摘　　要：介绍了弹速8km/s、氮气驱动三级压缩气炮技术的研究背景。论述了以三级压缩替代二级压缩在提高氮气驱动多级气炮上限弹速方面的意义。讨论了弹径10mm的57-37-10三级气炮的驱动气压、泵管初充气压与发射弹速及高压气室荷载之间的关系。简述了57-37-10三级压缩气炮主要部件的工程设计,通过实验数据和实物照片表述了57-37-10三级压缩气炮研究工作的进展情况。The background of developing three-stage gas gun technique driven by compressed-mtrogen for launching 8 km/s projectiles was presented. The effects of substituting a two-stage compressedgas gun with a three-stage compressed-gas gun on elevating projectiles velocity were briefly deseribled. The relationship between the driving pressure, the initial pressure of pump tube and the load of the pressure chamber were dissussed for the 57-37-10 three-stage gas gun. Some progress on devel- oping the 57-37-10 three-stage gas gun was shown.
