Siheyuan: My Northeastern Farmhouse

Chapter 329 Return

Because he is going abroad in two days and he is not sure when he will come back, but the development of the five-axis machine tool cannot stop, especially when the supporting computer is already being prepared.

Therefore, Gu Weijun had to quickly prepare the corresponding drawings before going abroad.

When the No. 1 Machinery Factory in Beijing learned that Gu Weijun was coming, Director Li Zhenshun hurriedly took a few more bites of rice and hurried to the workshop.

In the workshop, Gu Weijun was already holding drawings and explaining the key points of processing to the workshop director and master workers. General Engineer Ye and other Tsinghua teachers were also taking notes with them.

After Director Li arrived, he stood quietly on the outside, listening to Gu Weijun's continuous explanation while pointing at the drawings.

Director Li quietly winked at the office staff, and after a while, a tea vat of brewed tea was brought over.

Factory Director Li took it and held it himself. He looked at Gu Weijun as he paused to wait for the technicians and workers to ask questions. He quickly handed it to Gu Weijun and said, "Gu worker, please drink some water to moisten your throat."

After Gu Weijun expressed his gratitude, "Gudu" drank most of the tea in the tea vat in one go, and then returned the tea vat to Director Li.

When faced with questions, Gu Weijun took the chalk and kept writing on the blackboard. Because there are Tsinghua teachers on the front line, many questions can be understood by Gu Weijun with just a few clicks.

In the future, these teachers will join the manufacturing process of five-axis machine tools, which saves Gu Weijun a lot of effort and can be said to be the best of both worlds.

who am I? where am I?

What are these things written about?

They all look like formulas, but why don’t I recognize any of them?

Is the gap between college and university so big?

Yu Qiang secretly comforted himself that his strengths were in foreign languages, and I was definitely better than him in this regard.

Gu Weijun nodded, we are so motivated now, "Director Li, I am going abroad on a business trip in two days, and I don't know when I will come back."

"As long as we conquer this mountain, many foreign countries' technological blockades on our mechanical processing will be in vain!"

In the middle, Yu Qiang pretended to be passing by not far behind Gu Weijun, and took the opportunity to glance at it. His eyes turned black when he looked at the densely packed formulas and calculated values ​​written by Gu Weijun on the paper.

"However, we are not afraid. The teacher said that work is to solve problems!"

"Several of my teachers are busy right now and may not have time to come over and help solve the problem."

"Okay, okay." Director Li's smile turned into a chrysanthemum again, and then he complained a little, "Gong Gu, you said you have such good skills, you led us to conquer the three-axis and four-axis machine tools. Yes, now they are engaged in the fifth axis! Why were you assigned to the Ministry of Foreign Affairs? "

In the afternoon at the Ministry of Foreign Affairs, Gu Weijun took out the old man Qian Weichang's homework assignment, data calculation, and began to do calculations.

In the evening, as soon as he heard the closing bell, Gu Weijun immediately sorted out the calculation data on his desk, packed his bags and left.

Deputy Director Zheng looked at Gu Weijun's back and could only shake her head secretly. She knew a little about Gu Weijun's situation and knew that the work he did was more meaningful than working overtime here, but others didn't know.

If things go on like this, hey

Deputy Director Zheng could only sigh in his heart, hoping that Gu Weijun could maintain such talent and let other leaders and colleagues see it.

Director Li kept nodding, patting his chest and saying, "Don't worry, Gu Gong, this job is very challenging for us!"

"Isn't this a waste? No!"

"However, after all, this is our first trial production of a five-axis machine tool, and it is only the first step in a long journey of thousands of miles, so we must be mentally prepared."

He didn't care about the looks of his colleagues who were still working overtime.

After finishing the mutual compliments with Factory Director Li, Gu Weijun hurried back to the Ministry of Foreign Affairs. During lunch, he also found a place to go into the space and take a bite.

Although Gu Weijun agreed with this in his heart, he definitely couldn't say that. He could only explain: "The country's considerations are actually more reasonable. It can only be said that I can play a greater role on our diplomatic front."

"That's right!" Director Li slapped his forehead, "You are the one!" He gave a thumbs up, "You are first-class in whatever you do!"

Therefore, after quickly explaining the drawings and handing them over to Chief Engineer Ye, Gu Weijun said to Factory Manager Li: "Director Li, I have just explained the five-axis drawings and expected production and processing points."

"In this way, you can find Director Yao Tongbin of the Aerospace Institute. Although he is mainly engaged in aerodynamics, he also researches materials."

"There must be many problems in the middle that need to be solved."

"We Chinese are invincible!"

Shougang, Qian Weichang's office, the fat old man hasn't arrived yet. He has to arrive from Changping around 9pm, sometimes even until 11am.

So Gu Weijun didn't wait in the office. After putting the calculated data on the table, he locked the door and went to Secretary Huang's house in the family area for dinner.

Dinner had already started at Secretary Huang's house. When Gu Weijun arrived, he didn't think he was an outsider. He just picked up the bowls and chopsticks and sat down to eat.

While eating, he asked, "Sister Xiaoxia, when will my brother-in-law come back?" "Didn't we have a show at Zhenbao Island two years ago?"

"Can't you ask for leave?"

Sister Xiaoxia took care of the child while eating, and replied: "I still can't leave there, so I applied for family leave this year and plan to take the baby there to see him."

Gu Weijun glanced at his eldest nephew, who was already 6 years old, and couldn't help but frown, and said to Mrs. Huang and Sister Xiaoxia: "It's very cold there, the lowest temperature can reach minus 40 degrees."

"Let's not take the child with us this time."

After listening to Gu Weijun's words, Secretary Huang and Mrs. Huang also advised Sister Xiaoxia not to take the children there this time.

After dinner, Gu Weijun followed Secretary Huang to the factory director Zhou's house to drink tea and chat. Director Zhou laughed and teased Gu Weijun, "It's better for you. You can go to a capitalist country if you have nothing to do. No wonder you chose to go to the Ministry of Foreign Affairs in the end. ."

Yes, as soon as Gu Weijun heard this, he knew that Director Zhou was still dissatisfied because he could not bring Gu Weijun to Shougang.

Gu Weijun could only shrug and stop defending. He had said it several times before, and Director Zhou just vented a few words casually.

Knowing that Gu Weijun was going to France in two days, Director Zhou and Secretary Huang didn't make any other requests. They just wanted Gu Weijun to see if there was an opportunity to bring back some foreign technology for reference.

Although Shougang has successfully built a 50-ton oxygen top-blown converter, the next target of a 100-ton steelmaking furnace is too big, so it is best to learn from it.

Gu Weijun agreed wholeheartedly, because the relevant information was gathering dust in his space.

It was after 10 o'clock tonight, and the fat old man came to Shougang with his exhausted body. He first took Gu Weijun's calculation paper and briefly looked through it, and then gave him the new calculation data.

When he learned that Gu Weijun was going to France again, the fat old man raised his eyebrows, then shook his head. When Gu Weijun saw it, he immediately asked: "Teacher, what's wrong?"

The fat old man leaned on the sofa tiredly. Gu Weijun habitually massaged the old man's head, shoulders and neck.

The fat old man's voice was slightly hoarse today, "It's a pity that we don't have any information from French aerospace. Otherwise, our road could be smoother."

Gu Weijun was a little confused, "Teacher, isn't our Dongfanghong already in the air?"

"That's just the beginning!" The fat old man's sparse eyebrows knitted together. "The United States has already landed on the moon. The Soviet Union is also preparing to start building a space station. We have just started launching satellites. The gap is too big."

"It is condescending and the threat is too great to allow the US imperialists or the Soviet revisionists to gain the upper hand in outer space."

"We have to catch up!"

Gu Weijun comforted him while massaging: "Teacher, there is no room for sloppiness in scientific research. As long as we take one step at a time and take every step firmly, we will definitely catch up soon."

"You know, we have institutional advantages."

The fat old man turned his head and raised his eyelids to glance at Gu Weijun, "I didn't expect that your speaking skills would improve after you arrived at the Ministry of Foreign Affairs!"

"Okay!" The fat old man patted Gu Weijun's hand twice before standing up and rubbing his temples twice. "Let's compare the wing vibration data sent back by Lao Wu last week."

"Hey, Wu Zhonghua went to Shenyang to transform and upgrade the J-6. It's not easy. The material level is the most difficult."

"By the way, do you have any idea about the materials?"

"Is the material composition I guessed before, and the test results I conducted after calculating the results satisfactory?"

Gu Weijun shook his head regretfully and said with a wry smile: "There are two materials that can meet the engine's high temperature resistance and fatigue resistance requirements after calculation through formulas, but after being refined, the results are very unsatisfactory."

The fat old man sighed again when he heard this, "Basic science like materials does not allow for quick success, so take your time."

"It's a pity that the alloy formulas you obtained from France are not bad. Although they can be put into engine casting, their lifespan is still too short, only about 50 hours, which is not much better than domestic materials."

Gu Weijun quietly rolled his eyes. After all, the improvement has doubled compared to 30 hours, right?

The improved J-6 developed by Teacher Wu is a supersonic fighter.

Then I communicated with the fat old man. Last week, the two of them had not discussed the mathematical problem of aircraft tremor until very late.

After the fat old man went to rest, Gu Weijun also returned to the guest house, locked the doors and windows, and ducked into the daily printing plant.

Repeating the same trick, an article praising Lin on the front page was replaced with: Abolition of traditional Chinese medicine is a capitalist conspiracy.

Gu Weijun touched the stubble on his chin, wondering if there would be any waves when I come back from France?
