Abstract: The present disclosure is directed to a rotor blade assembly for a wind turbine that controls pitch bearing load distribution. The assembly includes a rotor blade having a body shell extending between a blade root and tip, a pitch bearing at an interface between the blade root and a hub of the wind turbine, and plurality of blade bolts coupling the blade root to the hub through the pitch bearing. The pitch bearing includes an outer bearing race and an inner bearing race rotatable relative to the outer race. Thus, in one embodiment, the blade bolts couple the blade root to the hub through the inner race of the pitch bearing. Further, each of the blade bolts has a first end and a second end defining a length therebetween and at least two of the blade bolts have varying lengths so as to distribute loads experienced by the pitch bearing.

Abstract: In one aspect, a method for manufacturing a spar cap for a wind turbine rotor blade may generally include stacking a plurality of plates together to form a plate assembly, wherein each of the plates is formed from a fiber-reinforced composite including a plurality of fibers surrounded by a thermoplastic resin material. The method may also include positioning the plate assembly relative to a mold defining a mold surface, wherein the mold surface is shaped so as to correspond to at least one blade parameter of the wind turbine rotor blade. In addition, the method may include applying pressure to the plate assembly via the mold such that at least a portion of the plate assembly conforms to the shape of the mold surface.
