"Da Mao, wake up." When Jiang Yan came to his office, he saw Xu Damao sleeping on his desk covered with clothes.
"You're back, boss." Xu Damao rubbed his eyes after being woken up, and when he looked up, he saw Jiang Yan standing in front of him.
"Have you been waiting here for me?" Jiang Yan asked a little confused.
"Absolutely! Just last night when I got off work, I saw that you still hadn't come out, so I went home and told Grandma Lu that I was going to work overtime, and then I came back on my bike. I was afraid that you would need me to do something, and then I kept Wait here."
"Okay, I'm interested. Have you had breakfast?" Jiang Yan asked.
"Not yet! Boss, have you eaten yet?"
After hearing what Xu Damao said, Jiang Yan thought for a while and said, "I ate some, but I'm not full. How about you accompany me for a bowl of fried liver later?"
After listening to Jiang Yan's words, Xu Damao glanced at Jiang Yan's red eyes and said, "Of course it's okay, boss, but I see that you haven't rested all day and night. Why don't you take a nap and I'll buy some fried liver."
"No, Minister Liu gave us two days off and asked us to go back and have a good rest. There will be tough battles to fight in a few days. You should also take advantage of these two days to have a good rest. You may need to bring some clothes with you when you come. I guess Neither of us can go back anytime soon."
"By the way, this is the pork and rice I just received. Okay, I'll go in and pack it up before we go home. I'm really exhausted this time."
"Boss, go and clean up quickly. I'll take you away when I get back." Xu Damao took the pork and rice from Jiang Yan's hand.
Ever since Jiang Yan taught Xu Damao and the others how to ride a motorcycle, Jiang Yan rarely rode a motorcycle.
"Xiao Yan, here," Jiang Yan had just walked out of the office building with Xu Damao after packing his things.
The windows of an S-type jeep parked in front of the building were rolled down, and the person sitting inside called to Jiang Yan who had just come downstairs.
"Minister Liu." Jiang Yan was stunned for a moment when he saw the people in the car, and quickly walked forward.
"Minister Liu, I don't know if you have any other questions for me." Jiang Yan asked as he came closer.
"Minister Liu, your name is Uncle Liu. This is not a public place."
"Yes, Uncle Liu, I don't know what you are calling me for." Jiang Yan emphasized again.
"Get in the car and let's chat in the car." Liu Xufeng said something that was not what he was asked.
After hearing Liu Xufeng's words, Jiang Yan turned to Xu Damao and said, "Da Mao, you go home first, I'll be back in a minute."
When Xu Damao heard Jiang Yan's words, he nodded, picked up his things and walked towards the place where the motorcycle was.
"I see that you are quite talented in engines, otherwise come here! Don't worry, you are still an engineer here. With my support, you can give full play to your talents."
Sitting in the car, Liu Xufeng spoke to Jiang Yan.
"Farewell, Uncle Liu, you guys have wiped out this little thing in my stomach. I'd better go back to the steel rolling mill! Metallurgy and lathes are my strengths."
"As you can see, many of the things we produce require good machine tools and equipment. We don't have these things, so we can only use local methods. I still want to work hard on one aspect, which can also indirectly help Uncle Liu, aren't you? .”
"No wonder your Uncle Luo said you are a little slippery. Okay, if you don't come, don't come! This machine tool is also a top priority for the country, but if Uncle Liu asks you for help, you can't refuse."
"That won't happen. As long as Uncle Liu asks, I will definitely help," Jiang Yan promised Liu Xufeng.
Are you joking? Jiang Yan has his eye on Ruirui of his family. Liu Xufeng is considered his father-in-law. Although they are not close friends, they still need to have a good relationship.
"I said in the ministry that you have built an oxygen converter. It's a good thing. But I know that several large steel plants in our country have applied to develop this oxygen converter, but you developed it before they even read the plan. Come out, is this thing that good?”
Hearing Liu Xufeng's words, Jiang Yan thought for a while and said to him: "The mainstream of steelmaking abroad now is the oxygen converter, and the domestic open-hearth furnace will eventually be eliminated."
"The cost of building an oxygen converter is much cheaper than an open-hearth furnace. The country can save a lot of money, and the technology can be on par with international standards. More importantly, this oxygen converter is more efficient and can be used in a short time. It can produce the most steel in the country, and it can also save energy significantly and reduce waste loss. It can be said that it kills two birds with one stone."
After hearing Jiang Yan's narration, Liu Xufeng was silent for a moment, and then said: "No wonder Lao Chen is actively promoting this project. Since it has such great benefits, you, Uncle Liu, and I will also support it. When the time comes for the meeting, I will also give it to Huang." The minister will share his views and try to get up early to promote it.”
"Thank you very much, Uncle Liu."
"By the way, Uncle Liu, what major does Ruirui study?" Jiang Yan asked carefully, seeing that Liu Xufeng was in a good mood today.
"You kid, forget it, why did my Ruirui have a crush on your kid? He studied aerodynamics at Tsinghua University."
"Aerodynamics." Hearing this, Jiang Yan froze. He thought she would study some liberal arts subjects, but she didn't expect to study such a major.
Aerodynamics is a branch of mechanics that studies the force characteristics of aircraft or other objects in relative motion with air or other gases, the flow patterns of gases, and the accompanying physical and chemical changes. It is a discipline based on fluid mechanics and grew up with the development of the aviation industry and jet propulsion technology.
"Uncle Liu, why did she choose such a subject?"
Liu Xufeng did not speak when he heard Jiang Yan's question. Instead, he lit a cigarette and took a puff. He finished the cigarette and said, "Maybe it was influenced by his father's sacrifice! His father's sacrifice Under the bombing of the Japs’ planes.”
Liu Xufeng's words reminded Jiang Yan of Cao Bin, who went to SL to study together. His father, like Ruirui's father, was sacrificed by a Japs plane.
As a pseudo-military fan, the computer in my own space contains a lot of aircraft information. There are domestic J5 and J6, as well as several fighter jets and transport aircraft from other countries in the 1950s and 1960s. The MiG series has the most, but That is also a relatively general introduction and some partial drawings.
These drawings were all things Jiang Yan had purchased on the dark web before, which were very confidential things in this era.
Jiang Yan was quite familiar with the J5 produced by the country's imported SL MiG-17 aircraft.
This MiG-17 fighter jet fully inherits the MiG-15's advantages of high flying height and fast climbing speed, but it also inherits its shortcomings such as instability during high-speed flight, easy tail spin and fall, and difficulty in lateral balance.
After the country introduced it, major improvements were made to address these shortcomings. The combat effectiveness of the improved J5 is much stronger than the original version.
Since Ruirui majored in aerodynamics and was destined to work in a research institute in the future, she could unintentionally reveal something that could help better improve the country's war eagle and protect the sky of her country.
Thinking of this, the corners of Jiang Yan's mouth raised slightly.
