First, this paper briefly introduces the present situation and development history of the turboshaft/turboprop engine, as well as the main structural forms and technical features of the compressor in the turboshaft/turboprop engine. Second, the axial compressor of the combined compression system in this type of aero engine is different from high thrust turbofan engine. The special inner flow features and improvement measures of the axial compressor in the turboshaft/turboprop engine are given. The inner flow features of the impeller and diffuser, which are the typical section of the centrifugal compressor, are also discussed. Then, the instability process and stall margin enhancement in the compressor of the turboshaft/turboprop engine is analyzed. The developing trends of the turboshaft/turboprop engine in the future are given.
