After listening to Bai Yi's words, Chen Yaoyang was excited for a while, but then dimmed in the blink of an eye, because he suddenly thought of a question, so he immediately asked: "The lethality of the little devil's 6.5mm pointed rifle bullet is no problem, but the problem is

This kind of lethality is only at short range, basically within 200 meters. Beyond this distance, its power is no different from that of a round-nosed bullet. It is precisely because of this that when we counterattack in Myanmar, we will suppress the little Japanese."

Chen Yaoyang was a personal participant in the Burma counterattack, and the Japanese army he faced was an elite division, so he still had a say in the actual use of ammunition. As he said, the Japanese army's 6.5mm pointed bullets were certainly lethal.

It is large, but its actual range of action is not large. Its power will be greatly weakened beyond a certain distance.

Bai Yi naturally knew this, so he smiled, turned the pen in his hand to the bottom of the 6.5mm tip bullet sketch, and then lightly clicked: "This is where the problem you mentioned lies!"

Chen Yaoyang was stunned when he heard this, and immediately looked at the sketch that Bai Yi pointed to. He frowned for a long time and couldn't see the problem, so he shook his head in confusion, and then looked at Bai Yi in confusion: "The bullet's warhead is not right."

Is this all the case? What’s the problem?”

"Are you thinking about it?" Bai Yi did not answer directly, but asked meaningfully: "Are all warheads really shaped like this?"

"This..." When asked by Bai Yi, Chen Yaoyang was startled. He immediately realized it, slapped his thigh and shouted: "Yeah, why didn't I remember that machine gun bullets? Machine gun bullets are fired from rifles."

Is it an improvement? Yes, the bottom of the warhead of the machine gun bullet is indeed different, it is a... similar to a ship-shaped structure."

"Is that like this?" While Chen Yaoyang was speaking, Bai Yi had already started drawing on the paper with the pen in his hand. When Chen Yaoyang realized it, next to the sketch of a 6.5mm pointed rifle bullet, a bullet with a shape different from

When Chen Yaoyang saw the sketch of the warhead of a traditional rifle bullet, he nodded repeatedly: "Yes, yes, that's it, the warhead of the 7.92mm machine gun bullet of the Min-24 heavy machine gun."

The Min-24 heavy machine gun that Chen Yaoyang mentioned is a Chinese imitation of the German MG-08 Maxim heavy machine gun. Because it was produced in 1935, that is, the 24th year of the Republic of China, it was named the Min-24 heavy machine gun. The characteristics of this firearm

Although the model is not as good as the MG-34 general-purpose machine gun equipped by Germany at the same time.

Compared with the new heavy machine guns of other countries, they are slightly older, but the 7.92mm machine gun bullets they used were one of the few new types of aerodynamically optimized bullets in the world at that time. Because of this, in the subsequent

During the Anti-Japanese War, the Min-24 heavy machine gun was often able to suppress the Japanese Type 92 heavy machine gun.

Chen Yaoyang looked at the bottom of the boat with the 7.92mm machine gun bullet, and then at the 6.5mm pointed bullet at the ordinary tail. He frowned thoughtfully, then looked up at Bai Yi and asked unconfidently: "Is it possible?

The root joint is at the stern of this ship?"

"That's right, the root lies in the tail of this ship." Before Chen Yaoyang finished speaking, Bai Yi nodded firmly: "Don't look at it as a simple tail treatment, but the aerodynamic principles contained in it are not at all

It’s not simple either…”

As he spoke, Bai Yi used the pen in his hand to draw two simple vortex trends on the two bullets. He turned the notebook sideways on his chest, pointed at the two bullet fluid sketches with the pen and continued: "General bullets."

When advancing at high speed in the atmosphere, its tip can quickly and effectively 'push away' the air. However, when the bullet pushes away from the atmosphere, a small vacuum will be formed behind the warhead, and the atmosphere will compensate and merge with normal pressure.

There is always a vacuum area directly behind the advancing bullet. Since the air in front of the bullet is pushed away, the atmosphere will be affected by the vacuum during the backfilling process and fill the vacuum first. In other words, the air chases this area.

The vacuum is also filled by inhalation.

Therefore, the air will continue to present a vortex structure. When passing through the atmosphere in such a shape, the atmosphere behind the object will form a 'pull', because the air vortex will also interfere with the object itself, especially projectiles that use inertia as kinetic energy.

Its kinetic energy decreases most efficiently, especially for most flat-type bullets. The lack of long-range lethality is related to this. On the other hand, 7.92mm machine gun bullets..."

Before he finished speaking, Bai Yi's pen pointed to another completely different fluid sketch, and then said: "Because the diameter of the tail end of the warhead is smaller than the diameter, the vacuum space behind the warhead also shrinks accordingly, which means that the atmosphere follows the shape of the warhead.

merge instead of being pushed away and merged later,

There is almost no 'pull' interference when the warhead passes through the atmosphere, so naturally there will be no eddy currents to interfere with the warhead. Because of this, the warhead at the bottom of this type of ship is like a hot knife cutting butter when it passes through the atmosphere, cutting the air in the front section

Cut it open instead of pushing it away with brute force!"

"This... I didn't expect that just a small shape change would contain such a complicated principle." After listening to Bai Yi's explanation, Chen Yaoyang's eyes were a little straightened. As he said, he never expected that the small shape change would contain such complex principles.

The aerodynamic knowledge contained in a small bullet slug is so profound.

So much so that even he, a top student who graduated from Southwest University, sounded a little confused. He couldn't help it. Chen Yaoyang's major was mechanics, not aircraft design. It was normal for him not to have access to profound aerodynamics knowledge. However, Chen Yaoyang

If you don’t think so, since there are shortcomings, you must make up for them. Whether it is aerodynamics or fluid mechanics, as long as you can use it in the future, you must learn and understand it. Otherwise, how can we talk about serving the country with technology?

So Chen Yaoyang calmed down, and when he raised his eyes again, his eyes were even hotter than before. When Bai Yi looked at it, his heart couldn't help but skip a beat, but before he could speak, Chen Yaoyang said first: "Chief Bai, don't say anything.

, today I finally know why you were always developing

Interest in the new intermediate-power bullets has waned. I am indeed too ambitious and overconfident. I don’t even understand aerodynamics. How can I develop high-performance bullets? Chief Bai, if you don’t think I am a person

Please, please teach me aerodynamics from today on!"

As soon as he heard this, Bai Yi was immediately confused. He originally wanted to solve the problem, so he explained the principles of bullets so thoroughly. It would be best if Chen Yaoyang could understand it and just follow the path he paved.

It's a long way to go to complete China's own intermediate powerful bomb.

If you don’t understand, it doesn’t matter. When you get into trouble, go back and recharge yourself. Anyway, Bai Yi’s ears can be considered clean, but Bai Yi forgot to take into account Chen Yaoyang’s tenacity.

You must know that when you first met Chen Yaoyang, this guy was not even afraid of the dozens of loaded firearms around him in order to understand the unknown technology. Why should he care about retreating from difficulties?

Fortunately, one problem has not been solved yet, and a bigger one has come. So Bai Yi immediately shook his head and refused: "I don't know anything about aerodynamics. This thing was also learned by a man when he fought with the Soviet army in Germany.

From what the captured German experts said, we only know so much, and there really will be nothing more.”

"It's enough to listen to German experts say this. What's more, I believe that when Chief Bai followed the Soviet army into the hinterland of Germany, he met more than one German expert. As long as those people can tell you one or two cutting-edge principles.

, it will be enough for us to enjoy for a lifetime!”

Chen Yaoyang's words can be described as righteous, but the sly look in his eyes revealed his true thoughts. Although Chen Yaoyang is obsessed with various technologies and is a bit innocent and cute, his personality

But he is not stupid, on the contrary, he is very smart.

Since I got to know Bai Yi, whether it is the use of simple objects to control artillery for precise shooting, or the in-depth understanding of Soviet artillery, or the use of Misner-Sardin explosion effect on the road to defeat the gangsters, Bai Yi has demonstrated

His technical ability has long made Chen Yaoyang suspect Bai Yi's true identity.

Although Bai Yi kept saying that he accidentally learned it from captured German officers and experts when he was fighting with the Soviet army, Chen Yaoyang knew that with just one or two words from an expert that made no sense, he could

Explain obscure theories in simple terms?

After all, Chen Yaoyang is also a top student who graduated from Southwest Associated University. Although he is not as valuable as the current returnees, he also understands the complexity and difficulty of understanding the theory. Therefore, while he admires Bai Yi, he is also very curious.

, I wonder how he, an ordinary Soviet soldier, knows so much?

It's just that he is not sure yet, so there is no transitional explanation. It was not until today that Bai Yi explained the principles of bullet aerodynamics in an easy-to-understand manner. Chen Yaoyang was convinced that his suspicion was correct. You must know things like aerodynamics.

The current most cutting-edge fields are not something that ordinary people can master. Because of this, Chen Yaoyang no longer reserves his attitude and expresses it in an extremely obscure way.

Who is Bai Yi? He was a human spirit in his previous life, and the body he inherited in this life is not a good one. When the two are combined, he almost becomes a monster. He still can't understand Chen Yaoyang's words. To be honest, he is from Southwest China.

Top student of United University, intellectual

Business is absolutely online, and he comes up with theories at every turn. From the perspective of his previous life, he didn't think anything of it, but from the perspective of today's people, all of them are rare cutting-edge technologies. If one or two are okay,

It would be strange if there were too many people to suspect.
