导弹飞行仿真系统可视化设计与实现

The Design and Visualization of Missile Flight Simulation System

针对导弹设计中对飞行仿真数据和舵面、喷管等动态部件实时观察的需求,设计了一种以系统仿真、虚拟现实和可视化技术为基础的导弹飞行仿真系统,先通过弹体数学仿真模型计算得到飞行仿真数据,然后通过仿真管理部分对数据进行处理和保存,最后采用三维视景显示、二维弹下点轨迹和数据动态曲线显示等方式,实现了导弹飞行系统的可视化仿真。实验结果表明,系统能够实现导弹的实时飞行仿真,能够实时观测飞行仿真数据和弹体、舵面、喷管等部件的动态变化,为导弹设计与研制提供了直观、有效的仿真手段。

To fulfill the requirement of real-time observation of the flight simulation data and dynamic components such as rudder and nozzle, a missile flight simulation system based on system simulation, virtual reality and visualization is proposed. The simulation data are generated by the mathematical model of missile and then those data are handled by simulation management. The visualization of system is realized by 3D scene displaying, 2D tracking and dynamic curve drawing. The experiment results show that this system can realize the real-time flight simulation of missile and supply the observation of the flight simulation data and dynamic components. It can be used as a simulation method for missile design and research.
