Chapter 1203 Power is not a problem

Of course Li Zhongyi heard what Chang Haonan said.

But he suddenly felt a little dazed.

So much so that I forgot to react for a moment.

For a moment, Li Zhongyi even felt as if he had returned to his student days decades ago.

The clearly organized table in front of you is the key point that the teacher has drawn for everyone before the final exam.

Even after you know the key points, you still have to learn them, and you may not be able to learn them immediately.

But as long as you use this as an outline for review, then at least in the direction, you will definitely be right.

After the trance, Li Zhongyi lowered his head again and scanned the 80 technical items densely written on the paper.

This time, I looked at it with a critical and analytical eye.

“This list…means a lot.”

He took a deep breath and said in a serious tone:

"We will organize research as soon as possible and come up with a practical research plan to ensure the smooth development of the fourth-generation aircraft engine!"

When he opened his mouth this time, Li Zhongyi even felt a little more pressure on his back.

He doesn't know much about aerospace, but there are always some similarities between science and engineering.

Technologies like "wear-resistant and high-temperature resistant ceramic coating" or "full three-dimensional design for non-steady adhesion" are not difficult to find application scenarios in other fields, even from the perspective of an engineer with a background in the petroleum system.

In other words, the value of this list is not just to provide China's aerospace industry with development direction for at least the next twenty years.

It even has a considerable driving effect on the development of the entire industry.

Li Zhongyi had only heard of this kind of scene from his predecessors in the past.

When the country was first established, everything was in ruins...

However, the Industrial Construction Commission is not the National Defense Science and Technology Commission that literally controlled everything back then. Many things today can no longer be implemented by simple administrative orders, but can only be encouraged by resource and policy tilts.

This really tests your working methods and approaches.

If it is just a simple investment of money, then many government offices that have been doing nothing for a long time may have negative effects when they suddenly obtain a large amount of resources at their disposal...

Chang Haonan, who was leaning against the window, looked at Li Zhongyi, whose expression was mixed with joy and worry. It was not difficult to guess that the other party was probably thinking about specific implementation issues.

However, he is only a consultant to the Construction Committee. It is better to leave such administrative matters to professionals...

"Then Director Li, I'll leave the following matters to you."

Chang Haonan didn't plan to continue wasting time here, so he went back to the sofa, picked up his coat and briefcase and prepared to leave.

"Um……"

Li Zhongyi hadn't recovered from his thoughts yet. He nodded subconsciously, but then he called out to Chang Haonan, who had already turned around:

"Wait a minute... I was just shocked by your list of eighty items and almost forgot."

He stood up and searched on the bookshelf behind him for a while.

Finally take out a file box:

"Although you have been well prepared, this is a summary of the situation that the Aviation Industry Corporation handed over a few days ago. I should still show it to you before the meeting..."

……

Although the domestic fourth-generation fighter project has never been officially launched, the preliminary research work has been carried out for more than ten years, so even after refinement, the summarized content is not small.

Chang Haonan spent four days reading it all, and then went to the meeting with a PPT of only two pages.

Because it is still a long way from entering the formal project approval process, this meeting, although of a high standard, is not particularly solemn and serious in form.

Overall, it is a bit like the aviation engine industry conference held by Chang Haonan eight years ago.

However, the aero-engine industry at that time only had the WS-10, and Chang Haonan, as the biggest contributor to the revitalization of the WP-14, can almost be said to have the final say.

As for the fourth-generation fighter jets, all the main manufacturers have been preparing for many years, and no one can easily give up this initiative.

So, even before the event officially started, the scene was still quite harmonious.

But the smell of gunpowder in the air was something that everyone could feel.

In fact, Chang Haonan got up very early that day and arrived at the venue nearly an hour in advance.

But when I glanced at the name tags on the tables in the first few rows at the door, I realized that many of the people present today were my acquaintances.

If you enter too early, you will inevitably be dragged into the conversation for a long time.

If it's just normal private communication between acquaintances, then there's no problem.

But in the eyes of others, the time you spend interacting with representatives of each factory, the expressions you show and other details will inevitably become signals of expressing support or opposition.

If this affects the final result, it would be bad.

Just as he was hesitating, Song Jiaxiang followed him from behind.

After a few pleasantries, he pulled him aside and said in a somewhat sneaky way:

"Academician Chang, the venue is still being set up. Could you please go to the lounge next door to rest for a while... and then come in when the meeting is about to start?"

That being said, it was not difficult for Chang Haonan to see that the other party was worried about the same thing as himself.

"It seems that being too famous is not necessarily a good thing sometimes..."

He silently sighed in his heart that people in the world have no choice but to do what they want, and then walked to the next door with Song Jiaxiang.

It was not until three minutes before the meeting started that he pretended to have arrived in a hurry and appeared in the special guest seat carrying a briefcase.

As expected, a number of his old buddies like Sun Cong, Yang Wei, and Sun Huizhong's eyes lit up almost at the same time, and some of them even wanted to stand up directly.

He just looked at the leaders sitting on the podium and saw that the meeting was about to begin before he finally gave up.

"...First of all, it is the efforts made by all comrades that have enabled us to hold this meeting today. On behalf of the group leaders, I would like to express my respect and gratitude to you all..."

Song Jiaxiang, who presided over the meeting, gave a brief opening speech, which drew applause from the audience.

He raised one hand and pressed it down slightly, and the meeting room soon returned to silence:

"All the people attending the meeting today are from our technical field, so I won't go into too much detail. Next, Comrade Lü Guang from the Air Force Equipment Research Institute will introduce to you the analysis and requirements of the aviation force for the performance elements of the fourth-generation fighter..."

"..."

In fact, what Lu Guang said was similar to what Song Jiaxiang had summarized and refined before, which was to rank the typical performance that the fourth-generation fighter should have according to their importance.

Of course, there will definitely be more specific needs at the user level.

But it needs to be put aside for subsequent discussions or even the project establishment stage.

Now these are the basic principles that provide a safety net.

For example, the Air Force has made it clear that it focuses on forward stealth and supersonic performance.

Then you certainly can't come up with an abstract plan with forward-swept wings or half-buried missiles.

In fact, most people inside the Aviation Industry Corporation of China already knew almost everything in advance, and now they are just confirming it again in a formal occasion.

However, Chang Haonan listened with great interest.

Although the Air Force also participated in the selection in 07, it was essentially dominated by the developers.

Now, users have clearly put forward specific indicators such as "when facing enemy airborne radar in the front hemisphere, the detection and locking distance is shortened by more than three quarters compared with existing models."

Therefore, the plans that are brought to the table for discussion may be somewhat different.

Putting aside the plan that eventually developed into the J-20, at least the three-wing route of 601 was definitely not feasible from the beginning.

What's more, China's current technological accumulation in the aviation industry is far from comparable to the original timeline.

Thinking of this, Chang Haonan lowered his head slightly and looked at the PPT on his computer desktop——

The content there might add fuel to the intensity of this meeting...

According to the agenda, after Lu Guang's introduction, it will be Chang Haonan's turn to speak.

After all, there are many design options for the aircraft itself.

But this is the only kind of power that can be used.

It must be a known condition so that everyone can have an idea of ​​it first.

"Almost all of you have participated in the development of the third-generation fighter jets, so I won't keep you in suspense."

When Chang Haonan opened the PPT, some sharp-eyed people noticed that the thumbnails on the left actually only had two pages.

"In response to the basic technical requirements just raised by Comrade Lü Guang, I have summarized the power plant of the fourth-generation fighter into four 'properties' and three 'capabilities'."

He then opened the first page of the PPT:

"The first is technological advancement, that is, large unit thrust, with a thrust-to-weight ratio of 10; the second is structural simplicity, with a small number of structural parts in the whole machine, which is easy to produce and repair; the third is durability, with full consideration of reliability and long service life in the design of parts and the whole machine, and the plan is to make the first overhaul time exceed 2500 hours; the fourth is maintainability, reducing the number of necessary maintenance times, personnel and working hours required..."

"The three capabilities refer to optimizing the supersonic thrust curve to enable the aircraft to obtain supersonic cruise capability, strengthening the tail infrared stealth and front radar stealth capabilities, and cooperating with flight control research and development units to achieve vector thrust capability..."

Chang Haonan raised his head and slowly glanced at the participants in front of him:

"This time, I can make a very firm guarantee that, starting from the program selection stage, there is no need to compromise on the aircraft's power level as in the past."

"So, please give your best performance!"
