Chapter 1024 High Temperature Resistant Titanium Aluminum Alloy
Facts quickly verified Chang Haonan's conjecture.
Just three days later, Ren Bingda, deputy general manager of Haofa Group, went to Beijing in person to report to the group's leadership.
It means that Xiro Company officially sent a letter asking whether it can process the complex structure of the air film hole on the turbine component of an aerospace engine.
He also brought the original copy of the inquiry letter, as well as the minutes of the meeting with the British representatives George Breen and Adam Whittle.
While Zhu Linyu and Lin Zuoming were asking about the situation, he flipped through it from beginning to end.
There is no information of particular concern.
Not really a surprise.
Each party keeps a copy of the meeting minutes.
Of course it doesn't matter to China, but the British side may not be willing to put some important content on paper.
After the other two asked several non-technical questions, Chang Haonan finally got the chance and asked:
"Manager Ren, has the other party mentioned some specific technical characteristics of this kind of aero-engine turbine assembly?"
While speaking, he also slightly adjusted the position of his seat to avoid making the scene too close to the three-chamber trial.
"Not during the talks."
Ren Bingda shook his head without any hesitation:
"But after the conversation, Whittle mentioned to me that there was no need to worry about not being familiar with the turbine structure because it was very close to a model we were producing..."
This somewhat riddle-like description made the three people on the other side look at each other in confusion.
When it comes to models being produced by Haofa Group that are related to Rolls-Royce, the first thing that comes to mind is of course the Turbofan 9.
However, the British have long given up on the entire Spey series at the aviation development level, and it is impossible to produce a new product that requires cooperation with China.
The only ones left are the Turbojet 8, M250, and D436.
The first two are also outrageous, so...
"Third rotor..."
Chang Haonan quickly captured the key words.
In Rolls-Royce's current product line, the two leading turboprop engines are actually products of Allison acquired in the early years. They use a single rotor + free turbine. Of course, it can also be said to be some kind of dual-rotor design.
And the original British three-rotor is only...
Trent series.
When this answer popped up in his mind, even Chang Haonan, who had experienced strong winds and waves, couldn't help but stop breathing for a moment.
This is not a small game like M88 or SeA650.
Among the entire Trent series of engines, the smallest one is the Trent 600 with a thrust of "only" 28.5 tons.
However, due to the failure of the McDonnell Douglas MD-11, Boeing 747-400X and Boeing 767-400ER, it became one of the rare models of Rolls-Royce that had its aerospace project canceled due to lack of installation targets.
The limited-time experience card of China Aviation Industry belongs to yes.
Among the other models still under development, the smallest Trent 700 sub-model also has a thrust of 31 tons...
31 tons!
In the previous life until Chang Haonan was reborn, although China had built the fourth-generation engine Turbofan 15, it still did not have a model that reached this level of thrust.
It can be said that the Trent series engines are one of the cornerstones of the air transport industry in Europe and even the world.
But now, an opportunity to participate was right in front of him.
"I think it's better not to make a decision so quickly..."
Lin Zuoming happened to say at this time:
"The other party has only given ambiguous conditions and refused to give detailed technical parameters and specific processing requirements of the parts to be processed. I am worried that it is a trap deliberately set for us... What if it is like the shipbuilding industry before? What happened to the Zhuoer Group who wanted to take our liquidated damages? "
As a leader who has worked on the aviation front for decades and has had many dealings with the West, he is indeed very vigilant.
And Zhu Linyu was obviously a little moved:
"That's true...so Comrade Zuo Ming, what you mean is that we won't..."
"Mr. Zhu, it's okay."
At the critical moment, Chang Haonan couldn't care much anymore and quickly interrupted the other party.
Zhu Linyu and Lin Zuoming looked at him at the same time.
"you mean……"
"The risks Mr. Lin mentioned do exist, so we'd better go deeper with Siro... In fact, it's best to contact the Rolls-Royce Group directly."
Chang Haonan made a smooth transition at first, but then changed the subject:
"My opinion is that even if there are risks, as long as they are within control, we will continue this cooperation!"
"The British came to us for air film hole processing because they saw the technology applied to SeA650 and it has already been mass-produced. Although the process parameters of ultra-short laser processing for different base materials may be completely different, this time... …I will take the lead on the project myself!”
Hearing this statement, Ren Bingda almost jumped out of his chair——
The last aviation project that Mr. Chang personally took the lead in was the Turbofan 10.
The significance of this model itself goes without saying.
Even if it was just some scraps from the process of developing the turbofan 10, after picking them up, they helped their Haofei Group solve the long-standing problem of localization of Sibei MK202.
Not only was it solved, but an upgraded model with better performance was also modified by hand.
To this day, Turbofan 9A is still the most important job of Haofa Group.
Now that Mr. Chang takes action again, he can't even imagine how much benefit it will bring.
Zhu Linyu was also stunned:
"Comrade Haonan, I don't mean to question your ability, but after all, one person can't do all the work. You already have a lot of projects on hand. If you personally take care of another one who is far away in Haojing..."
"Don't worry, Mr. Zhu, I can arrange it."
Chang Haonan replied:
"If it doesn't work, you can consider postponing other work for a stage and give priority to this cooperation project!"
"this……"
Even Ren Bingda was greatly surprised at this time.
Not to mention the other two.
“If we successfully cooperate with Rolls-Royce, it will indeed improve our status and visibility in the international aerospace industry to a certain extent, but the other party will certainly not publicize the work we have participated in, and will not allow us to fully participate in it. Throughout the development of aero-engines..."
Lin Zuoming said doubtfully:
"Mr. Chang, is it really such a high priority?"
Chang Haonan waved his hand:
"Participating in overall research and development is indeed a bit too whimsical... at least it is not possible yet."
"However, a new type of high-temperature-resistant titanium-aluminum alloy is used on some turbines of the Trent series engines. This is currently a gap in my country's aviation materials research...and since the other party wants us to process products, even if it is a pure OEM, it must provide Information about turbine substrates, and coatings."
Having said this, he clenched his fists and knocked on the table:
"Even though this information may not be complete, it is still very critical technical intelligence for us!"
