Title
(EN) ROTOR DEVICE AND CONTROL FOR WIND TURBINE
(FR) ROTOR ET COMMANDE POUR EOLIENNE
Abstract
(EN) A wind turbine with blades having a high lift-to-drag ratio is provided. A hydraulic or other control system is used to control cone angle, such as in response to flap moment. Pitch of blades is controlled, such as in relation to the blade flap angle. Teeter motion is controlled preferably as a function of teeter angular v elocity.
(FR) L'invention concerne une éolienne dont les pales (104a, 104b) possèdent une extrême finesse aérodynamique. On utilise un système de commande hydraulique, ou un système de commande d'un autre type, afin de commander par l'intermédiaire d'actionneurs (302a, 302b) l'angle de cône (214) des pales, notamment en réaction au battement. Le pas des pales est commandé en fonction de leur angle de battement. Le pivotement est commandé, de préférence, en fonction de la vitesse angulaire de pivotement.
