The military-industrial scientific research system of the academic master.

Facts soon verified Chang Haonan's guess.

Just three days later, Ren Bingda, deputy general manager of Gaofa Group, went to Beijing in person to report to the group's leadership.

It means that Xiluo Company has sent a formal letter asking whether it can process the complex structure air film holes on the turbine component of an aircraft engine on its behalf.

He also brought the original letter of inquiry and the minutes of the talks with 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 that is particularly noteworthy.

It's not really a surprise.

Both parties keep a copy of the meeting minutes.

China certainly doesn't care, but the British side may not be willing to put some important content on paper.

After the other two asked a few non-technical questions, Chang Haonan finally got the chance and asked:

"Manager Ren, did the other party mention any specific technical features of this aircraft engine turbine assembly?"

While speaking, he slightly adjusted the position of his chair to avoid making the scene too similar to a trial by three judges.

“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 being unfamiliar with the turbine structure because it was very similar to a model we were producing..."

This somewhat enigmatic description made the three people on the opposite side look at each other in bewilderment.

When it comes to models that are currently being produced by the Gaofa Group and are related to Rolls-Royce, the first thing that comes to mind is of course the WS-9.

However, the British had long since given up on the entire Spey series in terms of aero engines, and it was impossible for them to come up with a new product that required cooperation with China.

The only ones left are WP8, M250, and D436.

The first two are also outrageous no matter how you think about it, so...

"Three rotors..."

Chang Haonan quickly captured the key words.

In Rolls-Royce's current product line, the two main turboprop engines are actually products of the Allison company acquired in the early years. They use a single rotor + free turbine, which can also be said to be a kind of dual-rotor design.

The only authentic British three-rotor engine is...

Trent series.

When this answer popped up in his mind, even Chang Haonan, who had experienced many ups and downs, couldn't help but hold his breathing for a moment.

This is not a small-time effort like M88 or SeA650.

Among the entire Trent series of engines, the smallest one is the Trent 28.5, which has a thrust of "only" 600 tons.

但因为麦道MD-11、波音747-400X和波音767-400ER先后告吹，导致其成为了罗罗公司少有的，因为没了装机对象而导致航发项目取消的型号。

China Aviation Industry Limited Time Experience Card belongs to.

Among the other models still under development, the smallest Trent 700 model has a thrust of 31 tons...

31 tons!

In his previous life, until Chang Haonan was reborn, although China had already produced the fourth-generation engine WS-15, there was still no model that reached this thrust level.

It can be said that the Trent series of engines is one of the cornerstones of the aviation industry in Europe and even the world.

And now, an opportunity to participate in it is before me.

"I think we should not make a decision so quickly..."

Lin Zuoming just said at this time:

"The other party has only given ambiguous conditions and refused to give detailed technical parameters and specific processing requirements for the parts to be processed. I am worried that this is a trap set for us... What if, like what we encountered with the shipbuilding industry before, the Zhuoer Group, they want to collect our liquidated damages?"

As a leader who has worked on the aviation front for decades and has dealt with the West a lot, he is indeed very vigilant.

Zhu Linyu was apparently also somewhat persuaded:

"That's true...So Comrade Zuo Ming, what you mean is that we should not..."

"Mr. Zhu, it's okay."

At the critical moment, Chang Haonan couldn't care less and quickly interrupted the other party.

Zhu Linyu and Lin Zuoming looked at him at the same time.

"what do you mean……"

"The risks that Mr. Lin mentioned do exist, so it's best for us to get in touch with Xiluo more deeply... In fact, it's best to contact the Rolls-Royce Group directly."

Chang Haonan first made a smooth transition, but then changed the subject:

"My opinion is that even if there are risks, as long as they are within the controllable range, we should continue this cooperation!"

“The British asked us to do air film hole processing because they saw the technology applied to SeA650 and it has been put into mass production. Although the process parameters of ultra-short laser processing for different substrate materials may be completely different, this time... I will personally take the lead in the project!”

Hearing this statement, Ren Bingda almost jumped up from his chair——

The last aero-engine project that General Chang personally led was the WS-10.

The significance of this model itself is self-evident.

Even if they were just some scraps in the process of making the WS-10, they helped their Gaofei Group solve the long-standing problem of localizing the Spey MK202.

Not only did they solve the problem, but they also developed an upgraded model with better performance.

To this day, the WS-9A remains the most important bread and butter of the Haofa Group.

He couldn't even imagine how much benefit Mr. Chang would bring if he took action again.

Zhu Linyu was also stunned:

"Comrade Haonan, I don't mean to question your ability, but one person can't handle everything. You already have a lot of projects on hand. If you personally lead another person who is far away in Gaojing..."

"Don't worry, Mr. Zhu. I can arrange it."

Chang Haonan replied:

"If it really doesn't work, you can consider postponing other work for a period of time and give priority to this cooperation project!"

"This……"

Even Ren Bingda was greatly surprised at this moment.

As for the other two, there is no need to mention them.

“If we succeed in cooperating with Rolls-Royce, it will indeed improve our status and reputation in the international aero-engine field to a certain extent, but the other party will definitely not publicize our work, nor will it allow us to fully participate in the entire aero-engine research and development…”

Lin Zuoming asked doubtfully:

"Boss Chang, is it really such a high priority?"

Chang Haonan waved his hand:

"Participating in overall research and development is indeed a bit too fantastical... at least it is not possible now."

"But a new type of high-temperature resistant titanium-aluminum alloy is used on some of the turbines of the Trent series engines, which is a blank in my country's current aviation material research... and since the other party wants us to process the product, even if it is pure OEM, we must provide information about the turbine substrate and coating."

Having said that, he clenched his fist and knocked on the table:

"Even if this information may not be complete, it is still very critical technical intelligence for us!"
