Chapter 1012 Wind Tunnel Laboratory

"You've never seen an engine like this, so how did you come up with the idea of designing an aero engine like this? Liu Tianming looked at Zhao Zhongyao and asked again.

Zhao Zhongyao listened to Liu Tianming's words, he smiled and said, "Haha, Director Liu, if you ask me like this, I don't know how to answer." I can only give you an analogy. Let's say a musician writes a song, and if you have to ask him how he wrote it, he won't be able to tell. ”

After listening to Zhao Zhongyao's words, Liu Tianming didn't want to ask anything anymore, he looked at Zhao Zhongyao and said, "Okay, since you said so, then I won't say anything." Anyway, as long as you research out this new aero engine, you'll be fine. ”

Zhao Zhongyao listened to Liu Tianming's words, looked at him again and said, "Okay, now the core components of the new fighter we want to study have been researched. This core component will not only allow us to quickly develop a new type of fighter, but also fill the gap in our country in this regard. With this aero engine, we can completely change the status quo that our country cannot produce aircraft by itself, so that our country can also enter the ranks of developed countries in the aircraft production industry. ”

"Zhongyao, what you said makes too much sense. So what should we do next, the core components have been produced, so the next step is to start the production of the whole machine. Liu Tianming looked at Zhao Zhongyao again and said.

"Of course, this core component has been produced, so the next thing we need to do is to produce the whole machine. However, the first aircraft we produced could only be regarded as a prototype. It's not really a stealth fighter. We can only produce the first experimental machine by developing the prototype first, and letting this prototype be tested in the wind tunnel. ”

Zhao Zhongyao also knows a lot about aircraft design. After all, he also learned a lot of useful knowledge from the 'Zhuhai Aviation Academy'.

"Okay, let's do everything as you say! Then our next step, is it necessary to build a wind tunnel laboratory first?" Liu Tianming listened to Zhao Zhongyao's words, and said again.

"Of course, without the wind tunnel laboratory, we would not have been able to conduct production experiments on aircraft. Airplanes are meant to fly in the sky. It wouldn't be too dangerous if you didn't do a wind tunnel experiment first and take off directly. Zhao Zhongyao looked at Liu Tianming again and said.

"Zhongyao, then you say how to build a wind tunnel laboratory, we will listen to you. Now the most capable talent in our General Armament Department is you, Zhao Zhongyao. Whether our new stealth fighter can be produced or not depends on you. Just talk about how to build this wind tunnel laboratory!" Liu Tianming looked at Zhao Zhongyao again and said.

"That's right, to build a wind tunnel laboratory, we need to design a drawing first, and we have to build a building, just according to the drawings. Zhao Zhongyao said again.

"Okay, everything is as you say, then your next step is to draw the design of the wind tunnel quickly. Let's find some workers and build according to the drawings. Liu Tianming said again.

"Okay, then let's hurry up and do the next step!" Liu Changyun didn't speak for a long time, and now he also said a word.

After Zhao Zhongyao listened, he looked at Liu Changyun again and said: "Minister Liu, our new aero engine has been developed, which can be regarded as a substitute for a gap in the country." We also want to repay this merit from the higher-level leaders, and let them know that our General Armament Department has made great contributions to our country in the study of aero engines. ”

"Okay, leave this matter to me! I'll tell my superiors about it. Liu Changyun looked at Zhao Zhongyao again and said.

In this way, Zhao Zhongyao began to design the wind tunnel laboratory. Liu Changyun, on the other hand, reported to the higher-level leaders the things they had already researched on the new aero engine.

Word of this spread very quickly. Originally, Zhao Zhongyao's previous development of a new aero engine had already been known to many media. Now I heard that Zhao Zhongyao had developed the aero engine that everyone was looking forward to. As a result, the media that had reported on Zhao Zhongyao before began to write about it again.

Zhao Zhongyao has already developed a new type of aero engine. He no longer thinks about studying aero engines. I just thought about designing the wind tunnel laboratory, so that I could hurry up and build this laboratory

It turned out that the laboratory they used for research was an experimental building that had been built a long time ago. It's just been renovated and turned into a laboratory for the study of aero engines.

However, in order to study the flight status of the new stealth fighter in the air, it is necessary to build a new wind tunnel laboratory. In the General Armament Department, there are no such large laboratories, and there are no such large facilities as wind tunnels.

Zhao Zhongyao is now just concentrating on the design of the wind tunnel laboratory. Liu Changyun, on the other hand, went to the capital and began to report their research results to the leaders.

The news that Zhao Zhongyao had successfully developed a new type of aero engine soon spread throughout the capital. Now, Zhao Zhongyao's name is almost as famous as a star.

Chen Yuanfeng, Lao Liu and Lao Li are also full of energy, wanting to research a new type of aero engine. But they worked hard for a month, and it didn't get anything. As for the new aero engine, Chen Yuanfeng knows too little. They have no idea how the world's most advanced aero engines were developed. It's just that I'm not convinced, so I do such a thing.

Now Chen Yuanfeng: They haven't drawn the design drawings yet. I heard the news that Zhao Zhongyao had successfully developed a new type of aero engine.

This news can be said to be a heavy blow to Chen Yuanfeng, Lao Liu and Lao Li. Originally, they were full of passion and wanted to develop a new type of aero engine. But they worked hard for a month, and they didn't get anything at all, which didn't make them very angry.

"President Chen, it seems that we have made a mistake in this step! Zhao Zhongyao has already developed a new type of aero engine. It seems that the fact that people have said that they have made a major breakthrough in research is not a gimmick, but a real thing. Of course, Lao Liu also heard that Zhao Zhongyao had developed a new type of aero engine. Now that he came to Chen Yuanfeng's office, he told him what he knew.

"Of course, I also know about this, but I really can't imagine it! We have been studying for a month, and even the drawings have not been designed, and Zhao Zhongyao has already successfully developed a new type of aero engine, and this guy is really a genius. ”

Before, Chen Yuanfeng also didn't believe that Zhao Zhongyao could really develop a new type of aero engine, but now when he heard the news that Zhao Zhongyao had developed a new type of aero engine, he was also very surprised.

"Yes, we underestimated this kid before, but he really has the ability. It was possible to develop a very advanced aero engine. Compared with others, it seems that we are really far behind. Lao Liu looked at Chen Yuanfeng again and said.

"Yes, we don't have a single aviation expert in the entire 'Beijing Science and Technology Institute' who can be compared with Zhao Zhongyao. People are the real aviation experts. Chen Yuanfeng said again.

"President Chen, what should we do next, should we continue to research new aero engines? Lao Liu looked at Chen Yuanfeng again and said.

Chen Yuanfeng thought for a while and said: "It seems that there is no need for us to study new aero engines. Zhao Zhongyao has already developed a new type of aero engine, so what is the use of our research. Not to mention whether we can develop a new type of aero engine. Even if it is developed, it will definitely not be as advanced as Zhao Zhongyao's research. ”

Chen Yuanfeng and Lao Liu not only knew that Zhao Zhongyao had developed a new type of aero engine, but also knew that the new type of aero engine developed by Zhao Zhongyao was a very advanced turbofan engine. It can be said that in this world, there is no such engine yet.

In this world, although there are also jet fighters. But the aero engines on those jet fighters are just jet engines that are not very advanced. Compared with the turbofan engine designed by Zhao Zhongyao. Whether it is in power or performance, it is much worse.

"President Chen, if you say that, then I'm afraid that our newly established research institute will have to be withdrawn! If we continue to study like this, there will be no research results. ”

Lao Liu himself is an aviation expert, and he knows that it is very difficult to develop an advanced aero engine.

"Yes! If we continue to study like this, I'm afraid it's useless, so I think it's better to withdraw this research institute!" Chen Yuanfeng listened to Lao Liu's words, and echoed like this.

In this way, Chen Yuanfeng spent a lot of manpower, material resources, and financial resources on this newly established aero engine research institute, and after a month of work, it was abolished. It's as if they didn't do this thing at all.

With such a toss, Chen Yuanfeng made the superior leaders very angry. When he reported to his superiors that he had withdrawn the aero-engine research institute they had established. His leaders were angry. In person, Chen Yuanfeng was taught a lesson.

Although Chen Yuanfeng was also very angry, he didn't dare to quarrel with the leader, so he could only swallow his anger and let the superior leader teach him a lesson.

Chen Yuanfeng's result of this contest with Zhao Zhongyao made him deeply feel that Zhao Zhongyao was a person he couldn't provoke, and it was best not to fight with him in the future.

Besides, Zhao Zhongyao is now fully engaged in the design of the wind tunnel laboratory, because he already knew this kind of thing very well during his lifetime. Now it's not difficult to design another wind tunnel laboratory.

The wind tunnel laboratory is one of the most commonly used and effective tools for conducting aerodynamic experiments, which is used to simulate the flow of gas around an aircraft or entity, and to measure the effect of air flow on the entity and observe physical phenomena.

Wind tunnel experiments are 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 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 measurement and control instruments and equipment.

In order for the experimental results to be accurate, the flow during the experiment must be similar to the actual flow state, that is, the requirements of the similarity law must be satisfied. However, due to the size and dynamics of the wind tunnel, it is difficult to simulate all similar parameters in a wind tunnel at the same time, and it is usually necessary to select some of the similar parameters with the greatest impact according to the topic to be studied.

In addition, the quality of the flow field in the wind tunnel experimental section, such as the uniformity of the airflow velocity distribution, the deviation of the average airflow direction from the axis of the wind tunnel, the pressure gradient along the axis of the wind tunnel, the uniformity of the cross-section temperature distribution, the turbulence and noise level of the airflow, etc., must meet certain standards and be checked and measured regularly.

After a week of hard work, Zhao Zhongyao has completed a wind tunnel design drawing. After he finished drawing this wind tunnel design drawing, he took it to Liu Tianming and asked him to take a look at it first.

"Director Liu, how about the wind tunnel laboratory I designed this time, isn't it very advanced! With this wind tunnel laboratory, we can first develop a prototype of a stealth fighter and conduct experimental flights in this wind tunnel laboratory. ”

Zhao Zhongyao knew that he wanted to develop a very advanced fighter. This wind tunnel laboratory is essential. This is because when an aircraft flies in the sky, it encounters a variety of weather conditions.

And this kind of weather situation is not so easy to encounter on the ground. But the plane flies in the sky. Before we send an airplane into the sky, we must let it fly a lot in the wind tunnel before we can decide whether to send this plane to the sky.

The wind tunnel laboratory is to obtain all the situations that an airplane may encounter when flying in the sky. As long as you understand all the situations that the plane may encounter during the flight. to design a very advanced fighter. Let this fighter have the ability to surpass ordinary aircraft in actual combat.
