The invention discloses a high aspect ratio thin wing type wing body butt joint structure which comprises a fuselage assembly, a wing assembly, a wing body butt joint tension bolt and a wing body butt joint anti-shear pin. The wing assembly comprises a skin assembly, a framework assembly, a copper sleeve required by a wing body butt joint bolt and a self-made flexible self-adaptive nut assembly. The feasibility of the assembly process of all assemblies and the wing body butt joint convenience are considered, and when the requirement that the high-speed unmanned aerial vehicle with the high aspect ratio and the thin wings generates large bending moment and shearing force is met, loads are effectively transmitted, and the large joint structure weight coefficient is avoided. The device is clear in principle, feasible in design scheme, reasonable in separation surface and good in manufacturability, the structural strength and rigidity meet the model use requirements, and good interchangeability is achieved.

    本发明公开了一种大展弦比薄翼型翼身对接结构,包括机身组件、机翼组件、翼身对接拉紧螺栓、翼身对接抗剪销,机身组件包含了蒙皮组件和骨架组件,机翼组件包含了蒙皮组件、骨架组件及翼身对接螺栓所需要的铜套和自制柔性自适应螺母组件。综合各组件装配工艺可行性、翼身对接便捷性角度考虑,在满足大展弦比薄机翼的高速无人机产生较大弯矩和剪力时,为了有效传递载荷及避免较大的接头结构重量系数。本发明原理清晰,设计方案可行,分离面合理,工艺性好,结构强度、刚度满足型号使用要求,具备良好的互换性。
