摘    要:介绍了一台57mm口径一级压缩气炮驱动的10mm口径二级轻气炮,并分析了这种气炮的特点。对其发射参数和发射效果之间的关系进行了数值计算模拟,计算弹速与实测弹速的差异小于10%。根据计算模拟结果,分析了活塞质量、活塞驱动气压、泵管初充气压和弹丸释放气压等发射参量同弹速和二级气室的气压气温峰值的关系,评估了10/57二级轻气炮的发射能力。

关 键 词:轻气炮  高速撞击  发射  弹丸  发射参数

Abstract:A 10mm calibre two stages light gas gun driven by a 57mm calibre compressedgas gun is introduced and its special feature is described.Adigital simulation is used to describedthe relation of launch parameters and the results,the difference of pellet speed between computedand measured is less than 10%. The effects of pressure for driving piston,mass of piston,origi-nal gas pressure in pump tube and release pressure for pellet on speed of pellet as well as peakpressure and peak temperature in the chamber are analysed.The capability of 10/57 two stageslight gas gun is evaluated.
Keywords:gas gun  light gas gun  high speed impact  launching  bullet
