摘要
针对激光末制导炮弹在高海拔地区的弹道特性变化,对其在不同阵地高程条件下的角运动特性进行了研究。建立了系统全面的激光末制导炮弹外弹道模型,对不同阵地高程条件下的激光末制导炮弹外弹道进行了模拟仿真。通过仿真计算分析了不同阵地高程条件下的激光末制导炮弹角运动特性,研究了角运动特性在不同阵地高程下的变化规律。结果表明,以阵地海拔0 m的角运动数据为参考,阵地海拔5 000 m时,在惯性控制段和导引控制段,弹道倾角增加约10%~15%,速度偏角数值总体增加2.75~2.86倍以上;但在导引控制段出现了大幅低频的周期性俯仰和偏航运动,导引控制段俯仰角幅值平均增加约7倍、频率平均减小约6倍,偏航角的幅值平均增加约12倍,频率平均减小约7倍;且攻角范围由0.8°增至4.9°,侧滑角范围由2°增至4.7°,角运动加剧。建议改进该弹的控制系统,以增强该弹在高海拔地区的适用性。
In response to the changes in ballistic characteristics of laser-terminal guided artillery shells in high-altitude areas,the angular characteristics under different elevation conditions were studied.A comprehensive external trajectory model was established,and simulations conducted under different elevation conditions.The angular characteristics were analyzed through simulation calculations,and the variation laws of angular characteristics were studied.The results showed that,based on the angular data at 0 m,at 5000 m,the trajectory inclination angle increased by about 10%~15%in the inertia control section and the guidance control section,and the overall value of velocity deviation angle increased by more than 2.75~2.86 times.However,there were significant low-frequency periodic pitch and yaw movements in the guidance control section.The pitch angle amplitude increased by an average of about 7 times and the frequency decreased by an average of about 6 times in the guidance control section.The yaw angle amplitude increased by an average of about 12 times and the frequency decreased by an average of about 7 times.The range of attack angles increased from 0.8°to 4.9°,and the range of sideslip angles increased from^(2)°to 4.7°,resulting in increased angular motion.It is suggested to improve the control system to enhance its applicability in high-altitude areas.
