In order to explore the feasibility of the application of non-axisymmetric bowed and swept stator blades in compressor and the improvement effect of the parameters of the bowed and swept stator blades on the distorted flow field，this paper took the sector cascade test piece as the research object to study the influence of geometric parameters of non-axisymmetric bowed and swept stator blades on distorted flow field by using the numerical simulation method. The positive bowed，negative bowed, forward swept and backward swept stator blades were set in the position seriously affected by inlet distortion to form different non-axisymmetric stator blade modeling schemes, and explore the improvement of stator blade flow field. The results show that Nbow-0.5-10 can reduce the flow field loss by 2.75%, forward sweep has a better inhibitory effect on total pressure loss, while backward sweep has a slightly less effective effect on total pressure loss than forward sweep, but it is beneficial to reduce the loss in the main flow.
