The biggest difference between civilian engines and military engines lies in the design of the afterburner structure.
There is no afterburner in the former. 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 combat 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. A too long design life will lead to high costs and will also affect the performance of active equipment.
It changes from generation to generation, 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. It has a wide range of applications, large output, and low maintenance costs.
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 attributed the cause of the crash to afterburners, that is, the main engine part, 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 layman he was at the beginning.

After the No. 2 prototype of the "Masasaurus" project crashed to the ground, the debris was scattered up to a kilometer away, almost reaching the living area and administrative area of the airport. Multiple drones kept flying around, scanning the ground repeatedly.
Search for wreckage fragments, generate scatter point plan, and simultaneously search for airborne black boxes.
Even if the plane crashes, as a valuable experience from which lessons can be learned, naturally not even a single fragment should be let go.
The drone recognized the black box with some orange-red residue. However, even with special protection design, it is not 100% foolproof.
The found black box was not only torn into pieces, but even the backup memory chips were all burnt.
There was an uproar within 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 the light of elemental energy collapse when the machine lost control."
"The data that was finally flattened was a bit abnormal. It may also be that the electronic system failed and there were technical defects in the control system."
"How could it be the control system? The control system of the '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, could it be a human error? Where is the test pilot? What is the condition of the test pilot?"
"My thigh was broken when I landed, and I'm undergoing surgery... I'm afraid we won't be able to talk to you until the day after tomorrow at least."
"Let's check other problems first! Before the energy of the elemental system collapsed, the machine started to smoke. Focus on checking the fuel supply and power supply modules."
…
Although the discussion was about technical issues, no one made any personal attacks, but the smell of gunpowder in the discourse became stronger and stronger. More than a dozen experts present disagreed with each other, and eventually formed roughly four camps and began to argue endlessly.
"Um, I'm Shen Fei from the secretary's office. Can you all speak in turn so that I can make a summary of the discussion!"
Shen Fei, who had squeezed into the argument, smiled awkwardly but gracefully. She still had a notebook and pen in her 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 who 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 director of the "Mosasaur" project and senior engineer of the Northern Ordnance Industry Group, responsible for aerodynamic control, pointed to the first expert on his left hand.
"Ge Gong, let's start with you!"
The expert with half-bald hair organized his words and said: "My judgment is..."
Shen Fei's writing memory is very fast. The main content is written down with a voice recorder, and then converted into text and exported. The key points are recorded in the notebook so that it can be presented to dad for review in a more organized manner.
The job of a secretary is to focus on key points, simplify trivial matters, distinguish authenticity from falsehood, and help improve work efficiency. He is not responsible for decision-making and can only provide reference opinions at most. Therefore, the work must be as detailed as possible, the more solid the better, and master first-hand information.
is required.
The four main judgment directions were put forward one after another, and the atmosphere at the scene became orderly.
I remember Shen Fei, who was very happy, casually said: "Could it be a problem with the main engine afterburner?"
It is the job of experts to judge faults, and what Shen Fei said is 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 fallen in love with this daughter of Vice President Shen's family. No matter whether he succeeded in the end or not, his attitude at this moment was always much better than others.

"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 status 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 visual distance.
An expert shook his head and said: "Layers' guesses are not enough to provide a basis. Analysis of the cause of the failure is very rigorous."
Several experts nodded together. Although they didn't mean to look down upon it, it was a fact.
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 aircraft maintainer."
"Are you from the maintenance shop? What's your name?"
Nangong Chengyu immediately guessed that he was 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? Which company? Dragoon Magic Industry? Boeing Aerospace? Air combat vehicle? Or the National Defense Star?"
Just listen to what a layman says and don’t take it to heart. If you are in the same industry, it can be a reference.
Stones from other mountains can be used to attack jade, but this stone did 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 was 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 had some doubts, he thought about it. The evil capitalists are exploiting people for profit. It is not impossible for one person to work as two people. The so-called "one specialty, multiple abilities" was born to cater to the precise exploitation of capitalists.
of.
Shen Fei guessed and said: "He has turboprop and jet maintenance qualification certification, so he should be very capable."
After all, she is a true layman and doesn't know much.
"Oh, that'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, military contractors 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 climbing a stick.
"Ah? 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 has something to do with 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 even now there is still a big question mark in her mind.
Sun Qiuguo, the general manager, 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."
Maybe it was really related to the military, otherwise how could he be let go so easily?
"OK!"
Shen Fei turned around and found her father, Shen Songling, the vice president of the group company.
"Mr. Shen!"
"Is something wrong? Secretary Shen!"
The 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 and 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 about it, and he said I could take a look."
Shen Fei used chicken feathers as arrows. She originally thought that having one more person would give her more strength. Seeing her father's frown all the time, she guessed how big a blow this crash would have on the entire project.
"Nonsense, you are not afraid of leaks about 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 saying that, he stamped his foot.
"Aww!"
The big black-haired wolf sprang out from the shadow under his feet, grinning silly, smelling strongly of hot pot, and it was all worth it with the leftover rice and leftover soup.
"Zhente... superpower? Metal superpower?"
Shen Songling finally remembered that he had heard his daughter talk about the young man she met when she was teaching.
But what matters more to him is his identity as a superpower.
