Abstract

La présente invention concerne une pale d'éolienne possédant un bord de fuite dentelé. Des aubes directrices d'écoulement sont disposées sur les dentelures, de manière à empêcher un écoulement latéral sur les bords des dentelures, qui sont de préférence disposées de manière incidente par rapport à l'écoulement sur la pale d'éolienne. Les aubes peuvent être formées d'un seul tenant avec les dentelures, ou attachées aux dentelures existantes en tant que solution de rattrapage. Les dentelures dotées des aubes peuvent être fournies sous la forme d'un panneau de bord de fuite pour une fixation au bord de fuite d'une pale d'éolienne existante.
