Title:
VERTICAL AXIS WIND TURBINE HAVING RADIAL WIND CHAMBERS
Document Type and Number:
WIPO Patent Application WO/2010/085019
Kind Code:
A1
Abstract:
The present invention relates to a vertical axis wind turbine which uses air resistance against horizontal wind in a remarkably efficient manner and uses the horizontal wind as a rotating energy, thereby generating electrical power with high efficiency. The radial disk-type vertical axis wind turbine of the present invention operates smoothly even with weak wind forces and operates efficiently even with frequently varying wind directions. In detail, to utilize wind forces in the most efficient manner in an aerodynamic aspect, the radial disk-type vertical axis wind turbine of the present invention is configured such that upper and lower radial blades and external blades are maximally spread, and wind forces are introduced into the upper and lower blades and the external blades to form a plurality of wind chambers and to maximize the resistance against the wind forces, in the section in which the turbine rotates in the wind blowing direction, and all of the blades are folded to minimize frictional resistance of the wind in the section in which the turbine rotates in the direction opposite to the wind blowing direction, thereby maximizing the rotating energy of the wind turbine.
