The engine used by McFly F435 is the Trent 810 produced by Rolls-Royce.
In the 1990s, Boeing, McFly, Airbus and other major aircraft manufacturers launched their own ultra-large long-range passenger aircraft within a few years in order to compete in the market. As an engine supplier, Rolls-Royce did not give up much. Through technological reforms, it developed a new type of engine: the Trent 810.
At the time, the Trent 810 meant state-of-the-art engine technology.
It consists of a three-rotor layout and is equipped with the most advanced high-voltage system modules, which enables the aircraft to obtain greater thrust while being short and light, saving flight costs, so it is very popular.
Today, the Trent 810 remains one of the best-selling aircraft engines.
Zhuo Huan: "In order to save costs and reduce the weight of the engine, Rolls-Royce has lightened every detail of the engine, including its MCD magnetic chip detector." He seemed to write a Rolls-Royce engine as Every word of the book is printed in my mind, without reading the manuscript, I can blurt out this complicated and huge knowledge, "Normal magnetic chip detectors use conventional physical methods, that is, magnetic metals."
Taking a black oil-based pen from the table, he drew a diagram on the whiteboard.
"When the lubricating oil passes through the oil tank, through the oil return line, and through the MCD magnetic chip detector, the magnetic chips in the lubricating oil will be attracted by this piece of magnetic metal, which acts like a filter, filtering out what should not be in the lubricating oil. Metal debris residue.” Zhuo Huan said, “In order to achieve this, a normal engine needs to use one main magnetic plug and seven auxiliary magnetic plugs, so as to ensure the filtration of magnetic chips in the lubricating oil. But the Trent 810 has a magnetic plug nothing."
Most of the people present were professional aircraft accident investigators, but no one dared to say that they knew the design of the Trent 810 engine before consulting the information.
Can do this, only Reid·Irvin·Patrick.
Old Joseph raised a question: "There is no magnetic plug, so what kind of magnetic device does the Trent 810 use?"
Zhuo Huan looked at him: "Electromagnetic induction."
There was an uproar.
Zhuohuan wrote down the formula on the whiteboard: "Through precise calculation, when the current passes through the MCD magnetic chip detector, a strong magnetic field is generated due to the electromagnetic effect. This magnetic field is directly used to absorb the magnetic chips floating in the lubricating oil. This This measure makes the Trent 810 engine unnecessary to load any magnetic plug, directly saving 6kg in weight cost.”
After a pause, he announced in a flat but solemn voice: "This is a genius design."
Instead of using magnets, electricity is used directly, and a magnetic field is generated through electromagnetic induction to absorb magnetic chips floating in the oil pipe.
This is God's domain, a design that only geniuses can come up with.
After hearing this sentence, old Joseph showed a hesitant look on his face. He seemed to realize something, but he didn't say it for a long time. And among all the people present, someone came up with an almost impossible answer, but none of them dared to say it.
Finally, someone couldn't help but say, "The original design of the Trent 810 was to use electricity to create a magnetic field. Are you trying to say that this device has malfunctioned on the power system instead?"
is it possible
Rolls-Royce has been designed for many years and thousands of people have spent their efforts. They must have done countless experimental tests on the MCD magnetic chip detector. More than twenty years have passed, and no accident has happened.
How could something suddenly happen now
and…
Old Joseph looked at Zhuo Huan seriously: "What changed this magnetic field and caused the power failure?"
Everything has been calculated by scientists, and there will be no mistakes.
This MCD magnetic chip detector is the painstaking effort of thousands of designers, who have carefully calculated every step.
Just like the code written in the computer, the machine is only responsible for calculating the code, and will never rewrite the code. Then there must be a mysterious external factor tampering with this line of safe code.
Fucheng's brain started to work quickly, he thought about every sentence, every word Zhuo Huan said.
All the investigators present were also thinking frantically, discussing in low voices, trying to find answers from the collision of inspirations.
In the end, they looked up at the man standing in front of the whiteboard, hoping to hear an answer from him.
But this time, Zhuo Huan put the oil-based pen back on the table.
He looked down at the small MCD magnetic chip detector on the table: "Unfortunately, I don't know either. But what we have to do now is to demonstrate—under the action of the external magnetic field, whether the magnetic field of the MCD magnetic chip detector There will be changes; if there is a change, will the change be reversed and affect the aircraft's electrical systems."
"Everyone—"
"That's our next task."
People from Rolls-Royce arrived at the investigation headquarters that afternoon.
The name Rolls-Royce is not unfamiliar to anyone. As we all know, this is one of the top luxury cars in the world.
In fact, it really is that Rolls-Royce.
Rolls-Royce is divided into two major parts, one part produces Rolls-Royce cars and the other part produces aircraft engines. For the convenience of distinction, the latter is also called Rolls-Royce engine.
Rolls-Royce engine researchers came to the investigation headquarters to assist UAAG in troubleshooting the engine.
After the other party arrived, he said directly: "Science always stumbles forward amidst mistakes again and again. Failure is the only way to success. Rolls-Royce is very happy to cooperate with the investigation, but we don't think it is Engine failure."
"The Trent 810's MCD magnetic chip detector has been tested 3176 times in our laboratory and has never had any failure."
"The magnetic field of the chip detector is provided by the power system, and if its magnetic field changes, it must have changed in the power system first. It's a chicken-and-egg problem. If there is nothing wrong with the power system, the magnetic field will not." Mistakes. So at the end of the day, it’s not the engine itself.”
Zhuo Huan: "Where is the designer of this MCD magnetic chip detector?"
The researchers sent by Rolls-Royce choked on a single sentence. He didn't expect that after he said so much, the other party ignored him at all. But thinking about who this person is in front of him, he can only forgive this person's arrogance.
"Because of limited personal ability, Rolls-Royce fired the designer twelve years ago."
Zhuo Huan gave a "tsk", he turned his head to speak, and found Lina standing beside him.
Frowning, Zhuo Huan called to Fucheng who was holding a Japan Airlines JL917 flight map for research. When he came, he asked Lina to tell him what happened here just now, and then said to Fucheng: " You see, as I said, a genius is always alone."
Unidentified Rolls-Royce staff: "...?"
Fucheng: "..."
The Rolls-Royce researchers are adamant that there is absolutely nothing wrong with their engine.
The magnetic field of the engine is all provided by the electrical system of the aircraft. If the electrical system does not go wrong, the magnetic field of the engine cannot go wrong.
However, Zhuo Huan didn't give them a chance to defend themselves.
Everyone put a new Trent 810 MCD magnetic chip detector into the laboratory, applied a special magnetic field to it from the outside, and constantly changed the direction and strength of the magnetic field. After only 37 experiments, a conclusion was drawn.
Old Joseph smiled and said: "Obviously, when the magnetic field of the MCD magnetic chip detector is affected by the outside, 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 If it is greater than 865 gauss, it will adversely affect the power system, overload the aircraft power system, and cause a short-term downtime, that is, a crash."
The face of the Rolls-Royce researcher was fluctuating, but he quickly calmed down and asked with a smile, "Where do you get the external magnetic field of 865 Gauss?"
The smile on old Joseph's face faded away.
The magnetic field of 865 gauss is almost negligible in the laboratory, and the magnetic field strength of a permanent magnet is 1000 gauss.
But on the plane, without any external force, where to find such a magnetic field
Old Joseph turned his head involuntarily and looked at Zhuo Huan.
Under the frivolous moonlight, the man glanced at them indifferently, took off his white laboratory coat, and put it on the back of the chair. He didn't speak, but turned around and pressed the glass door button of the laboratory, and strode out.
Through the window, a little spark lit up in the silent night.
After leaving the laboratory, Zhuo Huan and Old Joseph returned to the investigation headquarters.
Everyone looked at them expectantly, waiting for them to give the final experimental results.
Old Joseph said with a wry smile: "It is true that the external magnetic field can change the electromagnetic field of the MCD magnetic chip detector. When it reaches 865 Gauss, it will affect the power system and cause downtime. But where do you find this external magnetic field?"
Everyone showed disappointed expressions.
After Zhuo Huan returned to the investigation headquarters, he searched for relevant papers in front of the computer.
He was unhappy on the left side of his face, and very irritable on the right side. There are four words printed on the top of the head——
Strangers stay away.
With an unstoppable force, the terrifying low air pressure sent a mighty army rolling down, oppressing the entire investigation headquarters so that no one dared to speak out.
Su Fei was hiding behind the computer and quietly looking at the Great Demon King, when suddenly a figure flashed in his peripheral vision.
Su Fei raised his head: "Hey, don't go, ignore him! Come back!"
The light was blocked by the figure of a person, Zhuo Huan raised his head slowly and saw the person coming.
Zhuohuan: "Huh?"
Fucheng put a piece of information in front of his eyes: "On December 19, 2019, Japan Airlines JL917 took off from Tokyo and flew to Helsinki, Finland. On the night of the flight to the Arctic Circle, the Arctic Circle erupted a frenzy of aurora once seen in 38 years. According to eyewitness records, at the same location, the aurora exploded 73 times, which occurred within only two hours."
With his lips parted slightly, Zhuo Huan looked at the black-haired young man in front of him, and suddenly couldn't say a word.
Fucheng: "I read the interview reports of the 89 survivors on the plane, and 65 of them reported that they saw the aurora while the plane was flying—"
"It was a nice day in Finland, but unfortunately, in the Arctic Circle, it doesn't seem to be."
