The military-industrial scientific research system of the academic master.

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 total pressure distortion at the aeroengine inlet.

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

However, through 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 Chinese aviation industry...

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

Of course, the projects that are relatively easy to achieve quick results have been basically done by him.

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

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

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

"Mr. Chang, we meet again."

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

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.

But the last time he came to 624 Institute, 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...

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

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."

"When we were 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..."

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

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.

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

Of course, it's just a name.

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

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.

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

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

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

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

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

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

The latter provided a sample of aero-engine testing standards, but after all, it only completed the part related to compressor intake distortion. In terms of workload, it did not even account for 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 9A-02, 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 will celebrate the New Year in Fucheng again..."

Chang Haonan took out a ballpoint pen, signed his name at the end of the test project book, and said 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?"

It is true that Chang Haonan spent many New Years in Fucheng in his last life, but they were always at the Ninth Courtyard.

Of course, this kind of thing must not be said.

"Not 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 9A-02 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 now?"

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.

In 98, there were only a few types of Chinese aircraft engines, and most of them were directly or indirectly involved by him.

It was surprising to see a sudden truth that he had no memory of.

"Oh, this is an improved model produced by our local Rongfa factory, 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, so it was normal for him not to recognize it for a while.

But this is 1998, and we can still see improved models of the engines from our 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 body behind, explained:

"Originally, Hongdu started to strengthen 96D at the end of 5, 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, Chang Haonan had never thought of this model since his rebirth.

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, there should be no chance that it will enter mass production again.

It's just pity that Hongdu Group has only two main products, K8 and Qiang 5 (Chujiao 6 was discontinued at this time, and 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 face specific situations in a specific period.

In the context of the 21st century, it is impossible for even Chang Haonan to do anything on this old machine...

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

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