Might stick around: IWES tackles rotor blade production challenges with the Variable Glue Applicator

The longer the rotor blade, the more glue is needed to bond the blade shells together. IWES scientists have developed the Variable Glue Applicator to simplify and improve the application of adhesive.

Offshore installations: Weather and project risk analysis at IWES

Here at IWES, we assess weather risks using the Advanced Weather Time Series Scheduling (AdWaTSS) method, which is more precise than just statistics, and frequencies of tasks. For the offshore wind industry, we analyze and verify the time schedules of…

The step to the digital test procedures: hybrid testing of wind turbines

Authors: Muhammad Omer Siddiqui, Paul Robert Feja The requirements for wind turbine test benches are continuously increasing and demand, in turn, investments in test bench expansions or new test benches. Fraunhofer IWES has developed a hybrid test procedure to expand…

Nacelle Testing for Future Wind Turbines – What Lies Ahead?

Authors: Paul Robert Feja, Muhammad Omer Siddiqui Over the years, we have witnessed rapid growth in both onshore and offshore wind turbine systems. At the same time, the entire wind industry has become even more competitive, as wind turbine manufacturers…

What Happened to You, Buddy? The Evaluation of Blade Bearings

Authors: Dr.-Ing. Matthias Stammler, Karsten Behnke Whenever we have the opportunity to look at damaged bearings, we as scientists love to do so. Be it the bearings we tested in our own lab or bearings directly from the field, it…

Waves, buoys, offshore wind energy: Wind measurement in the German Bight

Author: M. Sc. Sarah Zwick Fraunhofer IWES Wind Lidar Buoys floated in the German Bight, east of the Bard Offshore 1 wind farm, at times last year. These yellow buoys ensure that comprehensive wind measurement data and meteorological parameters can…

Large-Scale Wind Farm Effects – A Key Contributor for Economic Wind Farm Operation?

Ever since the construction of the first wind farms began in the 1980s, the impact of wind turbines on the flow – the wake effect – has been a major focus not only in the field of wind energy research…

How do resonance-based testing methods increase the efficiency and lifespans of support structures?

Efficient use of materials and a long lifespan are important KPIs in the optimization of offshore wind turbines. For future, larger support structures, which are particularly expected in wind farms at greater water depths, the behavior of the foundations, in…

Wind farm optimization: Higher yield thanks to intelligent operational management

When the wind passes through the rotor disc of a wind turbine with its rotating blades, the wind speed behind the turbine is reduced – the turbine extracts kinetic energy from the wind to convert it into electrical energy. This…

Bundled wind energy expertise for virtual turbine models

Many analyses in the field of wind energy are based on virtual models. However, these simulation models are not freely available for every real wind turbine. Fraunhofer IWES solves this problem with an innovative approach. Researchers at IWES are currently…
