  • Area: approx. 2200 m2 - it corresponds to approx. 5 city buses long and 2 city buses wide.
  • Budget: 85.7 million DKK
  • Building owner: DTU

The new National Wind Tunnel will be inaugurated on April 10 2018. The wind tunnel is expected to be put into service in September 2018.

After several years of work, the National Wind Tunnel at DTU Risø Campus will finally be opened. The inauguration will take place on April 10, where business partners and industry are invited.

The Poul la Cour Tunnel, as it is called in colloquial language, becomes part of the national research infrastructure and will serve both research institutions and industry globally.
The wind tunnel is one of the largest university-owned tunnels in the world, and the combination of test opportunities makes the wind tunnel the only one of its kind, not only nationally, but also globally. This is due to the wind tunnel size, high flow rates and the ability to combine aerodynamic and noise measurements. One can, for example expose a part of a wind turbine wing for wind speeds up to 105 meters per second or 378 km/h. It corresponds to more than three times hurricane strength.

Peter Hauge Madsen, Director of DTU Wind Energy, says about the wind tunnel:

“We have been waiting for the wind tunnel for a long time. We know that the industry also has, so April 10 will be a joyous day. The wind tunnel helps to strengthen Denmark's position in the wind energy area.”

In use for September 
Although the wind tunnel will be officially inaugurated on April 10, the first months will be used to test and calibrate the wind tunnel.  We are looking forward to use it for research and industrial tasks in the autumn, Peter Hauge Madsen says.

The wind tunnel is expected to be put into service in September 2018.
