WIPO Patent Application WO/2012/090821
Kind Code:
A1
Abstract:
[Problem]
To improve the efficiency of a windmill blade by simplifying the structure.
[Solution]
A rectangle is formed by the rotary shafts of two blades (10) and connecting rods (30) supporting both ends thereof, and at least two yaw control wheels (50) having an axis perpendicular to the plane of the rectangle are provided, and are driven within guides arranged along the direction of tandem movement of the blades, thus controlling yaw. Furthermore, rolling movement control wheels (50) are provided perpendicular to the direction of movement and are driven within guides in the same manner to control rolling.
Furthermore, an elevation angle control wheel is provided in the direction perpendicular to the aforementioned plane of the rectangle and is driven in a guide provided along the direction of tandem movement, and said guide is moved in the direction perpendicular to the direction of tandem movement, thus rotating the blade shafts via the elevation angle control wheel and controlling the elevation angle.
