    Omegawind SRL Gets Patent for Rotor Unit of a Wind Turbine Having Foldable Wind Blades and Wind Turbine Comprising Rotor Unit

    November 17, 2021 - Energy Patent News


      Alexandria, Nov. 17 -- Omegawind SRL has received a patent for rotor unit of a wind turbine having foldable wind blades and wind turbine comprising rotor unit. Garaviani Daniele developed the invention. The patent application number is 16/097,105. The International Patent Classification codes are F03D 1/06 (20060101), F03D 7/04 (20060101) and F03D 9/25 (20160101). Cooperative Patent Classification codes are F03D 1/0675 (20130101), F03D 1/0658 (20130101), F03D 9/25 (20160501), F05B 2240/30 (20130101) and F03D 7/042 (20130101).

      The abstract released by U.S. Patent and Trademark Office states, "A rotor unit for a folding blade wind turbine. The turbine includes two blades rotatable with respect to each other between an open position and a folded position. In the open position, the two blades are arranged angularly spaced from each other in order to be able to be affected by the wind to rotate the rotor body. In the folded position, the two blades are arranged angularly close to each other so as to reduce the aerodynamic resistance of the wind turbine. The rotor unit is connectable to an electric generator to generate electric energy by the rotation of the rotor body when the blades are in the open position. The rotor unit includes two blade folding structures connected to the rotor body and pivotally connected to each other about a single hinge axis."
