Chapter 1117 The Big Guys Gather!

Although I had long heard about Chang Haonan's vigorous and resolute work habits, now that I have experienced it personally, it still surprised the two elders opposite.

Especially Lu Yongxiang, who was stunned for a moment before replying:

"It doesn't matter from my side... The work at the end of the year is basically over, so I can walk away."

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

As someone who has been there, he knows very well that after the results of the co-optation of academicians are finalized, many things will begin.

This unit, the local area, and even the academician’s place of origin...

As long as there is some connection, Gao Luo will have to go through a formality.

Academicians are also human beings.

And human beings are the sum total of all social relations.

It’s impossible to turn down all these invitations.

Old people like Song Wenchong and Qu Liangsheng still have a way to escape from illness, but Chang Haonan is a man who looks young and powerful at a glance, and he doesn't even have such an excuse.

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

In particular, Chang Haonan's registered workplaces at the two institutes, namely Aerospace Power Group and Beijing Hangzhou University, are still in the capital.

Generally speaking, there should be more trouble.

Chang Haonan waved his hand directly:

"Need not……"

"What needs to be said has been said in the past two years... The last batch of graduate students who have listened to my lectures have not graduated yet... Besides, I left Haojing in early October. , It’s been two months now, and I can only learn about the project status through reports, which makes me a little bit uneasy.”

Lu Yongxiang was also happy when he heard this:

"That's true... when you first won the Philippines Award two years ago, the popularity was much higher than it is now."

"At that time, the Department of Mathematical Physics reported to me that they were going to ask you to come and give a report to the academicians... But later I heard that there were too many people inviting you, so we co-organized it with Yanda and Qinghua University. One game.”

Although the honors on both sides are not in the same evaluation system, there are still about a hundred more academician titles in each selection, and the average number of Philippine Award winners is only one per year.

After all, the latter is rarer.

Moreover, he is the first native Chinese scholar.

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

In fact, Chang Haonan had an impression that the latter originally held the title of professor at Haojing Jiaotong University.

However, the actual work location may not be directly related to this.

Just like Lu Yongxiang is still a professor at Zhejiang University, but he has basically stayed in the capital these years.

"It's even better on my side."

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

"Although I have often traveled to Jincheng and Haiyan over the years, my base has remained in Haojing and has never moved..."

"Speaking of which, when we get there, I should actually be the real host... then I have to be given the opportunity to fulfill my duties as a landlord."

"..."

Since all three people had no objections, Lu Yongxiang finally set the tone:

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

…

Although he said that he didn't need to stay in the capital, the school and the headquarters did still have some things to deal with.

Just like over there in the Torch Laboratory——

If the leader evaluates the academician, then there must be some benefit to the people who follow him, right?

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

Although the group level cannot directly distribute money for this reason, after all, two (three new) academicians have been added within a year, and some real benefits must be provided to increase the morale of the employees below.

In the field of aviation development, we often have to work hard day and night to solve key problems. We can't just make the pie bigger and let the comrades work hard, right?

In short, by the time he actually returned to Haojing, it was already Saturday afternoon five days later.

In order to express their attention, the Qin Provincial Reception Office even specifically contacted the Aviation Power Group and said that it could directly send people and vehicles to the airport to greet them.

Considering that academicians are directly benchmarked against deputy ministerial leaders in terms of remuneration, this is not an unusual process.

But...

Due to his special status, Chang Haonan was always sent directly to Yanliang Airport by a special plane.

There was no way to get in at the local reception office.

So in the end I had to let it go.

Of course, not surprisingly.

At the entrance of Haofa Group, Chang Haonan still saw the banners being held from a distance and the crowds lined up to greet them.

Fortunately, it's not too big. I guess there are about thirty or forty people there.

It should be the leaders of various offices in the agency.

The two leaders were Ren Bingda and Zhang Zhenhua.

Chang Haonan doesn't like ostentation, but he also knows that this kind of process cannot be avoided at all.

If you really reject it completely, it will seem a bit unhuman.

So after getting off the bus, I had a lively celebration with everyone, and then took a group photo before sending everyone back.

Only then did Zhang Zhenhua find Chang Haonan alone. While following the latter to the design room, he reported the situation in detail:

"Mr. Chang, after our comrades worked overtime to make progress, we have now completed the trial production of the first batch of fan blade samples. After testing, three of them were confirmed to be qualified... Do you think we will start testing the balance characteristics and fatigue characteristics immediately?"

The aerodynamic characteristics of fans can be tested in wind tunnels in the early stages using scale models or wooden models.

But the performance in terms of structure and lifespan must be as good as the original.

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

In the current situation where it takes only two months to produce 2-3 qualified samples, we naturally have to give priority to the latter two.

"Can……"

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

"In this way... let the comrades of the project team rest first and recharge their batteries before officially starting the test the day after tomorrow."

Such instructions are rarely heard from Chang Haonan's mouth.

So much so that Zhang Zhenhua staggered with his left foot and almost fell to the ground:

"ah?"

Although the test cannot begin until Chang Haonan signs off, he actually had someone go to debug the equipment and install the blades to be tested last night.

As a result...it seems that I couldn't guess what the leader meant.

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

"That's right. This time in Beijing, I contacted two groups of technical personnel to participate in our project development work. They will send representatives to visit here next Monday... If the test is started in advance, it will be suspended by then. It’s inconvenient, so 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 just now, suddenly spoke:

"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:

"The ostentation should not be too big, but the specifications must still be ensured. After all, the team is led by Academician Lu Yongxiang and Academician Qu Liangsheng..."

"ah?"

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 "requiring specifications but not ostentation" is indeed a bit divisive.

on the other hand……

Why does the project team's formation suddenly seem to be different from before?

Three academicians gathered together to work on a project.

How could this blessing be so small?

…

There is really nothing to say about Ren Bingda's work ability.

It only took one day to meet Chang Haonan's request to compete with the "colorful black", and completed the reception task in a low-key and graceful manner.

Although it is a seminar, it is an engineering project after all, and it is impossible for a group of people to just sit in a conference room and talk about it on paper.

Therefore, as usual, Chang Haonan first arranged a round of visits.

The most important thing is naturally the dynamic characteristics testing equipment.

Horizontal high-speed rotation tester.

When everyone came to the test workshop, the three qualified blades that had passed the test had been installed on it, and the staff were busy making final calibrations.

Although the other two academicians are not professionals in aviation, they are by no means outsiders and are no strangers to impeller equipment.

However, the three samples in front of me seemed 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 our country to follow it so quickly?"

Although the key point that Chang Haonan wants to show is not the blade itself, he must still be happy when he hears others praise him so:

"This type of wide-chord fan blade was indeed the first to be put into use by Rolls-Royce... Of course, frankly speaking, we did draw on some experience from the British, but overall, this is still completely developed by our own technical forces. and produced.”

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 for a long time:

"This equipment has plenty of spare capacity for the speed increaser and motor..."

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

"Then as long as the acceleration sensor and eddy current displacement sensor can be upgraded, it will meet the requirements..."

It was clear that he was completely immersed in it.

And Lu Yongxiang, who was a little off topic just now, also took two steps forward:

"There is indeed no problem with the test equipment, but the speed of more than 100,000 rpm is a test for the design and manufacturing level of our rotors... If the unbalanced vibration problem is really 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 with a speed of 10,000 rpm and a centrifuge tube weighing tens of grams is not fully balanced, it is enough to make an unlucky graduate student see too much milk.

One hundred thousand revolutions, still with a kilogram-level rotor.

Not to mention dry-crushing the entire workshop, destroying the entire equipment is not a big problem anyway.

This sentence actually pulled Qu Liangsheng out of his own world:

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

The person with the best mentality is Chang Haonan:

"You two don't need to be under such great psychological pressure... Although we have not actually tested it above 100,000 rpm, in the aviation engine industry, turbine tests of tens of thousands of rpm are still very common."

"You know, for this type of mass-produced product, it is impossible to guarantee 100% balancing. So I added an unbalanced compensation module to the control system of the electromagnetic bearing, which 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, which can offset part of the unbalanced vibration..."

"..."

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