In order to understand the flow characteristics in highly loaded stator and study the influence of the boundary layer suction on the aerodynamic performance in stator, the experimental and numerical methods were adopted for aerodynamic performance analysis of a final stage stator cascade of a highly loaded fan. Aerodynamic performances of the stator cascade under high incidence Mach number were analyzed. The influence of boundary layer suction on the aerodynamic performance in highly loaded stator was studied. Results show that with the increase of suction mass flow, the turning ability of airflow increases, the deviation angle decreases 2°～3°; the capability of pressure diffusion increases, and the outlet Mach number decreases 0.03～0.07; the optimum value was reached when the suction mass flow increases to 0.08kg/s, the deviation angle and the outlet Mach number decrease to the minimum, but when the suction mass flow continues increasing, the deviation angle and the outlet Mach number increase.
