Abstract

L'invention concerne les ventilateurs hélicoides à enveloppe dont la roue a un coefficient de pression élevé et crée donc une pression de giration importante. La roue est suivie d'un aubage fixe comportant au moins trois aubes planes à bord d'attaque incline sur l'axe de la machine. Un tel ventilateur trouve des applications dans tout le domaine d'utilisation des turbo-machines hélicoides à coefficient de pression élevé, que ce soit en ventilation en conditionnement de l'air ou pour obtenir une poussée ou une sustentation.
