Chapter 267

"This This This... "

Meng Jianglin watched the leaders coming to their booth, turned around and ran to the booth of Tengfei factory. He opened his mouth for a long time, but he didn't come here.

I can't help it. He still doesn't understand how the circle of Tengfei factory is blowing. Isn't it blowing with his mouth?

It's not only Meng Jianglin, but also the leaders who surround the booths of Tengfei factory are more curious. Let's not say whether the wind is comfortable or not. The key is where the wind comes from.

You know, the washbasin like circle is really empty, there is no fan rotation, there is wind constantly gushing out, it is refreshing these people's three views.

"Dear leaders, the W-8 vaneless fan in front of us is another successful attempt of our factory in civil products after digesting and absorbing the latest aviation power technology."

As soon as this remark came out, the people who were still around the leafless fan were immediately attracted by Zhuang Jianye's words. They couldn't help but listen to it. The latest aviation power technology makes people reverie. Combined with the incomprehensible leafless fan in front of them, they immediately attracted the eyes of all the people around them.

What Zhuang Jianye wants is this effect. Naturally, he doesn't have stage fright. He motioned to master Ju, who was surrounded by a group of leaders and was a little stunned: "then take out our model."

"Ah ~ ~ Oh!"

as like as two peas, the master of the master's subconscious mind was forced to take a mechanical squat down, and put up the model placed under the showcase, uncovering the snake skin bag wrapped on it, revealing a model similar to the leafless fan that was slowly blowing along the side.

The people around them are very curious. They take real objects for the exhibition and sale of electric fans. They also see people using models for the first time, but they are even more curious.

Zhuang Jianye didn't let people's curiosity last too long, so he touched the circle of the model, immediately removed a section, pointed to the cross section inside and said to the people, "please see, this circle is a supply air channel. It's not complicated, but it's actually the crystallization of the latest aviation engine cooling technology, which is ejector technology."

"Little comrade, the ejector technology is not simple, especially it is a very effective cooling mechanism on the small aero-engine used for missiles. But what do I think? You are not quite the same as the ejector I have seen?"

As soon as Zhuang Jianye's voice came to an end, a middle-aged man with glasses and gentle manners frowned and asked. People around him also thought that the middle-aged man had made a lot of sense and nodded subconsciously.

I can't help it. Although these people are cadres with positions in various ministries and commissions, most of them worked in the first-line factories of national defense and military industry in their early years, and even served as the core or leader of important technology projects.

So it's impossible to fool them with some specious concepts, because they have so much ink in their stomach that they can drown people.

No matter how much ink they had in their stomachs, they couldn't stand Zhuang Jianye's cheekiness. He felt on the base of the fan, took apart a cover, took out a delicate small motor from it, and then held it in the palm of his hand and presented it to the public.

The middle-aged man who asked the question just now squinted, then stroked his glasses. There was a trace of surprise in his eyes, and he asked: "this is Turbofan power plant

Other people who know how to do the same look at Zhuang Jianye, no way, it is the hands of that little thing how to look like a concentrated turbofan engine.

Zhuang Jianye shook his head with a smile: "we use the turbofan device of the turbofan engine to build an innovative motor, and then use the small jet powered ejector cooling principle of the missile, and use the air absorbed from the bottom of the absorption motor to enter the closed ring and spray out the airflow. At the same time, due to the principle of the ejection effect, the natural and fresh air will continue to flow I'll send it to you through this ring. "

The so-called ejection effect is a unique principle of fluid mechanics, which means that the velocity is faster than the surrounding fluid and drives the surrounding fluid to flow together. The change of the surrounding pressure of the high-speed fluid has a drainage effect on the surrounding fluid.

It is widely used in many fields, such as aviation, shipping and so on. The ejector mentioned by Zhuang Jianye is one of the applications of the ejection effect. Because the small jet power unit for missile is generally airtight, the traditional air cooling can not meet its needs.

Therefore, the ejector based on the principle of ejecting appears. Through its own high-speed air flow, it drives the surrounding air flow to cool the engine itself through the ejector.

In addition, in the new century, the ejection effect is also applied to the infrared stealth of the fourth generation (also known as the fifth generation), that is, a device with ejection effect is installed at the tail nozzle of the aircraft to cool the high-temperature gas with high-speed flow of cold air (j-20 has applications).

As for navigation, let alone the pumping device behind the submarine, is a typical application model of the ejection effect.

There are many experts in this field around. Even if they are not experts, they will be understood by senior people nearby. So after listening to Zhuang Jianye's introduction, curious people suddenly realize that the so-called leafless fan is not really leafless. It is just a structural innovation based on the principle of aero-engine.Once the secret is revealed, there will be no interest, just like magic. When performing, all kinds of magic are amazing, but as long as the door is open, it will be sneered at.

It's the same with the people around Tengfei factory. They just gather around because of curiosity. But now the answer has been revealed. There's nothing new to say. Naturally, they lack interest.

As for the more lively peers, they feel that Zhuang Jianye is really a gift from heaven.

It's good to make a simple introduction to the functions of such a good thing. The baby has gone all the way in one step, and has completely removed the structure, principle and technical features inside. They don't know what the leaders are feeling. Anyway, they have gained a lot.

So, Meng Jianglin, who was going to go back and make imitations in private, was everywhere. One of them, Baba, came to watch the excitement. Before he finished listening, he asked the office director around him, "do you write it down?"

The director of the office nodded, "I've got it." Then he handed his notebook to Meng Jianglin and said, "wait till you go back and study it. Oh, Zhuang Jianye is in a hurry to go to a doctor. Such a good thing is open to the public. Ha ha, if you don't have to blind him." Meng Jianglin took it over and turned it over. His mouth immediately grinned to the root of his ears.

Looking at Tengfei factory, there is no secret. When you are ready to leave with other people, someone in the crowd shouts with a strong Shanghai stock market accent: "Comrade Xiaozhuang, you just said that this leafless fan is just an attempt to use aviation technology in civilian products. Is there any other similar product?"

As soon as this remark came out, the crowd who was about to leave unconsciously stopped for a while, and Zhuang Jianye immediately replied with a smile: "the old comrade just asked me a good question. Yes, the leafless fan is just a small attempt of civil aviation power technology of our take-off factory, and our real new product is it..."

As he said that, Zhuang Jianye pulled off a military green tablecloth beside him, and a strange thing more than half a person's height suddenly appeared in front of everyone's eyes. Seeing this, a gray haired old man in the front row immediately opened his eyes and exclaimed: "this is Medical gas turbine
