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

It's not the first time Chang Haonan has been here.

Sitting in the passenger seat of the truck carrying the engine, he looked at the gate of the 624 in front of him, and couldn't help but recall the first time he came here more than a year ago.

When he tested the turbojet 14 before, it was here that he perfected the operation process of the national military standard for the evaluation of the total pressure distortion of the air inlet of the aero engine.

At first, his idea was really just to make the test process of the specific model of the turbojet 14 follow.

However, under many later coincidences, the document in the nature of the operation manual eventually became the basis and model of the new national standard.

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

It should be said that in the nearly two years of work so far, he has achieved far more results than he had imagined when he was just reborn.

Of course, the projects that are easier to achieve results in a short period of time have basically been almost done by him.

The rest are all hard bones like the turbofan 10.

The sound and inertia of the truck as it braked brought Chang Haonan out of his thoughts.

He got out of the co-pilot seat, and several leaders of the 624 Institute who had been waiting here came forward one after another.

"Mr. Chang, meet again."

The first one wears a dark blue woolen tunic and a fur hat.

This kind of dress made Chang Haonan a little unfamiliar, but listening to the meaning of the other party's greeting, it was obvious that he had met him before.

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

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

Fortunately, the other party quickly introduced himself:

"Li Rongzai was just transferred from Shengjing at the end of last year to take over the position of academician Liu Zhenxiang."

"When I was working on Turbojet 14 before, I was in charge of the R&D of the lubricating oil delivery part, and I met you a few times when I held a project seminar......

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

However, this life may have been influenced by Chang Haonan, who has transferred his organizational relationship back to Jinghang University as a professor.

And by not knowing how to grind and soak, he obtained the title of Chang Haonan's "joint training mentor" from Du Yishan.

Of course, it's a name.

Now Chang Haonan publishes papers, and the corresponding authors are all writing their own ......

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

Although Chang Haonan himself is only in his early twenties, at this moment, he suddenly has a mysterious feeling of "peach and plum all over the world".

As for the one who followed Li Rong, Chang Haonan was much more familiar.

Jiang Fuhe, the chief designer of the 624 Institute, had some intersections at the turbofan 10 design review meeting before.

After greeting and briefly greeting, Li Rongzai personally commanded the staff to prepare to unload the car.

And Jiang Fuhe didn't know where to take out a bound paper material and handed it to Chang Haonan.

"Mr. Chang, this is the test content that we have preliminarily determined, and it has been modified according to the latest version of the national military standard, you can take a look."

The latter gave a sample of the aero-engine test standard, but after all, it only completed the part about compressor inlet distortion, and the workload was less than 10% of the engine test process.

The improvement and revision of other parts were led by Liu Zhenxiang and completed at the nearest 624.

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

For a facelifted version like the 9A-02, there is less to test than the previous all-new engine like the Turbojet 14, but it is unlikely to be completed in a few days.

Just the list of necessary test items, Chang Haonan looked at it for almost half an hour.

"Now, it's estimated that I'm going to spend 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 helplessly.

Jiang Fuhe took the information in his hand and put it away, and when he heard such an emotion, he raised his head with some curiosity:

"Mr. Chang used to spend the New Year in Fucheng?"

Chang Haonan did spend the New Year in Fucheng in his last life, but he was all on the side of the Ninth Courtyard.

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

"Fucheng doesn't have it, but there are a lot of Chinese New Year days 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 working on the necessary paperwork, the 9A-02 prototype was unloaded from the flatbed trailer and slowly transported through the track to the interior of the high-altitude test shop.

Chang Haonan hurried to follow.

After a few steps, he noticed that a much smaller engine was being transported out of another track next to him.

"Do you have any other testing tasks over here?"

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

In 98, there were only a few models of aero engines in Huaxia, and most of them were directly or indirectly intervened by him.

It was a bit surprising that something suddenly popped up that he didn't have any impression of.

"Oh, this is an improved model made by our local Rong factory, the turbojet 6D."

"Isn't this the engine of the J-6, and it's still being changed?"

Chang Haonan was shocked.

Turbojet 6 is a super old-timer who was finalized in 1966, and it is normal that he can't recognize it for a while.

But it's all 1998, and you can still see an improved model of the grandfather's engine?

"Of course, the J-6 has been discontinued a long time ago, but isn't there still a strong 5 in use......"

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

"Originally, Hongdu began to strengthen 5D at the end of 96, and now it is basically finalized."

"But because the progress of the improved J-7A on the side of Hojing is far beyond expectations, and it will soon be 100% domestically produced, so this model, even with the turbojet 6D engine after the extension of life, has no positioning and has been transferred to the technical reserve......"

"Strong 5D ......"

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

When 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, in today's timeline, it should not have a chance to enter mass production again.

It's just a pity for Hongdu Group, there were only two main products, K8 and Qiang5 (Chujiao 6 was discontinued, and production resumed in 2015 in reality), and now it 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, basically belongs to a specific solution to a specific situation in a specific period.

In the context of the 21st century, even Chang Haonan is unlikely to play any tricks on this kind of classic machine......

In the sunset of Fucheng, two engines enter and exit, staggering on the adjacent transport tracks.

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