    Abstract: A system and method for mounting a component to an internal web of a wind turbine blade includes, at a first mounting location on the internal web, at least one through-hole defined through the internal web. A bushing is located within the through-hole and is encased within an adhesive applied between the bushing and a wall of the through-hole. A plate is attached to each of the opposite panels of the internal web at the mounting location against an end face of the bushing, with each plate having a hole therein that is aligned with the through-hole. For mounting the component at the mounting location, a bolt is passed completely through the plates and bushing for attachment of a frame of the component to one of the plates.

    Abstract: The present disclosure is directed to a system and method for securing a lightning protection cable (e.g. a conductor) of a lightning protection system within a wind turbine rotor blade. The lightning protection system includes a plurality of lightning receptors configured along either or both of the pressure or suction sides of the rotor blade. The lightning receptors are connected via the conductor so as to form a conductive circuit. Further, a cover assembly defining a passageway therethrough is configured to receive at least a portion of the conductor along a length thereof. Thus, the cover assembly can be secured to an inner surface of the internal cavity so as to maintain a location of the conductor. Accordingly, the conductor is free to move within the cover assembly since the wire is not directly attached to the rotor blade.

    Abstract translation: 本公开涉及用于将雷电防护系统的防雷电缆（例如，导体）固定在风力涡轮机转子叶片内的系统和方法。 雷电保护系统包括沿转子叶片的压力或吸力侧中的任一者或两者配置的多个闪电接收器。 雷电接收器经由导体连接以形成导电电路。 此外，限定穿过其中的通道的盖组件被配置为沿其长度容纳导体的至少一部分。 因此，盖组件可以固定到内腔的内表面，以便保持导体的位置。 因此，由于导线不直接附接到转子叶片，导体可以在盖组件内自由移动。

    Abstract: In one aspect, a rotor blade for a wind turbine includes a body extending between a root end and a tip end. The body may include a root portion extending from the root end. The root portion may include an inner surface defining an inner circumference. In addition, the rotor blade may include a root stiffener disposed at least partially within the root portion of the body. The root stiffener may include a plurality of arms extending radially from the inner surface and may be configured to extend circumferentially around only a portion of the inner circumference of the root portion.

    Abstract: A rotor blade assembly for a wind turbine includes a pressure side and a suction side extending between a leading edge and a trailing edge. A generally cylindrical blade root section has a flush root end configured to attach the rotor blade assembly to a hub. A plurality of span-wise extending root inserts are disposed around and molded into the cylindrical blade root section, with each root insert having an end face and defining an internally threaded bore configured for receipt of a bolt member for attaching the rotor blade assembly to the hub. A metallic flange is disposed at an end of one of the root inserts. The metallic flange is flush with the end faces of adjacent root inserts such that the metallic flange and end faces of the root inserts lie in a common flush plane of the root end.

The assembly also includes a plurality of first bolt joints located at a first end of the beam structure for connecting with the receiving section of the blade root segment. The assembly also includes a lightning protection system with at least one lightning receptor coupled to a lightning receptor cable. The lightning receptor cable is routed from the blade tip to each of the plurality of first bolt joints and to the blade root.
