摘　　要：依据实验测量结果，本文给出了一单级轴流压气机在反流状态下气动参数沿径向的分布情形，分析了在反流状态下压气机中气流流动的特点。The experiments of reverse flow in a single-stage axial-flow compressor were completed.The parameters,such as velocities,static and total pressure,incidence and deviation,were measured at three sections:the inlet section of rotor,the section between rotor and stator,the outlet of stator.The pressures and temperatures of the flow are measured with a steady acquisition system.The experimental results show that,uniform flow parameters are obtained at the outlet section of stator,but the parameters in the inlet section of rotor vary obviously at the radial direction.The incidences of the reverse flow are very large,so there exists a great loss.Therefore,the temeprature rises as the gas flow through the compressor reversely.
