Chapter 1028: The real big contract, things are changing!

Although it is impossible to make a final decision based on just one test on one sample, a good start is undoubtedly good news for everyone here.

At least the concerns about the product being completely substandard can be put aside for the time being.

Even if some minor defects are discovered later, there may still be a chance to remedy them.

After all, of the originally planned three months, with a guaranteed minimum of four months, less than 3 days have passed.

At this efficiency, it is enough for the other side to produce four batches of samples...

"Besides the size, are the processing defects serious?"

Bodie took two steps forward and looked at the screen:

"I remember reading a few papers from China before. Their technology route should be laser thermal processing. The morphology of the air film hole surface..."

The influence of Chang Haonan's Nature article that year was quite huge.

As the saying goes, if you want to deceive others, you must first deceive yourself.

After his paper was published, technicians in China who were researching material processing, especially hot processing of metal materials, flocked to this field and published a number of articles of a certain level in just a few years.

Of course, this cannot be considered a waste of resources.

In scientific research, sometimes we cannot pursue cost-effectiveness.

In most cases, truly valuable results are screened out from a large amount of academic garbage.

Just like the studies above.

Although we were not able to produce another usable engineering equipment until the end, we did dig deep into the properties of various types of metal materials and at least accumulated a lot of meaningful data resources.

And objectively, it does play a very good role in confusing people.

Although some cutting-edge scholars have begun to re-examine the feasibility of continuous laser thermal processing and even questioned its application potential in principle, the current mainstream research direction remains unchanged.

Even senior engineers like Bodi were not immune to this.

"The complete morphology can only be known through destructive testing at the electron microscope. We will probably have to wait for... three or four days."

Dr. Lapworth shook his head and replied:

"However, from the test results here, we can basically infer that there should not be a particularly obvious remelting layer, otherwise the channel shape compliance rate would not be as high as it is now... In addition, due to the same reason, the crystal phase should not show any particularly obvious changes."

"As for the cracks... it's hard to say. Whether it's direct observation or testing of relative density, it's probably too late today..."

Hearing this judgment, Bodi frowned in confusion:

"No remelting layer..."

He picked up a turbine disk from a bracket not far away, held it up in the direction of the fluorescent light and stared at it for a moment.

It was impossible to see any clues with the naked eye, so he quickly shook his head in self-mockery and put it back:

"In fact, two years ago, I thought about how the Chinese were going to solve the problems of the thermal melting effect and alloy structure defects..."

"Later, I talked about the Chinese paper with Professor Martin Bock of the Appleton Laboratory. He also felt that although the theoretical part of it was very sophisticated, it was difficult to actually manufacture equipment that met the requirements given China's current industrial level..."

For Bodi, the Trent 900 is certainly important, but in the final analysis it is just one of the models in a series.

In comparison, he was more concerned about the craftsmanship of the Chinese in processing this kind of air membrane hole.

"That's not what I'm concerned about..."

Lapworth shrugged.

"Those of us who do numerical calculations have been using the computing tools developed by the Chinese for several years..."

What this means is that I've gotten used to it.

But after a short pause, she changed the subject:

"But I heard that China has been importing high-precision control motors and drive motors in recent years. If you are particularly interested, you can ask people in the relevant industry."

"Um……"

In response to this proposal, Bodi hummed noncommittally and did not give a clear response.

In fact, for a moment just now, he wanted to ask Lapworth if he could consider reverse engineering this Chinese technology.

The reason why I didn't ask in the end was that I took into account that all I had at hand were finished parts after processing, and I had never even seen other people's equipment, so the conditions were really not enough.

Secondly,...

Reverse engineering, to put it bluntly, is imitation... or to put it more clearly, it is copying.

This is completely different from the nature of borrowing ideas.

It’s not that Bodi’s moral standards are that high.

Instead, they copied a Chinese technology...

It is indeed a bit difficult to overcome this psychological barrier——

I'm taking you to England, the birthplace of the Industrial Revolution.

Rolls-Royce is one of the world's three largest aero-engine companies.

The Chinese can master this technology, so why can't I?

With this mentality, he finally decided to contact the process department first to see if they could think of a solution from a positive perspective.

At least, it has now been confirmed that laser processing is a path that can be used for mass production.

After all, there are 5 sets of turbines right in front of us.

Although the original electrochemical processing method can also produce qualified products, it has almost been sentenced to death in terms of efficiency.

It's time to switch research focus.

……

Spurred on by extra holidays and free vacations, a group of Britons have displayed very un-British efficiency.

Before the end of August, they not only completed all the testing projects, but also went through a series of administrative procedures and sent more detailed processing requirements to Xiro Company.

Of course, it is equivalent to sending it to Gaofei Group.

"Finally..."

Chang Haonan sat at the head of the conference table, looking at the piles of paper materials being taken out of the cart, with a gratified expression:

"These British guys are finally willing to let go..."

At this time, Ren Bingda just walked in from outside in a hurry.

Although he has been working non-stop these days and can't hide the fatigue on his face, he is still very energetic:

"Boss Chang, we have completed the handover and preliminary sorting of all materials."

He took off his work hat and sat in the first seat on Chang Haonan's left:

"The official order that Rolls-Royce has given us is for the high-pressure and low-pressure turbine parts of the Trent 900. The processing requirements for the film holes are basically the same as those for the previous RB211-524B4, except that the hole arrangement and distribution are somewhat different."

After saying this, he picked up the paper cup next to him and gulped down a few gulps of tea.

“Sure enough, it’s this model… the power of the Airbus A380!”

Chang Haonan slapped the table excitedly.

In fact, when he first guessed that the processing object was the Trent series product, he wondered whether it would be the Trent 900.

However, becoming a Tier 380 supplier for the Airbus A is almost like jumping into the core system of the world's aviation supply chain.

The industrial park in Luzhou mainly undertakes some peripheral businesses, and all products will only be installed on aircraft sold to China.

It is equivalent to self-production and self-sales.

But this time it's different.

All A380s purchased around the world, as long as they are equipped with Rolls-Royce engines, must be installed with parts produced in China.

It is still an irreplaceable core component.

That's the A380...

It's completely different from the small-scale operations like the Rafale or the Falcon business jet.

It's almost too good to be true...

Therefore, because he was worried that everyone would expect it without his permission and break the defense without his permission, Chang Haonan never said it out loud.

But now, it's basically time to open the champagne.

“This is a great opportunity.”

After thinking for a while, he said to Ren Bingda:

"If you Gaofei can do a good job on this deal, you probably won't have to worry about orders for at least the next 20 years..."

"Isn't this you, President Chang..."

Ren Bingda quickly switched to flattery mode:

“I will definitely do it!”

Chang Haonan waved his hand seriously:

"I can only guide you for this part. I can't do it all by myself."

"For processing and manufacturing, even if you are familiar with the process flow, the final implementation still depends on the level of production organization, so you can't relax no matter what..."

"..."

While the two were chatting back and forth, the relevant information and text were also transferred one after another.

The table was piled full.

"I remember... the low-pressure turbine of the Trent 900 should have used a new type of high-temperature resistant titanium alloy."

Chang Haonan took a deep breath and quickly returned to the topic:

"Comrade Bingda, please gather the key members of the project team. Our next major task is to solve the processing technology problem of titanium alloy materials..."
