Take Off My Aviation Era

After hearing what Lin Guanghua said, Zhuang Jianye was a little surprised. He really did not expect this guy to have such a miserable life in the second workshop of the final assembly. He should be divided if he is done well. After all, the chief engineer personally explained that he did not take it seriously. The truth.

　　 If it fails, it will be Lin Guanghua’s responsibility. As the second assembly shop said, they lacked such talents, so Lin Guanghua was transferred. Since it can’t be done by this talent, who else can it be?

If you can’t figure it out, it’s very simple. Just go directly to the 23rd branch. Since you have taken the responsibility, you have to bear the consequences. As for the tasks assigned by the chief engineer, you can find someone else. With so many college students coming, there are always people who are taking advantage of them and are willing to take the tank.

　　 Zhuang Jianye really sympathized with the man in front of him. He climbed up with his mind and thought, but the result was good. He suddenly climbed into the fire pit and couldn't get out.

Seeing that Zhuang Jianye only showed sympathy, but did not speak, Lin Guanghua was finally anxious. Zhuang Jianye was the only person in the factory who proposed the brazing process. It would not be an exaggeration to say that it was his last straw. If Zhuang Jianye could not help, then he would You can only go to the twenty-third branch in a blanket roll. Just think about the educated youth who return to the city who even the police have a headache. Lin Guanghua only feels that the future is gloomy.

　　 So he was ready to summon the courage to ask for another request. Just at this moment, he saw the manuscript on the table with several large crosses, and his eyes lit up and he said: "Are you writing a paper?"

　　Zhuang Jianye nodded: "Yes!"

Lin Guanghua’s hurriedly and mysteriously continued: “My teacher at the university has recently been transferred to the editorial department of the Journal of Aeronautics and Astronautics. We have a good relationship. As long as you help me, I guarantee that your paper will be published as long as it is not well written. In the Journal of Aeronautics."

　　 The Journal of Aeronautics is the core journal of the aviation industry. Zhuang Jianye hasn't published an article on it in two lifetimes. If it weren't the case, he wouldn't have to spend so long in his previous life.

Unexpectedly, when he was about to write a paper in this life, someone sent an invitation from a core journal. Zhuang Jianye said that he was not tempted. It was false. You must know that his old husband forced him to write a paper for publication in order to continue to promote and publish in the future. The larger the publication of the paper, the more confident you will be promoted in the future.

But after thinking about it, I quickly rejected it. Nothing else, just because Yonghong Factory really lacks the application basis of related processes. After all, the brazing process of aviation products is different from ordinary industrial products, and each step is strictly not mentioned. , The difficulty is also very large.

　　 It’s okay if you have time to take it slowly, just one week is too short, even if the gods descend to the earth, they can’t do it.

　　 then shook his head: "The time is too short, and the factory lacks supporting hardware. Really, it's not that I won't help you, there really is no such condition."

Lin Guanghua's face turned gray when he heard it. Zhuang Jianye was telling the truth. Yonghong Factory had never used the brazing process, and used the old-fashioned welding process of the Soviet Union in the late 1950s. The lack of hardware and equipment is the biggest limitation. The theory is so bullish, without practical verification, it is still not convincing.

Realizing this, Lin Guanghua finally accepted his fate, thinking that he would go to the 23rd branch in the near future, he felt sad and sighed, with a hint of decomposition, as if he was about to solve the mystery. , Asked: "Then can you tell me what hardware is needed? Even if I get stuck, I have to figure out where I planted it!"

Zhuang Jianye filled Lin Guanghua’s empty tea jar with water, and he looked at Lin Guanghua pityingly: “I won’t talk about the vacuum brazing furnace. Our factory doesn’t have it at all, but it doesn’t matter. The welding research institute in the province has It’s a small experimental furnace. Anyway, the labyrinth has a small cover and can barely be used. The key is the material!"

　　 Hearing that there is a place to replace the key equipment, Lin Guanghua's disappointed eyes gradually recovered, and he hurriedly asked: "What material?"

　　 "Metal felt!" said Zhuang Jianye.

　　 Lin Guanghua was stunned when he heard the words, and immediately asked about the specific situation of the metal felt. Since everything is said to be the case, Zhuang Jianye also introduced the situation of the metal felt.

The so-called metal felt is a material made by non-woven laying, stacking and high-temperature sintering of metal fibers. Because of its good filterability, the general metal felt is generally used for polymer filtration, electronic high-temperature gas dust removal, etc. field.

However, aviation-grade metal felt is not only a filter, but an excellent sealing and gasket material. It should be known that due to the unique structure and working environment of jet engines, the materials used must be durable and light, and at the same time Have to ensure safety.

Therefore, the general gasket sealing material is not suitable for aero engines at all, so people think of using some durable metal alloy sintered metal felt to play this important role. Among them, the most widely used is a chromium-nickel ratio between 0.25 and 0.408. The alloy metal felt with carbon-nickel ratio between 0.12 and 0.15.

　　This kind of metal felt can not only withstand the high temperature of nearly 900 degrees Celsius, but also has a very good sealing effect~www.readwn.com~Zhuang Jianye has used this material several times in his previous life, and the effect is very good.

　　 It's a pity that this kind of material can't be produced in China. As for the preparation process of the material, it is a science and technology tree that has gone straight to the sky. Zhuang Jianye's job has not yet figured it out, so naturally he can't understand other things.

　　 Because of this, even if he writes the craftsmanship of the top cover of the maze clearly in black and white, it is no use. It is difficult for a clever woman to cook without rice, and it lacks key materials.

That’s why, he avoided the old man after Mr. He was perfunctory, and he didn’t talk about the brazing process on weekdays. There was no way. There was really no such conditions. He could not deal with it, so he was beaten in the face. Why bother .

　　 But looking at Lin Guanghua's reaction, it seemed that he still didn't give up. The burning eyes looked like he wanted to give it a try.

　　 "Are you sure that the composition of that kind of metal felt is that the ratio of chromium to nickel is between 0.25 and 0.408; the ratio of carbon to nickel is between 0.12 and 0.15?" Lin Guanghua asked.

　　 "Yes, what? You have?" Zhuang Jianye asked back.

　　 "I don't have one, but my wife has!" Lin Guanghua replied.

This time Zhuang Jianye didn’t speak, but looked at Lin Guanghua in amazement. Lin Guanghua understood and immediately explained that Zhuang Jianye understood that the number 10 project that this man’s lover participated in had tested a lot of high-performance aviation materials during this period. They are all rare imported products in China, including the metal felt just mentioned.

　　 It’s also a coincidence that these days, Tang Lili often brings materials home to rush to work. Lin Guanghua accidentally saw the situation about metal felt, and even calculated a standard constant for his wife by himself, so that’s why she was impressed.

　　 There is such a coincidence in the world. If you want to sleep, someone will give you a pillow. Zhuang Jianye can't be surprised if you don't want to say anything, and you're done.
