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。Abstract: Thebackgroundofdevelopingthree-stagegasguntechniquedrivenbycompressed-nitrogen forlaunching8km/sprojectileswaspresented.Theeffectsofsubstitutingatwo-stagecompressedgasgun withathree-stagecompressed-gasgunonelevatingprojectilesvelocity werebrieflydescribled.
