摘要
为了掌握大口径低膛压火炮初速或然误差的影响因素,建立了某大口径火炮两相流内弹道模型并完成了数值模拟。通过模拟装药分布、弹丸挤进过程、点火过程对火炮初速的影响,了解各种装药因素对火炮初速或然误差的影响程度。所得结果为进一步优化装药结构,提高初速稳定性提供参考。
The probable error of muzzle velocity in a large caliber low-pressure gun is often influenced by propellant spatial distribution,engraving procedure and ignition process.In this paper are presented the two-phase flow interior ballistic model and numerical simulation for aspects that influence probable error of muzzle velocity.The results can be used to optimize the propellant charge of a large caliber lowpres- sure gun,and to improve MV stability.
