While walking and talking, the three of them had already arrived in Haiyide's director's office.

"No, no, Mr. Hai, there's no need to be in such a hurry."

Looking at Hai Yide, who was almost impatient, Chang Haonan instead stopped his plan to hold a meeting in advance:

"After all, it is a national cooperation, and the scale of the technical meeting of all the backbone members is too large, so you can prepare more, and let the comrades from other units familiarize themselves with the environment and work mode of the 606 side, so that it is better to carry out follow-up work, sharpen knives and not chop wood."

When Haiyide heard this, he immediately stopped turning around, and then his eyes lit up:

"What Mr. Chang means...... Let the comrades of other fraternal units also ......"

And he could hear the off-string sound of Chang Haonan's words.

That is, the other party is ready to take this opportunity to re-integrate the entire aviation power industry in China in a bottom-up manner.

The first step, of course, is a matter of some details.

Chang Haonan nodded:

"No way, since you want to participate in the same project, you must first unify the working methods, since the Taihang project is led by the 606 Institute and the 410 factory, then the relevant practices must naturally be implemented in accordance with our existing methods."

The 606 institute is generally referred to as the National Development Power Institute in the industry, and there is no need to bring the word Shengjing at all, because in the earliest aviation industry planning, it is actually the only aero engine research institute in the country.

Although a series of events such as the third-line project later led to the blooming of the aviation development plant, the status of the 606 Institute has never been shaken.

However, it has not been shaken, and after thirty or forty years, there have been quite huge differences in some specific business methods-

Although with the release and implementation of a series of new national military standard documents, Huaxia's aviation industry has gradually begun to form its own set of standardization system, but the standard is only the most basic thing after all.

Under the same set of national standards, the habits and styles formed by design and manufacturing units that have worked independently for a long time will still be very different.

The most typical example is the Sukhoi and MiG, which are also Soviet (Russian) design bureaus.

At the beginning of the No. 11 project, the 601 and 112 factories, which were already accustomed to MiG aircraft, found that they were different in the design and production materials of the Su-27 when they were confronted with the design and production materials of the Su-27.

Fortunately, Sukhoi's status in cooperation is not so high today, so the technical documents provided are much better in terms of completeness and accuracy than in previous lives, so that the project progress has not been delayed too much.

Boeing, which just acquired McDonnell Douglas across the ocean, is facing similar trouble.

At least in terms of the aviation industry, Huaxia is not a country with deep pockets and strong technical background like the United States and the Soviet Union, so it still has to give priority to concentrating forces, unifying working methods, and reducing internal friction.

"Okay, then I'll let the comrades in the institute take them to familiarize themselves with the situation in the next two days."

As the director of the 606 Institute, Haiyide was naturally quite excited to hear this kind of thing, although this would not bring him any direct benefits, but at least the long face was certain.

"There's no rush for this, there's one more thing."

Chang Haonan hurriedly stopped the other party again.

First, such a large project is not bad for half a day, and secondly, he wants to determine first, what stage the turbofan 10 will be in in 1997:

"Turbofan 10 from the project to the present ten years, in addition to the project pre-research, there should also be some basic design data, before the official start of work, I want to see what the current situation is."

Since you want to grasp the general design plan, you must know it in your heart.

In the previous life, because the whole project was pushed back many times, the research and development work of the turbofan 10, especially before 2005, was quite confusing, and Chang Haonan was not an expert in the history of the development of the aviation industry, so even if he reopened it once, he still could not find any effective information from memory.

I had to go through the first-hand information.

"What ...... this?"

Hearing Chang Haonan's request, Haiyide hesitated.

The project of Taihang is indeed special, and it has been in a state of approval for a long time, but it has not been approved.

It stands to reason that the pre-research work should be completed before the formal establishment of the project, but because there is almost no technical foundation, the project that has been approved is actually engaged in pre-research eighty percent of the time.

The remaining two percent of the time is to engage in a few hands-on designs, but the results are naturally not very optimistic.

Haiyide has been responsible for the management of Kunlun engines before, so it is normal that he is not familiar with this aspect.

"I have to call Comrade Liu Yongquan, he is the deputy chief designer of the Taihang project, and he has presided over the completion of several preliminary design plans so far."

Haiyide said as he picked up the phone from the table next to him.

After a brief communication, he put down the earpiece and looked at Chang Haonan again:

"Let's go to the conference room next to it, it's still not very convenient here."

"I won't follow, there are still a lot of things to do in the project of aviation to gas turbine, the 701 Institute is a little anxious during this time, saying that the navy suddenly put forward some requirements for the anti-submarine performance of the frigate, so now the gas turbine program has a high probability of winning in the end, but we need to provide a prototype with a complete version of the performance as soon as possible."

Yan Zhongzhong said as he put on the coat he had just taken off and prepared to leave.

"Mr. Yan won't follow to participate in the Taihang project?"

Haiyide asked half-jokingly while sorting out the documents on the desktop.

"If it weren't for Comrade Xiao Chang, I might indeed have exerted my spare energy."

Yan Zhongzhong, who had already walked to the door, waved his hand:

"Now that I have such a capable next generation, it just so happens that my old bones are a little unbearable, so let's do some projects that are not so high......

After saying that, he quickly disappeared around the corner outside the door.

"Alas...... That's what Lao Yan said, but their gas turbine design room isn't lit up all night long......"

Haiyide shook his head, and then handed an envelope and two separate pieces of paper to Chang Haonan in his hand:

"Your official appointment document, but the original, but we have to keep it on file, I will give you an extra copy, take it away and keep it as a souvenir."

"I don't think there will be a younger model chief engineer in the foreseeable future......"

……

Soon, Liu Yongquan and several other key members responsible for the design of the subsystem in the Taihang engine project came to the conference room next to it.

Compared with the previous paper documents and archives of the Turbojet 14 and J-8C on box counting, the Turbofan 10 is much lighter in terms of posture because the progress itself is very slow, and a lot of technical data has been electronic.

Liu Yongquan quickly opened the laptop he carried with him and spent more than ten minutes opening a series of engineering files.

It's all blueprints.

However, most of them are cross-sectional drawings drawn in CAD.

Only the front fan and the rear nozzle have been 3D modeled, but they are still rough.

After all, the entire Taihang project team didn't have much manpower before, and it was normal.

"I'm not afraid of Mr. Chang's jokes, we did have a few preliminary design plans before, but the completion was relatively poor, this is already the most recent start, and the progress is the best."

Liu Yongquan said and pushed the computer in front of Chang Haonan with some embarrassment:

"The earlier ones, we can't design them ourselves until the back, they are all scrapped cases, and this is also a step that we have stolen from you before, and learned from a lot of mature foreign models."

"It's okay, I'll just take a look."

Chang Haonan was not surprised by this situation, after all, even the turbojet 14 had a lot of traces of patchwork before his overhaul, let alone the turbofan 10.

And he could tell almost immediately what the prototype of this version of the design was.

"3-stage fan, 9-stage compressor, 1-stage high-pressure turbine, two-stage low-pressure turbine...... This is based on the GE9 core machine, right? ”

When he saw this design, Chang Haonan already had a basic understanding of the stage that the turbofan 10 was currently in——

Although the design is more advanced in some details due to the butterfly effect he brings, this version is still a replica of the F110 engine in general.

That is, one of the two powerhouses of the F15 and F16.

Liu Yongquan and several other people looked at each other a few times:

"Mr. Chang's vision is really powerful, which we borrowed from the CFM56-3 engine."

When they were designing, they didn't think about hiding the overall technical source, but Chang Haonan could accurately judge it after just looking at it for a few seconds, which was really not easy.

Haiyide originally thought that Chang Haonan would be disappointed when he saw this plan, but the latter stared at the computer screen for about ten minutes, but nodded with satisfaction:

"It's pretty good to be able to start with CFM56 and design to this extent."

It's not that Chang Haonan comforted a few other people.

Huaxia does not have a ready-made F110 engine on hand for reference.

You must know that CFM56 is actually one of the power of Boeing 737, which is a large bypass ratio turbofan engine, and the difference between the overall design and the small bypass ratio turbofan used in fighters is quite obvious.

Therefore, Liu Yongquan and others actually got the GE9 core machine from CFM56, and made such a design that is extremely close to F110 on the basis of the latter.

It's really good.

"Still."

After giving high praise, Chang Haonan shook his head again, and then changed his words:

"The GE9 core engine and the F110 engine are indeed good things, but they are not suitable for the actual situation of our Huaxia."

At least it doesn't fit into the current timeline, what I'm actually like after I'm reborn—he added in his mind.

In the previous life, the final version of the turbofan 10 was finalized and installed, and it was really derived from the design scheme of this sibling of the F110.

It's just that as Chang Haonan brings more and more changes to this world, and his own ability level (including the system level, of course) is getting higher and higher, many things are no longer good to directly copy the experience of his previous life.

"This ......"

Liu Yongquan, who was still a little excited just now, suddenly became nervous again:

"So this plan ......"

"Of course, it's not completely worthless, some details are still remarkable, and they can even be used."

Chang Haonan stretched out his arm and pulled out a stack of papers from the desktop next to Hai Yide:

"But in general, most of the content must still be torn down and reinvented, at least, we must come up with a core machine that really suits us."
