A testing campaign utilizing DTU’s outdoor rotating rig is described, where a novel morphing flap system developed in collaboration with the University of Bristol within the INNWIND.eu project has been evaluated and successfully demonstrated. In addition, the aerodynamic performance of ECN’s newly designed aerofoil has been evaluated in atmospheric conditions. The morphing wing is shown to achieve good performance in terms of aerodynamic lift control, and compares well with computational fluid dynamics predictions. Moreover, simple feed-forward controller implementations, also utilizing inflow sensors, show promising results in terms of dynamic load alleviation.
