Abstract: A rotor blade for a wind turbine including a first blade segment and a second blade segment extending in opposite directions from a chord-wise joint. Each of the first and second blade segments include one or more shell members and an internal support structure. The internal support structure of the first blade segment includes a beam structure extending between a receiving end and a second end. The internal support structure of the second blade segment includes a receiving section that receives the receiving end of the beam structure of the first blade segment. The rotor blade further includes one or more connection locations where the first and second blade segments are secured together. Moreover, when the beam structure is received within the receiving section, a gap including a varying thickness is defined and maintained between the beam structure and the receiving section in a span-wise direction of the rotor blade.

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.
