Chapter 1028 A really big contract, things are changing!


    ?While it’s impossible to make a final decision from just one test on one sample, a good start is certainly exciting news for everyone here.


    At least the worries about completely substandard products 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 since the originally scheduled three months, with a minimum guarantee of four months.


    According to this efficiency, it is enough to produce four batches of samples...


    “Besides the size, are the processing defects serious?”


    ??Podi took two steps forward, leaned over and looked 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..."


    ?The Nature article written by Chang Haonan back then had a huge influence.


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


    ?After his paper was published, technical personnel in China 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 sifted from a large amount of academic garbage.


    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 does play a very good role in confusing——


    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 has not changed anyway.


    ?So much so that even senior engineers like Bodi are not exempt from this practice.


    “The complete morphology needs to be done at the electron microscope for destructive testing before we can know it. It will take about three or four days to wait.”


    Dr. Lapworth shook his head and replied:


    "However, from the test results I can basically infer, there should not be a particularly obvious remelted 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 situation should not be as high as it is now... There will be significant changes.”


    “As for cracks…it’s hard to say. Whether it’s direct observation or relative density detection, it’s probably 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 was naturally impossible to tell any clues with the naked eye, so he quickly shook his head mockingly and put it back:


    “Actually, I had been thinking about how the Chinese people were going to solve the problems of hot melt effect and alloy structure defects two years ago...”


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


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


    In contrast, he is more concerned about the Chinese people''s craftsmanship in processing such air film holes.


    “That’s not my concern anymore…”


    Lapworth shrugged:


    “Those of us who engage in numerical calculations have been using calculation tools developed by the Chinese for several years…”


    The implication is that I 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 related industry.”


    "Um…"


    In response to this proposal, Bodi gave a noncommittal hum and did not make a clear response.


    In fact, for a moment, he wanted to ask Lapworth if he could consider reverse engineering China''s technology.


    The reason why I didn’t say anything in the end was because I only had the finished parts after processing on hand, 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... and to put it more clearly, it is copying.


    ?This is completely different from the nature of borrowing ideas.


    It’s not that Bodie’s moral level is very high.


    Instead of imitating a Chinese technology...


    It’s true that I can’t overcome this psychological barrier—


    I am here with you, the birthplace of the industrial revolution.


    I am Luo Luo, one of the top three aviation giants in the world. China can understand this technology, so 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 5 sets of turbines right in front of you.


    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 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 outside in a hurry.


    Although I can’t hide the exhaustion on my face after running around 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 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.


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


    ?Chang Haonan slapped the table excitedly.


    In fact, when he first speculated that the processing target was Trent series products, he 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 entering 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.


    Equivalent to self-produced and sold.


    But this time is different.


    As long as the A380 purchased around the world is equipped with a Rolls-Royce engine, it 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 spoke out because he was worried that everyone would expect to break the defense without permission.


    But now, it’s almost time to open the champagne.


    “This is a great 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:


    “I’ll definitely do it well!”


    Chang Haonan waved his hand seriously:


    “I can only take you this part, I can’t do it myself all the time.”


    “When it comes to 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.


    A table full of people was piled up.


    “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 and gather the key comrades of the project team. Our next main task is to overcome the processing technology problem of titanium alloy materials...”
