学生需完成一架小型固定翼无人机的机翼结构设计。给定无人机的基本参数、翼型、翼展、弦长分布以及设计载荷工况。确定机翼结构布局形式，选择结构材料，设计翼梁、翼肋、蒙皮的布置与初步尺寸。使用材料力学和薄壁结构理论进行强度校核，包括弯曲正应力、剪应力、局部稳定性校核。在满足强度和刚度要求的前提下，尽可能减轻结构重量。提交完整的设计报告，包含结构简图、设计计算过程与重量估算。
Students complete wing structural design for a small fixed-wing UAV. Given basic UAV parameters, airfoil, wingspan, chord distribution, and design load cases, determine wing structural layout, select materials, and design preliminary dimensions of spars, ribs, and skin. Perform strength verification using mechanics of materials and thin-walled structure theory, including bending normal stress, shear stress, and local stability checks. Minimize structural weight while satisfying strength and stiffness requirements. Submit complete design report with structural schematics, calculation process, and weight estimation.
