Chapter 1202 List of Eighty Technologies

"Before the end of August..."

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

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

"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 the situation of other units still needs to be connected... Especially the Aviation Power Group, Academician Chang himself must be invited."

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

Therefore, he naturally became one of the candidates that the Aviation Power Group must send a letter to invite.

But Zhang Hongbiao waved his hand:

"Director Li has already contacted Academician Chang in person, and 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 to the beginning of 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 doesn't know much about this matter.

He only thinks that the main work in Gaojing is the high bypass ratio turbofan engine.

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

Song Jiaxiang answered while marking the calendar at the front of his notebook.

Zhang Hongbiao continued to add:

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

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

But Song Jiaxiang showed hesitation.

Zhang Hongbiao is not a professional in aviation. Although he has learned a lot over the years, he relies heavily on the opinions of expert consultants and rarely guides experts.

But when it comes to some details, it is still a little bit off.

So after thinking it over again and again, he still spoke:

"In fact, Director Zhang, when Academician Chang designed the WS-10 many years ago, he had considered the power requirements of the new generation of fighters. At that time, it was made according to the foundation of the fourth-generation engine, so we estimate that Academician Chang should have 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 before is not completely related to power. Among the several plans submitted before, there are actually some that tend to optimize 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 plans for adaptation and adjustment..."

These words actually carry Zhang Hongbiao's considerations both in public and private.

In public, the Aviation Industry Corporation of China has not been taking resources for nothing in recent years. Through the two projects of J-10 and J-11, it has already had a considerable understanding of the design and production of fighters of different sizes.

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

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

...

As Zhang Hongbiao said, Chang Haonan actually received a call from Li Zhongyi before the meeting of the Aviation Industry Group.

In fact, he was not deeply involved in this matter, and only sent a letter to several comrades in the Air Force Equipment Research Institute in the middle.

To be honest, the result he got now even exceeded his initial expectations.

But what surprised him even more was that his superiors would make such a fierce and clear reaction.

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

I think it's because after the timeline changed, there were no series of events that happened in the middle, and the power comparison between the two sides was not as disparate as in the previous life, which led to some changes in the struggle strategy of the decision-making level.

In short,...

If there is no other way, who would be willing to be a turtle?

Fortunately, Chang Haonan was prepared for this.

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

Therefore, he will not feel any panic because of two years in advance.

After receiving the call, Chang Haonan simply arranged 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 couldn't wait to get to the point:

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

"What surprises us... and of course what makes us happy is that several host research institutes have made a lot of preparations for the overall design. However, they have not been able to reach a consensus because of the lack of specific requirements and evaluations. Now we have According to the clear opinions of the Air Force, a program seminar is expected to be held early next month to determine the feasibility and technical route of research and development.”

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

"However, aircraft research and development cannot be carried out without your aviation power group, so... today, on the one hand, I want to listen to your opinions and of course your requirements. On the other hand, I also invite you to attend this program seminar."

At this time, the latter noticed that the envelope had the logo of the Aviation Industry Group printed on the surface, and inside it should be an invitation and a certificate of attendance.

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

Now that he had this opportunity, even if it was just out of curiosity, he hoped to participate in it personally.

Therefore, Chang Haonan immediately put the envelope into his briefcase, which was regarded as complying with the second thing Li Zhongyi said just now.

As for the first one...

"Regarding the fourth-generation engine, I think you should know that I have been preparing for it since the launch of the Turbofan 10 project."

Chang Haonan took out a folder slowly:

"Actually, when I came back this time, what I prepared was not an engine model... but an aerospace engine industry plan for the next twenty years!"

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

"this……"

The latter was shocked and subconsciously lowered his head, only to find that there was only one piece of paper in the folder.

Or rather, a form.

"This table is what I have listed, the 80 key technologies needed to develop future aero engines. The 40 items on the left are fourth-generation engines, which will be used in the last five years, and the 40 items on the right are The fifth-generation engine may be used in 10-15 years.”

Chang Haonan did not wait for Li Zhongyi to recover from the shock. He walked slowly to the window, looked at the rows of tall 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 about ten items still require the Industrial and Construction Committee to pool national resources in order to Make progress soon!"
