A NEW MEANS OF STUDYING RAILWAY AERODYNAMIC PROBLEMS. THE LONG WIND TUNNEL AT THE SAINT-CYR L'ECOLE AEROTECHNICAL INSTITUTE
UN NOUVEAU MOYEN D'ETUDE DES PROBLEMES D'AERODYNAMIQUE FERROVIAIRE: LA SOUFFLERIE A VEINE LONGUE DE L'INSTITUT AEROTECHNIQUE DE SAINT-CYR L'ECOLE
A new wind tunnel for aerodynamic tests on railway vehicles has been operational since May 1972. It meets the need felt so many times, when experimenting with high-speed trains, to have available a wind tunnel sufficiently long to take the models of trains made up of a large number of vehicles. This testing plant, built on the initiative and with the aid of S.N.C.F., comprises a 15 to 18 m long and 2.20 m wide tunnel of which the height can be regulated between 1.10 and 1.75 m. It can take 1/20 th scale models of trains 300 m long in full size. Maximum air flow speed is 60 m/s. Drag and the corresponding moments are measured by means of dynamometric bridges with strain gauges. The research carried out with this wind tunnel since it was opened has been mainly confined to the aerodynamic resistance of long trains of the TGV type and the intakes and exhausts of the turbines on ETG and RTG turbotrains.
