Chapter 1176 I Want Them All

"Academician Chang?"

After a silence that lasted for several seconds, Jiang Zonglin asked in a confused tone:

"He doesn't seem to have any direct relationship with our field, right?"

He did know something about Chang Haonan, otherwise he wouldn't have been able to tell those analyzes just now.

But this is mainly due to the fact that the latter has been at the top of the domestic academic circle in the past two years, and it is inevitable that he will be mentioned in daily chats and gossips.

In fact, it is just normal attention to the big guys in the same industry.

Therefore, Jiang Zonglin quickly looked at Chen Hong with questioning eyes.

After all, the other party just claimed to have specifically investigated Chang Haonan's research route.

However, Chen Hong just shook his head in confusion, saying that he was not aware that Chang Haonan had previously been involved in the field of hypersonics or shock wave wind tunnels.

Although the others didn't say anything, judging from their expressions, they probably had similar thoughts.

Of course, it's a little embarrassing.

Although the incident just now was not a case of speaking ill of people behind their backs, it was still considered a case of using them as a weapon.

Now that the main character is approaching at the speed of light, there is always a sense of deja vu as if someone was talking behind someone's back only to be exposed in person.

Fortunately, at this time, Academician Yu stood up slowly:

"Anyway, I have to go pick up Academician Chang first, lest he can't find the door..."

The half-joking tone finally broke the slightly weird atmosphere of the scene.

As he spoke, he picked up his coat from the back of the chair and put it on with the help of the staff next to him.

In fact, he only knew at this moment that his superiors had assigned several companies and research institutions, including the Institute of Mechanics, Aerospace Science and Industry Group, and Aerospace Power Group, to jointly organize project demonstration and preliminary development of practical hypersonic vehicles. Pre-research.

As for the more specific situation, we have to wait for the formal documents to be issued.

Or wait and see what other news there is from Chang Haonan.

But in any case, as an essential infrastructure for hypersonic research, ultra-high-speed wind tunnels must be the top priority at this stage.

In terms of resources, it will probably not be as tight as in the past few years...

Upon seeing this, the rest of the people also stood up and prepared to go out to greet him.

After all, the visitor is an academician, so he must be given enough respect.

But Yu Hongru raised his hand to stop him:

"Just wait here."

"We don't know the specific confidentiality level of this matter yet, but I'm afraid the pomp outside is not suitable for making it too big..."

Everyone who can sit in this conference room is involved in highly sensitive projects.

Some of them are older and even came from the two-bomb and one-satellite projects.

So after listening to Yu Hongru's explanation, they all sat back silently.

It wasn't until Yu Hongru and the staff member left that some whispers resounded in the conference room.

As for the topic, of course it still revolves around Chang Haonan who suddenly appeared.

But soon, a voice came from an inconspicuous position at the end of the conference table:

"I suddenly remembered that Academician Chang did seem to have published a paper related to hypersonics before..."

Everyone's eyes converged almost instantly.

Among them, Chen Hong’s face was filled with disbelief:

"paper?"

He paused for a moment:

"Academician Chang's papers are not very numerous in total. I should have read them all..."

The person who just spoke was another proud disciple of Academician Yu Hongru and Jiang Zonglin's junior brother, Li **.

Because I just joined the Mechanics Institute a few years ago, I am a little transparent character most of the time.

Now that he suddenly became the focus of the entire conference room, he was a little uncomfortable.

"It was a paper written many years ago, and I only saw it accidentally..."

Although paper retrieval software like CNKI had appeared in China as early as the late 1990s, in 2005, its database was still quite imperfect.

Many papers, especially those from the last century, cannot be retrieved.

As Li ** spoke, he operated on the laptop in front of him.

Then turn it 180°:

"This is this article, published in 1996, "Research on the Integrated Layout of Dual-Module Mandibular Inward-Turn Inlet/Conical Front Body"..."

The computer screen was not big, and the distance between Chen Hong and Li ** was so far that it was difficult to see the specific content clearly.

But even if he only heard the title, he was sure that he had never seen it.

"1996..."

Chen Hong narrowed his eyes slightly:

"Academician Chang was born in 1976. He was only 20 years old at that time. If you do the math, he should still be in...his junior year?"

As soon as these words came out, the atmosphere in the entire conference room suddenly became a little tense.

First, it is too old. Except for a few fields, papers written ten years ago are actually difficult to provide any useful guidance for cutting-edge research.

Secondly...

Junior year is really a bit too young.

Engineering requires experience. Everyone knows that Chang Haonan's first serious participation in a project was from the end of 1996 to the beginning of 1997.

Therefore, few people paid special attention to the articles published before this.

It's no wonder that Chen Hong didn't know about this at all. Even Li **, after going through the summary and conclusion again, said with some helplessness:

"Well, this paper focuses on the transonic speed range... I just mentioned it at the end, saying that the same design method can be extended to a faster speed range, but after it exceeds five times the speed of sound, because It is difficult to reproduce actual flight conditions and the accuracy cannot be further guaranteed..."

However, this unintentional sentence made Jiang Zonglin and Chen Hong, who were sitting in front, shine at the same time.

Although the two had a fierce argument just now, their relationship was actually fine on weekdays.

The moment their eyes met, it was obvious that the other person was thinking of the same thing as him.

In the end, it was Jiang Zonglin who spoke first:

"The idea of ​​reproducing flight conditions was mentioned in 1996. It seems that Academician Chang has really been studying hypersonic issues since then..."

Others who were still in the dark suddenly woke up.

In fact, Chang Haonan had just been reborn that year, and most of his knowledge in his mind was related to the JF22 wind tunnel project in his previous life.

Therefore, when writing that paper, I almost instinctively wrote some proper terms that were not widely circulated at that time.

Strictly speaking, it should be considered a mistake.

However, looking back nearly ten years later, it turned out to be evidence that he was fully forward-looking.

There is a great Confucian who can argue for me.

…

Just as the discussion among everyone became heated again, a burst of chaotic footsteps came from the corridor outside.

It was also mixed with the loud laughter of Academician Yu Hongru.

Obviously, the rightful owner they had been discussing just now is already in place.

Sure enough, just a few seconds later, the two doors were opened by two staff members at the same time, and a group of people headed by Academician Yu appeared outside.

The obviously young person next to him was obviously Chang Haonan.

"Academician Chang, please go first."

"Please..."

After some polite greetings, the two entered the conference room one after another.

A dozen people around the table also stood up to show their welcome.

Fortunately, the conference table was wide enough, so Chang Haonan directly added a chair and sat next to Yu Hongru.

A layout of two first positions is formed.

As for the other people accompanying him, they were all Chang Haonan's security and entourage personnel and did not participate in this meeting.

After everyone sat down, Yu Hongru quickly returned to the topic:

"Academician Chang is here just in time. Two of our institute's most capable people were just discussing the next key development direction of ultra-high-speed wind tunnels..."

While introducing the situation, he motioned to Jiang Zonglin and Chen Hong on both sides of the conference table:

"Now, since the superiors want to develop a practical hypersonic aircraft, why not let you, the 'judge', guide our subsequent work?"

Although the superiors did not clarify in the verbal notification which unit the entire project will be based on, from the perspective of work development, the wind tunnel must be allowed to cooperate with the research and development of the aircraft, not the other way around.

Moreover, on the way just now, Yu Hongru had heard that his superiors made the above decision only after hearing Chang Haonan's report.

So for the sake of safety, he chose to show his weakness by joking first.

For Chang Haonan, sitting in the conference room of the Institute of Mechanics is like going home——

He had basically worked with the dozen or so people around this table in his previous life, and he knew the level of the entire team very well.

In fact, no specific business-level guidance is needed.

Just give a certain direction and theoretical basis.

"You can't do the job of guiding..."

He waved his hand and said humbly:

"On the way here, including some time ago, I have read many reports on the JF series of ultra-high-speed wind tunnels, as well as the papers of Researcher Jiang and Researcher Chen. I am still a novice in wind tunnel engineering. I need to learn a lot from you..."

However, after finishing the sentence, his tone suddenly became serious again:

“As for the hypersonic vehicle, my idea is to advance it in stages... firstly come up with an entry-level hypersonic weapon with a speed of around Mach 5 and using an axially symmetrical cone or bicone, and at the same time use relevant research to feed back into the aerospace field. We must actually prove the significance of our project to our superiors...

"So, the performance requirements for ultra-high-speed wind tunnels at this stage are that the airflow speed is 3-4km/s and the total temperature is not less than 4500-5000K... I know that you have a shock wave reflection technology that can solve the problem of forward The problem of severe attenuation of the incident shock wave from detonation makes the wind tunnel achieve this performance index..."

Hearing this, Jiang Zonglin's eyes gradually brightened.

This is exactly what he just advocated.

But almost immediately after, Chang Haonan changed the topic again:

"But in addition, in order to truly guide aircraft design, it is necessary to ensure a long enough experimental time, at least at the double-digit millisecond level. This can be achieved with the help of starting shock wave reflection control technology and shock wave/ Boundary layer pollution suppression technology to achieve..."

"In addition, the wind tunnel needs to be able to reproduce the test data with relatively high accuracy. This requires the multi-fundamental interference wave system adaptation algorithm proposed by Researcher Chen. As for the hardware level... I can solve the problem of high-sensitivity new thermoelectrics through special channels. Of course, in the long run, it is more reliable to realize localization of supply..."

"..."

The corners of Chen Hong's mouth also curved...

However, Yu Hongru gradually felt something was wrong——

From what he said, it's clear that he wants to have it all.

Of course, when there are resources in the future, this is understandable.

The key issue is...

How come this Academician Chang seems to know more about the research of the Institute of Mechanics than we do?
