Just on the third day after the project information was submitted, the three parties walked into the small auditorium required by the bidding team again, where several parties could settle down and maximize the normal performance of everyone.

Looking at Luo Luo and GM who had been sitting clearly on the left and right, Southwest Science and Technology and MTU were a little late, Yang Hui could only smile helplessly at Law, and the two walked to the middle of the auditorium and sat down, I'm afraid this will be the focus of the audience later!

It turns out that the situation is indeed as Yang Hui expected, the meeting has not yet started, and the people have not arrived, and both the left and right sides have begun to stare at the Southwest Science and Technology-MTU team in the middle, and it seems that they have steadily pulled the hatred.

Yang Hui, who was sitting in the front row, and Rouse, who was next to him, both felt this tense atmosphere, and the two began to mumble quietly, this was to prepare in advance.

After a good discussion between the two, the MPC-75 engine review team finally came late, along with the familiar faces that Yang Hui saw three days ago, in the team that came to participate in the review, it seems that more people from the West Flying side are coming, Yang Hui's eyes are sharp, and he saw Tang Changhong, an old classmate who is as young as himself.

This guy is the deputy chief engineer of the MPC-75 project, responsible for the design of the entire aircraft wing, and anyone who can lead the team to master supercritical wing technology, regardless of whether he is young or not, is worthy of this deputy chief engineer position.

After all, the role of this supercritical wing is indeed too great, and if this technology is used well, it can also play a good role in fuel saving, which is a technology that is done from the aspect of aircraft design, which is very unusual.

I didn't see the shadow of this guy in the previous review team, and I guess I definitely wasn't a member of the review team. It is more likely that he was attracted because of the particularity of this meeting, and the subsequent arrival of Ma Fengshan, the chief engineer of the MPC-75 project, made Yang Hui affirm that this meeting was very valued by Xifei.

Raise the alert one level again. In your heart, you must calculate whether you have missed anything, and you must do it as foolproof as possible. The current Southwest Science and Industry is different from Rolls-Royce and GM, CG-2000 is the first step for Southwest Science and Industry to begin to move towards civil aviation engines, and this step cannot afford failure.

Yang Hui was sitting in the first row of seats below, it was very conspicuous, and Tang Changhong, who had just walked into the auditorium, also saw Yang Hui when Yang Hui saw him. Tang Changhong has nothing to be jealous of his college dormitory classmates who have gone all the way to the top, and if he is allowed to be the deputy chief teacher, he will not be allowed to be the general manager?

What's more, there was not a single mediocre person in his entire dormitory back then, and he became the deputy chief teacher. Yang Hui became the general manager, Wang Yongqing followed the team to the United States McDonnell Douglas to participate in the J-8 2 project, it is said that even McDonnell Douglas is very satisfied with his ability, as for the only roommate Yang Wei who continued to study in graduate school that year, although he came out to work relatively late, but he also grasped the key technology development of a key model.

At this time, Tang Changhong didn't think too much about Yang Hui, at most, he was a little surprised that Yang Hui personally participated in the bidding for the engine this time.

After everyone was seated, the leader of the judging team sitting on the auditorium stood up and announced the news.

"Today. The reason why everyone has gathered here is to let everyone have a deeper understanding of this project, not only our aircraft developers know about your three engines, but you also know your own engines. It is even more important to adopt this meeting. Let everyone know each other about the other two engines and compare them to find out the advantages and disadvantages of each engine, which will have a big impact on which engine to use later. ”

As soon as he said this, he said. It did not surprise the three parties too much, everyone is a veteran of the international market bidding meeting for many years. It had long been breezy and calm, and when he walked into the auditorium and saw the other two opponents, he guessed the purpose of this meeting.

Not reacting too aggressively is the best-case scenario. MBB showed rich experience at this time, and if it took over the person in charge of Xifei, it would immediately burn the flames of war to the developers of the three engines.

"Everyone has more or less experienced the current situation, so I won't talk about the rules, let's get to the point, or the first to clearly state that the CG-2000 engine developer for the MPC-75 engine provides the engine to talk about the advantages and disadvantages of this engine, and the shortcomings will be made up by the other two parties."

Yang Hui didn't calculate it even after a thousand calculations, because the CG-2000 engine was the earliest, so it had to be pulled out as the first bird in accordance with the first-come, first-served principle, or in front of the two international aero engine giants, which is true

I glanced at Rouse, although this guy was very serious about this meeting, but he was obviously unwilling to stand up and speak, it seems that this is because Southwest Science and Industry accounts for a relatively large proportion of the entire CG-2000 engine project, and it also caused MTU to shrink at this time.

Seeing this situation, the troops couldn't just be silent, Yang Hui could only stand up and sell melons.

"Okay, since we have taken out the CG-2000 engine and recommended it to the MPC-75 regional airliner, this is naturally because we have a strong confidence in this engine, and our confidence comes from the excellent performance of this engine."

After having a beginning, Yang Hui seems to have a draft for a long time, to talk about the advantages of the CG-2000 engine, that is, it can not be finished for three days and three nights, rich language and highly infectious body movements always make people can't help but stop and listen carefully to Yang Hui's explanation.

"The best and most important thing about this engine is the gear transmission system it uses, which can make the fan and the low-pressure turbine work at different speeds, so that they can be more adapted to the tasks they need to complete, to achieve the effect of a three-rotor engine design, and the ultimate goal is to make this engine more fuel-efficient, after our calculations and evaluations, this technology can save up to 15% of the engine."

Of course, at this time, the 15% fuel saving advertised is naturally the data under laboratory conditions, and it will definitely not be able to reach this indicator in actual use, but this is not a problem, anyway, everyone is playing like this, if you really want to be more serious, then look at the data in the laboratory, anyway, I have a basis for this.

Although the words are said so, Yang Hui is so unscrupulous in front of the other two companies to brag about how good his engine is, how can this be annoying, since ancient times, there is no first, no second, and it is this kind of 'class to get an axe'.

Before he finished speaking, he was about to say a few more innocuous shortcomings and so on modestly, and Luo Luo on the other side couldn't sit still, as if he was sitting on a chair and suddenly the chrysanthemum was bursting.

'Pong' stood up suddenly, and the bloodshot expression on his face showed that Luo Luo was very excited now, and he couldn't stand Yang Hui's excessive boasting, where did the usual modesty of the Oriental people go?

"For this gear transmission technology, we Rolls-Royce company has also studied, the results show that this technology can not be as fuel-efficient and reliable as the RB211 three-rotor design, the most important reduction gear system in the gear transmission turbofan engine has been a world problem, and now the world can only be used in one or two tons of turbofan engines, I do not think that Southwest Science and Industry plus MTU will have the ability to solve it. This is a kind of flashy and beautiful trapping, and the development of this engine is destined to be unsuccessful. ”

It's certainly not enough to say that the technology is flashy, and as a company that relies on technology, Rolls-Royce has its own way of proving its point.

"The wear and tear of the reduction gear is a problem for a long time and high-speed operation, the wear after high-speed rotation leads to the increase of the gap between the teeth, which not only makes the transmission ratio inaccurate and ultimately leads to the loss of power, at the same time, the noise of the engine will also increase with the increase of the gap between the teeth, how do you solve these problems?"
