For improving the static pressure ratio and total pressure recovery coefficient of axial compressor tandem stators at different airflow incidences, a three-dimensional compressor blade design method of composite sweep and dihedral was applied to conduct a bi-objective aerodynamic optimization to the shapes of front and rear blades. The results of this optimization research show that the optimal design with sweep and dihedral can significantly suppress the airflow separation in the flow passage at positive incidence and alleviate the airflow blockage in the slot between front and rear blades at negative incidence. At positive and negative incidences, the static pressure ratios of the optimal design increase by 0.99% and 0.71%, respectively, and the total pressure recovery coefficients increase by 0.89% and 0.72%, respectively.
