Chapter 322: New experimental equipment demand-wind tunnel

Not long after he went to work that 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! The two came to me this morning. Is there anything I need to do?" Lei Tiantang asked them after sitting down with a smile.
"It's such a boss. After the design of our aircraft and rockets are finalized, wind tunnel testing is required. However, 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 for related testing.
So this time we are here to find the boss to help solve the problem of using the wind tunnel! "Liu Chuanhai said why they came to him this time.
He knew that when he said Lei Tiantang, it is true that it is absolutely impossible to conduct aerospace research without a wind tunnel.
A wind tunnel is a wind tunnel laboratory. It is a pipe-like experimental device that artificially generates and controls airflow to simulate the flow of air around an aircraft or entity, and to measure the effect of airflow on the entity and observe physical phenomena. , It is one of the most commonly used and effective tools for aerodynamic experiments.
Wind tunnel experiments are an indispensable part of 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, and wind energy utilization.
With this experimental method, the flow conditions are easy to control. In experiments, models or objects are often fixed in a wind tunnel for repeated blowing, and experimental data is obtained through measurement and control instruments and equipment.
There are many types of wind tunnels, with different classification methods. According to the air 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. 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 American wind tunnel achieves 4-7 times the speed of sound, the nozzle diameter is 1.5 meters, and the experiment time is 30 milliseconds; while the JF12 reproduced hypersonic shock wave wind tunnel has a wind speed of 5-10 times the speed of sound , The nozzle diameter is 2.5 meters, and the experiment time is 100 milliseconds.
Its help should be enough for your initial experiments, right? "Lei Tiantang thought for a while and said.
"Yes, boss, we are here to ask you for help on this matter. Our two companies currently have 6 models that need to be tested in a wind tunnel, but the schedule for this wind tunnel is full. We have applied for several times. They were all rejected, and came to the boss for help when there was no other way!
Since the boss is willing to ask the government for help, that's great! This wind tunnel is so popular that many research institutions are queuing to use it for wind tunnel experiments! "Kong Yu laughed helplessly.
"Haha, you guys! OK! Leave this to me, and I will notify you as soon as I get in touch! But since you know the importance of wind tunnels, why don't you suggest that our company build one that belongs to our company? Your own wind tunnel?" Lei Tiantang smiled and asked the doubt 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 for the JF12 wind tunnel and 46 million yuan to build such an internationally leading super-large test equipment. This is simply a miracle.
But this miracle is not unexpected, because it was achieved on the basis of the research and development team's 50-year accumulation of hydrogen-oxygen detonation phenomena and 15-year exploration of detonation-driven shock wave wind tunnel application technology. The earliest team leader is now 85 years old.
This little money is nothing for our company, but our company does not have such accumulation of technology. It takes a lot of time to design and manufacture such a large wind tunnel!
Therefore, we have never considered this matter. Of course, what you said the boss makes sense. We lacked consideration in this regard. Our company does need to build a wind tunnel laboratory belonging to our company. After all, it is not convenient to use other people’s wind tunnels. Not to mention, it is very easy to leak our research data! Kong Yu laughed and explained.
"Well, I don't blame you for this. There are so many research work on the company's side. It is impossible to start all at once, but since we have discovered this problem, we must solve this problem!
We divide this work into two parts to solve the problem. Our group company must build its own wind tunnel, and the aircraft company that uses the most wind tunnels behind it should be the company’s wind tunnel.
Manager Liu, you can start the preparations in this area after you go back. Let the company’s personnel department start recruiting experts and researchers in this area. We need to conduct research in this area from now on. In the future, our company needs to use wind tunnels. There will be so many places, it is absolutely unrealistic to borrow outside wind tunnels for a long time!
On the other hand, let me ask if the R&D and construction unit of the JF12 wind tunnel can 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~EbookFREE.me~ We have great advantages in artificial intelligence and the various high-performance materials required for wind tunnel construction. Cooperation between the two parties should be a matter of mutual benefit!
I think the possibility of cooperation is still very large, but I am responsible for starting! You need Manager Liu to be responsible for the follow-up work! "Lei Tiantang smiled and said his plan.
"Good boss, then I will start working in this area after I go back. It would be great if the boss talks about it successfully. I just leave the rest of the work to me!" Liu Chuanhai said happily.
After talking about the things he cared about, he left Lei Tiantang's office, and did not wait for Kong Yuxiao to leave with him, mainly because Kong Yuxiao had something to find the boss.
"Boss, I still have something 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 talk to us about the procurement contract. Do you think the boss, do you need to come out in person for such an important matter? "
