Test Facility Description

The wind tunnel is among the biggest university-owned tunnels in the world.

Among other things, it is possible to expose a part of a wind turbine blade to wind speeds up to 105 meters a second or 378 kilometres pr. hour, corresponding to three times hurricane strength.

The wind will be created by a gigantic fan with a diameter of 4,7 meters. Furthermore, the test section will be enclosed in a soundproof room to avoid reflections and absorb noise.
