At a small certain blade angle range condition, the orientation of the concave side of the blade. It can significantly improve the efficiency of small vertical wind turbine.
Based on patent 7967569, it further specifies the relationship between blade width and wind wheel diameter ratio. Further improve the small vertical wind turbine efficiency.
About the positive pitch angle regulation structure. It is for over-speed protection when the wind speed over the rated wind speed. It can significantly improve power generation wind speed range of the small wind turbine.
