Liang Yuan looked at Wu Zhonghua and shook his head. He decided to light a small fire so that Li Yuanling could know about the future.
Kabakaba Liang Yuan also pretended to be curious and asked, "Grandpa and Mom Wu once told me that turbofan-powered aircraft have greater thrust and fuel economy than turbojet-powered aircraft. Why don’t 99 research turbofan-powered aircraft?"
Wu Zhonghua looked at both of them curiously and said with a wry smile, "This is a long story."
Li Yuanling quickly got up, picked up the teapot, poured two cups of tea and handed it to Wu Zhonghua. He said, "The teacher slowly talked about this Longjing. I haven’t drunk it for many years and I haven’t graduated yet."
Wu Zhonghua took the teacup, blew it to raise the heat and gently took a sip and said, "That is much more precious than this. It was in 62 years that I went to see the Prime Minister after my first rehabilitation. At that time, the Prime Minister told me to work hard and be a pioneer in the aviation industry. When I left, the Prime Minister gave me that bag of tea."
Wu Zhonghua had a look of recollection and said, "The Spey Motive Project was first introduced by the Prime Minister in 1997. After the establishment of diplomatic relations between China and the United States in 72 years, our relations with the West were basically normalized. Therefore, in 1973, Britain said that Batumi promised to transfer Spey Motive Technology to China. Unfortunately, when it was introduced, the central government had a big disagreement and failed to coordinate various decisions. It took several long delays to make decisions. It was not until 75 that we were ready to trial-produce four prototypes. In 79, the teacher was rehabilitated for the second time and went to see Sister Deng, who told
Wu Zhonghua sighed again and went on to say, "Many people know that this project is the last wish of the Prime Minister. After three years, the localization rate of Speer motivation reached 7%. After the initial success, we sent three Chinese-made Speer motivations to Rolls-Royce for testing, and all three of them reached the factory standard of Rolls-Royce. At that time, the project team was preparing to make persistent efforts to further improve the localization level. When the country reached the cancellation document of the localization project of Speer motivation, the whole project team was dissolved."
"When we signed the technology import agreement, we promised to purchase five complete sets of Spee motive machines in batches, and we will buy five sets of localization projects of Spee motive components in the future. Once this promise is cancelled, it will also be yellow. Because we unilaterally tore up the contract and finally compensated Rolls-Royce for the localization project of 20,000 pounds, it just happened that the navy wanted to introduce teachers from type 42 destroyer, England, and continued to study Spee core machines, which conveniently promoted the project of Spee reform."
"In turbojet 13, it was 99 companies that made power improvements for J-13 and J-7, and the horse project can be said that turbojet 13 was developed by 91 companies for 99 companies. Our motivation research is attached to the main engine plant for producing aircraft. The motivation research, capital flow, procurement, goods and so on have to be arranged by the main engine plant, which is a small project in the whole aircraft project."
Shengjing Aircraft Factory, the largest aircraft manufacturing enterprise in China, mainly develops and produces aircraft for the army. At present, the fifth, sixth and seventh fighters of the army are all developed by Shengfei first. At present, the new fighters of the sixth national equipment were also developed a few years before Shengfei, so if 91 Shengfei has a project to support 91, 99 will have a project.
"Grandpa Wu, which plane is your motivation for developing Spey?" Liang Yuan pretended not to know anything, so he asked.
"Spee’s motivation is that the West Flying Company develops a general JH-7 for the navy and the army. (Note 2) The power supporting project is that the JH-7 project is very difficult. After the JH-7 project was formally established in 79, it fell into a quarrel. The JH-7 design took two pilots and the navy hoped that the cockpit would adopt a parallel layout, while the cockpit would adopt a series layout. This was a full quarrel for three years." Wu Zhonghua held out three fingers and gestured.
"It wasn’t until after the naval battle in Amashima that the project team decided to adopt the serial layout suggested by the navy, but since then, the army has been careless about the JH-7."
Liang Yuanyi listened to his heart and said, Isn’t this the terrapin f35? It’s no wonder that the terrapin f35 fighter plane has never been seen before Tonghua. Otherwise, it wouldn’t have jumped into Tonghua pit. At least the terrapin is fighting between the sea and the army. It’s a scuffle between the six teams of the sea and the navy. It’s no wonder that the terrapin f35 has not been formally equipped with troops for sixteen or seven years.
"The army is very dissatisfied with the serial layout of the J-H-7 cockpit, and thinks that this layout can’t meet the military tactical requirements. Finally, the development of J-H-7 has gone through the naval budget, and the whole project team has only been allocated 400 million yuan, and 400 million yuan is not enough to engage in the aircraft. Therefore, there are five original Spey motor libraries, and the localization Spey project has been cancelled."
Liang Yuan listened to Wu Zhonghua and thought that Wu was still a pure scientist. He believed whatever he said.
Shengfei 91, the leader of China’s aircraft manufacturing industry, has always regarded the production of military aircraft as its own private residence. When Shengfei and Xifei competed for JH-7 and failed, it was not pleasing to the eye to see Xifei. That was because a certain army had been entangled with Shengfei for 30 or 40 years since the founding of the People’s Republic of China. Where is a close saying? The army was disappointed with JH-7 and then gave up JH-7. It would be strange if Shengfei had not fanned the flames.
In the past, the giant cow got the J-10 project in the crevice of Chengdu Aircraft Factory in 1911. After that, the aviation department was also suppressed and couldn’t lift its head. At that time, the slogan of the army and Shengfei was to want 27 to want more. 27 Yu Ji completed all flight tests, and there was no chance to equip the troops until 36. At that time, Tian Yuqiang, a test pilot of J-10, visited 911. At that time, Tian Yuqiang bss fell in love with J-10 at first sight. After hearing that No one wanted J-10
A very interesting thing happened when J-11 flew into the sky and then matched J-10 and Su-27. After taking over the Taihang Motor Development Project, 99 took over the core machine temperature of the original Taihang Motor developed by China Gas Turbine Institute, which caused the difficulty in matching the fan with the original design core machine. The temperature increased by 62 degrees, which was equivalent to reducing the material strength performance to one-third of the original, and even passed the physical limit of the material. This failure to follow the scientific laws eventually led to many problems after the Taihang Motor was finalized, and the production type was delayed.
What 99 Institute did was also because China’s Air China industrial motivation industry had no position, and all the forces were taken away by the main engine plant. The motivation research unit could look at the aircraft development plan and squeeze in desperately to get a chance to develop scientific research, which means that it is necessary to revise the plan from the other side’s requirements, rather than making the motivation plan according to the current situation of the technology exhibition and its actual technical level.
Is the 62-degree temperature of the forced high-core machine inspired by 91? Or was it inspired by 911?
Of course, 99 is not a good bird, or it may be that the high temperature on its own initiative means that it doesn’t have the basis of turbine research to eat old. After all, terrapin is the most particular about following up. This kind of bad debt is true, and it is not something that ordinary people can understand.
Wu Zhonghua looked at it with rapt attention. Li Yuanling and Liang Yuan sighed deeply and said, "In the teacher’s mind, it is secondary to change Spey’s motive to naval power or to systematize the motive. The most important thing is to understand Spey’s motive core machine technology through the gas turbine."
"If we can thoroughly understand the core engine technology, we can increase or decrease the number of high-pressure and low-pressure compressors by enlarging the bypass ratio of the engine for a short time in the future. Unfortunately, there are also problems in the navy at present, and the teacher has been entrusted by the negative prime minister after all these years."
Note 1: The major overhaul period of the motive is the same as the major overhaul of the automobile for 10,000 kilometers. The major overhaul needs to unload the whole motive plane and replace it with N new parts, and then the major overhaul interval becomes the second half. In terms of the difficulty of loading and unloading the motive of the terrapin, it takes about one hour to change a motive, but the motive needs to be overhauled after 75 hours. This kind of junk is admirable for the terrapin army to defend the country.
Note 2 J-H 7 is the famous flying leopard fighter of HNA.

Chapter 21 Jumping the Pit and Ten Million
Liang Yuan spent a day in 99 Institute, listening to Wu Zhonghua’s remarks, which made people feel sad about the past. Later, Wu Zhonghua arranged the ignition operation of the gas turbine set the day after tomorrow and didn’t go home.
After dinner in 99 staff canteens, Li Yuanling took Liang Yuan to enjoy the night factory for a while, and then the two slowly strolled to the 99 family community.
In June, Shengjing has a taste of summer. Many employees in 99 factory wear really good shirts. After dinner, the people in the factory area and the family community are constantly busy. Liang Yuan and Li Yuanling are talking about the appearance of Shengjing with their mothers, but they are turning to various thoughts.
Two tons of fuel oil prepared by the 99 Institute today is enough for the unit to burn for three or four days, and one yuan/kg of fuel oil will cost 60,000 to 70,000 yuan a day. Moreover, the unit will have to undergo a five-hour long-term test run and a three-hour full-power life test in the future, and it will cost more than 10 million yuan to run out of fuel oil. No wonder the country can do the aerodynamic test and 15-hour test run, even if it is a gas turbine.
Rebirth Liang Yuan to Li Yuanling’s participation in the Spey project team has always been an attitude of procrastination until then. The eye can’t drag it out. Within a week, the ignition data of Spey’s modified unit will come out, even if its wings are hard to estimate, it can’t be fanned here. Although I didn’t know the specific value of unit operation in my previous life, this data should not be optimistic after listening to Wu’s research on the unit today. The Masy’s modified project team will face the problems of divestment of the 423 plant and so on.
Do you want to jump to Liang Yuan in this pit? I wonder if I didn’t know that Wu Zhonghua had the technology of Si Bei **a1 gas turbine set. Liang Yuan must have chosen to give up cleanly, but now the drawing is scratching Liang Yuanxin like a kitten. But in the future, the two best naval powers on this planet are that nb is better than 125 gas turbine trains, and the efficiency is also defeated by Rolls-Royce. There is still a 3% gap with Rolls-Royce. After all, Americans have deep pockets and fuel-efficient design, and there is no British people’s heart.
Besides, there is no more profitable business in this world than arms and drugs. At present, the price of a set of Spey s_a1 gas turbine in Rolls-Royce is about 260,000 pounds, which is converted into terrapin currency, which is 310,000 pounds. It will definitely be further compressed after mass production in the future, and the after-sales maintenance of high-tech equipment such as gas turbines is absolutely inseparable from the manufacturers. Generally speaking, the service life of the whole set of equipment is at least half to half, and the maintenance of black-hearted guys like Toyo Ghost can reach the service life of 7%-.
Six times less profiteering. Liang Yuan smacked his lips and thought it was enough to go back to the guillotine twice. It is Liang Yuan’s favorite thing to make a lot of money and bring patriotic things like this, but it is a bit difficult
After much reasoning, Liang Yuan decided to set the tone of the old lady first and see what can be drilled.
The place where cream popsicles are sold by Liangyuan roadside pulls Li Yuanling and says, "Mom, it’s so hot outside today. Let’s eat some popsicles here and go back."
Li Yuanling said with a smile, "Even if you go back now, you won’t make up your lessons today. You still know the truth of combining work and rest."
Liang Yuan hey hey smile is no small mind was caught embarrassing.
Liang Yuan and Li Yuanling took popsicles and sat in a cement flower pond. Liang Yuanxian and Li Yuanling talked nonsense about their motives before saying, "Mom, if the navy doesn’t want 99 units this time, will mom lose her job?"
Li Yuanling looked at Liang Yuan and said, "Isn’t there a little millionaire at home? Why do you want to be distracted with your mother now?"
Liang Yuan rolled his eyes at Li Yuanling Nai, thinking about when it will grow up.
Li Yuanling giggled at Liang Yuan’s interesting appearance and said, "Xiaoyuan has grown up and knows his mother."
Reaching out and pinching Liang Yuan’s face, Li Yuanling said seriously, "It’s a little risky to choose a real gas turbine project and join forces with the navy. You have done fan adjustment in the 257 factory, so you should know something about the 257 factory?"
Liang Yuanli nodded his head and made a curious face. Li Yuanling continued, "The current economic situation of the army is difficult to protect itself. Many things are hard-working, and there are many requirements for military procurement. It seems that it is a good thing for my mother to be dumped by the navy."
Li Yuanling paused for a moment, as if to sort out her thoughts, and then said, "Mom won’t think about merging with the army after taking over. You’ll know how poor the army is. Xiaoyuan also walked with her mother all day today. Guess what else the gas turbine can do besides being a motive?"
“！” Liang Yuan blurted out.
Li Yuanling looked at Liang Yuanxiao, stretched out his hand and touched Liang Yuantou and said, "Xiaoyuan and his mother want to go together. Tell me what you think."
Liang Yuan said with a smile, "I’ve been to the 257 factory for so many times, and I’ve listened to it for several times. Besides, I also studied the increase when I got the fan. Of course, I know that the gas turbine can be used."
"Don’t worry about mom’s unemployment this time, right?" Liang Yuan nodded his head and said that it would be much bigger for me to pull this thing into the people’s field and jump into the pit myself.
I felt that there was a bright future ahead. Liang Yuan was relaxed and ate five popsicles in a row before returning to 99 family quarters with Li Yuanling.
Just entering the room on the fourth floor, Liao Min said to Liang Yuan, "Xiaoyuan, your brother-in-law called you today. Maybe it’s for you to come back to one." Then he handed a piece of paper to come over.
Liang Yuan took the note and asked, "When will grandma and brother-in-law Liao come to talk?"
"In the afternoon, you and Xiaoling came to talk soon after they left."
Liang Yuan looked at the wall clock just after seven o’clock. This point should be returned to the office and dialed according to the paper number.
After the third tone, Liang Haiping’s rich voice entered his ears. "Hello, who is this?"
"Brother-in-law, I am Xiaoyuan. What is it?" Ghost in my heart Liang Yuan involuntarily lowered his voice and looked at the other side of the sand and Liao Min’s homely Li Yuanling.
Liang Hai Pingyin also lowered his voice and said, "Xiaoyuan, no matter what reason you have, you’d better come back recently. Factory director Wang has come to see you several times over there."
"What’s wrong with the brother-in-law fan?"
"No, yesterday, the factory director Wang already called the profit in May." Liang Hai Pingyin was slightly out of shape.
"Ha ha brother-in-law can relax this time."
"Xiaoyuan" Liang Hai Pingyin is a little lower. "Ten million! Factory 257 fully called. Ten million brother-in-law slept for an hour last night. You’d better come back once. I can’t tell you anything."
Suddenly slipped to the mouth "10 million?" Three words swallowed back Liang Yuan took a deep breath and was glad to think that it was okay and didn’t embarrass the crossing people.
"Good 66 times straight brother-in-law, where are you working now?"
"I’m in the overhaul factory. You can come directly to the overhaul factory for lunch at noon."
"Well" put words Liang Yuan struggled to think about what reason to sneak back?
Thank you for your support. Your support is our greatest motivation.
