The rotor blades equipped with these technologies are intended to have the ability to adapt optimally to variable wind conditions, withstand gust loads better, and be capable of achieving higher energy yields. At the same time, the blades must remain light enough to be cost-effective to manufacture, transport, and install. The SmartBlades1 project demonstrated the potential of three different technologies. On one hand, blades were designed to passively adapt to the load situation through a bend-twist coupling (BTC). Additionally, the application of leading and trailing edge flaps to control and influence the aerodynamic behavior of the blade system was studied. These systems function similarly to aircraft high-lift systems and control surfaces.
