摘要/Abstract

摘要： 提高初速是身管武器技术永恒的研究主题。提出了一种具有二次加速功能的三药室发射装置工作原理，对其发射进行了实验研究。该装置特点是在身管上离主药室一定长度的水平位置，增加两个辅助药室，弹丸通过辅助药室入口处时，弹后高温、高压火药燃气点燃辅助药室装药，辅助装药燃烧产生的气体可减缓弹后空间压力下降，使弹底维持较高压力，达到弹丸二次增速目的。发射实验结果表明，该装置在不显著增加膛压的情况下，比单药室发射时平均初速提高15%左右，对工程防护终点弹道效应实验研究具有参考价值。

Abstract: How to increase initial velocity is an eternal subject matter for tube weapon technology. An operating principle is put forward for three-powder chamber launch device with secondary acceleration function, and the launch test is made. The characteristic of the device is that two accessory powder chambers are added on the barrel, which are at a distance from the primary powder chamber. When a projectile passes through the entrance of accessory powder chambers, the charges in the accessory powder chambers are ignited by high-heat and high-compressed power gas. The gas generated by accessory power burning can slow up the space pressure and keep the projectile base at high pressure, achieving the objective of secondary acceleration . The interior ballistic analysis and launch test result show that the initial velocity is increased by 15% in the case of indistinctively increased chamber pressure.

Key words: ordnance science and technology, secondary acceleration, three-powder chamber, accessory powder chamber, launch device, terminus effect
