Abstract

L'invention concerne une aube destinée au moulinet d'un aérogénérateur et permettant d'augmenter l'efficacité de production d'énergie à une vitesse de vent plutôt faible et d'empêcher une rotation excessive du moulinet tout en assurant une efficacité de production d'énergie donnée à une vitesse de vent plutôt élevée. Cette aube comprend un corps d'aube (22) d'une courbure donnée fixé rotatif à l'arbre rotatif du moulinet, ainsi qu'un élément auxiliaire (23) monté au niveau de l'extrémité arrière du corps d'aube dans le sens de rotation du corps d'aube de façon à se prolonger à partir de celui-ci. Ledit élément auxiliaire présente une première forme augmentant la courbure de l'aube et de la zone saillante de l'aube sur la surface rotative du moulinet. Lorsque la force du vent augmente, il peut se déformer à partir de cette première forme et prendre une seconde forme réduisant la courbure de l'ensemble de l'aube au même niveau que la courbure du corps d'aube. Lorsque la force du vent diminue, il reprend sa première forme.
