Abstract

Una pala de rotor para una instalacion de energía eolica, así como la misma instalacion de energía eolica, cuya orientacion relativa a la direccion del viento es regulada en funcion de la intensidad del viento. Se optimiza el perfil aerodinámico de la pala para aumentar su eficiencia a distintos ángulos de incidencia del viento y se elimina el ôagujero de fugaö en el centro del rotor salvo para vientos de baja intensidad. La pala de rotor presenta un espesor del respaldo en el intervalo de 15% a 40%, preferentemente de 23% a 28%, y el mayor espesor del perfil está entre 20% y 45%, preferentemente entre 32% y 36%.
