Chapter 623 Turbofan 10, a full-authority digital control system
"I don't know what Captain Ruan thinks is the reason for this unusual and mysterious phenomenon?"
The reporter was obviously not prepared to let go of Ruan Yingjun easily, but for the latter, as long as the other party could shift his focus from the incident just now, it would be easy to say anything else.
Therefore, he can only give his own answer:
"The specific reason, I think it should be left to scientists to study, but if you judge from the perspective of an old seafarer, it is very likely that there is a strong and chaotic magnetic field around, so the magnetic compass will be interfered with, and at the same time, the strong magnetic field will also have an impact on the electromagnetic wave signal, and the wrong data given by GPS navigation should also appear in this way......"
As he spoke, Ruan Yingjun himself didn't believe what he said.
However, judging from the immersion of several people on the other side, they may really believe it......
Of course, believing it is a good thing and can save you a lot of trouble.
After some nonsense, Ruan Yingjun, who was a little dry-mouthed, added:
"In addition, everyone, the stakes are high, and regarding the mysterious events that happened during the period just now, I hope that you will pay attention to the selection of content when reporting, and focus on the content that has been booked before the voyage."
A small fish and shrimp like him makes such a straightforward request for the content of the report, and if it is left at other times, it will only have the opposite effect.
Well, the more you don't want them to report, the more they want to report.
But Ruan Yingjun had already done enough foreshadowing just now, and now that he was bluffing, he really scared the other party.
The reporter's lips trembled slightly, and he looked at the GPS positioning system next to him, which still displayed obvious abnormal data, and the magnetic compass that rotated irregularly from time to time, as if he thought of the mysterious horror legend about the Bermuda Triangle, and nodded with a pale face.
On the other hand, it is obviously impossible for Huaxia to know that this ordinary equipment test has been defined as a occult event by the opposite side under many coincidences and human factors.
And in the future, it will become the fuse of a series of other events, and even derive many literary works.
At this point, they simply judged—
The other party coaxed.
Actually, this judgment is not wrong.
After all, Ruan Yingjun wanted to go back from the beginning.
Later, it was just a foreshadowing of the rationalization of this behavior.
As a result, the two planes, which were already about to reach the limit of fuel, naturally returned quickly, while the Huangshi hung far behind the Fan Wulao for several hours.
It wasn't until late that day, after making sure that the other party had no intention of returning again, that he turned around and left.
And when this story went about twists and turns, and finally reached Chang Haonan's ears, it was almost two months later.
In the summer and autumn, 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 Il-76 transport aircraft for complete bench performance tests.
Thanks to the larger pressurized cargo tank, the testers of the 606 Institute and the Dawn Group also flew to the 624 Institute together with the test prototype.
As for Chang Haonan...... During this time, the J-10 improvement project was originally handled in Rongcheng, and it was only 100 kilometers away from Fucheng.
Just take a fly and it's over.
The time spent at the airport is longer than the time in the sky.
It was also on the way from Fucheng Airport to 624 that he heard the episodes in the test process from Xu Yang, who had been here for almost two months.
It's just that although the latter is said for fun, Chang Haonan doesn't sound like it's exactly fun.
The last time China and France conducted a joint anti-submarine exercise, it was also a complete coincidence that an underwater villain squatting on the edge of the sea area was caught preparing to reconnoiter intelligence.
Although these two times seem to be lucky, according to the law of a thousand cockroaches......
When you find a cockroach in the house, then there are probably a thousand cockroaches on 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 the 624 Institute, two old acquaintances, Dean Li Rongzai and Chief Designer Jiang Fuhe, were already waiting at the door of the design building.
After some greetings, the latter faced Chang Haonan, who had just gotten out of the car and was carrying a bulging briefcase, looked up and down for a long time, 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 complex.
If I have to say it, it is probably a little unwilling feeling mixed with envy.
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 whole process.
The key is that the 624 Institute, as a turbine institute, is responsible for the pre-research of aero-engine-related technologies.
As a result, others can do projects faster than their own pre-research.
At this meeting last year, Jiang Fuhe had just changed the thrust-to-weight ratio 9 stage thrust derived from the core engine of the R-79V-300 turbofan engine from the conventional model to the vertical take-off and landing model, so as to avoid the edge of the turbofan 10.
As a result, it's only been a year of work, how did you start bench testing?
Even if the turbofan 10 is actually a "new" project that has been approved three times, this is outrageous, right?
Moreover, the thing he fears the most is-
After Chang Haonan finished researching the turbofan 10, will he turn around and engage in vertical take-off and landing engines?
Jiang Fuhe has now understood that once the person in front of him enters a certain field, then the others basically have no chance.
But you can't stay away from Chang Haonan's project for the rest of your life, right?
On the one hand, as the chief designer of the 624 Institute, although he admits that his skills are not as good as others, he always has a bit of dignity.
On the other hand, as the ancients said.
Cut five cities today, cut ten cities tomorrow, and then sleep peacefully. Looking at the four realms, and the Qin soldiers are at the top.
You can't just dodge......
He was thinking about these things in a mess, and for a moment he was a little cold.
Fortunately, Li Rongzai, who was next to him, was not obsessed with this, and immediately added in a half-joking tone:
"Moreover, by the way, it also helped us build a complete set of aero engine testing standard system."
"I'm an old man who only became the dean this year, but I'm ...... naked."
A high-EQ speech supplemented the slightly embarrassing atmosphere just now.
"Everywhere, they are all comrades in the aviation industry system, there is no need to divide them so ......"
Chang Haonan also felt that Jiang Fuhe's mood seemed to fluctuate a little, but he didn't care about it at this time.
After all, the Class II prototype of Project 10 is still waiting for the engine.
The enlarged body, the AL31FN is not very able to push.
"Mr. Chang, during this time, with the assistance of the Institute of Computing of the Academy of Sciences, we have completed the upgrade of the No. 101 high-altitude platform ahead of schedule according to your requirements."
Although Jiang Fuhe feels very bad now, he is not too late to delay his business because of his personal feelings:
"In addition, the prototype B0101 was sent to us the day before yesterday, and as soon as you confirm that it is correct, you can start testing."
In fact, this is also the reason why Xu Yang will appear on Fucheng's side.
She was not directly involved in the Taihang project.
However, because the turbofan 10 is designed with the use of full authority digital control system (FADEC) in mind, compared with the old model, the test content and test method are very different, coupled with the 14 tons of theoretical thrust for Huaxia, so that the SB101 aerial platform needs to be improved to control logic and bench structure to complete the test.
As for why the first prototype was called B0101......
Because the benchmark model of the turbofan 10 is actually a single model prepared for the J-10, that is, the performance shown by Chang Haonan in the PPT of the 611 before, but the vortex is expected to be installed on the J-11, which is the derived thrust reduction model-
After the calculations of the 601 Institute and the technical staff of Sukhoi, it was found that with the current state of the J-11's fuselage design, after the sea-level thrust is raised to 2*13.2 tons, the marginal benefit brought by further improvement will be very small.
It translates into higher reliability and service life.
Especially for the Huaxia Air Force, which has not yet played much with the third-generation fighter and the third-generation turbofan engine, but may soon start to contact the third-generation and a half-generation aircraft and engines.
It's always good to save more snacks.
It is only due to the change in the nomenclature rules of the Air Force equipment in the middle that the base type is called turbofan 10B, and the thrust reduction type is 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 station and see how ready the test work is!"
