The invention discloses a multi-degree-of-freedom morphing wing based on a concave polygon mechanical superstructure. The multi-degree-of-freedom morphing wing comprises a wing rib, a skin and a wing spar, the spar comprises a spar driver and a spar negative Poisson's ratio mechanical superstructure, the spar negative Poisson's ratio mechanical superstructure is formed by arraying a plurality of unit cell structures, and the spar driver penetrates through and is connected with each unit cell structure of the spar negative Poisson's ratio mechanical superstructure; the wing rib is divided into a wing rib front connecting section and a wing rib rear connecting section; the wing rib front connecting section comprises a wing rib front driver and a wing rib front negative Poisson's ratio mechanical superstructure, the wing rib front negative Poisson's ratio mechanical superstructure is formed by arraying a plurality of unit cell structures, and the wing rib front driver penetrates through and is connected with each unit cell structure of the wing rib front negative Poisson's ratio mechanical superstructure; the wing rib rear connecting section comprises a wing rib rear driver and a wing rib rear negative Poisson's ratio mechanical superstructure, the wing rib rear negative Poisson's ratio mechanical superstructure is formed by arraying a plurality of unit cell structures, and the wing rib rear driver penetrates through and is connected with each unit cell structure of the wing rib rear negative Poisson's ratio mechanical superstructure. The morphing wing couples the bending degree, the elongation, the dihedral angle and the sweepback together, has multiple degrees of freedom, and improves the adaptability of an aircraft in different flight environments and tasks.

    本发明公开了一种基于内凹多边形机械超结构的多自由度变体机翼,包括翼肋、蒙皮和翼梁;所述翼梁包括翼梁驱动器和翼梁负泊松比机械超结构,翼梁负泊松比机械超结构由多个单胞结构阵列而成,翼梁驱动器贯穿连接翼梁负泊松比机械超结构的各个单胞结构;翼肋分为翼肋前连接段和翼肋后连接段;翼肋前连接段包括翼肋前驱动器和翼肋前负泊松比机械超结构,翼肋前负泊松比机械超结构由多个单胞结构阵列而成,翼肋前驱动器贯穿连接翼肋前负泊松比机械超结构的各个单胞结构;翼肋后连接段包括翼肋后驱动器和翼肋后负泊松比机械超结构,翼肋后负泊松比机械超结构由多个单胞结构阵列而成,翼肋后驱动器贯穿连接翼肋后负泊松比机械超结构的各个单胞结构。该变体机翼将变弯度、展长、反角和后掠耦合在一起,具有多个自由度,提高了飞行器在不同飞行环境和任务下的适应性。
