Abstract: The present disclosure is directed to a rotor blade that includes a shell defining an interior cavity. The rotor blade also includes exterior surfaces defining a pressure side, a suction side, a leading edge, and a trailing edge. Each of the pressure side, the suction side, the leading edge, and the trailing edge extends between a tip and a root. The shell defines a span and a chord. A shear web is positioned in the interior cavity and coupled to the shell. The shear web includes a lattice structure.

Abstract: A rotor blade segment of a wind turbine includes a seamless leading edge surface. A method of manufacturing a rotor blade segment of a wind turbine, the rotor blade segment having a seamless leading edge surface, includes forming an outer skin of the rotor blade segment. The outer skin defines a continuous outer surface. The continuous outer surface includes a pressure side surface extending between a pressure side aft edge and a pressure side forward edge, a suction side surface extending between a suction side forward edge and a suction side aft edge, and the seamless leading edge surface extends between the pressure side forward edge and the suction side forward edge. After folding the outer skin, the pressure side surface is positioned opposite the suction side surface and the pressure side aft edge is proximate the suction side aft edge.

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.

Abstract: The present disclosure is directed to an apparatus and method for manufacturing a composite component. The apparatus includes a mold onto which the composite component is formed. The mold is disposed within a grid defined by a first axis and a second axis. The apparatus further includes a first frame assembly disposed above the mold and a plurality of machine heads coupled to the first frame assembly within the grid in an adjacent arrangement along the first axis. At least one of the mold or the plurality of machine heads is moveable along the first axis, the second axis, or both. At least one of the machine heads of the plurality of machine heads is moveable independently of one another along a third axis. A second frame assembly is moveable above the mold along the first axis, the second axis, or both. The second frame assembly includes a holding device. The holding device affixes to and releases from an outer skin to place and displace the outer skin at the mold.

Abstract: A method and mold assembly for manufacturing a rotor blade component of a wind turbine is disclosed. The mold assembly includes a mold body that is divided into a plurality of mold zones, with each mold zone having a sensor for sensing a temperature thereof. Further, a composite material schedule is provided for each of the mold zones. Thus, the method includes placing composite material onto the mold body according to the composite material schedule and supplying a resin material to each mold zone of the mold body. The method also includes implementing a cure cycle for the component that includes supplying heat to each of the mold zones, continuously receiving signals from the sensors from the mold zones, and dynamically controlling via machine learning the supplied heat to each mold zone based on the sensor signals and the composite material schedule.

Abstract: The present disclosure is directed to a rotor blade assembly for a wind turbine having a first rotor blade segment with a first spar cap segment and a second rotor blade segment with a second spar cap segment. The first and second spar cap segments are arranged together at an interface and are constructed of a composite material. Further, the rotor blade assembly includes a joint assembly at the interface of the first and second spar cap segments. The joint assembly is constructed of a first metal joint secured to the first spar cap segment and a second metal joint secured to second spar cap segment. Moreover, the first and second metal joints are welded together at a weld area.
