Abstract

Système de ventilation (10) pour moteur, notamment pour moteur de véhicule automobile, comprenant un ventilateur comportant une hélice (14) munie d’un moyeu (20), d’une virole (18) et d’une pluralité de pales principales (22), la pluralité de pales principales (22) étant réparties angulairement autour de la virole (18) et s’étendant entre le moyeu (20) et la virole (18), chaque pale principale (22) étant séparée de la pale principale (22) suivante par un espace intermédiaire (23),dans lequel au moins une pale secondaire (40, 40’) est disposée dans au moins l’un des espaces intermédiaires (23), la au moins une pale secondaire (40, 40’) comprenant une première extrémité (47) fixée à la virole (18) et une deuxième extrémité (49) libre, la au moins une pale secondaire (40, 40’) ayant un profil aérodynamique. Figure pour l’abrégé : Fig. 1Ventilation system (10) for an engine, in particular for a motor vehicle engine, comprising a fan comprising a propeller (14) provided with a hub (20), a shroud (18) and a plurality of main blades ( 22), the plurality of main blades (22) being angularly distributed around the shroud (18) and extending between the hub (20) and the shroud (18), each main blade (22) being separated from the main (22) following through an intermediate space (23), in which at least one secondary blade (40, 40') is arranged in at least one of the intermediate spaces (23), the at least one secondary blade (40, 40 ') comprising a first end (47) fixed to the shroud (18) and a second end (49) free, the at least one secondary blade (40, 40') having an aerodynamic profile. Figure for abstract: Fig. 1
