Rotor Blade with Bend-Twist Coupling Passes Extreme Load Test

Wind Industry Profile of

Compared with other rotor blade prototypes measuring more than 80 m in length from industrial customers, this test object is small, nevertheless it is certainly keeping IWES´ scientists on their toes: for the very first time, a rotor blade with bend-twist coupling was tested whose design was developed by Fraunhofer IWES in a previous project.

When subject to aerodynamic loads, the prebend of the blade results in mechanical deformation during operation, the purpose of which is to mitigate the loads on the overall structure. Following further tests, three identical models will be constructed by the German Aerospace Center (DLR) and shipped to the USA. The blades will then be installed there on a research turbine for a measurement campaign lasting several months. These activities... ... More: Official Press Release IWES
