| 摘 要： | 为了解鸟类翅膀折叠运动的作用,对一个专利中的折叠扑翼机构进行了数学建模,外翼的折叠运动由非定常过程中的气动力、弹性恢复力矩和惯性力决定.利用风洞试验和数值模拟两种方式对该折叠扑翼模型进行了研究.数值模拟和风洞试验结果表明:相对于非折叠扑翼,折叠翼能够有效提高平均升力；在一定范围内增加内翼扑动频率可以提高折叠翼平均升力系...

| Abstract: | Because of the potential use of micro air vehicles,the flapping wing mechanism has generated a great deal of interest.To understand the effect of the flexure of bird wings,a mathematical model of a patented flapping wing with a wing flexure is built and then investigated systematically by a wind tunnel experiment and numerical computation.In the computation the deflection angle of the outer wing is decided by the unsteady aerodynamic forces,the elastic moment and the inertia force.The experiment and computa... |
