Abstract

L'invention concerne une éolienne comprenant au moins une pale de rotor comprenant: un transmetteur conçu pour transmettre un signal de rayonnement électromagnétique (EM) présentant des caractéristiques dépendantes de l'espace; un récepteur conçu pour recevoir le signal de rayonnement EM, le récepteur étant situé sur la pale au niveau d'un emplacement extérieur par rapport au transmetteur et étant conçu de sorte qu'une déviation de la pale de rotor provoque un déplacement du récepteur par rapport au transmetteur; et un processeur conçu pour calculer une déviation de la pale de rotor sur la base des caractéristiques dépendantes de l'espace du signal de rayonnement EM reçu. L'invention concerne également un procédé de détermination de la déviation d'une pale d'un rotor d'éolienne pendant la rotation du rotor, le procédé comprenant: la transmission depuis une première position d'un signal de rayonnement électromagnétique (EM) présentant des caractéristiques dépendantes de l'espace; la réception du signal EM au niveau d'une seconde position, la seconde position étant située sur la pale au niveau d'un emplacement extérieur par rapport à la première position et étant conçue de sorte qu'une déviation de la pale de rotor provoque un déplacement de la seconde position par rapport à la première position; et le calcul de la déviation de la pale sur la base des caractéristiques dépendantes de l'espace du signal de rayonnement EM reçu.
