A top speed of 300 km/h: even the Audi R8’s top speed can be simulated here. With its low noise rotor measuring some five metres in diameter, the fan in the aeroacoustic wind tunnel has an output of 2.6 megawatts. The accelerated air travels along a tubular section with four corners which prevent turbulence and background noise. Before entering the test section, the air flow passes through three screens and a nozzle. Now, largely free of turbulence, constant and directionally uniform, the air flow accelerates up to 300 km/h. It now enters the test section.
