Li Hai's conclusion was even more exciting than the previous one. Zhu Wei was even surprised. Why didn't you say it before?
As if hearing Zhu Wei's thoughts, Li Hai explained, "Team leader, I was only able to confirm this after this flight. Before that, I also thought that the problem had been completely solved."
Immediately, he looked at Tang Feilin, who had a solemn expression.
The chief engineer of the first-generation flight control system of Flying Shark was his master. After his master retired, he took over and continued to work on the second generation. The second-generation flight control system currently used in the newly modified Flying Shark is the second generation flight control system.
Lehi's judgment is more appropriately described as an accusation than a conclusion.
Tang Feilin listened patiently and listened attentively. As they said first, discuss the matter as it is, not the person, so let's argue. The more you argue, the clearer the truth will be.
The pilots who could join the experimental training group could be considered as half technicians. Tang Feilin did not underestimate Li Hai's idea.
Li Hai said, "The Flying Shark is based on the T-10K-3, which is the prototype of the Su-33. Mr. Tang, you should be very clear that the T-10K-3 is not in its complete form. The Russians turned it into the Su-33
, has undergone major improvements, the most critical one of which is the flight control system.”
Tang Feilin had heard about these things the year he started working in the factory.
Li Hai said, "Even so, there are still hidden dangers in the Su-33's flight control system, but the probability of problems is much smaller. Why is it so small? There may even be no problems later."
"The reason is very simple, because they fly less. When the Kurdish warships were docked for overhaul and encountered fires and other disasters, the Russians' twenty or thirty Su-33s became just decorations, and subsequent improvements were in vain.
If you don’t have any customers anymore, why do you want to change it?”
Zhu Wei seemed to understand that Li Hai looked at these data from the perspective of a pilot, which was completely different from that of a technician.
The less you fly, the less likely it is to malfunction!
"The Russians have not completely solved the congenital defects in the Su-33 flight control system. Mr. Tang, it is a congenital defect. The Soviets' ideas for designing fighter aircraft are different from ours. For example, they do not bother to improve the maneuverability of the fighter aircraft.
Make weight reduction design, because the high-thrust aero-engine can make up for it. If the existing engine has insufficient thrust, then build one with greater thrust. They have this technical reserve, and it is typical to use the performance of part A to make up for the performance of other parts.
The technique is very simple and very effective.”
"But on the Su-33 fighter, or rather the entire Su-27 family, problems with the flight control system have always existed. It was not until the Su-35 that they completely solved this congenital flaw. The Su-33 and other members of the same family
The fighter plane is different. It has a wing folding mechanism and canards. Not only is it heavier, the wing area is larger, and the counterweight has also changed. You must also know that the flight control used on the Su-33
How complex the system is.”
"The Russians have never thought about re-developing a suitable flight control system. They just patched it up on the original basis. Of course, the Su-35 is an exception. This fighter is also regarded as a complete Su-27.
Because many defects have been solved, the most important of which is the flight control system."
After a pause, Li Hai drank some water and continued, "I have read your technical information, and you have also fallen into the inertia of thinking. You are still following the original path of the Soviets to make improvements, and you have changed them again and again. Although the defects have become
It is no longer visible, but no matter how small the defect is, it still exists. I felt this during today’s flight.”
He recalled, "There was a lot of wind and snow in the sky, and the airflow was very chaotic. There were several times when the fighter plane was on the verge of stalling. If you go back and analyze it by combining the flight parameters with the climate data at that time, you can know the situation at that time."
"I controlled it very carefully. You know, the job of a carrier-based fighter pilot is to thread the needle, and to block the landing is micro control. It was at this time that I felt that the fighter plane was like a giant beast walking on the edge of the cliff, and again
Or a bison whose endurance is approaching the critical point may escape my control at any time. But before that, all the data and parameters prove that it is in a normal state."
Speaking of this, Li Hai said with regret, "I regret it now. I should have been bolder and break through this critical point, and the true status of the fighter plane would naturally come out. Unfortunately, I did not continue to do that...
…”
Zhu Wei immediately cursed, "Aren't you brave enough? Damn, this scared me half to death. This is unprecedented."
Li Hai smiled and said nothing.
At this time, Tang Feilin fell into deep thought.
He also understood that in their eyes, fighter planes were made up of parts and components and had a lot of data, but in the eyes of pilots, they were flesh-and-blood comrades.
It feels like something really wonderful.
Li Hai is right about one thing. Tang Feilin and the others have indeed improved along the previous generation's ideas. The previous generation's ideas are effective, so why not continue to use them? There are so many benefits in saving time, effort and money.
The previous generation relied on ideas provided by Russian technicians hired from outside after the collapse of the Soviet Union...
Thirteen years have passed since the J-15 made its first flight, but the hidden dangers of the flight control system have still not been completely solved. If this fighter is to continue to serve, the manufacturer must face this problem head-on.
For a problem that cannot be solved in thirteen years, maybe it’s time to find a new approach.
Tang Feilin expressed his gratitude to Li Hai without saying anything else. He got up and went to report to the J-15's chief commander.
As soon as he left, Zhu Wei immediately asked Li Hai, "Tell me the truth, is the flight control system of the new Flying Shark still unreliable?"
Li Hai shook his head, "It is more reliable than the previous generation system. As you can see, our flight intensity is so high that there has never been any problem with the flight control system."
"Then why did you attack Mr. Tang? You have completely overturned their research and development results. This is no small matter." Zhu Wei said seriously.
Li Hai said helplessly, "If you are not afraid of 10,000, just be afraid of the worst. Maritime operations often involve dealing with bad weather. If the fighter flight control system cannot withstand the intensity and there is a sudden gust of wind, we will all have to see you at the Martyrs Cemetery."
When Zhu Wei heard this, he nodded slightly, "That's true, the sea cannot be compared with the land."
To put it bluntly, when flying on land, as long as the pilot can eject, the chance of survival is very high, but if a person falls into the vast sea, dozens of warships may not be able to recover him.
"In this case, this matter cannot be trivial. It must be reported to Mr. Li." Zhu Wei said.
Li Hai hesitated, "There's no need to alarm my master, right?"
"This is a big deal. We might have to file a lawsuit. Don't talk about you. I can't handle the pressure even with my body," Zhu Wei said.
Li Hai smiled and said, "I dare you to use my master as a shield."
"He has rough skin and thick flesh, so he can stop it."
