Title
(EN) DEVICE FOR CONTROLLING AERODYNAMIC TURBULENCE OCCURRING AT THE WALLS OF MOVING MOTOR VEHICLES, AND METHOD USING SAME
(FR) DISPOSITIF DE CONTRÔLE D'UNE STRUCTURE TOURBILLONNAIRE DE SILLAGE APPARAISSANT AUX PAROIS DE VÉHICULES AUTOMOBILES EN MOUVEMENT, ET PROCÉDÉ DE MISE EN OEUVRE D'UN TEL DISPOSITIF
Abstract
(EN)
The invention concerns a device for controlling aerodynamic turbulence occurring at the walls of moving motor vehicles, said aerodynamic turbulence extending longitudinally about a longitudinal axis (5). The invention is characterized in that it comprises a longitudinal element (6) having a rotational symmetry about its longitudinal axis, and in that it comprises means (8) for adjusting the length and the position of the longitudinal element so as to substantially align the axis of the element with the axis of said aerodynamic turbulence and to adjust the length of the element such that the length is sufficient to break up and/or blow up the aerodynamic turbulence. The invention also concerns a method using said device.
(FR)
L'invention concerne un dispositif de contrôle d'une structure tourbillonnaire de sillage apparaissant aux parois de véhicules automobiles en mouvement, ladite structure tourbillonnaire s'étendant longitudinalement autour d'un axe longitudinal (5), caractérisé en ce qu'il comprend un élément longitudinal (6) présentant une symétrie de révolution autour de son axe longitudinal, et en ce qu'il comprend des moyens de réglage (8) de la longueur et de la position de l'élément longitudinal afin d'aligner sensiblement l'axe de l'élément avec l'axe de ladite structure tourbillonnaire et de régler la longueur de l'élément afin que sa longueur soit suffisante pour provoquer la déstructuration et/ou l'éclatement de la structure tourbillonnaire. L'invention concerne également un procédé de mise en oeuvre d'un tel dispositif.
