Abstract

L'invention concerne une pale de rotor pour une centrale électrique éolienne ainsi qu'une centrale électrique éolienne présentant un rotor équipé de telles pales de rotor. Le but de l'invention est de pallier aux désavantages mentionnés plus haut et de permettre un rendement total plus élevé. Pale de rotor d'une centrale électrique éolienne, pour laquelle la pale de rotor présente en particulier dans la zone centrale du rotor, appelée mainboard, un coefficient de glissement présentant, aux alentours de ± 2 % de l'angle d'attaque optimal, une valeur de plus de 80 % et préférentiellement de 90 % de la valeur maximum du coefficient de glissement.
