Abstract

L'invention concerne une pale d'éolienne partiellement orientable, un matériau de remplissage aérodynamique étant placé au niveau de l'articulation du système d'orientation. Ce matériau de remplissage permet de réduire les pertes d'extrémité au niveau de l'articulation, ce qui améliore l'efficacité de la pale d'éolienne. Le matériau de remplissage peut être un matériau gonflable ou élastique, tel que du caoutchouc ou de la mousse, ou peut être une coque appliquée au niveau de l'articulation.
