喷气角,不同喷嘴安装位置以及不同喷气量.利用高频响动态传感器测量叶尖间隙动态压力谱,分析表明微量喷气可以改变叶尖顶部泄漏涡的轨迹.

| Abstract: | Steady micro tip injection can improve the stability while the steay characteristic has been kept unchanged.In order to verify the compressor response to micro injection,experiments at various injection comfigurations are performed,which include different injection angles,axial gaps between injector and blade leading edge and the amount of air.Dynamic pressure field in tip clearance is measured by using high frequency response pressure probe.The result shows that micro injection can change the track of the tip leakage vortex. |

| Keywords: | compressor rotating stall micro injection dynamic pressure field |
