Trajectory Simulation Of Air Defense Missile Visualization

This article based on analysis for the trajectory of antiaircraft missile as foundation, use OpenGL3D graphics library studied the visualization ballistic simulation techniques in the platform of C++Builder. The main work of this article is as follows:(1) Through the analysis of the kinematics foundation of missile, studied the3D trajectory of antiaircraft missile. The trajectory is divided into vertical launch phase, turn phase, guidance phase, missile/target encounter phase. We analysed the ballistic characteristics of every phase, and then established the mathematical model of the ballistic simulation.(2) Based on the2D proportional navigation, deduced the menthod that through double plane decomposition and synthesis to realize3D proportional navigation.And then analysed some key factors which influence guidance trajectory.(3) Study the fuze detection model and the movement of fragment,and then establish a calculation model of fuze delay time, we applied the model to the visual ballistic simulation.And then analysed some important parameters which influence the synergetic ability of fuze-warhead.(4) According to the trajectory model and fuze detonating model,based on C++Builder software platform and OpenGL3D graphics library as the foundation,developed a visual simmulation software, then make the visual simulation in different conditions by the software for many times,and then qualitatively analysed some keyfactors which influence guidance trajectory and synergetic ability of fuze-warhead through the result of simulation.
