摘要： A wind turbine blade comprises a main blade body and trailing edge section movably connected to the main blade body, and an actuator structure internally within the blade. The actuator interconnects the trailing edge section and the main blade body, and it comprises a stack of a plurality of piezoelectric elements, so that the stack of piezoelectric elements is capable of operating as a linear actuator. The actuator structure is arranged such that it is capable of causing the trailing edge section to move or deform relative to the main blade body in response to aerodynamic loads on the blade. The actuator structure is controllable by a control system applying a voltage to the stack of piezoelectric elements in response to, e.g., detected wind or load characteristics.
