In order to reduce design parameters and shorten design cycle, Joukowksky profile was utilized to construct torque converter stator blade. By simplifying the Joukowksky equation and adding a thickness term to its end, the Joukowksky stator blade model was given. According to fitting results, Joukowksky is able to present the existing stator blades and hence is suitable for stator blade design. Afterwards, the archive-based micro genetic algorithm was employed to optimize the Joukowksky stator blade based on an integrated 3D blade design system. The results indicated that the Joukowksky profile could be used in stator blade design with less parameters and the performances were improved after the optimization.
