Chapter 513 The intersection of two eras
Later that day, Chang Haonan flew to Fucheng with the IL-76 transport plane transporting the engine.
Chang Haonan is not here for the first time.
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, 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 have directly changed the development path of the entire Chinese aviation industry...
It should be said that in the past two years so far, he has achieved The results far exceeded what was expected when he was first reborn.
Of course, he has already done almost all the projects that are easier to achieve quick results in a short period of time.
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 off 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 attire, 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 had 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 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 the project seminar..."
In the original timeline, in SB101 After the test bed was completed, 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 Chang Haonan is publishing papers, and the corresponding author is himself...
In short, Academician Liu is obviously preparing to continue to shine in the education world, while the new Dean Li is affected by the butterfly effect One of the countless people who arrived.
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".
As for the man 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 marked the aviation engine test standard. It's different, but after all, it only completed the part related to the compressor intake distortion. In terms of workload, it is not even 10% of the engine testing process.
The improvement and revision of other parts were led by Liu Zhenxiang and completed recently 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 have to celebrate the New Year in Fucheng again..."
Chang Haonan took out a ballpoint pen and signed himself at the end of the test project book name, he 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 used to spend the New Year in Fucheng?"
Chang Haonan did indeed live in Fucheng in his previous life. I often celebrate the New Year in Fucheng, but they are always at Jiuyuan.
Of course, this kind of thing must not be said.
“Not in Fucheng, but I spend a lot of time 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 moved through the track to the high-altitude platform test workshop Shipped internally.
Chang Haonan followed quickly.
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 identify the specific model.
In 1998, there were only a few types of Chinese aero-engines, and most of them were directly or indirectly involved by him.
It is surprising that a truth that he has no impression of suddenly appears.
“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 senior model that was established in 1966. It was normal that he did not 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 isn’t it that the Q-5 is still in use...”
Jiang Fuhe, who was half a body behind, explained:
“Originally, Hongdu started to strengthen 5D at the end of 1996, and now it has basically been finalized.”
“But because of the pickaxe The progress of the improved JH-7A in Beijing has far exceeded expectations, and it will soon be 100% domestically produced. Therefore, this model, along with the turbojet 6D engine that has been extended its life, has lost its positioning and has been transferred to the technical reserve. ..."
"Strong 5D..."
To be honest, Chang Haonan has 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, nowadays On the timeline, it should have no chance of entering mass production again.
It's just pity for 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 it has been ruthlessly eliminated by the torrent of the times. One...
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, even Chang Haonan cannot play any tricks 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 the Chinese aviation industry.
