Chapter 252 Self-reliance (first update)
Li Dali and others went on a business trip to the south. As for Liu Hai going to visit the production of gun barrels, the report has been submitted, but there is no result yet.

Liu Hai tinkered with some materials by himself in the maintenance department, mainly tungsten alloy materials. Later tungsten alloy armor-piercing bullets and tungsten alloy bullets were all good things.

We have tungsten ourselves, but most of it has been exported. Liu Hai has a lot of things in his mind.

The tank has external explosive armor, a self-tightening gun barrel, chrome-plated gun barrels, armor-piercing shells, etc. Then I felt that the horsepower of the 59 was a bit small and wanted to change the engine. Then I felt that the armor was a little bit inferior and wanted to upgrade it. Armor...ugh.

Then another vertical and downward stabilization... It feels like you can build a new tank.

Of course, the bangs will not be taken out all at once. In a few years, I will tinker with these things myself. The current civilian products are basically enough to last for many years, and there is no great need for subsequent upgrades. After all, our country is large. It will take many years for current civilian cars to become popular.

Without visiting the barrel production, there was no way to take out the barrel, so Liu Hai tinkered with the RPG first.

In fact, there are many versions of RPG. Unless the geographical environment is complex, using RPG to fight tanks on the plains is completely filled by people.

In this era, the only thing that can fight against tanks is tanks.

Today's helicopters are not as awesome as later armed helicopters. The first generation of true armed helicopters was in 65. Before 65, helicopters carrying machine guns and rockets could be called armed helicopters, but after 65 they were not called armed helicopters. .

Sun Aiguo feels happy now, but he is also worried. The support from brother units is a favor and must be repaid, so the task needs to be completed. It is best to exceed the limit so as to provide more support to brother units.

Materials come first, so when it comes to materials for Liu Hai, whether it’s guns or rockets, there must be materials that require compounding.

There is nothing wrong with materials science, which means constant experimentation and continuous recording of data, which is a bit boring to talk about.

------------------

Li Dali and others arrived in Guangzhou, and then took a boat to Hong Kong Island at night. They could not come in openly. After they arrived by boat, they were seasick and vomited. The last time they came here, they just went to Guangzhou, but there was no Take a speedboat, a fast speedboat.

After arriving on Hong Kong Island, there were also people from the mainland here, and they announced discipline to Li Dali and others, that is, they were not allowed to go out and walk around.

Li Dali and others arrived in the middle of the night. They rested for a while. Seeing the bright lights in the factory, they felt a little strange. They were still working in the middle of the night?In the Mainland, overtime work is only extended to nine o'clock, and ten o'clock is the most.

The next day, a group of people entered the factory and found that it was completely different from the mainland. This was a real assembly line.

The first is the rice cooker production line. Parts are placed next to each worker. The conveyor belt moves at a certain speed. These workers install each part. A conveyor belt is a production line.

After the conveyor belt ends, there is a brand new rice cooker, which is labeled, certified, and then packaged.

The same goes for everything else, the motorcycle assembly shop is the same, but the assembly line is longer.

Moreover, there are two shifts here, the machines are running non-stop, and you can hear the managers shouting at the workers loudly.

Li Dali and others came here to solve production technology problems. Zhongxing brand cars are also assembled here. Li Dali and others started to go off the production line to solve the problems.

Most of them came from the mainland. Li Dali and others soon found out and started chatting. Li Dali and others had stayed in Guangzhou.

At first, a few people thought these workers were so desperate, but after hearing how much others paid for one job and how many jobs could be done in one shift, they became silent.

It subverted the understanding of Li Dali and others, and caused a great psychological impact on several people, especially the salary gap between these people, and those who did not do well had to have their money deducted...

--------------

Bangs also has a big head here. No matter what he is doing, it involves a bunch of things. For example, getting a tungsten alloy bullet. If the caliber is small, it will be useless. If the caliber is large, there will be no gun?
If you want to make a gun, it involves barrel parts, precision optics, etc...

The same goes for RPGs, which also require optical aiming, and then the entire thing must be made of alloy materials to increase strength and reduce weight, as well as explosives...

So no matter what you do, it is a systematic project, and Liu Hai can't be anxious even if he wants to.

Liu Hai struggled for a while and decided to make a 12.7mm heavy-duty sniper rifle. Although it was difficult to make, it did not require large-scale equipment.

Originally, Liu Hai planned to build a smaller sniper rifle, but now that our infantry ranks first, the small caliber is of little use. We built a heavy-duty sniper rifle, which can be used as support firepower and equipped with 12.7 mm tungsten core bullets to deal with the opponent's lightly armored targets. Wait.

Liu Hai will not blindly develop other guns, because we have many guns now, and developing other rifles will be considered repetitive.

Fully automatic rifles are great, but fully automatic rifles put a lot of pressure on logistics. Especially now that our inland transportation and other aspects are not very good, the Type 56 is enough.

As for another war that will happen in more than ten years, Liu Hai will just have to deal with it in advance.

In addition, there is no money. Although exports seem to be very good now, the country is big, the foundation is weak, and there are many places that need money and supplies.

As soon as this idea was implemented, Liu Hai knew that this thing could only be handmade by himself, and he was a little excited at the same time.

Xiaoyun returned to her parents' home again, because Liu Hai wanted to study on an aircraft carrier, so she first hand-made a 12.7mm sniper rifle in the aircraft carrier space, using our later Type 99 12.7mm rifle.

It's not that I don't want to use Barrett for bangs, etc., but it involves a lot of composite materials, so I might as well forget about it. There is a shortage of plastics in the mainland right now.

Xiaoyun went back to her parents' house directly after get off work. Xiaoyun's mother watched Xiaoyun come back. After Xiaoyun washed her face, she asked Xiaoyun to sit down and asked: "You have been married for so long, why is there no movement?"

"Mom, I don't know either." Xiaoyun's face turned a little red. Some people just said that the base number is larger, the success rate is higher, and they have to do it every night, so I have to make an excuse to go back to my parents' house, and I don't know what that means. Aren't you tired from working during the day?
Xiaoyun's mother said worriedly: "Is there something wrong with your health?"

"I'm sure there will be no problem. Aren't I all fine?" Xiaoyun visibly stiffened when he heard this, and then he said.

Xiaoyun's mother continued: "Or is it his problem?"

"That shouldn't be the case. Is there one in the countryside?" Xiaoyun shook his head and said.

"It's hard to tell. None of your family members are in your hometown..." Xiaoyun's mother said half a sentence.

Of course, Liu Hai didn't know that his mother-in-law was worried about these things. Liu Hai had no way to let Xiaoyun have a child for the time being. It would be 62 years soon. He would wait until she left.

When Liu Hai asked Xiaoyun to go to Hong Kong Island, he also arranged some things in advance. At least he could buy some real estate and go to sea in the 80s.

It's not that Liu Hai wants to go to sea, but that there are some things that are difficult to handle within the system. For example, Liu Hai has a lot of drug formulas in his hands. Even if he takes them out of the system, he won't get much benefit.

It's not that Liu Hai wants any benefits, but that he is not qualified to distribute the money earned from these prescriptions.In the aviation manufacturing industry, Liu Hai is still planning to borrow money, so he must have a large amount of funds.

The main reason is that airplanes involve too many things and dozens of major disciplines. Liu Hai may not be able to do it by himself in 30 years, such as design, manufacturing, etc. When the time comes, he will buy some of them and come up with some key points himself. Sexual things, now they come together.

You can develop in the semiconductor field after you go overseas. But within the system, Liu Hai is just a suggestion at most. How can you also know how to use the money bag?
Therefore, it is necessary to go to sea. This is why bangs does not involve sensitive military content. Now it involves some tanks or something at most. After waiting for more than ten years, this design of my own is nothing.

At noon the next day, when Liu Hai and Xiaoyun were having dinner together, they found that Xiaoyun was a little absent-minded and asked, "What's wrong?"

"My mother asked why she didn't have any children yet." Xiaoyun held the chopsticks in her hands, a bun in each hand, and then looked at her bangs.

When Liu Hai heard this, he said, "What's the matter? Some people only have children after seven or eight years of marriage. This is fate."

"Really?" Xiaoyun asked suspiciously.

"Of course, yes, we are both healthy and normal, no problem." Liu Hai knew that it was his own problem, so he continued to explain.

"It's just not normal." Xiaoyun said while picking up the food with a blush on his face.

Liu Hai was shocked, could it be... so he asked suspiciously: "What's wrong with me?"

"Hmph..." Xiaoyun gave her bangs a hard look.

Liu Hai now understood that he was not being serious at night, and he chuckled.

Xiaoyun hasn't said it yet, but I really don't know where you learned that.

After eating, Xiaoyun rested here for a while, and Liu Hai came to the laboratory to continue tinkering with his own things.

Liu Hai is planning to build a professional chemistry laboratory. After all, it will involve things like explosives, but let alone the chemical tools of this era.

Liu Hai had seen it in Zhu Haiyang's laboratory. The same beakers and flasks had different scales and different sizes. What do you think this is?

Of course, even in modern times, tools are said to be messy. When you buy a tape measure, you can find it in several sizes. Some tools are said to be specially used for inspection and acceptance.

In addition, Liu Hai feels that he can make some breakthroughs in pharmaceuticals. Of course, he will do the simplest things now, such as using pig viscera from meat factories to extract insulin. Liu Hai saw Coenzyme 10 written in a novel. , it feels like it’s causing trouble. It is said that this medicine is still being studied by people in modern times.

"Starting from scratch." Liu Hai really wanted the factory to import a batch of test equipment, but he wanted to report it here and then get approval from the superiors before importing.

You can make everything yourself at this time, beakers, flasks, balances, mechanical analyzers, etc. Who doesn’t know how to make them?

At least the ones you made yourself are standard, right?

At this time, the glass factory made things the same way. Take bottle blowing as an example. As long as it comes out as a bottle, even if the bottle looks substandard, it will not be reworked.

Because even if it is a defective product, it can still be sold and is very popular.

When you go to buy, the salesperson will give you all the good and bad ones, but if you have some connections, you can pick out the ones yourself, and you can pick out the qualified ones.

The beakers and flasks used in the experiment are the same. Anyway, they are only sold in state-owned stores. If you don't buy them, there is no place to buy them. It is an exclusive business. You can buy them if you like them. If you don't want to buy them, you have the ability to do it yourself.

During this period, if you buy defective industrial products, they are pretty good anyway. If there are any problems, you can just go home and fix them yourself. You don’t want a lot of others to buy them.

This is not the first time I have made measuring tools. I made measuring tools myself when I was designing. Take calipers for example. When I first entered the factory, there were not only calipers left from small notebooks, but also those from the Queen Mother period. As long as If it doesn't break, keep using it.

Because if you don’t use it, it will be gone. It’s difficult to get a new one, and the new one may not be as useful as the old one.

First make the molds, beakers, flasks, and test tubes, and draw the drawings first.

All graphs can be drawn through mathematical calculations, such as different beaker calibers and heights, different flask calibers and heights, and then alcohol lamps, mechanical analyzers, and even microscopes and Liu Hai are prepared to do it themselves.

When Zhu Haiyang was studying antifreeze, he would check all the test tools himself first, and some would have to re-draw the scales himself.

"It's better to rely on others than to rely on yourself." Liu Hai was tinkering with chemical tools in the laboratory. As for designing guns... ahem, Liu Hai is willing to take out that thing, not to mention a month, but half a month.

After all, it was copied, so Liu Hai didn't worry. He could just take it out at the end of the year or the beginning of the year. It just so happened that chemistry would definitely involve a lot in the future. First, make a set of labeled test tools, or a few sets.

Sun Aiguo relaxed a little, and then he had time to come to the maintenance department and saw Liu Hai turning on the equipment and making something.

"Factory director." After Liu Hai finished making the things in his hands, he took off his mask and greeted the factory director.

"Well, how are you doing recently?" Sun Aiguo calculated that he hadn't been here for almost two months, so he asked.

"I'm working as usual here, tinkering with some small things." Liu Hai washed his hands and poured tea for the factory director.

"Li Dali and others are coming back, but they have to study for a while first." Sun Aiguo said.

Liu Hai gave the tea to Sun Aiguo and asked: "Closed learning?"

"No, I study during the day, mainly to strengthen ideological education for foreign-related personnel." Sun Aiguo explained.

Liu nodded and understood, and then asked: "Why didn't I study when I came back from a business trip last time?"

"You don't have many contacts there, and besides, they are all in the same camp." Sun Aiguo continued.

"What are you doing?" Sun Aiguo looked curiously at the parts made by Liu Hai, which seemed to be very delicate.

"Studying chemistry, I want to improve the rocket launcher." At this time, the mainland called RPG a rocket launcher.

When Sun Aiguo heard this, he became interested: "How is the research going?"
