I have a little black hole

Not long after starting work that morning, Liu Chuanhai, the general manager of the aircraft company, and Kong Yuxiao of the technology company came to Lei Tiantang's office to find him.

"Sit! The two of you came to me this morning. Is there anything I need to do?" Lei Tiantang smiled and greeted them as they sat down and asked.

"It is such a boss. Both the design of our aircraft and rockets require wind tunnel testing after finalization, but our company does not currently build a wind tunnel, 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 the relevant test work.

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

He said that Lei Tiantang knew that, indeed, it is absolutely impossible to engage in aerospace research without a wind tunnel.

The wind tunnel is a wind tunnel laboratory. It is a pipeline-like experimental device that generates and controls airflow manually to simulate the flow of gas around the aircraft or entity, and can measure the effect of the airflow on the entity and observe physical phenomena. , It is one of the most commonly used and effective tools for aerodynamic experiments.

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

In this experimental method, the flow conditions are easy to control.During the experiment, the model or the real object is often fixed in the wind tunnel and repeatedly blown, 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 classification methods.It can be divided into low-speed, high-speed and hypersonic wind tunnels according to the air velocity of the experimental section.

"Do you need to conduct experiments in this area now? If it is needed now, then I will go to the government for help.

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

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 nozzle diameter is 1.5 meters, and the experiment time is 30 milliseconds; while JF12 reproduces the hypersonic shock wave wind tunnel wind speed reaches 5-10 times the speed of sound The diameter of the nozzle is 2.5 meters, and the experiment time is up to 100 milliseconds.

Its help should be enough for you to carry out the initial experiment?"Lei Tiantang thought for a while and said.

"Yes boss, we are here to help you with this matter. At present, our two companies have a total of 6 models that need to be tested in the wind tunnel, but the schedule of this wind tunnel is full. We have applied for several times. They were rejected, and they came to the boss for help when there was no way!

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

"Oh, you guys! OK! I will leave this matter to me, and I will let you know when I get in touch! But since you know the importance of the wind tunnel, why don't you advise our company to build a company that belongs to us early? Own wind tunnel?" Lei Tiantang smiled and asked the doubt in his heart.

"Boss, it's not that we don't want it, but we don't have this technology. It took more than 4 years for JF12 wind tunnel to spend 46 million yuan to build such an internationally leading super-large test equipment. This is a miracle.

But this miracle is not surprising, because it was obtained on the basis of the research and development team's 50 years of research on the phenomenon of hydrogen-oxygen detonation and 15 years of exploration on the application of detonation-driven shock wave wind tunnel technology.The earliest team leader is now 85 years old.

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

So we have never considered this matter. Of course, the boss also makes sense. This aspect is due to our lack of consideration. Our company really needs to build a wind tunnel laboratory that belongs to our company. After all, it is inconvenient to use other people’s wind tunnels. Not to mention, it is very easy to leak our research data!"Kong Yuxiao explained.

"Well, I don't blame you on this point. There are so many research jobs on this side of the company. It is impossible to get started all at once, but since we discovered this problem, then we have to solve it!

We will solve this work in 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, so the company's wind tunnel is built on the side of the aircraft company.

Manager Liu, you can start preparations in this area after you go back. Let the company's personnel department start hiring experts and researchers in this area. We need to conduct research in this area from now on. Our company needs to use wind tunnels in the future. There will be a lot of places, and it is absolutely unrealistic to borrow the wind tunnel outside for a long time!

On the other hand, I will ask if the R&D and construction unit of the JF12 wind tunnel can help us build a wind tunnel of the same size, or even further cooperate with us to develop a more advanced wind tunnel!

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

I think the possibility of cooperation is still very big, but I will be responsible for starting!The follow-up work will require you to take charge of Manager Liu!"Lei Tiantang smiled and said his plan.

"Good boss, then I will start work in this area after I go back. If the boss talks about success, then it will be great. The rest of the work will be left to me to do!" Liu Chuanhai said happily.

After talking about what he cared about, he left Lei Tiantang's office, and did not wait for Kong Yuxiao to leave, mainly because Kong Yuxiao had something to find the boss.

"Boss, I have one more thing to report to you. I just received a formal notice 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 talk to us about the purchase contract. Do you think such an important thing, boss, do you need to come in person?"
