摘要： A rotor blade (20), especially for a rotary wing aircraft, has an aerodynamically effective rotor blade profile which comprises a profile tip section (21), a profile base (20a) with a profile core (22) and an upper and lower covering skin (30) enclosing the profile core (22), and a profile trailing edge section (23) with a trailing edge (40). A reversibly flexible flection actuator (26) is fastened with a first end to an end section of the profile base (20a) pointing towards the trailing edge (40) and projects with a second end from the profile base (20a) and the end section thereof towards the trailing edge (40). The flection actuator, with the projecting second end, forms a part of the profile trailing edge section (23) of the rotor blade profile and a mobile rotor blade flap (24) which can be deformed to an arched rotor blade flap deflection when the flection actuator (26) is bent.

摘要： The invention relates to a rotor blade (20), in particular for a rotary wing aircraft. The invention is characterised by the following: an aerodynamic rotor blade profile with a profiled leading edge region (21), a profile base body (20a) comprising a profile core and a lower and upper skin (30) that encases the profile core (22) and a profiled trailing edge region (23) with a trailing edge (40); a reversibly flexible support element (26), the first end of which can be fixed to an end region of the profile base body (20a) that is oriented towards the trailing edge (40) and the second end of which projects freely out of the profile base body (20a) and the end region thereof towards the trailing edge (40), forming a movable rotor-blade flap (24); and several actuators (35) that are operatively connected to the projecting second end of the reversibly flexible support element (26), whereby a modification in the length of the actuators causes an arc-shaped deflection of the flap. The second end of the reversibly flexible support element (26) forming the rotor-blade flap (24) is divided into several segments, when viewed in the direction of the span (S), by means of cut-out sections (34) and at least one actuator (35) is assigned to each segment.
