Siheyuan: I eat melons while doing scientific research

Chapter 1205 Retro Equipment (4k)

Gao Zhendong naturally wanted more than anything. It was a happy thing for him to be able to let his comrades have a good meal. He felt that the material supply at this time was a bit like what his elders described in the 80s in his previous life.

It’s not that there is a severe shortage, but it’s far from being abundant either, as supplies still have to be funded by tickets.

As comrades in the Research Institute, we should be relatively better off than the general public, but protein and other things are definitely far from being fully supplied.

Gao Zhendong had already asked someone to notify Sha Zhu to set up two tables and start eating at a certain time. Even though the matter had not been discussed yet, they would eat first.

Fortunately, things went smoothly today. The comrades were all very professional and understood things quickly. Another reason was that Gao Zhendong did not have time to digest the book completely after he got it, so naturally he could not speak for long.

After dinner, Gao Zhendong saw them off and returned to the office. Then the buzzer sounded, indicating a new email. Gao Zhendong opened the email. The email was not long and he could read it all at a glance.

After taking a quick glance, Gao Zhendong slapped his thigh and said, "Great! That's great! Hahahahaha!!!"

The laughter startled the comrades at the door. They knocked on the door, stuck their heads out to take a look, and then left.

The email was sent by the Agriculture and Livestock Commission.

"...Thank you for your attention despite your busy schedule. Our comrades successfully found the special natural plants that they urgently need for scientific research in Haijiao City, Tianya Island last November...We are now successfully carrying out the next step of research..."

Gao Zhendong counted on his fingers and found that if it was November last year, it was really early. Although the research time was shortened, the most troublesome and also the most time-limited part of this work was that plants need to grow slowly, and during this period of time, there was a lot of time for research, analysis, statistics, and experiments.

Even though the research progress is not yet completely solid because the plants were obtained early, more time is needed to do basic theoretical and technical research. Maybe the results cannot be achieved in 3 years, but even if it is 4 or 5 years, it is also great.

The sooner it is promoted, the sooner the problem of food will be solved.

Thinking of this, Gao Zhendong wrote a reply letter.

"…I am so happy to hear the good news. If the relevant researchers need computer assistance in their research, our department can provide computers and related software personnel, cooperate with the relevant comrades, and customize computer-related software based on the needs of the comrades to facilitate their work…"

Computers can't help much in this matter, but at least they can play a certain role in data processing, hybridization relationships, etc.

For Gao Zhendong, it is a great honor to be able to save them even a little bit of time and energy.
-
The next morning, as soon as Gao Zhendong arrived at the office, he received a call from Professor Liu of Beijing University of Technology.

"Professor Gao, are you free to come and have a look? Don't worry, I'm not going to force you to come and have a look at some new stuff this time. You've definitely never seen this thing before." Professor Liu said happily on the phone.

Conscripting young men means that Gao Zhendong will never be forced to spend energy solving the problem again.

Gao Zhendong smiled and said, "It's not Tuesday yet, so you want to have some foreign food, right? I'll save it for Tuesday."

"By Tuesday, the day lily will be cold. This is a sample and we will open it for research soon. If you don't come and see it now, you won't know how long it will take to pack it up next time." Professor Liu knew that Gao Zhendong liked this and tried his best to tempt him.

Gao Zhendong thought about it and thought, okay, it's good to see new things more often, you can't always be so nervous: "Okay, I'll come over and take a look. Let me make it clear first, if it's not fun, I'll ask you to reimburse me for the ticket."

Gao Zhendong just made a joke and drove over.

"Don't worry, I guarantee that if you are interested, just come to the school shooting range." Professor Liu said with a smile.

When Gao Zhendong arrived at the shooting range of Beijing University of Technology, Professor Liu was already waiting there.

Gao Zhendong walked forward and asked: "What's this rare thing?"

Professor Liu mysteriously pulled away the cloth covering an object nearby and said, "This is it. I know that those of you who have served in the military like to have many tubes. This thing has many tubes."

The military representative next to him smiled and said, "Yes, it is indeed a lot."

Gao Zhendong took a closer look and started laughing. This thing really is...

Although it was he who suggested this, it was the first time he had seen the real thing, not because it was too advanced, but because it was too retro.

Now appearing in front of him was a hand-cranked Gatling machine gun!
I don't know where Professor Liu got this antique. If it's kept for a few decades, it can be put in a museum. No, it can be put in now, after all, this thing has been used since the American Civil War.

Gao Zhendong couldn't help it: "Professor Liu, where did you get this thing? Even if it was made by many countries when we were fighting, we couldn't find this thing, right?"

When we fought wars before liberation, we always used whatever we had, and our own production capacity was insufficient. It is not an exaggeration to say that it was made in many countries. Even so, this thing should not be found.

The main reason is that it is too old. In S2, Gatling was in a very awkward state and almost no one used it.

Professor Liu smiled and said, "We got this from abroad. We asked the Gauls for help. I don't know where they got it from. In fact, we only got this thing back for one purpose, to see the structure of the Gatling gun. The firing rate of this thing is almost the same as the existing machine gun with one zero added."

He jokingly called Gatlin "plus a zero", and Professor Liu was also considered a talent.

But his idea is actually not wrong. No one in China has ever made a Gatling gun. If he starts from scratch, it is hard to say how long it will take. With this, the research speed can be greatly improved.

The most coincidental thing is that when Gao Zhendong asked for the Gatling 625, he asked for an external energy source. The hand-cranked Gatling is an external energy source, which just fits in well in terms of principle. If it was an internal energy source, it’s hard to say what it would look like.

When Professor Liu and others were working on this thing, they were still admiring Gao Zhendong's considerations, which were really linked together. It not only obtained the benefits of the external energy Gatling, but also reduced the difficulty of research and development.

In fact, there is only one reason why Gao Zhendong doesn't like the internal energy Gatling gun - this thing really can't hit the target accurately, or the cost of hitting the target accurately is too high. For anti-aircraft guns, inaccuracy is the original sin.

This is not a heavy machine gun that can get by on scattering.

Gao Zhendong looked at this thing with interest. When he saw its ammunition feeder, Gao Zhendong covered his forehead. The ammunition feeder of this thing was a tall magazine.

Did the Gauls think we were making this stuff for collection, and went to great lengths to find a very retro one?
It’s no wonder that the Gaul guy who was in charge of this matter really thought so and felt quite proud of it.

It is a yes to do bad things with good intentions.

Professor Liu knew what was bothering him, and said with a smile, "It's okay. We have experience with belt-fed ammunition, so this shouldn't be a problem for us. Besides, this thing is fun to use. Come on, try it."

Now that we are here, there is no way to change the thing since it looks like this. Gao Zhendong is a bachelor anyway, so let's just beat him.

"Da... da... da... da... da..." No matter how hard he tried, this thing was still half dead. It was incomparable to the current regular machine guns. The firing rate of the exogenous Gatling gun depended entirely on the size of the external energy source.

Gao Zhendong felt like he was about to get mad, so he stopped after firing two magazines: "This thing is really not as good as rubbing it by hand, no wonder no one uses it."

However, Gao Zhendong is still very satisfied to be able to play this thing with his own hands. Don’t worry about whether it is slow or not, but it has a heavy sense of history.

Leaving the shooting position, Gao Zhendong turned around and said with a smile: "You will mainly have to deal with this thing next."

"Yes, the machine is almost ready. Although 12.7 is still being worked on, we have enough manpower."

"Well, I guess there should be no problem. By the way, what kind of bullets are you going to use?" Small-caliber weapons are different from large-caliber weapons. The decisive factor in the research is the bullet, not the cannon. All the work is carried out around the "bullet".

So Gao Zhendong asked what kind of bullet he was going to use.

Professor Liu said: "Our idea is to use the ammunition of the 25mm gun on the Army Infantry Fighting Vehicle, 25*165."

Gao Zhendong thought about it and nodded: "Well, this is a good idea. We can carry a lot more shells."

The biggest difference between the 25mm gun on the infantry fighting vehicle and the navy's double 25mm is that the shell has been shortened a lot. The navy's double 2mm gun is derived from the Russian 3M25, and the shell is really too long.

"We expect the range to be 3000 meters and are currently conducting research on the shells."

The range of the double 25 is about 2.8 kilometers. The shells have been shortened, but the range has been increased. Gao Zhendong is not worried about this. It is not difficult to achieve this goal by changing the propellant and adjusting the internal ballistics.

"Where are the ammunition?" Gao Zhendong continued to ask. Since they were already here, it wouldn't be illegal to discuss it more.

"High-explosive fragmentation bombs." Professor Liu said.

"What fuse?"

"Touch the fuse."

The radio proximity fuze has certain requirements for the caliber of the artillery shells. It is undoubtedly a bit too much to want to put it into a 25mm cannon at this time.

Gao Zhendong thought about it and shook his head.

"What? This is inappropriate?"

"Yes, it's not suitable. It would be better if it had a proximity fuze, but it is difficult to install a proximity fuze on this shell, and the cost is too high. Even if it is made smaller, almost half of the shell will have a proximity fuze, and the power will not be good enough."

"According to the ballistic performance and firing rate of the gun and the shells, the shells have a sufficient hit rate against typical ground-to-ground and anti-ship missiles. We calculated this at the beginning, so the impact fuse can also be used."

Gao Zhendong laughed: "Old Liu, Old Liu, why are you so honest?"

Professor Liu was stunned: "Ah? Honest?" He felt that he was not very honest, but he did not expect Professor Gao to defend him like this.

"Yeah, since we're already at it, why not just use armor-piercing bullets? Compared to grenades, they have a simpler structure and are easier to manufacture."

Professor Liu touched his head...it seemed to be the case.

"The main reason is that for sufficiently strong semi-armor-piercing warheads or thick-body bombs, the destructive power of high-explosive fragments is insufficient. In this case, these weapons may still hit the target by inertia and cause significant damage."

Professor Liu is not an expert on anti-ship missiles and other weapons, so he is naturally not as familiar with their structure as Gao Zhendong.

Professor Liu was stunned: "Eh... that makes sense. We are developing close-range anti-aircraft weapons. It would be best if we could completely destroy the enemy's weapons in mid-air."

"Moreover, when necessary, this gun can be laid flat to counter light armor, and the armor-piercing shells are still very useful. But don't pull down the grenades, you can mix and match them." Gao Zhendong was obsessed with laying the anti-aircraft gun flat.

It's too vicious... If they really use armor-piercing bullets, let alone light armor, even a regular tank will lose a lot of combat effectiveness if it is hit in the face by 25mm armor-piercing bullets. If it hits the buttocks or side armor, the consequences will be even more unpredictable.

Professor Liu nodded and said, "Okay, let's go back and add a steel core capped armor-piercing bullet. This is easy to do. Infantry fighting vehicles already have this kind of ammunition, so there is not much that needs to be modified."

The capped armor-piercing projectile is a two-fold variation of the ordinary armor-piercing projectile. The ordinary armor-piercing projectile is capped with a soft metal cap to reduce the probability of ricocheting and enhance the normalizing effect. The capped projectile is a hollow fairing added to the front of the armor-piercing projectile to achieve better ballistic performance.

If you put the two together with the cap first and then the wind cap, you will get a relatively balanced ordinary armor-piercing bullet.

Gao Zhendong shook his head: "Hey, Lao Liu, you'd better be honest."

Professor Liu didn't know whether to laugh or cry. Why was I so honest? "So what do you mean?"

"If we want to do it, let's do it on a larger scale, using a spin-stabilized armor-piercing projectile with a tungsten alloy core! When you have time, you can do preliminary research on the fin-stabilized armor-piercing projectile with a tungsten alloy core to further enhance the armor-piercing potential. I don't believe there is any missile that can withstand this thing!"

Gao Zhendong went completely crazy and even Professor Liu was stunned.

"Professor Gao, isn't this a bit..."

You are simply aiming for the side armor and the rear of the tank. No matter how strong the tank is, it will not feel good if it is splashed with water by 25mm tungsten alloy armor-piercing discarding sabot bullets in these two directions.

Gao Zhendong shook his head. "It's OK. The supply of tungsten alloy has increased and the price has started to go down. We can still afford it. I'm from the 17th Machine Department. I know everything about this."

To be honest, if the Americans had more tungsten, they would not load depleted uranium bombs onto armor-piercing bullets. However, it is hard to say whether this is the case or not, as the Americans have a very obvious advantage of low human rights.

Looking at Gao Zhendong at the shooting range of Beijing University of Technology, Professor Liu thought, "How come you still remember that you are from the 17th Machine Department?" How strange.

But Gao Zhendong's words gave him a big shot of confidence. If that was really the case, then why would he hesitate?
I didn't consider it before because I wanted to save money. Now the comrades from the 17th Ministry of Machine Building say that this thing is fine, so why don't we get it started right away!

"Okay, okay, I'll add a tungsten core armor-piercing bullet when I get back!" Professor Liu said excitedly, but he was still rational enough to keep the option of the capped steel core armor-piercing bullet.
