I didn't know about such a difficult project before, and I thought that with a full set of designs, I only needed to get a prototype.

Through explanation, we can know that every technology in this is a challenge that cannot be completed in a short period of time.

Sun Hong saw Jiang Chenyang's bitter face, and he was also a little dissatisfied with Xie Kai's personal vendetta behavior, so he stood up and said, "Isn't it too ...... for such a difficult project to produce a prototype in five years?"

Originally, the project's indicators were too high and unrealistic.

Xie Kai looked at Sun Hong, and then at Jiang Chenyang, it seems that the relationship between these two is not bad, Sun Hong did not fall into the well at this time, it is not bad, and said, "We never said that we would get it out in five years." Mr. Jiang said before that it was a little anxious for five years, and at the same time, he did not know the details of this project. ”

In a word, Jiang Chenyang lowered his head in embarrassment.

He was really impulsive before.

"At present, there are already surveying and mapping drawings of the CFM56-3 core machine in China, and we can borrow and borrow that thing. Xie Kai said with a smile.

The crowd was dumbfounded.

When did the things of the US imperialism come into existence in China?

"Really?" Zheng Yucheng didn't believe it.

Xie Kai, this kid is talking nonsense again.

They don't know about the Soviet side, but the US imperialists will never give this thing.

"Absolutely. Over there 606, we can't afford this project anyway, so we have to cooperate, and it's good for them to make a new engine for Project 10, isn't it?" Xie Kai grinned. "They're precious about it. ”

CFM56-3, even if it is a civilian model, it is definitely high-tech, a high-tech blockade for flower growers.

Export technology, that's not to think about.

But China introduced the Boeing-737.

Before the approval of the US Congress and Batumi, some people said, What if the Chinese stole our technology? In addition to those that the Soviet Union aided in building China, and even those industrial projects, China is used to this wild way, stealing technology has become a habit, is it not possible not to steal such advanced things?

In order to prevent Airbus from grabbing fat and meat from McDonnell Douglas, the Boeing team began to lobby, let's sell planes, can't we not sell spare engines? Chinese want to steal technology, and they don't have that ability, right?

Metallurgy, materials, machining, mechanical manufacturing, thermodynamics, aerodynamics, fluid mechanics, cybernetics, etc., what can be done in China?

Didn't you see that they introduced a full set of bass engine technology from John Bull, and now more than ten years have passed, and they have not succeeded?

What's more, this is civilian, can they be made into a military?

As a result, China has the world's most advanced Boeing 737.

The Americans put the spare engine in the box, put a seal on it, and then check it every six months.

As a result, China has a turbofan engine for the CFM56-3 core engine.

Then, on this basis, according to the design, China made the turbofan-10.

This kind of brain hole made the US imperialists dumbfounded.

After all, the military and the civilian have different emphases and different technologies.

For example, for civilian use, our safety comes first, and economy cannot be ignored.

Military use, as long as the performance is sufficient, the cost is high, and the danger is a little more acceptable.

"606 isn't very easy to talk to, we are robbing them of their jobs. Sun Hong smiled bitterly, feeling that Xie Kai was taking it for granted.

Zheng Yucheng said, "It's okay, let's go over there tomorrow and take a look, if we don't give it, we'll find a way." ”

"Let's do our own mapping? Isn't that a waste? And that batch of engines had to be inspected every six months. Sun Hong had to admire Zheng Yucheng's flexible mind.

"......" Xie Kai was speechless.

People have already done it, what else are you doing?

It's a big deal, just get it from 606, don't want to be cheated and cheated, let them choose.

Otherwise, they will all be poached.

"You've been ranked as the least popular with 606. At this time, Jiang Chenyang was embarrassed and said to Zheng Yucheng and Xie Kai. "It's on their blacklist. ”

The crowd was immediately happy.

Zheng Yucheng is digging people everywhere in the country, and everyone knows that they are abducted and deceived.

Many units complained to the above, but in the end, they were comforted by Long Yaohua and others, scolded Zheng Yucheng and others, and then, it was over.

When I got here, the atmosphere was a lot better.

With Jiang Chenyang as the project leader, the teams of each core part have to start discussing, which they can do on their own, which projects need to set up new laboratories, and who is responsible for them, all of which must be considered.

"By the way, the engine has to take full authority digital control system, hydraulic-analogy to you and the control system from the handling performance, can not meet our high thrust engine. Xie Kai thought of this when Jiang Chenyang and others were discussing the need to build those new laboratories.

These things in China are still blank.

Even the turbofan-10, at the very beginning, used a hydraulic-analogue control system disassembled and transplanted from the AL-31 engine, and the problem was not discovered until the J-11 was installed with this thing for flight tests.

At that time, 606 began to develop a full-authority digital control system.

"A full-authority digital control system? Jiang Chenyang wanted to cry without tears.

Xie Kai wants to play a play.

The entire new engine project, almost all of which had to be studied from scratch.

"It's not that it's not difficult, it's that it's desperately difficult. The wrinkles on Sun Hong's face were huddled together and he looked at Zheng Yucheng.

Zheng Yucheng, as the person in charge, doesn't he care?

It's not something that can be done just by saying it, it costs money, and it's a lot of money!

"It's not a big problem, the super seven project, the overall control is in the study of the four-redundant control system, once the research is successful, in the digital control system, the difficulty is much smaller. Zheng Yucheng said.

He didn't know what to do.

Xie Kai said that if he wants to do it, he must do it.

The whole meeting lasted from the evening until half past nine the next morning.

Everyone's eyes were bloodshot, and Xie Kai was even more haggard. He and Zheng Yucheng had only slept for more than an hour the day before.

By now, he was extremely sleepy, and Xie Kai wanted to go to sleep, but he still couldn't.

Following Sun Hong, who also didn't sleep all night, Liao Dongfeng and others inspected the entire engine factory, from the design room to the physical and chemical laboratory, to the high-temperature and high-pressure powder metallurgy workshop, to the machining workshop, the heat treatment workshop, etc.

All the workshops have a commonality, a lot of experimental equipment, at least more than ten years of history.

The number of newly introduced equipment is not large.

CNC machining centers and other high-end processing equipment, almost invisible, only some CNC lathes, that thing, simply can not process high-precision turbofan blades.

"These devices are a bit rudimentary. Xie Kai sighed.

Simplicity means that you have to spend money on new projects.

"The equipment on our side is not as good as Qin Fei, and most of the production lines over there are imported from the UK. ”

"The proportion of CNC machining must be increased as soon as possible. The research work of the four-axis machining center should be almost over, right?" Xie Kai asked Zheng Yucheng.

Zheng Yucheng looked at Xie Kai with a dissatisfied face, this kid came up by destroying the CNC machining workshop, his proposal to start the CNC system, but he didn't know the development progress of CNC machine tools.

"Our research on CNC machine tools is not very comprehensive, but we are cooperating with other machinery factories. After all, we are only developing CNC systems. Zheng Yucheng said.

The CNC system is only one component of the CNC machine.

The control system, on the surface, is only used for civilian CNC machine tools, in fact, many control technologies are related to the control system of tanks and even fighters.

Base 404 has always been less interested in civilian goods.

Especially the leaders represented by Zheng Yucheng, they hardly paid much attention to the progress of the civilian project.

"The technical foundation here really needs to be upgraded. After Xie Kai came out, he said to Zheng Yucheng, "Only the physical and chemical laboratory and powder metallurgy workshop are better." The processing is old-fashioned equipment, not to mention low efficiency, but also prone to quality problems and high scrap rate. ”

"We have to ask for money! There are more than 2,000 people in this factory now, and if we want to upgrade the entire technical base, 200 million yuan is not enough. And that's not even counting the R&D investment in engines. Zheng Yucheng had some flesh pain. "Our money ......"

"Money is a small thing. Xie Kai's heart was also painful, but he didn't show it at all on the surface.

If he told Zheng Yucheng that investing in engines is just a matching, it is estimated that two billion may not be able to come out, and with Zheng Yucheng's character, he will definitely immediately throw out the engine project with the entire engine factory.

"Directly change the itinerary to the Northeast?" Zheng Yucheng asked Xie Kai. "Anyway, you kid got the money. If it's not enough, you will contribute the profits of your game console factory, one or two hundred million dollars a year, and it will make people blush when you look at it, I really don't know why you are not afraid of people's worries. ”

"There are a lot of people who are richer. Besides, did I use any of the money myself?" Xie Kai rolled his eyes, "If we don't go to the Northeast, do you think that with the people of Dongfeng Power Plant, we can get their technical drawings for secretly surveying and mapping?"

The 606 Institute is the earliest aero-engine plant in China, and it was one of the 156 industrial projects aided by the Soviet Union's big brother to China.

In the early sixties, the MiG-21 was successfully copied, and China's turbojet engine also had the advanced level of twin-rotor axial flow turbojet. But until now, the technology of the MiG-23 exchanged from Egypt has not been fully understood, and the turbojet-14 has not yet been successfully studied.

They keep an eye on these things.

It is definitely not easy for 404 to engage in technology.

"I can't get it. The people over there are all brainless, but now that we go, we are probably being watched and guarded. Zheng Yucheng was a little helpless, "Do you have a way?"

"If they don't cooperate, let's just get their technology and cheat them whatever they choose. Xie Kai had a sinister smile on his face.
