Chapter 1343 Zheng Gong

To be precise, a wind tunnel is a wind tunnel laboratory. It uses artificial control to generate and control airflow to simulate the flow of gas around aircraft, drones, spacecraft, or cars. Therefore, a wind tunnel is one of the most commonly used and effective tools for aerodynamic experiments.

Before the Wright brothers successfully carried out the world's first powered flight, they built a wind tunnel to conduct various experiments for their aircraft.

Today, wind tunnels are the most widely used tools in aerodynamic research and experiments, and directly serve the development of various aircraft.

In the last century, Uncle Sam's B-52 bomber conducted about 10,000 hours of wind tunnel experiments.

Forty years ago, when the first space shuttle was being developed, it conducted 100,000 hours of wind tunnel tests.

Wind tunnels are generally classified according to the range of flow speed: low-speed wind tunnels, the air density in the airflow is almost unchanged.

Subsonic wind tunnels, the density of the airflow has changed during the flow, roughly in the range of 0.3

Then there are transonic wind tunnels, supersonic wind tunnels, and hypersonic wind tunnels with M≥5.

In recent years, Jiuzhou Technology has invested in more than one wind tunnel in laboratory institutions, equipment and experimental buildings.

But the fact that Gu Qing came in person shows that its importance is definitely not low.

Engineer Zheng's name is Engineer Zheng, but he is indeed the chief engineer of this project.

At the age of 49, he has a scruffy beard like a middle-aged or elderly person in his 50s or 60s.

The middle-aged man wore a straw hat, watched the young president finish his speech, and then tried his best to invite himself to speak a few words, and waved his hand.

"No, no, everyone's time is precious, don't let me waste everyone's time."

Although the attitude of refusal was very real, the middle-aged man was still pushed forward by the students and other colleagues behind him.

In a few steps, he walked to the front of the podium.

"You are the father of this project, and I am just a purse that pays for it. If you don't say a few words, we will feel that today's beautiful sun is missing something."

Gu Qing smiled at the corner of his mouth, and handed the microphone to the middle-aged man whose arms and neck were tanned several shades with a sincere look.

What is success?

Zheng Gong thought that getting into a good university was success, and when he got to university, he thought that getting a doctorate was success.

After working part-time to earn a doctorate, the bright lights, wine, villas, and luxury cars he encountered in his daily work seemed to tell him that this was success.

But how could he make so much money working in a company?

A wrong decision and trusting the wrong people ended up in jail.

When he was released from prison, he found that things had changed and his enemies were in a foreign country. While the rich man was squandering, his relatives had no one to take care of them, and the weeds had grown on their graves.

In the end, it was an invitation letter from Jiuzhou Technology that stopped him from continuing to live in such a muddle.

Taking the microphone and looking at the eager eyes of the crowd, Zheng Gong suddenly became a little timid.

At this moment, the young president behind him whispered, "Come on, you should express what you think, instead of keeping things to yourself."

Keep things to yourself?

At this time, the sun was shining, and the man who was once in the shadows took the microphone, lowered his head for a moment, and finally raised his head.

Perhaps because the face under the straw hat was rarely exposed to the sun, Zheng's facial skin was not even rosy, which formed a bright contrast with the black and red color of his neck. .

"To hollow out a whole mountain can be to mine minerals or build tunnels, but since I saw the wind tunnel in college, I have dreamed that one day I could hollow out a mountain and build the best wind tunnel in the world.

I have come this far, and now let me look back.

The wind tunnel behind me is like a microcosm of my half-life.

I don't know whether I should thank it, or thank myself, or thank everyone, thank the company, and thank Mr. Gu."

At this point, Zheng suddenly bowed to everyone.

The movement was so large that his back was like an old farmer planting rice in the field, solid and so vicissitudes.

And while bowing, the engineer's shoulders were shaking, and crystal tears fell on the ground, breaking out crystal tears.

After the bow, everyone saw that the engineer who had worked in the top unit in the field of wind tunnels was already in tears.

But his voice became more powerful.

"The total number of wind tunnels in the world has already exceeded more than a thousand, but the number is more than the quality.

The largest low-speed wind tunnel is the Guo Jia full-size equipment wind tunnel at the NASA Ames Center in Americus. The experimental section measures 24.4×36.6 meters 2, which can accommodate a complete aircraft.

The Daxia Aerodynamics Development and Research Center located in our Xishu Mountain area is equipped with the largest wind tunnel group in Asia and Europe, 52 low-speed wind tunnels and subsonic, transonic, supersonic and hypersonic wind tunnels, and also has 8 world-class wind tunnel equipment.

And we spent three years under these continuous mountains and finally built the world's most intelligent and most sophisticated sensor top wind tunnel!

The intelligent computing system has a peak computing speed of 50 trillion times per second, and is equipped with three means: wind tunnel testing, numerical calculation, and model flight testing. It can conduct aerodynamic tests ranging from low speed to 40 times the speed of sound, from underwater, ground to 100 kilometers high, covering aerodynamics, aerodynamic heat, aerodynamic physics, aerodynamic optics, and other fields.

To be honest, I can see dense data and piles of drawings as soon as I close my eyes.

As people get older, they tend to be sentimental.

If my mentor were still alive, when he saw this wind tunnel, he would understand that I was wronged at the time! ! !

It's a pity that we all missed it.

Alas. ”

After sighing, Zheng Gong said with emotion: "Classmates, colleagues, friends, if you have ideas about what you want to do, as long as the direction is not wrong, do it boldly and meticulously.

What I regret most in most of my life is that I didn't stand up at that time, and didn't stand up bravely.

Today, this wind tunnel has finally been built. My idea was right. The materials at that time were not up to standard and could not support such a huge wind tunnel building. It even needs more investigation in the Western Sichuan region to find a stable mountain outside the earthquake zone.

Thank you for your company. Thank you. "

Engineer Zheng's speech was not as emotional as those actors, but his tone was more moving.

And the old employees of the wind tunnel project all know that the three years mentioned by this old engineer is ten years of perseverance for him personally.

When he first investigated the area, this old engineer was more familiar with the mountain roads than the local villagers.
