膨胀波火炮内弹道初步研究

Preliminary Research on Interior Ballistics of Rarefaction Wave Gun

膨胀波火炮是在保持弹丸炮口速度不变的情况下,提前开启闩体使发射药气体后喷,从而大幅度减小火炮的后坐动量的一种新发射原理。该火炮是解决火炮系统威力和机动性矛盾的一次革命性变革。应用两相流内弹道理论,针对某口径火炮发射过程建立了理论模型,并进行了数值模拟,给出了开启闩体后波的传播的运动规律,指出了该火炮减小后坐动量应采取的措施。

The rarefaction wave gun （RAVEN） is a new type of theoretical artillery, this kind oi the gun opens the breechblock ahead of the schedule to let the propellant gas blast backwards so as to greatly reduce the recoil momentum, and also to keep muzzle velocity invariability. It is also a revolutionary transformation to solve the conflict between the gun system power and maneuverability. Two-phase flow interior ballistics model of a kind of caliber was established, and the numerical simulation was also carried out. The motion characteristics of wave propagation after opening the breechblock was given. At last, the research results pointed out the adopted measures to reduce recoil momentum.
