Super Weapon Swap System

In later generations, it can be seen that in every military operation and external deployment of the eagle country, their soldiers are almost fully armed. The eagle soldiers in the Hummer almost become the symbol of war. They all wear this kind of vest with bulletproof insert plate inserted inside.

These bulletproof inserts have also saved the lives of many of their soldiers. Of course, many of them were produced by the Han country. In later generations, the Han country is also a big country in this regard.

However, it is rare to see the soldiers of the Han country wearing this bulletproof plug board. Of course, there is a reason. The Han country is a big country and the number of army ranks first in the world. If all of them are equipped with this thing, it is definitely a high one-time investment.

Moreover, behind the bulletproof insert plate, there are a lot of nylon soft protection. That thing has a long life. After a few years, the effect is poor, so it can't play a protective role, so it has to be replaced again.

The threat of a large-scale war on land in the Han country is very small. Therefore, it is not necessary for the Han Army to equip in large quantities, and a small amount of equipment is enough for elite troops.

In the Han Dynasty, so many state-owned enterprises produce and export to the world. Therefore, once necessary, they can also produce a large number of bulletproof insert plates at any time to equip soldiers.

Among all these insert plates, the front is ceramic, and ceramics are divided into different types. The common ones are alumina ceramics, silicon carbide ceramics and boron carbide ceramics.

Among the three, alumina ceramics have the highest density, but the hardness is relatively low, the processing threshold is low, and the price is relatively cheap.

Therefore, it occupies the low-end market. Although it weighs half a kilogram, the price is only half that of silicon carbide and one sixth that of boron carbide.

Now, Niu Guo started to make this kind of material. After all, we should first solve the problem of whether there is one or not and confirm the performance.

Silicon carbide has moderate density and relatively moderate hardness. It belongs to the middle nature and has high cost performance. Therefore, those who pursue cost performance will use silicon carbide ceramics.

Among these ceramics, boron carbide ceramics have the lowest density and the highest strength. At the same time, it also has high requirements for processing technology and needs high temperature and high pressure sintering. Therefore, its price is also the most expensive among several ceramics and is absolutely exclusive to local tyrants.

(low density means light weight, high strength and strong anti Strike ability.)

Different bulletproof insert plates can achieve the same protective force, that is, the weight is different. However, if you carry one or two kilograms more, it's better than the bullet breakdown, right?

Therefore, no matter how uncomfortable it is, for example, it is so hot in the desert. If you go out for a circle, you will have hot prickles on your stomach. However, those Eagle soldiers still have to cover themselves up.

As there is no need to worry about large-scale conflicts on the ground in China for the time being, the problem of bulletproof plug-in plate will not be considered for the time being and will certainly be produced in the future. However, the selection of bullet caliber has a great bearing on it. Therefore, we must make these clear.

Of course, the plug-in board has a level division. If you want to block rifle bullets, you need NIJ III board, which is more advanced than it. Of course, the price is also high.

Now, Qin Guan talked about the development of this part, and the meeting hall fell into silence.

"Can it really stop?" someone asked.

"Practice is the only criterion for testing truth. If you have such doubts, we might as well go out and try it now?" Qin Guan said.

In the confined space, Qin Guan did not dare to do so. He was afraid of stray bullets. Here are smart minds and engaged in scientific research. Therefore, Qin Guan must do a good job in safety.

Get out, go to the shooting range.

At Qin Guan's suggestion, the meeting was suspended and several buses pulled everyone to the shooting range.

Although Qin Guan wanted to wear this suit to let people shoot the target, no one dared to do so. Even the scholar himself was denied. Therefore, the final result was that the dress was put on by the target and put on the target, and a piece of meat was padded on the inner side of the target. In this way, once penetrated, we can see what it was like to enter the meat.

"We don't need pistols. We'd better use the 5.56 mm rifle most commonly used in the eagle country first. At a distance of 300 meters, see what effect it has," Qin Guan said.

The bulletproof capability of the bulletproof insert plate is not only related to bullets, but also related to distance. 300 meters is generally the limit shooting distance of small caliber rifles. Many soldiers are not allowed to shoot at this distance.

However, it was difficult for the scholar to adjust the M16 rifle to the three-point firing position.

Although it is best to pour bullets like the AK47, countless examples have proved that there is no accuracy in continuous firing. After three rounds, the bullets have already flown. Therefore, although the early M16 rifle has the method of continuous firing, there are only two methods for the current m16a2, either semi-automatic firing, Or it's a three shot burst shot.

Semi automatic single shot shooting has no power. It's better to shoot directly from three points. Shoot three shots at once.

"Chutu." different guns have different shooting sounds. The sound of M16 has a poor texture. This sound makes people not so afraid.

After three voices, the scholar stopped shooting. Then, the target man directly carried the target and came over.

We need to see what happens.

There are three holes in the front vest cloth. In these three holes, you can see that there are three holes, which are formed by ceramic fragmentation. If you take them out by hand, you can also take out black powder. When you open the back, the warhead does not penetrate, and you can see that the meat is intact.

"Impossible, how could this be possible? The protective force is too strong?" someone asked in confusion.

"At one shot, the ceramics may break. How can they block the second and third shots?"

"Because ceramics are small pieces and stick to them piece by piece, one shot will only break one piece of ceramics." Qin Guan said: "unless it is a sharpshooter and the second shot hits the bullet hole of the first shot, it can continue to save its life."

They must see it with their own eyes. After all, this bulletproof plug-in board is NIJ III.

There are different standards for bulletproof insert plate. NiuGuo's NIJ standard is popular all over the world. This class III can withstand bullets with an initial speed of about 847 M / s and a warhead weight of 9.6 G.

And now?

For the M16 rifle, the speed of the bullet out of the muzzle is only 835 meters per second, but after flying 300 meters, the speed has been reduced to 635 meters per second. Even the upper level can be blocked.

Not to mention that the bullet warhead of M16 rifle is lighter, only 4 grams. When it goes up, the ceramics are broken, and the warhead is broken. There is no lethality at all. The back is flat, and there is no sign of penetration at all.

"This doesn't mean anything." just then, a voice said, "even if there is no breakdown, this impact can hurt people's internal organs. It's more effective for us to hurt an enemy on the battlefield than to kill an enemy."
