    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.

    Abstract: The present subject matter is directed to a rotor blade assembly having a rotor blade with a blade tip segment having a blade tip and a blade root segment having a blade root. The blade segments extend in opposite directions from a chord-wise joint. The blade tip segment includes a beam structure extending lengthways that structurally connects with the blade root segment via a receiving section. 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.

    Abstract: A blade insert for coupling a first blade segment to a second blade segment is disclosed. The blade insert may include an aerodynamic body extending between a first end configured to be coupled to the first blade segment and a second end configured to be coupled to the second blade segment. The aerodynamic body may include a pressure side and a suction side extending between a leading edge and a trailing edge. In addition, the aerodynamic body may define a chord, wherein the chord at the first end is substantially equal to the chord at the second end.
