Chapter 1021 Let China participate in the Trent 900 project?
Before leaving, Elinor specifically asked if he could take away the brochure in his hand.
In fact, because time is too tight and the printing quantity is insufficient, Dassault and Snecma said before that in principle they would not distribute promotional materials to exhibitors on site.
Otherwise, we may lose everything in our hands in the end.
If you really need it, you can leave your contact information and the publicity department will send an electronic version.
Or you can mail the hard copy from Paris later.
However, as we all know.
No in principle is equivalent to yes in practice.
Therefore, Liu Yongquan nodded.
He does not think that a new model engine like the SeA650, which has not yet been installed on its first flight, can win many customers at this air show.
But Luo Luo's interest in several specific technologies is real.
Although the other party cooperates with Huaxia through Xiluo Company, it will definitely choose Haofa Group, which is close to the water, as the cooperation partner, and it will not directly benefit Shengjing.
However, Liu Yongquan’s position has improved a lot as he has been working on projects with Chang Haonan over the years -
Why Shengjing and Haojing are not all fraternal units of the same group?
Furthermore, Liu Yongquan is very familiar with the contents of the manual, and he will not lose anything even if he gives it away...
It wasn't until after watching Elinor leave and the two of them returned to the air-conditioned room backstage that Vesta said with some hindsight:
"Liu... I think that Roger Elinor just now , something seems wrong.”
Liu Yongquan rolled his eyes slightly, wondering why you haven’t come to your senses yet...
But on the surface, he still agreed with the other party’s statement:
"The British...it's normal for you to feel something is wrong with him."
There is generally nothing wrong with criticizing the British in front of the French.
Sure enough, Vesta nodded immediately, and then continued to analyze:
"You are right... But what I just meant is that I feel that there may be more to him than meets the eye. Those two identities.”
But Liu Yongquan is not prepared to continue to dwell on this topic.
After all, strictly speaking, he was colluding and cooperating with the British under the eyes of the French.
It would not be a good idea if Vesta had to figure this out.
"It's not important..."
He shook his head:
"No matter who he is, since he appears at the air show, he may be our potential Customer..."
"Besides, to put it in perspective, even if he had any additional purpose, in the end he just took away from us a piece of publicity that will be disclosed to the world in the near future. It’s just a product, the only loss is that we both spent a lot of time talking..."
"And to be honest, compared to the SeA650 which has not yet made its first flight, I think you should consider how to cooperate with Dassault to fully utilize the performance of the M88-3..."
"... ”
After a long discussion, Vista’s attention was finally diverted to other places.
......
On the other side, Professor Elinor went around in circles for several days, and finally got the information he wanted.
Although it did not directly help solve the structural strength problem of EJ200 as he expected, there are still gains.
Therefore, after leaving the exhibition site, he returned to the hotel where the delegation stayed as quickly as possible.
At this time, the rest of Luoluo's group was gathering in a suite, feeling brooding about the failure just now.
But I can’t think of any way to save it.
Then, suddenly the doorbell rang.
After opening the door, he saw Eleanor walking in, dressed casually.
As the person who had dealt with the other party the most, Luke Norris was the first to react to what happened.
"Professor, have you got any results there?"
"Of course."
Elinor was radiant and went straight to an empty sofa He sat down in front of him, then crossed his legs and started pointing:
"Actually, I could handle this kind of thing myself, but you had to bring in so many people, especially wearing the same suits, for fear that others wouldn't know that these more than 20 people are together..." "Originally, neither of us. I want to engage in espionage activities. I just want to know some propaganda content in advance. If you do this, the situation will become more complicated..."
"..."
As a major contributor to this operation, Eleanor spent about five minutes fully criticizing this behavior of creating difficulties without difficulty.
Although the rest of the people are not completely convinced, after all, someone else has wiped their butts this time, so they have no choice but to do it...
Fortunately, after the professor vented his anger, he returned to the topic:
"The first thing we are all concerned about is the issue of the combustion chamber outlet temperature..."
He said Open the notebook in your hand.
When others heard the keyword, they cheered up again.
“According to the latest information provided by Snecma, their active cooling design is indeed close to the new air film hole previously developed by Dr. Lapworth for the Trent 900 engine. However, to be on the safe side, it is still Let the doctor judge for himself.”
Elinor turned the brochure to the pages related to the turbine part, then handed it to Norris next to him, gesturing for everyone to take turns to read it.
Soon, the booklet came to Lapworth.
She narrowed her eyes slightly and moved closer to take a closer look.
After a moment, Lapworth nodded:
"Indeed... although the specific parameters may be different, the design ideas are exactly the same."
"Do not change the fundamental heat transfer method, but use a multi-layer, three-dimensional air film hole channel design, and use convection and conduction effects at the same time to form a more effective heat insulation film on the blade surface..."
" But the biggest problem is that although it can be prepared in the laboratory, after entering the factory environment, the yield rate of this kind of air film holes is frighteningly low... And there are dozens of holes punched in a turbine blade, and if there is a problem with one of them, it will Turned into waste..."
Tim Bodie, who had not yet had his turn to read the contents of the brochure, frowned slightly:
"In other words, the French have solved this kind of air film hole. Can the manufacturing process achieve industrial mass production?"
There was a hint of surprise in his tone.
But his expression was quite calm.
After all, France can be regarded as an "old industrial power" in the traditional sense. Although its level in the field of overall aerospace design is a bit hard to describe, it is not weak in terms of processing and production alone.
In fact, Bodi's mind has already opened up.
Not waiting for Elinor to answer, he immediately suggested:
“If this is the case, then we can completely restore the original design of the Trent 900 and reduce the temperature in front of the turbine. Put it up, so that the GP7200 will not take advantage of the fuel consumption..."
"At worst, we can just leave the turbine part to the French for production. Airbus is also led by them anyway..."
GP7200, a model built by Engine Alliance with special skills.
The company itself may not be particularly famous.
But its two parent companies are General Electric and Pratt & Whitney.
Two of the three major aero-engine suppliers.
In other words, the engine selection of the Airbus A380 is actually based on the North American engine versus the European engine.
Originally, the GP7200’s trump card is quietness, while the Trent 900’s advantage is fuel economy.
Logically speaking, airlines must prefer the latter.
However, after realizing that the initially designed turbine part was difficult to put into mass production, Rolls-Royce had no choice but to return to the traditional film cooling solution and reduce the temperature in front of the turbine accordingly.
This is very embarrassing...
What lies before us is obviously an excellent opportunity for a comeback.
"I don't have any objection to this idea... Of course, the model Trent 900 does not belong to me."
Speaking of this, Elinor showed a half-smiling expression:< br>
"But...the production of this air film hole may not have been completed by the French..."
"Huh?"
As soon as he finished speaking, more than twenty eyes looked at him almost at the same time.
"If my guess is correct, then the turbine of the SeA650 engine...at least the processing of the turbine air film hole, is probably completed by the Chinese side..."
