本文介绍利用脉冲X射线对膛内射击现象进行测试的方法,给出用脉冲X射线拍摄的膛内燃烧的火药及其流动情况的部分照片。对底火与中心传火管两种不同点火方式对药床运动的影响进行了比较,发现了在火炮发射过程中火药基本停留在药室内燃烧等重要现象,并分析了照片上所获得的火药燃烧时的膛内问题。 This paper introduces the method of testing the shooting phenomenon in the bore by using the pulse X-ray, and gives some photos of the gunpowder burning in the bore and its flow by the pulse X-ray. The effects of two different ignition methods of bottom fire and center fire tube on the movement of the bed were compared. It was found that the powder stayed in the interior of the chamber for a long time during firing. The burning of the powder was also analyzed When the breech problem.
