    摘要: The invention relates to a rotor blade (20), especially for a rotary wing aircraft. The invention is characterized in that an aerodynamically effective rotor blade profile with a profile nose region (21), a profile base body (20a) with a profile core, an upper and lower cover skin (30) that envelops the profile core (22), and a profile rear edge region (23) with a rear edge (40) and a reversibly bendable supporting member (26) that can be attached with the first end to the end region of the profile base body (20a) pointing toward the rear edge (40) and projects with the second end freely out of the profile base body (20a) and its end region toward the rear edge (40) and forms a movable rotor blade flap (24), and several actuators (35) that are dynamically connected to the projecting second end of the reversibly bendable supporting member (26) and an arc-shaped flap deflection can be initiated via the change in length of the actuators, the second end of the reversibly bendable supporting member (26) that forms the rotor blade flap (24) viewed in the direction of the span (S) being divided by notches (34) into several segments to which at least one actuator (35) at a time is assigned.

    摘要: A rotor blade including a rotor blade profile including a profile tip region, a profile trailing edge region including a trailing edge and a profile body having a profile core. A covering skin including an upper skin and a lower skin encase the profile core. A reversibly bendable flexural actuator including a first actuator end disposed at the trailing edge region of the rotor blade profile and a second actuator end projecting past the profile body toward the trailing edge. The second actuator end forms part of the 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 a bending of the flexural actuator.

    摘要: An aerodynamic profile includes a main profile body defining a profile depth direction and being shear-flexible in the profile depth direction, a tension-stiff and compression-stiff upper covering skin, a tension-stiff and compression-stiff lower covering skin, wherein the upper and lower covering skins envelope the main profile body, a bearingless and hingeless rear profile deformation region disposed at a rear edge region, and at least one actuator disposed in the main profile body. The at least one actuator is configured to initiate a flexural motion of the main profile body resulting in a curvature of the upper and lower covering skins and to deform the rear profile deformation region and so as to yield a flap deflection directed opposite to a direction of the flexural motion.
