    Abstract: A joint assembly for joining rotor blade segments of a wind turbine rotor blade includes a female structural member secured within a first rotor blade segment. The female structural member includes first bore holes on opposing sides thereof that are aligned in a chord-wise direction. Further, the joint assembly includes a male structural member extending longitudinally from an end face of a second rotor blade segment. As such, the male structural member is received within the female structural member of the first rotor blade segment such that the first and second rotor blade segments are aligned and connected. The male structural member includes second bore holes on opposing sides thereof. Further, the second bore holes are aligned with the first bore holes. Moreover, the joint assembly includes at least one chord-wise extending pin extending through the first and second bore holes so as to join the first and second rotor blade segments. In addition, the male structural member has a height that increases from a blade root of the rotor blade towards the at least one chord-wise extending pin.

    Abstract: Methods for joining surface features to wind turbine rotor blades are provided. A method includes providing the surface feature after forming of the rotor blade. The surface feature includes a thermoplastic resin. The formed rotor blade includes a plurality of blade components joined together to form an exterior surface defining a pressure side, a suction side, a leading edge, and a trailing edge each extending between a tip and a root. The formed rotor blade further includes a thermoplastic resin. The method further includes positioning the surface feature adjacent the exterior surface, and welding the thermoplastic resin of the surface feature and the thermoplastic resin of the formed rotor blade together.

    Abstract: A wind turbine rotor blade may generally include a blade root, a blade tip opposite the blade root and a body shell extending between the blade root and the blade tip. The body shell may include a pressure side and a suction side extending between a leading edge and a trailing edge and may define an outer shell surface. The rotor blade may also include a leading edge cap coupled to the body shell at the leading edge. The leading edge cap may be formed from a fiber-reinforced composite including an inner surface extending directly adjacent to the body shell along a portion of the outer shell surface and an outer surface opposite the inner surface. The fiber-reinforced composite may include a plurality of fibers surrounded by a thermoplastic resin material, with the thermoplastic resin material extending throughout the fiber reinforced composite from the inner surface to the outer surface.
