Chapter 1026 The production efficiency that Luo Luo can’t understand...
?When Chang Haonan saw this sample trial production contract in the conference room of Haofa Group, he immediately laughed out loud...
“Uh...Mr. Chang?”
?Ren Bingda is still a little unclear.
"nothing."
Chang Haonan was wearing a blue overalls that he had not worn for a while. He shook his head with a hint of ridicule:
“RB211-524B4…The British are really careful…”
??As he spoke, he flicked a piece of information on the table and explained to the other party:
“This model is a Boeing 747-200, and it has the same power as the L1011-200. It’s almost 20 years old and will be phased out soon... How could there be any special-shaped air film holes that we need to process?”
“To put it bluntly, we still don’t trust our level, and we are worried that useful technical information will be taken away by empty-handed white wolves... so we first throw out a less advanced old guy to explore the way.”
After clarifying the words, Ren Bingda naturally understood it instantly, and quickly came over and asked:
“Then let’s…”
“To remain unchanged in response to all changes.”
Chang Haonan didn’t wait for him to finish the question before he answered directly:
"No matter what, the British are Party A...actually they are Party A''s Party A, and it is also the first time they have such in-depth cooperation with us. It is normal to be a little suspicious..."
“In addition, the RB211 engine is relatively conservative in the use of materials. According to the information provided by Rolls-Royce, although it is different from our specific brand, the turbine part is still mainly made of nickel-based alloy, so..."
While the two of them were talking, slightly chaotic footsteps came from the corridor outside.
Soon, a group of about fifteen or sixteen people appeared at the door of the conference room.
"Report!"
A technician wearing the same work clothes as Chang Haonan said loudly.
“Come in.”
Chang Haonan had no choice but to temporarily suspend the topic, motioned for everyone to take their seats in order, and then opened the technical information in front of him, preparing to introduce the key technical aspects of this sample production.
?However, when he raised his head again, he accidentally caught a glimpse of a somewhat familiar face among the crowd.
Chang Haonan searched in his mind and quickly found a matching name:
“Are you...Comrade Zhang Zhenhua?”
?Zhang Zhenhua, the director of the technical department before 430 Factory was completely restructured into Haofei Group.
?? He was also one of the representatives sent by Factory 430 to Shengjing to learn from the experience when Chang Haonan launched the precision engineering plan based on the turbojet 14 project.
He later also participated in the Turbofan 10 project and played an important role in the verification of some technologies.
However, as the Turbofan 9A, which was the Turbofan 10 technology verification model, began testing, Zhang Zhenhua had to leave the project team and return to his original unit to take charge of the work.
Since then, the two have not seen each other again.
It’s been almost four years since we were separated.
?Zhang Zhenhua, who was still in his prime at that time, had already turned gray at the temples.
Considering the age of the other party, the simple passage of time may not be enough to bring about such a huge change.
Apparently, he is also worried about the Haofa Group...
“Mr. Chang.”
Zhang Zhenhua, who was directly called by his name by Chang Haonan, stood up and shook hands with the former with some evasive eyes:
“I’m really ashamed…”
?The expression on his face was a little gloomy:
“After so many years, now we have an opportunity in front of our Haofa Group, but we still have to trouble Mr. Chang to take charge of the project personally...”
?After so many years, Zhang Zhenhua’s title is still the director of the technical department of Haofa Group.
The pace of progress has indeed failed to keep up.
Of course, this is also related to the actual situation of Haofa Group.
Whipfan 9 is a digestion and absorption technology, D436 is directly introduced into the final assembly, and NK32 is not easy to understand in a short time.
The self-developed turbofan 20 is still in the project preparation stage...
In short, compared to the big brother next door, the results are indeed not very impressive.
“What’s this…”
Chang Haonan smiled immediately after hearing this and said with relief:
“Ultra-short laser processing is, after all, a technology developed under my leadership. It is your first time to come into contact with it, and it is normal for you to be unfamiliar and uncomfortable with it.”
“In Shengjing, it was only after I took them through the process that some people gradually began to be able to take the lead..."
"And from another perspective, the idea of ??using ultra-short lasers to replace continuous lasers can be concealed for a while. If the technology itself is really that simple and can be completely familiar to you in a year or two, then how can other countries Can’t we catch up soon?”
?This angle is indeed relatively fresh and refined, so that Zhang Zhenhua, who was a little depressed just now, was stunned for a while after listening to it.
?Then I think it does make some sense...
“Okay, let’s get to the point.”
We are all adults, and we can only rely on ourselves to adjust our mentality. Therefore, Chang Haonan did not say any more, but stood up directly and came to the back of the small podium:
“I think comrades should already know the general situation, so I won’t go into details. In short, the turbine part of RB211-524B4 is still mainly made of nickel-based alloy, so the database we built before can be directly used.”
?He said that he turned on the computer, and a PPT page appeared on the screen:
“Of course, the specific parameters of the British base materials are quite different from ours, so we still need to use the blanks provided by them to conduct several rounds of experiments..."
…”
For Chang Haonan, this process is basically familiar.
?Although the workload is not low, there are sufficient manpower after all, and there are also several experienced veterans from the 606 Institute.
The only problem is the equipment.
Haojing Institute of Optical Mechanics has currently produced a total of four sets of ultra-short laser processing equipment including prototypes.
?Two sets of mass-produced models are both in Shengjing, and the other two sets of prototypes are in the Institute of Optics and Mechanics and Chang Haonan''s laboratory.
So Haofa Group does not have a production line on hand. The current samples can be temporarily processed by borrowing several other sets of equipment, but future mass production will definitely not be possible.
Hence, after the contract was signed, Haojing Optics and Mechanics Institute was busier than Chang Haonan and others, working three shifts a day to produce the third set of mass production equipment for Haofa Group, striving to install it before the official contract was signed.
Even under such conditions, Chang Haonan still led the team to complete the production of two batches of five sets of parts in less than half the time stipulated in the contract...
…
2002, August 3.
England, Derbyshire.
Tim Purdy, who had just finished a technical meeting, returned to his office with a stack of documents, and then rubbed the corners of his sore eyes.
About a month and a half ago, the Trent project team unanimously agreed to find China Aerospace Power Group through Xiluo Company, and the latter would manufacture turbine discs and turbine blades using new film cooling technology.
?Although it is still in the "investigation period", the development of Trent 900 has actually started walking on two legs since then.
That is to say, while restoring the earliest design and restarting the testing process, preparing to use more fuel-efficient products to compete with the GP7200, it also continues to advance the subsequent plans to prevent China from falling behind.
It is of course good to be prepared with multiple hands.
However, the price is that almost everyone’s workload is doubled.
"director…"
?Purdy’s secretary Kelly Toulson walked in from outside:
“Recently, many people have asked me privately when the current situation will end.”
“The entire project team now works an average of more than 60 hours per week. If this continues...the union may also come to us for trouble.”
For British people, this way of working overtime is indeed a bit fatal.
?The time period is okay, but this has been going on for almost 40 days, and the sky is really boiling down.
?Hearing the other party mention the union, Bodi hesitated a little.
But in the end he shook his head;
“There’s really no way… now the two technical routes must be advanced simultaneously, and neither one can be given up.”
“When we signed the contract, we gave the Chinese people three months, and now...”
?He sighed softly, and then glanced at the date on the computer screen:
“It’s only been 38 days now... Even if they can deliver the goods on time, they will have to wait for almost seven more weeks.”
?Hearing this terrifying number, even Kelly, who had a relatively easy job, felt a little nervous and resisted the urge to roll his eyes.
“Well, you can find an opportunity to tell everyone, and after this period of time is over...”
??Poody originally wanted to invite everyone to take a vacation during the summer public holidays, but that day was the last Monday in August. According to the three-month period, not only would it be impossible to take a vacation, but he might even have to work overtime...
“During the Christmas holiday, the project team paid for everyone to take turns vacationing in the Mediterranean…”
He had no choice but to wait until Christmas.
As expected, Kelly put his hand on his forehead and shook his head.
?This pie was too far away, and it was difficult for her to tell her colleagues...
But it seems that there is really no other way.
At this moment, accompanied by the sound of hurried footsteps, a figure appeared at the door of the office in a hurry.
Even forgot to knock on the door.
“Director, Director Bodie!”
?Although Kelly blocked his view, it was not difficult to tell from the voice that the person coming was Luke Norris, who had just been under his command some time ago.
“Norris?”
??Podi frowned.
?The other party''s character is usually quite stable, but today''s appearance is really unseemly.
“Director, I just received news from Siro Company.”
Norris ignored the explanation and placed a document in his hand in front of Bodi while panting heavily:
“That batch of samples... has been completed and will be sent to us within a week... for testing!”
For a time, the only sound left in the huge office was Bodi''s heavy breathing.
“Are you talking about the batch of samples that were handed over to the Chinese for production?”
? Bodi slowly reached out his hand and opened the folder on the desktop.
?There was only a piece of paper inside, and the content written on it was exactly the same as Norris''s return just now.
“That’s right, that’s the batch.”
Norris had already taken a breath now, stood up straight and replied:
“Actually, Mr. Whittle had already gone to the Huaxia factory yesterday to inspect this batch of goods. It was just because of the time difference that we were notified now.”
??Pody feels that this world seems a little unreal.
He glanced at the date on the computer again.
Because he was worried, he looked at the calendar next to him again.
No problem, August 3rd.
???”
In fact, the three-month period was specially shortened by Bodite.
??The bottom line set internally by Rolls-Royce is that as long as the Chinese people can produce qualified products before December.
After all, after taking over a new material, process development will take some time.
but…
?No one has ever thought that this thing can be delivered ahead of schedule?
