基于Matlab/FlightGear的导弹飞行姿态与 轨迹可视化系统

在导弹6自由度运动学方程组的基础上构建了6自由度矩阵式运动学方程组,使用Matlab/Simulink编程工具构建了导弹的非线性6自由度矩阵式Simulink模型.利用AC3D软件建立导弹的三维物理模型,在对指定部位设置了对象名称后,将其导入至FlightGear中.最后,通过数据接口将Simulink中的仿真数据传输至FlightGear,从而控制导弹的飞行姿态与轨迹,并在FlightGear中实时显示.该可视化仿真可以多视角全方位直观地显示导弹的飞行姿态与轨迹,为导弹的可视化研究提供了便利的方法.

Missile Flight Attitude and Trajectory Visualization System Using Matlab/FlightGear

According to the matrix kinematics equations of the six degree of freedom of the missiles, the nonlinear six degree of freedom matrix flight dynamics model of missile was constructed by using the Matlab/Simulink programming tool. The AC3D software was used to set up the 3D physical model of the missile, and the object name was set up to the specified location, and then it is imported into the FlightGear. Finally, the simulation data of Simulink is transmitted to FlightGear through the data interface, which can control the flight attitude and trajectory of the missiles and display real-time display in FlightGear. The visual simulation can provide a convenient method for the visualization of the missiles.
