Return to 2000: Captain of the Great Powers
Chapter 367 Pratt & Whitney's Sinister Intentions!
Chapter 367 Pratt & Whitney's Sinister Intentions!
"Crazy, what do you mean?" Xu Cang didn't understand the meaning of these words for a while, or to be precise, he expressed difficulty in accepting such sudden information.
"Literally." Ma Cheng also seemed quite strange: "He has been arranged to live in our employee community since he came back. He is not high enough, but he was given the best accommodation, which seems to be a small villa. Some time ago It's all normal, but the day before yesterday, the residents of the villa next door reported that Park Dek-gyu's house was very noisy, and there were constant movements of throwing things. Then I asked the company's service office in the community to check the situation, and then I knew That's it."
Xu Cang knew the employee community of Muhua Airlines in Yangcheng. When Spring and Summer Airlines planned to fly the plane at Yangcheng Airport, he expected the housing situation of the foreign personnel in Yangcheng. He once considered the employees who lived in Muhua Airlines. Xu Cang even visited the community.
However, later on, because Muhua Airlines didn't have many rooms left, the matter was dropped.
Xu Cang, the small villa mentioned by Ma Cheng, has an impression. The distance between the two villas is not too far, but there is also a small road and a green space separating them. The residents next door can hear the movement, and the volume is indeed enough. big.
"Pu Degui has a very bad temper. When our people went into his place, he smashed most of the things inside. These things were all bought by the company." Ma Cheng said: "Actually. , if it was just smashing things, the problem wasn't too big, but he didn't know what medicine he had taken, so he beat up the employee at the service office who checked the situation, his head was broken, and finally the employee directly called the police .”
"Do something?" Xu Cang was stunned: "Is his temper too violent?"
"That's not the case." Ma Cheng said hastily: "Even if he had a bad temper before, he wouldn't have made a move."
Xu Cang snorted: "That's not necessarily the case, some atmospheres in the aviation industry are not very good."
These words directly choked Ma Cheng, and after a while, Ma Cheng felt a little helpless: "I know that some pilots and instructors will beat and scold the co-pilot during the flight, but getting started is a different concept from seeing blood. Well, it’s easy to have a criminal record, the pilot has a political trial, how can he have a criminal record?”
The profession of pilot is not completely commercialized. Once you have a record of criminal cases, you basically say goodbye to this profession.
Anyway, judging from his previous performance, Park Deok-gyu doesn't look like he is going to give up his career at all, which is very strange.
"I've had a drink."
"No, that guy is allergic to alcohol." Ma Cheng's tone was full of doubts: "Let me tell you, that guy hit hard. The employee who went in to check the situation seemed to have been beaten to concussion. It's not a trivial matter. The police behind I took him away, and checked to see if the guy was smoking that, but there was nothing. Then he was sent to the psychiatry department, and the doctor said that he had a relatively serious paranoid disorder, and he might have been stimulated by something."
Xu Cang snorted: "What's wrong with this sudden spirit, you can't be the one who did it?"
Ma Cheng is very complicated, but Xu Cang is sure of one thing, that is, his mind is as small as the tip of a needle.
Ma Cheng and Park Dek-gyu had conflicts before, and now that Ma Cheng has become the chairman, although he has not covered the sky with one hand, it is not difficult to lay hands on a Park Dek-gyu who has gone and returned.
This made Ma Cheng a little unhappy: "I'm being cautious now. If I want to deal with him, I'll wait for my position to be stabilized. I can do things that make big mistakes. However, I think he's not happy with this guy." , although I don't know the reason, but with his mental problems, I'm afraid I don't have to see him in the company anymore."
If you have mental problems, you will definitely not be able to fly.However, in the aviation safety manual, there are some strict regulations on whether a go-around is allowed after recovery from mental illness.However, this is a common international standard. To be on the safe side in China, people like Park Deok-gyu who have had a history of severe mental illness basically bid farewell to flying. He signed it.
"There's really no guesswork at all. A person can go crazy alone."
"It's not that there is nothing." Ma Cheng's tone changed, becoming mysterious, completely inconsistent with Xu Cang's impression of him in the past: "There is a saying, that is. A voice message, tsk tsk tsk, at that time he happened to be reading the information about the China Airlines crash, and then the voice message was a little scary, maybe he was scared crazy, right?"
Regarding this, Xu Cang sneered: "You are also an executive of a state-owned enterprise. Can you be more materialistic when you talk about these gods and ghosts?"
"I'll send that voice message to you." Ma Cheng was unhappy on the spot: "The police station found out that this voice message came from the number of one of the victims of the China Airlines crash. Who can tell you clearly about this stuff."
"What are you kidding?" Xu Cang snorted, "There are still survivors? There are still survivors in the air crash that disintegrated in mid-air?"
Ma Cheng was obviously also confused: "How do I know, you listen to it yourself, anyway, this thing is very evil. I will send it now, you keep it."
After finishing speaking, Ma Cheng hung up the phone directly.Not long after, Xu Cang's mobile phone notified that he had received a multimedia message, and the attachment was an audio file.
Xu Cang opened it. This audio file is very short, less than 1 minute.
He turned up the volume of the loudspeaker to the maximum, however, what just came out was the sobbing of a young man, and the sound of waves hitting the rocks could be heard faintly.
"What?" Xu Cang asked himself, and he wasn't too timid. This was a man crying in the background sound, and the picture was really weird.
Then, the content in the audio changed suddenly, and the man's painful and desperate cry sounded: "Don't... I don't want to die, don't die here."
Before, Xu Cang felt very uncomfortable when he heard a man crying in a low voice, but when he heard this, his hairs really stood on end.He finally knew what Ma Cheng meant by Xiehu.
Now Xu Cang is still in broad daylight, surrounded by people. In such an environment, Xu Cang feels terrified. If he listens alone at night in some claustrophobic environment, will he be scared out of his wits? (China Airlines recording is a very famous event, but I don’t know how to explain it later. I don’t know if anyone knows?)
However, just when Xu Cang was about to listen further, he suddenly felt something, raised his head subconsciously, and suddenly saw a man in his thirties and 40s standing not far in front of him, staring straight at him .
He was already nervous because of the audio content, but when he suddenly saw someone staring at him, he was really taken aback, and instinctively flinched.
This man was wearing a pilot uniform, with a Spring Airlines boarding pass, four stripes, and as soon as he saw Xu Cang noticed him, he immediately walked over: "Mr. Xu."
"Don't keep quiet if you have something to do, it will scare people to death." Xu Cang temporarily paused the audio, and took back the phone: "What's wrong?"
The captain looked a little embarrassed and nervous: "Mr. Xu, there's something wrong. Isn't our flight delayed? The dispatcher calculated the duty period, and the co-pilot's duty period is about to expire, so he can't fly. .”
"Timed out?" Xu Cang raised his eyebrows: "You didn't time out, but the co-pilot did?"
"That's right, the co-pilot overtimed. Before he flew two sections, he flew another section. I only had these two sections today, so he was overtimed, but I didn't. Now this matter is... no one can be found, the dispatcher said If people are transferred from Erhai Lake or Jianchuan, the next flight will be two hours later, plus the empty time, it is estimated that there will be a delay of more than five hours."
Regarding this point, the scheduling is really not making excuses, but really can't find anyone.
Hanking has no sub-bases and no overnight hotels. This situation is difficult to deal with, and we can only transfer people from the headquarters.
In 2000, there were not too many flights. If it is more than ten or twenty years later, the flight between Jianchuan and Hanjing is estimated to be half an hour, and there will be one flight every hour, and there is absolutely no need for such a long interval.
Xu Cang understood the meaning of the captain and dispatcher: "You came here to let me fly back?"
"Yes, Mr. Xu, have you brought your three certificates?" The captain rubbed his hands with a very respectful attitude.
"I did." Xu Cang scratched his head, looked down at his clothes, "However, my clothes"
It is his personal habit for Xu Cang to carry his ID with him, anyway, the ID does not take up much space, but he will not even carry the pilot's uniform with him, this is a bit outrageous.
"It's okay, it's okay." The captain hurriedly said, "It doesn't matter."
Xu Cang frowned: "Why doesn't this matter? If you are found out, you will be punished."
"That's much smaller than the loss caused by a five-hour delay." The captain seemed to have thought out his excuse before he came: "It's fine if you have the three certificates, and the clothing is relatively not a matter of principle. The company said it doesn't matter."
"You." Xu Cang was speechless. Why did he feel that the operation and control department of Spring Airlines and Shandong Airlines have become more and more similar.
It is true that the incomplete documents are a matter of principle, and if they are found out, it will be fatal.Relatively speaking, the impact of non-compliant clothing is much lower, at least there will be no joint punishment, and at most it will be fined and criticized and educated.
The capacity of Spring Airlines is very tight, so the planes are very full.If the plane is delayed for more than five hours in Hanjing, then the following flights will also be delayed, and it will not be able to be adjusted at all, and the loss will be huge.
This is called the lesser of two evils.
Xu Cang looked at his sneakers: "I have never stepped on the rudder with my sneakers."
Hearing Xu Cang's tone, the captain seemed to agree, and secretly heaved a sigh of relief: "You can try it later."
Now that the matter has come to this point, Xu Cang can only accept it, but he made a statement: "If the bureau wants to punish me, the company must pay me."
The corner of the captain's mouth twitched, the whole Spring and Summer Airlines is yours, don't you just use your left hand instead of your right hand?
Xu Cang could also see that his joke was a bit cold, and patted the captain on the shoulder: "Go in, call the operation control to change the mission statement, and ask the agent to send the new mission statement."
If the crew members are changed, a new mission statement is required, and even the release information must be changed.Because there are crew members' names in the release form, a second release must be performed.Spring and Summer Airlines does not have a branch base in Hanjing, but there is an agent, and the operation control can fax the new mission statement, and then the agent will send it over by hand.
The captain promised again and again, just like a co-pilot.
In this way, Xu Cang will definitely not be able to enter with the passengers.He took out the boarding pass from the luggage, and boarded the plane together with the captain from the boarding gate.However, when the boarding gate staff checked Xu Cang's boarding pass, out of the corner of his eye, Xu Cang saw an old figure standing on the edge of the seat not far away, and he always felt that this figure was somewhat familiar.
"Okay." The ground personnel at the boarding gate quickly checked Xu Cang's ID. These words interrupted Xu Cang's thoughts, and he followed the captain directly into the corridor bridge without thinking too much.
When the two walked in, the captain wanted to compliment him: "Mr. Xu has worked hard today."
"I don't really want to take this kind of catch."
"Why?" The captain was a little surprised: "This plane doesn't have a first-class cabin, and the passenger seats are not as comfortable as the seats in the cockpit. Anyway, it takes more than three hours to sit, so it's better to fly back and save experience time."
Xu Cang said with a smile: "Well, there is a saying that picking someone else's Ban Fei is easy to cause accidents, and I don't know if it's true or not. Have you heard this saying?"
Xu Cang's statement is not his current cognition, but before his rebirth. He doesn't know if there is such a statement in this era.
"This." The captain laughed a few times: "I've never heard of it."
"That's my nonsense." Xu Cang laughed loudly, and walked towards the cabin with the captain.
On the sidelines of the Pratt & Whitney Power plant test site, President Clark Lorenz is squinting at the PW8000 test machine fixed on a bracket not far away. Beside him, the secretary Carl Horstein looks serious and seems worried. .
As the PW8000 testing machine started to operate, rumbling sounds came over, and the sound waves came one after another, as if even the heart, liver, spleen, lungs and kidneys were vibrating along with it.
However, fortunately, the two of them were far enough apart. Although there was some discomfort, it didn't have much impact.
Suddenly, when the running sound reached its maximum, it was almost the time when the PW8000 was outputting the maximum power. Even from a long distance, Clark Lorenz could feel the air waves blowing towards his face.
"What a strong motivation." Clark Lorenz sighed.As the head of Pratt & Whitney Power, he is not the kind of manager who can only give orders in the office, but really understands technology. He can roughly feel the power limit of PW8000 just by the air waves formed.
Secretary Carl Horstein said with a smile: "Different speed configuration can optimize the performance of the engine"
However, as he spoke, the smile on Carl Horstein's face softened a bit: "However, after about 2 minutes of maximum power output, some small, unexpected problems will appear on the low-voltage fans."
"what is the problem?"
"That is. According to the feedback from the technical department, it may be that the engine's control system cannot accurately control the differentiated rotational speed, making it prone to backflow of airflow at maximum power output."
"Backflow!?" Clark Lorenz was taken aback, and immediately scolded: "Isn't that just a surge?"
There are many reasons for engine surge, but the most common is the backflow of airflow, which then blocks the intake passage, causing engine surge.
The low-pressure fan and high-pressure turbofan of the PW8000 engine are not connected in series by a shaft, but a computer-controlled planetary gear variable device is used to actively adjust the speed of the low-pressure fan.In this way, the performance of the engine can be greatly improved.
However, it may be because the control system on the low-pressure fan is not perfect, and the air intake of the PW8000 has not been perfect, which leads to the silting of the air flow at the high-pressure turbine under certain conditions, which makes the surge occur. .
Once the surge occurs, it is easy to pose a huge challenge to the structural strength of the engine.
In order to deal with the structural damage caused by surge, Pratt & Whitney adopted enhanced dual-rotor technology.In layman's terms, that is, as long as my engine structure is strong enough, I don't care if the engine is out of breath.
But the problem is that although the shifting technology leads to the occurrence of surge, it actually enhances the engine performance.As the performance of the engine increases, the greater the damage caused by surge, and the enhanced dual-rotor technology can't even withstand this high-intensity surge.
Karl Horstein explained the engineering department's concerns a little to Clark Lorenz.
Recently, Clark Lorenz had been devoting himself to the PW8000, and when he heard that there was such a big problem, he became angry.
However, Clark Lorenz had a relatively good temper, and he didn't get angry immediately: "How can the surge be the strongest?"
"that is."
Karl Horstein was just about to say, when he heard a bang in the distance, the air inlet and tail nozzle of the PW8000 test machine fixed on the bracket ejected flames at the same time, and then the originally smooth running sound stopped. The panting sound of thick phlegm was the same, harsh and dangerous.
Seeing this, the technicians next to the test site rushed to shut down the engine urgently, and the scene was chaotic.
"Basically that's it." Carl Horstein sighed.
Clark Lorenz covered his forehead and cursed: "Damn it!"
"Boss, in this situation, we can't even get a flight test permit from the FAA, let alone let Xu Cang come over for a test flight."
Clark Lorenz put one hand on his hip, his face was full of anxiety: "If we continue to delay like this, we will be left far behind by the Trent 1000. The more it gets to this time, the more we need Xu Cang to come over Conduct flight tests."

Karl Horstein was just about to say, when he heard a bang in the distance, the air inlet and tail nozzle of the PW8000 test machine fixed on the bracket ejected flames at the same time, and then the originally smooth running sound stopped. The panting sound of thick phlegm was the same, harsh and dangerous.
Seeing this, the technicians next to the test site rushed to shut down the engine urgently, and the scene was chaotic.
"Basically that's it." Carl Horstein sighed.
Clark Lorenz covered his forehead and cursed: "Damn it!"
"Boss, in this situation, we can't even get a flight test permit from the FAA, let alone let Xu Cang come over for a test flight."
Clark Lorenz put one hand on his hip, his face was full of anxiety: "If we continue to delay like this, we will be left far behind by the Trent 1000. The more it gets to this time, the more we need Xu Cang to come over Conduct flight tests."
