As the compressor plays a key role in the marine-used gas turbine, its stability determines the operation condition of the power engine of the ship. The paper investigates the performance improvement of the compressor by utilizing a new-designed asymmetric stator. The results show that the flow distortion upstream is significantly constrained by the developed stator and the unsteadiness of the static pressure coefficient and Mach number at R2 inlet decrease by 74% and 48% respectively.
