作为职业军人,不管是罗凯还是庞正清太明白这其中的不易了,所以才会这么的惊讶。
解释完这些,吴浩这才回答庞正清的问题。
“电磁枪不是利用化学能作为推进剂来发射弹头的,因此不需要弹药,也不需要弹壳,只需要一枚弹头。子弹在整个枪管内它其实是处于一个持续加上加速状态,而不是因为弹药燃烧瞬间加速状态,所以它对于气密性的要求很低。
不但不要求气密性,反而还会要加大空隙,这样有利于持续高速设计时候所散发的巨大热量,所以我们的枪管其实是属于一种镂空状态的。
与其说它是枪管,不如说它其实就是一个发射轨。它有数条圆形钢轨构成,上面有石墨滑块,将会极大的减少子弹在滑行加速状态所产生的摩擦力。
一方面能够减少滑行摩擦所产生的热量,另外一方面和能够提升弹头在发射时候的稳定性,提升它的设计精度。
其实它的原理很简单,倒是有点像是我们坦克的滑膛炮原理,这种弹头也有点像是坦克炮所使用的稳定脱壳钨芯穿甲弹。”
介绍到这,吴浩拿起了那把加长型的精确射手步枪,然后拆掉了弹匣,里面赫然出现了和前面暗中水滴流线型弹头差不多的弹头,只不过在弹头的尾部还有一个看上去是塑料的尾翼。真的如吴浩所说,跟坦克的脱壳稳定钨芯穿甲弹非常像。
“这两种子弹一样的吗?”罗凯不由的询问道。
吴浩笑着点了点头:“其实是一样的,只不过一个有这种尾翼,一个没有尾翼罢了。它们其实在近距离设计时候的差别不大,比较大的还是在中远距离方面。
这两种子弹我们也都还在实验阶段,不过未来成品应该都会换成这种带塑料尾翼的子弹。虽然是增加了一个塑料尾翼,但是它的成本也没有增加多少,而且整体重量也没有重多少,只有几克十几克,基本上可以忽略不计。”
介绍到这,吴浩从弹匣里面推出来了一枚子弹然后拿在手上展示给二人说道:“相比于传统弹头,这种弹头更加符合空气动力学设计,因此它在空中的飞行姿态更加稳定,弹道也更加笔直。
并且它受空气湿度,风速的影响要相比于传统子弹要小一些。”
而罗凯和庞正清呢也终于是近距离看到了这种子弹的全貌,它正如吴浩所说是水底形状,和传统的步枪弹弹头整体上差的不多,但是细节还是有很大的。
比如整体呈现明亮的金属银色,弹头尾部收缩细长,上面套了个塑料尾翼。如果不是从枪械弹匣中拆除来,换着别处,不管是罗凯还是庞正清都以为这是什么小孩子的玩具呢,压根想象不出来这会是一枚能够杀人的子弹。
