The Military-industrial Scientific Research System of the Academic Master Chapter 390

Chapter 390 Two 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 release 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 historical process.

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 technical personnel responsible for the overall design of the software and module function writing are gathering together to listen to Sun Huizhong's report on the overall 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 a more complex aircraft design. Although the calculation amount is not necessarily higher than the former, it is 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, in order to obtain a true sense of These core-level factors can only account for at most half of its success.

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

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

Most of the members of Chang Haonan's project team are developers who major in computer science or applied mathematics and have little experience in the pain points of industrial software applications. However, Chang Haonan leads the entire development process and is too familiar with the software. It is so high that even if there is a problem, it is likely not to be experienced.

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, while the front is redesigned and uses the most cutting-edge DSI air inlet and nose retractable side strips to ensure that the angle of attack is 70°. Maneuverability within range…”

"The design points of the inlet are: the maximum Mach number Ma=1.3; the pre-compression bulge equivalent compression half-cone angle is 20°; the height is 11km and the capture area is determined based on this. When the engine is in the maximum state within the range of Ma=0.7-1.1Ma The flow rate determines the throat area, and the throat Mach number is controlled at Ma=0.5-0.7..."

"Considering that my own technical level is relatively limited, and that this model is improved from a mature and active model, I mainly used more traditional calculation methods throughout the design process, such as in the steady state of the whole machine. The improved surface element method is still used in the calculation of aerodynamic force. However, in the process of calculating the local convex hull curve of the DSI inlet, we still try to use the new nonlinear partial differential equations dimensionality reduction method provided in the software to calculate the N-S Equations are solved numerically…”

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.

However, 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.

Outside stood an administrative teacher from the supercomputing center.

“Director Chang, there is someone looking for you outside.”

Generally speaking, outsiders are not allowed to 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.

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...

It's okay not to talk about it.

So, just after he stood up and announced that the meeting would be suspended for a period of time, 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 when designing...”

The questions that kept ringing in his ears made Sun Huizhong's head feel as big as a bucket. Fortunately, before Chang Haonan left the venue, he didn't forget to queue up the engineers who were eager to ask questions about the modules they were involved in. This gave the former time to ask questions one by one. respond.

“Huh...So Director Chang faces this kind of scene after every meeting..."

Sun Huizhong, who finally breathed a sigh of relief, 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 he had not been contacted.

While thinking about this, he had already arrived at the reception room near the entrance on the first floor of the supercomputing center.

Several people are sitting inside. Chang Haonan actually knew one of the leaders -

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 members immediately stood up.

“For this meeting, I should call you 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, it turns out that not long after graduation, I have already started to hold leadership positions in the field of scientific research.

It's simply outrageous, no one can 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 a little used to this kind of scene, and knows that the best way to deal with it at the moment is to change the topic:

“I wonder how I can help this time?”

“I have received a request from above to conduct another exclusive interview with you. The topic is about the set of flood-fighting and disaster relief equipment you developed, so I have no choice but to come here to bother you one more time.”

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

Indeed, even in the entire history of central media, it is rare to interview the same person 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 the work done by Ding Gaoheng and Cao Gangchun.

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

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 advantage of the situation and sat opposite Ni Ping.

“You may have to appear on camera this time, so you should put on a 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 M60 project and aircraft anti-icing research, which had been used as shields before, have gradually failed to keep up with his progress.

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

Hence, 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.

Especially focused on the glorious deeds of Chang Haonan, who made up his mind to license the patent to a manufacturer of flood control materials for free after learning about the flood.

Of course, all the fragments in this story are 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.

However, 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 Paoquan mouth of Gangneung Embankment, the latter not only asked the factories to quickly increase production, but even wrote an inscription in his own hand.

Furthermore, in the phased report submitted above, a whole chapter was devoted to introducing the important role played by soil in flood relief.

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