采用捏合—压伸—固化发泡—车加工的新工艺研制整体耐热无壳弹药柱 ,并用弹道枪测试了初速和膛压。结果表明该药柱可满足使用要求。 The whole heat-resistant shell-less ammunition column was developed by the new technology of kneading-stretching-curing foaming-car-processing. The initial speed and chamber pressure were tested by ballistic gun. The results show that the drug column to meet the requirements.
