Abstract:
1. A rotor blade comprising: a rotor blade profile having a profile tip region, a profile trailing edge region including a trailing edge and a profile body having a profile core and a covering skin including an upper skin and a lower skin, the covering skin encasing the profile core; and a reversibly bendable flexural actuator including a first actuator end to be fastened at an end region of the profile body, the end region pointing towards the trailing edge, and a second actuator end projecting past the profile body toward the trailing edge; wherein the projecting second actuator end forms part of the profile trailing edge region and forms a movable rotor blade flap, the movable rotor blade flap being deformable into an arc-shaped rotor blade flap deflection upon bending of the reversibly bendable flexural actuator, wherein the reversibly bendable flexural actuator includes a planar shape and at least one of a plate shape and a ribbon shape, wherein the reversibly bendable flexural actuator is disposed on at least one support layer wherein the at least one support layer is plate-shaped and reversibly bendable.
