Speaking of the new anti-personnel enhanced version of the grenade, it also benefits from the results of the improved anti-infantry mines, since Bai Yi received the emergency production of anti-infantry mines from the Ordnance Department, Bai Yi immediately put into the production of the equipment without stopping, but it didn't take long for him to stop, as for the reason, it was both simple and helpless, that is, the iron nails used up as anti-personnel fillers.

Faced with this situation, Bai Yi was ruthless and prepared to go to the steel ball killing projectile in his previous life, a few grams of metal projectiles, densely arranged together, once exploded, it was like a meteor shower, killing all the enemies, its power is so great, the effect is obvious, far from being comparable to temporary fillers such as iron nails.

Therefore, Bai Yi did not stop doing two things, ready to upgrade the anti-infantry mine to the extreme in one step, but the so-called ideal is very plump, but the reality is very skinny, when Bai Yi integrated the idea into reality, only to find that in the previous life, the metal projectile that was so simple that it only needed to press a button and spilled from the machine like a bamboo tube pouring beans turned out to be a difficult technical difficulty to overcome in today's situation.

Not to mention the Baiyun Factory, even the larger Shencheng Arsenal, and even the Jincheng Arsenal in the Guannai can not be manufactured, in the words of the old fitter Master Lei: "Such a small ball, not only the particles should be small, the surface must be smooth, not only need superb smelting technology, the craftsmanship on the machine tool must also be quite exquisite, and more importantly, there is a mold, not only to withstand high temperatures, but also not too small, this kind of processing if you manually rush to make one or twenty OK, but you can move to tens of thousands, hundreds of thousands, that is really difficult, it is too difficult!" ”

After Master Lei said this, coupled with the actual verification, Bai Yi finally found that this kind of metal projectile is indeed unachievable at the current level, which is like the balls in the ballpoint pen in the previous life, at that time, China could make it by itself, from spaceships to deep-sea submarines.

But it is such a small ballpoint pen rollerball can not be produced, all need to be imported, the reason is still that sentence, processing is difficult, the process is not good. After several years of research, the final development of the domestic ballpoint pen ball, today's metal projectile is like the ballpoint pen ball in the previous life, not a grit of teeth can be made, it requires a lot of investment, research, and even industrial upgrading to complete.

So I went around a big circle, and finally returned to the starting point, but the problem is that even the cost of iron nails is not low, and if the iron nails are used as lethal fragments, the weight of the entire anti-infantry mine is a bit heavy, and it is good if there is an army with motorized mobility such as locomotives.

But at this time, our army, not to mention the motorization of wheels all over the ground, even the mule and horse with four hooves are a little reluctant, and the mobility of the troops completely depends on the two legs under the body, and this requires that the weapons and equipment must not be heavy, otherwise they cannot be carried at all, so the contradiction between increasing lethality and controlling weight is placed in front of Bai Yi.

If other people encountered this problem, it is estimated that they would have collapsed long ago, but fortunately, Bai Yi is an outlier from the soul of the 21st century, similar to this kind of ammunition prefabricated fragmentation structure, even if you don't make a draft, you can say seven or eight kinds, and if you want to find a low-cost, simple manufacturing, moderate weight and not weak lethality, it is naturally easy to find.

As the name suggests, prefabricated fragments are independent individuals such as metal projectiles and iron nails, which form evenly dispersed fragments when they explode, so as to increase the killing efficiency.

To put it bluntly, this structure is not a separate individual, but a semi-monolithic structure connected to each other, but when the charge explodes, this semi-whole structure will disintegrate under instantaneous high pressure, forming an independent individual scattered and flying, forming a killing effect equivalent to that of the prefabricated fragment.

The semi-prefabricated fragmentation material selected by Bai Yi is very simple, that is, ordinary steel wires, and then use a simple stamping machine to evenly stamping the steel wires out of fixed expansion protrusions, and then evenly stack the processed steel wires at the front end of the charge of the anti-infantry mine, and seal it when the number reaches a certain level, and an anti-infantry mine will be officially completed.

The principle of the new grenade is the same as that of the anti-infantry mine, that is, the outer layer of the charge is wrapped several times around such a stamped steel wire semi-prefabricated fragment, and a layer of iron shell is covered to form a grenade with huge lethality.

Because the killing principle of the traditional grenade is to detonate the charge, so that the shell is instantly shattered to form scattered and splashed fragments, so as to cause damage to the target, such a grenade is simple and practical, but the problem is that the fragments are not uniform when the shell bursts, and the number of fragments is not very much, so the killing power and killing radius are not large.

So some people thought of carving prefabricated grooves on the cast iron shell of the grenade, so that after detonating the charge, the fragile grooves were instantly torn apart, and uniform fragments would come out, but the effect of this statement was good, but the groove should not be too dense, otherwise the entire shell would be extremely fragile, not to mention, the explosion effect may be counterproductive.

Weapon designers think about it, or the inside of the grenade imitation of prefabricated fragments is the best, not only evenly distributed, but also the charge is not large, but the power is much stronger than the traditional grenade, because of this, after entering the 60s of the 20th century, grenades in various countries are almost developing in the direction of built-in prefabricated fragments.

The same is true in China, where the Type 70 grenade is a wooden-handled grenade with prefabricated fragments, while the Type 82 grenade is a dual-purpose offensive and defensive grenade that uses prefabricated fragments of steel balls.

Bai Yi didn't have the time to develop a new grenade, he just used the wooden handle grenade commonly equipped by our army to modify, the weight is slightly larger than the basic type, but the lethality has increased at least three times, but because of this, the killing range is not easy to control, if it is not used properly, it is easy to accidentally injure the thrower, so although Bai Yi made this lethality enhanced version of the grenade, but he did not report it for installation, and the reason is this.

"It turns out that this is the case, but I don't think this problem matters, since this new grenade has three times the power of the traditional grenade, you may have to pay more attention when attacking, but if you play defense or block, the powerful new grenade is a good thing, you must know that our army's artillery configuration is not strong, it is completely dependent on the infantry to rush and kill, if there is a grenade to enhance the firepower of the infantry again, then for our volunteers, its significance is immeasurable......"

After listening to Bai Yi's explanation, Li Youfu's eyes suddenly lit up, as he said, he really found an immeasurable piece of equipment......
