Time passed day by day, and soon it was the end of December.

Approaching the Spring Festival, whether it is government staff or scientific research workers, or company leaders or ordinary employees, in the last month, everyone is like a clockwork, working overtime and busy in their posts, eager to finish the work of three months in a month.

As for Liu Feng, whether it is the Kirin 2nd generation supercar, or the entire antimatter engineering and aerospace engineering, all the work has been arranged, and many things no longer need to be directly involved in him, the project leader.

The design of the Kirin 2nd generation supercar has basically been finalized, and after Liu Feng sends the design drawings to Miss Zhou Yue, it will be fully handed over to Fengyue Automobile Company to operate, and it is expected that it will officially appear on the stage as soon as after the Spring Festival.

Of course, the last time he did a wind tunnel test was transmitted to the Internet, the publicity activities on the Internet have already begun to warm up, and Fengyue Automobile Company has also received many calls from local tyrants, so that the Kirin 2 generation has become popular in advance before it has officially debuted.

Many local tyrants even offered high prices and wanted Professor Liu to build a luxury supercar for them personally!

The result is naturally impossible.

Not to mention whether Liu Feng has this interest, even if he does, he has now shifted all his attention to the development of antimatter engines, and even the second generation of Kirin has already handed it over, so naturally he no longer has the energy to earn pocket money.

As for the prototype building of the antimatter engine, it is not a simple matter after all.

Although they have a full set of design drawings and the processing equipment in the laboratories of the Power Research Institute is also strong enough in the field of industrial research, there are still most things that they cannot produce.

For example, some precision sensors are purchased from professional military industrial groups through Zhang Qin;

Another example is the 'combustion chamber' material of the pulsed energy engine, although Liu Feng designed it, but he searched all the material production units in China, and none of the enterprises could produce it in large quantities, so he could only build special production instruments by himself and create several specialized material production companies.

In addition to these fields, there are also some medium and large castings that are even more troublesome.

Six o'clock in the morning.

Mukden International Airport.

A bright silver flight slowly landed on the runway, taxied along the smooth runway for some distance before landing firmly on the tarmac.

The sky was already dark, looking at the northern city outside the cabin, Liu Feng suddenly became angry, and opened his mouth to talk to Academician Chen Xuedong next to him: "To be honest, it is the first time for me to come to such a northern place. ”

Looking out the window, Academician Chen said, "I've been here several times. ”

"Oh?"

"After all, it is a traditional old industrial base, and before the construction of the southwest, this side is a well-deserved cradle of heavy industry. You know, in our business, you need to deal with these things a lot. ”

Liu Feng nodded: "Then how do you feel about this?"

"Feelings? You're talking about the senses. ”

Academician Chen was stunned, and suddenly shook his head and said,

"To be honest, it's not very good. Although this is the cradle of the heavy industry of the Republic, it was once, and now it generally gives people the feeling of being like an old man in the twilight, and I always feel that something is missing compared to the vigor of the southwest. Of course, maybe it's because I haven't been here for long......"

Nodding.

Perhaps this is not a question of the length of time Academician Chen has stayed, but the overall environment.

I don't know how many years have been shouting the slogan of revitalizing the old industrial base, but except for a small number of military industrial enterprises that can still be "tough", compared with Kannai, most of the heavy industry enterprises are still declining.

The two didn't talk for long.

After getting off the plane, a black Mercedes-Benz business car stopped at the door, and several men dressed in very low-key clothes got out of the car, opened the door for Liu Feng and Academician Chen, and sent them to a special place in Fengtian Industrial Park.

This time, the driver was not Geng Tang, but someone sent by Huaguo Aviation Industry Group.

I heard that Professor Liu and Academician Chen Xuedong came here in person, and this is a sensitive base, so their security work is quite strict, and even Liu Feng and others came here for a meeting, nominally to attend an academic lecture at Fengtian University.

I got out of the car at the gate of the destination and was greeted by two men waiting at the door.

The man at the head smiled, and stretched out his right hand from afar.

"Professor Liu, long time no see!"

Holding his right hand and shaking it, Liu Feng also smiled and said, "Long time no see, Mr. Huang." ”

This Mr. Huang's name is Huang Qihui, and he is at the helm of the entire aviation industry group, and when he held a conference at the Diaoyutai State Guesthouse last time, Liu Feng had a brief conversation with him, but he didn't expect to go to Fengtian 606 in person this time, just to greet him?

After letting go of his hand, he saw that Mr. Huang looked at the old man standing next to him, raised his right hand slightly, and introduced:

"Professor Liu, this is the chief engineer of our Fengtian Aero Engine Research Institute (606 Institute), the famous academician Qiao Yuanliang. ”

"What a big name, our little name is far worse than Professor Liu. ”

The old man was in good spirits, smiled, and took the initiative to shake hands with Liu Feng and greet him.

"It's better to see than to hear, I've heard of Professor Liu's name for a long time, and this time I finally met the real person, and I'm glad to be there. ”

"Where, Academician Qiao is polite," he shook the old man's outstretched right hand, and Liu Feng also said with a smile, "You are an old-timer, in front of you, it should be said that it is us juniors who are fortunate to meet." ”

Huang Qihui said with a smile: "Okay, let's not be polite, you guys got off the plane so early, you haven't had time to eat breakfast, right? Although the conditions of our 606 Institute are not as good as those of the high-energy institute, we can still afford a ton of hot breakfast." ”

"Haha!"

The group quickly reached a consensus.

None of them were particular people, and a few people were in a corner of the cafeteria, eating a simple breakfast, chatting casually, and soon talked about aero engines.

In the small talk, Liu Feng also had a deeper understanding of 606.

After more than 40 years of construction and development, it has developed into the largest aero engine research and design center and high-tech development base in China, integrating science, industry and trade, and has a one-stop system from product development to pilot test, production, sales and technical support.

As for this academician Qiao, he is a big man in aero engine design and reverse engineering, with more than 30 years of experience in engine design and reverse engineering, although Academician Qiao has retired to the management in recent years and rarely participates in the front-line research and development work, but there is no doubt that the independent research and development of domestic military engines is largely in the next step of this reverse engineering.

The contribution of the old man to the domestic engine is great!

So, when it comes to engine reverse engineering, the old man's interest is quite high:

"The so-called reverse engineering is just to disassemble and analyze the aero engines of other countries, understand their specific technologies, key components and materials used, crack and imitate and track research, and at the same time find countermeasures or make targeted improvements and enhancements to their own engines. ”

"In fact, it's not just the engine, the acquisition and cracking of military technology in a similar way is a means that all countries in the world are doing, to put it bluntly, copycats are not the patent of backward countries. ”

"For example, part of the nuclear weapons manufacturing technology in the pre-Mao Bear period was stolen from the people of country M. And Western countries such as country M often obtain the military technology of the woolly bear country in this way. ”

"The most typical is that in the 70s of the last century, Belenko, the pilot of the Hairy Bear Country, defected to Toray in the most advanced MiG-25P fighter jet. At that time, the MiG-25 was the world's fastest and highest interceptor fighter, and it was once one of the most feared things for the people of country M. The final result was that after reverse research, country M and Toray fully understood the advantages and disadvantages of this type of fighter, and put an end to the myth of the MiG-25. ”

"Of course, reverse imitation is not something that anyone can do, and it is necessary to have a certain industrial base and technology accumulation, and have an excellent technical team to obtain the desired military technology. ”

"It's just that with the rapid progress of technology in recent years, it has become more and more difficult for us to reverse engineer foreign aero engines. ”

Speaking of this, the old man was a little emotional, and couldn't help but reveal some inside stories to Liu Feng that are usually difficult to say.

"For example, let's not just introduce the Su-35 before. Even if we get the physical object for reverse engineering, we can't decipher some key and core technologies, such as materials, avionics, and ...... Wait, a lot of things, or can only rely on our own long-term research and development and technology accumulation, and also have excellent processing technology. ”

"Especially a certain material of the engine, we have clearly cracked its composition, but the same proportion of ingredients, because of the different manufacturing processes, ultimately leads to the things we make, compared with others, in terms of performance, it is much worse......!

"Therefore, it is undeniable that the acquisition of military technology through reverse engineering is a way to gain inspiration and a better understanding of design concepts and technical details. But in the end, if we want to make a breakthrough in military technology, the key is to base ourselves on our independent research and development and independent innovation, and we must work hard power. ”

"At this point, we old things, it's far behind! I have to rely on you young people, especially Professor Liu, I admire you very much, the pulsed energy engine, gave us the production drawings, and also gave us the material formula, but in the end we can't process it, and the accuracy of the castings can't meet the standard!

"If I didn't know where this thing was used, I would have thought that Professor Liu was deliberately embarrassing us...... Anyway, our 606 Institute has already held its breath, just waiting for Professor Liu to show up and give an explanation. ”

Listening to the old man talk about reverse engineering, Liu Feng originally listened to it with relish, but suddenly heard that the old man had made a major reversal, and when he talked about himself, he couldn't cry or laugh in his heart.

You're here to give me a vaccination!

As for the reason why the engine castings cannot be processed, there is a saying that the processing materials provided by the 606 Institute are unqualified, or it is simply a design problem on their side, otherwise, why can they not even produce J-20 engines, how can they not even make this thing?

Could it be that this thing is more complex than a vector engine?

I have to say that if it weren't for knowing what this thing was, even Academician Qiao would have believed it a little, let alone others.

Therefore, many people are dissatisfied with Liu Feng's side, and it is not a waste of their time to take unqualified or immature things for them to process?

Liu Feng had already heard about this, otherwise he would not have come over to find the reason in person.

looked at Academician Qiao, and then looked at Huang Qihui next to him, Liu Feng probably knew why this person also appeared in the 606 Institute......

The overall annular casting of the engine is related to the stability of the entire engine structure, and it is necessary to ensure that these castings are relatively light, and at the same time, it is also required to ensure their tensile strength, fracture toughness, corrosion resistance, high temperature resistance and electromagnetic resistance and a series of properties.

The outrageously complex processing technology is not much better than that of an aero engine.

It's just that at the beginning, the 606 Institute was quite confident in processing this thing.

As the largest aero engine development and production base in China, if they can't process it, there will be no place in China to get this thing out.

What's more, they have also handed over the drawings and material production processes to them.

However, the truth is quite unexpected......

606 institutes, CNC machining centers.

Huge five-axis linkage CNC machine tools, like an army of transformers, are neatly arranged.

Five-axis linkage CNC machine tool is a kind of high technology content, high precision, specially used for processing complex surface machine tools, this machine tool system has a decisive influence on a country's aviation, aerospace, military, scientific research, precision instruments, high-precision medical equipment and other industries, it can be said that to a certain extent represents a country's equipment manufacturing capacity.

The frame, blades, heavy-duty rotor, combustion chamber and carbon sail of the pulsed energy engine can only be machined by these machines.

Therefore, after breakfast, Liu Feng and the others went straight to the point and came to the processing center in a hurry.

"Professor Liu, we have tried to process 6 or 7 times, but no matter how we adjust the performance of the machine tool, change the priority program of machining, and even change the operating engineer several times, we still can't process the accuracy ...... that meets the requirements of the drawings."

The person in charge of the scene glanced at Liu Feng and the two leaders beside him, and couldn't help but shake his head helplessly.

"Have you found the reason?"

"Sorry, we tried our best. ”

In addition to helplessness, the person in charge is more ashamed.

At the beginning, they kept saying that they could complete the task, but as a result, they wasted so many precious materials, and they never met the standard, and the key is that they couldn't even find out the reason!

606's face is about to be lost by him!

However, there are always people who like to shake the pot and don't find the reason from themselves.

In this regard, he is quite helpless, and he feels exhausted, because every character in the CNC center is an uncle......
