摘要
对基于质量矩技术的机动弹头再入性能进行了探讨。首先建立了弹头的空间运动数学模型;然后在此基础上根据再入段特性对运动方程作了适当简化并计算了弹头内部质量块分别处于静止、瞬时置位、线性平动这三种运动状态下的落点参数;最后分析比较了质量块运动的变化对机动范围的影响。仿真结果表明了质量矩技术作为弹头再入机动控制方式的可行性。
The reentry performance of moving-mass actuated kinetic warheads is discussed in this paper, Firstly, a mathematical model for warheads＇ spatial movement is founded. Secondly, the kinematic equations are simplified on the basis of reentry period characteristics, and then the fall points corresponding to the inner moving-mass three movement states, including rest, instantaneous placement and linear translation, are respectively calculated. Finally, the kinetic ranges induced by change of mass movement are analyzed and compared. Simulation results indicate that moving-mass technique as a reentry-kinetic controlling method for warheads is practicable.
