Abstract

L'invention concerne une pale d'éolienne partiellement orientable, une cloison de décrochage étant placée au niveau de la jonction du système d'orientation partielle de la pale. Cette cloison de décrochage permet de séparer le flux d'air entre la section de pale intérieure et la section de pale extérieure et peut en outre être utilisé pour fermer l'interstice au niveau de la jonction du système d'orientation entre les deux sections de pale.
