装填条件对膨胀波火炮弹道设计评价标准的影响

摘要

膨胀波火炮利用发射过程中精确打开炮闩的方法实现了在不降低弹丸初速的前提下,大幅度减小火炮后坐的目的.采用经典内弹道理论对膨胀波火炮发射过程进行了建模与仿真,计算并分析了药室容积、装药量、弹丸质量等装填参数对膨胀波火炮有效功率、炮膛工作容积利用率和火药相对燃烧结束位置等弹道设计评价标准的影响规律,为膨胀波火炮弹药系统设计及实际应用提供了理论参考.%By means of accurately opening breechblock while projectile is traveling in barrel, the aim to considerably reduce recoil momentum under the presupposition condition of without decreasing the muzzle velocity of projectile is realized in the rarefaction wave gun (RAVEN). The classical interior ballistics models of RAVEN is set up and simulated. The influences of such parameters on effective power, barrel work spaces efficiency and relative end location of propellant combustion are analyzed, as chamber volume, charge mass and projectile mass. Theoretical reference is provided for practical application of RAVEN.
