THE INTERIOR BALLISTIC PHYSICAL MODEL AND ITS NUMERICAL SIMULATION IN 30MM PLASMA-AUGMENTED SOLID PROPELLANT GUN

提出脉冲形成网络（ＰＦＮ）控制电能释放条件下的固体发射药电热化学炮内弹道模型，采用１ＭＪ贮能电源，对３０ｍｍ电热化学炮（ＥＴＣＧ）进行了弹道计算。计算中改变的参量有电能输入量、电能与化学能的匹配关系、药室容积、身管长、装药量及弹丸质量等。最后给出了不同参量组合所能达到的最大火炮效能，从而为该武器设计提供了理论依据。

In this paper. a interior ballistic model of solid propellant electrothermal chemical guns is proposed, in which the releasing rate of electrical energy is controlled by pulse forming network.Total electrical energy stored in power source is 1 MJ.The interior ballistic process of 30 mm ETCG is simulated,in which the ballistic parameters may be djusted such as the input values of electrical energy, the match relation between electrical energy and chemical energy, the volume of chamber,the length of barrel.the mass of propellant and the mass of projectile.The optimum ballistic efficiency obtained by the difference combination of ballistic parameters is proposed in the end.It may provide theorotical principle for the designation of this kind weapon.
