The research program MX100 - Consideration of aero-acoustics and passive safety in the design of TGV

During the world speed record campaign in 1990, SNCF has proved that beyond 320 km/h, aerodynamic noise is much more important than rolling noise for actual shapes of TGV. Therefore, decreasing the aero-acoustic signature of high speed trainsets becomes an important challenge for the coming years if we want to...
