The Life of a Gangster That Started In a Gun Shop

The so-called stop effect, in fact, many people have always had a misunderstanding.

That is to understand it literally, the warhead hits the target, the faster it stops, the stronger the stopping effect!

This even leads to some fallacies that the stronger the penetration, the worse the stopping effect.

In fact, the English translation of stopping action is: stoppingpower, if it is a literal translation, it should be translated as shooting power. Shooting power, this is easier to understand, it is commonly known as bullet power!

In a standard Mandarin explanation, the real meaning of stoppage refers to the effect of quickly incapacitating the person who has been shot.

The stronger this effect, the greater the power of the bullet!

As for the stop effect, in fact, there has been no clear standard definition for over a hundred years. There is not even a basic theory, the only consensus reached is that stopping the effect does not mean lethal ability!

Ye Qing doesn't know if this is for the humanitarianism of Nashilaozi. Anyway, the standard has become lower, which is a good thing for Ye Qing.

This means that you can kill a little less brain cells...

No matter how the standard changes, mentioning the stop effect will inevitably include mentioning the cavity effect. The so-called cavity effect is that when the warhead is told to impact the target body, it will open a channel-like wound and spread to the surrounding tissue.

The cavity is generally divided into two parts, the transient cavity and the permanent cavity.

These two concepts are also easy to understand. The so-called instantaneous cavity refers to the post-bullet cavity that appears at the moment when the warhead enters the human body, which is when the cavity is most inflated.

Its diameter can usually reach 20 to 30 times the diameter of the warhead. The permanent cavity is a fixed wound formed by shrinking and expanding the surrounding tissue several times on the basis of the transient cavity, and finally gradually shrinking.

The key to the ongoing debate about the stopping effect is also here. To enhance the stopping effect, should it be more effective to increase the transient cavity or increase the size of the permanent cavity?

No, to be precise, is it useful to increase the transient cavity?

Ye Qing frowned and seemed to have a headache.

Because there is a real case in history, an FBI agent was shot in the neck by a .223 rifle. But the bullet did not hit the cervical spine, and the detective was paralyzed for several hours.

This is undoubtedly the credit of the instantaneous cavity!

Although the agent was treated without serious injury after the incident, this shows that increasing the size of the instantaneous cavity did not improve the lethality.

According to the standard of incapacitating the shot, the instantaneous cavity size can be increased, and the standard is completely met.

After tangled for a while, Ye Qing decided to follow the mainstream and find a way to increase the size of the permanent cavity, instead of doing those bells and whistles.

There are generally two ways to increase the size of a permanent cavity.

One is to use the hollow-pointed bullet, which is mainly used for 9mm or .45 low-speed pistol bullets. The feature is that there is a hole at the top of the warhead, so that when flying and hitting the target, the warhead will rapidly expand and deform, simply and rudely prop up a larger wound channel;

The second is commonly used by small-caliber rifle bullets by increasing the speed and lap speed of the warhead rolling in the air, allowing the bullet to stir up a larger wound channel in the target body faster.

In theory, you have gunpowder with better performance, and you can directly use the second method.

The initial velocity of the bullet is faster and the instantaneous chamber pressure is higher, which can completely increase the rotation speed and the number of tumbling turns of the warhead in flight. But in this way, the focus of the research is not on the bullet itself, but on adjusting the rifling accordingly to pursue a greater effect.

Of course, even if you don't do it, just go fishing and paddling. The power can also be improved by directly changing gunpowder, which has been proved by XCMG's previous tests.

But if you want to pursue excellence, you can only think of a solution on the first type, that is, the hollow tip.

"How big should this hole be?"

Ye Qing rubbed the aching brain. One thing to say, the job of a designer is really not something ordinary people can do.

It seems that the hollow point bullet is just a hole in the top of the bullet, but how big should the hole be? How deep do you drive? How much influence does it have on the trajectory of the bullet's flight?

Since I developed a standard rifle bullet, it is conservatively estimated that the flight distance of the bullet is also about 200 meters, and even further conditions have to be prepared.

In this way, if the warhead case is not strong enough, it will not fly halfway. The air resistance directly expands the warhead, thus wasting a lot of kinetic energy and reducing the power?

If the strength of the bullet shell is too high, and it will not expand when it is hit into the human body... Then it is even more unreasonable, and it is a joke to make an empty-pointed bullet...

Faced with this series of questions, Ye Qing secretly rejoices that there are so many people now.

This is just one of the studies, and it is complicated to this extent. I really don't dare to think about those more sophisticated fighter planes...

There is no teamwork, only individuals. Even if you exhaust yourself to death, you may not be able to fix things.

After assigning the experimental task of the hollow-point bomb to the assistant researchers, Ye Qing began to try it for the first time.

According to your own task, you only need to make one of them, experiment with performance, and finally summarize.

This made me a lot easier.

Seeing that the small arms laboratory started to be in full swing but started to be busy in an orderly manner, the other experts who were watching also left with interest...

I can only understand a rough idea by looking at it, and it is useless to stay here.

With the efforts of everyone performing their duties, the research and development progress is advancing very quickly. After all, strictly speaking, Ye Qing's approach was very rude.

Different warhead types are tested separately.

Pick out the best-performing combination in each group~www.wuxiaspot.com~ and then carry out the mixed test. Until you find the best mix!

This can no longer be regarded as pure research and development. Compared with research and development, it is more like reverse push. In other words, the derivative use of new gunpowder and new materials.

But so what? Bullet shooting itself is structural design, they are physical engineers, not chemical researchers... As long as the final result is good, it doesn't matter how it came out.

In just half a month, the new bullet has come out.

The warhead part still uses a full jacket warhead, and the aspect ratio of the bullet is reduced. The length of the warhead has also been adjusted to a certain extent, and it has been reduced to a certain extent on the basis of the long-headed jacket.

The caliber followed the caliber of 5.56 and the caliber of 5.8mm, and also tested one separately. Presumably, just a little longer the length of the warhead and chamber.

Compared with the original bullet, the new bullet is lighter in weight and smaller in size.

Even if all the calibers match the mainstream weapons of both sides, it will take a long time to really use it on a large scale...
