| 摘要 |
The invention is related to an actuator element (10) for an actuator (100) for the rotor blade (200) of a wind turbine (300), with at least two length variable piezoelectric elements (20) being at least partly embedded in an actuator structure (30) of composite material, whereby the at least two piezoelectric elements (20) are located in a relation to each other for accumulation of their length variation. |
