The stator is one of the important components which affect the propulsion efficiency, torque reduction and propeller slipstream rectification, In order to study the mechanism of aerodynamic comprehensive design and parameter influence of stator configuration on aerodynamic propulsion efficiency, de-rotation and paddle slipstream rectification effect of stator. this paper adopts a combination of CFD simulation and wind tunnel test, under the complex interferences of the ducted, the blade, the stator and the engine nacelle, the typical aerodynamic configurations and the parameter influence mechanism on the configuration of the stator were studied; from the aspects of the stator airfoil, the torsion angle and the chord length distribution of stator, the influences of four typical stator configurations on the propulsion efficiency, torque reduction and the influence of slipstream rectification were analyzed. The results showed that a good stator configuration can increase the propulsion efficiency of the ducted propeller by 1%—3% , and offset the total torque of the ducted propeller by about 94.5% .
