Abstract: The present disclosure is directed to a rotor blade assembly for a wind turbine. The rotor blade assembly includes a rotor blade having a blade root section and a rigid ring insert. The rotor blade has pressure and suction sides extending between leading and trailing edges. The blade root section includes an end face configured to attach the rotor blade assembly to a hub. Further, the blade root section includes a span-wise end portion defined by inner and outer circumferential components separated by a radial gap. The radial gap includes a first laminate material embedded between the inner and outer circumferential components at a first span-wise depth and a second laminate material embedded between the inner and outer circumferential components at a second span-wise depth. Thus, the rigid ring insert is disposed in the radial gap and embedded between the first and second laminate materials.

Abstract: The present subject matter is directed to a spacer assembly for a bearing of a wind turbine and/or a bearing assembly for a wind turbine. The bearing assembly includes an outer race, an inner race rotatable relative to the outer race, a plurality of roller elements positioned between the inner and outer race, and a plurality of load-bearing spacers configured between the roller elements. Each of the spacers includes a spacer portion and an extension portion. Thus, each of the spacers is arranged to contact adjacent spacers within the bearing assembly via the extension portion such that the extension portions of the spacers are configured to transfer loads experienced by the bearing assembly rather than the loads passing through the roller elements.

Abstract: The present invention is directed to a rotor blade assembly for a wind turbine. The rotor blade assembly includes a rotor blade extending from a blade root to a blade tip. The rotor blade has a pressure side surface and a suction side surface. The pressure side surface and the suction side surface each extend between a leading edge and a trailing edge. The assembly also includes a blade root extension configured to attach to one of the pressure side surface or the suction side surface of the rotor blade adjacent to the blade root. The blade root extension includes at least one blade fence and at least one airflow modifying element. The blade fence extends between a proximal end and a distal end in a chord-wise direction. The proximal end is configured to attach to the rotor blade such that the distal end remains free and spaced apart from the rotor blade. The airflow modifying element is configured at the proximal end of the blade fence. As such, the blade root extension is configured to improve aerodynamic performance of the rotor blade.
