Wind turbine rotor blade assembly with surface features

A rotor blade assembly for a wind turbine, the rotor blade assembly comprising:

• a rotor blade having exterior surfaces defining a pressure side, a suction side, a leading edge, and a trailing edge each extending between a tip and a root, the rotor blade further defining a span and a chord;
• a surface feature configured on an exterior surface of the rotor blade, the surface feature having an exterior mounting surface, the exterior mounting surface having a contour with a radius of curvature in an uninstalled state less than a radius of curvature of a contour of the exterior surface of the rotor blade at a mount location of the surface feature on the rotor blade;
• and
• a plurality of attachment features configured to secure the surface feature to the exterior surface of the rotor blade, the plurality of attachment features comprising a first attachment feature proximate a perimeter of the surface feature and a separate, second attachment feature spaced from the perimeter of the surface feature relative to the first attachment feature, the first and second attachment features comprising a bond media.

• a surface feature configured on an exterior surface of the rotor blade, the surface feature having an exterior mounting surface defining a perimeter, wherein the exterior mounting surface in the uninstalled state is concave and the exterior surface of the rotor blade is convex;
• at least one attachment feature configure within the perimeter and connecting the surface feature to the rotor blade;
• and
• a seal member surrounding at least a portion of a perimeter of the surface feature and the attachment feature, the seal member contacting and providing a transition between the exterior surface and the surface feature.
