Abstract

Ce système de mise en mouvement d'air (4) comprend une hélice centrifuge (7) mobile en rotation autour d'un axe de rotation (A), l'hélice centrifuge (7) comprenant une pluralité de pales d'hélice (8) configurées pour générer un flux d'air, et une plaque de base (9) comprenant une première face de plaque à partir de laquelle font saillie les pales d'hélice (8), et une deuxième face de plaque opposée à la première face de plaque ; et un moteur d'entraînement (18) configuré pour entraîner en rotation l'hélice centrifuge (7) autour de l'axe de rotation (A). La plaque de base (9) comprend une pluralité d'ondulations qui sont circulaires et concentriques, la pluralité d'ondulations comprenant au moins une ondulation concave (14.1) et au moins une ondulation convexe (14.2).
