Siheyuan: Originally I just wanted to be a little transparent

Everyone who attended the meeting stood up one after another when they saw that leader Lin Shengli had left, left the meeting room in an orderly manner, and went to their respective dormitories.

Pu Siren was alone, walking thoughtfully on the way back to his dormitory.

Suddenly, he was tapped on the shoulder from behind.

This time, Pusi Ren was frightened. He immediately made a fist with one hand, put on a defensive posture, and then turned around slowly and vigilantly.

As a result, he took a look and found that the person who tapped him on the shoulder was Xu Aiguo, who was assigned to a dormitory with him after arriving at the base.

"That Comrade Xu Aiguo, it's you. What's the matter with you?"

After Xu Aiguo heard what Pu Siren said, he asked with a puzzled look: "Comrade Pu Siren, are you okay?"

"I just called you several times from behind, but you didn't respond at all."

Just now, Pu Siren's mind was full of bad thoughts, so he didn't pay attention to whether anyone called him.

Seeing Xu Aiguo asking this, Pu Siren quickly covered it up and said, "Ah, what about that, I'm sorry, Comrade Xu Aiguo."

"I may be a little tired from running all the way and am not in good spirits, so I didn't hear you calling me from behind."

Regarding Pu Siren's statement, Xu Aiguo did not doubt anything, but asked with concern: "It's really tiring for someone who has been riding the train and reversing the car for several days."

"Comrade Pusi Ren, are you okay?"

"Do you want me to accompany you to the infirmary?"

"We all have to pay attention to our health. Don't ruin our health when we first come here and don't wait for work."

Hearing this, Pu Siren shook his head and said, "Thank you, Xu Aiguo."

"There's nothing wrong with me. I just didn't get enough rest on the road."

"I'll go back to the dormitory later and have a good rest. I'll be fine. Thank you for your concern."

Seeing what Pu Siren said, Xu Aiguo didn't insist anymore, and the two returned to the dormitory to rest together.

Early the next morning, Lin Shengli came to the wind tunnel laboratory, which was still just an empty shell.

It didn't take long for everyone to gather here one after another. When it was eight o'clock in a few minutes, everyone had already gathered.

Wei Baoguo took out the roster and after confirming the names of the people present, Lin Shengli said:
  "Comrades, the first task for everyone when they come to our special aviation research laboratory is to set up our wind tunnel laboratory for wind tunnel experiments."

"I think some comrades may be unfamiliar with this wind tunnel laboratory, and they may have never even heard of it."

"But I think comrades who study aerodynamic design engineering should be familiar with this."

"I remember that Comrade Pu Siren who asked the question yesterday studied aviation and aerodynamic design engineering."

"Comrade Pu Siren, come and introduce it to everyone so that everyone can understand what this wind tunnel laboratory we are going to build is."

Seeing Lin Shengli posing the problem to him, Pu Siren was not afraid, but stood up and said openly:
  "Comrades, I believe that many of the comrades present have heard of this wind tunnel laboratory. I am here to make a fool of myself. If there is anything deficient in what I said, please comrades. They can provide corrections and additions.”

"The wind tunnel laboratory is a man-made experimental method that can be used to simulate the airflow around an aircraft or a solid body, measure the impact of the airflow on the solid body, and observe various physical phenomena. It is one of the most commonly used and effective means of conducting aerodynamic experiments. …”

In response to Pu Siren's answer, Lin Shengli nodded.

Although this Pu Siren has secretly rebelled and surrendered to the enemy, but aside from this, just looking at his answer to this question, it can be seen that the basic skills he has learned are still very solid.

It is a pity that such a person is actually a mole.

However, Lin Shengli did not reveal his thoughts.

After Pu Siren finished speaking, Lin Shengli said: "It seems that Comrade Pu Siren's basic skills are very solid."

"Yes, your explanation of the wind tunnel laboratory is quite accurate."

"I don't know if everyone understands it."

"I understand." After Lin Shengli finished speaking, someone echoed.

"Comrades, this wind tunnel experiment is an indispensable part of the aircraft development work."

"It plays a very important role in the research and development of aviation and aerospace engineering."

"I believe that for many of our aviation majors, when you were in school, your teachers told you how our comrades collected and analyzed aerodynamic test data when there was no wind tunnel laboratory."

"It's no exaggeration to say that it's like dancing on the tip of a knife."

"Now, we will build the wind tunnel laboratory belonging to our organization with our own hands."

"Next, let me introduce to you our wind tunnel laboratory."

Hearing what Lin Shengli said, everyone got very excited.

"Comrades, if the wind tunnel laboratory is divided according to the airflow it can generate, it can be divided into low-speed wind tunnels, which generate wind speeds below Mach 0.4; high-speed wind tunnels, where the wind speed is between Mach 0.4 and Mach 4.5; and hypersonic wind tunnels, where the wind speeds are below Mach 4.5. Above Mach [-]."

"And the wind tunnel we are about to build, after completion, the theoretical maximum wind speed it can generate can reach Mach 3.8."

"In other words, our wind tunnel laboratory will be a high-speed wind tunnel."

"It can be said that once our wind tunnel laboratory is completed, we can be said to be at the forefront of the world in terms of wind tunnel technology alone."

After listening to Lin Shengli's introduction, everyone seemed very excited. After all, being able to participate in the construction of a wind tunnel that ranks among the top in the world right away is something I never dared to think about before.

"Okay, comrades, let's just introduce the wind tunnel here first. Do you have any questions, comrades?"

None of the comrades below spoke, but Pu Siren, the conspicuous person, stood up again.

"Director Lin, can we really build this wind tunnel?"

"As far as I know, the first wind tunnel in the world is the one in Yingjiang."

"And the wind speed that their wind tunnel can achieve is only about Mach [-]."

"As soon as we come up, we will build Mach 3.8. Is this really achievable?"

This question of Pu Siren aroused considerable discussion among the comrades below.

I saw a comrade in the crowd stand up and said: "Comrade Pusi Ren, what's the matter with you? Why are you so unfavorable to our Special Aviation Research Laboratory?"

"If others can't make it, then surely we can't make it either?"

"Whatever you do is Yingjiang, Yingjiang's, why, Yingjiang is your father!"

Everyone looked along the sound and saw that the speaker was an old technician transferred from another unit.

Following the words of the old master technician, everyone began to talk about it.

Lin Shengli saw this and said quickly: "Comrades, everyone should be quiet."

"Actually, what Comrade Pusi Ren said just now is right."

"The most advanced wind tunnel in the world is indeed the one owned by Yingjiang, and its wind speed has reached Mach [-]."

"Needless to say, the Mach 3.8 wind tunnel we are about to build. With our existing domestic technology, we cannot build even the wind tunnel in Yingjiang that can reach Mach [-] wind speed."

"So, the overall construction and design of our wind tunnel laboratory was designed and completed by our comrades."

"However, most of the equipment and parts are purchased separately from outside."

"And we spent a lot of effort to purchase these equipment."

"As for the specific situation, due to confidentiality reasons, the superiors did not inform us. I don't know this either."

“I just know there are advanced equipment and parts available.”

"But I believe that with the continuous development of our country's science and technology, we will soon catch up with the international advanced level."

"And we are trying our best to catch up now. Although most of the equipment and parts are purchased, the overall design of this system is also designed by us."

Having said this, Lin Shengli glanced at Pu Siren meaningfully.

"Comrade Pusi Ren, it seems you know Eagle Sauce very well!"

Hearing what Lin Shengli said, Pu Siren quickly explained: "Director Lin, I am not studying aerodynamic design engineering, so when I was in school, I paid more attention to these things."

"You also know that in the university, we can access many foreign journals."

Pusi Ren held on and found a specious reason to come out.

While he was talking, one of his hands was involuntarily held tightly in his pocket.

In fact, he was very nervous now, for fear that others would see something wrong from his expression.

As for Pu Siren's explanation, if the situation were different, Lin Shengli would probably laugh.

But on this occasion, Lin Shengli could only continue to hold it in. Who told him that he still needed to cooperate with this servant to continue acting.

So Lin Shengli adjusted his expression and said: "It seems that our Comrade Pu Siren was still very easy to learn when he was in school."

"Okay, comrades, do you have any other questions?"

"If not, then let's all get to work quickly."

"The equipment is all stored in our warehouse."

"Next, I hope that our comrades can work harder to build our wind tunnel laboratory and complete the installation and debugging of the equipment in the shortest possible time."

After saying that, Lin Shengli took people to the warehouse where the equipment was stored.

Here in the warehouse, the comrades sent by Feng Aimin to help move the equipment have been waiting here early.

Everyone entered the warehouse and was very curious when they saw the wind tunnel equipment placed in the warehouse.

Especially those comrades selected from various universities.

Before this, even everyone was studying aviation-related majors, and they knew there was such a thing as a wind tunnel.

However, that is all understood from the records in books and the descriptions from teachers.

Even most comrades may have never seen pictures of wind tunnel equipment. (End of chapter)
