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

Although they had heard about Chang Haonan's vigorous and efficient work habits a long time ago, the two old men on the opposite side were still a little surprised after experiencing it firsthand.

Especially Lu Yongxiang, after a moment of hesitation, he replied:

"It's okay for me... I'm basically done with my work at the end of the year, so I can leave."

"But Academician Chang, are you sure you don't need to stay in the capital for a while longer?"

As someone who has been through it, he knows very well that many things will only begin after the results of the election of academicians are finalized.

The unit, the local area, or even the academician’s hometown…

Anyone who has any connection with the matter will be invited to go through the motions, no matter how high or low.

Academicians are also human beings.

And man is the sum of all social relations.

It's impossible to turn down all these invitations.

Older people like Song Wencong and Qu Liangsheng could still escape due to illness, but Chang Haonan looked young and strong at first glance, so he didn't even have this excuse.

Therefore, at least for the first month, it is difficult to return to the normal work rhythm.

In particular, Chang Haonan’s registered work units in the two academies, namely, Aviation Power Corporation of China and Beijing University of Aeronautics and Astronautics, are both in Beijing.

Generally speaking, there should be more trouble.

Chang Haonan simply waved his hand:

"Need not……"

"I have already said almost everything I need to say two years ago... The last batch of graduate students who attended my lectures have not graduated yet... Besides, I left Gaojing in early October, and it has been two months now. I can only learn about the project status through reports, which makes me a little worried."

Lu Yongxiang was also happy to hear this:

"That's true... When you won the Fields Award two years ago, you were much more popular than you are now."

"At that time, the Department of Mathematics and Physics reported to me that they were planning to invite you to give a lecture to the academicians... but later I heard that too many people wanted to invite you, so they co-organized it with Yanda and Qinghua."

Although the honors on both sides are not evaluated using the same system, there are always at least a hundred more academician titles selected each time, while the average number of Fields Medal winners is only one per year.

After all, the latter is more rare.

Moreover, he is the first native Chinese scholar to do so.

After briefly deviating from the topic, the two turned their eyes to Qu Liangsheng opposite them.

In fact, Chang Haonan did have an impression of the latter, as the latter originally held the title of professor at Haojing Jiaotong University.

However, the actual work location may not have a direct relationship with this.

For example, Lu Yongxiang is still a professor at Zhejiang University, but he has basically stayed in Beijing in recent years.

"There's no problem on my side."

Qu Liangsheng took off his reading glasses, wiped them gently and said with a smile:

"Although I have been traveling to Jincheng and Haiyan frequently in recent years, my base is still in Gaojing..."

"Speaking of which, if we really get there, I should be the real host... Then you have to give me a chance to fulfill my duties as a good host."

"..."

Since the three people had no objections, Lu Yongxiang finally decided:

"Then it's settled, next Monday, at the Gaofa Group!"

……

Although he said that he didn't need to stay in Beijing for long, there were indeed some things that needed to be dealt with at school and headquarters.

For example, at the Torch Lab—

If the leader is elected as an academician, then the people working under him should get some benefits, right?

So Chang Haonan granted everyone a few more days of leave before New Year's Day and gave them an extra subsidy as a bonus.

Although the group cannot directly give money for this reason, after all, two (three) new academicians were added within a year, so some tangible benefits must be provided to boost the morale of the employees below.

Working in aerospace development involves intensive research day and night. We can't just rely on empty promises to get our colleagues to work hard, right?

In short, when he finally returned to Haojing, it was already Saturday afternoon five days later.

To express its importance, the Qin Province Reception Office even contacted the Aviation Power Group and said that it could directly send people and cars to the airport to pick them up.

Considering that the remuneration of academicians is directly comparable to that of vice-ministerial leaders, this is not an unusual procedure.

But...

Due to his special identity, Chang Haonan has always been sent directly to Yanliang Airport by a special plane.

There is no way to get into the local reception office.

So in the end it just ended up being left unresolved.

Of course, no surprise.

At the gate of Gaofa Group, Chang Haonan could still see the banners and the crowds lined up to welcome him from afar.

Fortunately, the scale was not too large, and there were estimated to be about thirty to forty people.

They should be the leaders of all offices in the agency.

The two leaders were Ren Bingda and Zhang Zhenhua.

Chang Haonan didn't like ostentation, but he knew that this process was unavoidable.

If you really refuse completely, it would seem a bit inhumane.

So after getting off the bus, we still celebrated with everyone, and then took a group photo before sending everyone back.

It was not until this moment that Zhang Zhenhua found Chang Haonan alone. He followed the latter to the design studio and reported the situation in detail:

"Boss Chang, after our colleagues worked overtime to catch up with the progress, we have now completed the trial production of the first batch of fan blade samples. After testing, three blades have been confirmed to be qualified... Do you think we should start the balance and fatigue property tests right away?"

The aerodynamic characteristics of the fan can be tested in a wind tunnel using a scaled model or a wooden model in the early stages.

But in terms of structure and lifespan performance, only original parts can be achieved.

After all, the truss-type hollow structure is already the latest second-generation product even among hollow blades. Compared with the honeycomb-type hollow structure, there is less known data and the design risk is higher.

As it only takes two months to produce 2-3 qualified samples, the latter two items must naturally be given priority.

"Can……"

Chang Haonan was about to agree, but suddenly he had a better idea:

"Well... let the project team take a break first, just like recuperating and gathering our strength, and then we can officially start the test the day after tomorrow."

Such instructions are rarely heard from Chang Haonan.

As a result, Zhang Zhenhua tripped over his left foot and almost fell to the ground:

"what?"

Although the test had to wait for Chang Haonan's signature before it could begin, he had actually asked people to debug the equipment and install the blades to be tested last night.

As a result...it seems that I failed to guess what the leader meant.

Chang Haonan thought the other party was simply surprised, so he explained:

"It's like this. This time in Beijing, I contacted two more groups of technicians to participate in our project development work. They will send representatives to visit us next Monday... If we start the test ahead of time, we will have to pause it, which is inconvenient. It's better to wait one more day before starting."

Zhang Zhenhua breathed a sigh of relief.

At this moment, Ren Bingda, who had been silent, suddenly spoke up:

"Then Mr. Chang, do you want to prepare for the reception?"

He is responsible for all these tasks.

“This is definitely needed.”

Chang Haonan nodded:

"It doesn't have to be too grand, but the standards must be met. After all, the team is led by Academician Lu Yongxiang and Academician Qu Liangsheng..."

"what?"

Ren Bingda and Zhang Zhenhua looked at each other and saw obvious surprise in each other's eyes.

On the one hand, the requirement of "standards over pomp" is indeed a bit divisive.

on the other hand……

How come the project team's formation suddenly seems different from before?

Three academicians are working on one project.

How can this blessing be small?

……

There is indeed no doubt about Ren Bingda's work ability.

In just one day, Chang Haonan's requirement for "colorful black" was met, and the reception task was completed in a low-key but graceful manner.

Although we are here for a seminar, this is an engineering project after all, and it is impossible for a group of people to just be locked in a conference room and talk about it on paper.

Therefore, according to convention, Chang Haonan first arranged a round of visits.

The most important thing, of course, is the dynamic characteristics test equipment.

Horizontal high-speed rotation tester.

When everyone arrived at the testing workshop, the three qualified blades that passed the inspection had already been installed on it, and the staff were busy carrying out the final calibration.

Although the other two academicians are not from the aviation field, they are by no means laymen and are familiar with impeller equipment.

However, the three samples in front of us seem a little different.

"Wide chord, swept back, no shoulder structure..."

Academician Lu pushed up his glasses:

"I remember seeing a similar design in a British technical document before. I didn't expect that our country would follow up so quickly?"

Although Chang Haonan's focus was not on the leaves themselves, he must have been happy to hear others praising him like this:

"This type of wide-chord fan blade was indeed first used by Rolls-Royce... Of course, to be honest, we did learn from some of the British experience, but overall, this was developed and produced entirely by our own technical strength."

Qu Liangsheng was more concerned about the test equipment itself. As soon as he entered the door, he ran to the nameplate and stared at it intently for a long time:

"The speed increaser and motor of this equipment have sufficient margin..."

"Wow! This vibration analyzer is made by Schenck..."

"Then as long as we can upgrade the acceleration sensor and eddy current displacement sensor, we can meet the requirements..."

Obviously, he was completely immersed in it.

Lu Yongxiang, who had been off topic a little bit earlier, also took two steps forward:

"There is indeed no problem with the test equipment, but a speed of more than 100,000 rpm is a test for our rotor design and manufacturing level... If the unbalanced vibration problem is not controlled, the associated losses will be huge..."

The so-called unbalanced vibration is the vibration of the rotor caused by eccentric centrifugal force.

As for the power...

If a laboratory centrifuge that runs at 10,000 rpm and handles centrifuge tubes weighing dozens of grams is not adequately balanced, it can be enough to send an unlucky graduate student to see his grandmother.

One hundred thousand revolutions, and it still has a kilogram-level rotor.

Not to mention destroying the entire workshop, it would not be a big problem to destroy the entire set of equipment.

This sentence pulled Qu Liangsheng out of his own world:

"Regarding this, I will do my best to ensure the balance of the rotor..."

The one with the best mentality is Chang Haonan:

"You two don't need to feel so much psychological pressure... Although we haven't actually tested it above 100,000 rpm, in the field of aero engines, turbine tests at tens of thousands rpm are still very common."

"As you know, it is impossible to guarantee 100% balance for this type of mass-produced product. So I added an unbalance compensation module to the control system of the electromagnetic bearing. It calculates the compensation current based on the position of the unbalanced mass or the direction of the unbalanced force, and then applies it to the electromagnetic bearing. This can offset some of the unbalanced vibration..."

"..."

Listening to his description, Lu Yongxiang and Qu Liangsheng gradually revealed expressions of surprise and joy...
