Abstract
La presente invencion se refiere a un aspa de rotor para una planta de energia eolica, con un perfil aerodinamico que tiene un borde de ataque del aspa de rotor y un borde posterior del aspa del rotor. La presente invencion se refiere ademas a una punta de aspa de rotor para un aspa de rotor con un perfil aerodinamico que tiene un lado de presion y un lado de succion, siendo que la seccion extrema de la punta del aspa del rotor tiene un doblez o inflexion en direccion al lado de presion del aspa de rotor. Para disminuir aun mas las emisiones sonoras de las plantas de energia eolica la seccion extrema del aspa de rotor se encuentra doblada o curvada en el plano del aspa de rotor en direccion al borde posterior del aspa de rotor. La invencion se funda en el conocimiento de que en un aspa de rotor cuya punta no es puntiaguda la superficie efectiva del aspa de rotor se mantiene sin cambio justamente en la seccion externa en la que el efecto es mayor. Sin embargo, mediante el doblez o curvatura de la seccion extrema del aspa de rotor, el borde posterior de la seccion extrema del aspa de rotor se desplaza hacia atras, de manera que la corriente en el borde posterior del aspa de rotor se desprende del area externa con un retardo. En una modalidad alternativa es posible perfeccionar una punta de aspa de rotor de manera que la "seccion externa" sea puntiaguda. Esta configuracion de la punta del aspa del rotor se funda en el conocimiento de que la disminucion de la profundidad del aspa resulta en una reduccion de la corriente de aire alrededor de la punta del aspa, en vista de que su energia se distribuye antes sobre los vortices del borde posterior, pero tambien se reduce simultaneamente la superficie efectiva del aspa de rotor. Mediante la inflexion de la punta del aspa de rotor se mantienen optima la profundidad efectiva del aspa de rotor hasta la punta acodada del aspa de rotor.
