Aerodynamics experiment in the cryogenic tunnel in Cologne
Aerodynamics experiment in the cryogenic tunnel in Cologne
In the cryogenic wind tunnel operated by Deutsch Niederländische Windkanäle (DNW, 'German-Dutch Wind Tunnels') in Cologne-Porz, the aerodynamic properties of trains are being analysed. This involves the use of accurately detailed models, which can only be manufactured using computer-controlled precision machines.
