38毫米催泪子母弹增程设计及弹道仿真

Study on Extended-Range Design and Ballistics Simulation for 38mm Multiple Tear Bomb

在子母弹射程优化控制问题的研究中,射程是武器系统重要战术性能指标,增加射程可有效提高武器作战性能。在分析子母弹射程、弹丸初速及装药量三者关系的基础上,针对38毫米催泪子母弹发射器出口速度较低导致的实际射程较近(<100米)及无法达到预期战术技术指标的问题。由于传统发射器出口初速度低,性能差。为此提出用数字仿真的方法,在MATLAB上进行弹道模型仿真,仿真出子母弹的弹道曲线。仿真结果表明,在保持药室容积不变的情况下,增加装药量,可提高子母弹初速,进而增大射程。通过计算机仿真射弹过程中的大量随机因素,相当于在计算机上打靶,所得结果具有较高的可信度和精度。以某型38毫米催泪子母弹为实例,结果表明,方法精确、简单实用,可为子母弹射程优化设计提供参考。

Range is the important tactical measures of the weapon system, extended - range can effectually improve the combat effectiveness. Based on the description of the composition and launch theory of the 38mm multiple tear bomb and the analysis of the relationship between the range, charge density and muzzle velocity of projectile, in order to solve the problem of the short reality range of 38mm multiple tear bomb and the problem that it can not achieve the anticipation of tactical measures, taking numerical simulation and the software MATLAB as basic computa- tional tools, its ballistics curves were obtained, which leads to a conclusion that increasing the charge density can improve muzzle velocity of projectile of the multiple launcher for its extended - range. A large number of random factors can be simulated in computer just like shooting in the computer and the result has higher credibility and precision. Taking a new 38mm multiple tear bomb as example, the result indicates that this method is accurate and practical.
