    Abstract: Rotor blade assemblies for wind turbines are provided. A rotor blade assembly includes a rotor blade. In some embodiments, the rotor blade assembly further includes a surface feature configured on an exterior surface of the rotor blade, the surface feature having an exterior mounting surface. At least a portion of the exterior mounting surface has a contour in an uninstalled state that is different from a curvature of the exterior surface of the rotor blade at a mount location of the surface feature on the rotor blade. In other embodiments, the rotor blade assembly further includes a seal member surrounding at least a portion of a perimeter of the surface feature. The seal member contacts and provides a transition between the exterior surface and the surface feature.

    Abstract: A system and associated method for detecting lighting strikes on a wind turbine uses a plurality of lightning strike conductors that are connected to any combination of the wind turbine components. A common ground cable is connected to the conductors and to a wind turbine grounding system. A sensor is operatively configured on the common ground cable to detect current flowing through the cable from a lightning strike incident on any one of the receptors, with the sensor producing a signal proportional to the intensity of the lightning strike.

    Abstract: A method and assembly for aligning airflow modifying elements on a rotor blade is disclosed. The airflow modifying assembly may be mounted onto a suction side surface or a pressure side surface of the rotor blade. Further, the airflow modifying assembly includes an alignment structure having a chord-wise extending face that may be fixed relative to the rotor blade at a predetermined position. The airflow modifying assembly further includes a first base having a root end, a tail end having an interconnecting profile, and a first plurality of airflow modifying elements. The root end is aligned with the chord-wise extending face such that the first base extends span-wise along the rotor blade. Additionally, the airflow modifying assembly includes at least one second base having a connector end with a complementary interconnecting profile and a plurality of airflow modifying elements, wherein the connector end is coupled to the tail end.
