The Fraunhofer Research Institution for Large Structures in Production Engineering and the company Nordex have developed a method for combined fatigue behavior and climatic change testing of full-scale rotor blade components. The related test bench allows the testing of bonded or integrated components under realistic conditions.

Cyclic Load

The wind energy economy has a share of 30 % of the net electric consumption in Germany. Hence, it has long been considered one of the main instruments for the German energy transition. Due to high price pressure, the trend is towards bigger, intelligent and more efficient wind turbines. A main part of the plant is the rotor blade. With sensors and actuators, integrated in the blades, the wind turbines are able to adapt to changing environmental conditions. And with the aid of system monitoring, downtimes are minimized. Furthermore, aerodynamic components, such as vortex generators and serrations, which are applied to the rotor blade surface, help to...
