Research on waypoint flight simulation based on pilot control characteristics

基于驾驶员航路飞行任务中的操纵特性,首先对飞机横侧向、法向、切向过载的机动指令进行了设计,重点对横侧向通道机动指令的设计进行了研究,提出了一种利用飞机速度矢量与目标航路点坐标来设计偏航指令的方法;然后用差分算法实现了驾驶员实际操纵指令的平稳变化;最后对飞机的航路飞行进行了数值仿真。仿真结果表明,所提出的方法可以较为真实地实现飞机的航路飞行。在仿真过程中,机动指令的变化较为平缓,并且飞机的航迹姿态角等信息得到了实时展现。

Waypoint flight is an important part of combat mission scenarios in flight simulation. Firstly, the maneuvering commands of lateral,normal and tangential channels were designed based on the control characteristics of the pilot in waypoint flight missions,especially focused on the lateral channel,and a method based on the relationship between the velocity of the airplane and the coordinate of the target waypoint was put forward. Then the difference algorithm was used to realize the smooth change of pilot＇s actual maneuvering commands. At last,numerical simulations were performed to verify the method. Simulation results show that the method can truly realize the waypoint flight,the maneuvering commands change smoothly and the attitude angle is displayed in real-time during the simulation.
