Transferring aeronautics test methods to wind turbines

An electrodynamic vibration exciter pulls and pushes at the 20-metre SmartBlades DemoBlade with a force of 100 kilograms. The rotor blade oscillates with a deflection of 50 centimetres at the tip. Researchers from the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) are conducting precise analyses of these movements and the material stresses on the rotor blade. To do this, the researchers have fitted 300 acceleration and 200... ... More: Official Press Release DLR
