PURPOSE: A Savonius windmill blade is provided to obtain the high rotating force by maximizing the difference of drag force. CONSTITUTION: Dampers of plane blade shape are stuck to turbine blades(11,12). The turbine blades(11,12) are combined with a rotating shaft(15). Turbine blades(13,14) are crossed against the turbine blades(11,12) and combined with the rotating shaft(15). Many turbine blades are combined at the same method. Drag force of the turbine blade(11) is larger than drag force of the turbine blade(12). The turbine blades are rotated clockwise by generating rotating torque. The drag force is maximized when the wind face of the turbine blade(11) is a right angle to the wind direction. In minimizing the drag force, the drag force of the turbine blade(13) is maximized. Thereby, the rotation is performed smoothly. |
