The Military-industrial Scientific Research System of the Academic Master Chapter 779

Chapter 779: First, let China Airlines lose its reputation.

In terms of technology, as long as Chang Haonan speaks, it is basically the final word.

However, for the newly established Aerospace Power Group, external cooperation, especially in the form of technology export, is still a new thing.

Although Chang Haonan has promoted projects such as NH90 before, at that time he was only making suggestions, and the comrades of Bingcheng Aircraft Industry Group were actually responsible for implementation.

As for the other people…

There is even less experience in this area.

China's ability to engage in reciprocal technological exchanges with Europe started with the M60. It has taken less than four years to now, and there are only a few signature projects.

So, everyone still thinks about it a lot.

“Comrade Haonan, when our group was established, didn't we set three key development directions?”

Deng Shiyou said:

“After the end of Turbofan 10, the original plan was to shift the focus to the pre-research and project establishment work of those three models. If an international cooperation project is suddenly added, will it affect our originally planned timetable?”

The M88 happened to be a model that was forced to dance with shackles due to lack of design experience.

“It's just that Snecma has been focusing on single-rotor engines in the past, and now it suddenly makes a dual-rotor model. It lacks experience and has created such a mess. If it is just improved to a usable state, it will not be too difficult.”

"Exactly, we have always said that the Turbofan 10 is a major training for our group. After the training is over, there will always be several assessments or exercises before the next actual combat. For the M88 project, it can Think of it as a big test to see how good our technical staff are! ”

Furthermore, CFM56 itself also has some common problems.

However, after a round of research, I found that using other people's core opportunities to lock up the ideas and upper limits will not give full play to its advantages in design, and China's production and manufacturing level is still inferior to that of the United States in this era. There is a certain gap, which is equivalent to only being able to create a youth version of the F110 in the end.

This concern is quite reasonable.

The first test model, M88-1, even dared to indicate a thrust of 8.3 tons at sea level (equivalent to a thrust-to-weight ratio of 10). In the end, it was found that the lifespan and reliability exploded at the same time. It must not be installed in mass-produced machines, resulting in the failure of the first few aircraft. The Rafale prototype can only be equipped with the F404 top for a period of time.

At the beginning, the French, who thought they had obtained GE technology, were quite confident.

If you make repairs on the basis of CFM56, it is equivalent to dancing with shackles, it is better to start from scratch.

But the reason why Chang Haonan dared to be so sure was mainly because the early M88 had too many problems. It had the same level as the turbofan 10, and even a slightly higher temperature in front of the turbine, but it could only exchange for 7.5 tons of thrust and The thrust-to-weight ratio of 8.5 is completely hampered by the design.

In fact, before planning to take over the Turbofan 10 project that year, Chang Haonan specifically considered continuing to use the CFM56 core machine and developing a plan with lower risks and difficulties.

It may not be a good thing to have a stall that is too big.

That's why the current “3.75 generation” turbofan 10 is available.

However, after the sudden loss of technology sources, this engine, which was already at the end of its research and development cycle, still encountered a series of problems.

For a newly established enterprise, sometimes there is just a layer of window paper between "bold exploration" and "blind expansion".

The M88-2 currently being tested and planned for installation should increase the temperature in front of the turbine and reduce the thrust to 7.5 tons.

However, Chang Haonan immediately waved his hand:

Of course, if we talk about processing and manufacturing technology alone, even after two years of improvement, China is barely able to compare with old European industrial countries like France.

“I am relatively familiar with CFM56, and I have also learned about the general situation of M88. The potential is actually very high.”

For example, the gap between the high-pressure turbine rear shaft outer ring grate ring and the second grate ring is too large, which can easily cause the grate teeth to crack, and the original steel wire damper cannot inhibit the crack expansion, causing this part to have a negative impact on the work. The environmental tolerance is extremely poor, and seal failure or even breakage may easily occur.

Just a few modifications to these questions are enough to confuse the French.

Of course, if you want to unlock the potential further, that's fine too. means you have to add money.

“There is one more question, Comrade Haonan.”

After a moment of silence, Chief Accountant Wen Kangjian, who had not spoken just now, pushed up his glasses and asked Chang Haonan:

“Is it possible that the French came to us to ask for cooperation this time just to show off to the Americans and use this matter as a bargaining chip to force General Electric to turn around?”

“After all, although there are some conflicts between the United States and France, they are still NATO countries after all. Can they really trust us to directly participate in the research and development of air force main battle equipment?”

Wen Kangjian's words may be something that anyone would have thought of twenty years later, but in 1999, they were still quite insightful.

Several other people also looked at each other and quickly realized that what he said made sense.

“This possibility cannot be ruled out.”

Chang Haonan pondered for a moment and replied:

“In other words, I guess the French are most likely prepared. If the Americans can change their minds, that would be better. If they refuse to look back, they will consider asking us for help.”

“This is using us as weapons...”

Deng Shiyou frowned.

“I think this is not necessarily a bad thing for us.”

Before Chang Haonan could speak, Lin Zuoming unexpectedly expressed his position before him:

“I think everyone is well aware of General Electric's status and reputation in the field of aerospace engines.”

“Even if the cooperation fails in the end, as an emerging force, we can be used by the French as a bargaining chip against General Electric, and we are successful. No matter how you look at it, it is equivalent to advertising for us.”

Lao Lin may not be a technical expert, but he still has some sensitivity in running a business.

“Yes, that's my opinion too.”

Chang Haonan immediately expressed his support:

“At this stage, as long as we can improve our aviation power reputation, we can only make profits but not lose money.”

“Of course, it would be best if the cooperation finally comes to fruition. The whole world will know that we have cleaned up the mess after GE gave up the project..."

Some things can be viewed from different angles and lead to different conclusions.

After Lin Zuoming and Chang Haonan's analysis, everyone suddenly felt that being used as a gunman was not so difficult to accept -

Can I eat with GE at a table, how many people want to be the door without the door ...

Zhu Linyu's eyes swept half a circle in front of him. Seeing that everyone seemed to have no other questions, he opened his mouth and said:

“In this case, I agree that we should actively promote this cooperation with Snecma and Dassault.”

After speaking, he gently raised his right hand to indicate a vote.

　　After all, it is a leadership team meeting. Even if no one expressed opposition just now, the decision-making process still has to go ahead.

Six other people also raised their hands to express their agreement.

“Passed unanimously.”

Zhu Linyu nodded, then lowered his head and made a simple note in his notebook, and then continued:

“Then this will be regarded as the unanimous opinion of our entire group and reported to the Commission of Science, Technology and Industry for National Defense, and then we will prepare to officially start negotiations!”
