Title (EN) A WIND TURBINE WITH A RING AIRFOIL SHROUD HAVING A FLAP
(FR) EOLIENNE POURVUE D'UNE ENVELOPPE ANNULAIRE À PROFIL AÉRODYNAMIQUE PRÉSENTANT UN VOLET
Abstract:
(EN) A ring airfoil with a voluminous leading edge region, an intermediate region, a trailing edge region including a flap. The ringed structural leading edge region combined with a rigid trailing edge region having intermediate discrete support portions extending therebetween provides sufficient rigidity to support the flap on the trailing edge region while using a membrane intermediate surface to form a portion of the intermediate region of the airfoil.
(FR) L'invention concerne un profil aérodynamique annulaire présentant une région de bord d'attaque volumineux, une région intermédiaire et une région de bord de fuite comprenant un volet. La structure annelée de la région de bord d'attaque combinée à la région de bord de fuite rigide ayant des parties supports discrets intermédiaires s'étendant entre les deux régions garantit une rigidité suffisante pour supporter le volet sur la région de bord de fuite tout en utilisant une surface intermédiaire de membrane pour former une partie de la région intermédiaire du profil aérodynamique.
