舰载无人机起飞动力学研究与仿真

舰船搭载无人机不是简单的"无人机和舰船"组合,而是一项复杂的系统工程.海上和舰上的情况与陆地有很大差别,海浪特性、舰船运动、舰船空气尾流场、舰面建筑物和设备都直接影响到机-舰动态配合特性.无人机的舰上起飞是研究机-舰动态配合的主要内容,它是无人机起飞安全和充分发挥其潜力的有力保证.为此利用频谱分析方法得出海浪中舰船的摇摆运动规律,并把舰船运动、海面风场及舰船尾流的影响加入到无人机的运动方程中进行建模仿真,研究了舰船运动及海面风场影响下无人机从舰船起飞的动力学特性,并得出其安全起飞的基本条件.

Research and Simulation of Unmanned Aerial Vehicle Onboard Take-off Dynamics

Shipborne Unmanned Aerial Vehicle(UAV) is a complex engineering system instead of a simple combination.The conditions on the sea or ship is different from the land conditions.There are many factors influencing UAV/ship dynamic compatibility such as characteristic of ocean wave,building and equipment on ship,motion of ship and ship air wake.Studying the take-off of the UAV from a ship is the basic contents in studying the dynamic compatibility of the UAV and the ship.It ensures that a ship-borne UAV can take-off safely from a ship and that a UAV can give its operation effectiveness to full play.By the means of frequency-domain analysis,the motion of ship in sea wave is simulated.And with the result of simulation based on the motion of ship,wind field,ship air wake and dynamics equation of UAV,this paper studies the dynamic performance of UAV during take-off from a ship.At last the paper gives some conditions which can affect the take-off of UAV from a ship.
