Selected results on the development and testing of smart blades technologies for wind turbines

Within the frame of the Smart Blades and the SmartBlades2 projects, different technologies for developing smart rotor blades for wind turbines have been developed and are still being studied and tested. These cover the three following technologies: bend-twist coupled rotor blades; rotor blades with trailing edge flaps and rotor blades with leading edge slats. In addition, cross-technology topics that need to be considered for successfully implementing all three technologies as well as for evaluating their performance within a wind turbine system are being studied.
