Super military empire

Thanks to Chifeng Zhuo for the generous reward of 300 coins.

It was not until very late that Liu Yijiu gave a clear introduction to what he had learned.

Whether it is a helicopter, fighter jet, or transport aircraft, the biggest limitation for the Republic is not the design plan, but the basic material.There are many kinds of materials used on an airplane. Although some materials only use a little, this is very important.

“The aluminum alloy used in airplanes is different from that used in rockets. After all, airplanes need to be used repeatedly. This issue was discussed a long time ago. Aviation aluminum materials such as 6061, 7075 can be produced in China, but the performance needs to be improved a lot. Moreover, these two materials can only be produced in small-scale laboratories in China..." Liu Yijiu is currently planning when to get the aviation aluminum materials that the Republic has spent a lot of energy researching.

However, he has not found a chance. Jia Yiming's current main attack direction is still on the superalloy used in the engine. This kind of thing, whether it is missiles or aviation, is used in the most critical part-the engine!

The engine is the heart. Without advanced engines, everything is in vain.

Liu Yijiu faintly felt that in the underground part of the base, those research areas that Wang Shunyi took him by but did not let him see should have this research technology.

The Ninth Academy has absolutely no research on nuclear weapons itself. This Liu Yijiu is certain.This is a combat readiness reserve base, and the projects it is engaged in should not have much to do with that kind of strategic killer.Whether there are Dongfeng 5 and atomic bombs in the base, they have not been confirmed anyway.

Even the nuclear power plant inside was built by outsiders, and many equipment was brought in from outside.

The nuclear power plant can be regarded as a construction project after this.

The train was still very slow, and returned to the base again. It was late at night after they left Chengdu. Although it was late, the design room was still brightly lit.When he was away, Yang Shan and his colleagues were working hard to get some craft documents and conducting various firearm experiments.

Liu Yijiu made a military order in this regard.

In order to make the research progress of multi-passage missiles faster, Cao Zhijiang and Liang Qiang both ate and lived in the laboratory, and Jia Yiming never came out after entering the cave.He wants to find the time lost in these years.

"You kid, you don't sleep in the middle of the night, why did you come here?" Jia Yiming lost a lot of weight, his eyes were bloodshot, his appearance was haggard, but his spirit was in a state of excitement. His face was extremely pale...

"Teacher Jia, you haven't slept for a few days? If this continues, it is estimated that you will be worn down before the superalloy formula is improved..." Liu Yijiu regretted telling Jia Yi the special superalloy formula for aviation Naruto.

These experts are the wealth of the country.

Without them, it would be extremely difficult for China to go further in these areas.

The United States was only in the 1970s to study the use of new production processes to manufacture directional crystalline blades and powder metallurgy turbine disks, and the progress is not very large now.High-temperature alloy components such as single crystal blades are mainly used to meet the needs of increasing temperature at the inlet of aero-engine turbines.

The Republic is even more difficult to produce the most basic nickel-based superalloys. After all, this aspect only started in the mid-1950s.

The top expert in this regard, Director Yao Tongbin, was beaten to death again, causing Premier Zhou to drop his teacup during a meeting. Anyone with a discerning eye can see how great the loss is.

Jia Yiming is another Yao Tongbin in the Republic. Of course, this refers to the technical aspect.

Liu Yijiu hopes that he can get some superalloy formulas for later generations and carry out large-scale production, so that no matter whether it is a rocket engine or aero engine, he will have the opportunity to increase research in this area.Only by producing suitable materials can it be possible to change the predicament of the Republic's aviation industry.

"It's okay, I can't sleep at the moment. Xiao Liu, where did you get the information? According to the formula you provided, we produced some materials for experiments, high temperature strength, oxidation resistance and heat resistance Corrosion performance, fatigue performance, fracture toughness and other properties are improved by more than 60% compared to the original ones..." Jia Yiming doesn't care how long he hasn't rested at all.

Researchers, when their own research makes breakthrough progress, if they do not get the final results, they will never stop.

Can't stop at all.

In a phrase that will be popular in the future, the people on earth can no longer stop their enthusiasm for research...

"By the way, what are you going to do when you come here?" Liu Yijiu's formulas were all put forward very secretly.For those who do not know how to do it, what he put forward is just some ideas.There will be no impact.

For experts like Jia Yiming, it is also an idea, but they can improve their experiments based on these ideas.

Equivalent to a point.

A flash of inspiration is very important for scientific research.Numerous major breakthroughs in science and technology are due to the flash of inspiration of certain scientists!Jia Yiming is an expert on some ideas put forward by Liu Yijiu, so he can pay attention to it.

Now, there is finally a return.

"It's okay, Jia Ling can't come in here, she asks me to persuade you..." Liu Yijiu hesitated for a moment, but still didn't say what she wanted.

"Don't say this. If you have something to say quickly, although we have not been in contact for a long time, I still know you better. Just for this, you won't come to me in the middle of the night..." Jia Yiming I don't believe that Liu Yijiu was just trying to persuade him to rest earlier.

"Really. I followed Director Wang and the others on a business trip to Rongcheng these days. I slept in a mountain city during the day and couldn't sleep at night..." Liu Yijiu saw Jia Yiming not believe it, and could only talk nonsense.

"I can't sleep anyway, let's discuss it?" Liu Yijiu is not as simple as it seems. Although he doesn't know where his knowledge comes from, he also knows that it will definitely not be simple Learned from a teacher.

If you could learn these from university teachers, all aspects of the Republic, how would this be?It is entirely possible to mass-produce talents in various related fields...

Liu Yijiu was immediately depressed when he heard this.

What he knew about the superalloy was almost dug out by Jia Yiming silently.Discuss again now?

These things are doubtful enough!Let’s talk about it, the old guys from the Academy of Sciences have to grab and slice him!

"Mr. Jia, I don't know much about superalloys, really..."

"Let's just say, you don't know much, you know more than I have done for decades. If it weren't for some of your suggestions, who knows how much time and cost we need to achieve the current performance?" Jia Yiming suddenly disagreed with Liu Yijiu’s statement, "Xiao Liu, I know you don’t care about fame, but you have to consider the promotion of these materials to the entire national defense industry system! Would you like to see the country because Weapons and equipment are inadequate and continue to be oppressed by Soviet revisionism and American imperialism? Our Republic has been oppressed by imperialism for hundreds of years..."

Hearing that Jia Yiming was about to give himself a history and politics class, Liu Yijiu suddenly started to get a big head. He quickly said his intentions and interrupted Jia Yiming to give him a history class.

"Mr. Jia, in fact, the purpose of my coming is because I have some ideas about aviation aluminum..." Liu Yijiu hurriedly said some of his knowledge about aviation aluminum.

Aviation aluminum is another important material in the aviation and aircraft industry.Most of the materials of the aircraft are made of this kind of high strength and light weight.Otherwise, if the plane can't fly several times with ordinary materials, it will be useless due to material fatigue.The material is too heavy, even if the plane flies, it is of little use...

"Improving aviation aluminum? There is no problem with our current materials for missiles? Is it?" When Liu Yijiu said that he wanted to improve the formulation of aviation aluminum, Jia Yiming suddenly thought of a possibility.

"Not necessarily, but we can prepare for this. On the way back, because I heard the current progress of the Zhi-6 and Zhi-7 projects, plus this time I got a lot of money from the Rongcheng Military Region. Funding, so they want to do this..." Liu Yijiu told Jia Yiming about the situation.

Regardless of whether you are able to do this in the future, you can make preparations in advance.

Materials are the key. The development of any technology and equipment is inseparable from advanced materials.

"Since it's not necessarily, we are starting to develop in this area now, is it a bit inappropriate? Manpower and funding are all problems..." Jia Yiming frowned and said.

Liu Yijiu is not the manager of the base. Since he proposed this, Zheng Hao and the others will definitely agree.But in this way, researching these unused materials is a bit wasteful.

"Materials are the foundation. Whether they can be used or not, they need to be studied. What's more, these aluminum alloys are not only used in the aviation industry, but also in the aerospace industry. If our missile shell uses the same weight of aluminum alloy strength Higher, we can install more efficient engines..." Liu Yijiu shook his head, not thinking it was a waste.

As long as you have money, you must invest in basic research first.

Otherwise, when you need it later, if you don't have the most basic materials, it's useless.

"Have you experimented with this formula?" Jia Yiming didn't ask Liu Yijiu where these formulas came from.Instead, he directly asked if he had tried it.

"No, these are some of the solutions I thought about when I was bored when I was in school. I don't know if it will work or not..." Liu Yijiu must have never tried it.
