Abstract[English]
In a first aspect of the present invention there is provided a wind turbine comprising a tower, a nacelle mounted on the tower, and a rotor mounted to the nacelle. The rotor comprises a hub and at least three wind turbine blades. Each blade extends between a root and a tip. Each blade further comprises a connection point located between the root and the tip. The wind turbine further comprises a plurality of blade connecting members, each blade connecting member being connected between corresponding connection points of a pair of wind turbine blades. The wind turbine further comprises a tensioning system for adjusting the tension in each blade connecting member. The tensioning system comprises a plurality of linear actuators, each linear actuator being coupled between the hub and a respective blade connecting member. Each linear actuator is configured to adjust the tension in the blade connecting member.[French]
Selon un premier aspect, la présente invention concerne une éolienne comprenant une tour, une nacelle montée sur la tour, et un rotor monté sur la nacelle. Le rotor comprend un moyeu et au moins trois pales d'éolienne. Chaque pale s'étend entre une racine et une pointe. Chaque pale comprend en outre un point de liaison situé entre la racine et la pointe. L'éolienne comprend en outre une pluralité d'éléments de liaison de pale dont chacun est relié entre des points de liaison correspondants d'une paire de pales d'éolienne. L'éolienne comprend en outre un système de tension pour ajuster la tension dans chaque élément de liaison de pale. Le système de tension comprend une pluralité d'actionneurs linéaires dont chacun est couplé entre le moyeu et un élément de liaison de pale respectif. Chaque actionneur linéaire est conçu pour ajuster la tension dans l'élément de liaison de pale.
