[0007] FIG. 2 shows the first positioning of the car (4) for measuring its weight and calculating the aerodynamic coefficient of drag coefficient and the range coefficient and also for visualizing the current lines by the digital camera (7).
[0008] Les 4 roues de la voiture sont placées sur les 4 capteurs de force (8) pour mesurer la différence de force entre l’état initial vitesse de vent égale à 0 et état final lorsqu’en met la soufflerie (2) en marche. The 4 wheels of the car are placed on the 4 force sensors (8) to measure the difference in force between the initial state wind speed equal to 0 and final state when put the blower (2) in market.
Pour la force de traînée est calculé à l’aide des 2 capteurs de force (5) placer sur une barre située derrière de la voiture. For the drag force is calculated using the 2 force sensors (5) place on a bar located behind the car.
[0009] Les 6 capteurs cités précédemment sont liées à un pc pour calculer et enregistrer la variation de ces coefficients en fonction de la variation de la vitesse du vent et du poids du véhicule. The 6 sensors mentioned above are related to a pc to calculate and record the variation of these coefficients as a function of the variation of the wind speed and the weight of the vehicle.

[0012] Le couple résistant appliqué est proportionnel à la masse du réservoir mobile cette dernière est réglable de la façon suivante : The applied resistive torque is proportional to the mass of the mobile reservoir, the latter is adjustable as follows:
- Lorsqu’on veut augmenter le couple l’électrovanne liée à une unité de commande s’ouvre et la quantité du liquide désirée est ajoutée dans le réservoir mobile.
Lorsqu’on veut diminuer le couple l’électrovanne reste fermée et l’unité de commande alimente la pompe qui aspire la quantité désirée qui sera refoulée dans le réservoir fixe. - When it is desired to increase the torque, the solenoid valve connected to a control unit opens and the quantity of the desired liquid is added to the mobile tank. When it is desired to reduce the torque, the solenoid valve remains closed and the control unit supplies the pump which sucks up the desired quantity which will be pumped back into the fixed tank.
