Abstract

Un álabe (10) de turbina eólica para un rotor de una turbina (2) eólica que tiene un eje de rotor sustancialmente horizontal, el rotor comprende un cubo (8) desde el cual el álabe de turbina eólica se extiende sustancialmente en una dirección radial cuando se monta al cubo (8), al álabe de turbina eólica se extiende en una dirección (r) longitudinal a lo largo de un eje de inclinación y que tiene un extremo (16) de punta y un extremo (14) de raíz así como álabe una longitud de álabe, el álabe de turbina eólica comprende además un contorno perfilado que incluye un lado de presión y un lado de succión, así como álabe un borde (18) de entrada y un borde (20) de salida con una cuerda que tiene una longitud de cuerda que se extiende entre estas, el contorno perfilado, cuando es impactado por un flujo de aire incidente genera un levantamiento, en donde el lado de succión del álabe de turbina eólica se suministra con una pluralidad de generadores de vórtice ubicados a lo largo de una línea (36) montante que tiene un punto (37A) de extremo próximo más cercano al extremo de raíz y un punto de extremo distante (37B) más cercano al extremo de punta, caracterizado porque la línea montante es una línea cóncava vista desde el borde de salida del álabe de turbina eólica, en donde el punto de extremo próximo se ubica en un intervalo de longitud de álabe de 0-0.12 L desde el extremo de la raíz y en una posición de cuerda relativa de 2%-20%, y en donde el punto de extremo distante se ubica en un intervalo de longitud de álabe de 0.2 L a 0.5 L desde el extremo de raíz y en una posición de cuerda relativa de 25%-75%.
