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 have said before that in principle they will not distribute promotional materials to exhibitors on site.

Otherwise, you may lose everything in your 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, it is well known.

In principle, if it is not possible, it is equivalent to actually being able to do it.

Therefore, Liu Yongquan nodded.

He does not think that a new model engine like the SeA650, which has not yet been installed on the aircraft for its first flight, can win many customers at this air show.

But Luo Luo's interest in several specific technologies is real.

Although even if the other party cooperates with Huaxia through Xiro 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 standing has improved a lot as he has been working on projects with Chang Haonan over the years -

Why are Shengjing and Haojing not all brothers 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 there's something wrong with that Roger Elinor just now."

Liu Yongquan rolled his eyes slightly and thought to himself, why haven't you come to your senses yet...

However, on the surface, he still agreed with the other party’s statement:

"Being 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 his analysis:

"You are right...but what I just meant is that I feel that he may not only have the two identities on the surface."

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 take a step back, even if he had any additional purpose, in the end he just took away a promotional material from our hands that will be released to the world in the near future. The only loss is nothing more than the two of us. It took a lot of words..."

"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 people were 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, do you have any results there?"

"certainly."

Eleanor was radiant. He went straight to an empty sofa and sat down. Then he crossed his legs and started pointing:

"Actually, I can handle this kind of thing myself, but you have to bring in so many people, especially wearing the same suit, for fear that others won't know that these twenty-some people are together..."

"Originally, we didn't want to engage in any espionage activities. We just wanted to understand some propaganda content in advance. However, after you did this, the situation became 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 were not completely convinced, after all, someone else had wiped their butts this time, so they had no choice but to do it...

Fortunately, after the professor vented his anger, he returned to the topic:

"The first thing we all care about is the combustion chamber outlet temperature..."

He said, opening the notebook in his 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 that Dr. Lapworth previously developed for the Trent 900 engine. However, to be on the safe side, it is up to the doctor to make his own judgment. "

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 book was in Lapworth's hands.

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."

"Instead of changing the fundamental heat transfer method, it uses a multi-layer, three-dimensional air film hole channel design, and uses convection and conduction effects 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 air film hole is frighteningly low... And there are dozens of holes on a turbine blade, and if there is a problem, it will become a waste product..."

Tim Bodie, who had not yet read the contents of the booklet, frowned slightly:

"In other words, the French have solved the manufacturing process of this air film hole and can achieve industrial mass production?"

There was a little surprise in his tone.

But his expression was still calm.

After all, France is also a "old industrial power" in the traditional sense. Although its level in the field of overall aeroengine design is a bit difficult to describe, if it is only about processing and production, it is actually not weak.

Even Bodi's mind was already open.

Without waiting for Eleanor to answer, he immediately proposed:

"If this is true, then we can completely restore the original design of the Trent 900 and raise the temperature before the turbine, so that the GP7200 will not take advantage of the fuel consumption..."

"At worst, we can just let the French produce the turbine part, since Airbus is also dominated by them..."

GP7200, a model created by the Engine Alliance with its signature skills.

This company itself may not be particularly famous.

But its two parent companies are General Electric and Pratt & Whitney.

Two of the three major aircraft engine suppliers.

In other words, the engine selection of the Airbus A380 is actually a North American vs. European competition.

Originally, the trump card of the GP7200 was quietness, while the advantage of the Trent 900 was fuel efficiency.

Logically speaking, airlines would definitely prefer the latter.

However, after realizing that the turbine part designed at the beginning was difficult to put into mass production, Rolls-Royce had to choose to use the traditional air film cooling solution and reduce the temperature before the turbine accordingly.

This is very embarrassing...

And what is in front of us is obviously a great opportunity to turn the tables.

"I don't have any objection to this idea... Of course, the Trent 900 model does not belong to me."

At this point, Eleanor showed a half-smile:

"But... the production of this air film hole may not be completed by the French..."

"Huh?"

As soon as the voice fell, more than 20 eyes looked at him almost at the same time.

"If my speculation is correct, then the turbine of the SeA650 engine... at least the processing of the turbine air film hole, I am afraid it was completed by the Chinese side..."
