Chapter 1117 Big bosses gathered together!
Although I have heard about Chang Haonan's vigorous and resolute work habits for a long time, now I have experienced it personally, which still surprised the two elders opposite.
Lu Yongxiang, in particular, 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 you can go away."
"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...
Anyone who can be related to me has to be invited to go through the ceremony.
Academicians are also human beings.
People are the sum of all social relationships.
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 can be seen as young and powerful at a glance, and he doesn't even have such an excuse.
So, at least for the first month, it will be difficult to get back to the normal work rhythm.
In particular, Chang Haonan’s registered workplaces at the two institutes, namely the Aerospace Power Group and Beijing Hang University, are still in the capital.
Generally speaking, there should be more troubles.
Chang Haonan, on the other hand, waved his hand directly:
"No need..."
"What needs to be said has been said in the past two years... The last batch of people listened to me The fresh graduate students attending the lecture have not graduated yet... Moreover, I left Haojing in early October, and it has been two months now. In the meantime, I can only understand the status of the project through reports, which is somewhat limited. Don’t worry.”
Lu Yongxiang was also delighted 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.”< br>
"At that time, the Department of Mathematical Physics reported to me that they were going to ask you to come over 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 can be more than a hundred academician titles in each selection, and the average number of Philippine Award winners is only one per year.
After all, the latter is more rare.
Besides, he is also 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.
“I have no problem here.”
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..."
"When it comes to getting there, in fact I should be the real host..." …Then you have to give me a chance to show my kindness as a landlord.”
“…”
Since the three of them had no objections, Lu Yongxiang finally made the decision:< br>
“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.
For example, at the Torch Laboratory -
If the leader evaluates the academicians, then there must be some benefits to the people who follow him, right?
So Chang Haonan gave everyone a few more 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.
Engaging in aerospace development involves high-intensity research on key problems day and night. You can’t just make the pie bigger and let comrades struggle, right?
Anyway, by the time he actually returned to Haojing, it was already Saturday afternoon five days later.
To express their attention, the Qin Provincial Reception Office even specifically contacted the Aviation Power Group and said that they could directly send people and vehicles to the airport to greet them.
Considering that academicians directly benchmark 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.
The local reception office cannot be entered at all.
So in the end we had to let it go.
Of course, not surprisingly.
At the entrance of Haofa Group, Chang Haonan could still see the banners held in the distance and the crowd lined up to greet them.
Fortunately, the scale is not too big, with a visual estimate of about thirty or forty people.
It should be the leaders of various offices of the agency.
The two leaders are 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.
Until now, Zhang Zhenhua found Chang Haonan alone. While following the latter to the design room, he reported the situation in detail:
"Mr. Chang, after comrades worked overtime to make progress, The trial production of the first batch of fan blade samples has now been completed, and three of them have been confirmed to be qualified... Do you think we will start testing the balance characteristics and fatigue characteristics immediately? "
The aerodynamic characteristics of the fan, in In the early stage, you can use scale models or wooden models to conduct experiments in wind tunnels.
But the performance in terms of structure and lifespan must be as good as the original.
After all, even in hollow blades, the truss-type hollow structure is already considered the latest second-generation product. 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.
“But...”
Chang Haonan just wanted 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:
"Huh?"
Although the test cannot begin until Chang Haonan signs, But last night he actually had people go to debug the equipment and install the blades to be tested.
As a result...it seems that I couldn't guess what the leader meant.
Chang Haonan thought the other party was simply surprised, so he explained:
"That's it. This time in Beijing, I contacted two more groups of technicians to participate in our project development work. , they will send a representative to visit here next Monday... If the test is started in advance, it will be suspended at that time, which will be inconvenient. It is 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 answered:
"Then Mr. Chang, do you want to prepare for the reception?"
He is responsible for these tasks.
“This is definitely needed.”
Chang Haonan nodded:
“The ostentation should not be too big, but the specifications must still be guaranteed. After all, the team was led by Academician Lu Yongxiang and Academician Qu Liangsheng..."
"Ah?"
Ren Bingda and Zhang Zhenhua looked at each other, and they both saw obvious surprise in each other's eyes.
On the one hand, the requirement of “standards, not ostentation” is indeed a bit divisive.
On the other hand...
Why suddenly, the project team's formation seems to be different from before?
Three academicians gathered together to work on a project.
Can this blessing be so small?
……
Ren Bingda’s work ability is really nothing to say.
It only took one day to satisfy 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.
So 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 seem a little different.
“Wide chord, swept back, no shoulder structure...”
Academician Lu pushed up his glasses:
“I remember the technical work in a British paper I’ve seen similar designs in the literature, but I didn’t expect it to be followed so quickly in China.”
Although the focus of Chang Haonan's presentation is not the blade itself, he must still be happy to hear others praise it:
"This type of wide-chord fan blade was indeed the first to be put into use by Rolls-Royce... Of course, frankly speaking, we have indeed learned from some experience of the British, but in general, this is still completely organized by our own technical strength to develop and produce.”
Qu Liangsheng is more concerned about it. As for the test equipment itself, as soon as I entered the door, I ran to the nameplate and stared at it for a long time:
"This equipment has sufficient margin for the speed increaser and motor..."
"Ouch! 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..."
Obviously, he has been completely immersed in it.
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 very difficult for the design and manufacturing level of our rotors. It’s a test... 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 its power...
If a laboratory centrifuge with 10,000 revolutions and can process centrifuge tubes weighing tens of grams is not fully balanced, it will be enough for an unlucky graduate student to meet his wife.
One hundred thousand revolutions, still with a kilogram-level rotor.
Not to mention smashing the entire workshop, destroying the entire equipment is not a big problem anyway.
This sentence pulled Qu Liangsheng out of his own world:
"On this point, 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 have to be so big-hearted. Pressure... Although we have not actually tested more than 100,000 rpm, in the aviation industry, turbine tests of tens of thousands of rpm are still very common.”
“You know, for this type of mass-produced products. It is said that it is impossible to guarantee 100% balance, so I specially added an unbalance compensation module to the electromagnetic bearing control system, 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 On the electromagnetic bearing, this can offset part of the unbalanced vibration..."
"..."
Listening to his description, Lu Yongxiang and Qu Liangsheng gradually showed expressions of surprise and joy...
