In order to explore the influence of boundary layer suction on the flow state and aerodynamic performance of transonic compressor rotor, a numerical simulation was carried out. For the flow loss caused by complicated flow structure at the upper end of the compressor rotor, such as the shock wave and the leakage vortex, the boundary layer suction was set at upper end-wall, and the flow rate is 2% of the main flow rate. Three different suction schemes were discussed, the efficiency of final modification scheme is improved by 2.05% and the pressure ratio is improved by 3.34% at most. Results show that the large flow suction in a suitable position of the casing can improve the internal flow state and aerodynamic performance of transonic compressor rotor.
