  • Publication number: 20200063718
    Abstract: The invention relates to a leading edge protection cover for a wind turbine blade. The protection cover comprises first and second longitudinally extending edges, and outer and inner arcuate surfaces extending there between. The inner arcuate surface is shaped to be attached to an outer surface portion of the wind turbine blade such as to cover at least a part of the leading edge of the blade, and with the first longitudinally extending edge being attached to a suction side of the wind turbine blade. The protection cover further comprises a number of vortex generating members positioned on the outer arcuate surface of the protection cover along at least a part of the first longitudinally extending edge. The proposed protection cover results in an increased protection of the wind turbine blade against impacting particles and improved fluid properties over the surface of the wind turbine blade.

  • Publication number: 20190293050
    Abstract: The invention relates to a method of preparing a wind turbine blade with a leading edge protection. The method includes applying a first layer of paint on the surface portion comprising the part of the leading edge to be protected, applying a layer of a fibrous material on top of the first layer of paint, applying a second layer of paint on the layer of fibrous material, and allowing the applied leading edge protection to cure. The method may be performed as a part of the manufacture of the blade and/or as a post-processing step for example during repair on site. The proposed method results in an increased erosion resistance and improved protection against impacting particles. The invention further relates to a wind turbine blade comprising a leading edge protection established as mentioned above.

  • Patent number: 9982654
    Abstract: Wind turbine having a wind turbine tower, a nacelle provided on the wind turbine tower, a rotor hub rotatably mounted to the nacelle, and one or more wind turbine blades having a root end to be mounted to the rotor hub, a tip end, and pressure and suction sides connected to each other via a leading edge and a trailing edge. The wind turbine blade has a plurality of cross-sectional profiles arranged according to the surface of the suction side so that the surface of the suction side forms a line having a predetermined curvature which curves towards the pressure side of the wind turbine blade and/or forms an approximately straight line along at least part of the relative length. The line crosses each cross-sectional profile in that point on the pressure side where the maximum relative thickness of that profile perpendicular relative to its chord line is measured.

  • Patent number: 9759187
    Abstract: A wind turbine with a wind turbine tower, a nacelle on the tower, a rotor hub rotatably mounted to the nacelle, and at least one wind turbine blade having a blade root mounted to the rotor hub, a tip end, a pressure side and a suction side connected to each other via a leading edge and a trailing edge, a first shell part having inner and outer surfaces and a second shell part having inner and outer surfaces, the shell parts having flanges that extend outwards from the trailing edge of the shell parts and away from the outer surface with gluing surfaces which are glued together when the two shell parts are placed on top of each other. This allows the glue line to be moved out of the inner area defined by the shell parts so that the glue process can be controlled more effectively.

  • Patent number: 9168858
    Abstract: The invention relates to a method for transporting two or three pre-bend wind turbine blades for a wind turbine and to a wind turbine blade transport unit, the wind turbine blades each having a length extending from a first end, e.g. a root end describing a first end plane, to a second end, e.g. a tip end, where the length is at least 35 meters, the wind turbine blades each having a central longitudinal axis extending perpendicular from the first end plane and towards the second end, the wind turbine blade additionally having an aerodynamically shaped body having a pressure side, a suction side, a leading edge and a trailing edge. The wind turbine blades are fixed in specific positions in relation to one or two other wind turbine blades as a single transport unit.

  • Publication number: 20140369845
    Abstract: The present invention relates to a manufacturing method for wind turbine blade and a wind turbine manufactured according to that method. The wind turbine blade comprises two shell parts wherein each shell part has a leading edge connected to a trailing edge via an inner surface. One of the two shell parts comprises an extended shell section which is configured as a flexible shell section. The shell section is configured to flex in a radial direction from a first position to a second position relative to the leading edge when an incoming wind is acting on the pressure side of the wind turbine blade. The wind turbine blade may be manufactured using a non-bonding layer removable arranged adjacent to the glue line between the two shell parts which reduces the amount of manual grinding or polishing of the glue region. This provides a wind turbine blade with an improved blade characteristic where the extended flexible shell section is specifically designed to have significant flexibility.
