The invention discloses a rigid-flexible coupling variable-camber wing leading edge mechanism, and relates to the technical field of wings, the rigid-flexible coupling variable-camber wing leading edge mechanism comprises a leading edge supporting plate, a leading edge flexible skin, a leading edge deformation assembly, a driving assembly and a variable-camber leading edge mechanism, has only one degree of freedom, is singly controlled by rotation of a driving shaft, and can control a leading edge to be kept at an expected angle within a deflection range; the structure is simple, the lightweight and driving reliability of the wing are facilitated, the Watt six-bar mechanism can meet the motion trail requirements of different longitudinal beams in the leading edge airfoil in the driving deformation process, the flexible skin of the leading edge of the wing can be accurately deformed, the driving assembly adopts a turbine worm form, the self-locking function after deformation is completed can be achieved, and the safety of the wing is improved. The front edge deformation assembly adopts a symmetrical design, and the symmetrical surfaces of the driving rods, the supporting seats and the longitudinal beams are unified, so that the out-of-plane bending moment is effectively reduced, an additional load transmission structure is not needed, and sufficient design space is reserved for other structures in the wing.

    本发明公开一种刚柔耦合变弯度机翼前缘机构,涉及机翼技术领域,包括前缘支撑板、前缘柔性蒙皮、前缘变形组件与驱动组件,变弯度前缘机构,只有一个自由度,由驱动轴旋转单一控制,可以控制前缘在偏转范围内保持在期望角度,且结构简单,有利于机翼轻量化和驱动可靠性,瓦特六杆机构可以满足前缘翼型内不同纵梁驱动变形过程中的运动轨迹要求,可使机翼前缘柔性蒙皮产生准确的变形,驱动组件采用涡轮蜗杆形式,可以实现变形完毕后的自锁功能,提高了机翼变形状态的承载能力,前缘变形组件采用对称设计,各驱动杆、支撑座和纵梁对称面统一,有效减小了面外弯矩,不需要额外传递载荷的结构,给机翼内部其他结构保留了充足的设计空间。
