摘　　要：为了给埋头弹内弹道设计提供理论依据,研究了埋头弹装填参数变化对内弹道过程的影响。基于两次点火及火药程序燃烧控制技术,开展了35mm埋头弹火炮内弹道性能试验,并建立埋头弹两次点火的内弹道理论模型,计算值与实测值吻合较好。在此基础上,分析了主装药装药量、弹丸质量、药室容积、火药力等参数变化对埋头弹火炮内弹道性能的影响,研究结果对指导埋头弹火炮内弹道设计有一定的参考价值。To provide theoretical foundation for interior ballistic design of cased telescoped ammunition（CTA）gun,the influence of loading parameters variation of CTA gun on the interior ballistic process was studied.Based on the second ignition and combustion control technology of gunpowder,the properties experiments of interior ballistics of 35 mm CTA gun were carried out,and the interior ballistic theoretical model of second ignition was established.The calculated result is in good agreement with the experimental result.On this basis,the effects of multi-parameters including main charge loading dose,projectile mass,chamber volume and gunpowder force on the interior ballistic properties of CTA gun were analyzed.The results offer valuable reference for the design of interior ballistics of CTA gun.
