Abstract: The present disclosure is directed to a tip extension assembly for a rotor blade of a wind turbine. The tip extension assembly includes a tip extension having a body with a pressure side surface and a suction side surface. Further, the tip extension is slidable onto a tip of the rotor blade so as to overlap the rotor blade adjacent the tip. In addition, the tip extension defines an extended trailing edge of the rotor blade. Moreover, an edge of the tip extension defines a step profile at a transition region between the tip extension and a trailing edge of the rotor blade. The tip extension assembly also includes at least one chord extension configured for attachment adjacent to the edge of the tip extension so as to minimize the step profile and associated noise caused thereby.

Abstract: A method for installing an add-on component onto a tip of a wind turbine blade, the associated blade, and the component, are provided. The add-on component has a span-wise end and a separated trailing edge, and is slidable onto the blade tip. Strips of a double-sided adhesive tape are attached onto either or both pressure and suction side surfaces of the blade adjacent the blade tip, or onto interior surfaces of the add-on component, the tape strips having a release liner on an opposite exposed side thereof. An extension tail is configured with the release liner that extends beyond the span-wise end of the add-on component when the add-on component is placed and held at a desired position on the blade. The add-on component is slid onto and maintained in position on the blade tip and, starting from the tape strip furthest from the separated trailing edge, extension tails of the respective tape strips are sequentially peeled through the separated trailing edge and away from the add-on component.

Abstract: A rotor blade assembly of a wind turbine includes an aerodynamic body having an inboard region and an outboard region. The inboard and outboard regions define a pressure side, a suction side, a leading edge, and a trailing edge. The inboard region includes a blade root, whereas the outboard region includes a blade tip. The outboard region also has a twist variation of less than plus or minus about 0.5 degrees (°) in order to reduce a rate of reduction in at least one of a chord length or a thickness of the rotor blade in the outboard region.

Abstract: A method for manufacturing a rotor blade panel of a wind turbine includes placing one or more fiber-reinforced outer skins into a mold of the rotor blade panel. The method also includes printing and depositing, via a computer numeric control (CNC) device, a plurality of rib members that form at least one three-dimensional (3-D) reinforcement grid structure onto an inner surface of the one or more fiber-reinforced outer skins. Further, the grid structure bonds to the one or more fiber-reinforced outer skins as the grid structure is deposited. Moreover, the method includes printing at least one additional feature into the grid structure.
