Experimental technique of high velocity gas gun driven by compressed nitrogen

文章介绍压缩氮气驱动的二级气炮、三级气炮的研制背景、设计技术和发射性能特点,分析活塞质量、弹丸质量、驱动气压和泵管初充气压等发射参数对发射弹速和发射效果的影响,分析了制约提高弹速上限的主要因素,还介绍利用上述二级气炮和三级气炮开展的若干实验研究情况,评估压缩氮气驱动多级气炮的开发应用前景。

The background of developing two-stage and three-stage gas guns driven by compressed nitrogen is discussed, and the design technologies as well as their performances are analyzed. The effects of the mass of piston and the mass of projectile on the velocity of the projectile are analyzed, and the effects of the chamber pressure and the pressure of the pump tube on the velocity of the projectile are discussed. An experimental study of two-stage and three-stage gas guns is carried out. The future developing prospect of multi-stage gas guns driven by compressed nitrogen is assessed.
