The engine used by Maifei F435 is a Trent 810 produced by Rolls-Royce.

In the 1990s, several major aircraft manufacturers such as Boeing, Maifei, and Airbus launched their own ultra-large long-range passenger aircraft within a few years in order to compete for the market. As an engine supplier, Rolls-Royce is no less. Through technological reform, it developed a new engine: Trent 810.

At that time, the Trent 810 meant the top engine technology.

It consists of a three-rotor layout and is equipped with the most advanced high-voltage system module, which allows the aircraft to obtain greater thrust while also making it short and light, saving flight costs, so it is very popular.

To this day, the Trent 810 is still one of the best-selling aircraft engines.

Zhuo Huan: "In order to save costs and reduce engine weight, Rolls-Royce reduced the burden on every detail of the engine, including its MCD magnetic chip detector." He seemed to have written a Rolls-Royce engine into a book, and every word was imprinted in his mind. Without reading the manuscript, he blurted out about this complex and huge knowledge. "Normal magnetic chip detectors use conventional physical means, namely magnetic metal."

He took a black oily pen from the table and drew a schematic diagram on the whiteboard.

"When lubricant passes through the oil tank, passes through the return circuit, and passes through the MCD magnetic chip detector, the magnetic chips in the lubricant will be attracted by this magnetic metal. It is like a filter, filtering metal magnetic chip residues that should not exist in the lubricant." Zhuo Huan said, "In order to achieve this, a normal engine must use a main magnetic block and seven secondary magnetic blocks to ensure that the magnetic chips in the lubricant are filtered. However, there is no magnetic block at 810."

Most of the people present were professional aircraft accident investigators, but before checking the information, no one dared to say that they knew the design of the Trent 810 engine.

The only one who can do this is Reid·Irvin·Patrick.

Old Joseph asked: "No magnetic blockage is needed, then what magnetic device does Trent 810 use?"

Zhuo Huan looked at him: "Electromagnetic induction."

There was an uproar.

Zhuo Huan wrote the formula on the whiteboard: "Through precise calculations, the current can pass through the MCD magnetic chip detector, and the electromagnetic effect will generate a powerful magnetic field. This magnetic field is used directly to absorb the floating magnetic chips in the lubricating oil. This measure makes the Trent 810 engine not need to be loaded with any magnetic blockage, which directly saves 6kg of weight costs."

After a pause, he announced in a plain but solemn voice: "This is a genius design."

Instead of using magnets, use electricity directly, generate a magnetic field through electromagnetic induction, and absorb magnetic chips floating in the oil pipe.

This is the realm of God, a design that only geniuses think of.

After hearing this sentence, Old Joseph showed a hesitant look on his face. He seemed to realize something, but he did not say it for a long time. Among all the people present, some people came up with an almost impossible answer, but none of them dared to say it.

Finally, someone couldn't help but speak: "The original design of Trent 810 was to use electricity to create magnetic fields. Are you trying to say that this device has malfunctioned the power system?"

Is this possible?

After years of designing, Rolls-Royce has spent thousands of people on their efforts. They must have conducted countless experimental tests on the MCD magnetic chip detector. More than 20 years have passed, and no accident has happened.

Why did something suddenly happen now?

and……

Old Joseph looked at Zhuo Huan seriously: "What changed this magnetic field and caused the power failure?"

Everything is calculated by scientists and there will be no mistakes.

This MCD magnetic chip detector is filled with the hard work of thousands of designers, and they have carefully calculated every step.

Just like the code written in a computer, the machine is only responsible for calculating the code and will never rewrite the code. Then there must be a mysterious external cause that usurped this line of safe code.

Fucheng's brain started to work quickly, and he thought about every word Zhuo Huan said.

All the investigators present were also thinking wildly, and they whispered to find answers from the collision of inspiration.

At the end, they looked up at the man standing in front of the whiteboard, trying to hear the answer from him.

However, this time, Zhuo Huan put the oily pen back on the table.

He looked down at the small MCD magnetic chip detector on the table: "I'm sorry, I don't know. But what we have to do now is to argue whether the magnetic field of the MCD magnetic chip detector will change under the action of the external magnetic field; if it changes, will this change react and affect the aircraft's power system."

"Everyone-"

"That's what we'll do next."

The Rolls-Royce company members arrived at the investigation headquarters that afternoon.

The name Rolls-Royce is not unfamiliar. As we all know, it is one of the world's top luxury cars.

In fact, it is indeed that Rolls-Royce.

Rolls-Royce is divided into two parts, one of which produces Rolls-Royce cars and the other produces aircraft engines. In order to facilitate distinction, the latter is also called Rolls-Royce engine.

Researchers from Rolls-Royce engines came to the investigation headquarters to assist UAAG in engine troubleshooting.

After the other party arrived, he said directly: "Science always staggers and struggles through repeated mistakes. Failure is the only way to success. Rolls-Royce is very happy to cooperate with the investigation, but we do not think it is an engine failure."

"The MCD magnetic chip detector of Trent 810 has never had any failure after 3,176 experiments in our laboratory."

"The magnetic field of the magnetic chip detector is provided by the power system. If its magnetic field changes, it must be that the power system changes first. This is a chicken and egg problem. If the power system does not make any mistakes, the magnetic field will not make any mistakes. So in the final analysis, it will not be a problem with the engine itself."

Zhuo Huan: "Where is the designer of this MCD magnetic chip detector now?"

The researcher sent by Rolls-Royce was choked by a word. He didn't expect that he had said so much, and the other party ignored him at all. But thinking about who the person in front of him was, he could only forgive the arrogance of this person.

"Because of limited personal abilities, Rolls-Royce fired the designer twelve years ago."

Zhuo Huan said "tsk", he turned his head and wanted to speak, but found that Lina was standing next to him.

With his eyebrows frowned, Zhuo Huan called Fucheng, who was carrying a JAL JL917 flight map for research. After he arrived, he asked Lina to tell him what had happened here just now, and then said to Fucheng: "Look, I said that geniuses are always lonely."

Unexplained Rolls-Royce personnel: "…?"

Fucheng: "..."

Rolls-Royce researchers firmly believe that it is definitely not a problem with their engine.

The engine's magnetic field is all provided by the aircraft's power system. If the power system does not go wrong, the engine's magnetic field cannot go wrong.

However, Zhuo Huan did not give them any chance to defend themselves.

Everyone put a new Trent 810 MCD magnetic chip detector in the laboratory, and applied a special magnetic field to it from the outside, constantly changing the direction and intensity of the magnetic field. After only 37 experiments, the conclusion was drawn.

Old Joseph smiled and said, "It is obvious that when the magnetic field of the MCD magnetic chip detector is affected externally, as long as the magnetic field is greater than 156 Gauss and the direction angle is greater than 18.6 degrees, the original magnetic field of the magnetic chip detector will be changed; when the magnetic field strength is greater than 865 Gauss, it will react and affect the power system, overload the aircraft's power system, causing a brief downtime, that is, a crash."

The Rolls-Royce researchers' faces changed, but he quickly calmed down and asked with a smile: "Where can we obtain the external magnetic field of 865 Gauss?"

The smile on Old Joseph's face gradually disappeared.

The magnetic field of 865 Gauss is very small in the laboratory. The magnetic field strength of a permanent magnet is 1,000 Gauss.

But on the plane, where can we find such a magnetic field without any external force?

Old Joseph couldn't help but turn his head and look at Zhuo Huan.

Under the clear moonlight, the man looked at them calmly, took off his laboratory white coat and placed it on the back of the chair. Instead of speaking, he turned around and pressed the button of the laboratory glass door and walked out strode.

Through the window, a little sparks lit up in the quiet night.

Leaving the laboratory, Zhuo Huan and Joseph the old returned to the investigation headquarters.

Everyone looked at them expectantly and waited for them to give the final experimental results.

Old Joseph said bitterly: "Indeed, the external magnetic field can change the electromagnetic field of the MCD magnetic chip detector. After reaching 865 Gauss, it will affect the power system and cause downtime. But where can I find this external magnetic field?"

Everyone looked disappointed.

After Zhuo Huan returned to the investigation headquarters, he searched for relevant papers in front of the computer.

He wrote unhappy on his left face, and very annoyed on his right face. Four words were printed on the top of his head.

Don’t be close to a new person.

The terrifying low pressure was irresistible, and the army was in a mighty and overturned, oppressing the entire investigation headquarters so that no one dared to speak out.

Su Fei was hiding behind the computer and quietly looked at the big devil, when suddenly a figure flashed in his aftermath.

Su Fei raised his head: "Hey, don't go, don't pay attention to him! Come back!"

The light was blocked by someone's figure, and Zhuo Huan slowly raised his head and saw the person coming.

Zhuo Huan: "Hmm?"

Fucheng put a piece of information in front of him: "On December 19, 2019, JAL JL917 took off from Tokyo and flew to Helsinki, Finland. On the night of flying to the Arctic Circle, the Arctic Circle broke out in an aurora craze that had been seen in 38 years. According to eyewitness records, the aurora exploded 73 times at the same location, which only happened within two hours."

His lips opened slightly, and Zhuo Huan looked at the young black-haired man in front of him, and suddenly he couldn't say a word.

Fucheng: "I read the interview reports of 89 survivors on board, and 65 of them reported that they saw the aurora while flying—"
