Patent 9683547 was granted and assigned to Korea Aerospace Research Institute on June, 2017 by the United States Patent and Trademark Office.
Provided is a wind turbine for generating electric energy using wind power, and more specifically, a wind turbine having a nacelle fence for improving aerodynamic performance by mounting a fence structure on the nacelle of a horizontal axis wind turbine. The wind turbine having a nacelle fence decreases the vortex that is generated at the downstream ends of rotating blades so as to improve the aerodynamic performance of the blades, and increases the power coefficient of the wind turbine.
