MUMBAI, India, July 25 -- Intellectual Property India has published a patent application (202517064581 A) filed by Zhejiang Goldwind Science & Technology Co. Ltd., Zhejiang, China, on July 7, for 'forward swept fan blade, design method and manufacturing method therefor and wind turbine.'
Inventor(s) include Zhou, Jingwei; and Zhai, Endi.
The application for the patent was published on July 25, under issue no. 30/2025.
According to the abstract released by the Intellectual Property India: "The present application relates to a forward swept fan blade, a design method and manufacturing method therefor and a wind turbine. The forward swept fan blade comprises: a blade body, extending in the length spanwise direction between a root and a tip of the blade; and a pitch axis, extending and vertically penetrating through the center of a root circle. With respect to the pitch axis, on the downstream side of the middle of the blade in the length spanwise direction, the blade deviates in a direction from a trailing edge to a leading edge. Using the forward swept fan blade in the embodiment of the present application can enable the blade to generate forward torsional deformation during operation, so as to counteract the trend of the blade deviating from the optimal lift-to-drag ratio, thus achieving the purpose of minimum loss of the optimal power coefficient at different rotating speeds, and increasing the overall power generating capacity of wind turbines."
The patent application was internationally filed on Jan. 02, 2024, under International application No.PCT/CN2024/070206.
