Abstract: In one aspect, a method for installing a blade sock onto a rotor blade of a wind turbine may generally include positioning the blade sock adjacent to a blade tip of the rotor blade, wherein the blade sock comprises a sock strap forming a closed-shape. In addition, the method may include moving the blade sock relative to the rotor blade such that the blade tip is received within the closed-shape formed by the sock strap and moving the blade sock spanwise along the rotor blade towards a blade root of the rotor blade until the blade sock is positioned at an intermediate location defined between the blade root and the blade tip, wherein the sock strap is configured to fit tightly around an outer perimeter of the rotor blade at the intermediate location.

Abstract: A lift system for a rotor blade of a wind turbine includes a lifting device having a structural frame body having a root end and a tip end. The root end supports a root cradle and the tip end supports a tip cradle. The root and tip cradles each have a profile that corresponds to at least one exterior surface of the rotor blade so as to receive and support at least a portion of the rotor blade. Due to a shape of the rotor blade, when the rotor blade is installed in the lifting device and lifted uptower, the rotor blade can experience an asymmetric loading. Accordingly, the lift system also includes a variable airflow assembly coupled to tip end of the lifting device. The variable airflow assembly includes at least one surface moveable between a plurality of positions having varying resistances so as to counteract the asymmetric loading.

Abstract: A counterweight system for mounting a rotor blade on a balanced rotatable hub of a wind turbine is disclosed. The rotatable hub can have at least one blade root region configured to receive a blade root of the rotor blade, and also have a pitch system configured to rotate the rotor blade around a pitch axis. The counterweight system can have at least one support structure having a proximal end spaced apart from a distal end with the proximal end mountable to at least one blade root region of the rotatable hub. The at least one counterweight mass can be at least partially filled with fluid and coupled to the distal end of the at least one support structure. The at least one support structure can be arranged substantially parallel to the pitch axis such that the pitch system rotates the counterweight mass about the pitch axis.

Abstract: The present disclosure is directed to systems and methods for manufacturing a wind turbine rotor blade that can be easily lifted and lowered to and from a rotor installed atop a tower. The method includes providing a plurality of root inserts for a blade root of the blade and securing at least one cylindrical member to one of the root inserts such that the cylindrical member is substantially perpendicular with the root insert. The method also includes arranging the root inserts in a blade mold of the blade and forming a blade shell with the plurality of root inserts laminated therein. The method may further include securing at least one attachment component within each of the cylindrical members so as to provide an attachment location for a pulley cable used to lift and lower the rotor blade to and from the rotor installed atop the tower.

Abstract: A method for enabling servicing of a wind turbine rotor includes coupling a support cable to the blade root, the support cable extends from the blade root to a hub of the wind turbine. A lowering step lowers a rotor blade relative to the hub using the support cable so the rotor blade is spaced apart from the hub by an initial vertical distance. An installing step installs a rotor blade sling on the rotor, the rotor blade sling supports the rotor blade. Other steps are used for coupling the rotor blade to the rotor blade sling, lowering the rotor blade such that the rotor blade is spaced apart from the hub by a distance greater than the initial vertical distance, de-coupling the support cable from the blade root, and interposing a rotor servicing fixture between the rotor blade and hub. The rotor servicing fixture is configured to transport a rotor part.

Abstract: A method is provided for re-indexing a pitch bearing configured with a rotor blade of a wind turbine. A hoisting system is anchored within the rotor hub and includes a plurality of support elements connected to a drive system. The support elements are connected to the root flange of the rotor blade, and the rotor hub is rotated so that the rotor blade is in a vertical six o'clock position. The root flange is disconnected from the inner race such that the rotor blade is fully supported by the hoisting system. With the hoisting system, the rotor blade is lowered a predetermined distance from the hub and the pitch bearing is re-indexed to a position so as to engage a new set of pitch bearing teeth with a pitch drive that engages the pitch bearing.
