Abstract

L'invention porte sur une pale de ventilateur qui comporte une extrémité d'emplanture, une région pale et une région de transition, chacune de l'extrémité d'emplanture et de la région pale comportant un profil unique, et la région de transition comportant un profil qui forme la transition entre le profil de l'extrémité d'emplanture et le profil de la région pale. Le profil d'extrémité d'emplanture comporte une surface supérieure sensiblement convexe, un secteur en dôme sensiblement concave et des reliefs pour permettre à l'extrémité d'emplanture de se coupler à un prolongement de moyeu de ventilateur de forme similaire. Le profil de la région pale comporte une surface supérieure sensiblement convexe et une surface inférieure qui se terminent à un bord d'attaque et à un bord de fuite. La région pale est en pente montante le long de la longueur de la région pale et se termine par un bout incurvé.
