The invention discloses a multi-dimensional deformation wing based on a regular tetrahedron-octahedron mechanism, and relates to the technical field of aircrafts. The problems that the variant of an existing aircraft is mainly achieved by changing the shape of a local wing, the variant is basically embodied as single or two-dimensional deformation in a plane, the deformation capacity is relatively weak, and the requirement for continuously changing the aerodynamic shape of the wing in the wide speed domain crossing process from subsonic speed to hypersonic speed or from high altitude to space cannot be met are solved. The device can realize four deformation forms of stretching, sweepback changing, bending and torsional deformation, the spanwise stretching rate of the structure can reach 30%, the sweepback angle is 36 degrees, the spanwise bending angle in an extension state is +/-30 degrees, and the torsional angle can reach +/-10 degrees; the multi-dimensional deformation wing of the mechanism has more deformation modes, so that the deformation capability is improved, and the requirement of continuously changing the aerodynamic shape of the wing in the cross-wide speed domain process from subsonic speed to hypersonic speed or from high altitude to space is further met. The invention is applicable to the field of deformable wings.

    一种基于正四面体‑八面体机构的多维度变形机翼,涉及飞行器技术领域。为解决现有飞行器的变体主要通过改变局部机翼形状而实现,基本上体现为单一或平面内两个维度的变形,变形能力相对较弱,还无法满足从亚音速到高超声速或高空到太空的跨宽速域过程中连续改变机翼气动外形要求的问题。该装置可以实现伸缩、变后掠、弯曲以及扭转变形四种变形形式,该结构展向伸缩率可达到30%,后扫掠角度为36°,伸长状态下展向弯曲角度为±30°,扭转角可达±10°;此种机构的多维度变形机翼的变形方式较多,提高了变形的能力,进而满足从亚音速到高超声速或高空到太空的跨宽速域过程中连续改变机翼气动外形要求。本发明适用于可变形机翼领域。
