基于电磁发射技术发射大口径深弹武器,为设计并获得其外弹道特性,建立深弹弹道模型通过四阶龙格-库塔法解算弹道方程。仿真分析最大射程角等弹道参数,得到了初速与射程对照关系;研究了初速误差和风速对外弹道的影响;探究压心相对位置对稳定性的影响。仿真结果表明了深弹外弹道初步设计和仿真分析方法的有效性。

Launch large-calibre suspended depth charges based on electromagnetic emission technology,establish a suspended depth charge model,solve the ballistic equation by the fourth-order Runge-Kutta method to design and obtain its external ballistic characteristics.The maximum range angle and other ballistic parameters were simulated and obtained.The relationship between the muzzle velocity and the range is framed.The influence of the initial velocity error and the wind on the external ballistics is studied.The influence of the relative position of the pressure center on the stability is investigated.The simulation results show the effectiveness of the preliminary design and simulation analysis method of suspended depth charges.
