I Have a Little Black Hole

Not long after going to work this morning, Liu Chuanhai, the general manager of the aircraft company, and Kong Yuxiao from the technology company came to Lei Tiantang's office to look for him.

Sit down! The two of you came to see me this morning. Is there anything I need to do? Lei Tiantang greeted them with a smile and asked after they sat down.

That's the boss. After the design of our aircraft and rockets are finalized, they need to be tested in wind tunnels, but our company has not built wind tunnels at present, so our current design data are only simulated tests on supercomputers. .

However, the data tested in this way may be very different from the actual data. At this time, we need a wind tunnel to carry out related testing work.

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

When he said this, Lei Tiantang knew that it was indeed the case. It was absolutely impossible to engage in aerospace research without wind tunnels.

A wind tunnel is a wind tunnel laboratory, which is a kind of pipe-shaped experimental equipment that artificially generates and controls airflow, which is used to simulate the flow of gas around an aircraft or an entity, and to measure the effect of airflow on the entity and observe physical phenomena. , which is one of the most commonly used and effective tools for conducting aerodynamic experiments.

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

With this experimental method, the flow conditions are easily controlled. During the experiment, the model or object is often fixed in the wind tunnel for repeated blowing, and the experimental data is obtained through the measurement and control instruments and equipment.

There are many types of wind tunnels, and there are different ways of classifying them. 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 conduct experiments in this area now? If you need it now, then I will go to the government for help.

I remember that our country's wind tunnel is currently at the leading level in the world. The wind tunnel our company needs should be a hypersonic wind tunnel, and that is, we need the help of the JF12 hypersonic reproduction wind tunnel.

The JF12 wind tunnel has reached the world's leading level: the famous wind tunnel in the United States achieves 4-7 times the speed of sound, the diameter of the nozzle is 1.5 meters, and the experimental time is 30 milliseconds; while the wind speed of the JF12 reproduced hypersonic shock wave wind tunnel reaches 5-10 times the speed of sound , the nozzle diameter is 2.5 meters, and the experimental time is 100 milliseconds.

With its help, it should be enough for you to carry out the initial experiments, right? Lei Tiantang thought for a while and said.

Yes boss, we came to you for help on this matter. Our two companies currently have a total of 6 models that need to be tested in the wind tunnel, but the schedule of this wind tunnel is full, and we have applied for several times. They were all rejected, and only came to the boss for help when there was no other way!

Since you are willing to ask the government for help, boss, that would be great! This wind tunnel is so popular that many research institutions are lining up to use it for wind tunnel experiments! Kong Yu smiled helplessly.

Hehe, you guys! Okay! I'll leave this matter to me, and I'll inform you when I get in touch! But since you know the importance of wind tunnels, why didn't you suggest that our company build one that belongs to our company earlier? Your own wind tunnel? Lei Tiantang smiled and asked 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 4 years and 46 million yuan for the JF12 wind tunnel to build such a world-leading super-large test equipment, which is simply a miracle.

But this miracle is not unexpected, because it was achieved on the basis of the R\u0026D team's 50 years of research on the hydrogen-oxygen detonation phenomenon and 15 years of exploration of the detonation-driven shock tunnel application technology. The original team leader is now 85 years old.

This amount of money is nothing to our company, but our company does not have such technical accumulation, and it takes a long time to design and manufacture such a large wind tunnel!

Therefore, we have never considered this matter. Of course, what you said makes sense, boss. We lacked consideration in this regard. Our company really needs to build our own wind tunnel laboratory. After all, it is inconvenient to use someone else's wind tunnel. Not to mention, it is very easy to leak our research data! Kong Yu explained with a smile.

Well, I don't blame you at all. There is so much research work on the company's side that it is impossible to start all at once, but since we have discovered this problem, we must solve it!

We divide this work into two parts. Our group company must build its own wind tunnel, and the most used wind tunnel should be the side of the aircraft company, so the company's wind tunnel should be built on the side of the aircraft company.

Manager Liu, you can start the preparation work in this area after you go back. Let the company's personnel department start recruiting experts and researchers in this area. We need to carry out research work in this area from now on. In the future, our company will need to use wind tunnels. There will be many places, and it is absolutely unrealistic to borrow the wind tunnel outside for a long time!

On the other hand, I went to ask if the R\u0026D and construction unit of the JF12 wind tunnel could help us build a wind tunnel of the same scale, or even go a step further and cooperate with us to develop a more advanced wind tunnel!

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

I think the possibility of cooperation is still very large, but I am responsible for the beginning! The follow-up work needs to be done by you, Manager Liu! Lei Tiantang said his plan with a smile.

Okay boss, then I will start work in this area after I go back. It would be great if the boss talks about success, and I will do the rest of the work! Liu Chuanhai said happily.

After talking about the things he cared about, he left Lei Tiantang's office and didn't wait for Kong Yuxiao to leave, mainly because Kong Yuxiao had something to do with the boss.

Boss, I have something else to report to you. I just received an official notification from the military this morning that our military robot has passed the final scale test, and the military is ready for large-scale procurement.

The day after tomorrow, they will send a delegation to the company to discuss the procurement contract with us. Do you need to appear in person for such an important matter, the boss?
