UAAG Air Crash Investigation Team

Chapter 50

Views:

In the dimly lit room, the air froze for a moment.

Fu Cheng pursed his lips and looked away awkwardly.

The person who was stared at did not respond, his gaze stayed on the young man's stiff side face for a few seconds, and a teasing look flashed in Zhuohuan's eyes. He leaned over and said softly, "What did you see?"

Fucheng: "..."

Zhuo Huan: "I'm at a disadvantage."

Fu Cheng still bowed his head and did not answer.

Zhuo Huan smiled, and stopped teasing this person, he freed his hands and started typing on the keyboard. While typing, he said: "If you really want to rely entirely on calculations to calculate the specific location of Roger 318 Aviation, the possibility is infinitely close to zero."

Fu Cheng turned his head: "Then you said just now that you want to figure out where Rogge 318 is."

Really interested in this

This sentence flashed through his mind, Zhuo Huan gave a soft "hmm" without turning his head to look at the young man lying beside him, and continued to type: "Find out where it is, which means figure out its approximate location. Do you know how big the Pacific Ocean is? Without letting Fucheng answer, he continued: "181.34 million square kilometers. Do you know what this is? The global land area is about 149 million square kilometers. Even if you exclude most of the Pacific Ocean... Well, a plane No matter how the plane moves with the ocean current, it is impossible to float from Canada to Australia."

"Only counting the waters near the west coast of Canada, the NTSB's salvage area for the aircraft is 5 million square kilometers."

"It's half the size of Huaguo."

Pressing the "Enter" key, Zhuo Huan turned around and looked at Fu Cheng: "Can you find a plane in half of the map of Huaguo?"

Fu Cheng: "... Impossible."

"Yeah, even you know it's impossible."

Fu Cheng frowned: Even you

Zhuo Huan seemed unaware of his own sarcastic words, he stretched his neck and lazily said: "So, through calculation, narrow down the range. When the range is reduced to only 10,000 square kilometers... it will definitely be found. "

After a while.

Fucheng: "After you announced the stop of the investigation, have you been doing this alone, Mr. Zhuo?"

Zhuo Huan: "One person? Of course not. I am not a professional marine expert, ocean current movement expert, or meteorological expert... I have a specialization in technology, and there are several people who do this together." He raised his eyebrows, a little surprised: "I just now Just emailing Robert Gatsby, didn't you see? Don't you know him?"

Fucheng: "..."

"Should I know?"

Qingche's long and narrow eyes slowly widened, and after a while, Zhuo Huan said, "Oh, he won the Nobel Prize in Physics in 2006. His laboratory runs the supercomputer at the University of California, San Diego. All our data After the preliminary calculation, he will input it into the supercomputer for the final calculation."

Fu Cheng: "...um."

Zhuo Huan laughed out loud.

Fucheng got up from the bed expressionlessly, picked up the trousers that fell on the floor, and handed them to someone.

The man lying on the bed didn't intend to take it, but hooked the corner of his mouth instead: "Before you put on pants, didn't you wear underwear?"

Fucheng: "..."

Another email came, Zhuo Huan immediately looked at the computer. Without raising his head, he commanded Fucheng: "Bring a pair of clean underwear from my box, where is the box... eh? Businiske's equation repeats..." He put down his laptop and found himself under the quilt I don’t know where to throw the mobile phone, I pulled out a number and called out: “Robert, um, it’s me. If we re-deduce, the eddy viscosity parameter in the equation is under the condition that the upwelling density changes and the temperature difference is too large…”

Fu Cheng walked out of the room, came to the living room, and found the suitcase leaning against the corner. He took a pair of clean underwear from inside, and when he returned to the room, Zhuo Huan was leaning against the head of the bed with his upper body bare, the quilt was casually covering his waist, and one leg was stretched outside the bed. Seeing Fucheng come in, he reached out, took the underwear in his hand, then lifted the quilt, and put it on directly.

"The calculation is abnormal, consider the problem of the eddy viscosity parameter, my suggestion is..."

Putting on his pants, he took a clean T-shirt from the sofa and put it on roughly.

When Zhuo Huan hung up the phone, it was already five minutes later.

Fu Cheng looked up at him: "I've told Lina to let them go first, we'll take a taxi there later."

Zhuo Huan was taken aback for a moment, he turned his head sideways and looked at the young man in front of him. "Do you want to do something with me?"

Fucheng did not reply to him, but said: "Professor Robert Gatsby, I just checked his information on Google, he is a very powerful physicist."

Zhuo Huan laughed: "I'm not great."

After a moment of silence, Fu Cheng looked at Zhuo Huan: "Mr. Zhuo, can you find it?"

The clean and beautiful pupils of the young man reflected a clear and bright color, it was quiet and peaceful, but silent, just looking at Zhuo Huan without blinking. Obviously there are many answers, you can just find one and answer this question. But Zhuohuan's heart moved slightly, the young man's expression was calm and calm, but he could see the stubbornness and firmness like a stubborn bamboo.

After a long time, Zhuo Huan: "When you look for a lost thing, do you always think about finding it right away?"

Fu Cheng: "No."

Zhuo Huan stepped on the carpet with bare feet, and walked to Fu Cheng's side, he bent slightly, Fu Cheng held his breath.

Passing over the young man, he took away a watch that was placed on the chair behind Fu Cheng. It was the piece given to him by the three of Fucheng when he celebrated his birthday last week.

Standing up straight and fastening the watch, Zhuo Huan stretched out his hand, and he lifted Fu Cheng's chin with his fingers, forcing him to look at him.

The man's voice was low and sweet, every inch of it, and he spoke in an ambiguous hoarse voice.

"It's like I did a lot of things before I fell for you. These things seem meaningless, and none of them will make me fall for you immediately... But the result is inevitable. I will fall for you, and I will Logue 318 will be found."

Looking at each other, Zhuo Huan quietly looked at the young man looking up at him, but he couldn't see any emotion from his calm eyes.

He laughed, let go of the hand holding Fu Cheng's chin, put on his shoes and walked to the bathroom.

Zhuo Huan: "Let the front desk find a car first, I'll be fine soon."

Fu Cheng: "Yes."

The moment the bathroom door was closed, the young man's originally calm expression suddenly cracked. The hand holding the phone trembled slightly, and the roots of his ears inevitably turned red. His chest was heaving up and down, but he still tried his best to maintain a calm expression on his face. He gasped slightly, and then buried his face in his palms.

Ten minutes later, the two went out together.

When she arrived at the investigation headquarters, Lina was watering the flowers.

Zhuo Huan: "When did you buy the flowers?"

Lina smiled softly: "I bought it on the first day I came here. Reid, this is called the joy of life. In the past, you didn't have a pair of eyes to discover beauty, so you couldn't see it. I am very happy, today you have such a pair of eyes. It's a pity that you You can find beauty, but correspondingly, you lose your aesthetics." She pointed to the watch on Zhuo Huan's wrist, "Patek Philippe doesn't deserve a T-shirt at all, especially this one on you."

Zhuo Huan didn't take it seriously, and took a cup of coffee casually: "I don't wear it to show you, but to show others."

Lina raised her slender brows, she saw Fu Cheng also entered the door, she said to Fu Cheng: "Fu, Reid said that he didn't wear it for me, but did he wear it for you?"

Fu Cheng looked sideways at Zhuo Huan: "Mr. Zhuo, is this a cold joke?"

Zhuo Huan: "You say it is so it is."

Fu Cheng: "Oh, that's not very funny."

Zhuo Huan glanced at him, and said to Lina: "In an hour, call them for a meeting and officially start the investigation."

Lina: "OK."

An hour later, the GCAA surveys headquarters, conference room.

Old Joseph stood in front of the large whiteboard and explained the details of the Emirates 411 crash to all the investigators present. Since everyone has read all the 96 boxes of investigation materials, Old Joseph spoke very easily, and no one raised any doubts.

After the speech, Lina said: "GCAA contacted NTSB at noon yesterday and told them about the situation. As far as I know, NTSB sent people this morning and should arrive in Dubai tomorrow. Reid, they brought the information here."

Zhuo Huan: "OK, what happened to the wreckage of the plane." He looked at Fu Cheng.

Fucheng and Maiha glanced at each other, and the latter brought up a large cardboard box from under the table.

Fucheng Road: "The Emirates 411 crash was an accident 23 years ago. The wreckage of its plane was destroyed and almost shattered due to the violent explosion. Therefore, the GCAA did not completely preserve the wreckage of the plane at that time, only the engine Part of it, that's what you can see now. That's all that's left of the right hand engine, and after the explosion ... that's all there is to it."

Inside the box was a transparent rectangular parallelepiped glass box, inside which was placed a black metal object with a length, width, and height of 30 cm. It was scorched black all over and exploded badly. Even Zhuo Huan looked at it for a minute, but couldn't recognize which part of the engine it belonged to.

Maiha said: "Emirates is the best airline in our country. The 411 crash was the worst and most serious accident since their establishment. Emirates has assured me that it will fully support the re-investigation of the accident. They also want to Know the truth." After a pause, he added, "This full support includes financial support."

Zhuo Huan raised his eyebrows: "Including a Boeing 777 for research?"

Maiha was stunned: "This, this... I'm not sure about this. But I can contact the person in charge over there and ask him if it's okay."

Zhuo Huan: "Then you go to contact now."

Maiha: "Huh?" He thought Zhuo Huan was joking.

Zhuo Huan: "Doesn't full support include giving a Boeing 777?"

It was only then that Maiha knew that Uncle Zhuo was serious about asking Ah Hang for a Boeing 777 for research. With a complicated expression, he nodded and stood up: "I'll call over there right away."

Everyone present: "..."

As if he didn't think there was anything wrong with asking for a plane worth over 100 million yuan, Zhuo Huan stood up, walked to the whiteboard, and wrote down a word—

"Shards".

"The people from NTSB have not arrived, nor has the Boeing 777 provided by Emirates..."

Everyone: "..."

Are you so sure that Emirates will give you a Boeing 777 to study casually!

Who gave you confidence!

Zhuo Huan continued: "First of all, we need to determine the sequence of time. It was the palm-sized debris on the right flap that flew out of the fuselage first; then, the fan blades suddenly broke in the low-pressure chamber of the right engine. .Or at least, these two things can happen at the same time, but it is absolutely impossible that the latter happened first."

"Then here comes the problem..."

"Under what circumstances, a Boeing 777 that has only been in use for one year will have damage to the metal material on the surface of the flap."

"That's what you're going to find out."

"Okay, the meeting is over."

***

Zhuo Huan announced the mission to investigate the headquarters, and everyone began to study this issue.

Su Fei thought for a long time, and suddenly said: "I thought of it."

Everyone in UAAG looked at him in unison.

The punk boy is no longer as rebellious and individual as when we first met. He took off three earrings on his ears, leaving only one with a black skull. At this moment, he touched the black skull on the earlobe, coughed, and said: "I declare in advance, I am still young, I am underage, and I am inexperienced! I am just making a guess, don't laugh if I am wrong!"

Everyone: "I'm not laughing at you."

Su Fei was excited and enthusiastic: "The simplest answer to this question is that there is a maintenance error!"

Fu Cheng frowned slightly.

Su Fei said: "Last year's Martha Airlines 123 crash, didn't it mean that there was a problem with the aircraft maintenance, and a screwdriver of the wrong size was used, which eventually caused the aircraft to fly in mid-air and the tail suddenly fell off? Sorry, Lina, I didn't mean to mention It breaks your heart, and I'm just giving you an example."

Lina shook her head: "It's okay."

Old Joseph smiled slightly, and touched his chin: "The answer you said is actually the most likely."

Su Fei's eyes lit up: "Really!"

Old Joseph: "In 1989, United Airlines 232 crashed. A DC-10 plane bound for Chicago from Denver crashed in Sioux City. The cause of the accident was that the engine fan blades suddenly broke, cutting off the tail and all the hydraulic systems on the plane. …Oh, the breakage of the fan blade is not a maintenance error, but a flaw in the beginning of manufacture. But you said that the maintenance error caused the metal material on the surface of the aircraft to peel off, which is very likely.”

Encouraged, Su Fei nodded and said, "Hearing what you said, I think I make more sense. You see, the chronological order of things is like this. First, the metal surface of the flap peeled off, and then it flew away. Well, actually! It didn't really fly away, it went under the plane and got caught in the engine!"

Old Joseph clapped his hands: "And then this piece of debris cut the blades of the low-pressure fan of the plane, and finally caused the air crash?"

Su Fei: "Yes!"

Fucheng said helplessly, "Stop teasing him, Old Joseph."

Old Joseph laughed.

Su Fei: "... ???"

Su Fei is a computer major, and no one knows why he, a nominee for the Turing Award, was involved in the investigation of aircraft accidents, and he has such advanced research on black boxes. But there is no doubt that he doesn't know much about the aircraft itself, and most of what he knows is what he has learned and sold in the past six months.

Fucheng explained: "The air crash in Sioux City was caused by a broken fan blade, which cut off the tail. But your guess is wrong. The low-pressure fan can fly out of the engine, but nothing can fly into the engine and cut off its low-pressure fan. Because it is passing through the engine. It must have been burnt to ashes by the time the fuel chamber was opened." The voice paused, and Fushiro concluded: "In short, it is absolutely impossible for the fragments peeled off from the flaps to cause the engine fan blades to break."

Su Fei: "..."

The punk boy turned his head and glared at Old Joseph: "You are laughing at me on purpose!"

Old Joseph was innocent enough.

Fu Cheng: "Actually, Su Fei's guess is indeed the most likely reason."

Everyone looked at him together.

Fucheng pondered for a while, and said: "The most likely reason for the peeling of the outer surface of an aircraft is of course a problem with its own quality. For example, manufacturing defects like the Sioux City air crash, or Martha Airlines Flight 123, where the wrong aircraft was used for maintenance. Screws. The former is Boeing's manufacturing issue, the latter is Emirates' maintenance issue. Well, it's definitely not an Emirates maintenance issue, only possibly Boeing's manufacturing issue."

Su Fei asked in surprise, "Why isn't it the maintenance problem of Emirates Airlines?"

Before Fucheng could speak, Lina smiled first: "Su Fei, do you know the top ten safest airlines in the world?"

Su Fei shook his head.

Lina: "Emirates ranks in the top three. Aircraft accidents are unavoidable, and no one dares to say that there will be no accidents. It is absolutely impossible to prevent air accidents. But it is not impossible to reduce the probability of air accidents. Money is a good thing." thing."

Fucheng nodded: "All civil aviation pilots in the world know that the happiest pilots in the world are the pilots of Emirates Airlines. Do you know the average age of the aircraft of Emirates Airlines?"

A cold male voice sounded not far from the crowd: "How much?"

Unexpectedly, Zhuo Huan would be interested in this, Fu Cheng was stunned, and turned to look at him: "55 months."

Zhuo Huan was stunned.

Old Joseph whistled directly.

Su Fei: "Damn it, 55 months? 4 years and 7 months?!"

Fucheng nodded: "Well, it is 4 years and 7 months. First of all, it is absolutely impossible for Emirates to have second-hand planes. They will not buy obsolete planes from any other airlines. All the planes they use are from Boeing. , McFly, and Airbus directly ordered. There are no small planes, but all large planes. Secondly, from the time an aircraft enters the tarmac of Emirates to being sold by Emirates, it takes an average of 4 years and 7 months. Aircraft Of course, the service life of the aircraft is not only 55 months, it can be used for ten, twenty, or even thirty years without any problem. But there is no doubt that the safety index of new aircraft is always more reliable than that of old aircraft.”

Su Fei: "I understand. Therefore, if you are willing to spend money to phase out an aircraft every four years, Emirates Airlines must be willing to spend a lot of money to repair the aircraft. It is absolutely impossible to be greedy for cheap... How much money does it cost? capitalists!"

Fucheng: "You can't say that. If you are a complete capitalist, you will not be willing to spend so much money to buy and repair aircraft. For example, American Airlines and Japan Airlines, if there is a maintenance problem with the aircraft, there are two options - to buy new parts. , continue to maintain. They will definitely choose the latter. Because the former costs millions or even tens of millions of dollars, but the latter is a hundred times cheaper. But Emirates is different. Similarly, when I was in Donghua Airlines, Donghua Airlines also in this way."

Old Joseph glanced at him, and couldn't help agreeing: "Although I used to be a pilot of American Airlines, I agree with you. The airlines in China are really willing to repair aircraft, and the age of aircraft is generally very short. , not much longer than Emirates. It’s well known in the industry.”

Fucheng smiled and said: "So there are very few air accidents in our country. Because in Hua country, human life is more important than the sky. I would rather spend tens of millions or hundreds of millions in normal times than have an air crash. There are many reasons behind this, but no matter what , Its ending is good, Huaguo's plane is safe."

Back to the topic, Old Joseph coughed and stopped teasing Su Fei. "If it's just the material peeling off the outer surface of the flaps, I believe it may be a Boeing manufacturing problem. If it's just the engine blades breaking, I also believe it may be a Rolls-Royce manufacturing problem. But now the two happened together..."

Everyone was lost in thought again.

Fu Cheng turned around quickly: "Mr. Zhuo, do you have any ideas?"

Zhuo Huan sat by the window, chewing gum while staring solemnly at the three-dimensional structure diagram of Boeing 777 on the computer screen. When someone mentioned his name suddenly, he raised his head and looked at Fucheng.

Their eyes met in the air.

Zhuohuan twirled the pen in his finger, smiled casually: "You four, I alone... Now, you ask me?"

Lina raised her hand and said with a smile: "I don't count, I don't understand anything, non-staff."

Su Fei hurriedly pulled the chair and sat back: "Don't count me in, I'm underage, I'm still a child!"

Zhuo Huan raised an eyebrow, but he still didn't answer directly, but asked Fu Cheng: "What do you think?"

Fucheng thought for a long time, and said seriously: "Two things, only one happened, and there are many reasons. But two things happened at the same time, I think... the reason for the cracking of the flap surface and the breaking of the engine fan blade must be It's the same."

Old Joseph's eyes lit up: "The same thing, split the outer surface of the plane and the engine? In 2000, Air France 4590 crashed, a supersonic Concorde just took off, the left engine caught fire and finally crashed. After the accident investigation It turned out that the previous plane dropped a long piece of metal and left it on the runway. It split the tires of Air France, and the tire fragments split the fuel tanks and cables, which eventually caused the fire..." Just finished speaking, old Joseph He was stunned for a while, and he shook his head: "No, Emirates 411 caught fire suddenly in the air, and it has nothing to do with the previous plane."

Fucheng: "In fact, before 411 took off, the runway also went through a detailed inspection, and there were no foreign objects left."

Old Joseph smiled bitterly: "And I can't think of any foreign objects that can pass through the fuel cavity of a Boeing 777 and cut off its fan blades."

"Oh, then think about it."

Everyone turned around and looked at the person sitting by the window.

Zhuo Huan lowered his eyelids, and his eyes swept over the three-dimensional structure diagram of Boeing 777 on the computer screen.

"Go and contact Rolls-Royce."

He obviously didn't call his name, but Lina knew he was calling her. She smiled and stood up: "Okay. What do you want me to contact them for?"

Zhuohuan raised his head: "Let them provide a Trent 800 engine for experimentation."

Lina pretended to be surprised: "That's it, will they give it?"

As if hearing something funny, Zhuo Huan raised the corners of his lips: "Twenty-three years ago, I suffered a big loss and was wronged by Boeing and NTSB for product quality problems... Do you think they will pay now?"

Lina smiled: "Reid, you are really a bad person."

Zhuo Huan: "Oh, I'm bad, but there are still people who like it." As he spoke, he swept towards Fucheng lightly.

Fu Cheng leaned on the back of the chair, looking at him calmly.

The author has something to say:

Zhuo Anxi: In order to go to Fucheng, I also paid a lot and did a lot of things. I worked very hard.

Fu Chengcheng: ... You have been working hard to make fun of me and satirize me.
