仿生飞鱼空中飞行路径的相关研究

Relevant Research on Gliding Trajectories of Biomimetic Flying Fish

自然界的飞鱼可以自如地从水中潜行过渡到空中飞行,并在空中无动力飞行几十米远,具有绝佳的气动特性。主要研究飞鱼在空中的飞行路径问题,气动数据借鉴了前人的风洞实验结果。建立了飞鱼的三维模型,推导了飞鱼飞行的运动方程,编程求解了不同情况下飞鱼的飞行轨迹。通过调整运动参数,找到了水平飞行距离的最优解,所得结论与生物学家现场观测数据吻合较好。

This paper aims to study the flight trajectories during the gliding phase,based on the aerodynamic data obtained by the previous experimental studies in a wind tunnel.Here,the three-dimensional model of a flying fish are built,and the kinetic equations for the flying fish are proposed.which are solved with varying parameters.By varying the kinetic parameters,this paper finds the optimal solution for the gliding distance,which is consistent with the observations by biologists.
