Abstract

Selon un premier aspect, la présente invention concerne une éolienne comprenant un rotor accouplé rotatif à une nacelle. Le rotor comprend un ensemble moyeu et une partie pale accouplée rotative à l'ensemble moyeu. La partie pale s'étend longitudinalement dans une direction d'envergure entre une extrémité intérieure et une extrémité extérieure. L'éolienne comprend en outre un capteur de déplacement fixé à l'ensemble moyeu et une pluralité de cibles de capteur fixées à la partie pale pour tourner par rapport au capteur de déplacement lorsque la partie pale est mise en rotation par rapport à l'ensemble moyeu. Le capteur de déplacement est agencé pour interagir avec chaque cible de capteur pour mesurer une distance entre le capteur de déplacement et la cible de capteur respective dans une direction de mesure sensiblement parallèle à la direction d'envergure de la partie de pale. En conséquence, le capteur de déplacement est agencé pour interagir avec la pluralité de cibles de capteur pour mesurer une pluralité de distances entre le capteur de déplacement et la pluralité de cibles de capteur lorsque la partie de pale est mise en rotation par rapport à l'ensemble moyeu.
