Abstract
Pale de ventilateur comprenant un déflecteur d'air muni d'une surface supérieure généralement elliptique et d'une surface supérieure de la même forme. La pale de ventilateur a un rayon de courbure inférieur vers son bord d'attaque par rapport à un rayon de courbure plus élevé vers son bord de fuite. Lorsque des pales de ventilateur elliptiques sont montées sur un moyeu rotatif, elles peuvent déplacer de l'air à des taux d'efficacité significatifs.
