Abstract: Rotor blades for a wind turbines include a structural support member disposed internal the rotor blade that extends for at least a portion of a rotor blade span length and an airfoil structure supported by the structural support member, the airfoil structure comprising a shell portion and at least one load-transferring exterior panel. The shell portion and the at least one load-transferring exterior panel combine to form an aerodynamic profile comprising a leading edge opposite a trailing edge and a pressure side opposite a suction side. Moreover, the shell portion and the at least one load-transferring exterior panel are independently connected to the structural support member.

Abstract: A method is provided for servicing a jointed rotor blade of a wind turbine. The jointed rotor blade is positioned in a six o'clock position and a blade tip support element is secured to a tip section of the jointed rotor blade. A lift-support element is secured at a mounting location above the blade tip support element. A lifting line is coupled between the lift-support element and the blade tip support element. The tip section is separated from the root section of the jointed rotor blade such that the tip section is suspended above a support surface of the wind turbine via the blade tip support element and the lifting line. The tip section of the jointed rotor blade is serviced.

Abstract: A spar cap assembly for a jointed rotor blade of a wind turbine includes a root spar cap assembly and a tip spar cap assembly. The root spar cap assembly includes a root tensile spar cap and a root compressive spar cap, and is formed from a first composite material. The tip spar cap assembly includes a tip tensile spar cap and a tip compressive spar cap, and is formed from a second composite material that is different from the first composite material. The thickness of a joining end of the root tensile spar cap is different from the thickness of a joining end of the tip tensile spar cap, and the thickness of a joining end of the root compressive spar cap is different from the thickness of a joining end of the tip compressive spar cap.
