Vertical spiral angle wind turbine |
摘要 |
The present device is a vertically oriented wind turbine blade having a rectangular curvilinear shaped blade which includes a top edge, a bottom edge, an outer edge, a helical inner edge, an inner surface and an outer surface. The blade's top edge is curved and defines a radius R and the helical inner edge defines an angle theta relative to a vertical reference line. The blade further includes an L shaped outer rib with a transverse leg mounted to the inner surface and extending along the outer edge, the outer rib also includes a perpendicular leg extending perpendicular to the transverse leg. |
