<p>The two vanes (1) of this windmill turbine are identical in shape and are mounted on a vertical rotation shaft (2). The turbulence created by one vane, in the volume between the vanes, develops extra power on the other vane. In vertical cross-section, the vanes have a 'boomerang' shape with two partial ellipses,while in horizontal cross-section they are hyperbolic. The vanes are made from material with a uniform thickness.</p> |
