The Audi Aeroacoustic Wind Tunnel: Final Design and First Operational Experience

摘要

Audi's new full scale aeroacoustic wind tunnel is under full operation now. The new facility is designed for full scale automotive testing of aerodynamics and aeroa- coustics for vehicles up to 3 m~2 frontal area at wind speeds up to 300 kph. The highlights are the unique ground simulation system with boundary layer suction and a 5-belt-system, and the extremely low background noise of only 60 dB(A) at 160 kph.
