A BLADE FOR A WIND TURBINE AND A PRODUCTION METHOD THEREFORE

A blade (2) for a rotor (8) of a wind turbine (4), the blade (2) having a blade airfoil section (16) adapted for applying a lift force to the blade (2) and an inverted lift zone section (20) adapted for providing an inverted thrust component (24) for reducing the total thrust during wind load. Also...

Zusammenfassung:	A blade (2) for a rotor (8) of a wind turbine (4), the blade (2) having a blade airfoil section (16) adapted for applying a lift force to the blade (2) and an inverted lift zone section (20) adapted for providing an inverted thrust component (24) for reducing the total thrust during wind load. Also a production method is described. L'invention concerne une pale (2) pour un rotor (8) d'une turbine éolienne (4), la pale (2) ayant une section de profil de pale (16) adaptée pour exercer une force de portance sur la lame (2) et une section de zone de portance inverse (20) adaptée pour la mise en oeuvre d'un composant de poussée inverse (24) afin de réduire la poussée totale au cours d'une charge de vent. L'invention concerne aussi un procédé de production.
