The invention provides an anisotropic chiral honeycomb structure, and relates to the technical field of morphing wings, the anisotropic chiral honeycomb structure comprises a plurality of cell elements periodically arranged in the same plane, the cell elements are of central symmetry structures, each cell element comprises a ligament, four first through hole cylinders and four second through hole cylinders, the four second through hole cylinders are arranged on the inner side of the first through hole cylinder, and the ligaments comprise a first ligament, a second ligament, a third ligament, a fourth ligament and a fifth ligament. The honeycomb structure has high out-of-plane rigidity and can bear large aerodynamic loads, and the aerodynamic shape of the wing is kept. Meanwhile, the limitation of isotropy of common four-ligament and six-ligament structures of chiral honeycombs is broken through, the property of zero Poisson's ratio in one direction and the property of negative Poisson's ratio in the other direction are achieved, the complex requirement for wing deformation can be met, and the aerodynamic performance of wings in different states can be improved.
