Abstract

Una pala (16) de turbina eólica, comprendiendo dicha pala: una superficie (20) del lado de succión y una superficie (22) del lado de presión; una pluralidad de elementos vorticiales (32) configurados en al menos una de dichas superficies del lado de succión o del lado de presión; y teniendo dichos elementos vorticiales una cara (40) al viento inclinada hacia arriba y una cara (44) de deslizamiento inclinada hacia abajo, encontrándose dicha cara al viento y dicha cara de deslizamiento en una arista de extremos generalmente abiertos (42) con forma de U que define unos cuernos laterales (46), reduciéndose la altura de dichos cuernos laterales desde una porción más adelantada de dicha arista orientada en la dirección del flujo de viento hasta dicha superficie del lado de succión o dicha superficie del lado de presión, y en la que dichos elementos vorticiales (32) tienen una forma de duna de arena creciente con una cara convexa (58) al viento y una cara cóncava (60) de deslizamiento, comprendiendo dicha arista (42) con forma de U una forma de arco curvado continuamente.
