射弹散布对射击方法和火力运用等有较大影响。为了对比分析无控旋转弹丸射弹散布随高程变化的特点,以旋转稳定弹丸刚体外弹道模型(6D模型)和高海拔地区平均气象条件为基础,对某大口径榴弹不同阵地高程条件下的6D弹道进行仿真。采用蒙特卡洛法模拟分析射弹散布随阵地高程变化的规律,研究了阵地高程对射弹散布的影响。结果表明,相同射角时射弹散布随着高程增加而减小,阵地高程较大时,射弹散布性能优于低海拔条件下射弹散布。

Projectile dispersion has a great impact on firing methods and fire application. In order to compare and analyze the characteristics of the dispersion of uncontrolled rotating projectile with elevation, the 6D trajectory of a large caliber grenade at different position elevations is simulated based on the rigid external ballistic model of rotating stable projectile (6D model) and the average meteorological conditions at high altitude. Monte Carlo method is used to simulate and analyze the variation law of projectile dispersion with position elevation, and the influence of position elevation on projectile dispersion is studied. The results show that the projectile dispersion decreases with the increase of elevation at the same firing angle. When the position elevation is large, the projectile dispersion performance is better than that at low altitude.
