Chapter 1021 Let China participate in the Trent 900 project?


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


    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, it’s not possible, which means it’s actually possible.


    Therefore, Liu Yongquan nodded.


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


    However, Rollo''s interest in several specific technologies is real.


    Even if 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 standing has improved a lot as he has been working on projects with Chang Haonan over the years—


    Why Shengjing Haojing, aren’t they all brother 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 out...


    ?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:


    “As a British person...it’s normal for you to feel that 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 piece of propaganda from us 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 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 some 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 resentful 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.


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


    “Professor, have you got any results there?”


    "certainly."


    Elinor was radiant. He went straight to an empty sofa and sat down. Then he 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 20 or so people are together..." 　　　 "Originally, we didn''t want to We are engaging in espionage activities. We 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 combustion chamber outlet temperature...”


    He said, opening the notebook in his hand.


    When other people 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 holes previously developed by Dr. Lapworth for the Trent 900 engine. However, to be on the safe side, it is up to the doctor to make his or her own judgment. "


    ?Eleanor turned the brochure to the pages related to the turbine part, then handed it to Norris next to him, motioning for everyone to take turns to read it.


    Soon, the book 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 ideas are exactly the same.”


    “Without changing the fundamental heat transfer method, we use a multi-layer, three-dimensional air film pore design, and simultaneously utilize 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 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 the manufacturing process of this air film hole and can achieve industrial mass production?”


    There was a little surprise in his tone.


    ?However, his expression is 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 actually not weak when it comes to processing and production alone.


    Even, Bodi’s mind has been opened up.


    Without waiting for Elinor to reply, he immediately suggested:


    “If this is the case, then we can completely restore the original design of the Trent 900 and increase the temperature in front of the turbine, so that the GP7200 will not take advantage of the fuel consumption..."


    “At worst, we can just leave the turbine production to the French. Airbus is also dominated by them anyway…”


    ?GP7200, a model built by Engine Alliance Company with special skills.


    This company itself may not be particularly famous.


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


    The second 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 definitely prefer the latter.


    However, after realizing that the turbine part originally designed 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 is 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 doesn’t belong to me either.”


    Speaking of this, Elinor showed a half-smiling expression:


    “However...the production of this air film hole may not have been completed by the French..."


    "Um?"


    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, I am afraid it was completed by the Chinese side..."
