用脉冲X射线检测膛内射击现象

X-RAY DETECTION OF PHENOMENA IN A GUN BARREL DURING THE FIRING PROCESS

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 presents a method for the X-ray detection of phenomena within a gun barrel, shows some photographs taken, revealing the combustion of propellant and motion of grains. The paper gives a comparison for the states of motion of the propellant beds with different ignition patterns (primer at bottom and central position) during the firing cycle. It is seen that the burning propellant grains basically remain in the chamber. Propellant combustion within the barrel is analysed with the help of information provided by these photographs.
