First of all, the current situation and development course of turbine / turboprop engine and the main structure and technical characteristics of turbine / turboprop engine compressor are introduced. Secondly, from the point of view of the characteristics of the internal flow of the compressor, the internal flow characteristics and flow field improvement measures of the axial-flow compressor in a turbofan / turboprop engine are compared in detail. Turboshaft / turboprop engines commonly used in centrifugal centrifugal impeller and diffuser internal flow and matching characteristics. Then, the flow instability and stability expansion measures inside the turboshaft / turboprop compressor were analyzed. Finally, the future development trend of turboshaft / turboprop engine compressor is prospected.
