可机动弹道导弹三维飞行状态建模与仿真研究

为提供接近实际的弹道导弹飞行状态数据,根据弹道导弹气动特性和飞行控制原理,在实际飞行环境下,建立了可进行气动力及质心侧向力控制的多级助推弹道导弹三维飞行状态模型,并分别对单级、双级、三级助推的弹道导弹在气动力及质心侧向力控制下的飞行状态进行仿真。仿真结果表明:该模型能真实模拟质心侧向力及气动力控制的弹道导弹飞行规律,为弹道导弹拦截、突防、攻防对抗仿真等研究提供实时飞行的位置、速度等仿真数据。

Research on modeling and simulating for 3-D flight states of ballistic missiles with maneuver capability

In order to provide the almost actual flight states data of ballistic missile,a multistage boosting ballistic missile’s 3-D flight states model in true flight conditions is built up.Considering aerodynamics and flight control theory,the model controls the missile not only with missile pneumatic forces but with lateral forces acting on missile mass center.To verify the model,flight states scenarios of the missile that is single stage boosting,double stages boosting,three stages boosting,controlled by pneumatic forces and mass center lateral forces are simulated in turn.The simulation result indicates that the model can simulate the flight of true ballistic missile controlled by pneumatic forces and mass center lateral forces.The flight states data of ballistic missile are provided such as location and velocity for simulation research on ballistic missile intercepting,onrushing and scenarios ballistic missile attacking versus defending.
