Abstract

Pala de rotor para una planta de energía eólica, con varios orificios dispuestos en el sector de la raíz de la pala de rotor y conformados esencialmente como orificios pasantes, los que se extienden esencialmente en forma transversal al eje longitudinal de la pala de rotor, pernos transversales incorporados en los orificios y elementos de tracción vinculables con los pernos transversales. Aquí, los elementos de tracción del estado de la técnica se extienden dentro de la raíz de la pala de rotor y debilitan entonces el material en este sector. A los fines de superar estas desventajas mediante una simplificación constructiva, la pala de rotor de acuerdo con la presente esta caracterizada por elementos de tracción que se extienden exteriormente a la raíz de la pala de rotor. Para ello, la presente se basa en la comprobación de que, con ello, el sector de la raíz de la pala de rotor es modificado aerodinámicamente en forma desfavorable pero no posee una influencia desfavorable en el comportamiento acústico y las demás propiedades de la planta, porque este sector está cubierto por el casquete del rotor (spinner) o se encuentra a lo menos en la pieza del rotor que gira más lentamente.
