Chapter 428 - A friend comes from afar
The biggest difference between civilian engines and military engines lies in the design of the afterburner structure.
The former does not say afterburner. The rated output is based on maximum safety and economy as the threshold. Even if you step on the accelerator wildly, it will still be within the rated power.
For operational considerations, the latter sacrificed its service life in exchange for additional power output. After all, the training time and actual combat time are far lower than the civilian hours. If the design life is too long, the cost will be too high, and it will also cause high costs. It will affect the upgrading of active equipment, so the best technology is not necessarily the most advanced.
If military engines are used with reduced power requirements and operating standards, the trouble-free operation time will far exceed the original design parameters.
In a sense, it can also be used as a general-purpose engine.
The PT6A series engine used by the A-39B "Big Mouth Monster" light turboprop attack aircraft that Chen Fei is most familiar with is a fairly mature general-purpose engine with a wide range of applications, large output, and low maintenance The cost is still cheap.
Precisely because the afterburner structure tends to be a radical design, the stability cannot meet the safety standards of civilian engines anyway, so either there is no problem, but when it does it is often a big problem.
Chen Fei blamed the afterburner, which is the main engine part, as the cause of the crash, mostly based on his own experience.
Although he became a monk halfway, with multiple technical certifications and a lot of experience accumulated through supernatural powers, he is now qualified to be called an expert in the industry. In any case, he is no longer the ignorant person he was at the beginning. A layman.

After the No. 2 prototype of the "Masasaurus" project crashed to the ground, the debris was scattered as far as a kilometer away, almost reaching the living area and administrative area of the airport. Multiple drones kept flying in. Fly, repeatedly scan the ground, search for debris and debris, generate a scatter point plan, and simultaneously search for the airborne black box.
Even if the plane crashes, as a valuable experience from which lessons can be learned, naturally not even a single fragment can be let go.
The drone recognized the black box with a little orange-red residue. However, even with special protection design, it is not 100% foolproof.
The black box found was not only torn into pieces, but also all the backup memory chips were burnt.
There was an uproar in the windproof barrier.
This means that part of the data at the last moment of the crash cannot be recovered at all, and the crash data of the No. 2 prototype is incomplete.
"The previous maneuvering data of Unit 2 fully met the design requirements. Why did it malfunction during the leveling stage? It shouldn't have happened!"
"Could it be a magic circle? I saw it The light of elemental energy collapse appeared when the machine lost control. "The data that was finally leveled was a bit abnormal. It may also be that the electronic system failed and the control system had a technical defect."
"How could it be a control system? The control system of 'Masasaurus' was not independently developed. It was a transplanted universal system. Under the same standard, if there were such serious technical flaws, it should have been discovered long ago."
"If it is not a systemic problem or a technical problem, is it a human error? What about the test pilot? The situation of the test pilot How's it going?"
"My thigh was broken when I landed, and I'm undergoing surgery...I'm afraid we won't be able to talk until the day after tomorrow."
"Let's check other problems first before the elemental energy collapses. There is smoke in the aircraft body, and the focus is on the oil supply and power supply modules.”
……
Although the discussion was about technical issues and no one made any personal attacks, the smell of gunpowder in the words became stronger and stronger. More than a dozen experts present disagreed with each other, and eventually formed roughly four camps and began to argue.
"Well, I am Shen Fei from the secretary's office. Can everyone speak in turn so that I can make a summary of the discussion!"
Shen Fei, who squeezed into the argument, showed an awkward but graceful expression. Smiling, he still had a notebook and pen in his hand, and a voice recorder at work.
There were too many people talking, and the voices overlapped. Even the recorder was too busy, and only the noisy voices were recorded. What was said was completely unclear.
Nangong Chengyu, deputy director of the "Mosasaurus" project, raised his voice and said: "Forget it, let's clarify it again."
At the same time, he looked at General Manager Sun Qiuguo, who nodded.
The girl who just came to them is the deputy general manager of the group company that supports the "Masasaurus" project. Shen Songling's only daughter should be polite in both public and private matters.
“Let’s start from the beginning! Think about it!”
Nangong Ruiyang, deputy general manager of the "Casalong" project and senior engineer of the Northern Ordnance Industry Group, is responsible for aerodynamic control. Pointing to the first expert on his left hand.
“Ge Gong, let’s start with you!”
The expert, who was slightly bald, organized his words and said: "My judgment is..."
Shen Fei's writing skills are very fast. The main content is written down by the recording pen, and then converted into text and exported. All the key points are noted in the book so that it can be presented to Dad for review in a more organized manner.
The secretary’s job is to focus on the key points, simplify the tedious work, distinguish the truth from the false, and help improve work efficiency. He is not responsible for decision-making. At most, he can only provide reference opinions, so the more detailed the work, the better, and the more solid the better. , mastering first-hand information is a must.
The four main judgment directions were put forward one after another, and the atmosphere at the scene became orderly.
I remember that Shen Fei, who was very happy, said casually: "Could it be a problem with the afterburner of the main engine?"
It is the job of experts to judge faults, and Shen Fei's words are a bit like trying to do what they like.
The experts looked at each other and laughed collectively.
Vice President Nangong Chengyu said with a smile: "Huh? Xiao Shen, how did you know?"
He knew that his son Nangong Ruiyang had a crush on Vice President Shen's family This girl, no matter whether she succeeds in the end or not, her attitude at this moment is always much better than others.
It is common for laymen to speak in layman’s terms, which is understandable and does not need to be harshly criticized.
"My friend said that he happened to be passing by when the plane crashed. He guessed that the main engine failed."
Shen Fei recounted Chen Fei's witnessing situation at the time.
Then he pointed to the national highway in the distance, which was parallel to the main take-off and landing runway. The distance seemed to be about two kilometers, but it was still within sight.
An expert shook his head and said: "The guesses of laymen are not enough as a basis. The analysis of the cause of the fault is very rigorous."
Several experts nodded together, although they did not look down on it at all. meaning, but it's true.
There are so many folk mathematics enthusiasts studying several famous mathematical conjectures, but it is still the professional national team that finally succeeds in solving the problem.
Shen Fei’s next answer was beyond everyone’s expectations.
"My friend is an expert. He is a professional fighter maintenance personnel."
"Is he from the maintenance workshop? What is his name?"
Nangong Chengyu is the first The time guess is that it is someone from the group company.
Shen Fei shook her head and said with a smile: "No! He's not from the group company, he's a friend I met when I was teaching."
Sun Qiuguo, the director of the "Mosasaur" project, asked: "Eh? Where? A company? A Boeing aerospace vehicle? Or a Defense Star? "
For a layperson, don’t take it seriously. If you are in the same industry, it’s worth a reference. .
Stones from other mountains can attack jade, and this stone does not come just randomly.
"No, he is a military contractor and an excellent pilot."
Shen Fei didn't know Chen Fei's record, but judging from the attitudes of other people at the 911 air service base, she could guess that he should be doing pretty well.
"Military contractors! There are some masters in this mixed place, both pilots and maintenance personnel. Are they real or fake?"
Although General Manager Sun Qiuguo was a little skeptical, he changed his mind. When I think about it, it is not impossible that the evil capitalists are exploiting people for profit. It is not impossible for one person to act as two people. The so-called "one specialization and multiple abilities" was born to cater to the precise exploitation of capitalists.
Shen Fei guessed and said: "He has a turboprop and jet maintenance qualification certification, so he should be very powerful."
After all, she is a real layman, and she does not know much about it. not much.
"Oh, it's interesting! You can ask him to come and take a look when you have time, if it's convenient."
For the sake of Mr. Shen's daughter, Sun Qiuguo was polite and said this casually.
In any case, the military contractor will not form a competitive relationship with the Northern Ordnance Industry Group, and it is not even possible to have a business relationship. After all, the two sides are completely different worlds, and they cannot even compete with each other.
"Conveniently, he is at Airport 310."
The daughter of the Shen family is so down-to-earth that her words become like a stick.
"Ah? Yes, here?"
310 Airport is also a military base after all. How could it be possible to let people in casually? General Manager Sun Qiuguo was surprised.
Is he not only an employee of a military contractor, but also related to the military?
The experts were collectively stunned.
“He drove me here and let me through directly at the gate. I don’t know why?”
╮（╯＿╰）╭ Shen Fei spread her hands, and there was still a big question mark in her mind until now.
General Manager Sun Qiuguo said: "So that's it. Ask Mr. Shen, if possible, bring your friends over to take a look. It's just a pile of junk anyway, so it doesn't really matter."
< br>Perhaps it really has military connections, otherwise how could it be so simply released.
"Okay!"
Shen Fei turned around and found her father, Shen Songling, the vice president of the group company.
"Mr. Shen!"
"Is something wrong? Secretary Shen!"
Father and daughter are really business-like.
Secretary Shen asked tentatively: "The friend who sent me here may be able to help analyze the cause of the crash. Would you like to invite him to come and take a look."
Shen Songling shook his head. , said angrily: "How can outsiders get involved in company secrets?"
In other words, if my own daughter dared to speak like this, anyone else would have been criticized a long time ago.
"I asked Mr. Sun, and he said we can take a look."
Shen Fei took the chicken feathers as arrows, originally thinking that having one more person would give her more strength. Dad always looked gloomy, so he could guess how big a blow this crash would have on the entire project.
“Nonsense, you are not afraid of leaks of the Mosasaurus project.”
Shen Songling was alert and did not let go easily.
"My friend is a pilot and maintenance technician for a military contractor, and he is also a metal superpower. Don't worry, he is very tight-lipped. By the way, 'Amao' was given to me by him."
In Teacher Shen Fei's impression, Chen Fei has never been a flamboyant person. Instead, he is very calm and low-key, and has always been trustworthy and reliable.
After speaking, he stamped his foot.
“Ah woo!”
The big black-haired wolf sprang out from the shadow under his feet, grinning silly, smelling of hot pot, and adding leftovers. The leftover soup is completely cheap.
"Really special... superpower? Metal superpower?"
Shen Songling finally remembered that she had heard her daughter talk about the young man she met when she was teaching. But what he paid more attention to was his identity as a superpower.
