Chapter 1202 List of Eighty Technologies


    "Before the end of August..."


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


    But as the second-in-command in the department responsible for the development of industrial construction across the country, his schedule is indeed quite intensive:


    "Can''t we 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 check the situation of other units...especially the aviation power group. Academician Chang himself must be invited."


    Nowadays, if you want to start new projects in the aviation industry, especially new big projects, it is almost impossible to avoid the name Chang Haonan.


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


    But Zhang Hongbiao waved his hand:


    "Director Li has personally contacted Academician Chang, and it is estimated that he will be back from Haojing in two days."


    As he spoke, he lightly knocked on the table for emphasis:


    "If you consider his schedule, you''d better arrange it until the beginning of August so that Academician Chang can return to the capital and get everything done. Now is the critical stage of the turbofan 20 test, and Hao Jing''s work is also very busy. nervous."


    In fact, compared to Turbofan 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.


    Just assume that most of the work on Haojing''s side is high bypass ratio turbofan engines.


    "If this is the case, we will try to schedule the meeting in the first week of August..."


    Song Jiaxiang answered while making a mark on the calendar at the front of his notebook.


    Zhang Hongbiao continued to add:


    "In addition, the leaders of your group should communicate with the subordinate main engine research institutes in advance to summarize the power plant requirements of the fourth-generation fighter jets in advance. Just follow the analysis just now as a template, and it can also be used as a reference for Academician Chang and the others. , as much as possible like the J-10, the power and aircraft can be developed and matured at the same time.”


    In fact, when he said this sentence, he was already preparing for the end.


    But Song Jiaxiang then 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. It is rare for a layman to guide an expert.


    But when it comes to some details, it''s still almost meaningless.


    So after thinking about it again and again, I finally said:


    "In fact, Director Zhang, when Academician Chang designed the Turbofan 10 many years ago, he considered the power requirements of the new generation fighter jets. At that time, it was based on the fourth generation engine, so we estimate that Academician Chang''s He should have had his own plan.”


    "In addition, the power requirements of the fourth-generation aircraft plan are not as stringent as imagined... For example, the supersonic cruise capability mentioned before is not entirely related to power. Among the several previously submitted plans, there are actually many Some are biased towards low-drag optimization, and can even use the current turbofan 10B to achieve supercruise..."


    "In short, the design 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 to adapt and adjust..."


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


    Yu Gong, the Aviation Industry Corporation of China has not been using resources for nothing in recent 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". Instead, it should be a combination of aerodynamics and power, external flow and internal flow. conduct.


    Privately speaking, maybe Chang Haonan does have the ability to take care of the entire project, but as a new group leader who has just taken office, he does not want to leave an impression on his superiors that "things can''t be done without outsiders."


    …


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


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


    To be able to produce results like this, to be honest, even exceeded his initial expectations. But what surprised him even more was that his superiors would react so violently and clearly.


    You know, the selection and establishment of the fourth-generation fighter jet in the previous generation was probably before 2008, but this wave was almost two years ahead of schedule.


    It seems that after the timeline was changed, there was no longer a series of events that happened in the middle, and the balance of power between the two sides was not as disparate as it was in the previous life, which led to certain changes in the struggle strategies of the decision-makers.


    To put it simply...


    If there is no other way, who the **** wants to be a turtle?


    Fortunately, Chang Haonan was already prepared for this.


    Or rather, he has been preparing for this day since the first day he came back from rebirth.


    Therefore, there is no panic about being two years ahead of schedule.


    After receiving the call, Chang Haonan briefly arranged the work in Haojing, and then flew back to the capital as quickly as possible...


    "Academician Chang, I''m sorry for calling you back from Haojing 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 already made a lot of preparations in the overall design. It is just because of the lack of specific requirements and evaluation that they have not been able to reach a consensus. Now the Air Force has It is expected that a program seminar will be held early next month to determine the research and development feasibility and technical route.”


    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 an attendance certificate.


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


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


    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...


    "As for 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 a table I have listed of 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 need the Industrial and Construction Committee to pool national resources so that they can be solved as soon as possible. get along with!"
