Wind Tunnel Centre
Our position as a recognised expert in all matters relating to wind energy is reinforced with our own research and measuring equipment. Four calibration wind tunnels and two special tunnels (ice and pressure) form the Wind Tunnel Centre at our headquarters in Varel. The calibrations are recognised by the independent institutions Deutsche Akkreditierungsstelle GmbH (DAkkS) and MEASNET. Since 2009, one of the calibration wind tunnels has been serving the German national metrology institute (Physikalisch-Technische Bundesanstalt – PTB) as a comparison and reference channel. A PTB transfer standard is installed here to represent the physical unit "meters per second" for air flows.
Large wind tunnel in Bremerhaven
In addition, our acoustically-optimised large wind tunnel in Bremerhaven has been operational since 2008. The tunnel offers high wind speeds at low levels of turbulence, together with the most advanced drive and control techniques for ideal conditions for research and development. The aerodynamic and acoustic optimisation of rotor blades benefits from the data obtained in our wind tunnel, as do the marine and automotive industries.
