Two aeroacoustic wind tunnels have been inaugurated by Renault (www.renault.com), Peugeot Citroen (www.peugeot.com), and the French Institute of Engineering Studies in Saint-Cyr l'Ecole in France, to investigate on the reduction of the aerodynamic drag of vehicles, aerodynamic noise for the comfort of passengers, dynamic stability of the vehicle, as well as the effects of side winds. The main tunnel will measure 258 ft2 with a ¾ open jet design that is large enough to accommodate minivans. Wind velocity in the main tunnel can reach as high as 149 mph.
