【摘要】 在25 mm二级轻气炮上进行了火药室与泵管之间有、无大膜片的实验研究,观察在相同装填参数下这两种发射的弹道差异。理论计算和实验结果表明,火药室和泵管之间有、无大膜片对弹道性能没有明显的影响。更多还原

【Abstract】 Experiment was done to study on the effect of big diaphragm between powder chamber and pump tube in two-stage light gas gun with diameter of 25mm.The differences of interior ballistics with diaphragm and diaphragmless are observed at the same filling parameters.Theoretical calculation and experimental result indicate that the effect of big diaphragm on interior ballistics is not evident.更多还原
