Take Off My Aviation Era

, The fastest update to take off the latest chapter of my aviation era!

"This...this...this..."

Meng Jianglin watched the leader approaching their booth, turned around and ran to the booth of the Ascendas Factory. He opened his mouth for a long time without showing up.

No way, he still hasn't figured out how the circle of Tengfei Factory got out of it, isn't it just blowing it with his mouth?

Not only Meng Jianglin, but the leaders who surrounded the booth of the Ascendas Factory were even more curious. Let alone the uncomfortable wind blowing, the key is where the wind comes from.

You must know that the circle like the washbasin is really empty. There is no fan rotating, but the wind is constantly pouring out, which refreshes these people's three views.

"Dear leaders, the W-8 bladeless fan in front of us is another successful attempt in civilian products after our Ascendas plant has digested and absorbed the latest aerodynamic technology."

As soon as the words came out, everyone who was still surrounded by bladeless fans was immediately attracted by Zhuang Jianye's words. There is no way. This words is particularly tall when it sounds. The latest aerodynamic technology is very impressive. Daydreaming, combined with the puzzling leafless fan in front of him, immediately attracted the attention of the people around him.

What Zhuang Jianye wanted was this effect. Naturally, he didn't have stage fright. He motioned to Master Ju, who was a little startled by a crowd of leaders nearby: "Then take out our model."

"Ah~~oh!"

Master Ju subconsciously responded, mechanically squatted down, took the model placed under the showcase, and opened the snakeskin bag wrapped on it, revealing a model that was exactly the same as the bladeless fan that was slowly supplying air next to it.

The people around me saw the novelty, and they all took the real thing in the electric fan exhibition. It was the first time I saw someone using a model, but I was more curious because of this.

Zhuang Jianye didn't let everyone's curiosity last too long, so he touched the circle of the model, and immediately removed a section, pointed to the cross section inside and said to everyone: "Look at everyone, this ring is an air supply channel. It looks uncomplicated, but it is actually the crystallization of the latest aero-engine cooling technology, that is ejector technology."

"Comrade, the ejector technology is not simple, especially the small aero engine used in missiles is a very effective cooling mechanism, but what do I think, your thing is not the same as the ejector I have seen?"

As soon as Zhuang Jianye finished speaking, a well-mannered middle-aged man wearing glasses frowned and asked. People around him also felt that the middle-aged man made sense and nodded subconsciously.

No way. Although these people are cadres with positions in various ministries and commissions, most of them have worked in the first-line factories of national defense and military industry in the early years, and even served as the core or leader of important technical projects.

Therefore, it is impossible to fool them with some specious concepts, because the ink in their stomachs is so much that they can drown people.

But no matter how much ink they had in their stomachs, they couldn’t hold back such a cheeky Zhuang Jianye. He touched the fan base, opened a cover, took out a delicate small motor from it, and then held it in his hand. In front of everyone.

The middle-aged man who asked the question first squinted his eyes, then stroked his glasses, a hint of surprise flashed in his eyes unconsciously, and asked, "This is... a turbofan power unit?"

Other knowledgeable people looked at Zhuang Jianye at the same time, but there was no way, it was how the little thing in his hand looked like a concentrated turbofan engine.

Zhuang Jianye smiled and shook his head: "We use the turbofan device of the turbofan engine to build an innovative motor, and then use the missile’s small jet-powered ejector cooling principle, and use the air absorbed by the absorbed motor from the bottom. Entering the closed circle and blowing out wind currents, due to the principle of the ejection effect, natural and fresh wind will continuously pass through this circle and be sent to you."

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

It is widely used in aviation, shipbuilding and many other fields. The ejector mentioned by Zhuang Jianye is an application of ejection effect. Because the small jet power unit used in missiles is generally airtight, traditional air cooling cannot meet its requirements. need.

So the ejector that uses the ejection principle appears. Through its own high-speed airflow, the surrounding airflow is driven to cool the engine itself through the ejector.

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

As for sailing, not to mention, the pumping device behind the submarine is a typical application model of ejection effect.

There is no shortage of experts in this area among the people around. Even if they are not experts, they will understand it after being popularized by senior people next to them. So after listening to Zhuang Jianye’s introduction, people who are curious suddenly realized that the so-called leafless fans are not really leafless fans. It's just the use of superficial aero engine principles to make some structural innovations.

Once the secret is revealed, there is no interest left. It is like magic. The various magics during the performance are amazing, but as long as the doorway inside is made public, it will be ridiculed and mocked.

The same is true for the people surrounding the Ascendas Factory. They were just surrounded by curiosity, but now the mystery has been debunked. There is nothing novel at all, and naturally they have become lack of interest.

As for the colleagues who watched the excitement from the outside, they were even more emotionally happy, thinking that this kid Zhuang Jianye is really a big treasure given by God.

For such a good thing, a simple function introduction is enough. This baby is actually in place in one step, and the structure, principle and technical characteristics inside are all lifted. They don't know what the leaders feel. Anyway, they are here. Achieve a lot.

So planning to go back and engage in imitations in private can be said to be everywhere. Among them, Baba came to see the lively Meng Jianglin. Before listening to it, he asked the office director beside him: "Have you noted it down?"

The head of the office nodded: "Take it down. UU read www.uukānshu.com" and handed the small notebook he recorded to Meng Jianglin.

"Wait, go back, study and study, oh, Zhuang Jianye is in a hurry to go to the doctor, such a good thing is published, ha ha, if you don't need to blind his mind." Meng Jianglin turned it over and turned it over, his mouth grinned to ears immediately Root.

Looking at Tengfei Factory, there are no secrets. When I was about to be a bird and beast with other people, I heard someone in the crowd shout out in a thick Shanghai accent: "Comrade Xiaozhuang, you just said that this leafless fan is just you An attempt to use aviation technology in civilian products, are there other similar products that fail?"

As soon as these words were about to leave, the crowd subconsciously paused, and Zhuang Jianye immediately responded with a smile: "The old comrade just now asked a good question. Yes, the bladeless fan is just the civilianization of the aviation power technology of our takeoff factory It’s a small attempt, and our real new product is it..."

With that said, Zhuang Jianye tore off a piece of military green tablecloth beside him, and a strange thing half a human height appeared in front of everyone. A gray-haired old man in the front row saw this and opened his eyes wide and exclaimed. Aloud: "This is... a medical gas turbine?"
