The Military-industrial Scientific Research System of the Academic Master Chapter 513

Chapter 513 The intersection of two eras

Later that day, Chang Haonan flew to Fucheng with the IL-76 transport plane transporting the engine.

This is not the first time Chang Haonan has come here.

 He ​​was sitting in the passenger seat of the truck transporting the engine, looking at the 624 gates in front of him, and couldn't help but recall the situation when he first came here more than a year ago.

 When he was testing the turbojet 14 before, it was here that he perfected the national military standard operating procedures for the assessment of the total pressure distortion of the aeroengine inlet.

 At the beginning, his idea was just to make the testing process of the specific model of turbojet 14 legal.

However, due to many subsequent coincidences, that operating manual-like document eventually became the basis and model for a new national standard.

  The ensuing series of butterfly effects directly changed the development path of the entire aviation industry in China...

It should be said that in the nearly two years until now, he has achieved results that far exceeded what he expected when he was just reborn.

Of course, he has already done almost all the projects that are easier to achieve results in a short period of time.

But the last time he came to Institute 624, the theoretical director and secretary here was still Liu Zhenxiang. Among the leaders he came into contact with at that time, he should not be the one in front of him...

 The sound and inertia of the truck braking brought Chang Haonan out of his thoughts.

 “Mr. Chang, we meet again.”

 The leader was wearing a dark blue woolen tunic suit and a leather hat.

 Fortunately, the other party quickly introduced himself:

“Li Rongzai, who was transferred from Shengjing at the end of last year, took over the position of Academician Liu Zhenxiang.”

 He got out of the car from the passenger seat, and several leaders of Institute 624 who had been waiting here came to greet him.

 Jiang Fuhe, the chief designer of the 624 Institute, had some interactions with each other at the turbofan 10 design review meeting.

 In the original timeline, after the completion of the SB101 test bench, Liu Zhenxiang still served as the dean of Institute 624 for a long time.

 And through hard work, I got the title of Chang Haonan's "joint training mentor" from Du Yishan.

However, in this life, perhaps due to the influence of Chang Haonan, he has transferred his organizational relationship back to Beijing Hang University as a professor.

After saying hello and briefly chatting, Li Rongzai personally directed the staff to prepare to unload the truck.

 The rest are hard-core products like the turbofan 10.

“When I was working on the turbojet 14, I was responsible for the research and development of the fuel and oil delivery part. I met you several times during project seminars...”

Now when Chang Haonan publishes papers, the corresponding author writes himself...

 As for the person following Li Rong, Chang Haonan was much more familiar with it.

In short, Academician Liu is obviously preparing to continue to shine in the education world, and the new Dean Li is one of the countless people affected by the butterfly effect.

However, this must not be shown, so Chang Haonan shook hands with the other party enthusiastically.

Of course, it's just a name.

 Jiang Fuhe took out a bound paper material from nowhere and handed it to Chang Haonan.

Chang Haonan was a little unfamiliar with this kind of dress, but when he heard the other party's greeting, it was obvious that he had met him before.

Although Chang Haonan himself is only in his early twenties, at this moment, he suddenly has a mysterious feeling that "the world is full of peaches and plums".

“Mr. Chang, this is the test content we have initially determined, modified according to the latest version of the national military standard, please take a look.”

  The latter set a pattern for aero-engine testing standards, but after all, it only completed the part related to compressor intake distortion, and the workload was less than 10% of the engine testing process.

 The improvement and revision of other parts were led by Liu Zhenxiang and completed in 624.

 So even Chang Haonan himself is not very clear about the testing process after the version update.

 For a major modification like the 902, although the content that needs to be tested is less than that of a new engine like the previous turbojet 14, it cannot be completed in a few days. Chang Haonan spent almost half an hour looking at the list of necessary test items.

“Now, I guess I'll be celebrating the New Year in Fucheng again…”

Chang Haonan took out a ballpoint pen and signed his name at the end of the test project book, saying with some helplessness.

 Jiang Fuhe took the information in his hand and put it away. Hearing this emotion, he raised his head curiously:

“Mr. Chang spent the New Year in Fucheng before?”

Chang Haonan did spend a lot of time celebrating the New Year in Fucheng in his last life, but it was always at the Ninth Courtyard.

 Of course, this kind of thing cannot be said.

“There are not many in Fucheng, but there are quite a few people celebrating the New Year outside because of work.”

 Fortunately, the other party just asked casually and did not continue to dwell on this topic.

While the two were chatting and processing necessary documents, the 902 prototype was also unloaded from the flatbed trailer and slowly transported to the interior of the high-altitude platform test workshop via the track.

Chang Haonan quickly followed.

After walking a few steps, his sharp eyes spotted a much smaller engine being transported out of another track next to it.

“Are there any other test tasks here?”

Chang Haonan stared at the small engine, which was about a quarter of the size of the turbojet 9A, for a while, but did not recognize the specific model.

 At this time in 1998, there were only a few types of Chinese aircraft engines, and most of them were directly or indirectly involved by him.

　　It was a bit surprising to see a truth that suddenly appeared that he had no impression of.

“Oh, this is an improved model produced by our local Rongfa factory, the turbojet 6D.”

“Isn't this the engine of the J-6? Is it still being modified?”

Chang Haonan was shocked.

The Turbojet 6 is a super old-timer that was established in 1966. It was normal for him not to recognize it for a while.

But it's 1998, and you can still see improved models of the engines from your grandfather's generation?

“Of course the J-6 has been discontinued a long time ago, but aren't there still J-5s in use...”

Jiang Fuhe, who was half a step behind, explained:

“Originally, Hongdu began to strengthen 5D at the end of 1996, and now it has basically been finalized.”

"But because the progress of the improved JH-7A in Haojing is far ahead of expectations, and it will soon be 100% domestically produced, this model, along with the turbojet 6D engine that has been extended its life, has lost its positioning. Entering the technical reserve..."

 “Strong 5D…”

To be honest, since his rebirth, Chang Haonan has never thought of this model.

 After Jiang Fuhe said this, he remembered that the Qiang 5D, as the last mass-produced model of the Qiang 5, was originally put into production in 1998 and discontinued in 2012...

Of course, on today's timeline, it should have no chance of entering mass production.

It's just pity Hongdu Group. It originally only had two main products, K8 and Qiang 5 (Chujiao 6 was discontinued at this time, but was resumed in 2015 in reality). Now one of them has been ruthlessly eliminated by the torrent of the times...

Having said that, this model, which is improved on the basis of the J-6, is basically a specific solution to specific situations in a specific period.

In the context of the 21st century, even Chang Haonan cannot do anything on this old machine...

In the sunset in Fucheng, two engines go in and out, passing each other on the adjacent transportation track.

 Just like the two eras of China's aviation industry.
