Military Technology

The gun was shot and smoked, which is actually not a big deal. When the gun is fired continuously, the temperature inside the barrel will soar rapidly, even reaching hundreds of degrees, and the entire barrel may burn red.

The handguard on the gun will also ignite due to high temperature, or even burn directly.

In addition, the gun oil and butter used for lubrication in the gun will burn and smoke due to high temperature, which is a normal phenomenon. Under normal circumstances, it is necessary to stop shooting at this time, let the barrel cool down naturally, or replace the barrel.

In fact, many machine guns are equipped with a second barrel, which is convenient for cooling replacement. In order to avoid this situation, people conducted research and exploration on the cooling of the gun barrel, and finally developed two technologies, which are air cooling and water cooling.

Simply put, air cooling is to use a heavy barrel and install a heat sink on the barrel to play a role in heat dissipation. In this regard, the more famous ones are the Type 92 heavy machine guns equipped by the little devils during the Anti-Japanese War, which is also known as "Bright Sword". In ", the heavy machine gun that Li Yunlong was reluctant to throw away when he broke out and retreated, it is a representative of the use of air cooling to cool down.

In addition, there are German g34 and g42 general-purpose machine guns during World War II, as well as Lao Mi's m2 heavy machine guns, all of which are air-cooled and heavy-barreled machine guns.

The water-cooled machine gun is earlier, and the most typical and representative of it is the Maxim heavy machine gun that you often see in film and television dramas. It will have a thick cylinder on the barrel. Inside this cylinder It will be filled with water so that it cools down the barrel.

During the usual march, in order to increase the weight and facilitate portability, there is no water outside the cylinder. When it comes to actual combat, it is necessary to fill the water outside. Therefore, outside the heavy machine gun squad, there will be no dedicated soldier carrying a bucket of water to prepare.

However, because the air-heated machine gun was too light, that method was gradually eliminated and replaced by the current heavy-barreled machine gun.

Wu Hao nodded when he heard Luo Kai's words, and before he took out the ammunition box and finished the gun inspection, he looked at the scrapped car nearby and said, "Come on, let's go and have a look."

The seats outside the car were also sieved by the bullets and fell apart. Not only that, even the hub of the car was punctured, and it was known who spread the rumor that the hub could stop bullets.

Luo Kai nodded slightly upon hearing this, then shook his head again.

In fact, there are no similar electromagnetic guns in the market now, but their power and performance cannot be compared with yours.

Speaking of that, Luo Kai laughed: "It doesn't matter if it's a mistake, in terms of the bone protective armor in your machine, the bullets and electromagnetic guns are still useless.

That is mainly because the initial velocity of the electromagnetic gun is too slow, and it is difficult for traditional shells to withstand such speed and force, and it is difficult to delay detonation, so the solid shells are used intelligently.

Of course Luo Kai knew of Qu Gang's big thoughts, and immediately nodded and accompanied Wu Hao and Pang Zhengqing to the back of the car that was shot into a sieve.

The spear and the shield are complementary to each other. While the spear is getting sharper, the shield is also constantly improving its own protective performance.

Just imagine, when such a bullet hits the outside of the human body, it will explode like that, so the organs and tissues in the human body will inevitably be broken by those blasted steel shells, and even if it is broken, it will be stirred into a lake of pulp. Minimal trauma.

Seeing this, the seven of them suddenly thought of another kind of bullet, that is, the explosive bullet. To complicate matters, it is not that the warhead is hollow, but also that the cracking line is preset, so that the bullet will explode before shooting the object, and those warhead fragments will fly everywhere under the body.

Before walking back, Xiaojia was startled by the appearance of the car. One side of the car was full of bullet holes, very sparse, and the bullets flew to the other side of the car before going through some of the car's body. However, because the shape of the bullet changed before passing through the body on that side, it would roll over as a whole, so the bullet holes under the body on the other side were smaller, and all were large holes that were torn.

The steel shell burst and exploded along the preset seam into a sunflower, which looked pretty bad looking. But Wu Hao, including Pang Zhengqing, felt any good or bad outside the eyes of Wu Hao, which made the seven of them gasp.

However, with the further development of electromagnetic weapons, the protective power of the shield is being weakened little by little. "

Very complicated examples, such as the electromagnetic gun behind the target, are difficult to defend against. At present, the range of electromagnetic guns equipped by the navy can reach less than 100 kilometers, and the bullets they use are not tungsten-core armor-piercing bullets, or solid shells. Some electromagnetic gun shells will use inert ammunition, but they are extremely small. Some electromagnetic guns use that kind of solid shell.

The deformed bullet also means that it has weak lethality. In that respect, it surpasses traditional bullets.

So use it to fight the bone protective armor in the machine, UU Reading www.uukanshu.com Basically, it is not a quick way to poke tofu, just poke a hole. Therefore, in the face of such weapons, the bone protective armor in the machine will face the problem of survival, just like the weakest body armor can withstand a single shot of an anti-material sniper rifle. That gun is going to be sold at worst. You can't imagine that someone will use that gun against you. Wu Hao took a breath, and said solemnly to Luo Kai.

At present, that kind of bullet is banned by order, but it is still widely used in Laomi folk. Of course, the reason why the old Mi Maotian is allowed to use it is because although the bullet is extremely lethal, it has a strong penetrating power. It is the body armor of the Mi Police, and that is the root cause. .

Although its ballistic trajectory is relatively fixed, its speed is too slow. In addition, it is a solid steel shell, so traditional interception weapons have no effect on it. But the missile is me. The tungsten-core armor-piercing projectile of the rapid-fire gun will be cut under it, which basically constitutes damage, so it is almost impossible to be intercepted.

Seeing this, Wu Hao immediately picked up an undeformed bullet from the ground. The entire bullet hadn't been deformed, the inner steel casing was cracked, and the lead outside hadn't leaked out.

And what they see is just your individual rifle system, you don't have an anti-materiel electromagnetic gun, it uses 12.7mm bullets, and it has less power, slower fire rate, longer range, and penetrating ability weaker.

Unless that gun is directly banned, there is a law to stop it. Electromagnetic weapons are the trend. Even if there is no electromagnetic gun like yours, it is estimated that there will be no other electromagnetic guns in the next few years.

The seven people finally saw the power of that bullet that time. The bullet holes under the scrapped car were not the worst proof of its super weak penetration ability.
