  • Three-vaned drag-type wind turbine
    Patent number: 7896608
    Abstract: A novel three-vaned, drag-type wind turbine, wherein air, when it exits a first vane, is split into two flow paths. A first path is directed to a second vane, while a second path is directed to a third vane. The air, then, impinges on a plurality of vanes wherein the momentum of the air is altered, thus providing the force needed to drive the wind turbine. In a first embodiment, a wind shield is used to deflect a portion of the wind from entering the wind turbine, this portion being in a region where the vanes are rotating into the wind. In second embodiment, the wind shield is not used.
