The large-scale wind turbines with the grid connection system operated in wind farms are being used for the power generation in many nations. On the other hand, the small-scale wind turbines have been used as the independent source of power regardless of the places. In resent years, these small wind turbines are employed for street lights, park lights, environmental monuments and power sources for emergencies. Among such trends, sail-wing windmills are revaluated in the modern society because of their safety, reduced noise and attractive appearance. Therefore, in the present study, the authors made the vertical axis sail-wing type variable paddle windmill with link mechanism and evaluated their aerodynamic performance to find the optimal shape and configuration experimentally in a wind tunnel. The results show that the windmill with -20deg angle of adjustment has the maximum power coefficient of C_p=0.325.
