    • 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.
    • 本发明涉及一种转子叶片(20),特别是用于旋转翼飞机。 本发明的特征在于,与具有轮廓芯和简档芯包覆的轮廓鼻区域(21),简档基体(20a)的空气动力学有效的转子叶片轮廓(22)上和下覆盖皮(30),和一个配置文件 -Hinterkantenbereich(23)具有第一端与到指向轮廓基体(20A)的端部区域的后缘(40)的拖尾边缘(40)和一个可逆地弯曲支撑构件(26)能够被紧固,并用的​​第二端释放 轮廓基体(20a)和其端部区域到所述后缘(40)伸出和可动转子叶片翼片(24)和多个致动器(35)是与所述可逆可弯曲支承部件的突出的第二端可操作地连接(26) 和圆弧状的襟翼偏转可以在长度变化来启动,其特征在于,所述转子叶片翼片(24)形成所述可逆弯曲Tr的第二端 被认为是gerelements(26)在翼展方向(S)由切口(34)划分成多个分段,其中的每一个的至少一个致动器(35)被分配。
