提高点火管点火性能的一种方法

One Way of Improving Ignition Performance of Ignition Tube

根据大口径火炮金属中心点火管设计要求 ,提出了一种改善点火稳定性的方法———将黑火药压实成饼状 ,装填入金属中心点火管中 ,通过改变药饼的几何形状、压药密度来调节点火压力 ,以匹配不同的发射装药结构。

According to the demand of large caliber cannon ignition system design,combining the practice of engineering development and manufacture,a new kind of ignition powder backfill structure was proposed ,which is to put pressure on black powder and make high density caky powder,then load it into metallic center ignition. The geometrical shape of caky black power and loading density are modified to modulate ignition pressure,so as to match different propellant structure.
