  • Patent number: 11466660
    Abstract: A downwind morphing rotor that exhibits bending loads that will be reduced by aligning the rotor blades with the composite forces. This reduces the net loads on the blades which therefore allow for a reduced blade mass for a given maximum stress. The downwind morphing varies the amount of downstream deflection as a function of wind speed, where the rotor blades are generally fully-aligned to non-azimuthal forces for wind speeds between rated and cut-out conditions, while only the outer segments of the blades are generally aligned between cut-in and rated wind speeds. This alignment for large (MW-scale) rated turbines results in much larger downstream deflections of the blades at high wind speeds as compared to that of a conventional rigid single-piece upwind turbine blade.

  • Patent number: 11391262
    Abstract: A fluid-driven power generation unit, may include two sets of airfoils disposed on opposite sides of the power generation unit with their leading edges facing a windward end of the power generation unit; a body element having a curved front face and a back disposed, wherein at least a portion of the elongate body element is disposed between the first and second set of airfoils; and a power generation unit disposed in alignment with the body element, the power generation unit including at least a housing, and a turbine and an electrical generation unit actuated by the turbine disposed within the housing. As a fluid flows across the airfoils, the lifting force of the airfoils causes a reduced pressure within the power generation unit, drawing air past the turbine, through the body element and out the back of the body element, thereby extracting power from this secondary fluid flow stream.

  • Patent number: 11371489
    Abstract: A tower for a wind turbine is disclosed, said wind turbine comprises the tower, a nacelle and a rotor having at least one rotor blade. The tower is configured for supporting the nacelle and the rotor on a support system. The tower itself may be structured as having an upper top end for supporting the nacelle and a lower support end for being placed on the support system. Electric energy generated is transported via power cables from the nacelle to an electric grid, preferably via power electronic components, switches and/or transformers. Furthermore, the nacelle may rotate around the yaw axis according to the current wind direction. Hence, the rotation of the nacelle introduces a twist into the power cables, wherein said twist causes a deviation (shortening) in the length of the power cables. Furthermore, the tower comprises at least one radial cable guiding device for receiving the cable and a cable support arrangement for supporting the cable in a beneficial manner.

  • Patent number: 11365714
    Abstract: A method for mounting or dismounting a wind turbine component of an energy generating unit in a multirotor wind turbine is disclosed. The multirotor wind turbine comprises a tower configured to support one or more load carrying structures each arranged for supporting at least two energy generating units arranged at or near its ends and at opposite sides of the tower. The method comprises securing the load carrying structure against up and down tilting movements before positioning or dispositioning the wind turbine component at an end of the load carrying structure thereby reducing the loadings arising from the unbalance caused by the positioning or dispositioning the wind turbine component. The securing may be realized by compression bars, tethering, or the use of a counterweight.
