Design method of wing fuel tank structure and wing

The invention belongs to the technical field of aircraft wing fuel tank structures, and discloses a design method of a wing fuel tank structure and a wing, the design method comprises the following steps: firstly obtaining a sweeping path of blasting fragments of a rotor of an engine, and obtaining an arrangement position of a main load-bearing structure of the wing; the position relation of sweeping paths of blasting fragments of an inner side interface rib plate, a middle interface rib plate and an outer side interface rib plate relative to a rotor of the engine is determined, the inner side interface rib plate, the middle interface rib plate and the outer side interface rib plate are wing ribs in a main force bearing structure of a wing, and the positions and the number of fuel tank partition plates are determined; and then the inner side interface rib plate, the oil tank partition plate, the middle interface rib plate and the outer side interface rib plate are connected to form a stepped interface partiti
