The military-industrial scientific research system of the academic master.

At this time, Chang Haonan, who had just replied to Perelman's email, naturally did not know that these emails exchanged between the two of them would leave a mark in the entire history of human mathematics, even because the time was close to 1999. On December 12st, it was dubbed the “New Millennium Mail” by the bad guys.

In fact, according to his work efficiency, the reply letter should have been sent earlier.

The main reason why Perelman waited so long in despair was because, by coincidence, the day after he received the email from the other party, a French team consisting mainly of Snecma and Dassault appeared. The defense industry delegation flew to China.

The purpose is, of course, to concretely implement the cooperative research and development of the M88 engine after reaching a certain consensus in the preliminary negotiations.

As the chief planner of the Aerospace Power Group and perhaps one of the most experienced people in China in exporting technology to foreign countries, Chang Haonan naturally became the person in charge of this matter.

Of course, his presence is definitely not required in the negotiations.

At least not at first.

This can also be regarded as a little negotiation trick——

It is best to let the team's second-in-command come forward to preside over the negotiations. This way, the standards are high enough, and if you really encounter any problems, you can also delay it by saying "it needs to be reported for instructions."

And if the person who can make the final decision is present, it will lead to a lack of buffering in the situation.

But not attending does not mean not paying attention.

Remote control is more troublesome.

……

Qin Province, Haojing.

Since the negotiation in 1997, this place has almost become a window for China’s foreign cooperation in the aviation field, especially cooperation with the European Union.

Perhaps it is because the joint venture with Boeing did achieve a win-win situation, so even Europeans have some inexplicable affection for Hao Jing.

Several times when I went to China for meetings or negotiations, I always asked by name to set up the venue here.

Finmeccanica and Airbus even set up their offices in China in Haojing.

It was a surprise that an inland city that was not originally open to a high level was allowed to start systematic foreign-related business.

And this time is no exception.

Although Dassault's military aircraft department and Snecma Group have not had much communication with China in the past ten years, they have still learned from the experience of their peers.

Aviation hotel.

In fact, it was the location where the negotiations took place.

Later it was acquired by Haofei Group and renamed.

About twenty people entered the conference room on the top floor one after another and sat down on both sides of the long conference table.

But no one spoke immediately.

There was an eerie silence in the room.

Their eyes collided fiercely in mid-air.

The atmosphere was tense to the extreme.

Although the two sides reached an agreement on "cooperation", when it came time to dig into the details, since it was a sensitive military-related project after all, there were still many differences.

The most critical one——

China believes that since you want us to help solve the problem, it should be a reasonable request to transport an M88 engine to us first, right?

But the French side's reaction was that you are not kidding me. If you transport the engine to China, and then send it to a high-altitude platform for testing, wouldn't you know everything?

What's the difference between this and letting us run naked in front of you?

They believe that the cooperation model between Bingcheng Aircraft Industry Group and Eurocopter should be followed, with China sending technical personnel to France to participate in the project. They also said that money is not an issue, and all Chinese technical personnel will receive business travel subsidies in accordance with French standards.

We said that this is to solve the problem for you, and you should have paid the labor fee. The reason why Icefly and Eurocopter cooperate in France is because the two parties are each other's suppliers at the legal level, and in turn Eurocopter Group We also sent people to guide the development of the Z-12 helicopter, which is completely incomparable with the M88 situation...

In short, the two sides just went back and forth like this, doing oral gymnastics all morning, but there was no progress.

The afternoon negotiations began in this atmosphere.

But what was different from the morning was that this time, Liu Yongquan, the on-site person in charge of the Chinese side, had an extra notebook in front of him.

A notebook full of notes.

Finally, after a slightly awkward opening remarks, the afternoon session officially began.

The focus of the dispute between the two parties, as well as their respective attitudes, seemed to be no different from that in the morning.

Until Liu Yongquan opened his mouth.

The first sentence made the Frenchman on the opposite side almost break the defense.

"Actually, your concern about leaking technical secrets is completely unreasonable, because we actually now have a general understanding of the situation of the M88 engine and the problems it faces, so there is nothing to leak."

The people in Snecma opposite were stunned after hearing this sentence, and for a moment they didn't know how to respond.

Liu Yongquan didn't give them a chance to respond.

He opened the book on the table.

That was given to him by Chang Haonan before the negotiation.

"Brilliant tips."

The contents inside...

To be honest, Liu Yongquan himself didn't dare to believe it.

That's why I didn't take it out in the morning.

But seeing the negotiations reaching a deadlock, he had no choice but to consider taking drastic measures.

"Let me give you an example."

He stared into the eyes of Ian Vista, a senior engineer from the Snecma Group opposite:

"Is the M88 engine prone to combustion chamber flameout when running at low speeds in moderate rain or above, eventually leading to engine shutdown?"

Vista's whole body trembled, obviously subconsciously wanting to answer, but then he realized that this was on the negotiation table, so he stopped moving.

However, Liu Yongquan could clearly see that the other party was just about to nod.

This feedback gave him strong confidence.

So, he continued:

"In addition, when the fan speed is maintained at around 85% for a long time, the first-stage fan will have a high probability of entering resonance, causing damage to the blade structure and even the inner wall of the engine's outer casing."

"besides……"

"..."

Every time Liu Yongquan said something, the faces of Vesta and the opponent's general manager, Charles Edsteiner, turned pale.

And because they were originally white, when the former closed the book and raised his head again, there was no color on their faces...

"Finally, there is one more thing."

Liu Yongquan closed the notebook again:

"After the engine is overhauled for the first time, after another 1000-1500 cycles, extended cracks will be found on the surface of the turbine disk, but the original cycle life of this component should be much longer."

"You probably haven't discovered this problem yet, but it does exist. If you don't believe it, you can test it after returning to China..."

The whole place fell silent again.

But this time, there was no more eye contact.

Obviously, this wave just caused a lot of psychological damage to the opponent.

"us……"

Ed Steiner's voice was trembling as he spoke:

"We want to apply for an adjournment..."

Liu Yongquan showed a kind smile, nodded, and signaled to the other party to please.
