The invention discloses a drive for enabling a wing to generate torsional deformation, and belongs to the field of morphing aircraft structure design. The drive device is composed of a motor, a drive shaft, a supporting plate, a worm, a cutting worm gear, a composite round pipe, a first connecting plate and a second connecting plate; and the first connecting plate and the second connecting plate are respectively positioned on webs of a fixed-section wing rib and a deformed-section wing rib of the wing. The driving shaft is connected to the fixed section wing rib through the connecting plate, the motor drives the worm and gear to drive the driving shaft to rotate, and the driving shaft transmits torque to the deformation section wing rib through the composite round pipe and drives the deformation section wing rib to rotate, so that the wing deformation section is subjected to torsional deformation. The direction and size of the torsion angle of the wing can be actively adjusted, and the scheme is high in feasibility and practicability. According to the invention, the worm gear and the worm are used for transmitting torque, so that controllable torsion angles are generated among different wing sections along the spanwise direction, and the torsion of the wing structure is realized.

    本发明公开了一种使机翼产生扭转变形的驱动,属于变体飞机结构设计领域,所述的驱动装置由电机、驱动轴、支撑板、蜗杆、裁截蜗轮、复材圆管、第一连接板、第二连接板;所述的第一连接板、第二连接板别位于机翼的固定段翼肋和变形段翼肋的腹板上。驱动轴通过连接板连接在固定段翼肋,电机驱动蜗轮蜗杆带动驱动轴转动,驱动轴借助复材圆管把扭矩传递给变形段翼肋,驱使变形段翼肋转动,使机翼变形段发生扭转变形。本发明可以主动调节机翼扭转角方向和大小,且方案可行性和实用性高。本发明利用蜗轮蜗杆传递力矩,使沿展向的不同翼型截面之间产生可控的扭转角,实现机翼结构的扭转。
