In this study, the improvement of the starting performance of a Darrieus wind turbine with straight wings was investigated. The numerical simulation on the starting torque generated in the stationary Darrieus wind turbine was executed. The parameters used for the numerical simulation are wing section shape and wing setting angle. The wing sections tried were NACA0018, NACA4418 (camber inside), and NACA4418 (camber outside). The following conclusions were obtained in this study. In three kinds of wing sections in which wing setting angle is set in 0 degrees, NACA0018 performs the highest minimum starting torque. In case that the setting angle of NACA0018 is set in-5 degrees, the starting performance improves more than the setting angle 0 degrees.
