As for why the large-diameter turbofan engine manufactured by MTU is made of solid titanium alloy blades, people say, "Rolls-Royce's RB710 engine and GM's CF-34 engine are also designed in this way." This made Yang Hui only silently note down this problem, and let the researchers crack these deeper reasons after returning to the second institute.

"There is another problem, we should now officially give this engine a number, now we call it 'large bypass than small thrust civilian turbofan engine' is definitely not good, we are about to participate in the bidding, we are a little behind in naming this point."

Rouse has thought of this question for a long time, but has never had the opportunity to raise it, and until now Southwest Science and Technology has not proposed to discuss the issue of naming the engine, Rouse finally can't wait now, it can't wait to ask.

And the number of this engine, from Yang Hui and even the entire Southwest Science and Industry has not thought about it, in the past, the number of the aero engine of the Republic was given by the military, and it was not the turn of the scientific research unit to worry about it.

This time, Southwest Science and Industry also habitually did not care about this matter, but the problem is that he is not a military engine for this engine development, and this civil aviation engine does not even have national investment, so naturally the number and naming of the matter does not belong to the military.

Now that Rouse asked this question, Yang Hui originally wanted to directly answer "There is an army to number", but fortunately, in the end, Yang Hui remembered the special features of this engine, and it seems that this naming really has nothing to do with the army.

Well, Yang Hui began to get entangled, he really didn't think about numbering. It's a bit tricky to ask this question all of a sudden.

There is no reliable plan to think left and right. We can only look at the MTU plan first: "We don't have any good suggestions, this is our first time in the field of civil aircraft engine development." Southwest Science and Technology did not have a numbered rule before. ”

Southwest Science and Industry has not manufactured civilian turbofans, and similarly, this MTU does not have this kind of experience, and they do not have formal naming rules to follow, and both sides are cute newcomers.

Fortunately, Rouse had thought about it before this, and he still had a plan: "I think it's good to add the English initials of our two countries together, and then number them according to the order in which the engines were developed." Our MTU accounted for a little less in the development of the engine, so it would be better to write it into a CG-1 turbofan engine. ”

Hearing this numbering, there is nothing remarkable about it. But at least it is reasonable, and it is impossible to find fault with it, but Yang Hui always feels that something is missing.

It wasn't until I saw this eye-catching '1' that I understood the problem, the old man Mao Taizu taught us not to be too honest in numbering this kind of thing, and we can't honestly go 12345678 one by one, so that people can see the situation at a glance, and they all know that you are still a novice, which is very bad.

You can't use the number 1. Yang Hui thought left and right after thinking about it and finally offered the banner of take-it-ism, this kind of problem is easy to handle, directly borrowing from the numbering scheme of Dassault Phantom 2000, the reason why Dassault skipped Phantom 4 and went directly to Phantom 2000. That's because Dassault shouted that this is a fighter for use after 2000.

In this way, Yang Hui had an idea: "CG is very good at the beginning, but the number 1 is not very good. We are a turbofan engine for the year 2000 and should be numbered CG-2000. That's good. ”

CG-2000, as Rouse kept muttering the codename. I feel more and more that this number is good.

"Well, I also think this number is very good, both nice and smooth, the meaning is also very good, it seems that as long as we work together to name this number, presumably our CG-2000 engine can also be successfully developed under our cooperation, and achieve the victory of the CFM-56 engine."

The two sides smiled and walked to the other side, after looking at the finished fan just now, and then looked at other components developed by MTU, such as the engine fan case, low-pressure turbine, etc., all of which looked quite decent.

"It seems that not only our Southwest Science and Industry is working hard for this engine project, MTU company has also paid a lot for it, we have reason to believe that this engine will have a very good future, and our cooperation between the two sides is also full of brightness."

Speaking of which, Yang Hui began to play a big trick on the Germans again. But Rouse is also the president of a world-class multinational company, and he has never seen any wind and rain, although this kind of flickering technique is very powerful, but it has not had much effect on Rouse.

Instead, it allowed Rouse to seize the opportunity and tentatively ask: "A brighter future?" I don't know if we can continue to deepen the cooperation between the two companies, but MTU is also interested in the emerging market of the Republic. ”

Hearing the words of MTU, Yang Hui very wisely chose to play haha to avoid the past, now is not the time to talk about these issues at this critical moment, in case the two sides are unhappy because of some other problems, it will be more than worth the loss.

Yang Hui could only say some ambiguous replies at this time: "If the cooperation between our two sides can satisfy both of us, naturally Southwest Science and Industry has no reason to refuse, after all, who will not get along with money." Right? ”

Yang Hui's words are very meaningful, the reason why money is put in an important position, this is to tell MTU that Southwest Science and Industry is also a profit-oriented company, and the kind of cooperation that sacrifices the interests of Southwest Science and Industry is definitely impossible.

If Rouse is not stupid and can understand Yang Hui's words with the normal thinking of the leader of an international Fortune 500 company, I believe that many questions that he wanted to ask but did not ask could be answered.

Both partners have looked at the technology developed by the other and are satisfied, so there is no need to have too many other ideas at this point, just quietly wait for the last moment to come.

In Chang'an, the ancient imperial capital where it is rare to see foreign people, it is extremely rare for hundreds of foreigners to appear in a guest house at one time. Some of the knowledgeable staff could clearly tell from the accents of these foreigners that they were from three places: authentic American English, pure British English, and hard German.

Three languages means that there are three teams here, and the day after the three teams arrive at the West Flying Guest House, the itinerary of the West Flight is in the hands of the three teams.

First of all, the three parties who intend to provide MPC-75 aircraft engines are required to report their engine development progress to Xifei, and secondly, they are required to submit various data of the engine and the finished parts that can be taken out for review.

At this time, although Xifei did not have the experience of hosting this kind of international large-scale bidding meeting, it also had partners from Germany, and the MBB company was also rich in experience, and the cooperation between the two sides was enough to determine the most important engine bidding meeting for this aircraft.

It is normal for Xifei to need these materials, but the development progress of the three engines does not seem to be satisfactory, and Yang Hui initially expected that the development progress of the engines of the other two parties was far from leaving him aside.

Yang Hui personally sent these materials to the Xifei and MBB joint assessment team, gave a general introduction, and then left the assessment team, and walked outside with some trepidation, not knowing what the final situation would be.

When he walked outside, Yang Hui suddenly saw a familiar face, this person seemed to have seen it somewhere (to be continued. )
