After the long entrance ceremony, which was like an old lady's feet wrapped in a cloth, Zhou Yan's career as a research monk has officially begun.
Research monks, research monks, as the name suggests, are monks who focus on research, not students.
Compared with the undergraduate stage, the study at the postgraduate stage is naturally different: at the master's stage, you only need to complete 30 credits in two to two and a half years; if you want to graduate, you can only write a thesis.
, or get results.
Although Zhou Yan had the ability to pass the "entry test" of senior brother Wu Jingchen, in order to enjoy a comfortable graduate campus life, Zhou Yan decided to go step by step and earn credits first.
Unfortunately, things didn't go as planned. As soon as the two theoretical classes on socialism with Chinese characteristics ended, I left the teaching building and before I could pick up my car, I was blocked at the door by my senior brother Wu Jingchen.
"Zhou Yan, how much do you know about the three-dimensional flow theory of impeller machinery?"
Zhou Yan saw that Wu Jingchen's face was serious and it didn't look like he was joking. He hesitated for a moment and nodded: "I guess I understand!"
The three-dimensional flow theory of impeller machinery was proposed by the late academician Wu Zhonghua, a great master of fluid machinery, in the 1960s and 1970s. Although 60 or 70 years have passed, after entering the 21st century, aviation engines are still the
Basic theory of gas turbine and steam turbine design.
The first time Zhou Yan came into contact with the three-dimensional flow theory of turbomachinery was in a copy of "Son of the Wind" Kelly Johnson. Later, after joining the Air Force, he studied it on and off for many years.
"That's great," Wu Jingchen patted Zhou Yan's shoulder happily, "Report to the core computer laboratory in the afternoon."
Just two steps out, Wu Jingchen turned back and said, "Forget it, now come with me to take a look!"
As a 211 University, Shouhang's laboratory is naturally much more luxurious than Shuangfei's Yunzhong Industry. It is also an engine laboratory. In the laboratory of Yunzhong University of Technology, the most luxurious equipment is an internal combustion engine recovered from a car scrapyard.
In the aviation engine laboratory of the first flight, there are working machines.
Perhaps because of confidentiality, the core machine in the laboratory doesn't even have a name. There are only a group of seniors and seniors in white coats, holding notebooks, surrounding the machine and recording something...
Before entering the door, Wu Jingchen handed over an access card: "Solve the problem first, conduct confidentiality training, and we will talk about it after a while!"
Zhou Yan took the access control, thought for a moment, and tried: "My confidentiality level is B2, and I have received confidentiality training before."
"That's good!" Wu Jingchen rubbed his hands, "I'll just tell you why the boss recommends you. That's easy to explain!"
"We encountered some problems this time. Within a specific speed range, the flow fields between the compressor stages are incoherent..." While speaking, Wu Jingchen kept staring at Zhou Yan and noticed that the junior student's face was full of
Everyone can understand, "Now, I am bringing you here because I hope you can help calculate the data..."
"By the way, have you used openfoam?"
"Used..."
After entering the laboratory, Zhou Yan found that a group of senior brothers and sisters were playing with the UGT-gas turbine compressor.
However, when he looked closer, Zhou Yan found that the compressor of the UGT-gas turbine, which was jokingly called a black dog head, had been damaged beyond recognition, and it looked a bit like the QC-280 he had seen before.
The ugt-gas turbine was an unfinished work before the fall of the Red Empire. Although it has been continuously improved by Shuguang Society and has matured, it is a design of the last era after all. Compared with the lm2500 of the beautiful country, it has already improved a lot.
gap.
And Zhou Yan's group of senior brothers and sisters are working here to improve the already outdated gas turbine...
Zhou Yan is no stranger to ugt-. Among the rewards of the previous system mission "Turbo Machinery of the Red Empire", there is ugt-'s prototype da-80; in the mixed martial arts copy, the worker bee also got a complete set of drawings of ugt-
.
Zhou Yan also played UGT- in the virtual space, and even modified the machine so that the output power reached an abnormal 50MW.
"Zhou Yan, this is the test data of the equipment when the air intake volume is 91.2 kilograms per second. Could you please do a simulation..."
Zhou Yan took the notebook handed over by Wu Jingchen, placed it on the table aside, stared at the test data on the side, and activated the "tentacle monster" skill.
In the laboratory, everyone else said nothing, staring straight at the screen, their hands typing on the keyboard, making a burst of exchange rate sounds...
The flow field was quickly simulated, but the result was not very optimistic: there was a problem with the blade shape design of the compressor.
Moreover, according to Zhou Yan's experience, the blade strength of the UGT gas turbine should not be enough to support the air intake of 91.2 kilograms.
Just when Zhou Yan was hesitating whether to tell Wu Jingchen, the experiment was stopped.
A group of senior brothers and sisters in white coats rushed over and opened the cover of the testing instrument...
"The blades are not strong enough..."
Wu Jingchen looked back at Zhou Yan, who was watching the excitement with his head stretched out: "Is the data simulation finished?"
Zhou Yan turned the laptop screen around.
Wu Jingchen glanced at the simulation data, looked at the group of people staring at him, and shook his head helplessly: "The blade efficiency is still a bit low, let me ask the boss..."
With that said, Wu Jingchen picked up his mobile phone and called Liu Yiming: "Hey, teacher, the test results are out. They are still not very satisfactory. The blade strength is still a bit insufficient, and the flow field is still a bit unsmooth..."
"Zhou Yan?" Wu Jingchen turned back curiously and looked at Zhou Yan, who was looking around, "Um..."
"Okay, yes!"
After hanging up the phone, Wu Jingchen took a deep breath. He took a step forward and looked at Zhou Yan quietly.
To be honest, Wu Jingchen didn't know why the teacher asked him to get the answer from Zhou Yan.
Although the guy in front of me is a rich man and has a rich knowledge base on aviation engines, there is a difference between theoretical knowledge and practical reality.
Take the compressor blades as an example. There will only be theoretical designs in textbooks, and there will only be a few typical outdated blade shapes, but not the blade shapes you need.
Although he didn't quite understand, Wu Jingchen still decided to ask without shame: "Junior, the teacher asked me to ask you just now, about the blades of the compressor..."
Zhou Yan was stunned for a moment, then raised his head and looked at Wu Jingchen in surprise: "Teacher asked you to ask me?"
Wu Jingchen nodded: "Our team has been stuck in this link for three or four months. We have learned many plans. As you can see, the results are not ideal..."
"In that case..." Zhou Yan thought for a while, "I will go home and do some research in the afternoon and give you an answer later..."
After leaving school, Zhou Yan went to Kenda University to pick up his girlfriend. After returning home and having lunch, he sat in front of the computer and called up a lot of ugt-'s improvement plans from his database.
For a version with an output power of 32mw, find out the blade shape design of the compressor.
Finding out the blades was naturally not enough, but also required the process information of the blades. Zhou Yan sorted out his memory and found a copy of the titanium alloy hollow blade casting and shot peening process from the titanium alloy kingdom of the Red Empire.
I sorted out the two documents, packaged them together and sent them to Wu Jingchen.
After Wu Jingchen got the information, he transferred it to Liu Yiming: "Teacher, this is the information sent by Zhou Yan!"
"There is no problem with the processing and strengthening process of the blades. You can experiment with the remaining leaf shapes yourself..."
So, the next day, Zhou Yan was pulled into the laboratory again to do simulations...
