The invention discloses a driving device for a variable chord length wing, and belongs to the field of variant aircraft structure design, the driving device comprises a driving motor, a lead screw driving system, a connecting rod system and a nested shear plate; the driving device and the variable chord length wing rib are both mounted between the wing front beam and the wing rear beam, and the driving device is matched with the variable chord length wing rib for use; the lead screw driving system comprises a lead screw, an angle box, a positioning plate and a driving nut; the lead screw is fixed on the wing front beam through the angle box and the positioning plate; the driving motor provides power for the driving device, rotation of the lead screw is converted into translation displacement of the driving nut through the lead screw driving system, the driving nut moves on the lead screw, and the wing rear beam is driven to move front and back through the connecting rod system. The variable chord length wing can be driven, so that the area and the aspect ratio of the wing are changed, and the purposes of optimizing the lift-drag ratio, the flight speed and the maneuverability of the aircraft are achieved; and the torsion resistance of the variable chord length wing adopting a flexible structure can be compensated.

    本发明公开了一种用于可变弦长机翼的驱动装置,属于变体飞机结构设计领域,包括驱动电机、丝杠驱动系统、连杆系统以及嵌套剪切板;所述的驱动装置、可变弦长翼肋均安装在机翼前梁与机翼后梁之间,驱动装置配合可变弦长翼肋使用;所述的丝杠驱动系统包括丝杠、角盒以及定位板、驱动螺母;丝杠通过角盒和定位板固定在机翼前梁上;所述的驱动装置由驱动电机提供动力,经丝杠驱动系统将丝杠的转动转换成驱动螺母的平动位移,驱动螺母在丝杠上运动,通过连杆系统带动机翼后梁前后移动。本发明能够驱动可变弦长机翼,使机翼面积和展弦比发生改变,以此达到优化飞机升阻比、飞行速度和机动性的目的;能够补偿采用柔性结构的可变弦长机翼的抗扭能力。
