摘　　要：介绍了一种新型的迫击炮灭火弹,以其为研究对象,建立了灭火弹弹丸质心运动的外弹道数学模型,并运用四阶龙格-库塔算法对外弹道数学模型进行计算,最后利用MATLAB软件对迫击炮灭火弹的外弹道进行仿真,得到了相应的仿真结果和分析结果。为提高灭火弹的射击精度以及灭火弹的优化设计提供依据。This paper introduced a new type of mortar fire-extin- guishing bombs and put it as a research object, established the grenade outside ballistic mathematical model of the projectile centroid movement, using the fourth order runge-kutta method to calculate external trajectory mathematical model. Finally, used MATLAB software to mortar fire bombs external ballistic simulation, and obtained the results of the corresponding simu- lation and the analysis. This has an important significance for improving the fire-fighting accuracy, and also provides an im- portant basis for the optimization design in the future.
