为提升某民用固定翼舰载无人机的气动性能,本文提出一种基于多段式驱动结构的变后缘弯度机翼设计方案,采用黏性流体k –ω湍流模型,对传统单段翼型与2 ~ 5 段式变形机翼开展跨迎角气动特性对比分析,通过升力系数、升阻比等关键参数的量化评估,确定3 段式变形机翼为最优气动方案。基于该方案开展机翼结构优化与仿真验证,结果表明,针对3 段式结构建立的运动学模型经仿真验证,可实现30° 目标变形角度的精准控制,各旋转肋协同运动良好,机翼外形连续光滑无卡滞。有限元强度分析显示,结构最大 Von-Mises 应力为287.12 MPa,安全裕度3.81(基于15 – 5PH 不锈钢屈服强度1093 MPa),满足设计载荷下的强度要求。
To improve the aerodynamic performance of civil fixed-wing carrier-based UAV
this study presents a variable trailing-edge camber wing design scheme based on a multi-segment drive mechanism. Using the k – ω turbulence model for viscous fluids
comparative aerodynamic analyses across angles of attack are conducted for traditional singlesegment wing structures and 2–5-segment deformable wing structures. Through quantitative evaluation of key parameters such as lift coefficient and lift-to-drag ratio
the 3-segment deformable wing is identified as the optimal aerodynamic configuration. Structural optimization and simulation verification of the wing are carried out based on this scheme. The results show that the kinematic model established for the 3-segment structure achieves precise control of the target deformation angle of 30° through simulation verification
with excellent collaborative motion of each rotating rib and a continuously smooth wing profile without jamming. Finite element strength analysis indicates that the maximum Von-Mises stress in the structure is 287.12 MPa
with a safety margin of 3.81 (based on the yield strength of 1093 MPa for 15–5PH stainless steel)
meeting the strength requirements under designed loads. The proposed multi-segment variable trailingedge camber wing design method provides a complete parameter matching and performance verification system for the engineering implementation of high-lift wings in carrier-based UAVs.
