The invention discloses a morphing wing with variable chord length, camber and elongation and an aircraft, and belongs to the technical field of morphing wing structure design. A wing rib of the wing comprises chord-length-variable single crystal cell structures and camber-variable single crystal cell structures, the chord-length-variable single crystal cell structures are sequentially connected to form a wing rib body, and the front end and the rear end of the wing rib body are connected with the camber-variable single crystal cell structures respectively; the variable chord length single crystal cell structure comprises a first connecting frame composed of X-shaped connecting rods and V-shaped connecting rods, the two X-shaped connecting rods are connected together side by side, the middles of the two X-shaped connecting rods jointly form a quadrilateral frame, the V-shaped connecting rods are located in the quadrilateral frame, and the two ends of each V-shaped connecting rod are connected with the middle of the corresponding X-shaped connecting rod, so that the middle of the first connecting frame forms a special-shaped structure. The variable-camber single crystal cell structure comprises a second connecting frame consisting of a horizontal connecting rod, a wavy connecting rod and a reinforcing connecting rod; the two wave-shaped connecting rods are symmetrically distributed on the upper side and the lower side of the horizontal connecting rod, each bent part of each wave-shaped connecting rod is connected with the horizontal connecting rod through a reinforcing connecting rod, and the reinforcing connecting rods incline towards the free end of the variable-camber single crystal cell structure. The wing has good rigidity, deformation accuracy and aerodynamic performance.
