Fraunhofer IWES Celebrates 10th Birthday

Fraunhofer IWES was founded in 2009 and has since developed into an internationally renowned research institute for the wind energy industry. The IWES celebrated its birthday in Bremerhaven with high-ranking guests from Germany and abroad.



Worldwide First Validation of Aerodynamics of Large Wind Turbines

Fraunhofer IWES is measuring the aerodynamics of wind turbines with a rated power of more than five megawatts. This way it shall be assessed whether the model calculations used to date are also valid for large wind turbines, which will primarily be built offshore in the future.



New European Wind Atlas published

Researchers developed and validated new methods for assessing the relevant wind resources. One central aim of the wind atlas project was the development of standardized online maps for site assessment. Information about the long-term wind climate at each grid point in the EU can be accessed via a web interface.



Bearing Test Bench Now Fully Functional

Over the past months, the first blade bearings have been tested in Hamburg on the new BEAT 6.1 test bench using a highly simplified yet customary setup.

The installation of specially manufactured hybrid components means that, with immediate effect, dynamic loads can also be applied to the bearing, which, in turn, produces particularly realistic test conditions. 


What truly defines the “IWES spirit”

Describing the culture of an institute in words is no mean feat. It is often a matter of shared experiences, the development of extraordinary approaches, and a common understanding of the expected level of quality. 

Our work generates a practical added value and turns innovative ideas into reality. Find out more – from our employees themselves.



How accurately can system test benches simulate field tests?

Two system test bench campaigns are part of the research project „CertBench“. They are carried out with the nacelle of a 3 MW wind turbine which is already certified. Therefore, the test bench results can be compared directly to electrical porperties determined during field measurements. The target of the project is to accelerate the certification process.
