The invention relates to the technical field of aircrafts, in particular to a lattice sandwich wing containing nickel-titanium alloy steel wire ropes. The lattice sandwich wing containing the nickel-titanium alloy steel wire ropes comprises an upper skin and a lower skin, after the upper skin and the lower skin are fixedly connected, a containing space is formed, a lattice sandwich layer is arranged in the containing space according to a setting method, and the lattice sandwich layer is composed of a plurality of prismatic table single bodies which are tightly arranged; each prismatic table single body comprises at least three structural beams, the lower end of each structural beam is fixedly connected with the lower skin, the angles formed by the structural beams and the tangent line of the lower skin are the same, the upper end of each structural beam is fixedly connected with the upper skin, two pairs of positioning holes are symmetrically formed in the two sides of the center point of the bottom face area of each prismatic table single body, and the positioning holes are matched with the positioning holes. A nickel-titanium alloy steel wire rope penetrates through each pair of positioning holes, and the two ends of each nickel-titanium alloy steel wire rope are fixedly connected with the upper skin. The wing is small in mass, high in strength and bearing capacity and high in vibration reduction and vibration resistance.
