Chapter 1021 Let China participate in the Trent 900 project?

Before leaving, Eleanor specifically asked if he could take the brochure with him.

In fact, due to the tight schedule and insufficient printing quantity, Dassault and Snecma previously stated that, in principle, they would not distribute promotional materials to exhibitors on site.

Otherwise, in the end, even our own people might lose everything.

If there is a real need, you can leave your contact information and the publicity department will send you an electronic version.

Or you can send the paper version from Paris later.

However, it is well known.

In principle, it is not possible, which is equivalent to saying that it is possible in practice.

Therefore, Liu Yongquan nodded.

He does not think that the SeA650, a new engine model that has not yet been installed for its first flight, will attract many customers at this air show.

But Rolls-Royce's interest in several specific technologies is real.

Even if the other party cooperates with China through Xiluo Company, they will definitely choose the Gaofa Group, which is close to the water, as their cooperation partner, and will not directly benefit Shengjing.

However, Liu Yongquan's position has improved significantly as he has been working on projects with Chang Haonan over the years.

What about Shengjing and Haojing? Aren’t they all brother units of the same group?

Besides, Liu Yongquan knew the contents of the manual by heart, so he wouldn't lose anything even if he gave it away...

It was not until they saw Eleanor off and returned to the air-conditioned room backstage that Vesta said belatedly:

"Liu... I think there's something wrong with Roger Eleanor just now."

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

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

"He's British...it's normal for you to feel something is wrong with him."

It's generally not wrong to slander Britain in front of the French.

Sure enough, Vesta nodded immediately, and then continued to analyze:

"You're right... But what I meant was that I felt like he might not just have the two identities that he appears to have."

But Liu Yongquan was not prepared to continue dwelling on this topic.

After all, strictly speaking, he had just been colluding with the British under the noses of the French.

It would not be a good idea to ask Vesta to figure this out.

"It does not matter……"

He shook his head:

"No matter who he is, since he showed up at the air show, he could be our potential customer..."

"Besides, even if he had some other purpose, in the end he just took a piece of propaganda from us that would be released to the world soon. The only loss was that we both had to waste a lot of time talking..."

"And to be honest, compared to the SeA650 which has not yet made its maiden flight, I think you should consider how to cooperate with Dassault to fully utilize the performance of the M88-3..."

"..."

After a long speech, Vesta's attention was finally diverted to other places.

……

On the other hand, Professor Elino went around 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 were still some gains.

Therefore, after leaving the exhibition site, he returned to the hotel where the delegation was staying as quickly as possible.

At this time, the rest of Luo Luo's group were gathered in a suite, still feeling upset about their recent failure.

But I couldn't think of any way to redeem it.

Then, suddenly the doorbell rang.

After opening the door, I saw Eleanor, dressed casually, walking in.

Luke Norris, as the person who had the most dealings with the other party, was the first to realize what had happened.

"Professor, do you have any results?"

"of course."

Eleanor looked radiant. He walked straight to an empty sofa and sat down. Then he crossed his legs and began to point and talk:

"Actually, I could have handled this kind of thing by myself, but you had to bring so many people here, especially wearing the same suits, as if you were afraid that others wouldn't know that these twenty-something people were together..."

"We didn't intend to engage in any espionage activities. We just wanted to learn some propaganda content in advance. Your actions have complicated the situation..."

"..."

As the main contributor to this action, Eleanor spent about five minutes criticizing the behavior of creating difficulties even when there are none.

Although the others were not completely convinced, after all, this time someone else had cleaned up their mess, so they had no choice but to swallow their pride...

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

"The first thing that concerns all of us is the combustion chamber outlet temperature..."

He said, flipping open the notebook in his hand.

When the others heard the key words, they also regained their spirits.

"According to the latest information provided by Snecma, their active cooling design is indeed similar to the new air film holes that Dr. Lapworth previously developed for the Trent 900 engine. However, for the sake of safety, it is still up to the doctor to make his own judgment."

Eleanor turned the brochure to the pages related to the turbine part, then handed it to Norris next to him, indicating that everyone should take turns to read it.

Soon, the booklet came into 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 concept is exactly the same.”

“The fundamental heat transfer method is not changed, but a multi-layer, three-dimensional air film hole design is used, and the convection and conduction effects are used 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, the yield rate of this type of air film hole is frighteningly low when it enters the factory environment... and there are dozens of holes to be drilled on a turbine blade. If one of them fails, it will become waste..."

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

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

There was a hint of surprise in his tone.

But his expression was still calm.

After all, France can be regarded as a "long-established industrial power" in the traditional sense. Although its level in the overall design of aero engines is a bit difficult to describe, it is actually not weak when it comes to processing and production alone.

Even Bodi's mind has been opened up.

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 we will not be outperformed by the GP7200 in terms of fuel consumption..."

"At worst, we can just let the French produce the turbines. Airbus is dominated by them anyway..."

GP7200 is a model created by Engine Alliance with its best efforts.

The 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 for the Airbus A380 is actually a competition between North American and European engines.

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

Logically speaking, airlines would definitely prefer the latter.

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

This is very embarrassing...

What lies before us is obviously a great opportunity to turn the tables.

"I have no 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 have been completed by the French..."

"Ok?"

As soon as he finished speaking, more than twenty eyes turned to 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, was probably completed by the Chinese side..."
