The invention provides a torsion wing with a tension-torsion coupling characteristic based on cell element stacking, and relates to the technical field of wings, the torsion wing comprises a wing root, a linear motor, a cantilever structure, a driving straight rod, a wing rib and a wing tail end; the two ends of the cantilever structure are fixedly connected with the wing root and the wing tail end correspondingly, the linear motor is fixedly connected with the wing root, one end of the driving straight rod is in transmission connection with the driving end of the linear motor, the other end of the driving straight rod is rotationally connected with the wing tail end, and the cantilever structure is formed by stacking a plurality of cell elements with the tension-shear coupling deformation characteristic. The linear motor can drive the cantilever structure to twist when driving the straight rod to move in the length direction of the straight rod. The invention has a continuous configuration variable function, gives consideration to the bearing capacity of the wing, can remarkably improve the section torsion capacity under the action of tension, and can continuously regulate and control the torsion angle, change the effective attack angle of each section of the wing in the spanwise direction and adjust the aerodynamic load distributed in the spanwise direction of the wing surface, thereby improving the aerodynamic efficiency of the wing.
