The military-industrial scientific research system of the academic master.

When Chang Haonan saw the sample trial production contract in the meeting room of Gaofa Group, he immediately laughed out loud...

"Uh... Mr. Chang?"

Ren Bingda was still a little confused.

"nothing."

Chang Haonan was wearing a blue work suit that he hadn't worn for a while. He shook his head with a hint of sarcasm:

"RB211-524B4... The British are really careful..."

He flicked a document on the table and explained to the other party:

"This model is a Boeing 747-200, and it has the power of the L1011-200. It is almost 20 years old and will soon be eliminated... How could there be any special-shaped air film holes that need us to process?"

"To put it bluntly, they still don't trust our level and are worried that someone will take away our useful technical information... So they're sending out a less advanced old guy to test the waters first."

After the words were made clear, Ren Bingda naturally understood immediately and quickly came over to ask:

"Then let's..."

"Maintaining the status quo."

Chang Haonan didn't wait for him to finish his question and answered directly:

"No matter what, the British are Party A... In fact, they are Party A's Party A, and this is also the first time they have such in-depth cooperation with us, so it's normal for them to be a little suspicious..."

"In addition, the RB211 engine is relatively conservative in its use of materials. According to the information provided by Rolls-Royce, although the specific grades are different from ours, the turbine part is still mainly made of nickel-based alloys. In this way..."

When the two were halfway through their conversation, they heard some chaotic footsteps in 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 spoke loudly.

"come in."

Chang Haonan had to temporarily stop the topic, signaled everyone to take their seats in order, then opened the technical information in front of him, and prepared to begin introducing the key technical aspects of this sample production.

However, when he raised his head again, he inadvertently caught a glimpse of a somewhat familiar face in the crowd.

Chang Haonan searched in his mind and soon found a name that matched the number:

"You are... Comrade Zhang Zhenhua?"

Zhang Zhenhua was the director of the technical department when Factory 430 had not yet been fully transformed into Gaofei Group.

He was also one of the representatives sent by Factory 14 to Shengjing to learn from Chang Haonan when he was carrying out the precision engineering plan based on the turbojet 430 project.

He later participated in the WS-10 project and played an important role in the verification of some technologies.

However, as the testing of the WS-10A, the technical verification model of the WS-9, began, 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 never met again.

It's been nearly four years since we last met.

Zhang Zhenhua, who was still in his prime back then, now has gray hair at the temples.

And considering the other person's age, the mere passage of time may not be enough to bring about such a huge change.

Obviously, he was also worried about the Gaofa Group...

"Mr. Chang."

Zhang Zhenhua, who was called by name directly by Chang Haonan, stood up and shook hands with the former with a somewhat evasive look:

"I'm really ashamed..."

The expression on his face was somewhat gloomy:

"After so many years, there is now an opportunity in front of our Gaofa Group, but we still have to trouble you, Mr. Chang, to personally lead the project..."

After so many years, Zhang Zhenhua's title is still the Director of the Technical Department of Gaofa Group.

The pace of progress has indeed lagged behind.

Of course, this is also related to the actual situation of Gaofa Group.

The WS-9 digested and absorbed technology, and the D436 was directly introduced for final assembly. It is not easy for the NK32 to fully master it in a short period of time.

The self-developed WS-20 is still in the preparation stage...

In short, compared with the big brother next door, the results are indeed not very impressive.

"What's this..."

Chang Haonan smiled and said comfortingly:

"After all, ultra-short laser processing is a technology that I developed. It's normal that you are not familiar with it and are not used to it for the first time."

"In Shengjing, it was only after I led them through the process that some people gradually began to take on the responsibility..."

"And from another perspective, using ultrashort lasers to replace continuous lasers is an idea that can be concealed for a while, but not forever. If the technology itself is really that simple and you can become fully familiar with it in one or two years, then other countries will also be able to catch up quickly, right?"

This angle was indeed quite fresh and refined, so much so that Zhang Zhenhua, who had been feeling a little depressed just now, was stunned for a long time after hearing it.

Then I think it does make some sense...

"Okay, let's get to the point."

We are all adults now, and we can only rely on ourselves to adjust our mentality, so Chang Haonan didn't say anything more, but stood up and walked behind the small podium:

"I think you all 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 we can directly use the database we built earlier."

He turned on the computer and a page of PPT appeared on the screen:

"Of course, the specific parameters of the British base material are quite different from ours, so we still need to use the blank material provided by them to conduct several rounds of experiments..."

"..."

For Chang Haonan, this process is basically a piece of cake.

Although the workload is not low, there are sufficient manpower after all, and there are also several experienced veterans coming from the 606 Institute.

The only problem is the equipment.

The Haojing Institute of Optics and Fine Mechanics has currently produced a total of four sets of ultra-short laser processing equipment, including the prototype.

The two mass-produced models are in Shengjing, and the other two prototypes are in the Institute of Optics and Electronics and Chang Haonan's laboratory respectively.

Therefore, Gaofa Group does not have a production line on hand.

The current samples can be temporarily processed using several other sets of equipment, but this will definitely not be possible for mass production in the future.

Therefore, after the contract was signed, the Gaojing Institute of Optics and Fine Mechanics was even busier than Chang Haonan and others. They worked in three shifts a day to produce the third set of mass production equipment for the Gaofa Group, striving to have it installed before the formal contract was signed.

Even under such conditions, Chang Haonan still led the team to complete the production of two batches of a total of five sets of parts in less than half the time stipulated in the contract...

……

2002, April 8.

Derbyshire, England.

Tim Bodie, who had just finished a technical meeting, returned to his office with a pile of documents and rubbed his sore eyes.

About a month and a half ago, the Trent project team unanimously agreed to find China Aviation Power Group through CIL to have the latter produce turbine discs and turbine blades using the new air film cooling technology.

Although it is still in the "investigation period", the research and development of Trent 900 has actually started on two legs since then.

That is, while restoring the earliest design and restarting the testing process, preparing to compete with GP7200 with a more fuel-efficient product, it also continued to advance later plans to prevent China from falling behind.

It is certainly good to have multiple preparations.

However, the cost is that almost everyone's workload has doubled.

"director……"

Bodie's secretary Kelly Turson walked in from outside:

"Recently, many people have asked me privately when this situation will end."

"The average working time for the entire project team is now over 60 hours per week. If this continues... the union may cause trouble for us."

For the British, this way of working overtime is really a bit fatal.

The period of time is okay, but this has been going on for nearly 40 days, and the situation down there is really in turmoil.

When the other party mentioned the union, Bodi hesitated for a moment.

But in the end he shook his head;

"There's really no other way... Now the two technical routes must be advanced simultaneously, and neither can be abandoned."

"When we signed the contract, we gave the Chinese three months. Now..."

He sighed softly, then glanced at the date on the computer screen:

"It's only been 38 days now... Even if they can deliver on time, it will take another seven weeks."

Hearing this terrifying number, even Kelly, who had a relatively easy job, felt a little scared and resisted the urge to roll his eyes.

"How about this, you find a chance to tell everyone, after this busy period is over..."

Bodi originally wanted to invite everyone to go on vacation during the summer public holiday, but that day was the last Monday in August, and according to the three-month deadline, not only would they not be able to take a vacation, they might even have to work overtime...

"During the Christmas holiday, the project team will pay for everyone to take turns to go on vacation in the Mediterranean..."

He had no choice but to stick with it until Christmas.

As expected, Kelly put his hand to his forehead and shook his head.

This pie is so far-fetched that it is difficult for her to tell her colleagues...

But it seems that there is really no other way.

At this moment, accompanied by a burst of hurried footsteps, a figure appeared in front of the office door in a hurry.

Even forgot to knock.

"Manager, Manager Bodi!"

Although his view was blocked by Kelly, it was not difficult to tell from the voice that the person coming was Luke Norris, who had been recruited by him some time ago.

“Norris?”

Bodie frowned.

The other person's personality is usually quite stable, but today he looks really inappropriate.

"Manager, I just... just received news from Xiluo Company."

Norris didn't bother to explain. He gasped and put a document in front of Bodie:

"They say that the batch of samples... has been produced and will be delivered to us within a week... for testing!"

For a moment, the only sound in the huge office was Bodi's heavy breathing.

"Are you talking about... the batch of samples that were given to the Chinese to produce?"

Bodie slowly reached out his hand and opened the folder on the desk.

There was only a piece of paper inside, and the content on it was exactly the same as what Norris had just reported.

"Yes, that batch."

Norris had already caught his breath, stood up straight and replied:

"In fact, Mr. Shitel had already gone to the Huaxia factory to check on the goods yesterday. It was only because of the time difference that he notified us now."

Bodie felt that this world seemed a little unreal.

He glanced again at the date on his computer.

Because I was worried, I took another look at the calendar next to me.

Nothing wrong, August 8rd.

"???"

In fact, the three-month period was deliberately shortened by Bodi.

The bottom line set internally by Rolls-Royce is that as long as the Chinese can produce qualified products before December, it will be fine.

After all, after taking over a new material, it will take some time to develop the process.

but……

No one has ever thought that this thing could be delivered ahead of schedule?
