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 partition plate which is arranged as a partition interface between the central oil tank and the wing main oil tank. By means of the design method, fuel oil loss caused by the fact that the non-inclusive rotor of the engine bursts and breaks down the oil tank is reduced, and the structure setting efficiency is guaranteed.
本发明属于飞机机翼油箱结构技术领域,公开一种机翼油箱结构的设计方法及机翼,该设计方法先获取发动机的转子的爆破碎片的扫掠路径,以及获取机翼的主承力结构的布置位置;再确定内侧界面肋板、中间界面肋板以及外侧界面肋板相对发动机的转子的爆破碎片的扫掠路径的位置关系,内侧界面肋板、中间界面肋板以及外侧界面肋板均为机翼的主承力结构中的翼肋,以及确定油箱隔板的位置和数量;之后再使内侧界面肋板、油箱隔板、中间界面肋板以及外侧界面肋板连接形成阶梯状的界面分隔板设置为中央油箱与机翼主油箱之间的分隔界面。本发明通过该设计方法减少发动机非包容性转子爆破击穿油箱造成的燃油损失,并保证结构设置效率。
