基于柔性翼肋的变形机翼几何参数设计
A Compliant Rib Based Morphing Wing Geometric Parameters Design
【摘要】 为了实现柔性翼肋在机翼结构中的应用,试验分析了柔性翼肋结构的变形效能。推断分析了机翼几何参数(翼面积、展弦比、尖稍比、后掠角)对机翼升阻特性的影响,结合柔性翼肋在机翼中的应用,优化了机翼参数和相应的后缘柔性变形量。实验证明柔性机翼结构的可行性,性能评估证明柔性机翼具有一定的优势。
【Abstract】 For the application of compliant airfoil in wing structure,an experiment was done to analysis the morphing efficiency of rib structure.Deduce and analysis of effect of preliminary wing geometric parameters(Area,aspect ratio,tip ration,sweep angle)on Lift-drag ration was done,these parameters of a high altitude long endurance UAV wing plus trailing edge morphing angle of wing were optimized.The experiment indicated a feasible flexible wing structure,and the performance evaluation proved the beneficial of flexibility of wing structure.
