发明名称 Wind turbine rotor blade assembly with surface features
摘要 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.

主权项 1. 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 defining a perimeter of the surface feature, at least a portion of the exterior mounting surface having a contour in an uninstalled state different from a contour of the exterior surface of the rotor blade at a mount location of the surface feature on the rotor blade; a plurality of attachment features configured within the perimeter of the surface feature and connecting the surface feature to the rotor blade, the plurality of attachment features comprising, at least, a first attachment feature proximate the 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; and a seal member surrounding at least a portion of the 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.
