Abstract

L'invention concerne une structure permettant d'améliorer efficacement la consommation de carburant d'un corps en mouvement, tel qu'un véhicule en mouvement. Cette structure comprend un arbre de ventilateur (23) orienté globalement de façon perpendiculaire par rapport au sens de déplacement (X) du corps en mouvement (1), des ventilateurs (21) fixés à l'arbre de ventilateur (23) et mettant ce dernier en rotation sous l'action d'un vent de face, des arbres de transmission (43) situés globalement en parallèle par rapport au sens de déplacement (X), des mécanismes de transmission (30) reliant l'arbre de ventilateur (23) aux arbres de transmission (43) et transmettant la force de rotation de l'arbre de ventilateur (23) aux arbres de transmission (43), et des hélices (41) fixées sur les arbres de transmission (43).
