Military Technology

The gun was smoking, but it wasn't really a big deal. When the gun fires continuously, the temperature inside the gun chamber will soar rapidly, even reaching several hundred degrees, and the entire barrel may burn red.

The handguard on the gun will also ignite due to the 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 normal. Under normal circumstances, you need to stop shooting at this time to allow the barrel to cool down naturally, or to replace the barrel.

In fact, many machine guns are equipped with a second barrel to facilitate replacement and cooling. In order to avoid this situation, people conducted research and exploration on barrel shooting cooling, and finally developed two technologies, which are air cooling and water cooling technology.

To put it simply, air cooling means using a heavy barrel and adding radiators on the barrel to dissipate heat. The more famous ones in this regard are the Type 92 heavy machine gun equipped by the Little Devils during the Anti-Japanese War, also known as "Bright Sword" "The heavy machine gun that Li Yunlong was reluctant to throw away when he broke out and retreated was a representative example of air-cooling.

In addition, there are Germany's G34 and G42 general-purpose machine guns during World War II, as well as Lao Mi's M2 heavy machine gun, which are all air-cooled and heavy-barreled machine guns.

The water-cooled machine gun is earlier. The most typical and most representative one is the Maxim heavy machine gun that you often see in movies and TV series. It has a very thick cylinder on the barrel. The inside of this cylinder It will be filled with water, which will have a cooling effect on the barrel.

During normal marches, in order to add weight and facilitate portability, there was no water outside the cylinder. When it comes to actual combat, water needs to be filled outside. Therefore, there will be no soldier outside the heavy machine gun squad carrying a bucket of water to prepare.

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

Wu Hao nodded when he heard Luo Kai's words. Then, before he removed the ammunition box and inspected the gun, he looked at the scrapped car nearby and said, "Come on, let's go over and take a look."

The seats outside the car were also sieved by bullets and fell apart. Not only that, even the wheel hub of the car was punctured, and it was the wheel hub that could stop the bullet who knew who was spreading the rumors.

Luo Kai nodded slightly when he heard this, and then shook his head.

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

Speaking of that, Luo Kai laughed: "Yes, it does matter. When it comes to the skeleton protective armor in your machine, bullets and electromagnetic guns are still useless.

That is mainly because the muzzle velocity of the electromagnetic gun is too slow. It is difficult for traditional artillery shells to withstand such speed and force, and it is difficult to detonate with delay, so it is wise to use solid shells.

Of course Luo Kai knew Qu Gang's big thoughts, and immediately nodded and accompanied Wu Hao and Pang Zhengqing to the car behind the shot.

The spear and the shield complement each other. While the spear becomes sharper, the shield also continuously improves its protective performance.

Just imagine, when such a bullet hits the outside of the human body, it will explode like this. The organs and tissues in the human body will inevitably be severed by the exploded steel shells. Even if they are broken, they will be turned into a lake of slurry. Minimal trauma.

Seeing this, the seven people were reminded of another kind of bullet, that is, the explosive bullet. To put it more complicated, not only is the warhead hollow, but it also has a preset cracking line, so that the bullet will explode completely before hitting the object, and the warhead fragments will fly everywhere under the body.

Before retreating, Xiaojia was startled by the appearance of the car. One side of the car was full of bullet holes, which were very sparse. The bullets flew to the other side of the car before penetrating some parts of the car. However, because the shape of the bullet changes before passing through the body on that side, it will roll over completely. Therefore, the bullet holes under the body on the other side are smaller, and they are all large torn holes.

The steel shell exploded along the preset seams and exploded into a sunflower, which looked quite bad. However, Wu Hao and Pang Zhengqing could not see anything good or bad, which made the seven of them take a breath.

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

Very complex examples, such as the electromagnetic gun behind the target, are difficult to defend. The electromagnetic guns currently equipped by the Navy can have a range of less than 100 kilometers. The weapons they use are either tungsten core armor-piercing projectiles or solid artillery shells. Some electromagnetic gun shells use inert ammunition, but at present they are extremely small. Some electromagnetic guns use solid shells.

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

So using it to punch the skeleton protective armor in the machine is basically not just poking a hole in the tofu with a tachyon. Therefore, facing such a weapon, the skeleton protective armor in the machine will face survival problems, just like the weakest body armor is still worth a shot from an anti-equipment sniper rifle. The worst thing about that gun is that it has to be sold. You can't imagine others holding that kind of gun to deal with you. Wu Hao took a breath, and then said solemnly to Luo Kai.

At present, this kind of bullet is banned by order, but it is still widely used among the people in Laomi. Of course, the reason why it was allowed to be used by Lao Mi Mao Tian Xiao Shi Wei is because although the bullet has a very small lethality, it has strong penetrating power and can pass through the bulletproof vest of Mi Police. That is the fundamental reason. .

Although its trajectory is relatively fixed, its speed is too slow. In addition, it is a solid steel cannonball, so traditional interception weapons have no effect on it. The missile hit me, and the tungsten core armor-piercing projectile of the rapid-fire cannon would be scratched under it, which basically caused damage, so it was almost impossible to intercept it.

Upon seeing this, Wu Hao immediately picked up a bullet that had not yet deformed from the ground. The entire bullet had not yet deformed, the inner steel shell had cracked, and the lead from the outside had not leaked out.

And what they see are just your individual rifle systems. You don’t have an anti-material electromagnetic gun yet. It uses 12.7 mm bullets, and has smaller power, slower rate of fire, longer range, and poor penetrating ability. weaker.

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

That time, the seven people finally saw the power of that bullet. The bullet holes under the scrapped car were not the worst proof of its ultra-weak penetrating ability.
