Chapter 390 Two exclusive interviews in three months?
Since the nationwide flood fighting and rescue operation at the organizational level is still ongoing, according to the process, it is indeed not yet time to show the settlement screen, so Chang Haonan can only temporarily reconcile with the two leaders today.
As for how much we can gain in the future, it depends not only on individual efforts, but also on the process of history.
However, the efficiency shown by Ding Gaoheng and Cao Gangchun in this matter is indeed quite amazing.
Two days later, Beijing Hang University Supercomputing Center.
Chang Haonan and several other core technicians responsible for the overall design of the software and writing of module functions are gathering together to listen to Sun Huizhong's report on the overall situation of aerodynamic design optimization of the new advanced trainer aircraft.
Compared with the previous project of Professor Rui Xiaoting of Jinling University of Science and Technology on overall system dynamics analysis of long-range rocket launchers, what Guizhou Airlines is doing here is after all a more complex aircraft design, although it may not necessarily be the same in terms of calculation amount. The former is higher, but the advantage is that they are basically applied to almost all functions designed for software at this stage.
And the trial version is also closer to the "public beta version" that will be launched for users soon.
Although under the management and supervision of Chang Haonan, this set of things will definitely not have any major problems in the core numerical calculation methods and operating logic, but as a software, a user-oriented commercial software, To achieve true success, these core-level factors can only account for at most half.
The other half is user experience content such as human-computer interaction, I/O design and compatibility.
This is also the part that the system is completely unable to handle.
Most of the members of the Chang Haonan project team are developers who prefer computer or applied mathematics and have little experience in the pain points of industrial software applications. However, Chang Haonan leads the entire development process. The level of familiarity with the software is so high that even if there is a problem, it is likely that you will not be able to experience it.
It's like writing a paper. Even if the author checks it ten times and hands it over to another person, he can often find new clerical errors.
At this time, Sun Huizhong was standing in front of a blackboard, introducing the design process of the entire aircraft, while Chang Haonan was sitting below for the first time, opening a small notebook and taking notes.
When he first started speaking, the former's tone even trembled with excitement.
After all, there are not many opportunities to give lectures to big bosses like this.
“Let me first introduce the overall design process of this type of aircraft, as well as the key technical indicators...”
“Compared with the J-7F aircraft, the overall structure after the 5845mm position remains unchanged. , and the front is redesigned, using the most cutting-edge DSI air inlet and nose retractable side strips, which can ensure maneuverability within a 70° angle of attack range..."
"Enter The airway design points are: maximum Mach number Ma=1.3; pre-compression bulge equivalent compression half-cone angle is 20°; height is 11km and the capture area is determined based on this, and the flow rate at the maximum state of the engine is within the range of Ma=0.7-1.1Ma Determine the throat area and control the throat Mach number at Ma=0.5-0.7..."
"Considering that my own technical level is relatively limited, and after all, this model is improved from a mature active model. Therefore, throughout the design process, I mainly used more traditional calculation methods. For example, I still used the improved surface element method to calculate the steady aerodynamic force of the whole machine, but when calculating the local convex hull shape of the DSI inlet In the process of making surface curves, I still tried to use the new dimensionality reduction method of nonlinear partial differential equations provided in the software to numerically solve the N-S equation..."
Following Sun Huizhong's introduction on the stage, the following people, especially those who had participated in some actual projects, began to write furiously. For a while, apart from the voice of the former speaking, there were only the occasional pages turning in the notebook or the keyboard while typing. Knocking sound.
Due to the lack of previous experience in giving presentations on stage, Sun Huizhong’s introduction was somewhat indifferent, so it took a lot longer than expected.
But in the end, he finally said what everyone wanted to hear.
Just as Sun Huizhong was preparing to finish, there was a sudden knock on the door of the conference room.
A teacher in charge of administration at the supercomputing center stood outside.
"Director Chang, there is someone looking for you outside."
Generally speaking, outsiders cannot enter the computer room area without permission, so someone needs to report it.
As for the other party to come directly into this kind of meeting, it is obviously impossible for it to be just anyone.
You still have to go down and have a look.
Fortunately, the really valuable content in the entire report has come to an end. As for the ending part...
Just don’t talk about it.
So, just after he stood up and announced that the meeting would be suspended for a while, Sun Huizhong on the stage was almost instantly surrounded by several people who had been eager to try from the beginning.
"Gong Sun, do you think there is any room for improvement in the user interface of our software..."
"Do you think the new fully automatic meshing method is easy to use... …”
“Is the technical instruction manual we included with the software comprehensive?”
"Which multi-objective optimization strategy did you choose during design..."
The questions that kept ringing in his ears made Sun Huizhong's head as big as a bucket. Fortunately, Chang Haonan did not forget to let these urgent questions go before leaving the venue. Engineers lined up to ask questions about the modules they were involved in, giving the former time to respond to questions one by one.
"Huh...So Director Chang faces this kind of scene after every meeting..."
Sun Huizhong finally breathed a sigh of relief and thought this way.
On the other side, Chang Haonan, who was leaving the conference room, took out his mobile phone from his pocket and took a look.
As expected, there were several missed calls.
He muted his voice during the meeting just now, so he didn’t even answer the call.
It seems that the other party had no choice but to come directly to the door because they had not been able to contact him.
While thinking this way, he had already arrived at the reception room near the entrance on the first floor of the supercomputing center.
There are several people sitting inside. Chang Haonan actually knew the leader——
It was the CCTV female host who came to Beijing Airlines to do an exclusive interview with him just a few months ago after he won the China Youth May 4th Medal.
Seeing Chang Haonan walking in from the door, the other party immediately stood up.
"For this meeting, I should call Director Chang, good afternoon."
The two shook hands.
Even though Ni Ping was experienced and well prepared, he still couldn't help feeling emotional when he faced Chang Haonan again.
Others may not know the latter’s true age, but she knows it.
After all, just three months ago, the other party was still an undergraduate student at Beijing Hang University.
Calculating the time now, not long after graduation, it turns out that I have already started to hold leadership positions in the field of scientific research.
It’s outrageous. You can’t rise so fast on a rocket.
"Ms. Ni, I haven't seen you for a few months, but you are still as brilliant as ever."
Chang Haonan is now somewhat accustomed to this kind of scene, and knows that the best way to deal with it at the moment is to change the topic:< br>
“I wonder how I can help this time?”
“I have received a request from above to give you another exclusive interview. The topic is about the software you developed. I need to set up flood-fighting and disaster relief equipment, so I have to come here to bother you again.”
Ni Ping added an accent to the word “Zai”.
Indeed, even in the entire history of central media, it is rare that the same person is interviewed twice within three months, and it is because of completely different things.
Although Chang Haonan's contribution this time is indeed not small, the fact that even official publicity can be arranged so quickly is probably inseparable from some work done by Ding Gaoheng and Cao Gangchun.
For Chang Haonan, who has already had a similar experience, doing interviews is already something he is familiar with.
And facing the camera again, he didn’t feel as nervous as he did at the beginning.
“Then let’s start now?”
Chang Haonan took the opportunity to sit opposite Ni Ping.
"You may have to appear on camera this time, so you need to put on simple makeup first, otherwise your face will be very dark."
The latter immediately called the accompanying makeup artist.
As Chang Haonan holds more and more positions and can mobilize more and more resources, his existence cannot be hidden.
And the MA-60 project and aircraft anti-icing research, which had been used as shields before, have gradually failed to keep up with his progress.
And it just so happened that his contribution to the flood relief process perfectly met the requirements for "public promotion reason": the influence was large enough, the research content was not sensitive, and there were only a few people who knew the inside story.
So it is normal to publicize it in a big way.
......
This interview was much shorter than the previous one. Even including makeup and additional shots, it took less than forty minutes in total.
Although the time is short, there is a lot of information in it.
In particular, the focus is on Chang Haonan’s glorious deeds, after learning about the flood, he made up his mind to license the patent to a manufacturer of flood control materials for free.
Of course, the fragments in this story are all true, and there is absolutely no fabrication.
It’s just that the order of occurrence has been slightly adjusted to highlight the high integrity of the interview subjects.
As a principled person, Chang Haonan still hopes to fully restore all the facts.
But then the other party insisted again and again, so he reluctantly agreed...
In addition, some other news was revealed during the interview.
For example, not only the front-line disaster relief officers and soldiers were full of praise for "Xi soil", but also the commander-in-chief of the entire river basin of this flood control mission also favored it.
After the soil was successfully used to fill the Buquan mouth of Gangneung Embankment, the latter not only asked each factory to quickly increase production, but even wrote the inscription himself.
And, in the phased report submitted above, a whole chapter was spent introducing the important role played by soil in flood prevention and rescue.
This is obviously huge good news for Chang Haonan, who has made up his mind to earn some influence for himself through this matter.
