针对爆炸声源子弹落点间距的要求,建立火箭外弹道和子弹抛撒数学模型,分析子弹落点随弹道高度的变化规律,研究子弹不同落点间距与爆炸声源传播损失、水中冲击波超压峰值及布放距离之间的关系。结果表明:母弹开舱点位置将直接影响子弹落点间距和布放距离。所得结论为选取合理的开舱点位置提供了参考依据。

The mathematical model of rocket exterior ballistic trajectory and ejection of submunition was established according to the required space of submunition impact points, the submunition position varying with trajectory altitude was analyzed, and the relation between impact point spacing and acoustic loss, shock wave pressure, distance was discussed. The result shows that the impact point spacing and distance is influenced directly by the carrier opening point. The result provides reference for proper opening position selection.
