摘　　要：脉冲力的瞬间作用会引起攻角和侧滑角的急剧变化,对末修弹飞行稳定性产生较大的影响.以线性化运动微分方程组为数学解析手段,对末修弹脉冲作用稳定性进行深入分析研究.数值仿真表明,采用小扰动法分析弹丸脉冲控制弹丸飞行稳定性是可行的.The abrupt change of attack angle and slide slip angle caused by instantaneous impulse affects greatly the flight stability of terminal traj ectory correction proj ectile.In this paper,the linearization differential equation is adopted as a mathematic tool for studying the effect of im-pulse on the stability of terminal traj ectory correction proj ectiles.The numerical simulation indi-cates that using minimal disturbance method to analyze proj ectile impulse control for the terminal traj ectory correction proj ectile flight stability is feasible.
