| 摘 要： | 根据Lighthill气动声学理论，推导出非均匀栅距结构下压气机转子-静子气动干涉噪声频谱公式。研究的叶栅结构为带进口导叶的单级三排叶栅，其中动叶栅距不变，而导叶和静叶栅距均采用非均匀栅距。计算了各种叶栅结构下转子-静子气动干涉噪声的大小。对不同叶栅结构的计算分析表明：在导叶和静叶采用一定的非均匀栅距组合型式下，在保证压气机级气动性能变化不大的同时，转子-静子干涉噪声能够得到降低。

| Abstract: | The method for aerodynamic noise due to rotor-stator interaction in an axial compressor with unevenly -spaced blades was developed. The main effort is focused on a compressor stage with IGV. The uneven pitch spaces of stator blades and IGV are set in this stage. The rotor-stator interaction noise level was calculated. The numerical results predicted the interaction noise can be decreased with a certain configuration of uneven placed stator blades and IGV. |
