摘　　要：针对低速轴流压缩系统 ,从理论分析和试验验证两个方面论述了静子在轴流压气机气动稳定性方面的作用。理论上论证了 ,当静子非首先失速部件时 ,其作用有利于抑制扰动的发展 ,增强压气机的气动稳定性 ;试验验证了 ,随着转静子之间轴向间距的减小 ,静子的增稳作用增强 。The effect of stator on axial compressor aerodynamic stability was studied both theoretically and experimentally for a low speed compression system. The theoretical analysis shows that stator could suppress flow disturbances in compressors and enhance the compressor stability, in case of the stator does not stall first. The experimental results of a low speed single stage compressor show that stall flow coefficient decreases with the decrease of the axial spacing between rotor and stator because of the increasing influence of the stator.
