Since the nationwide flood fighting and rescue operation at the organizational level is still ongoing, according to the process, it is indeed not time to come out of the settlement screen, so Chang Haonan can only temporarily collude with the two leaders today.

As for how much can be gained in the future, it is not only a matter of personal efforts, but also the course of history.

However, the efficiency shown by Ding Gaoheng and Cao Gangchun in this matter is indeed quite amazing.

Two days later, the supercomputing center of Jinghang University.

Chang Haonan and several other core technicians responsible for the overall design of the software and the compilation of module functions are gathering together to listen to Sun Huizhong's report on the overall situation of the aerodynamic design optimization of the new advanced training aircraft.

Compared with the previous project of Professor Rui Xiaoting of Jinling University of Science and Technology to do the overall system dynamics analysis of long-range rocket artillery, what Guihang is doing is a more complex aircraft design after all, although it may not be higher in terms of calculation amount, but the advantage is that they are basically applied to almost all the functions of the software design at this stage.

And the trial version is closer to the upcoming "public beta" for users.

Although under the management and supervision of Chang Haonan, there will certainly be no major problems in the core numerical calculation methods and operation logic of this set of things, but as a software, a user-oriented commercial software, in order to achieve real success, these kernel-level factors can only account for half at most.

The other half is the user experience level such as human-computer interaction, I/O design, and compatibility.

This is also the part that the system is completely unable to handle.

The vast majority of the members of Chang Haonan's project team are developers who are biased towards computer science or applied mathematics majors, and do not have deep experience in the pain points of industrial software applications, while Chang Haonan leads the entire development process and is too familiar with the software, so that even if there is a problem, it is likely that it will not be experienced.

It's like writing a paper, even if the author himself checks it ten times and then hands it over to another person, he or she 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 sat down for the first time, opening a small notebook and taking notes.

When he first started speaking, the former's tone even trembled a little with excitement.

After all, there aren't many opportunities to give lectures to big guys like this.

"Let me first introduce the overall design process of this type of aircraft, as well as the key technical specifications......"

"Compared with the J-7F aircraft, the structure after the 5845mm position remains the same, and the front is redesigned, using the current cutting-edge DSI air inlet and nose retractable side strips, which can ensure maneuverability in the range of 70 ° angle of attack......"

"The design point of the inlet tract is: the maximum Mach number Ma=1.3, and the equivalent compression half-cone angle of the pre-compression drum is 20°; The height is 11 km and the capture area is determined by this, and the throat area is determined according to the flow rate at the maximum state of the engine in the range of Ma=0.7-1.1Ma, and the Mach number of the throat is controlled at Ma=0.5-0.7......."

"Considering that my own technical level is relatively limited, and this model is still improved from the mature active model after all, I mainly use more traditional calculation methods in the whole design process, such as the improved surface element method is still used in the calculation of the stationary aerodynamic force of the whole machine, but in the process of calculating the local convex hull profile curve of the DSI inlet, I still try to use the new nonlinear partial differential equation system system dimensionality reduction method provided in the software to solve the N-S equation numerically......"

With the introduction of Sun Huizhong on the stage, several people below, especially those who have participated in some practical projects, have begun to write hard, for a while, in addition to the sound of the former's speech, there is only the occasional notebook page turning or the sound of keyboard tapping when typing.

Due to the lack of experience in reporting on stage, Sun Huizhong's introduction was somewhat unprioritized, so it took a lot longer than expected.

But in the end, he finally told everyone what they wanted to hear.

Just as Sun Huizhong was already preparing to wrap up, there was a sudden knock on the door of the conference room.

Outside, there was a teacher in charge of administration at the supercomputing center.

"Director Chang, someone is looking for you outside."

Generally speaking, outsiders are not allowed to enter the computer room area without permission, so someone needs to report it.

And to get the other party to come in directly in this kind of meeting, obviously it can't be just someone.

I'll have to go down and have a look.

Fortunately, the really valuable content of the whole report has been completed, as for the closing part......

Don't talk about it.

So, just after he got up and announced that the meeting was suspended for a while, Sun Huizhong on the stage was almost instantly surrounded by several people who had been eager to try it from the beginning.

"Sun Gong, do you think there is anything that needs to be improved in the user interface of our software......

"Do you think the new fully automated meshing method is useful......

"Is the technical instruction manual that comes with the software ......comprehensive?"

Which multi-objective optimization strategy did you choose during the design......

Fortunately, Chang Haonan did not forget to let these engineers who were anxious to ask questions about the modules they were involved in line before leaving the venue, so that the former had time to respond to questions one by one.

"Whew...... It turns out that Director Chang is faced with this kind of scene after every meeting......

Sun Huizhong, who finally breathed a sigh of relief, thought so.

On the other side, Chang Haonan, who was leaving the conference room, took out his mobile phone from his pocket and took a look.

Unsurprisingly, there were several missed calls.

He muted up the sound during the meeting and didn't pick it up.

It seems that the other party has never contacted him, so he had to come directly to the door.

Thinking like this, he had already arrived at the reception room located near the entrance of the first floor of the supercomputing center.

There were a few people sitting inside.

The first one, Chang Haonan even knows-

It was the CCTV hostess who came to Beijing Airlines to do an exclusive interview with him just after he won the May Fourth Medal of Chinese Youth a few months ago.

Seeing Chang Haonan walking in from the door, several people on the other side also stood up.

"This meeting, I should call Director Chang, good afternoon."

The two shook hands.

Even though Ni Ping is experienced and prepared, when he really faces Chang Haonan again, he can't help but sigh in his heart.

Others may not know the real age of the latter, but she is clear.

After all, just three months ago, the identity of the other party was still an undergraduate student of Beijing Airlines University.

Now that I have just graduated, I have already begun to take on a leadership position in the field of scientific research.

It's outrageous, I didn't go so fast on a rocket.

"Ms. Ni, I haven't seen you for a few months, but you are still shining."

Chang Haonan is now a little more accustomed to this kind of scene, and knows that the best way to deal with it at the moment is to divert the topic:

"I wonder if there's anything I can do to help this time?"

"I received the above request to give you another interview, the theme is about the set of flood relief equipment you developed, so I have to come and bother again."

Ni Ping added an accent to the word "again".

Indeed, even in the entire history of the central media, it is rare to give the same person two interviews in three months, and it is because of completely different things.

Although Chang Haonan's contribution this time is indeed not small, even the official publicity can be arranged so quickly, I am afraid it is inseparable from some of the work done by Ding Gaoheng and Cao Gangchun.

For Chang Haonan, who has already had a similar experience, doing interviews is already familiar.

And facing the camera again, he didn't have the tension he had at the beginning.

"So let's get started?"

Chang Haonan took the opportunity to sit opposite Ni Ping.

"You may have to be on camera this time, so you need to put on makeup simply, otherwise your face will be dark."

The latter then called in the makeup artist who accompanied him.

With Chang Haonan's position and the resources he can mobilize more and more, his existence as a person must not be hidden.

And the MA 60 project, which has been used as a shield, and the anti-icing research of the aircraft, which have gradually failed to keep up with his progress.

And it just so happens that his contribution to the flood relief process this time perfectly meets the requirements of being a "public reason for promotion": the influence is large enough, the research content is not sensitive, and the number of people who know the inside story is very small.

Therefore, it is normal to publicize a wave of special books.

……

This interview was much shorter than the previous one, and even if you count the makeup and back-up shots, it took less than 40 minutes in total.

Although the time is short, there is a lot of information in it.

In particular, it focuses on the glorious deeds of Chang Haonan who resolutely made up his mind to grant the patent to the flood control material manufacturer free of charge after learning of the flood.

Of course, all the fragments in this story are true, and there is no nonsense.

It's just that the order of occurrence has been slightly adjusted to highlight the high profile of the interviewee.

As a principled person, Chang Haonan still hopes to completely restore all the facts.

But then the other party insisted repeatedly, and he had to reluctantly agree......

In addition to this, some other information was revealed during the interview.

For example, not only the front-line disaster relief commanders and fighters are full of praise for the "rest of the soil", but even the commander-in-chief of the whole river basin of this flood control mission is also very favored.

After the soil was successfully used to fill the mouth of the spring at the Gangneung Embankment, the latter not only asked the factories to quickly increase production, but even wrote an inscription in their own handwriting.

In addition, in the interim report submitted above, an entire chapter is devoted to the important role played by the soil in flood fighting and rescue.

This is obviously great news for Chang Haonan, who has made up his mind to earn an influence for himself through this matter.
