  • Patent number: 10801469
    Abstract: A rotor blade assembly for a wind turbine is disclosed with a first blade segment having a female structural member defining an internal cavity, and a second blade segment connected to the first blade segment at a chord-wise extending joint. The second blade segment has a male structural member that is received within the internal cavity of the female structural member of the first blade segment. At least one floating connector, for joining the first and second blade segments, is positioned in at least one of a generally chord-wise direction and a generally span-wise direction. The floating connector has a biasing element configured to restrain bi-directional movement of a floating pin within the floating connector.

  • Publication number: 20200049128
    Abstract: A reinforcing structure for a wind turbine blade is in the form of an elongate stack of layers of pultruded fibrous composite strips supported within a U-shaped channel. The length of each layer is slightly different to create a taper at the ends of the stack; the centre of the stack has five layers, and each end has a single layer. The ends of each layer are chamfered, and the stack is coated with a thin flexible pultruded fibrous composite strip extending the full length of the stack. The reinforcing structure extends along a curved path within the outer shell of the blade. The regions of the outer shell of the blade on either side of the reinforcing structure are filled with structural foam, and the reinforcing structure and the foam are both sandwiched between an inner skin and an outer skin.

  • Patent number: 10290153
    Abstract: Dynamic haptic retargeting can be implemented using world warping techniques and body warping techniques. World warping is applied to improve an alignment between a virtual object and a physical object, while body warping is applied to redirect a user's motion to increase a likelihood that a physical hand will reach the physical object at the same time a virtual representation of the hand reaches the virtual object. Threshold values and/or a combination of world warping a body warping can be used to mitigate negative impacts that may be caused by using either technique excessively or independently.

  • Patent number: 9617981
    Abstract: The invention relates to a wind turbine blade bearing removal apparatus and method for facilitating the change-over of the blade root bearing assembly (58) of a wind turbine blade (54). A plurality of support shoulders or yokes (60) are located on the hub (50) of the wind turbine rotor and provide attachment points for respective actuators (62). Corresponding attachment points (66) are provided in the wind turbine blade (54) via a blade support (section 64), which is constructed in the blade between the blade root bearing assembly (58) and the tip. The actuators (62) are mounted between the hub (50) and the blade root bearing assembly (58) and therefore support the blade (54) in a suspended position when the bearing is to be retained. The actuators (62) allow the blade to be easily reattached to the hub (50) when the blade root bearing replacement is completed.

  • Patent number: 9388789
    Abstract: The invention relates to a sectional blade for a wind turbine, the blade comprising at least a first blade section and a second blade section extending in opposite directions from a blade joint, where each blade section comprises a spar section forming a structural member and extending in the longitudinal direction of the blade, and where the first and second blade sections are connected by fastening means restraining any movement of the first blade section relative to the second blade section length ways. The first and the second blade sections are structurally connected by a spar bridge protruding from one of the blade sections and terminating axially in an end portion, which is received in the spar section of the other blade section. The spar bridge and the spar section have interlocking shapes by which rotation of the spar bridge in the spar section is prevented thereby preventing rotation of one of the blade sections relative to the other.

  • Patent number: 9068559
    Abstract: The invention relates to a rotor blade for a wind turbine. The rotor blade comprises a shell and a spar forming a longitudinally extending hollow structure within the shell and comprising: a leading web, a trailing web, and one or more additional webs. Each additional web defines an intermediate portion between a hub end and a tip end. The intermediate portion of each additional web is spaced apart from the leading and trailing webs and at least one of the tip and the hub ends is connected to or integral with the leading or the trailing web. The invention further relates to a wind turbine comprising the rotor blade, and a method for manufacturing the rotor blade.

  • Patent number: 9032622
    Abstract: An elongate web is attached to the root end of a spar of a wind turbine rotor blade to provide additional support along the width of the blade. The root end is formed by a winding operation, and a recess is then cut into the surface of the spar. The recess is defined by a relatively large first, cylindrical surface, which is coaxial with the longitudinal axis of the root end, and a relatively small second, conical surface. A tapered end of the elongate web is attached within the recess of the root end using a layer of suitable adhesive and an array of pins. Resilient spacer elements are arranged within the recess so as to surround the pins. The large area of the cylindrical surface causes the tensile and compressive stresses which arise along the elongate web in use to be transmitted to the spar as shear stresses.
