Modeling and Simulation of External Ballistics of New Air-Defence Guided Projectile

The method of three-dimensional ballistic modeling and simulation of shipborne air-defence guided projectile is discussed. Firstly, the force and guidance law of the projectile are analyzed, and taking the proportional guidance as an example, the method establish the simulation model of the air-defence guided projectile ballistic from the perspective by dynamics. Secondly, the selection criteria of some parameters are discussed, and the three-dimensional ballistic simulation is performed by Matlab. Finally, the effects of the motion parameters such as projectile speed, target speed and proportional coefficient on the trajectory and encounter time are analyzed. The simulation results show that the method is correct and feasible, and it has certain significance for the ballistic design and optimization of shipborne air-defence guided projectile.
