    Abstract: The present disclosure is directed to a fastener retention assembly for a wind turbine rotor. The fastener retention assembly includes a rotor hub and a pitch bearing race coupled to the rotor hub. One of the pitch bearing race or the rotor hub defines an annular slot. The pitch bearing race and the rotor hub further defines a plurality of passages extending from the slot through the pitch bearing race and the rotor hub. The fastener retention assembly also includes a plurality of fasteners coupling the rotor hub and the pitch bearing race. Each of the plurality of fasteners is at least partially positioned within the slot and one of the plurality of passages. The fastener retention assembly further includes a retaining ring partially positioned within the slot to retain the plurality of fasteners within the plurality of passages.

    Abstract: A wye ring centering system is provided. The system includes a plurality of rollers configured for contacting a wye ring, and a plurality of mounting fasteners configured for supporting the plurality of rollers. Each of the mounting fasteners is configured to pass through a fan hub. The plurality of rollers and the plurality of mounting fasteners are distributed at substantially equal intervals around the fan hub. The wye ring is placed over the plurality of rollers to center the wye ring around a shaft.

    Abstract: A method for removing a rotor blade from a wind turbine may generally include installing a blade sock around an outer perimeter of the rotor blade, coupling a support cable to the blade root, lowering the rotor blade relative to the hub using the support cable, coupling at least one pulley cable between the rotor blade and a winch using at least one pulley, moving the pulley cable relative to the pulley to lower the rotor blade relative to the hub, applying a force through the blade sock as the pulley cable is moved relative to the pulley in order to control an orientation of the rotor blade and further lowering the rotor blade to a location on or adjacent to the support surface.

    Abstract: A method and system are provided for cooling a heat-exchanger in a wind turbine that has an electric generator with a cooling air flow directed therethrough. Effluent cooling air flow from the electric generator is directed into an air ejector pump and acts as motive air through the air ejector pump. Cold air is drawn into the air ejector pump by the vacuum generated by the motive air moving through the air ejector pump. The heat exchanger is disposed in-line with the cold air flow so that the cold air is drawn through the heat-exchanger, removes heat from the fluid circulated through the heat-exchanger, and becomes heated air that is combined with the motive air and discharged from the nacelle.
