The invention discloses a morphing wing based on a metamorphic mechanism and an aircraft. The morphing wing comprises a plurality of wing ribs, a metamorphic module and a driving mechanism, and the wing ribs are sequentially connected through the metamorphic module in the transverse direction to form a wing body; the metamorphic module comprises two sets of multi-connecting-rod metamorphic mechanisms, each multi-connecting-rod metamorphic mechanism comprises a first connecting rod and four second connecting rods, and every two of the four second connecting rods form one set and are located on the two opposite sides of the first connecting rod correspondingly. One ends of the second connecting rods are hinged to the first connecting rods, and the other ends of the second connecting rods are hinged to wing spars of the wing ribs, so that the first connecting rods, the two wing spars and the four second connecting rods form a double-parallelogram structure sharing the first connecting rods; the driving mechanism is configured to act on the two sets of multi-connecting-rod metamorphic mechanisms so as to drive the wing body to be switched among the variable extension configuration, the singular configuration and the variable sweepback configuration. According to the invention, wingspan change and sweepback change can be realized, and the structure is compact and the stability is good.
本发明公开了一种基于变胞机构的变体机翼以及飞行器。其中,变体机翼包括多个翼肋、变胞模块和驱动机构,多个翼肋沿横向依次通过变胞模块相连接以形成机翼主体;变胞模块包括两组多连杆变胞机构,多连杆变胞机构包括第一连杆以及四个第二连杆,四个第二连杆两两一组并分别位于第一连杆的相对两侧;第二连杆的一端与第一连杆相铰接、第二连杆的另一端与翼肋的翼梁相铰接,以使得第一连杆、两个翼梁和四个第二连杆形成共用第一连杆的双平行四边形结构;驱动机构被配置为分别作用于两组多连杆变胞机构以驱使机翼主体在可变展长构型、奇异构型和可变后掠构型之间切换。本发明可实现翼展变化和后掠角变化两种变形,具有结构紧凑和稳定性好的优点。
