Chapter 287 There are many of them, but they are not necessarily strong
Silk? This moment made the two people at the Changjian Factory confused.
One of the technicians probably had a short circuit in his head and asked, "Director Gao, silk is afraid of fire."
As soon as he finished speaking, he quickly shrank his neck.
Because he saw Mr. Luo from his factory looking at him like a fool: "Enameled wire, rubber, and plastic are all afraid of fire. What's the difference between them and silk? And you forgot that in Director Gao's configuration, gas is Discharged sideways? ”
It can only be said that this comrade thought about it, but not everything.
The above materials also have flame-retardant or flame-retardant models, but flame-retardant and fire-proof are actually two different things. Just look at the relevant standards and see if these types of materials exist these days. It’s hard to say.
However, the starting point of his concerns was okay. He just forgot that Gao Zhendong had already communicated with them the configuration of the missile, and there was no need to consider this issue at all with that configuration.
You really need to consider this for other configurations, such as the Chijian-8. Its engine spits fire from the rear, and the wires must be burned by the flames.
However, the solution of Chijian-8 is also quite interesting. It rotates the missile and uses the power of rotation to throw the wires in a spiral shape around the missile body to avoid the area where the fixed jet is fired.
Luo Gong turned his head and said to Gao Zhendong: "Director Gao, is silk strong enough?"
Gao Zhendong smiled and said: "The tensile strength of silk is higher than that of copper wire. This only considers the cross-sectional area. , regardless of 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 mechanical properties of silk and copper wire. the difference.
Generally, the tensile strength of copper wire is 200Mpa~500Mpa (MPa), pure copper wire is only 220Mpa, and silk is about 400Mpa~600Mpa. Putting aside the weight factor, it is already stronger than Copper wire is much better.
Moreover, the elongation rates of silk and copper wire before they are broken are almost the same, 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 can be stronger than it. For example, spider silk is stronger than it. However, spider silk is also a typical thing that is well received but not popular, even when Gao Zhendong traveled through it. At present, it is probably a situation where the thunder is loud but the raindrops are small, because raising spiders is much more troublesome than raising silkworms, especially large-scale breeding.
Having introduced this point, Gao Zhendong added: "In addition, considering that the proportion of cooked silk is only about 1.3, compared with the proportion of copper wire as high as 8.9, you can imagine how useful silk is for wire reinforcement. It’s a good material. Moreover, after silk treatment, the performance is relatively stable, which solves the problem of long-term storage.”
As for how to deal with it, let the people of the Changjian Factory figure it out. The answer depends on the process, and they will still know it. This is not a math question. Even if you know the answer, you can’t deduce the process.
The people at the Changjian Factory were very excited after hearing what Gao Zhendong said. Although they haven't tested it yet, just listening to Gao Zhendong's well-founded introduction, they were basically sure that this thing was reliable.
Mr. Luo smiled and said: "Listening to your words is better than ten years of reading. Why didn't we think of silk? This is our traditional feature. We didn't think of it. It's our fault that we don't have the basics." Prison.”
Maybe it's just too traditional, and sometimes I can't think of it because I haven't thought 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 disconnection problem, the time it took to be troubled by this problem also took years to calculate.
After Gao Zhendong finished talking about the solution, he immediately started to act as the shopkeeper: "I don't care about the specific matters. You can find a way to solve them. I think our textile industry is not bad. The remaining specific matters, You should contact the relevant units and we should be able to solve it."
Mr. Luo of the Changjian Factory repeatedly said: "That's for sure. Director Gao, you have paved the road so well, and we still can't figure it out. , then I will stop being the chief engineer, and our factory will stop thinking about developing all products. The whole factory will go home and eat old rice as soon as possible.”
With a clear technical route, Mr. Luo is really not afraid of not being able to make it. The main problem with this thing is the material problem. Once the material is determined, as for the other things, it is not difficult. It is not that there are no textile factories where the Changjian Factory is located. The choice of silk and the The problem of coating on such a thin copper wire is probably a problem.
Gao Zhendong handed the finished drawing of the solid rocket motor shell to Mr. Luo: "This is the solid rocket motor shell. It has basically been finalized. You can make the shape of the full rocket based on this." design, as well as the related design of the packaging launch box.”
Although the entire engine has not yet come out, this part can already be used by the people of the Changjian Factory to carry out detailed design of the overall configuration. People were overjoyed.
Originally, I was just here to solve the problem, but I didn’t expect Director Gao to act so quickly. Gufa has already achieved some results, which is enough to support their next work.
Looking at Gao Zhendong alone, and then thinking about his group of people, the comrades in the Changjian Factory are very ashamed. Director Gao is busy with the design of fixed hair, and he still has to find time to solve the technical problems in his factory. , which really makes a group of people feel a little embarrassed.
Although the user representatives also participated in the meeting, they basically did not speak during the whole process, but the smile on their faces never broke. Sure enough, it was right to cooperate with Director Gao on the project. He was trying to kill rabbits. His own work was not delayed, and he could also take care of other people's affairs.
After solving the problem of the wires, Gao Zhendong treated them to a meal in the canteen. Everyone was in high spirits. The individual anti-tank missiles and the puzzle pieces began to take shape.
Not to mention, Director Gao’s entertainment expenses are among the highest among division-level cadres in the factory. Even though sometimes he pays out of his own pocket, the connection at the unit level is No matter what, you can't let people pay for it out of their own pockets, but among division-level cadres, he encounters this kind of situation quite often.
However, no one has any objections to this. There are many guests at Director Gao's place, from all over the world, and they are all from very important units, even the kind of units that cannot be asked at all. People come all the way to ask for a meal. The hospitality is the same all over the country.
And the factory is not losing money either. Deputy Director Li, who is in charge of logistics, said: "Director Gao's training brings business to the logistics department that far exceeds his entertainment expenses." However, these things, Generally speaking, it is not put on the table.
After dinner, the people from the Changjian Factory said goodbye. They were full of energy now. A technical problem that had been bothering them for a long time had found a way out. The feeling of eagerness and impatience was very unbearable.
Before leaving, they also left behind the current results of another part they were responsible for - the warhead, for Gao Zhendong's reference when designing the fixed launch.
At least the dimensions, appearance, volume and weight are 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 is located is not far from the capital. They still came here in their own factory cars. However, because there were many people, quite a few of them came by car. In the open rear bucket, it was rocked all the way over and all the way back.
Don’t be dissatisfied. Being able to sit in this convertible is already considered a very good condition these days.
As for user representatives, they have their whereabouts and transportation methods.
Another technical backbone was sitting in the driving building with Mr. Luo. The technical backbone suddenly remembered something and showed a somewhat unclear look on his face: "Mr. Luo, our If there is a problem with the wires of the 'guerrillas' copying the SS.11, then the regular army that is engaged in heavy bombs will also..."
Mr. Luo pursed his lips: "Don't tell me, it's really possible, Gao The anti-tank missile of the Gallic Chicken is really deceiving.”
In this regard, the SS.11 shooter of the Gallic Chicken said that you are right, but I am emotionally stable.
When it comes to the imitation process on both sides, their estimates are reasonable. Everyone's technology is on the same line. Even though the professionalism may be higher on the other side, the technical level and knowledge reserve are not actually very large. The difference is that the same problems that the Changjian Factory will encounter will probably be encountered there as well.
"Then should we notify them?"
Mr. Luo thought for a while and shook his head: "If we don't notify them, they will definitely encounter it, but maybe they can solve it. They have more technical power than us. , more professional and better than us, it should be better. Moreover, if we report it in such an inexplicable way, it can easily cause misunderstandings, which is not good. Let’s wait until the definite news comes and they will be stumped. ”
The technical backbone thought for a moment and felt that Mr. Luo’s concerns were reasonable and nodded. Then he smiled and said: "Mr. Luo, I agree that they have more technical power than us, but if you say they are better than us and more professional than us, then I don't think so. Hehe, this thing is not stronger with more people."
Mr. Luo understood what he meant. He smiled, stretched out his hand and nodded a few times: "You kid, haha, you can't say this everywhere."
Although Mr. Luo felt that he was right. It makes sense, but this tendency cannot be encouraged.
After seeing off the people from the Changjian Factory, Gao Zhendong was invited over by the factory office before he had even done any work.
When we arrived at the conference room, Factory Director Yang and Chief Engineer Chen were both there. In front of them, there was a document sent by the National Defense Work Committee to the 17th Machinery Department and transferred from the 17th Machinery Department.
It was Da Mo who asked for a batch of solar monocrystalline silicon modules.
However, the document does not indicate where the request was made, and the third rolling mill is only responsible for pulling out monocrystalline silicon crystals that meet the requirements. Other matters are not mentioned above.
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 to the ministry from the National Defense Work Committee. The ministry means that it must cooperate and be satisfied."
