VERTICAL SHAFT TYPE DARIUS WINDMILL

Title:

VERTICAL SHAFT TYPE DARIUS WINDMILL

Document Type and Number:

WIPO Patent Application WO/2010/013981

Kind Code:

A3

Abstract:

The present invention relates to a Darius windmill, and more specifically, to a vertical shaft type Darius windmill that enables self-start in the low wind velocity range. The Darius windmill, in which a first vertical rotational shaft is rotated by the lift generated by a first blade, has a starting means for assisting the starting or rotation of the first rotational shaft at a low wind velocity. The present invention provides advantages of enabling self-start and rotation due to the lift generated by the blade in low wind velocity conditions and enabling the generation of rotational moments in any wind direction or wind velocity, thereby easily starting even in urban areas with very low wind velocities or large variations in wind direction, and thus enabling the generation of electricity over a wide range of wind velocities.
