Chapter 322

Shortly after going to work this morning, Liu Chuanhai, the general manager of the aircraft company, and Kong Yuxiao of the technology company came to Lei Tiantang's office to look for him.

"Sit down! You will come to me this morning. Is there anything I can do for you Lei Tiantang asked them to sit down with a smile.

"Well, boss, after the design of our aircraft and rocket is finalized, we need to conduct wind tunnel test. However, our company has not built a wind tunnel at present, so our current design data are only simulated on supercomputers.

However, there may be a big difference between the test data and the actual data. At this time, we need to have a wind tunnel to carry out the relevant test work.

So we are here to ask the boss for help to solve the problem of using the wind tunnel! " Liu Chuanhai said why they came to him this time.

As soon as he said this, Lei Tiantang knew that it was true. It was absolutely impossible to conduct aerospace research without wind tunnel.

The wind tunnel laboratory is a kind of pipe-shaped experimental equipment which can generate and control the air flow artificially to simulate the gas flow around the aircraft or the entity, and measure the effect of the airflow on the entity and observe the physical phenomena. It is one of the most commonly used and effective tools for aerodynamic experiments.

Wind tunnel experiment is an indispensable part of aircraft development. It not only plays an important role in the research and development of aviation and aerospace engineering, but also plays an indispensable role in transportation, housing construction, wind energy utilization and other fields with the development of industrial aerodynamics.

This experimental method is easy to control the flow conditions. During the experiment, the model or object is often fixed in the wind tunnel for repeated blowing, and the experimental data are obtained by measuring and controlling instruments and equipment.

There are many kinds of wind tunnels and there are different classification methods. According to the airflow velocity in the experimental section, it can be divided into low speed, high speed and hypersonic wind tunnels.

"Do you need to do this now? If I need it now, I will go to the government for help.

I remember that our country's wind tunnel is at the leading level in the world. The wind tunnel our company needs should be hypersonic wind tunnel, that is, we need the help of jf12 hypersonic reproduction wind tunnel.

Jf12 wind tunnel has reached the world's leading level: the famous wind tunnel in the United States achieves 4-7 times of sound speed, the nozzle diameter is 1.5 meters, and the experimental time is 30 milliseconds; while the jf12 hypersonic shock wave wind tunnel has the wind speed of 5-10 times the sound speed, the nozzle diameter is 2.5 meters, and the experimental time is 100 milliseconds.

Is it enough for you to do the initial experiments? " Lei Tiantang wanted to say.

"Yes, boss, we have come to you for help in this matter. At present, our two companies have 6 models that need wind tunnel test. However, the schedule of this wind tunnel is full. We applied several times and were rejected. We came to the boss for help when we had no way out!

Since boss, you are willing to ask the government for help, that's great! This wind tunnel is so popular that many research institutions are queuing up to use it for wind tunnel experiments Kong Yu said with a smile.

"Oh, you! that 's ok! I'll let you know when I get in touch! But since you know the importance of wind tunnels, why not suggest that our company build its own wind tunnel Lei Tian Tang asked with a smile the doubts in his heart.

"Boss, it's not that we don't want to, but we don't have this technology. It took more than four years and 46 million yuan to build such an international leading super large test equipment. It's just a miracle.

However, this miracle is not unexpected, because it is based on 50 years of research on hydrogen oxygen detonation and 15 years of exploration on application technology of detonation driven shock tunnel. The earliest team leader is now 85 years old.

This money is nothing to our company, but our company does not have such technology accumulation. It takes a long time to design and manufacture such a large wind tunnel!

So we haven't considered this matter all the time. Of course, boss, what you said is reasonable. We lack of consideration in this respect. Our company really needs to build a wind tunnel laboratory belonging to our company. After all, it is not convenient to use others' wind tunnel, and it is very easy to divulge our research data! " Kong Yu explained with a smile.

"Well, I don't blame you at all. There are too many research work in the company. It's impossible to start all at once. However, since we have found this problem, we have to solve it!

This work is divided into two parts. Our group company must build its own wind tunnel, and the most used wind tunnel in the future should be the aircraft company side, so the company's wind tunnel should be built on the side of the aircraft company.

Manager Liu, after you go back, you can start the preparation work in this aspect. Let the personnel department of the company start to recruit experts and researchers in this field. We need to carry out the research work in this field from now on. In the future, our company will need to use many wind tunnels. It is absolutely unrealistic to borrow wind tunnels from outside for a long time!On the other hand, I'd like to ask if the R & D and construction units of jf12 wind tunnel can help us build a wind tunnel of the same scale, or even cooperate with us to develop a more advanced wind tunnel!

After all, our company is also very powerful. We have great advantages in terms of artificial intelligence and various high-performance materials required for the construction of wind tunnels. Cooperation between the two sides should be a matter of mutual benefit!

I think the possibility of cooperation is very large, but I am responsible for the beginning! You are responsible for the follow-up work! " Lei Tiantang said his plan with a smile.

"Good boss, I will start the work in this field after I go back. If the boss talks about success, it will be great. I will do the rest of the work." Liu Chuanhai said happily.

Having said what he cared about, he left Lei Tiantang's office. He didn't wait for Kong Yuxiao to leave together. It was mainly Kong Yuxiao who had something to look for the boss.

"Boss, I have one more thing to report to you. This morning, I just received a formal notice from the military that our military robots have passed the final scale test, and the military is ready to carry out large-scale procurement.

The day after tomorrow, they will send a delegation to our company to discuss the purchase contract. Do you think you need to come out in person for such an important matter, boss? "
