Title:
WIND TURBINE
Document Type and Number:
WIPO Patent Application WO/2012/030066
Kind Code:
A2
Abstract:
The present invention relates to a wind turbine in which the blades are improved in structure so as to improve torque. The wind turbine includes: a structural body forming an overall frame; a rotation unit coupled to the structural body; and a plurality of blades connected to the rotation unit. Formed on the end of the blade are a first round coupled to the rotation unit and a second round having a radius of curvature greater than that of the first round. Also, the blade includes a streamlined sail part connecting the first and second rounds to each other to form an overall S-curve shape. The second round is gradually inclined from the lower end thereof toward the upper end. Thus, the wind which rotates the blades is not discharged to the outside, but is introduced into the turbine to act as a force for rotating the blades again, thereby improving efficiency. In addition, the wind turbine provides structural stability and installation convenience.
