The invention discloses a shape memory alloy driven corrugated core flexible wing trailing edge structure. The structure comprises a spar, a composite material corrugated plate, a deformation plate, an upper airfoil skin, a lower airfoil skin and a rigid empennage, the spar and the rigid empennage are fixedly connected through an upper airfoil skin and a lower airfoil skin, the upper airfoil skin and the lower airfoil skin form an included angle and are arranged at intervals up and down, the upper airfoil skin and the lower airfoil skin are fixedly connected through a composite corrugated plate, and the end, close to the spar, of the composite corrugated plate is fixedly connected with the middle of the spar. A plurality of deformation plates are fixedly mounted in the composite material corrugated plate; deformation driving of the deformation plate enables the trailing edge of the wing to deform. The flexible trailing edge is simple in structure and convenient to control, the deformation states of the deformation plates are independently controlled through a circuit, and control over multiple bending degrees of the whole flexible trailing edge is achieved by controlling the deformation states of the multiple sets of deformation plates so that the flexible trailing edge can adapt to multiple different flight working conditions.
