Super military empire

Basic materials are the key to the development of all mechanical technology and equipment, especially some very important top materials.

These materials are not sloppy at all. Liu Yijiu knows these people's ideas, first come up with one to solve the current dilemma, and then slowly come up with the same, and continuously improve.This is the path taken by various countries, so that a lot of experience and technology can be accumulated.

But he can't wait.

If you want to prepare for the next fighter, you must work hard on the superalloy.The aviation industry of the Republic is largely restricted by this material.The research work on Turbofan VI has ended. If it weren’t for Yang Wei who stole the Tu-22m2 Backfire from Lao Maozi, the fate of this team would be the same as before. It would be split, and part of it would go to the large aircraft factory in Shanghai , One part entered Qin Fei, the other part entered Shen Fei.

Now, after the measurement of the Backfire bomber is over, they will start a new generation of engine research. Lao Maozi’s engine technology is far beyond the reach of the Chinese. Even the Americans are older in this respect. The fur is even worse.

And this engine technology is based on advanced superalloys.

The working temperature is very high, at the same time, the working conditions are extremely bad, and the service life is very long. This is not a problem that the Republic of China has reached the threshold of 760°c high-temperature alloy. More than two hundred hours.

The cost of an engine will be millions of dollars. If this is the case, the produced engine will make the flight cost of the aircraft more than ten thousand dollars on the engine alone. This is a double engine. The heavy fighter jets cost five thousand dollars an hour!

How can the poor Republican Air Force bear such high flying costs?

Liu Yijiu discussed with Zhao Maoping all the way, and soon entered the research workshop where Jia Yiming was.This workshop is the largest base in the entire second zone. In it, there is not only a complete physical and chemical analysis room, but also various process equipment from the beginning to the sintering of materials.

"Teacher Jia, what's wrong with you? How many days have you not rested?" Liu Yijiu doesn't have too much time to see Jia Yiming now. This old man is in the second district. His original dormitory is in the third district. The school in the base goes to school, and the lodging is over there. Jia Ling entered the firearms research and design room in the third district, but he made a home in the second district.

"Are you here? I have been thinking about how to improve the purity of various materials. There is no problem with these chemically purified materials. The key is that the smelted materials cannot be used now." Jia Yiming did not regard you as an ordinary technique. Researchers.

Shi Changxu was also very accomplished in superalloys. After Yao Tongbin was killed, he led the research team to work on the top materials needed for the entire Republic of aerospace.

"Electroslag furnace remelting technology. If we want to produce gun steel, we must use this furnace to remelt the refined materials again, so that the steel obtained will further reduce impurities..." Liu Yijiu sighed .

At the beginning, he was so busy that he forgot to talk about the remelting of the electroslag furnace. Wang Shunyi was also busy with the missile project on his side all day. He wanted to make a better missile, so he forgot, Zheng Hao hadn't been in the base at all, so he couldn't count on him.

Originally, Liu Yijiu thought that there was no such technology in China. Knowing that the Shanghai Heavy Machinery Factory had such production technology since the 1960s, he was always thinking about when to start producing an electroslag furnace there. The equipment is back.

Without this thing, their new cannon steel would not come out.

"That thing can really be useful?" Jia Yiming obviously doesn't believe this. The material Liu Yijiu provided is not available in China. Where did he get it from? Jia Yiming doesn't bother to ask, as long as he can He was satisfied to get the materials out and speed up some domestic research progress.

"Why is it useless? Tank and gun steel are purified by electroslag furnace remelting, so that the performance can be doubled! Aren't our domestic 541 and 617 all using this technology? New gun steel, since impurities Many, it is also possible to use this method for further purification..." Liu Yijiu was a little confused, Jia Yiming and the others would make such a mistake?

Hearing what he said, Jia Yiming suddenly patted his head and said annoyedly: "I knew this way, I don't need to think about using chemical processing to obtain these material elements..."

Liu Yijiu rolled his eyes when he heard this.

Such top-level big players will make such low-level mistakes?

Isn't this incredible?

"After the New Year, let’s send someone to the Shanghai Stock Exchange to get a set of equipment from there. Let’s try again when the time comes. This is about to be the New Year’s Day. It is estimated that there will be a holiday there too. It’s useless to be anxious. Let’s do other theoretical research first, especially the design of the equipment we need for superalloys. Importing these equipment from abroad is expensive, not to mention, we have no foreign exchange at all! They all know what these gadgets are used for. Naturally, they will not be polite to us..." If you want to introduce superalloy powder metallurgy technology and equipment, even because it is in the early stage of honeymoon period in Chinese and Western countries, Liu Yijiu There is not much hope.

Superalloy, which is necessary for aerospace and aviation, without this thing, jet engines cannot be manufactured.

There have been many research results on superalloys in China, but these superalloy materials have no way to make the engine have a higher service life. The superalloys used for intercontinental missiles only need to be used for one hour at the operating temperature of the rocket engine. Less time is enough, at most more than an hour, general superalloys can achieve this performance.

Aircraft engines are different. They need to be used repeatedly. As a result, the requirements for materials for such aircraft engines are much higher than those for rocket engines.

"How many years are we waiting for, let's go over there now! They should not have a holiday for the New Year? The whole country is full of waste and waiting!" Jia Yiming has not worked for many years, and now he resumes work. After a period of adaptation, I threw myself into it.

Just like the others in the base, they were wasted too much time.

"We don’t have holidays here, it doesn’t mean they don’t. If there are not enough production tasks, their usual work may not be full..." For the Shanghai Heavy Machinery Factory, Liu Yijiu knows that the situation of this factory is now It's not that good.

The country's investment in the aviation industry is not very large, especially many aviation projects are now facing the dilemma of dismounting.

Liu Yijiu chatted here for a while, and now he dare not disclose some materials and craftsmanship, on the one hand, to prevent Jia Yiming and the others from exhausting, on the other hand, to prevent himself from revealing too much. He couldn't explain the source of many things.

Just relying on his teachers, it’s impossible to justify it. He did it out of things that none of his teachers did. He did not see what experiments or research he did. In the end, others smelled it. What to say?Can't explain it.

Just as his teacher, Mr. Qian Xuesen, is also an expert in nuclear physics, this is only known to a few people, and outsiders only know that he is an expert in missiles.Zhu Guangya, Liu Yijiu's other teacher, respected him very much.

Can someone who can talk to Zhu Guangya not make a difference?

The book "Engineering Cybernetics" written by Qian Lao that year, Chairman Mao admitted that it is a heavenly book!

Those who don't know how to do it can't master these professional knowledge at all.

"However, without these materials, our engines will not be able to get them. The missile is not a problem, but the problem is the aircraft? Unless we do not engage in aircraft engine projects, the turbofan six project team has been unable to make progress because of the materials. So..." Zhao Maoping is also very concerned about this matter.

Their ambitions have now expanded to the direction of acquiring key materials for aircraft engines.

The Republic knows how strong the demand for new types of aircraft is.

"This matter can't be solved in a short time. Anyway, the Turbofan VI team is still working on the Turbofan VI in Rongcheng. To get the engine of the Tu-22, there is no need to start it in half a year to a year... …" Liu Yijiu sighed.

He is more anxious than anyone else.

The sooner these technologies are developed, the less arrogant the United States will be after the collapse of the Soviet Union.

If he dared to drive the aircraft carrier to the door of the Republic to conduct military exercises, then the Republic directly dispatched a group of bombers and fighters with low-altitude supersonic penetration capabilities to also exercise in that area, flying over their aircraft carriers. Time to see if the Yankee can pee his pants.

The Republic pursues a defensive strategy and will not actively attack any country.

"How long will it take for our new aircraft to go to the sky again!"

"There is no way to do it. If you have a chance to get it out, it's almost the same. Wait for the static pressure equipment to get out first, and large-scale high-frequency furnaces and vacuum induction furnaces must also be out. We will develop a variety of high hardness and high strength in the future. For materials, there is no other way except powder metallurgy. The melting points of various material elements are different, but there is a way to melt some materials, and eventually the performance will be changed because the other matched element materials exceed the boiling point...
