鸽状扑翼飞行器气动特性研究
|
摘要
参照典型鸽子翅翼的参数特征,构建鸽状翅翼模型并得出扑翅角度函数。而后借助Fluent软件,采用动网格技术,对扑翅过程中的流场状态进行数值计算,得到了翅翼扑动中的升力、阻力变化特点;基于仿真得到的升阻力系数曲线,分析扑翅运动过程中升阻力变化特征,并从不同角度展示并分析了翅翼扑扇过程中涡的动态过程。分析了升阻力系数随攻角的变化特性,并以实际鸟类飞行姿态为对比依据,证实仿真结果的合理性。
The paper constructed a pigeon wing model with reference to the parameters of the typical wing,and the angle function of the wing was obtained. With the help of Fluent software,the dynamic grid technology was used to calculate the flow state of the wing in the wing process. The characteristics of the lift and drag change in the wing flapping were obtained. Based on the curve of lift-drag coefficient obtained by simulation,the variation characteristics of lift-drag coefficient in the process of flapping wing movement were analyzed,and the dynamic process of vortex in the process of flapping wing was displayed and analyzed from different angles. The variation of lift-drag coefficient with angle of attack was analyzed,and the rationality of simulation results was clarified by comparing the flight attitude of birds.
