Chapter 1028 The real big contract, the situation is changing!
Although it is impossible to make a final decision through just one test on one sample, a good start is undoubtedly exciting news for everyone here.
At least the worries about the product being completely substandard can be put aside for the time being.
Even if some minor flaws are discovered later, there may not be no chance of remedying them.
After all, less than 40 days have passed out of the original three months, with a minimum guarantee of four months.
According to this efficiency, it is enough to produce four batches of samples from the opposite side...
"Apart from the size, especially the processing defects, are they serious?"
Bodi took two steps forward and leaned over to face them. He glanced at the screen twice:
"I remember reading several papers from China before. Their technical route should be laser thermal processing, and the surface morphology of the air film holes..."
Chang Haonan’s Nature article had a huge influence.
As the saying goes, if you want to deceive others, you must first deceive yourself.
After his paper was published, Chinese domestic technicians studying material processing, especially thermal processing of metal materials, flocked to this direction. In just a few years, many articles with a certain level of quality were published. .
Of course, this cannot be called a waste of resources.
In scientific research, sometimes we cannot pursue cost-effectiveness.
In most cases, those truly valuable results are screened out from a large amount of academic garbage.
Just like the studies above.
Although we were unable to produce another usable engineering equipment until the end, we still explored the characteristics of various types of metal materials and at least accumulated a lot of meaningful data resources.
And objectively, it has indeed played a very confusing role -
Although some cutting-edge scholars have begun to re-examine the feasibility of the continuous laser thermal processing route, and even from In principle, its application potential is questioned, but in any case, the current mainstream research direction remains unchanged.
Even senior engineers like Bodi are not immune to this.
"The complete morphology needs to be done at the electron microscope for destructive testing before we can know it. It will probably take another...three or four days."
Dr. Lapworth shook his head and replied:< br>
“However, from my test results, it can be basically inferred that there should not be a particularly obvious remelted layer, otherwise the compliance rate of the channel shape cannot be as high as it is now... In addition, due to the same reason, There should be no particularly obvious changes in the crystal phase. "
"As for cracks...it's hard to say. Whether it's direct observation or relative density detection, it's probably too late today..."< br>
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.
Of course it is impossible to see any clues with the naked eye, so he quickly shook his head mockingly and put it back:
"Actually, I was thinking about it two years ago. However, how are the Chinese 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 feels that although the theoretical part is very sophisticated, with China’s current industrial level, it is difficult to actually manufacture equipment that meets the requirements..."
For Bodie, the Trent 900 is important, but in the end it is just one model in a series.
In contrast, he is more concerned about the Chinese people's craftsmanship in processing such air film holes.
"This is not my concern..."
Lapworth shrugged:
"Those of us who engage in numerical calculations have been engaged in numerical calculations since several years ago. Just use the computing tools developed by the Chinese..."
The implication is that I have become accustomed to it.
But after a 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 someone in the relevant industry."
"Hmm..."
In response to this proposal, Bodi gave a noncommittal hum and did not do it. Give a clear response.
In fact, for a moment, he wanted to ask Lapworth if he could consider reverse engineering this Chinese technology.
The reason why I didn’t say anything in the end was because I only had the finished parts on hand after processing, and I had never even seen other people’s equipment, so the conditions were really not enough.
The second thing is...
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.
Not that Bodie's moral standards were that high.
But to imitate a Chinese technology...
It is indeed a bit difficult to overcome this psychological barrier -
I bring Ying, the birthplace of the industrial revolution.
I am Luo Luo, one of the top three aviation giants in the world. China can understand the technology, why can't I do it?
With this mentality, he finally decided to go to the process department first to see if he could think of a solution from a positive perspective.
At least, it is now certain that mass production can be achieved through laser processing.
After all, there are five sets of turbines right in front of you.
Although the original electrochemical processing method can 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 holidays and free holidays, a group of British people showed a very un-British efficiency.
Before the end of August, they not only completed all testing 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 stacks 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 the outside in a hurry.
Although I can’t hide the exhaustion on my face due to the constant rotation 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 hat and sat in the first seat on the left hand side of Chang Haonan:
"The formal 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 those of 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.
“It is indeed 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.
It’s just that 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 is mainly Undertake some peripheral business, and all products will only be installed on aircraft sold to China.
It is equivalent to self-production and self-marketing.
But this time it's different.
As long as the A380s purchased around the world are equipped with Rolls-Royce engines, they must be equipped with parts produced by China.
It is still an irreplaceable core component.
That's the A380...
It's completely different from the Rafale or Falcon business jets.
It was too good to be true...
So, because he was worried that everyone would expect to break the defense without authorization, Chang Haonan never said anything.
But now, it’s almost time to open the champagne.
“This is an excellent opportunity.”
After thinking for a moment, 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:
“We can definitely do it well!”
Chang Haonan waved his hand seriously:
"I can only take you this step, I can't do it myself all the time."
"Processing and manufacturing this thing, even if the process is familiar, the implementation in the end still depends on the level of production organization, so it cannot be done in any case Relax..."
"..."
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 people.
"I remember... the new high-temperature resistant titanium alloy should be used in the low-pressure turbine of the Trent 900."
Chang Haonan took a deep breath and quickly returned to the topic:
"Bing Comrade Da, go and gather the key comrades of the project team. Our next main task is to overcome the processing technology problem of titanium alloy materials..."
