Liang Yuan put words in my ears and wanted to echo Ning Wanjia’s crisp, sweet and greasy coquetry. "You pig head have sneaked away again. I haven’t seen you for more than a week." Liang Yuan is now regretful. There are two beautiful girls who don’t go to Shengjing to review their past lives every day. After Liao Minjue’s good foundation, he greatly accelerated the teaching progress and praised Li Yuanling. Li Yuanling’s foundation for Liang Yuan is too solid. It is high time to come and apply for the exam when he is still in primary school.
Li Yuanling has been numb to this question and said to Liao Min with a wry smile, "Aunt Liao, I want to say that Xiaoyuan has always been stocked. Do you believe it or not?" Liao Min shook his head and said, "Xiaoling, education is the most important thing. You should know that example is far greater than words. It seems that you haven’t lost your knowledge on weekdays. No wonder Lao Wu is happy these days. How is your progress?"
"I’ve studied all the new papers of the teacher in recent years. If I want to become my own thing, it will take a few months. I plan to go to 99 places with my teacher to see the teacher studying the gas turbine. I haven’t seen the prototype for so many days."
Liang Yuanyi’s interest in going to see the gas turbine has risen greatly in previous lives. Where did the ordinary people have the opportunity to see this saying? Kabakaba’s eyes ran to Li Yuanling’s side. Li Yuanling knew his mind when he saw Liang Yuan’s expression. He said with a smile, "It’s bad to have been attached to ten zakat classes. You can go with your mother."
The next day, Liang Yuan excitedly followed Li Yuanling to the famous Shengjing 99, which is located in the northern suburb of Shengjing. It is the design and research center of large and medium-sized aero-engines in China. The cradle of producing large and medium-sized aero-engines in China also made the fans love and hate places enter the main entrance of the factory. Liang Yuan was curious and kept pointing to the surrounding buildings to ask Li Yuanling about her way.
The institute covers a large area and the building density is not high. Many buildings are shaded by thick green trees. Zhong Liangyuan followed Li Yuanling along the tree-lined road in the factory and turned seven or seven corners. He came to a tall Soviet-style factory building near which he didn’t get into the car. Li Yuanling pointed to a three-story cement building on the right side of the car and said, "Go to grandpa Wu with my mother first and then take you to see the prototype."
Climb the second floor to Wu Zhonghua’s office located in the innermost corridor. Li Yuanling knocked on the door and Liang Yuan pushed the door and entered the room. Liang Yuan saw a middle-aged man sitting in the reception room. Li Yuanling smiled at Wu Zhonghua and said, "The teacher has guests here."
Wu Zhonghua got up and said to Li Yuanling, "Xiaoling, you’re just in time. I’d like to introduce you to the director of 99 Hong Dagang, who is currently in charge of communicating with the project team on behalf of 99 Institute." Then he pointed to Li Yuanling and said to Hong Dagang, "This is my student Li Yuanling who will lead the gas turbine project from her side in the future."
Liang Yuan listened to the pleasantries of both sides and thought hard for half a day, but he didn’t think of who Daniel was, director of Hong’s past life.
The three adults said a few more words without nutrition. Director Hong got up to leave. Yuan-ling Li looked at Hong Dagang from the window and turned to Wu Zhonghua and said, "Teacher, who is he?" Wu Zhonghua said, "Deputy Director of Logistics and Tertiary Industry of 99 Institute" looked at Li Yuanling’s puzzled eyes and Wu Zhonghua sighed and said, "The project team set up 99 because it is not far from here to produce heat-resistant material Qingyuan Special Steel, and the technical force base of China’s research aviation motivation is here."
"This Spey reform project teacher also told you that it was mainly the Chinese Academy of Sciences that made an experimental project on Industry-University-Research Integration Road. Today, it’s just nothing to take you to see the prototype. After I told you the ins and outs of the project in detail, it’s good to know fairly well that you took over."
Three people out of the office along the cement road into the car Wu Zhonghua pointed to a seven-meter-long huge equipment in the car and said, "This is the prototype that has been completed now." Liang Yuan was a little excited when he looked at the huge equipment in front of him. No one on the whole planet could understand the significance of this machine to China better than Liang Yuan.
Seven, meters long and more than two meters wide, there are many different pipelines in the center of the quiet sleeping car of the gas turbine unit, which extend from the periphery of the car to connect the different positions of the unit. Liang Yuan is close to the unit, reaching out and touching the cold metal with dark light, looking up at the top of the unit close to 4 meters high, thinking that this big guy can have 3 tons of improper things. This huge thing can push tens of thousands of tons of ships to run at 32 degrees after roaring.
Wu Zhonghua took Li Yuanling to a nearby high platform and said, "This project started in 1998 when the Navy planned to modernize the 51-class guided missile destroyer after type 42 destroyer, England. At that time, it was envisaged that the ship’s displacement would reach 41 tons by adopting the ship’s side deck type of Gao Qian, and the heavy-duty" sea javelin "area anti-missile equipment would enable the 51s ship to have a certain sea formation area and strong single-ship anti-war capability. Spey changed the gas turbine into a supporting project to power the Navy’s 51s-class guided missile destroyer."
"In those days, Rolls-Royce Company competed with Ventilation for the power market of Chinese naval vessels and suggested that China introduce the newly-developed Spey **1a gas turbine. Considering the benefits of this project in improving the motive research mechanism of China, the teacher promoted the introduction of this project that year."
Wu Zhonghua raised my hand and pointed to the behemoth in the car and said, "This machine is made by imitating Rolls-Royce company’s Spey **1a gas turbine."
Liang Yuan suddenly felt something was wrong when I heard this. Liang Yuan knew that his mother had changed the specific model data of the gas turbine in Taiwan, and I didn’t know that it was the soil-picking method of the terrapin itself, which would have thought that the origin of this machine was so nb.
Bk, a regular forum mixer, was very familiar with this type of gas turbine. Until the 21st century, the subsequent models of Spey **1a were all our old enemies. When the model was exhibited to Spey **1, the power of a single unit had reached 1,775 kilowatts. After the United States banned 125 gas turbine units, several military fans looked at Spey **1 drooling and said that if our Spey reform project persisted, three units would be merged with two 125 units.
Thank you for your support. Your support is our greatest motivation.
Chapter 19 dispel doubts
After Liang Yuan came to calm down, his mind was clouded with doubts. In his previous life, he changed the gas turbine to Spey. It was a terrapin, a local method and a horse. The network occasionally heard that Spey could not change the climate. After the test run, the fuel consumption was high, the power was low, and the life of the unit was short. It was that Liang Yuan was afraid of his mother’s sadness. These nonsense words have never been mentioned with Li Yuanling. Because of this problem, Hong Kong Liang Yuan had argued with others that new technologies always need to mature. It is normal for the first generation to have defects. Wait, Now I
Wu Zhonghua went on to say, "It’s a pity that in 1992, after the war between Britain and Oman ended, two seriously injured ships sank in type 42 destroyer, England, and a high-level naval officer was dissatisfied. The 51s guided missile destroyer was cut down four years after the key shift of type 42 destroyer’s Inga national economy. At that time, the Spey performance verification machine had been on fire for more than six hours.
Wu Zhonghua looked at Li Yuanling and pointed to the edge machine with doubts and said, "At that time, it was just in time to carry out the restructuring test in the courtyard. Teacher Industry-University-Research Integration applied for the establishment of a restructuring enterprise and found the 423 factory, which belongs to the General Logistics Department, to persuade them to lay the foundation for the horse gas turbine project to show the ship power industry, and promised that after the successful development of the gas turbine, it would be produced by the 423 factory alone. Since then, Spey has changed into a self-financing model for follow-up research."
"After six years in the hospital, I didn’t see the hope of profit, so I gave up the remaining 423 factory. In the future, the naval power manufacturing industry of Nengma struggled to support the original gas turbine and then tested it with the navy’s 53-class frigate. If the navy purchased it, the 423 factory could continue to invest in in in-depth research. Unfortunately, a few days ago, the navy sent a message saying that our progress was too slow. Even if we could achieve the expected goal and reach the original Spey s_1a single-machine unit power level of 13 kilowatts, the navy would not purchase a large number of naval high-level gas turbines
Wu Zhonghua sighed for a long time and said, "Miss Xiaoling didn’t expect that things would become like this just after you were transferred here. Now the gas turbine horse is about to start the ignition test of the whole machine, but the navy has such an accident."
Li Yuanling comforted and said, "Nothing is the worst. I will go back to Peiping with my teacher to do research. Besides, it took only two years from the performance verification machine to the whole machine commissioning, and the teacher’s progress is fast enough."
When Wu Zhonghua heard Li Yuanling say this, he shook his head and said with a wry smile, "Where is our fast progress? The verification machine has been running for 6 hours, and even the life of the compressor after cutting the top has not been done. The power of the unit has exceeded 15 kilowatts, and the design of the air cooling system and the axial force of the motor department has been modified. However, in order to save money, it has been directly finalized after general calculation, and no quantitative verification has been done. For example, there are many cases in which this equipment goes through the whole machine test first, and then where there is a problem, it is the opposite of doing the key component verification first and finally
Wu Zhonghua said with some sadness, "Even if you are impatient to take the naval project, you can’t violate the laws of science. This is not asking for a solution. First, put the whole machine out for trial operation. There is nothing wrong with it. It’s best to have a headache and treat the symptoms. How many years will it take to fully understand Spey’s technology?"
Liang Yuan suddenly realized that it was no wonder that Spey changed the data of the first test run in the past life so ugly. The root of the 423 factory didn’t realize the complexity of production and design of gas turbines. This thing was changed casually. The ugly data of the first test run probably put the blame on Wu Zhonghua. After all, Wu was the project leader, and then the 423 factory withdrew its capital. When the project failed, the navy didn’t look at Spey’s change. This time, the reason was more sufficient. The domestic gadgets just couldn’t work. I gave you the drawings and couldn’t produce 125 gas turbines. It’s even louder. It’s estimated that Wu was hospitalized at the end of the year because of this incident. Finally, he died of overwork for nine years. Liang Yuan listened to Wu Zhonghua and changed the context to guess the past life.
Wu Zhonghua pointed to the foot unit and said, "Teacher Xiaoling originally planned to install two prototypes, one is a simple cycle unit and the other is an intercooled regenerative unit. Unfortunately, the project team is not enough."
Li Yuanling was a little curious and asked, "What is the cost of this unit now?"
"Don’t just mean that this unit is about 110,000 yuan, mainly because our Spey motive production line has been closed, and the gas generator inside is imported from Spey motive, which will take up more than half of it."
Three people turned several times around the machine, and Wu Zhonghua gave Li Yuanling a live teaching. He pricked up his ears and eavesdropped on Liang Yuan, thinking that he was really not doing this job. He looked at his mother and Wu and chatted with Liang Yuan in the car.
Two hours later, Liang Yuan lost interest, and the two men returned to Wu Zhonghua’s office. Wu Zhonghua took out a bag of tea and smiled at Li Yuanling and said, "What about authentic Longjing? Xiaoling, you are lucky."
Liang Yuan looked at his mother with a look forward to it, wondering what his parents love to drink tea. Why are they interested in this quintessence of Chinese culture? The two people still feel that coffee is more suitable for laymen.
Wu Zhonghua slowly poured water into the teapot and looked at the transpiration water mist. He continued, "Just now, Director Hong came to ask about the oil. If the original Spey s_1a runs at full capacity, it will consume 3.2 tons of oil per hour. I asked the 99 Institute to prepare it according to 3 tons per hour."
Liang Yuan was a little confused. Is it that we are more fuel-efficient than the original one and asked, "Grandpa Wu, is our gas turbine more fuel-efficient than the original one?"
Wu Zhonghua haha laughed and said, "Where is our fuel economy? I estimate that our maximum power must be smaller than the original one." Li Yuanling looked at Liang Yuan and was still at a loss. He picked up a pen and paper and wrote a few numbers and handed them to Liang Yuan. Liang Yuan took it and read it. When the maximum power of Spey s_a1 was 13 kilowatts, the fuel consumption rate was 235 grams/kilowatt, Li Yuanling pointed to two data and said, "Xiaoyuan will know the full power fuel consumption by multiplying these two data."
Looking at the paper data, Liang Yuan remembered that the later Terrapin Navy 54 frigate had 27 knots and a week’s sea self-sustaining, and thought that even if it was replaced by Spey s_a1 class gas turbine 54 frigate, the full displacement could be increased from 4 tons to 5 tons, and the combat capability could be increased by 3% at least, and it could fly with the aircraft carrier formation for 3 knots.
Thank you for your support. Your support is our greatest motivation.
Chapter 2 Bad debts
Wu Zhonghua looked at Liang Yuan and studied the data written by Li Yuanling with great interest. He said, "Xiaoyuan, I heard that grandma Liao said that your physics foundation is the best in basic subjects. If Xiaoyuan takes the junior class, he will not choose aviation major."
Liang Yuan scratched his head and said, "I don’t know. My mother said that it takes lasting enthusiasm to engage in this industry. I don’t know how long my interest will last."
Liang Yuan thought that I was interested in motivation and principle, but I was not interested at all.
Wu Zhonghua said to Yuan-ling Li, "On July 7th, the junior class exam of Dongda University was given by Dongda itself this year. The difficulty of the national college entrance examination paper may be slightly higher than in previous years. I asked Ma Tianyuan, who is in charge of enrollment in Dongda University, that Xiaoyuan and a Shengjing candidate are the youngest this year is very dominant."
Li Yuanling said, "I didn’t have any hope. At home, I told him that I decided whether to take the exam or not, and I didn’t look at his bitter face the other day. I had to give up, but I didn’t expect to stick to it."
Liang Yuanxin said that if it weren’t for the influence on your research direction, I would have run back to the stream to flirt with two girls.
Wu Zhonghua said, "These days, Lao Liao is full of praise for making up lessons for Xiaoyuan, saying that Xiaoyuan’s thinking is broad and his thinking is quite jumping. Anyway, Xiaoyuan is still young and can be tested for three or four years."
Liang Yuangang wanted to say that he didn’t try Wu Zhonghua’s desk for the time being this time. Wu Zhonghua picked up the phone and hung up the phone. Then he said to Li Yuanling, "Director Hong of the logistics department said that 99 research turbojet 13 the day after tomorrow, the fuel in the high platform is not enough, so we can get 2 tons."
Li Yuanling asked doubtfully, "Why is there a turbojet project in 99 when the motivation of this turbofan is all gone?"
Wu Zhonghua sighed and shook his head and said nothing.
Liang Yuan thought that the master was really kind, and now there is still no complaint.
With the memory of past lives, Liang Yuan is familiar with the wonderful motive of turbojet 13, which is the thrust upgrade of MiG-21 equipped with R-11F-3 twin-rotor in the 1960s. It is intriguing that this thing was Sperma’s when Ma Liangyuan calculated that the turbojet 13a would pass the national verification, and now it is time for high-speed test.
Unfortunately, the performance of model 13a of turbojet is garbage, which was obtained from Nai Shengjing 99. In 1991, model B of turbojet 13b was developed. In 1996, the high simulation test was carried out for two months, and then it was tested for 15 hours. In 1997, it passed the ground test successfully. In June 1999, it was equipped with 歼 7fs and was listed as a key model by the military in 1999.
