This kind of cross-border cooperation, especially such an extraordinary mode of cooperation, naturally cannot be finalized in a day or two.

However, the intentions of both sides are really strong, and the parts of the good parts are almost completely complementary, so there is nothing worth wasting too long.

Especially for Eurocopter, since this cooperation is an exchange, it will not even involve money, and there is no need to worry about being audited to be a communist party (although they do have a common party).

It's like tailor-made for them, so to speak.

Therefore, in less than a month, the details of the cooperation between Bingfei Group and Eurocopter to carry out the NH90/Zhi-12 project were notified to Chang Haonan.

It also means that his plan has basically succeeded more than half of it.

Next, just let Liu Hongbo do a targeted calibration in the transmission system, especially the gearbox, and then wait for the Europeans to find the problem.

No matter what Eurocopter Group says, it is also a giant in the helicopter industry with a name and surname, so that it will not even be able to understand the cause of the accident.

Moreover, when that time comes, Chang Haonan will definitely help them.

When he received the news, he was in his chief designer's office, looking at the experimental data submitted in front of him, and adjusting the model of the single crystal solidification process.

Several core personnel involved in the turbofan 10 project were also there, and naturally they also saw the content of the document.

After all, the news of foreign cooperation is not something that needs to be kept secret.

No very Haonan knew earlier, and someone would come to inform him, and if others wanted to know, they would have to ask themselves.

"Mr. Chang, Bingfei's cooperation method is ...... It's wonderful......"

He Ming flipped a few pages of documents to the end, and the whole person's feeling can be said to be enlightened:

"Just by modifying such an inconspicuous operation in the name of the article, we can circumvent many regulations against us, which is a blessing for foreign companies that want to cooperate with us but have difficulty in operation!"

"The person who came up with the idea was an absolute genius......"

As he spoke, he smacked his lips unsatisfactorily.

Obviously, He Ming didn't know that the genius he was talking about was right in front of his eyes.

Haiyide, who was sitting on the other side, understood more about the situation, and smiled directly when he heard He Ming's emotion:

"Mr. He, the person who came up with the idea is sitting here with us......"

As he spoke, he pointed to Chang Haonan, who was sitting first, with a pen.

"Ah......h

"This ......"

The conference room was filled with a cheerful air for a while.

"Well, I also got some inspiration from foreign experience before, and I came up with a solution."

Chang Haonan raised his head, waved his hand at the other people and said.

This is not an excuse, but a real reference to other collaborative projects.

It's just a project for the future.

Italy's Alenia Macchi M346 trainer aircraft and Russia's Yak-130 trainer aircraft are products in this isomeric form.

The core design of the two is almost identical, but there are slight differences in the final performance due to some factors at the level of subsystem performance and customer requirements.

Although everyone knows that the M346 is actually a technical solution provided by Yakovlev, and the Yak-130 has received financial support from Italy, both sides claim that it was developed independently and has nothing to do with the other.

What cooperation?

It's been divorced a long time ago!

As a result, the M346 can normally enter service with the air forces of NATO countries.

In fact, according to the current point in time, this project should be almost at the end of the cooperation between the two parties.

After a pause, Chang Haonan followed up with another sentence:

"And, after all, this is still a way to passively circumvent restrictions, and in a few years, we should make them dare not restrict us at all!"

"As long as you can get actual benefits, these nominal things can be put aside for a while."

He Ming, who recovered from the embarrassment from his childhood, also quickly changed the topic:

"I just don't know when we will be able to let foreigners take the initiative to ask us for cooperation......

After receiving a huge order for more than 100 aircraft from the Persian side, all of which were twin-engine aircraft transformation and upgrading, the Dawn Factory has intuitively felt why arms exports are called profiteering industries.

Although the transaction between the two countries was carried out in the form of barter, i.e., Persia paid Huaxia for crude oil instead of dollars, but Huaxia Petroleum Company, which received the oil, made internal payments based on the transfer price.

Although this price is still a lot lower than the international oil price, the Dawn Factory was still in a dilemma of not even being able to pay wages a few years ago.

If you can directly work with Europeans to earn dollars......

He Ming felt excited when he thought about it.

"When we finish the project at hand, it is estimated that it will be soon......"

Chang Haonan looked at the computer in front of him that was in the process of calculation, stretched and said.

If ordinary people say such a sentence, it is estimated that everyone will only take it as an encouragement or slogan.

But the person who spoke this time was Chang Haonan......

Then we have to pay attention to it.

As a result, the enthusiasm for work in the entire conference room suddenly increased a lot......

……

More than half a month later.

Maybe it's because I was inspired by the cake painted by Chang Haonan, or maybe it's just good luck.

In short, the progress of constructing the model of the single crystal directional solidification process is much faster than expected.

In the precision casting center, Chang Haonan, dressed in blue tooling, stood in front of the specially improved directional solidification furnace and explained the key points of the entire production process to the equipment operators who were about to be responsible for the trial production task.

"The first process of single crystal blade preparation is the formation of crystal nuclei, but turbine blades have high requirements for single crystal integrity, so we cannot use the traditional seed implantation method, but use a crystal selector to screen in naturally growing columnar crystal seeds."

"The crystal selector used in the production of turbofan 10 blades is designed on this drawing, and the cylindrical wafer generated in the initial section is eliminated by the crystal selection section of the circular section spiral, and finally only one can enter the casting, and only the temperature of the initial section can be controlled in this part......

"The process of making molds is no different from the past, and you should be very experienced......

"The most important thing is the last solidification part, the temperature of the hot end, that is, the water cooling jacket of the crystallization table is controlled at 25 °C, the temperature of the upper preheating zone is controlled at 1515±1 °C, the temperature of the lower preheating zone is controlled at 1550±1 °C, and the pumping speed is between 4-4.5mm/min......"

"In addition, in the solidification process, it should be noted that the expansion coefficient of the ceramic core and the shell are different, and it is easy to have eccentricity or core leakage after the high-temperature cooling cycle, resulting in dimensional deviation or even complete crystallization failure, so it is necessary to fix the ...... before production."

“……”

Such detailed process parameters, as well as the precautions in the production process, made the audience a little surprised while relaxing.

After all, this can be said to be the first industrial production of nickel-based superalloy material single crystal blades in the whole of China, but the operation requirements they have just written down are almost like a mature operation manual.

Even if he had heard some of the deeds of the young chief master in front of him, he still had some doubts.

This is also human nature.

After all, the people who were selected to participate in the trial production task were all experienced technicians.

But being experienced, in another way, also means that they are more susceptible to past knowledge.

Of course, everyone is an old comrade in the military-industrial system, and accidents are accidents, and it is impossible for anyone not to jump out and question the authority of the chief division without a long eye.

The name Chang Haonan, at least in the aviation industry system, can still be convincing.

With Ma Liping's order, all the operators quickly returned to their workstations and started the preparation tasks before production step by step.

"Mr. Chang, I have prepared two sets of personnel and equipment this time, which can achieve seamless connection between each round of production testing without delaying any time......

Ma Liping's words made Chang Haonan stunned for a moment, and immediately realized that the other party thought that he might need to try a few more times to succeed, so he made extra preparations.

How to say it.

The idea is good.

It's just that there is a high probability that it will not be used.

"What ...... this?"

The latter thought about it for a while, and felt that it seemed a bit against science to say that 100% guaranteed success, so he still took a little bit:

"Director Ma's preparations are indeed in place, but I probably have ...... Ninety and a half percent certainty, can be a successful production! ”
