Chapter 1202 8 Technology List

"Before the end of August..."

Zhang Hongbiao muttered something softly, then raised his head slightly, thought about his schedule for next month, and tried to see how he could catch up with this exchange seminar.

But as the second-in-command of the department in charge of the national industrial construction and development, his schedule is indeed quite busy:

"Can't you determine a more accurate time now?"

Song Jiaxiang hesitated for a moment, then shook his head:

"Of course there is no problem with our own people, but we still need to connect with other units...especially the Aviation Power Group, Academician Chang himself must be invited."

At this point, it is almost impossible to avoid the name Chang Haonan in the aviation industry if you want to launch new projects, especially new large projects.

Therefore, he naturally became one of the candidates that Aviation Power Group had to send an invitation letter to.

But Zhang Hongbiao waved his hand:

"Director Li has already contacted Academician Chang personally. He will probably be back from Gaojing in two days."

He tapped the table lightly to emphasize:

"If you consider his schedule, then you'd better arrange it until early August so that Academician Chang can return to Beijing once and get everything done. Now is the critical stage of the WS-20 test, and the work in Gaojing is also very intense."

In fact, compared with the WS-20, Chang Haonan is currently more busy with hypersonic weapons.

But let alone Song Jiaxiang, even Zhang Hongbiao didn't know much about this matter.

I just thought that the main work in Gaojing was on the high bypass ratio turbofan engine.

"If that's the case, we'll try to schedule the meeting in the first week of August..."

As Song Jiaxiang answered, he made a mark on the calendar at the front of his notebook.

Zhang Hongbiao then added:

"In addition, your group leaders should communicate with the subordinate host research institutes in advance to summarize the requirements for the power unit of the fourth-generation fighter. Just use the analysis just now as a template. It will also be convenient for Academician Chang and others to make a reference. Try to make the power unit and the aircraft developed and mature at the same time as the J-10."

In fact, when he said this, he was already preparing to end the story.

But Song Jiaxiang looked hesitant.

Zhang Hongbiao is not a professional aviation person, although he has learned a lot over the years and relies heavily on the opinions of expert consultants, and it is rare for a layman to guide an expert.

But when it comes to some details, it's still a little lacking.

So after thinking it over again and again, he finally said:

"In fact, Director Zhang, when Academician Chang designed the WS-10 many years ago, he considered the power requirements of the new generation of fighter jets. At that time, he designed it based on the foundation of the fourth-generation engine. So we estimate that Academician Chang should have had his own plan."

"In addition, the power requirements of the fourth-generation aircraft plan are not as strict as imagined... For example, the supersonic cruise capability mentioned earlier is not entirely related to power. Among the several proposals submitted before, there are actually some that tend to be optimized for low resistance, and even the current WS-10B can achieve supercruise..."

"In short, the design and selection work itself is related to the performance of the target power. No matter what level of fourth-generation engine Academician Chang comes up with, we can have corresponding solutions for adaptation and adjustment..."

These words actually reflect Zhang Hongbiao's considerations on both public and private aspects.

From a public perspective, the Aviation Industry Corporation of China has not been using resources for free over the years. Through the J-10 and J-11 projects, it has already gained a considerable understanding of the design and production of fighter jets of different sizes.

Today's aircraft design is no longer limited to the choice of "aerodynamic adaptation around a specific model of power" or "power adaptation around a specific aerodynamic design", but should be a combination of aerodynamics and power, external flow and internal flow.

Personally, perhaps Chang Haonan does have the ability to provide a guarantee for the entire project, but as a newly appointed group leader, he does not want to leave an impression on his superiors that "nothing can be done without outsiders."

……

Just as Zhang Hongbiao said, Chang Haonan had actually received a call from Li Zhongyi before the meeting at the Aviation Industry Corporation of China.

In fact, he was not deeply involved in this matter. He just wrote a letter to several comrades from the Air Force Equipment Research Institute.

To be honest, the results today have even exceeded his initial expectations.

But what surprised him even more was that his superiors would react so fiercely and clearly.

You know, the selection and project of the fourth-generation fighter jet in the previous life was around before 2008, and this wave was directly advanced by almost two years.

I think it is because after the timeline changed, the series of events that happened in the middle disappeared, and the balance of power between the two sides was not as great as in the previous life, which led to certain changes in the struggle strategy of the decision-makers.

To put it simply...

If there is no other way, who the hell would want to be a turtle?

Fortunately, Chang Haonan was well prepared for this.

Or rather, he had been preparing for this day since the first day of his rebirth.

Therefore, there is no need to feel any panic because of the two years in advance.

After receiving the call, Chang Haonan made some simple arrangements for the work in Gaojing, and then flew back to Beijing as quickly as possible...

"Academician Chang, I'm sorry to call you back from Gaojing in such a hurry."

As soon as they met, Li Zhongyi could hardly wait to get to the point:

"However, our superiors attach great importance to this matter. Just the day before yesterday, Deputy Director Zhang personally went to the Aviation Industry Corporation of China to hold a symposium and listen to the opinions of their leadership team members."

"We are quite surprised... but also quite happy that several host research institutes have already made a lot of preparations for the overall design. It was only due to the lack of specific requirements and evaluation that we were unable to reach a consensus. Now that we have the clear opinion from the Air Force, we expect to hold a program seminar at the beginning of next month to determine the feasibility and technical route of research and development."

As he spoke, he picked up a meeting minutes and an envelope from the table and handed them to Chang Haonan.

"However, aircraft research and development cannot be done without your Aviation Power Group, so... today, on the one hand, I want to listen to your opinions and of course make some requests, and on the other hand, I want to invite you to attend this program seminar."

It was at this time that the latter noticed that the envelope had the logo of Aviation Industry Corporation of China printed on its surface, and that it should contain a set of things such as an invitation and an attendance certificate.

In fact, Chang Haonan had heard about the selection process of the fourth-generation fighter jets in his previous life.

Now that there is this opportunity, even if it is just out of curiosity, he hopes to participate in it personally.

So, Chang Haonan immediately put the envelope into his briefcase, which was considered as agreeing to the second thing Li Zhongyi had just mentioned.

As for the first one...

"Regarding the fourth-generation engine, I think you should know that I have been preparing since the WS-10 project was launched."

Chang Haonan took out a folder slowly:

"In fact, what I came back with this time was not an engine model...but a plan for the aviation engine industry in the next 20 years!"

As he spoke, he had already opened the folder, turned it 180 degrees and placed it in front of Li Zhongyi.

"This……"

The latter was so shocked that he subconsciously looked down and found that there was only a piece of paper in the folder.

Or rather, a form.

"This table lists the 80 key technologies needed to develop future aircraft engines. The 40 on the left are for fourth-generation engines, which will be needed in the next five years, and the 5 on the right are for fifth-generation engines, which may be used in 40-10 years."

Chang Haonan did not wait for Li Zhongyi to recover from his shock. He slowly walked to the window, looked at the high-rise buildings outside and said:

"Of course, some of them, especially a large part of the first 40 items, have been solved by us or other units... But Director Li, the remaining ten or so items still require the Industry and Construction Commission to concentrate national resources in order to make progress as soon as possible!"
