Abstract

La présente invention concerne une aube de rotor d'éolienne (1) pour éolienne qui peut être fixée sur un moyeu (2) de l'éolienne en un pas d'aube réglé au préalable de sorte que lorsqu'une charge est appliquée sur l'aube par le vent, l'aube traduit la charge en une poussée et un couple qui appliquent une force de rotation sur le moyeu autour de l'axe de rotation du moyeu. L'aube comprend une extrémité proximale (3) configurée pour être fixée au moyeu, une extrémité distale (5) à l'opposé de l'extrémité proximale, un côté face au vent qui s'étend depuis l'extrémité proximale jusqu'à l'extrémité distale et qui fait face à une direction à partir de laquelle la charge est appliquée et qui comprend au moins une section de coiffe de bord d'attaque (7), un côté sous le vent qui s'étend depuis l'extrémité proximale jusqu'à l'extrémité distale et qui est à l'opposé du côté sous le vent et qui comprend au moins une section de coiffe de bord de fuite (9), un partie centrale ou espar (11) supportant la charge qui s'étend essentiellement depuis l'extrémité proximale jusqu'à l'extrémité distale de l'aube et qui peut tourner autour de l'axe central de l'espar, ladite au moins une coiffe de bord d'attaque et ladite au moins une coiffe de bord de fuite étant fixées à l'espar central, où l'aube répond à des augmentations de la charge appliquées par flexion pour modifier continuellement le pas de l'aube desdites au moins une coiffe de bord d'attaque et de fuite de l'aube ; le pas de l'aube est soumis à un changement depuis une poussée positive vers une poussée négative le long de l'aube depuis son extrémité proximale vers son extrémité distale, de sorte que la poussée négative neutralise un partie de la poussée positive afin de réduire la poussée et le couple subis par l'aube en raison de la charge.
