60s researcher

"Are you afraid of Huang Gong?" Lu Jian relaxed as soon as he left the room.

"Hey, that's my elder brother, very serious." He smiled shyly.

"Oh, the same teacher."

"My senior brother is very kind, but he hates me a little bit. I'm always careless and easy to make mistakes." Liang Maoxue looked a little disappointed.

"..." Hearing what he said, Lu Jian was also a little worried. Research work is very afraid of carelessness, and sometimes a wrong memory will waste life and time to find it out.

"Don't worry, it's just what happened before. I don't dare to make careless mistakes now. The consequences are too serious and I can't bear it." You can tell what he thinks by looking at him.

After a few words, he arrived at the place, and Lu Jian opened the door. It was a room of more than ten square meters, which was similar to the office he used before, except that there was an extra desk near the window.

"What punishment?" Lu Jian put the information on the table and continued to ask.

"Hey, Mr. Lu, I'll get you a glass of water first." Liang Maoxue didn't answer, put down the things, and ran out with the cup on the table to pour water, which was prepared by the institute.

"?" Seeing him running out, Lu Jian was a little curious. He didn't dare to say what the punishment was.But he didn't take it to heart, the most important thing now is research.Thinking in his heart, he did it and began to flip through the materials on the chair.

When Liang Maoxue came in with water, Lu Jian had already concentrated on reading the documents, and he was not even noticed when he came in. He put the cup gently on the table, then walked out on his feet, and slowly closed the door .

He was about to go back to his place, but found that there was someone in the office next to Lu Jian, but there was no one when he poured water into it just now, so he stood on tiptoe carefully, preparing to hide.

"Stop, come in." A familiar voice stopped him.

"Hey, brother, what's the matter?" Liang Maoxue hurried in and stood up.

"Did you the day before yesterday..." The corners of his mouth were tightened, and he knew he was in a bad mood just by looking at it.

"No, no, I changed it in less than half a day, and there is absolutely no delay." Before Huang Gong finished speaking, he waved his hand quickly.

"I'll let you off this time, and I know how to check, if there is a next time..."

"There will never be a next time. I don't want to clean the toilet again." Liang Maoxue hurriedly raised his hand and swore that he would never do it.

"You must remember, or you will be asked to clean the toilets of the whole factory next time."

"You said that you have worked for such a long time. There are no big mistakes, but small mistakes. You are still an assistant researcher. Alas!" Huang Gong sighed deeply, his face was full of helplessness, this is his youngest junior, the teacher passed away He had been asked to take care of him before.

"I'm sorry." Liang Maoxue was also very helpless. In fact, he is not sensitive to numbers at all and has strong hands-on skills. Apart from the face of his teacher and senior brother, he was able to sneak in here because of his strong experimental ability.

"The teacher expects a lot from you, you have to work hard, this time Lu Gong is younger than you, you have to learn more from him." Huang Gong patted him on the shoulder, speaking earnestly.

"Yes." Liang Maoxue nodded seriously.

The [-]-ton transport wheel project team has been established for one year, and has accumulated a large amount of information and research results.However, the research on the stern thruster has only been started for half a year, and the design drawings have already come out. However, due to the news from the L Provincial Research Institute, the research team decided to redraw the design drawings, overthrow the previous design, and use hydraulic variable torque propellers.

Lu Jian just sat in the office and read the materials for three hours, and he had a good understanding of the general situation of the project. Just as he stood up and was about to move his body, there was a knock on the door.

"Lu Gong, get ready for a meeting." Lu Jian opened the door and saw Liang Maoxue. He took his notebook and pen and followed him out.

The conference room is on the fourth floor, occupying almost half of the floor. There are more than 200 seats in it. Lu Jian was pulled directly to the thruster research team to sit down. There are about [-] or [-] people in a team. Gong and Huang Gong were also inside, and they fell silent after greeting each other. Director Gui was already on top of the podium.

"Ahem, comrades, this is the 16th progress meeting of our 190-ton transport ship project team since its establishment. Now I will report the latest situation. The preliminary hull structure has passed the preliminary inspection. The total length of the hull is 22 meters. The width is 38 meters, the molded depth is [-] meters, the estimated speed is [-] knots, and the estimated endurance is [-] days. This time we are using segmented forging. Currently, the hull construction is progressing steadily, but the progress of outfitting work... "

"The current situation is probably like this. Next, the leaders of each project team will come up and talk about the progress of the current stage and the goals of the next stage, and which teams need to cooperate." After Director Gui finished speaking, the leaders of each team Everyone came to the stage one by one and began to speak. The meeting continued until mid-10 o'clock in the evening. What was particularly interesting was that someone came in at six o'clock to deliver food, and distributed a piece of corn and a steamed bun to everyone. The meeting was suspended for 10 minutes. Everyone It took [-] minutes to eat and the meeting went on, which was great, not hungry, and they all seemed to be used to it.

By the time the meeting ended, Lu Jian already felt that his mind was full, and it was all about the contents of the [-]-ton transport ship.

When the meeting was over, Lu Jian followed Liang Maoxue back to the dormitory. He had received too much information this day and was really tired, so he washed himself up and went to sleep.

The next morning, Lu Jian went directly to the office where he was staying yesterday, and started to draw the blueprint after getting himself a cup of tea. He was in charge of the hydraulic transmission, which is no longer difficult. The system is already the best that can be made in the current era. Lu Jian has other plans in his mind, but it is a pity that it is difficult to achieve with the current technical level.

Lu Jian had only painted a few strokes before there was a knock on the door. Lu Jian didn't lock the door, he just asked to come in, the door was opened, and it was Liang Maoxue who came in with a notebook in his hand.

"Shall we go to the laboratory now? Team Leader Ma should be there."

"Then let's go now."

Lu Jian put the undrawn drawings into the drawer, locked the door and went to the laboratory with Liang Maoxue. The laboratory is in a building behind the research institute. There are five floors in total. The whole building is a separate laboratory. There are all kinds of equipment inside.

Liang Maoxue took Lu Jian directly to a laboratory on the third floor. There were many people in it. It should be members of the entire thruster team. A group of people were discussing lively inside.

"See Lu, come quickly." Team leader Ma was facing the door, and he saw the two of them as soon as they entered.

Lu Jian walked over and found that they were using models to calculate something.

"You are this?"

"I'm measuring the size of the installation angle." Huang Gong, who was operating the model there, replied, but his hands didn't stop.

Since the propeller's turning resistance decreases due to a decrease in the profile angle of attack, the number of propeller blades increases: when the speed increases, the propeller becomes "light" and the engine produces undesirable "fly".In order to prevent the number of propellers from dropping when the speed decreases, the installation angle of the blade profile must be reduced.In order to keep the number of propellers constant, it is best to have an automatic mechanism so that the installation angle can be adjusted by itself.

"Let's get an automatic adjustment structure." Lu Jian looked at it for a while, and said a word. Before that, torque propellers were rarely used in China, and some researches were the first time.

"Yes, automatic adjustment, why didn't I think of it." Huang Gong patted his forehead, and his whole body became excited.

"Then do this." After solving a problem, Team Leader Ma felt a little more relaxed.

"Lu Gong, you will be in charge of the hydraulic system from now on. You should choose a few people first, these are all seconded..."

"Then let's have a few of them!" Before Team Leader Ma finished speaking, Lu Jian had already selected the people.

"These guys are too young, don't they have much experience?" Team leader Ma was a little puzzled. He pulled Lu Jian out of the laboratory and found a place where there was no one, but asked.He originally planned to let Lu Jian choose two backbones, and then choose a few young people, but he didn't expect that Lu Jian would directly leave a group of young people.

"It doesn't matter, the hydraulic system has been done before, and it is very suitable for the current design. It is not difficult, and it is more hands-on. There is no need to waste people coming here. Let these young people follow suit." Not only for For the task of team leader Luo, Lu Jian wanted to give these people a chance to get in touch with a complete project.

"That's all right, you can bring your people to work too. If you want to do experiments, come to this room, which is dedicated to our propulsion team." Team leader Ma asked Lu Jian to go back after making arrangements.

Seeing that the drawings were not finished yet, Lu let the group of people make arrangements freely and went back to the office by himself.

On the first day of work, Lu Jian had a lot of things to arrange. First of all, he had to draw the blueprints.However, he had already done it once before. Although there were a lot of changes to be made, the progress was relatively fast. It took almost a week for Lu Jian to draw the entire blueprint.

According to his design drawings, Lu Jian quickly led people to make the entire hydraulic system, and the whole process only took one and a half months.In order to adapt to underwater operations, the sealing has been specially strengthened, and many changes have been made in other places to make it more suitable for variable torque propellers.

The variable torque propeller can not only make full use of the power of the main engine, but also improve the maneuverability of the ship and save fuel.But the manufacturing is also more complicated, and the processing requirements are very high. I heard from Liang Maoxue that Team Leader Ma and the others have been in the workshop for several days and have been making paddles there. Lu Jian wanted to report the work progress, but he didn't see anyone.

Lu Jian had been here for almost two months, and he still missed the agricultural machinery project of the electrical appliance factory, so he decided to go directly to the workshop to find Team Leader Ma.

When Lu saw it, the workshop was very lively.

Under the leadership of Liang Maoxue, Lu Jian quickly found them. At this time, a group of people were surrounding a huge propeller, seeming to be discussing something.

"Team Leader Horse." Lu Jian called out and walked over.

"Gong Lu, why are you here? Are you finished with the hydraulic system?" Team leader Ma also heard from Liang Maoxue that Lu Jian's progress was very fast. He thought it would take two months at the earliest, but he didn't expect to find it now. coming.

"It's finished, it came according to the drawings. Is this a variable-torque propeller? The length and distance..." Lu Jian approached and found that the propeller blades were a bit strange, which was very different from the ones he had seen in the materials before. different.

"Lu Gong also thinks there are problems with the length and distance?" Team leader Ma was a little surprised, but he didn't expect Lu Jian to have an opinion on this.

"This is a four-bladed propeller, right? The length seems to be a bit small, at least 2.3 meters, and the distance is not enough. It is best to weld stainless steel screws in this place." Lu Jian pointed to the screws at the root of the propeller.

"Any other questions?" Seeing him stop, Team Leader Ma quickly continued to ask.

"This propeller needs to be launched into the water, and it uses a superior hydraulic system, so sealing is the most important thing. The static side of the sealing ring should be coated with sealant, and there is also a sliding surface..." Lu Jian carefully recalled the materials he had read before. , and some of the issues related to this have been said.

"Lu Gong, do you understand the variable distance mechanism?" Huang Gong suddenly asked a question.

"?" Lu Jian was a little puzzled, not knowing why he asked this question.

"I heard that Professor Xie has a lot of research on this aspect. You are his student, so you should know about it too?" Huang Gong stared at Lu Jian with some expectation in his eyes.

"I have a certain understanding." Lu Jian was a little confused, why is Professor Xie so famous, everyone knows him everywhere.

"Team leader, it just so happens that Lu Gong's hydraulic system has been finished, so let him come to my side and help with the pitch-changing mechanism. We are short of manpower now."

"Lu Gong, why don't you just stay for a while. Although the hydraulic system seems to be fine now, after all, it hasn't been tested on the propeller yet."

Team leader Ma has long known the purpose of Lu Jian's visit, but it is impossible to let him go now.

"Okay." After all the words were said, Lu Jian could only agree.

"Hey, it just so happens that they are busy here. Let's go back and discuss what to do next. I read a paper written by Professor Xie before, which said..." Before everyone could react, he pulled Follow the people away.

"Hey..." Team Leader Ma yelled, but he was already far away.

"This old Huang, why is he acting strange recently?"

"It seems that he is a little anxious. His progress in that part has not been smooth. I have seen him squatting in the office and smoking a few times." Zhang Gong on the side said with some uncertainty.

"Liang Gong, it's not easy for your senior brother. You should pay more attention to him in the future and be more serious in your work. Don't always cause trouble for him." Team leader Ma walked to Liang Maoxue and whispered to him.

"Understood." Liang Maoxue lowered his head, feeling very uncomfortable. Since the teacher passed away, the senior brother has been caring and taking care of him. He made so many mistakes and it was the senior brother who helped him solve them.

"By the way, has Lu Gong encountered any problems recently?" Seeing that he was obedient, Team Leader Ma asked another question.

"Shouldn't there be? Lu Gong has been going well recently, and the project is done quickly and well, but he often says that he has finished reading the book and has no books to read." Liang Maoxue thought about it carefully.

"That's it." Team leader Ma finished his sentence and walked away with his hands behind his back.

Liang Maoxue stared blankly at his back.

"What are you still standing here for? You're following Gong Lu!" Zhang Gong pushed him. Sometimes this kid doesn't wink.

Liang Maoxue came to his senses, ran quickly, and finally caught up with the two people who were discussing the problem halfway.Huang Gong looked back at him and didn't speak. He continued to talk to Lu Jian, but he didn't care. He followed behind and listened quietly, taking out his notebook and notes from time to time.
