Abstract
Una punta de pala para una pala de rotor, con un perfil aerodinámico que presenta un lado de succion y un lado de presion, en la cual la punta de pala de rotor, en su sector final, está acodada o curvada en la direccion a su lado de presion. A los fines de disminuir aun más las emisiones sonoras en plantas de energía eolica, la punta de pala de rotor está conformada de modo que el ôsector externoö va disminuyendo de seccion transversal. Esta conformacion de la punta de pala de rotor se basa sobre la comprobacion de que por medio de la profundidad decreciente de la pala se produce un flujo circundante disminuido, dado que su energía se distribuye previamente en las turbulencias del canto posterior pero disminuye simultáneamente la superficie de pala de rotor efectiva. Mediante el curvado de la punta de pala de rotor permanece optima hasta la punta de pala de rotor curvada la profundidad efectiva de la pala de rotor.
