Abstract: An aerodynamic hub assembly for a wind turbine is disclosed. The hub assembly may include a hub extension, a rotor blade having a blade root and a blade tip, and a hub airfoil section mounted at least partially over the hub extension. The hub airfoil section may be fixed relative to the rotor blade or may be configured to rotate about a common pitch axis with the rotor blade. The hub extension may be connected to and extend radially from a center of the hub assembly. Further, the hub assembly may include a pitch bearing having an inner race and an outer race, wherein the pitch bearing may be coupled between the hub extension and the blade root. Additionally, the hub assembly may also include an aerodynamically-shaped spinner, wherein the spinner may house at least a portion of a root structure extending radially from the center of the hub assembly.

Abstract: A drivetrain assembly for a wind turbine includes a main shaft, a bearing operatively coupled to an end of the main shaft, a bearing housing surrounding the bearing, and a gearbox having, at least, a ring gear. The ring gear is positioned adjacent to the bearing housing and includes an outer circumferential surface. The drivetrain assembly also includes at least one flexible member arranged at an interface between the bearing housing and the ring gear. As such, the flexible member(s) is configured to reduce vibrations generated by the gearbox.
