Chapter 883 New equipment of the navy and air force


    In fact, after opening up the idea, the progress of the project was far more optimistic than everyone expected, including Chang Haonan.


    This is determined by the principle of optical signal propagation.


    The speed of light is constant, one of the most basic laws of the universe.


    In daily life, electrical signals and optical signals can basically be considered as “instantaneous” transmission.


    ??Moreover, if in a complete vacuum condition, the electrical signal exists in the form of electromagnetic waves, then it can indeed be equal to the speed of light.


    But if you look into it more deeply, it’s not the same thing—


    ?In practical engineering applications, electrical signals often rely on current to be conducted in the medium.


    ??When the medium is a single copper or silver wire, electrical signals can travel at about two-thirds to three-quarters of the speed of light.


    Still not much different.


    ?However, the conductive medium in a complex system obviously cannot have only one wire.


    ?Various electronic components can have a negative impact on current conduction.


    ?The end result may even be one to two orders of magnitude slower than optical signals.


    Therefore, the project team only replaced the cables in the prototype with optical fibers and replaced the supporting equipment accordingly, which greatly reduced signal delay and distortion.


    For picosecond lasers, it is already a barely usable level.


    At least other groups can proceed with the project normally according to the original plan and put the results on the prototype for actual machine testing.


    Rather than everyone stopping and waiting for Huo Penghua''s progress.


    This also made all the technical personnel involved in R&D breathe a sigh of relief.


    Especially Chang Haonan.


    ?Last year, he was able to stay in seclusion for a month or two and only exchange minimal information with the outside world. That was because there were no major project nodes and no situation changes that required special attention.


    But it’s already 2001.


    Times have changed.


    The current month of March can be considered calm, but the next three quarters, if nothing unexpected happens, can be said to be full of big news.


    ?There are roughly four or five types of models related to Chang Haonan that are planned to be mass-produced this year or delivered to the troops in small batches for trial use.


    Not to mention the outrageous and ruthless work that will be done in the second half of the year——


    Although the current timeline has deviated slightly from the previous life, whether intentional or not, Chang Haonan has avoided exerting too obvious influence on the Middle East in recent years.


    Just to wait for this wave.


    So, as the main leader of the aviation power group, and someone who can also influence the direction of policy to a certain extent, he must be able to multi-task.


    ?Ultra-short pulse laser processing is the biggest project at hand, so it is always good to save some energy from it.


    As if to confirm this idea.


    In late March, Chang Haonan, who was busy working on the project, received two invitations.


    The first one comes from Qinfei Group.


    The Air Police 200 early warning aircraft has completed most of the national identification projects.


    Considering that the remaining part is to examine the adaptability under extreme weather conditions and needs to wait for a time window to appear before proceeding, and the assessment content is only related to airborne equipment and does not involve flight safety, the superiors decided to convert the verification aircraft into a prototype. The Air Police 200, which was converted into a mass-produced prototype, was delivered to the aviation force in advance for trial use.


    Chang Haonan, as the deputy chief engineer of the project, had almost no formal appearance during the research and development process, but at least participated in the pre-research and overall plan determination before the project was established, and was naturally invited to attend the delivery ceremony.


    Originally, this should be a good thing.


    Chang Haonan didn''t mind spending two or three days on a trip to Nanzheng.


    However, just when he had arranged his schedule and was preparing to reply to the Qin Fei Group, he received another invitation from Shengjing.


    The content...is almost the same as the previous one.


    ??The J-11B, which has been in trial production since the second half of last year, has finally saved up enough 12 turbofan 10A engines for 6 aircraft, which can be delivered to the troops...


    “That’s great…”


    Chang Haonan looked at the two envelopes in front of him, and suddenly had a strange feeling that "the child has grown up."


    After all, these two projects are typical examples of “he was involved in them, but he did not directly participate in them, and they were successfully completed in the end.”


    This is also what Chang Haonan hopes to see most.


    The only problem is—


    Although they are not arranged at the same time, they are just the front and rear feet...


    ?This cannot entirely be blamed on the arrangements of the aviation industry. In the final analysis, Party A has the final say on the delivery of mass-produced machines.


    ??Although the People''s Liberation Army does not engage in feudal superstition, it is obviously a routine operation to choose a memorable day for important events.


    Of these two models, one was delivered to the Navy by Qinfei Group, and the other was delivered to the Air Force by Shengfei Group...


    Logically speaking, there should be no influence at all on each other.


    So, both sides chose the day of March 25th.


    That was the day when the large-scale southeast exercise ended five years ago.


    The meaning behind it is self-explanatory.


    It was just a pain for Chang Haonan who was invited at the same time.


    For the first time, the Navy has its own early warning aircraft.


    For the first time, the Air Force has a fully domestically produced third-generation fighter jet.


    Two happy things coincide with each other...


    Why does it become...


    Ahem…


    Fortunately, the delivery ceremony of the Air Police 200 was in the morning, while the J-11B was in the afternoon.


    It was barely a time difference.


    …


    ?Chang Haonan flew from Beijing to Nanzheng the day before, that is, on the afternoon of March 24.


    ??Accompanying him was Zhang Hongbiao, one of the deputy directors of the Science and Technology Commission.


    The two of them are old acquaintances.


    We have participated in the celebration ceremony of the C808 passenger aircraft completing its certification test flight before.


    “Are you going back to the capital tomorrow afternoon?”


    When the plane was about to land, Zhang Hongbiao asked Chang Haonan.


    ifier


    The latter shook his head expressionlessly:


    "After participating in this one, go to Shengjing immediately to participate in the next one..."


    ?This answer made Zhang Hongbiao stunned for a moment, and then he couldn''t help laughing:


    “Yes, I forgot, the delivery of the J-11B is also tomorrow.”


    Chang Haonan’s head was covered with black lines, he held his forehead and sighed:


    “So you don’t have to go there?”


    "Need not."


    ?Zhang Hongbiao could still keep his expression calm, but his tone inevitably revealed a bit of schadenfreude:


    “There is only one you in China, but our Science and Technology Working Committee does not only have one deputy director, so there is no need to bother me... Shengjing is Lao Huai’s past.”


    At this point, his tone suddenly changed again:


    “This trip was originally requested by Lao Huai, saying that he wanted to take a last look at the projects he had handled before retiring…”


    Lao Huai naturally refers to Huai Guo Mo.


    Deputy director in charge of external technical exchanges.


    ??He was also one of the leaders of the Science and Technology Commission that Chang Haonan first came into contact with.


    He was deeply involved in the original negotiations with Sukhoi on Project 11.


    Including details related to the introduction of production lines and cooperation in improving the airframe structure.


    ??Now the J-11B has been successfully delivered. Although it is only a trial production batch, it can be regarded as a successful conclusion to the entire project.


    When Project No. 11 was signed, I am afraid that even Huai Guomo himself could not imagine that he would be able to see this day before he retired.


    After all, to produce a heavy-duty third-generation aircraft from scratch, improvements must be made on this basis.


    ?At the time, it seemed that it had to be a long-term project with a cycle of 10-15 years.


    By the time Huai Guomo retired, the team that Chang Haonan had just returned from his rebirth, with the exception of Ding Gaoheng, had all retreated to the second line, or simply retired.


    As for Ding Gaoheng…


    Judging from the current situation, after two years, there should be a chance of making another half step forward.


    ?Of course, whether it can be successful depends not only on Director Ding’s own efforts, but also on Comrade Xiao Chang’s progress in promoting the timeline...
