Abstract

Système de réduction de la traînée d’un véhicule à lame d’air frontale L’invention concerne un système de la réduction de la traînée d’un véhicule terrestre. Le véhicule (V) dispose d’un système (S) de réduction de la trainée comportant un conduit (C) d’une lame d’air. L’entrée d’air (E) du conduit (C) fait face à l’avant du véhicule et comporte une fente (FE) dont la hauteur (HE) est d’une dimension de quelques centimètres de hauteur. La sortie (S) du conduit (C) éjecte de l’air vers le haut suivant une fente de sortie (FS) dont la hauteur (HS) est d’une dimension de quelques millimètres à 1 cm, en ordre de grandeur 5 mm. L’entrée d’air (E) du conduit est implantée dans le compartiment moteur (CM). La sortie d’air (S) peut être implantée à la ligne (LC) du capot (A), sur le capot (CA), ou dans l’auvent (AV). Figure à publier avec l’abrégé : Fig. 8.The invention relates to a system for reducing the drag of a land vehicle. The vehicle (V) has a drag reduction system (S) comprising a conduit (C) for an air gap. The air inlet (E) of the duct (C) faces the front of the vehicle and has a slot (FE) whose height (HE) is a few centimeters high. The outlet (S) of the duct (C) ejects air upwards following an outlet slot (FS) whose height (HS) is of a dimension of a few millimeters to 1 cm, in order of magnitude 5 mm . The air inlet (E) of the duct is located in the engine compartment (CM). The air outlet (S) can be located at the line (LC) of the cover (A), on the cover (CA), or in the cowl (AV). Figure to be published with abstract: Fig. 8.
