对旋转畸变条件下轴流压气机的失稳特性进行了实验研究,结果表明,畸变影响区内叶顶泄漏流的前缘溢出造成了旋转失速的提前发生,缩减了压气机的失稳裕度.叶顶微喷气方法有效地提高了旋转畸变条件下轴流压气机的失稳裕度,其原因在于,实施叶顶微喷气后,临近失速时,压气机顶部畸变区诱发的分离团受到抑制,减少了其诱发旋转失速的可能性,从而实现扩稳目的. The experimental study on the instability characteristics of axial flow compressor under rotating distortion shows that the leading edge overflow of the tip leakage flow in the distorted area causes the premature rotation stall and reduces the instability margin of the compressor The method of blade tip micro jet enhances the instability margin of the axial flow compressor under the condition of rotational distortion. The reason is that after the tip micro-jet, near the stall, the separation group induced by the distorted area of ​​the compressor is suppressed , Reducing the possibility of induced spin-stall, so as to achieve the purpose of expanding.
