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).

La présente invention concerne une pale (1) pour un rotor d~aérogénérateur possédant un arbre de rotor sensiblement horizontal, ledit rotor doté d~un moyeu, comportant, vu dans un sens longitudinal sur un axe longitudinal (10) : une zone d~emplanture (2), la plus proche du moyeu ; une zone de profil aérodynamique (4), la plus éloignée du moyeu ; et une zone de transition (3) entre la zone d~emplanture (2) et la zone de profil aérodynamique (4). Vu dans le sens transversal, la pale (1) comporte un bord d~attaque (5) et un bord de fuite (6) ainsi qu~un plan de corde (K) qui se prolonge entre le bord d~attaque (5) et le bord de fuite (6) de la pale (1). Une zone de surface avec une pluralité de dentelures (7) et/ou de protubérances est réalisée dans au moins la zone d~emplanture (2), lesdites dentelures et/ou protubérances étant formées et dimensionnées pour améliorer le passage du vent sur la surface de la pale (1).
