Abstract

Ventilateur à pales flexible pour le refroidissement des véhicules automobiles. Il comprend des éléments de précontrainte agissant sur les faces d'extrados et d'intrados de chaque pale. L'élément de précontrainte d'extrados comprend une base qui s'étend transversalement au-delà de sa partie extérieure ainsi qu'au-delà de l'élément de précontrainte d'intrados. Il en résulte un accroissement de la fréquence de résonance et une diminution de l'amplitude des vibrations à la résonance ainsi qu'une meilleure configuration aérolique. Application aux circuits de refroidissement des moteurs à combustion interne de véhicule.
