The wind tunnel

The Department of Steel Construction has a Göttingen-type wind tunnel with a closed circuit and an open measuring section. In the area of the measuring section, the low-speed wind tunnel is equipped with a six-component wind tunnel balance for static tests and additionally with a frame for the elastic suspension of partial models for dynamic tests.
 

The equipment of the wind tunnel and the open measuring section, with the associated good accessibility of the test objects, offers a wide range of applications such as the measurement of aeroelastic instabilities on section models in the wind tunnel.
