Abstract[English]
A first aspect of the invention provides a pitch controlled wind turbine comprising a tower, a nacelle mounted on the tower, a hub mounted rotatably on the nacelle, and at least three wind turbine blades, wherein each wind turbine blade extends between a root end connected to the hub via a pitch mechanism, and a tip end, the wind turbine further comprising at least three blade connecting members, each blade comprising a first connection point and a second connection point, wherein each blade connecting member extends from a first connection point on one wind turbine blade towards a second connection point on a neighbouring wind turbine blade, where each connection point on a given wind turbine blade is arranged at a distance from the root end and at a distance from the tip end of the wind turbine blade and adjacent a leading edge of the wind turbine blade, and wherein each connecting member is independently moveable in two orthogonal directions at the respective first and second connection points to which it attaches.[French]
Un premier aspect de l'invention concerne une éolienne à pas variable comprenant une tour, une nacelle montée sur la tour, un moyeu monté rotatif sur la nacelle, et au moins trois pales d'éolienne ; chaque pale d'éolienne s'étend entre une extrémité de racine reliée au moyeu par l'intermédiaire d'un mécanisme de pas, et une extrémité de pointe ; l'éolienne comprend en outre au moins trois éléments de liaison de pale ; chaque pale comprend un premier point de liaison et un second point de liaison ; chaque élément de liaison de pale s'étend d'un premier point de liaison sur une pale d'éolienne vers un second point de liaison sur une pale d'éolienne voisine ; chaque point de liaison sur une pale d'éolienne donnée est disposé à une certaine distance de l'extrémité de racine et à une distance de l'extrémité de pointe de la pale d'éolienne et adjacent à un bord d'attaque de la pale d'éolienne ; et chaque élément de liaison est indépendamment mobile dans deux directions orthogonales au niveau des premier et second points de liaison respectifs auxquels il se fixe.
