Chapter 720: The Doctor Talks About Engines
Wuyang said: "No matter what the price, we are going to do it, and if I have the opportunity in the future, I will report to the senior management of the Military Commission, and if they agree, the hero will notify the shipyard to start construction after returning." โ
Xie Daxia said: "Wuyang, we still have a lot of technology that we haven't mastered, and we may need a lot of money to buy it, and we must mobilize the intelligence network of my sister-in-law, you go back and talk to them." โ
"Okay, that's fine. Before you leave the aerotropolis, you must arrange competent personnel to study the UFO data transported this time, and strive to produce results. โ
Xie Daxia said: "I'm afraid this is difficult, right? โ
"The Third Reich succeeded decades ago, and we are basically standing on their shoulders, and what is missing is only part of the information, which is much better than starting from scratch, right? What's more, now that we have nuclear power, we have our own metal materials, and we are willing to invest money, there is no difficulty that cannot be overcome. โ
"Well, you can't set a deadline for them to recruit talents while researching, and they will definitely be successful. From the moment it goes to the sky, there is a possibility that it will fall, and nuclear power may produce nuclear pollution, which will be a disaster for mankind, and we should not consider using it. โ
"Let you arrange, you will be in charge, and in the future, you will go to the marine company, and you can also manage this matter." Still, I would like to advocate arranging for someone to study the use of nuclear power in aircraft. We can enclose the nuclear reactor in a high-temperature, high-pressure container. Hero, I'm going to leave my words here today, and we're not going to do it. There are still people in the world who will do it. We'll be able to see it in our lifetime. โ
"Good. I'll arrange for someone to do it. Anyway, there is a phone and a plane, even if I went to the marine company, it was still very convenient. However, we can't get nuclear materials, so we can only study how it works first. โ
"Hero, the small plane we bought is too difficult to sit on, and it encounters a slightly larger air current. It's so bumpy, I don't dare to sit down, is it also our company itself produced a few planes? โ
"As long as it is a small aircraft, there is this problem, to overcome it must be built bigger, simply we produce a regional aircraft, with 60 to 80 seats, we use it ourselves, and it can also be used as a short-haul route for airlines, even if it is a trunk line. In the case of insufficient passengers, this type of aircraft can also be used. It can save a lot of fuel, so maybe that's a way forward. โ
Wuyang smiled: "I think you still don't want to go to the marine company, you still have a lot of unfinished business here." โ
"you, this hero is still young, and his body is great."
Back at the hotel, Wuyang said, "Hero, did you call Boss Pei and his wife to eat together?" โ
"Uncle Pei is not at home, he went to the south to prepare for the air show, call Dean He, I'll call." Wuyang, do you call the two successors as well? โ
"Okay, you two will call Mrs. Ru here too, they have a table for women, and we have a table."
Fang Yiqing said: "Secretary, it's not that we don't want to introduce them to you, it's that we can't let them know about you." I never talk about these things at home, women, parents are short, and it is inevitable that people will know. โ
Wuyang said: "If you don't call it, don't call it, it's really difficult for your heart." Hero, what about your wife Yang Xi and those such ladies? โ
The hero said while dialing: "Yang Xi is at home, I'll call a few of them here, anyway, they all know about you." You rest in the box for a while, and I'll pick you up. โ
Wuyang said: "I'll pick it up, I haven't seen it for a few months." โ
So I called He's mother, "Mom, I'm in the aviation city, can you have a meal?" โ
He Hongmei said: "Wuyang, when did you arrive?" โ
"I just arrived in the afternoon, I'll pick you up, what villa do you live in?"
"I'm still in the hospital, you don't have to come to pick it up, I'll let my daughter drive."
"Your daughter?"
"Yes, goddaughter. Where are you? โ
"I'm in the Mingyue Lake box of the hotel, then I'll wait for you here."
"Okay, I've been to the Mingyue Lake box, and I'll be there soon."
After hanging up, Wuyang called Haini and Wu Zhiya again. "Hero, the box is so big, there will be no separate table, everyone will eat together."
"Okay, let's just be careful when we speak."
After a while, Heinie and the others came down, and just as they sat down, two people in their 30s also came. Xie Daxia introduced them, the tall one is Bian Jingwei, who is studying economic management, and the middle man who wears glasses is Shu Linlin, who is a doctor of engine.
Bian Jingwei said: "Boss, we have heard of you since we entered the company, but it is not easy to meet you." โ
Wuyang said: "I am usually very busy at work, and the management of the aviation city is also quite in place, so I don't need to be careful, so I basically didn't come." โ
Shu Forest said: "Boss, I didn't expect you to be a young man, I thought that you must have worked hard for decades for such a big foundation." โ
Wuyang said: "I have only been working hard for more than 10 years, but with the struggle of Boss Xie and my colleagues, it is an astronomical amount." Dr. Shu, how many years have you been with the company? โ
"It's been 5 years, but you've been to Rawls again? Royce has been a visiting scholar for two years, and the actual work is three years. โ
Xie Daxia said: "Wuyang, Dr. Shu's doctoral research was completed at General Electric, and after joining our company, we sent him to visit Wรจn scholars, and the two companies he went to are the world's top aero engine manufacturers." โ
Wuyang said, "Dr. Shu, go to them and learn their techniques?" โ
Shu Linlin said with a smile: "Where can I say that I have learned, it's just a little fur." People keep the key technologies strictly secret, and there are a lot of theoretical things to show me, but the actual things are simply before leaving, let me take a look at them. โ
"Can I come back and use it for real work?"
"I'm just studying engines, and I don't know anything about them. There is also quite a bit of understanding. Take a closer look. Basically, it can be used in practice. In addition, our company has a large number of technicians, perfect production equipment, and engines purchased from General Electric and Rolls-Royce as samples, it is not difficult to produce them. โ
Xie Daxia said: "Wuyang, tonight or tomorrow, let's go to the engine factory to have a look, now we are ready to eat and drink." โ
"Good. Let's go to see at night, tomorrow there may be something at home, and we will leave. Hero, then I won't drink with you and Lao Fang. โ
"Hero, forget it for the two of us, the secretary is a person in the officialdom and can't help himself, so let's not force him."
Xie Daxia said: "Okay, let's get together again for the New Year." โ
Just as He Hongmei came in, followed by a beautiful girl, and several men looked straight in the eyes. The girl was blushing by everyone. Wuyang introduced a few people present, and He Hongmei said with a smile: "This is my daughter He Wei." Pretty enough, right? โ
Several people nodded and smiled, and He Hongmei said: "He Wei is an internist who graduated with a doctorate this year and has been interning in the hospital for several years. Xiaowei, this is Wuyang, don't you want to know each other for a long time, you can have a good chat. As he spoke, he asked He Wei to sit beside Wuyang.
On the left of the afternoon sun is Hai Ni, on the right is He Wei, in front of Bian Jingwei and Shu Linlin, that is to say, some words that everyone can listen to. Slowly, Fang Yiqing and Xie Daxia became lively while drinking, and Bian Jingwei also joined the ranks of drinking, so no one cared about them.
"Brother-in-law, are these women all your lovers?"
"Yes. But in my family, all of them are equal, they are all wives, and there is no such thing as a lover. โ
He Wei said, "Do you think I am qualified to join their team?" โ
Wuyang shook his head, "He Wei, do you know, you are choosing an abnormal life, not to mention that you have no name, you are studying medicine, I will be blunt, even if you want to live a normal married life, it is impossible." โ
"Normal life, that is, a plain glass of boiled water, going to work every day, housekeeping children after work, as well as trivial chores such as firewood, rice, oil and salt, when I am old, I realize that my life is not worth it. If I can live with you, Sister Pei Lei is a role model, I think this kind of life is what I want. Married life is just a part of life, and if you are so good at kung fu, you will definitely not let me down. โ
"You know everything?"
He Wei smiled: "Of course I know, Pei Lei is my sister, she won't tell me anything." As the saying goes, my sister-in-law is good-looking, my brother-in-law is half as good, and I am 28 years old, just waiting for you. โ
"Does Mother He know your thoughts?"
"Don't talk about my mother, the first time she saw me, she said that there was only one person who was worthy of me as a husband, and later I found out that this person was you."
"Okay, in that case, you're mine, and you'll go home with me tomorrow."
He Wei said: "Why do you want tomorrow? I'll stay at the hotel tonight, and I'll go home with you tomorrow. โ
Wuyang smiled: "You are also active enough." โ
He Wei smiled and said: "After this village, there will be no such shop, of course I have to take the initiative." โ
"Admire your courage, eat, and go upstairs with your sisters when you're full."
After eating, the three of them were still drinking, and Wuyang said, "Dr. Bian, you have a good amount of alcohol." โ
"Where, compared to the boss, it is a heaven and an underground. Boss, when you are full, go first, so as not to let you see my drunken state and leave a bad impression on you. โ
"It's all right, he who drinks, who doesn't get drunk? As long as I don't drink and make trouble, I can tolerate it. โ
"Don't worry, I'm drunk, I'm sleepy, and I can't open my eyelids."
"That's fine. Chairman Xie recommended you to take over, are you ready? โ
"I didn't deliberately prepare anything, anyway, I have studied with Xie Dong and Pei Dong over the years, and I have some experience."
"Okay, it's good for you and for the company to be useful."
"Thank you, boss, thank you, Dong."
"Then you drink slowly, let's go first. Dr. Shu, I'm going to your engine factory to see, is anyone working now? โ
"We all work 24 hours a day, seven days a week, and all of us are on rotation." Shu Forest said.
"Mother He, then you can arrange it yourself. Now that you have a successor, you and Dad can go home and rest. It's time to have fun. โ
He Hongmei said: "I can't be idle anyway. The company wants to build hospitals all over the country. There is still a lot to be busy with in the recruitment and deployment of personnel. Leave us alone, let us be free to do whatever we want. โ
When he arrived at the engine factory, Shu Linlin took the first person into the production area. There are five large houses with white walls and blue tiles, and in addition to transplanting tall trees, forklifts and cranes are parked between the houses. There are also a lot of bikes.
"Dr. Shu, what are you doing with so many bicycles?"
"Boss, the bicycle is for the workers to use when they go to work. Each of our workshops is 100 meters wide and 10 kilometers long, and there are no motor vehicles to get around, only these bicycles. โ
"Can such a large workshop be used?"
Shu Linlin said: "There are thousands of parts in the engine, from raw materials to qualified parts, which need to go through many processes, and some parts are used in large quantities. There are more people in the production and the parts are larger. The space occupied is also large, plus there are warehouses for raw materials and finished products, as well as assembly lines and testing lines for engines, these workshops can only be said to be sufficient. โ
"How many people work in the engine production plant?"
"Since the processing and assembly are basically manual operations, and there are no holidays on Saturdays and Sundays, more than 30,000 people are required to carry out normal production. Boss, look, where to go in such a big place? โ
"What are you doing here? Let's go in and have a look. โ
"This is the key part of the engine, the blade production hall of the turbofan. Boss, you can't say it after you read it. โ
Wuyang smiled: "I know this, you can explain it while leading the way." โ
"Good. You see, these are high-grade titanium alloy plates, and each blade of this blade is a single crystal, that is, a molecule, if it is multimolecular, there is a zร i boundary between them, and the structure is not tight, and it is easy to be damaged. โ
"Such a big single crystal?"
"Yes, you see that they are so thin, but they are still three-layered, just like sandwiches, they are filled with inert gas, and when exposed to heat, they do not expand too much, so that the blades do not deform. There are also many small holes in the blades, which are done to reduce the weight of the blades and increase the heat dissipation effect. As long as the blades work, they are in a high temperature state of 1700 degrees, and without good heat dissipation, they are easy to burn. โ
"This blade is expensive, isn't it?" Wuyang asked.
"Yes, the price of one piece is equivalent to an ordinary car, an engine, and 96 blades, blades and brackets are worth $750,000. Boss, let's put it this way, all the parts, there is no less than 12,000 yuan, including the screw nut. But the money is well spent, the blades can increase the thrust of the engine by 75%, and each blade produces the same power as a Formula 1 car, which is the key to why turbofan engines are superior to propeller engines. โ
"In the past, we bought foreign CNC machine tools, just to process blades, right? Now our CNC machine tools, can also complete this job? โ
"Yes, our CNC machine tools are all produced by ourselves, and they can also be sold. The requirements for the blades are very strict, and after they are produced, we have to go through the inspection of the naked eye, computer and X-ray, and there is no flaw before they can be used for installation. โ
Seeing that the workers were hoisting the engine, and the crane was lowered a few millimeters each time, Wuyang said: "So careful." โ
Shu Linlin said: "Yes, there can be no scratching or rubbing, otherwise it must be sent back to the workshop for reprocessing." These hoisted modules are composed of hundreds of parts, if scraped and wiped, they must all be reworked, and the rework is not a module, and the trouble is big. โ
"How long does it take to produce an engine?"
"It takes 20 days from the start of the first module of the engine, to the completion of the assembly of the engine, and then to the flight test center for test runs in various harsh conditions, and thousands of hours."
"What harsh conditions?"
"The low temperature is minus 40 degrees, and water, snow, hail, etc. are added from the air intake."
"Did you have any engine damage during your test drive?"
"To test whether the blades fell into the fan box, we damaged one engine, but otherwise it wasn't."
Wuyang said: "How big is our output? โ
"If we were in normal production, we would be able to produce four engines per week, two each from GE and Rolls-Royce. However, we have no orders now, and the engines produced are all used by ourselves, only input, not input, but I am afraid that it will drag down the company and make the company unable to operate normally. โ
"Is it at full capacity now?"
Shu Linlin said: "Yes, now the company produces about 8 large engines and about 2 small engines every month. โ
"Are small engines also produced here?"
"No, it's produced in a factory next door, but it's also a factory."
"Why is the production of small engines smaller?"
"This kind of engine has no market in the international and domestic markets, needless to say, the domestic has also produced the 'Taihang' engine, which completed the design finalization review and assessment, one year earlier than ours. However, our production is still much cheaper than buying, and it can be delivered in time. โ
"Taihang engine is my country with complete intellectual property rights, right?"
Shu Linlin said: "Yes, we should also be happy for the country, the era without turbofan engines is gone." โ
"Dr. Shu, is there a way to get an order for our turbofan engine?"
"Boss, if these products are now, I'm afraid they can only be used for the production of large aircraft that my company needs. General Electric and Rolls-Royce have established a perfect sales system, their engines are paid by flight time, each engine leaves the factory, its operation is connected to the factory's computer, the factory has maintenance centers in the world's major airports, product support and customer service, can be dealt with in a timely manner, has established a good image among customers. We want to replace it, unless it takes a few years to do it. โ
"In the current context of global economic integration, such an idea is unrealistic, and we can only find another way," Wuyang said. Dr. Shu, you are familiar with the aviation industry, where do you think we can make a difference? โ
"Boss, I haven't thought it through, and my opinions may not be correct, so you have the right to listen to them."
"Well, it's not going to happen overnight anyway."
"One is to make a fuss about our own planes. We have ordered 40 aircraft, and after they are produced, they do not necessarily have to be kept for their own use, but some can be transferred and replaced by aircraft of their own production, which is a way; The second is to open up the freight business, the current domestic air cargo is almost still blank, we can fill this gap; The third is to contact the military and sell transport planes to the Air Force. At present, the price of the C-130J military transport plane in the United States is $175 million, and they are not sold to China, but the Il-76 transport plane used by the Chinese Air Force is imported from Russia. We produce transport aircraft, the performance is better than the above two aircraft, the price is also lower than the C-130J, our cost is about 120 million dollars, if sold to the Air Force, 150 million dollars is enough, only slightly higher than the Il-76. We can also produce super-large strategic transport aircraft like the An-225 according to the needs of the Air Force, or modify them into early warning aircraft and tanker aircraft. โ
Wuyang said: "I may be able to meet people from the military in the future, if we can reach a consensus of intentions, how many transport planes can the company produce each year?" (To be continued......)
