Abstract

Pala (5) de rotor de turbina eólica que comprende una disposición (20) de aleta, comprendiendo la pala (5) de rotor de turbina eólica un borde (109) de ataque, un borde (111) de salida y una cuerda (101) de referencia entre el borde (109) de ataque y el borde (111) de salida, en la que la disposición (20) de aleta comprende - una parte (21) de soporte, y - una parte (22) de aleta que puede moverse de manera pasiva con respecto a la parte de soporte y con respecto a un ángulo (β) entre una normal (34) de superficie de una superficie (41) de la parte (22) de aleta y la cuerda (101) de referencia, - posicionándose la parte (21) de soporte y la parte (22) de aleta en relación entre sí de modo que la parte (21) de soporte proporciona un límite al movimiento de la parte (22) de aleta, caracterizada porque en un primer estado la parte de aleta está en contacto con la parte de soporte y en un segundo estado se produce un espacio entre la parte de aleta y la parte de soporte.

31b de soporte.
En la figura 10(c) la parte 31c de soporte y la parte 32c de aleta están ambas conectadas al lado 113 de aspiración de la pala. La parte 31c de soporte consiste en material rígido y la parte 32c de aleta consiste en material flexible.
5 En la figura 10(d) la parte de borde de salida de la pala actúa como parte 31d de soporte. La parte 32d de aleta está conectada al lado 115 de presión de la pala y tiene las mismas características y propiedades que la parte 32b de aleta en la figura 10(b). La diferencia entre la parte 32b de aleta y la parte 32d de aleta es que en la figura 10(d) la parte 32d de aleta está conectada al lado 115 de presión de la pala de modo que la articulación 33 no está
10 directamente situada en el borde 111 de salida de la pala. En su lugar, la articulación 33 está situada en una posición en el lado 115 de presión de la pala.
Las figuras 11 y 12 muestran esquemáticamente una variante adicional de parte de una pala de rotor de turbina eólica de la invención en una vista en perspectiva y en sección. La figura 11 muestra la situación a baja velocidad de
15 viento, en la que la parte de aleta y la parte de soporte están en contacto entre sí. La figura 12 muestra la situación a alta velocidad de viento, en la que la parte 22e de aleta se ha movido lejos de la parte 21e de soporte. En la variante mostrada en las figuras 11 y 12 la parte 21e de soporte tiene la forma de una cresta.
La figura 13 muestra esquemáticamente la curva de potencias de una turbina eólica de la invención en comparación
20 con una turbina eólica convencional. El eje x muestra la velocidad de viento en m/s. El eje y muestra la potencia obtenida de la turbina eólica en W. La curva 29 de potencia de una turbina eólica con una pala convencional se compara con una curva 30 de potencia para una turbina eólica con una disposición de aleta de la invención. La curva 30 de potencia de la turbina eólica de la invención muestra una menor velocidad de viento de puesta en servicio y generalmente más potencia a bajas velocidades de viento en comparación con la curva 29 de potencia de
25 la pala de turbina eólica convencional. Esto significa que la turbina eólica de la invención puede funcionar a menor velocidad de viento que turbinas eólicas convencionales y produce más potencia a bajas velocidades de viento que turbinas eólicas convencionales.
