弹丸初速可调的电磁轨道炮对空射击策略

Antiaircraft Firing Strategy of Electromagnetic Railgun with Adjustable Muzzle Velocity of Projectile

基于电磁轨道炮射弹速度可调的特点,研究其对视距内空中目标的射击策略。建立弹丸六自由度外弹道运动方程组以及弹丸对空中目标单发射击、全航路连续射击时的命中概率模型,系统分析单发射击、全航路连续射击下目标距离、弹丸初速对命中概率的影响。结果表明:单发射击下弹丸初速越大,目标命中概率越大;全航路连续射击下,累积命中概率随着弹丸初速增大,整体趋势上先增大、后减小,但存在局部阶跃下降现象;由近及远、有效射程内单发命中概率最大、射击远界上多发同时弹着的全航路平衡射击策略可兼顾全航路累积命中概率和舰炮打击成本,以较小的打击成本获得较优的作战效能。

The firing strategy of electromagnetic railgun against an air target within line-of-sight range is studied based on the adjustable characteristics of projectile speed.A 6-DOF exterior ballistic equation set and a hit probability model for single-shot and whole-route continuous-shot firing on air targets are established.The impacts of target distance and muzzle velocity on hit probability in the cases of single-shot firing and whole-route continuous-shot firing are analyzed.The results show that,during the single shot firing,the higher the muzzle velocity is,the higher the hit probability is.In the whole-route continuous-shot firing,the cumulative hit probability increases first and then decreases with the increase in muzzle velocity,but there is local step-decreasing phenomena.A whole-route balanced firinging strategy,which is from the near to the distant,the highest single shot hit probability within effective range and multiple multiround simultaneous impact on the far side,can take into account the whole-route cumulative hit probability and the naval strike cost,and obtain a better operational effectiveness at a lower strike cost.
