Title: ACTUATOR DEVICE FOR A WIND TURBINE, WIND TURBINE AND METHOD OF ASSEMBLY
Abstract:
The invention relates to an actuator device (10) for a wind turbine (100), in particular for a wind turbine rotor blade (108), and also an associated wind turbine (100) and a method of assembly, with an actuator component (20) and a control component (80), wherein the actuator component (20) has at least one actuator layer (30) with a preferential direction (32) and, substantially parallel to the actuator layer (30), at least one exciting layer (40), wherein the actuator layer (30) comprises a photoactuator (34), wherein the photoactuator (34) is designed to change a strain and/or stress of the actuator layer (30) in the preferential direction (32) on the basis of excitation light, wherein the exciting layer (40) is designed to guide excitation light into the actuator layer (30), wherein the control component (80) comprises a light source (84) and a light guide (82), wherein the light source (84) is arranged away from the exciting layer (40) and is connected to the exciting layer (40) by means of the light guide (82). The actuator device (10) makes it possible to ensure greater operational reliability.
