The FKFS aerodynamics and aeroacoustics wind tunnel is among the most capable facilities of its kind in Europe. It is specifically designed for aerodynamic and aeroacoustic investigations of passenger cars, vans, and motorsport vehicles, while flow speeds of up to 260 km/h also allow its use for a wide range of additional applications.

The wind tunnel offers extensive experimental capabilities in both aerodynamics and aeroacoustics. Aerodynamic investigations include, among others, the measurement of forces and moments, the acquisition of surface pressures and flow fields, as well as various flow visualization techniques. Aeroacoustic investigations are based on a broad range of measurement methods, including the use of artificial heads, various types of microphones (e.g. near-field, free-field, and pressure microphones), microphone arrays for sound source localization, as well as complementary vibration and structure-borne noise measurements.

The wind tunnel features a horizontal flow layout with an open-jet test section (Göttingen-type design). A 5-belt system consisting of a central belt and four wheel drive units, in combination with effective boundary-layer conditioning, enables the reproducible simulation of road-representative inflow conditions. Alternatively, a 3-belt system is available in which the entire floor beneath the vehicle is moving, providing optimal conditions particularly for the development of motorsport vehicles. In addition, the FKFS swing system allows the turbulence encountered during real on-road driving to be transferred into the wind tunnel.
