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. It's easy to let Ruan Yingjun off, but for the latter, as long as the other party can shift his focus from the incident just now to other places, everything else is easy to talk about.
So, he could only bite the bullet and give his answer:
“I think the specific reasons should be left to scientists to study, but if you look at it from the perspective of an old seaman like me, Judging from the angle, it is very likely that there is a strong and chaotic magnetic field around, so the magnetic compass will be interfered. At the same time, the strong magnetic field will also affect the electromagnetic wave signal. This is how the erroneous data given by the GPS navigation should appear... ”
As he spoke, Ruan Yingjun himself didn't believe what he said.
But judging from the immersed performance of the people on the other side, they may really believe it...
Of course, it is a good thing to believe it, and it can save a lot of trouble.
After the nonsense, Ruan Yingjun, who was a little thirsty, added:
"In addition, everyone, this is a serious matter. Regarding what happened just now, I hope you will pay attention to the content selection when reporting and focus on the content you have booked before sailing.”
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 he was bluffing, and he really bluffed the opponent.
The reporter’s lips trembled slightly, and he looked at the GPS positioning system next to him which still displayed obviously abnormal data, as well as 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. He 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 had almost reached their fuel limit, naturally returned quickly, while the Huangshi hung far behind the Pham Ngu Lao for several hours.
It was not until nightfall that day that the other party made sure that the other party had no intention of returning again, then he turned around and left.
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 passes and autumn comes, the first fully produced turbofan 10 prototype B0101 has also completed various tests before leaving the factory, and was transported to the 624 Institute by an Ilyushin 76 transport aircraft for complete testing. 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 Chengdu, which is only 100 kilometers away from Fucheng.
Just hit it and pass by.
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 624th 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, it was also by complete coincidence that they caught an underwater villain squatting on the edge of the sea area preparing to conduct reconnaissance intelligence.
Although these two times seem to be good luck, according to the law of thousands of cockroaches...
When you find a cockroach in the house, there may be a dark side in the house. Thousands of cockroaches.
In other words, there will only be more similar situations that have not been discovered.
"There is still a long way to go to protect marine rights and interests..."
...
When the pick-up convoy arrived at Institute 624, two old acquaintances—the dean Li Rongzai and the chief designer Jiang Fuhe was already waiting at the door 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 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 as a turbine institute, 624 Institute is already responsible for pre-research work 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 9-level thrust-weight ratio derived from the R-79V-300 turbofan engine core engine from a conventional model to a vertical take-off and landing model. Avoid the edge of Turbofan 10.
It turns out that it has only been a year, so how come bench testing has started?
Even if Turbofan 10 is actually a "new" project that has been approved three times, is this too outrageous?
And what 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...
Thinking about these things in his mind, 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:
“And by the way, he also helped us build a complete aviation system. Engine testing standard system ”
"I, an old man who just 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 classify them in such detail..."
Chang Haonan also felt that Jiang Fuhe's mood seemed to be a little fluctuating, but at this time, Don't bother worrying about this.
After all, the Category II prototype of Project 10 is still waiting for the engine——
The AL31FN is unlikely to be able to push the enlarged body.
"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 I feel bad now, but I don’t want to delay business due to personal feelings:
“In addition, the 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, for China The theoretical thrust of 14 tons is so shocking 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 is called B0101...
Because the baseline model of the Turbofan 10 is actually a single-engine model prepared for the J-10, which is what Chang Haonan said before on 611 The performance shown during the PPT, on the contrary, the vortex is expected to be installed on the J-11, which is the derived thrust reduction model——
After calculations by technicians from the 601 Institute and Sukhoi Company, it was found that with the current 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 understood the use of 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 on snacks.
Only because the Air Force equipment naming rules changed midway, the basic type was called turbofan 10B, and the thrust reduction 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!"
