The invention discloses a wing with a variable sweep angle and shape. The wing comprises at least two wing bodies arranged in sequence, a driving mechanism arranged between every two adjacent wing bodies and used for changing the angle of the wing bodies in the front-back direction, and a flexible skin connected between every two adjacent wing bodies. Every two adjacent wing bodies are connected through a hinge structure. The driving mechanism comprises a steering engine, a rocker arm and a connecting rod; and the steering engine is arranged on one wing body, a main shaft of the steering engine is connected with the rocker arm, one end of the connecting rod is hinged to the rocker arm, and the other end of the connecting rod is hinged to the other wing body. The wing is simple in structureand low in cost, and is a self-adaptive wing which is based on imitation of bird wings, has a capability of changing the shape of a wing surface, is large in deformation amplitude and can meet different flight environments.

    本发明公开一种掠角和外形可变的机翼,其特征在于,包括至少两个依次排列的机翼本体、设置在相邻两个机翼本体之间用于改变机翼本体前后方向角度的驱动机构以及连接在相邻两个机翼本体之间的柔性蒙皮;其中,相邻的两个机翼本体之间通过铰接结构连接;所述驱动机构包括舵机、摇臂以及连杆;所述舵机设置在其中一个机翼本体上,该舵机的主轴与所述摇臂连接,所述连杆的一端与所述摇臂铰接,另一端与另一个机翼本体铰接。该机翼结构简单,成本低廉,是一种以模仿鸟类翅膀为基础,具有改变翼面形状能力,变形幅度大,能够满足不同的飞行环境的自适应机翼。
