卡拉什尼科夫一招解决了AK47枪口上跳问题,士兵却被“打脸”

卡拉什尼科夫冲锋枪和他的AK47在战争结束后的几十年里对世界产生了持续而深远的影响,今天它可以说是着名的。然而,事实上,大多数人对AK47的理解相对较浅。将AK47的弟弟 AKM识别为AK47并不罕见。甚至AKM的恐怖分子输出也被直接归类为AK47。事实上,AKM是世界上最大的枪支生产型号。

从外面看,这两支枪实际上差别不大。枪的结构几乎相同。当时,苏联军方提出了AK47后继车型的主要目的,即降低生产成本,提高生产能力,并用铆钉机代替铣床。此外,AKM和AK47外观的最大区别应该是枪口。 AK47是一个圆柱形枪口,AKM看起来像是被斜切了。这把刀也非常特别,不是直冲,而是向上倾斜。

这种设计是卡拉什尼科夫增加的一种补偿器,用于减少连续射击过程中AK47在枪口上的严重跳跃。这是从AK47的原则开始的。 AK47是一种长冲程活塞式空气导向自动步枪。当子弹被发射时,火药气体被用于进入枪管上方的空气引导室,并且推动杆状活塞进行长行程运动以完成解锁和脱壳。重新进入,将子弹推入锁环,锁环。在重新进入过程中,由于枪的旋转,产生向上的左手力(朝着枪口的方向看)。活塞长行程对枪重心的变化和影响,以及这个向上的左手力矩,成为连续射击时枪口跳跃的原因。

In view of the serious jump of the AK47 muzzle, you can't say that the black uncle is not the right way to hold the gun. After all, Li Xiangyang is also shooting like this.

This design of the AKM expands the gunpowder gas as it rushes out of the muzzle, creating a downward-right moment to the compensator, which counteracts the AK's own left-to-left moment. Therefore, the AKM's gun jump problem is much better than the AK47.

The AKM compensator ensures that the gunpowder exit produces a torque to the lower right.

However, this compensation action actually has the problem of compensation. That is to say, although the problem of jumping up is solved, the torque generated by the expansion of the gunpowder gas is larger than the torque on the left side of the gun, which causes the problem of the buttocks hitting the face. In addition, due to this asymmetrical slit design, the gunpowder gas is sprayed to the right, which basically dispels the left-handed gunman. The AK series has a large recoil and a serious jump on the muzzle. The real solution is to wait until the AK74. The AK74 adopts a structure similar to the muzzle impact type retractor. It can use the expansion of the gunpowder to impact the muzzle to generate forward force. There are also 3 small holes in the back. The gas is ejected from the small hole, causing backlash and further reduction. The small recoil, plus the bullet of 5.45mm diameter, has a small volume of the drug chamber, and the recoil force itself is low, so the shooting accuracy of the AK74 is much better.
