Abstract
Pala de rotor (10) para una planta de energ¡a eolica, con un perfil aerodin mico que presenta un canto anterior (18) y un canto posterior (20). A los fines de disminuir las emisiones sonoras en plantas de energ¡a eolica, se acoda o curva la pala de rotor en su sector final (12), hacia el canto posterior de la pala de rotor, en el plano de la pala de rotor. Ello se basa en la comprobacion de que, en la punta de una pala de rotor que no se agudiza, la superficie de pala de rotor efectiva se mantiene invariable justamente en el sector exterior, en el cual su accion es m xima. Mediante el acodado o el curvado del sector final de la pala de rotor se desplaza hacia atr s el canto posterior en el sector final de la pala de rotor, de manera que el flujo en el canto posterior de la pala de rotor se desprende en el sector externo con un retardo temporal.
