Title:
VERTICAL AXIS-TYPE WIND TURBINE
Document Type and Number:
WIPO Patent Application WO/2019/111674
Kind Code:
A1
Abstract:
Provided is a vertical axis-type wind turbine which provides extremely high energy conversion efficiency exceeding the performance of a known high-efficiency vertical axis wind turbine in which blades are subjected to heaving motion. The vertical axis-type wind turbine 1 is provided with blades 5 which rotate around a vertically mounted rotating shaft 2, wherein, by means of a heaving motion providing mechanism, the blades 5 rotating around the rotating shaft 2 are subjected to rotating orbital motion other than that of a circular orbit, and, during rotating orbital motion of the blades 5, at least the blades 5 are subjected to a pitching angle varying operation for varying the pitching angle of the blades.
