    摘要： Rotor blade assemblies 100 for wind turbines 10 are provided. A rotor blade assembly 100 includes a rotor blade 16. In some embodiments, the rotor blade assembly 100 further includes a surface feature 102 configured on an exterior surface of the rotor blade 16, the surface feature 102 having an exterior mounting surface 122. At least a portion of the exterior mounting surface 122 has a contour in an uninstalled state that is different from a curvature of the exterior surface of the rotor blade 16 at a mount location of the surface feature 102 on the rotor blade 16. In other embodiments, the rotor blade assembly 100 further includes a seal member 16 surrounding at least a portion of a perimeter of the surface feature 102. The seal member 160 contacts and provides a transition between the exterior surface and the surface feature 102.

    摘要： A blade (1) for a wind turbine rotor having a substantially horizontal rotor shaft, said ro¬ tor comprising a hub, comprises, seen in longitudinal direction along a longitudinal axis (10), a root area (2) closest to the hub, an airfoil area (4) furthest away from the hub and a transition area (3) between the root area (2) and the airfoil area (4). Seen in transverse direction, the blade (1) comprises a leading edge (5) and a trailing edge (6) as well as a chord plane (K) extending between the leading edge (5) and the trailing edge (6) of the blade (1). A surface zone with a plurality of indentations (7) and/or pro¬ jections is provided in at least the root area (2), said indentations and/or projections be¬ ing formed and dimensioned to improve the wind flow across the surface of the blade (1).
