摘　　要：在亚音速低速风洞上,对9FA重型燃气轮机压气机第7级静叶栅进行了吹风试验。为了考察叶栅的变冲角气动特性,在0°和±7°冲角下完成吹风试验。对试验结果的理论分析表明,该压气机静叶栅借助叶片前掠和下端壁子午型线收敛控制叶片表面后部增压段长度和增压率分布,获得了较为优良的气动性能。On low speed subsonic wind tunnel, the wind test of the stator cascade of the compressorseventh stage of heavy duty gas turbine 9FA was carried out. In order to investigate the aerodynamic performance of the cascade at different incidences, the test was carried under 0 degree and ±10 degree incidence. Theoretical analysis of the test results show that, by the front blade sweep and the meridian line convergence on the lower endwall to control the length of the pressurized section in the rear of the blade surfaceand the rate of the increase pressure, the compressor stator cascade obtain the excellent aerodynamic performance.
