Chapter 287 They are numerous, but not necessarily strong
Silk? This confused the two people from the Long Sword Factory.

One technician probably had a brain short circuit and asked, "Director Gao, silk is afraid of fire."

As soon as he finished speaking, he quickly shrank his neck.

Because he saw Luo, an engineer at his own factory, looking at him like he was a fool: "Enameled wire, rubber, and plastic are all afraid of fire, so what's the difference between them and silk? And have you forgotten that in Director Gao's configuration, the gas is discharged sideways?"

All I can say is that this comrade thought about it, but not all of it.

The above materials do have flame retardant or flame retardant types, but flame retardant and flame retardant are actually two different things. You can find out by looking at the relevant standards. It is also hard to say whether these types of materials exist these days.

However, his starting point of concern was correct. He just forgot that Gao Zhendong had already communicated the configuration of the missile with them, and that configuration did not require consideration of this issue at all.

Other configurations really need to take this into consideration. For example, the Chijian-8 has a tail-mounted flame-breathing engine, so the wires must be protected from being burned by the flames.

However, the solution of the Chijian-8 is also quite interesting. It rotates the missile and uses the force of rotation to throw the wire in a spiral shape around the missile body to avoid the area of ​​fixed jet.

Engineer Luo turned around and said to Gao Zhendong, "Director Gao, is the silk strong enough?"

Gao Zhendong smiled and said: "The tensile strength of silk is higher than that of copper wire. This is only considering the cross-sectional area, not the weight. If the weight is the same, the tensile strength of silk is much higher than that of copper wire."

Next, Gao Zhendong began to explain and introduce the main differences in the mechanical properties of silk and copper wire.

The tensile strength of general copper wire is between 200Mpa and 500Mpa (megapascals), and that of pure copper wire is only 220Mpa, while that of silk is approximately between 400Mpa and 600Mpa. Putting aside the weight factor, it is already much better than copper wire.

Moreover, the elongation of silk and copper wire before they are pulled apart is similar, both around 20%, which makes them very suitable for wrapping copper wire.

Based on these two points alone, there are not many natural fibers that are stronger than it. For example, spider silk is stronger than it, but spider silk is also a typical product that is well-received but not popular. Even before Gao Zhendong traveled through time, it was probably a situation of much ado about nothing, because raising spiders is much more troublesome than raising silkworms, especially large-scale breeding.

Gao Zhendong added: "Considering that the specific gravity of cooked silk is only about 1.3, compared with the specific gravity of copper wire which is as high as 8.9, you can imagine how good silk is for conductor reinforcement. Moreover, after silk is processed, its performance is relatively stable, which solves the problem of long-term storage."

As for how to deal with it, let the people at the Long Sword Factory deal with it. They will be able to infer the process based on the answer. This is not a math problem. Even if you know the answer, you can't infer the process.

The people at the Changjian Factory were very excited after hearing what Gao Zhendong said. Although they hadn't tested it yet, just by listening to Gao Zhendong's well-reasoned introduction, they were basically certain that this thing was reliable.

Mr. Luo smiled and said, "Listening to your words is worth ten years of reading. Why didn't we think of silk? It's our traditional feature. We didn't think of it. It's because our foundation is not solid."

Maybe it’s just too traditional. Sometimes I can’t think of it because I never think in that direction at all.

It’s not that the people at the Changjian Factory are stupid. Before the Red Sword-8 used silk to solve the problem of thread breakage, the time it was troubled by this problem was also calculated in years.

After Gao Zhendong finished talking about the solution, he immediately started to act like a hands-off boss: "I won't take care of the specific matters. You guys figure out a way to solve them. I think our textile industry is pretty good. For the remaining specific matters, you can contact the relevant units and they should be able to solve them."

Mr. Luo from Changjian Factory said yes again and again: "Of course, Director Gao, you have paved the way so well, but we still can't figure it out. Then I have to give up my position as chief engineer, and our factory can forget about making all the products. Everyone in the factory should go home and eat their old rice as soon as possible."

With a clear technical route, Mr. Luo is not afraid of not being able to produce it. The main problem with this thing is the material. Once the material is determined, as for the other things, it is not difficult. There are textile factories where the Changjian factory is located. It should be possible to solve the problem of silk selection and coating such a thin copper wire.

Gao Zhendong handed the finished drawing of the solid rocket engine shell to General Luo: "This is the shell of the solid rocket engine. It has basically been finalized. You can use this as a basis to carry out the shape design of the entire missile and the related design of the packaging and launch box."

Although the entire engine has not yet been released, this part has allowed the people at Changjian Factory to carry out detailed design of the overall configuration, which made the people at Changjian Factory overjoyed.

I originally just came here to solve a problem, but I didn't expect Director Gao to act so quickly. There have been some results in hair loss treatment, which is enough to support their next step of work.

Looking at Gao Zhendong alone and then thinking about themselves, the comrades at Changjian Factory felt very ashamed. Director Gao was busy with the design of hair extension, but he still had to find time to solve technical problems in his own factory. This really made them all feel quite ashamed.

The user representative also attended the meeting, but he barely spoke during the whole meeting. However, he kept smiling. It turned out to be the right thing to do with Director Gao. He was doing a good job, which did not affect his own work, and he could also handle other people's work.

After solving the problem of the wires, Gao Zhendong treated them to a meal in the cafeteria. Everyone was in high spirits, and the individual anti-tank missile, like a puzzle piece by piece, began to take shape gradually.

It's no wonder that Director Gao's entertainment expenses are among the highest among the department-level cadres in the factory. Even though he pays out of his own pocket sometimes, the coordination at the unit level cannot allow people to pay out of their own pockets. Among the department-level cadres, he encounters this situation quite often.

But no one objected to this. Director Gao had many guests from all over the world, and they were all very important units, even the kind of units that you couldn't ask for anything. They came from far away, so what's wrong with treating them to a meal? Hospitality is the same all over the country.

And the factory is not losing money. Deputy Director Li, who is in charge of logistics, once said: "The business that Director Gao's training brings to the logistics department far exceeds his entertainment expenses." However, these things are generally not brought to the table.

After dinner, the people from the Changjian Factory said goodbye. They were full of energy now. A technical problem that had troubled them for a long time had found a solution. The feeling of eagerness and impatience was very unbearable.

Before leaving, they also left behind another part they were responsible for - the current results of the warhead, for Gao Zhendong to refer to when designing the fixed-fire weapon.

At least the size, shape, volume and weight can serve as a reference for the detailed design of the engine.

The people from the Changjian Factory left in a hurry. Fortunately, the city where their factory was located was not far from the capital, so they still came in their own factory car. However, because there were so many people, quite a few of them sat in the back of the convertible, swaying all the way here and all the way back.

Don't be disgusted. Being able to have a convertible and sit in it is already a very good condition these days.

As for the user representatives, they have their destinations and modes of transportation.

Another technical backbone was sitting in the driving room with General Luo. He suddenly remembered something and showed an inexplicable look on his face: "General Luo, our 'guerrillas' have a problem with the wires used to imitate the SS.11. Will the regular army with heavy ammunition also have problems?"

Mr. Luo pursed his lips and said, "Don't tell me, it's really possible. The Gallic anti-tank missile is really too deceptive."

In response, the Gallic SS.11 shooter said, "You are right, but I am emotionally stable."

When it comes to the imitation process of both sides, their estimation makes sense. Everyone's technology is on the same level. Even if the professionalism may be higher on that side, there is actually not much difference in technical level and knowledge reserves. The problems that Changjian Factory will encounter will probably be encountered there as well.

"Should we notify them?"

Mr. Luo thought for a moment and shook his head. "If we don't notify them, they will definitely encounter problems, but maybe they can solve them. They have more technical resources, are more professional, and are stronger than us, so they should be better. Besides, if we notify them in such a strange way, it will easily cause misunderstandings, which is not good. When we really get definite news, they will also be stumped. Then we can talk about it later."

The technical backbone thought about it and nodded, thinking that Mr. Luo's concerns were reasonable. Then he smiled and said, "Mr. Luo, I agree that they have more technical strength than us, but I don't think it's necessarily true that they are stronger and more professional than us. Hehe, this thing is not strong just because there are more people."

Mr. Luo understood what he meant, laughed, and nodded a few times with his hand: "You kid, haha, you can't say this everywhere."

Although Mr. Luo felt that what he said made sense, this tendency should not be encouraged.

After seeing off the people from Changjian Factory, Gao Zhendong was invited over by the people from the factory office before he could do any work.

When we arrived at the meeting room, Director Yang and Chief Engineer Chen were both there. In front of them was a document that was sent to the 17th Ministry of Machine Building by the Defense Work Committee and then forwarded by the 17th Ministry of Machine Building.

It was the demand put forward by Da Mo to produce a batch of solar monocrystalline silicon modules.

However, the document did not specify where the demand was made, and the third rolling mill was only responsible for pulling out single-crystal silicon crystals that met the requirements. Other things were not mentioned here.

This compliance with requirements refers to compliance with purity, size, crystal structure, etc.

Director Yang handed the document to Gao Zhendong: "Zhendong, this is a request sent by the Defense Work Committee to the Ministry. The Ministry means that we must cooperate and meet it."
