Chapter 1203 Motivation is not a problem
Of course Li Zhongyi heard what Chang Haonan said.
However, he suddenly felt a little dazed.
So much so that I forgot to react for a while.
For a moment, Li Zhongyi even felt as if he had returned to his student days decades ago.
The clearly organized form in front of you is the key point that the teacher drew for everyone before the final exam.
Although you know the key points, you still have to learn them, and you may not be able to learn them right away.
But as long as you review this as an outline, you will definitely not go wrong, at least in the direction.
After the trance, Li Zhongyi lowered his head again and glanced at the 80 technical items densely written on the paper.
This time, I looked at it with a critical and analytical eye.
"This list... is of great significance."
He took a deep breath slowly 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 progress of the development of the fourth-generation aeroengine!”
When he spoke this time, Li Zhongyi even felt a little more pressure on his back.
He doesn’t know much about aerospace, but there are some similarities between science and engineering.
For technologies such as "wear-resistant and high-temperature-resistant ceramic coating" or "unsteady and sticky full three-dimensional design", even from the perspective of an engineer with a background in petroleum systems, it is not difficult to find application scenarios in other fields.
In other words, the value of this list is not only to provide the development direction for China's aerospace industry for at least the next twenty years.
It even plays a considerable role in promoting the development of the entire industry.
Li Zhongyi had only heard of this kind of scene from his predecessors in the past -
In the early days of the founding of the People's Republic of China, when everything was in ruins and waiting for prosperity...
But after all, the Industrial and Construction Commission is not the National Defense Science and Technology Commission that literally governed everything back then. Nowadays, many things cannot be implemented by simple administrative orders and can only be encouraged by resources and policy preferences.
This is a test of the way you work.
If you just throw money at it, then many long-standing Qingshui Yamen will suddenly have a massive amount of resources at their disposal, which may have negative effects...
Chang Haonan leaning against the window Looking at Li Zhongyi, who had a mixed look on his face, it was not difficult to guess that the other party was probably thinking about specific implementation issues.
But he is only a consultant to the Industrial and Construction Committee. It is better to leave this administrative matter to professionals...
"Then Director Li, I'll leave the following matters to you to worry about."
Chang Haonan was not going to continue to waste time here, so he returned to the sofa, picked up his coat and briefcase and prepared to leave .
"Well..."
Li Zhongyi had not yet fully recovered from his thoughts. He nodded subconsciously, but immediately called out to Chang Haonan who had already turned around:
"Wait a minute...I was so shocked by your eighty-item list just now that I almost forgot."
As he spoke, he stood up and rummaged through the bookshelf behind him for a while.
Finally took out a file box:
"Although you have been fully prepared, this is a summary of the situation submitted by the Aviation Industry Group a few days ago. It should still be in Let me show it to you before the meeting..."
...
Although the domestic fourth-generation fighter jet has not been officially approved, the pre-research work has been carried out for more than ten years, so Even after refining, the summed up content is not too 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 far from entering the formal project approval process, although this meeting is of high standard, it is not particularly solemn in form.
In general, it is a bit like the aerospace industry conference held by Chang Haonan eight years ago.
However, at that time, the aerospace industry only had a single seedling of the turbofan 10. As the biggest contributor to the revitalization of the turbojet 14, Chang Haonan can almost be said to be unparalleled.
As for the fourth-generation fighter jets, all OEMs have been preparing for many years, and no one can give up this initiative easily.
Therefore, although before the official start, the scene was still harmonious.
But anyone can feel the smell of gunpowder in the air.
Actually, Chang Haonan got up very early that day and arrived at the venue nearly an hour early.
But when I looked at the name tags on the tables in the first few rows at the door, I realized that many of the people attending today were my acquaintances.
If you enter the venue too early, you will inevitably be dragged into chatting for a long time.
If it's just a normal private communication between acquaintances, that's fine.
But in the eyes of others, the time spent in contact with each factory representative, as well as the demeanor and other details, will inevitably become signals of support or opposition. If this affects the final result, that would be a bit bad.
Just when he was hesitating, Song Jiaxiang also followed from behind.
After a few words of greeting, he pulled him aside and said with a bit of sneakiness:
"Academician Chang, the venue is still being decorated. Could you please go to the lounge next door to rest for a while...and then enter the venue when the meeting is about to start?"
That's what Chang Haonan said, but Chang Haonan It is not difficult to see that the other person is actually worried about the same things as himself.
"It seems that being too famous may not be a good thing sometimes..."
He silently lamented in his heart that people can't help themselves in the world, and then walked next door with Song Jiaxiang .
It was not until three minutes before the meeting started that he deliberately pretended to be in a hurry and appeared at the special guest seat with his briefcase in hand.
As expected, all the old guys who were familiar with him, such as Sun Cong, Yang Wei, Sun Huizhong, etc., their eyes lit up almost at the same time, and some of them even wanted to get up immediately.
I just gave up after looking at the leaders sitting on the podium and the meeting time that was about to start.
“...First of all, it is the hard work that all comrades have put in so that we have the conditions to hold this meeting today. On behalf of the group leaders, I would like to express my respect and gratitude to everyone..."
< br>Song Jiaxiang, who presided over the meeting, made a simple opening statement, which attracted a burst of applause from the audience.
He raised one hand and pressed it down slightly, and the venue quickly returned to silence:
"The people attending the meeting today are all our technical experts, so I won't go into too much red tape. Next, Comrade Lu Guang from the Air Force Equipment Research Institute will introduce to you the aviation force's requirements for the performance factors of fourth-generation fighter jets. Analysis and needs..."
"..."
In fact, what Lu Guang said is similar to what Song Jiaxiang summarized and refined before, which is what the fourth-generation fighter should have The typical performances of are arranged in order of importance.
Of course, there will definitely be more specific needs at the user level.
But it needs to be left to subsequent discussions and even the project establishment stage.
Now these are basic principles.
For example, the Air Force has made it clear that it focuses on forward stealth capabilities and supersonic performance.
Then you definitely can’t come up with an abstract plan of forward-swept wings or half-buried bombs.
In fact, most of the people within the Aviation Industry Group already knew everything in advance, and now they just confirmed it again on a formal occasion.
But Chang Haonan listened with great interest.
Although the Air Force was also involved in the selection in 2007 in the previous life, it was essentially led by the developer.
Now, users have clearly put forward specific indicators such as "When facing enemy airborne radar in the front hemisphere, the distance between detection and locking is shortened by more than three-quarters compared to existing models."
So there may be some differences among the plans that are put on the table for discussion.
Let’s not mention the plan that was eventually developed into the J-20. At least the three-wing route of the 601 was definitely unworkable 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 may add 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 there is only one kind of power that can be used.
It must be regarded as a known condition, so that everyone can figure it out first.
“Almost all of you have participated in the research and development of third-generation fighter jets, so I won’t say too much about it.”
When Chang Haonan opened the PPT, some sharp-eyed people had already noticed, The thumbnail on the left is actually only two pages.
"In view of the basic technical requirements put forward by Comrade Lu Guang just now, I summarize the power plant of the fourth-generation fighter into four' characteristics and three' capabilities."
He said and opened the third chapter One page PPT:
"The first is technological advancement, that is, the unit thrust is large, and the thrust-to-weight ratio is at level 10; the second is the simplicity of the structure, with fewer parts in the entire machine structure, making it easy to produce and maintain; the third is durability, from the design of parts to the complete machine Taking full consideration of reliability and long service life, the design It is planned to allow the first overhaul time to exceed the 2,500-hour mark; the fourth is maintainability, reducing the number of necessary maintenance times, personnel and working hours..."
"The third capability refers to optimizing the supersonic thrust curve to allow Aircraft gains supersonic cruise capability , strengthen the tail infrared stealth and frontal radar stealth capabilities, and cooperate with the flight control research and development unit to achieve vector thrust capability..."
Chang Haonan raised his head and slowly glanced at the attendees in front of him:
“This time , I can guarantee with great certainty that starting from the plan selection stage, there is no need to compromise for the power level of the aircraft as in the past.”
“So, please give your best. Strong level! ”
