Propeller type windmill
The windmill and wind power generation device which can function on a downwind type windmill also as a vertical-axis type windmill
This windmill can track the wind of an omnidirection.
Wind-power generation
In a propeller type windmill of a horizontal shaft type which has the flattery wings projected before and after a circumferential direction of wings aiming at wind-direction tracking in a propeller outer edge.The aforementioned flattery wings have the curved surface curved toward regions of back of a windmill to front-of-solvent slippage to a hand of cut of a propeller, and/or back end slippage, Form where a curved surface of front-of-solvent slippage of the above was formed in periphery slippage of wings, and front-of-solvent slippage moreover deflected only a certain angle to the rotation center side gradually to a circumferential direction is carried out, A rise window type windmill, wherein a curved surface of back end slippage of the above is the curved surface at which a region of rotation center slippage turned toward regions of back of a windmill.
