Abstract: A method for manufacturing a rotor blade panel of a wind turbine includes placing a mold of the rotor blade panel relative to a computer numeric control (CNC) device. The method also includes forming one or more fiber-reinforced outer skins in the mold. The method also includes printing and depositing, via the CNC device, printing and depositing, via the CNC device, a plurality of rib members that intersect to form at least one three-dimensional (3-D) reinforcement grid structure onto an inner surface of the one or more fiber-reinforced outer skins before the one or more fiber-reinforced outer skins have cooled from forming. Further, the grid structure bonds to the fiber-reinforced outer skin(s) as the structure is deposited. In addition, the plurality of rib members include, at least, a first rib member extending in a first direction and a second rib member extending in a different, second direction. Moreover, the first rib member has a varying height along a length thereof.

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: The present disclosure is directed methods for manufacturing spar caps for wind turbine rotor blades. In certain embodiments, the method includes forming an outer frame of the spar cap via at least one of three-dimensional (3D) pultrusion, thermoforming, or 3D printing. As such, the outer frame has a varying cross-section that corresponds to a varying cross-section of the rotor blade along a span thereof. The method also includes arranging a plurality of structural materials (e.g. layers of pultruded plates) within the pultruded outer frame of the spar cap and infusing the structural materials and the outer frame together via a resin material so as to form the spar cap. The resulting spar cap can then be easily incorporated into conventional rotor blade manufacturing processes and/or welded or bonded to an existing rotor blade.

Abstract: The present disclosure is directed to methods for manufacturing wind turbine rotor blades and components thereof, e.g. using 3D printing. In one embodiment, the method includes forming a rotor blade structure having a first surface and an opposing, second surface, the first and second surfaces being substantially flat. Another step includes printing a leading edge segment of the rotor blade onto the first surface, wherein heat from the printing bonds the leading edge segment to the first surface. The method also includes rotating the rotor blade structure having the leading edge segment attached thereto. A further step includes printing a trailing edge segment of the rotor blade onto the second surface, wherein heat from the printing bonds the trailing edge segment to the second surface. Another step includes securing one or more fiber-reinforced outer skins to the leading and trailing edge segments so as to complete the rotor blade.

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 method is provided for installing an add-on component to a surface of a wind turbine blade, as well as the blade with attached add-on component, and the add-on component as a stand-alone device. A slot is defined in one or both of the pressure side or suction side surfaces of the add-on component. The adhesive side of strips of a double-sided adhesive tape are attached onto either the surface of the wind turbine blade or an interior surface of the add-on component, the tape strips having a release liner on an opposite exposed side thereof. The tape strips are arranged longitudinally along one or both sides of the slot, and each strip has an extension tail that extends beyond an edge of the add-on component when component is held at a desired position against the surface of the wind turbine blade. The extension tails are pulled along the slot at an angle such that that release liner is removed through the slot along the length of the tape strip while maintaining the desired position of the add-on component against the surface of the wind turbine blade.
