I'll Catch You If You Fall
Large wind tunnel, Berlin-Adlershof
"The large wind tunnel was built between 1932 and 1934. It was used for aerodynamic experiments in air streams at speeds of over 200 km/h. The air stream was generated by a rotor with eight impellers, 8.5 metres across, connected to an electric motor with an output of 2,000 kW. The tubular plant has external dimensions of 58 m x 26 m and a diameter of 8.5 m - 12 m. It was used to direct an air stream on to aircraft parts (wings, coatings, tail, etc.) in a measuring chamber, where the resistance was measured. This enabled aircraft shape and surfaces to be optimised. A particular feature of this wind tunnel - still remarkable today - is its concrete construction using the Zeiss-Dywidag method with a wall thickness of just 8 cm." www.hu-berlin.de/en/about/campus/adlershof/overview/techn...
