Abstract

Des modes de réalisation de l'invention se rapportent à un système de rotor, particulièrement destiné à être utilisé dans un système de générateur d'éolienne. Un support (11), auquel sont accouplés des premier et second éléments rotatifs (12, 13), est prévu, les éléments rotatifs pouvant tourner autour d'un axe commun. Une ou plusieurs pales flexibles (14, 15) comportant au moins deux extrémités sont prévues, une extrémité étant montée sur le premier élément rotatif et une autre extrémité étant montée sur le second élément rotatif, de sorte qu'elles puissent tourner autour de l'axe commun. Un moyen d'actionnement est prévu, conçu pour amener les extrémités de chaque pale à se rapprocher l'une de l'autre grâce au déplacement d'au moins un des éléments rotatifs le long de l'axe commun. Les premier et second éléments rotatifs sont conçus pour tourner l'un par rapport à l'autre, ladite rotation permettant aux pales flexibles de s'enrouler autour d'un axe.
