Chapter 624 Turbofan 10, full authority digital control system

"I wonder what Captain Ruan thinks is the reason for this unusual and mysterious phenomenon?"

The reporter was obviously not prepared to let Ruan Yingjun off easily, but for the latter, as long as the other party could shift their focus from the incident just now to other places, everything else would be easy to talk about.

Therefore, he could only bite the bullet and give his answer:

"I think the specific reasons should be left to scientists to study, but judging from my perspective as an old seaman, it is very likely that there is a strong and chaotic magnetic field around, so the magnetic compass will be disturbed. At the same time, the strong magnetic field It will also have an impact on electromagnetic wave signals, and this is how the erroneous data given by GPS navigation should appear..."

As he spoke, Ruan Yingjun himself didn't believe what he said.

But judging from the immersed performance of several people on the other side, they may really believe it...

Of course, it is a good thing to believe it, as it can save you a lot of trouble.

After the nonsense, Ruan Yingjun, who was a little thirsty, added:

"In addition, everyone, this is a serious matter. Regarding the mysterious incident that happened just now, I hope you will pay attention to the content selection when reporting, and focus on the content that was booked before the voyage."

For a small fry like him to make such straightforward demands on the content of reports, if left at other times, it will only have the opposite effect.

As for the media, the less you want them to report it, the more they want to report it.

But after all, Ruan Yingjun had laid the groundwork just now, and now that he was bluffing, he really bluffed the opponent.

The reporter's lips trembled slightly. He looked at the GPS positioning system next to him, which still displayed obviously abnormal data, and the magnetic compass that rotated irregularly from time to time. He seemed to be thinking of the mysterious and terrifying legend about the Bermuda Triangle, and nodded with a pale face. .

On the other side, it is obviously impossible for China to know that this ordinary equipment test has been defined as a occult event by the opposite side due to many coincidences and human factors.

And it will become the trigger for a series of other events in the future, and even spawn many literary works.

At this time, they simply judged——

The other party was scared.

In fact, this judgment is correct.

After all, Ruan Yingjun wanted to go back from the beginning.

Later, it was just a rationalization for this behavior.

As a result, the two planes, which were almost reaching their fuel limit, naturally returned quickly, while the Huangshi hung far behind the Pham Ngu Lao for several hours.

It wasn't until nightfall that day and it was confirmed that the other party had no intention of returning again that he turned around and left.

And when this story went through many twists and turns and finally reached Chang Haonan's ears, it was already almost two months later.

As summer turns to autumn, the first fully produced turbofan 10 prototype B0101 has also completed various tests before leaving the factory, and was transported by an IL-76 transport aircraft to 624 for complete bench performance testing.

Thanks to the larger pressurized cargo compartment, testers from the 606th Institute and the Dawn Group also flew to the 624th Institute together with the test prototype.

As for Chang Haonan... During this period, he was working on the J-10 improvement project in Rongcheng, which is only 100 kilometers away from Fucheng.

Just hit it and fly over.

The time spent at the airport is longer than the time spent in the sky.

It was also on the way from Fucheng Airport to the 624 Institute that he heard these little episodes in the testing process from Xu Yang, who had been here for almost two months.

However, although the latter was said as a joke, to Chang Haonan's ears, it was not entirely a joke.

The last time China and France held a joint anti-submarine exercise, they also caught an underwater villain squatting on the edge of the sea preparing to conduct reconnaissance intelligence by complete coincidence.

Although these two times seemed to be good luck, according to the Thousand Cockroaches' Law...

When you find one cockroach in your house, there may already be a thousand cockroaches in the dark side of the house.

In other words, there will only be more similar cases that go undetected.

"There is still a long way to go to protect maritime rights and interests..."

……

When the pick-up convoy arrived at Institute 624, two old acquaintances—dean Li Rongzai and chief designer Jiang Fuhe—were already waiting at the entrance of the design building.

After some pleasantries, the latter faced Chang Haonan, who had just gotten off the car and was carrying a bulging briefcase. He looked up and down for a while, and then sighed softly:

"Before today, I never dreamed that someone would come to us for testing on three different projects in two years..."

His expression and tone were very complicated.

If I have to say it, it's probably just envy mixed with a little bit of unwillingness.

After all, from the turbojet 14, to the turbofan 9, and now to the turbofan 10.

Chang Haonan's movements were so efficient that Jiang Fuhe watched almost the entire process.

The key is that 624 Institute, as a turbine institute, is already responsible for pre-research on aero-engine related technologies.

As a result, others can complete the project faster than I can do pre-research.

At this meeting last year, Jiang Fuhe had just converted the 79-level thrust-weight ratio derived from the R-300V-9 turbofan engine core from a conventional model to a vertical take-off and landing model to avoid the 10-level thrust of the turbofan engine. Edge.

After all, it’s only been a year, so why have we started bench testing?

Even if Turbofan 10 is actually a "new" project that has been approved three times, is this too outrageous?

Moreover, the thing he fears most is——

After Chang Haonan has studied the turbofan 10, will he start working on a vertical take-off and landing engine again?

Jiang Fuhe has now understood that once the person in front of him enters a certain field, others will basically have no chance.

But you can’t avoid Chang Haonan’s project for the rest of your life, right?

On the one hand, as the chief designer of Institute 624, although he admits that his skills are inferior to others, he still has a bit of dignity.

On the other hand, as the ancients said.

Cut five cities today, cut ten cities tomorrow, and then have to sleep well overnight. He started to look around the surrounding areas, and the Qin soldiers arrived again.

You can't escape just by hiding...

He was thinking about these things in confusion, and he felt a little cold for a moment.

Fortunately, Li Rongzai next to him didn't have any obsession with this, and immediately added in a half-joking tone:

"Moreover, it also helped us build a complete aero-engine testing standard system."

"I, an old man who only became the dean this year, have been blessed..."

A speech with high emotional intelligence restored the slightly awkward atmosphere just now.

"Everywhere, we are all comrades in the aviation industry system, there is no need to be so detailed..."

Chang Haonan also felt that Jiang Fuhe's mood seemed to be fluctuating a bit, but he didn't care about worrying about it at this time.

After all, the Type II prototype of Project 10 is still waiting for the engine——

The enlarged body is unlikely to be pushed by the AL31FN.

"Mr. Chang, during this period, with the assistance of the Computing Institute of the Academy of Sciences, we have completed the upgrade of No. 101 High Altitude Observatory ahead of schedule in accordance with your requirements."

Although Jiang Fuhe feels very bad now, he will not delay business because of personal feelings:

"In addition, prototype B0101 has been sent to us the day before yesterday. As long as you confirm it is correct, you can start testing."

In fact, this is also the reason why Xu Yang appears in Fucheng.

She was not directly involved in the Taihang project.

However, because the Turbofan 10 was designed with the full authority digital control system (FADEC) in mind, the test content and test methods are very different from the old model. In addition, it is earth-shattering for China. The theoretical thrust of the Ghost is 14 tons, so that the control logic and bench structure of the SB101 high-altitude platform need to be improved to complete the test.

As for why the first prototype was called B0101...

Because the baseline model of the Turbofan 10 is actually a single-engine model prepared for the J-10, which is the performance shown by Chang Haonan during the PPT lecture on 611. On the contrary, the turbofan is expected to be installed on the J-11, which is the derived reduction model. Push model——

After calculations by technicians from the 601 Institute and Sukhoi Company, it was found that with the current J-11 airframe design, after the sea level thrust is raised to 2*13.2 tons, the marginal benefit from further improvement will be very small.

Rather it translates into greater reliability and service life.

Especially for the Chinese Air Force, which has not yet fully understood the third-generation fighter jets and third-generation turbofan engines, but may soon begin to come into contact with third-and-a-half-generation aircraft and engines.

It's always good to save a little more.

It was only because the Air Force equipment naming rules changed midway that the baseline type was called Turbofan 10B, and the reduced-thrust type was called Turbofan 10A.

Chang Haonan raised his wrist and looked at the time.

It's still early for dinner.

"Let's go to the high-altitude platform to see the preparations for the test!"
