Ford’s aero-acoustic wind tunnel

Reinhard Grundmann; Carl Kramer; Wigberth Kohl; Bernd Konrath

Ford’s wind tunnel in Cologne has been in operation since 1983. It was designed as an aerodynamic wind tunnel. Flowinduced noise measurements were impossible because of the extremely high self-noise level caused by the fan. In 1998, the wind tunnel was converted into an aero-acoustic wind tunnel, with development and engineering work being provided by WSP Consulting Engineers, Aachen.

Der Aeroakustik-Fahrzeugwindkanal von Ford

Reinhard Grundmann; Carl Kramer; Bernd Konrath; Wigberth Kohl

Der 1983 in Betrieb genommene Fahrzeug-Windkanal der Ford-Werke AG, Koln, war ursprunglich nur fur aerodynamische Messungen konzipiert. Akustische Messungen von Stromungsgerauschen waren aufgrund des sehr hohen Eigengerauschpegels nicht moglich. 1998 wurde dieser Windkanal nach Planung der Ingenieurgemeinschaft WSP, Aachen, in einen Aeroakustik-Windkanal umgebaut, so dass nunmehr Stromungsgerauschmessungen sowohl auserhalb als auch innerhalb des Fahrzeugs durchgefuhrt werden konnen.
