The cavity effect, Yang Mingzhi explained in a nutshell, is that when a bullet hits the enemy's body, it creates a huge cavity. The diameter of the cavity can be several times or dozens of times that of the bullet.
"Ah? You mean, the bullet hit the target and produced an explosion-like effect?" Fedorov asked in astonishment.
"What you said is not rigorous, but in terms of the result, the effect is indeed like an explosion?"
"Oh? I really want to hear your detailed explanation."
In this conference room, the elderly Fedorov was highly respected. He was listening attentively, and it was hard for others to say anything.
Yang Mingzhi also knows that the bullets used in assault rifles determine that their power is weaker than that of old-style rifles with large bolts. In order to make up for the disadvantage in kinetic energy, other aspects must be made. Making full use of the cavity effect is excellent.
s method.
As early as when he began to conceive of the production of assault rifles, Yang Mingzhi's first consideration was small-caliber bullets with a height of less than six millimeters.
Whether it is 5.56 mm or 5.45 mm, the calibers are quite close to each other, and the serious cavity caused by the bullet on the target is also very scary. However, at the beginning of the development, old fools thought that a bullet with a diameter as big as a soybean would be enough for just one bullet.
Being able to blow half of the enemy's head off is definitely an unrealistic delusion!
When it comes to matters related to national defense, the Russians dare not be too radical. Moreover, the world's major powers still hold the full-power eight-millimeter rifle bullets, so they cannot afford to suddenly develop small-caliber bullets.
Therefore, Yang Mingzhi did not step too far and sprain his hip. Simonov's bullets already met his needs very well. Besides, although the cavity effect of this bullet is not as good as the "small poison bullet" of the AK74, its cavity effect is already very good.
considerable.
Yang Mingzhi cleared his throat, and everyone began to explain.
"Now, the rifle ammunition equipped by the world's major powers are full-power rifle ammunition, and its size is either 7.92 mm or 7.62 mm. That is, 8 mm, or 0.3 inches. This type of bullet has enough bullet weight and can store more
After the bullet hits the enemy's body, due to the overall long warhead, it immediately begins to tilt and roll, smashing the body tissues in the path into meat paste, causing the enemy's internal organs to rupture and bleed to death. The enemy who was shot basically looks like this
You all know how to die.
Due to the crazy rotation of bullets during flight, the first priority is to use the gyroscopic effect to stabilize the trajectory and avoid the headless flies of the smoothbore gun.
However, one thing you may have overlooked is that bullet rotation can also provide another type of lethality, which is the so-called cavity effect."
"Wait!" Simonov heard this and suddenly interrupted Yang Mingzhi: "You mentioned this theory. In fact, I also considered this aspect when I was doing research."
"Really? Ah... It seems that I am not the first person to discover such a situation." Yang Mingzhi shrugged and continued to ask: "So, how much do you know?"
"This...exploration in this area takes time, but unfortunately my time is very limited."
"Is that so? It seems that I should be the first to conduct research in the entire alliance."
What Yang Mingzhi said was not a boast. Many times, the results of historical events are formed through a series of coincidences.
It was in that dimension that the Soviet Union discovered that the U.S. military's cutting-edge assault rifles had achieved a large number of incredible kills in the Vietnam War. The Soviet Union obtained a large amount of intelligence and realized that the U.S. military used small-caliber bullets to inflict huge wounds. The authorities immediately benefited from Kalashni's rise.
Kove led the research. It is conceivable that if Kalashnikov did not have the research and development capabilities in this area, although the Soviet small-caliber assault rifle could still be born, its birthday would be delayed for a long time.
This is how the AK74 was born. It can be said that it is the best assault rifle developed by the Soviet Union in its 71-year history.
Of course, perhaps the performance of the an94 developed by the Abagan Institute is more superior, and this is indeed the case, but excellence is based on high costs. This is a huge economic burden that the new Russian Federation cannot bear!
Now, in Moscow in 1942, Yang Mingzhi demonstrated an assault rifle to the Soviet Union's main small arms research experts, and solemnly explained the "killing principle" of another bullet.
"The bullet developed by Comrade Simonov has a much lighter warhead than traditional rifle bullets, so the moment it hits the target, it stores much less energy. It seems that it does not store enough energy? No! This is a misunderstanding!
Its stored energy is enough to break the bones under the muscles.
And the moment it hits the flesh, the bullet itself is still spinning at a very fast speed.
Therefore, its energy storage is relatively insufficient, and the inertia force given by the bullet's bullet weight is also limited. It often cannot penetrate the enemy's body. What does this mean? The kinetic energy of the bullet will be completely absorbed by the enemy's body, and the body in the hit area
The organization will bear all damages.
The bullet is not slender enough, and its degree of deflection and roll is relatively limited. Its crazy rotation and forward speed must be transmitted to the body tissues on both sides of the trajectory.
Those muscles gained strength, as if they were thrown out by a force, moving along the direction of the bullet's rotation, instantly creating a chamber in the body!"
Having said this, Yang Mingzhi noticed the refreshing looks in everyone's eyes, and Fedorov's aging eyes shone again.
"Is this the explanation for the cavity effect? No! It's not comprehensive!" Yang Mingzhi continued to explain: "The bullet that hit the enemy's body did not explode, but the muscles near the trajectory gained the power to move, and the muscles and other bodies
The tissue leaves its original position, creating an extremely short vacuum, and a large amount of air enters the chamber through the entrance of the bullet in an instant. The entering gas expands passively, causing another damage to the body tissue. Our internal organs are extremely fragile.
Yes, they cannot withstand such force at all. Although the cavity effect can only exist for maybe ten milliseconds, the internal organs have been completely shattered. No doctor can save such a wounded person.
However, the effect of this damage decreases with distance. If the enemy is shot at close range, the instant cavity caused by the bullet can break through a large area of the enemy's skin, causing a huge blood hole. It may hit a target 800 meters away.
It is quite similar to the damage caused by Tokarev pistol bullets."
Yang Mingzhi gave some explanations, and he believed that he had explained the problem very thoroughly.
He was actually very dissatisfied with Beria's operation in the early morning, not only because the Ministry of Internal Affairs used a prototype gun to shoot without authorization, but also because the first professionally built assault rifle in human history completed the first shooting in a prison.
This is not a good sign! It is a conventional light weapon used by soldiers. When used for the first time, it actually became a tool of execution. How unbecoming?!
Beria is so powerful that people have to bow their heads under the roof!
Now that Beria personally produced a report and claimed that he himself was the "executioner," Beria still remained silent and put on a serious face. His eyes trembled inadvertently, which fully demonstrated his innermost feelings.
of fluctuations.
Yang Mingzhi felt that since early morning, Beria himself had already approved his new gun.
When I think about it, isn't it a good thing that the Ministry of Internal Affairs uses prototype guns without authorization?
Everyone, including Fedorov, became strongly interested in the "cavity effect" at this moment.
The documents Beria produced seemed to prove the effect of the "cavity effect", and the effect was outstanding!
As long as a bullet has a stable ballistic trajectory, sufficient muzzle velocity, sufficient kinetic energy to focus on the target, and can focus on a live target, it is an excellent bullet, and the firearm that fires it is also a good gun.
In this time and space, the research on bullets and even firearms by major countries is limited.
In most countries, the standard infantry equipment is bolt-action rifles. Compared with the booming artillery and machine guns, infantry light weapons and equipment are obviously not keeping up with the advancement of the times.
The exquisite mechanical designs inside the assault rifles and squad light machine guns developed by Yang Mingzhi made experts shine.
The most exciting person here is Simonov.
Because, Yang Mingzhi claimed in public that the aerodynamic principle of the assault rifle was fully based on the svt40.
Regardless of the pneumatic principle of firearms or ammunition, both are research results of the Simonov Institute.
Of course, Yang Mingzhi is definitely not plagiarizing. The key to the firearm is the bolt. It uses only a few parts, but every part purchased has undergone complex processing.
The mechanical structure composed of parts allows the firearm to shoot fully automatically and semi-automatically, as well as the firearm safety switch.
They all rely on a wrench to control the internal mechanical structure, which is simple and has more functions.
Can svt40 do it?
Simonov simply asked: "Comrade Berekov, which university did you learn this mechanical knowledge?"
"I learned it from a watchmaker. You know, all watchmakers are excellent mechanics. As far as I know, American Browning and even German Maxim, they are all excellent watchmakers."
"It seems that you are not an academic." Simonov did not believe what Yang Mingzhi said. This man from China is simply a genius in developing weapons.
The best firearms research and development experts from the Soviet Union are all standing here, but compared to their conceptual attainments, it is obviously this Chinese man-made attainment that is deeper!
The situation becomes a little tricky.
The industry experts who were invited here inevitably have great pride in their own industry. Although this Belekov has made some wonderful ordnance inventions, can he still create such novel guns?
What's good now, should I be like a teacher, giving key guidance to Berekov, or should I be educated by Berekov?
The result is obviously the latter.
Simonov was shocked and Berekov succeeded in studying his research more thoroughly than himself.
Deggarev was shocked that the drum system developed by Berekov far surpassed his own.
Fedorov is indeed a leader in the industry. He keenly realized that the direction of firearms research and development should be significantly adjusted.
So, the two new guns that Yang Mingzhi put on the table have yet to be concluded.
Until now, whether Simonov or Deggarev, or others, everyone is waiting for the old Fedorov to give the young Berekov a pertinent definition.
The scene was quiet for a while.
"Comrade Berekov," Fedorov said in an old voice.
"Please speak."
"I am a rigorous person. Although Comrade Comrade NKVD has provided a report that seems to support the cavity effect you proposed. For the time being, I cannot be sure whether it really has a different killing effect.
Now I can confirm one thing, the structure of your firearm can be completely modified to fire the full-power rifle ammunition with the largest amount of equipment in our country."
"Ah!" Yang Mingzhi didn't know what to say for a moment.
"What? Do you have any objections? I know that the firearms you develop are made for intermediate-power bullets. But I looked at the drawings you provided and found that the materials used in the barrel and chamber can fully withstand the pressure of full-power rifle bullets.
!
Because the factory that supplies these key materials is the one that produces Mosin Nagant.
As long as we modify it, your assault rifle will become a conventional automatic rifle, even better than the existing light machine guns of our army.
I came to a very clear conclusion.
The structure of your firearm is refreshing, and it has huge room for transformation. No matter what the results of tomorrow's shooting range experiment are, I think the comrades standing in this office should fully study your drawings and sample guns."
Fedorov's words were very subtle, and Yang Mingzhi could tell that this leader in Soviet small arms research and development had fully recognized his firearms.
Reading between the lines, he recognized at a glance that the bolt mechanism of the assault rifle was the most exciting design of the entire firearm.
Fedorov also praised the design of the muzzle suppressor and the left and right folding of the butt, which are actually the icing on the cake.
The bolt mechanism and the characteristic drum structure are fully integrated, and the barrel used has fifty years of experience.
When they are fused together and the work is entrusted to anyone present, isn't a light machine gun far superior to the DP28 born?
Of course, Berekov has already produced a finished product. Tomorrow, the leader will personally participate in the shooting range experiment, where the new light machine gun and the DP28 will compete on the same stage. It will be clear who is better.
Yang Mingzhi actually heard another voice from Fedorov's attitude.
It is very possible that this master has never liked Deggarev's works. That's why he arbitrarily believed that a replacement for dp28 had appeared before the shooting range experiment. Obviously to consider Deggarev's feelings, Feder
Love quickly spoke more tactfully.
So Deggarev was displeased?
Quite the contrary! There are a large number of "engineering blueprints" for firearms manufacturing lying on the table. The Soviet Union did not have individual patents, and the intellectual property rights on the drawings were all the property of the state!
Although various design bureaus are essentially competitive, their research results are institutionally transparent to each other.
Design bureaus have no right to have reservations about their peers, and any reservation is considered bourgeois behavior.
"Comrade Berekov, I now clearly tell you my attitude. I recognize your research and development results. I sincerely wish your firearms the greatest success in tomorrow's shooting range experiment."
A smile appeared on Fedorov's old face, and his beard stopped trembling.
"Thank you! On behalf of everyone at the Pripyat Arms Design Bureau, thank you for your praise." After saying that, Yang Mingzhi bowed deeply to show his respect.
"You don't have to be modest. Now the country needs your research and development results. So, next..." Fedorov whispered to the table, "According to regulations, these design drawings you provided will be shared with other comrades now. What do you think?"
Although the Soviet Union did not care about intellectual property rights, Yang Mingzhi came from another time and space after all, and it was inevitable that he felt a little uncomfortable.
Standing in this room were Beria and Uskinov, who was responsible for the development and production of weapons across the alliance. Yang Mingzhi showed his pot belly and enthusiasm without hesitation.
Besides, this is not a church where apprentices starve their masters to death. Colleagues have learned new ideas. As long as the Soviet Union still exists, there will be no conflict between peers. They are in a friendly and cooperative relationship, and technology should be shared.
"I brought the drawings just to share them with you. You can take them as you like."
Of course, for the experts present, everyone does not feel comfortable holding it.
Belekov's designs were more sophisticated than his own. Taking away the drawings, he didn't have to pay any tuition fees, and he didn't even have to give a bottle of vodka as a token of thanks.
"This...we will take your drawings and start research immediately!" Deggarev said, "Thank you for your support."
"Haha! Dear Comrade Deggarev, you'd better start researching it immediately."
"oh?"
"Haha, I have to offend you. Loading your light machine gun magazine is a disaster. I suggest you make adjustments immediately and use my drum design. In this way, your machine gun will have several times more ammunition than it does now.
Practicality.”
"I'm thinking about this! Haha, maybe my new gun has better performance than the new light machine gun you put on the table!"
As if this was a challenge, Yang Mingzhi just shrugged: "I accept your challenge."
