Chapter 1028 A Truly Big Contract, Things Are Changing!

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

At least the worry about the product being completely unqualified can be put aside for the time being.

Even if some minor defects are found later, there may be a chance to remedy it.

After all, less than 40 days have passed in the original three months, with a guaranteed four months.

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

"In addition to the size, especially are the processing defects serious?"

Bodi took two steps forward and looked at the screen:

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

Chang Haonan's Nature article that year had a huge influence.

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

After his paper was sent out, technicians in China who studied material processing, especially metal material thermal processing, flocked to this direction, and published a number of articles of a certain level in just a few years.

Of course, this is not a waste of resources.

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

In most cases, the truly valuable results are also selected from a large amount of academic garbage.

Just like the above studies.

Although we did not come up with another usable engineering equipment until the end, we did dig deep into the characteristics of various metal materials and at least accumulated a lot of meaningful data resources.

And objectively, it did play a good role in confusing people -

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

So much so that even senior engineers like Bodi are not immune.

"The complete morphology needs to be tested by electron microscope for destructive testing, and it will probably take another... three or four days."

Dr. Lapworth shook his head and replied:

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

"As for cracks... it's hard to say, whether it's direct observation or relative density detection, it should be too late today..."

Hearing this judgment, Bodi frowned in confusion:

"There is no remelting layer..."

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

It is 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 hot melt effect and alloy structure defects..."

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

For Bodi, the Trent 900 is certainly important, but after all, it is just one of the series models.

In contrast, he is more concerned about the Chinese craftsmanship in processing this kind of air film hole.

"That's not my concern..."

Lapworth shrugged:

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

The implication is that we have become accustomed 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."

"Hmm..."

For this proposal, Bodi hummed without comment, and did not make a clear response.

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

The reason why he didn't speak in the end was that he only had finished parts after processing, and he had never seen other people's equipment, so the conditions were really not enough.

Secondly,...

Reverse engineering, to put it bluntly, is imitation... 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 level is so high.

But imitating a Chinese technology...

It's really hard to overcome this psychological barrier-

I'm England, the birthplace of the Industrial Revolution.

I'm Rolls-Royce, one of the three giants of the world's aerospace engines.

Why can't I use the technology that China can figure out?

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

At least, it is now certain that laser processing can achieve mass production.

After all, the five turbines are 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 the focus of research.

…

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

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

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

"Finally..."

Chang Haonan sat at the head of the conference table, looking at the piles of paper materials being moved out of the cart, showing a pleased expression:

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

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

Even though I can’t hide the fatigue on my face due to the hard work these days, I am still very energetic:

"Mr. Chang, we have completed the handover and preliminary arrangement of all materials."

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

"The official order given to us by Rolls-Royce is for the high-pressure and low-pressure turbine parts of the Trent 900. The processing requirements for the air film holes are basically the same as the previous RB211-524B4, but there are certain differences in the arrangement and distribution of the holes."

After finishing speaking, he picked up the paper cup next to him and took a few sips of tea.

"Sure enough, it is this model...the power of Airbus A380!"

Chang Haonan slapped the table excitedly.

In fact, when he first speculated that the processing target was Trent series products, he had thought about whether it would be Trent 900.

However, becoming a second-tier supplier of Airbus A380 in one step is almost equivalent to 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-produced and sold.

But this time it's different.

A380s bought around the world, as long as they are equipped with Rolls-Royce engines, must be equipped with parts produced by China.

It is still an irreplaceable core component.

That's the A380...

It's completely different from small things like Rafale or Falcon business jets.

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

Therefore, Chang Haonan never said anything out of fear that everyone would expect to break the defense without authorization.

But now, it’s basically time to pop the champagne.

"This is a great opportunity."

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

"If you, Haofei, can do this business well, you probably won't have to worry about order issues for at least the next 20 years..."

"Isn't this Mr. Chang..."

Ren Bingda quickly switched to flattering mode:

"It will definitely be done well!"

Chang Haonan waved his hand seriously:

"I can only guide you for this period. I can't do it myself all the time."

"In processing and manufacturing, even if the process is familiar, the final implementation still depends on the level of production organization, so we can't relax no matter what..."

"..."

While the two of them were chatting back and forth, the transfer of relevant information and texts was also completed one after another.

There was a table full of them.

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

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

"Comrade Bingda, go gather the key comrades of the project team. Our next main task is to overcome the processing technology problem of titanium alloy materials..."
