Abstract
Pala de rotor (10) de un aplanta de energía eólica, con un acople de pala de rotor para conectarla al cubo (12) del rotor de una planta de energía eólica y una punta (13) de la pala de rotor que se encuentra en el extremo opuesto de la pala de rotor (10). A los fines de dar a conocer una pala de rotor (10) mediante la cual se puede detectar con medios sencillos una flexión, está tendido a lo menos un conductor eléctrico (20, 21, 22, 23, 24, 26, 28) a lo largo de la pala de rotor (10), para lo cual el conductor eléctrico (20, 21, 22, 23, 24, 26, 28) comienza en el acople de la pala de rotor, se extiende en la dirección longitudinal de la pala de rotor y retorna al acople de la pala de rotor, estando previsto un detector (16) que determina la resistencia eléctrica del conductor (20, 21, 22, 23, 24, 26, 28)y está conectado con un dispositivo de procesamiento que evalúa la resistencia eléctrica. Para ello, la presente se basa sobre la comprobación de que una flexión de la pala de rotor conduce a una elongación de la estructura portante y que tal elongación, transmitida a un conductor eléctrico, conduce a una variación de la resistencia eléctrica del conductor, a partir de la cual se puede deducir la flexión de la pala de rotor, dado que la variación de la resistencia es proporcional a la elongación del conductor y la misma a su vez proporcional a la flexión de la pala de rotor.
