"This ...... This...... This ......"

Meng Jianglin watched the leaders who came towards their booth, turned around and ran to the booth of Tengfei Factory, and his mouth was open for a long time without coming for a reason.

There's no way, he still hasn't figured out how the circle of Tengfei Factory came out, didn't it blow with his mouth?

Not only Meng Jianglin, but also the leaders who surrounded the booth of Tengfei Factory were more curious, not to mention whether the wind blowing was comfortable, the key was where the wind came from.

You must know that the basin-like circle is really empty, there is no fan turning, and there is actually wind constantly gushing out, which simply refreshes the three views of these people.

"Ladies and gentlemen, this W-8 bladeless fan in front of us is another successful attempt in civilian products after our Tengfei factory digests and absorbs the latest aviation power technology. ”

As soon as these words came out, the people who were still surrounding the bladeless fan were immediately attracted by Zhuang Jianye's words, no way, this sound is particularly lofty, the latest aviation power technology This sentence makes people reverie, combined with the incomprehensible bladeless fan in front of them, immediately attracted the eyes of the people around them.

Zhuang Jianye wanted this effect, naturally he was not stage frightened, and gestured to Master Ju, who was a little stunned by the crowd of leaders: "Then take out our model." ”

"Ah~~Oh!"

Master Ju subconsciously responded, mechanically squatted down, picked up the model placed under the display case, and unwrapped 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 him.

The people around me saw the novelty, and they took the real thing for the exhibition and sale of electric fans, and it was the first time I saw someone using a model, but I was even more curious.

Zhuang Jianye didn't let everyone'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 everyone: "Everyone, please see, this ring is an air supply channel, which looks not complicated, but it is actually the crystallization of the latest aero engine cooling technology, that is, the ejector technology." ”

"Little comrade, the ejector technology is not simple, especially on the small aero engine used for missiles, it is a very effective cooling mechanism, but what do I think, this thing of yours is not the same as the ejector I have seen?"

As soon as Zhuang Jianye's words fell, a middle-aged man with glasses and polite quality frowned and asked, and the people around him also felt that what the middle-aged man said was very reasonable, and nodded subconsciously.

There is no way, although these people are all cadres with positions in various ministries and commissions, a large part of them have worked in the first-line factories of the national defense industry in their early years, and even served as the core or leader of important technical projects.

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

But no matter how much ink they had in their stomachs, they couldn't stand such a cheeky Zhuang Jianye, so I saw him touch the fan base, open a lid, take out a delicate small motor from it, and then hold it in the palm of his hand and hand it to everyone.

The middle-aged man who asked the question just now first squinted his eyes, then stroked his glasses, and a trace of surprise flashed in his eyes unconsciously, and asked, "Is this ...... Turbofan power plant?"

Other knowledgeable people also looked at Zhuang Jianye, no way, it was really the little thing in his hand how it looked like a condensed 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 cooling principle of the small jet-powered ejector for missiles, and use the absorbed motor to absorb the air from the bottom into the closed ring, and at the same time spray out the wind flow, due to the principle of the ejection effect, the natural and fresh wind will continue to be sent to you through this ring." ”

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

Widely used in aviation, ships and other fields, Zhuang Jianye said that the ejector is an application of the ejection effect, because the small jet power device used in missiles is generally well sealed, the traditional air cooling can not meet its needs.

As a result, an ejector using the principle of ejection appeared, which drove the surrounding air flow through the ejector to cool the engine itself through its own high-speed airflow.

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) fighter, that is, a device with an ejection effect is installed in the tail nozzle of the aircraft to cool the high-temperature gas with high-speed flowing cold air (J-20 has applications).

As for navigation, not to mention, the pump and push device behind the submarine is a typical application model of the ejection effect.

There are many experts in this area among the people around, even if they are not experts, they will understand it by the senior people next to them, so after listening to Zhuang Jianye's introduction, curious people suddenly realized that the so-called bladeless fan is not really bladeless, but just using the rough aero engine principle to do some structural innovations.

Once the secret is revealed, the interest is gone, just like magic, and all kinds of magic are amazing when performing, but as long as the doorway inside is made public, it will be ridiculed with scorn.

It's the same with these people around the Tengfei Factory, they just gathered around because of curiosity, but now that the mystery has been revealed, there is nothing new to say, so naturally they have become less interested.

As for the peers who watched the excitement from the periphery, they laughed even more, thinking that Zhuang Jianye's kid was really a big treasure from God.

Such a good thing, just make a simple function introduction, this baby is actually in place in one step, the structure, principle and technical characteristics inside are all lifted off, the leaders do not know what mood they have, anyway, they have gained a lot.

So there are many people who are ready to go back to privately engage in imitation, among which Baba came to see the lively Meng Jianglin, and before he finished listening, he asked the office director next to him: "Have you written it down?"

The chief of staff nodded: "Write it down." As he spoke, he handed the small notebook he recorded to Meng Jianglin

"Wait until you go back, study and study it well, hey, Zhuang Jianye is in a hurry to go to the doctor, such a good thing is public, hehe, if you don't have to blind him this mind." Meng Jianglin took it and flipped it over, and his mouth immediately grinned to the root of his ears.

Seeing that there was no secret on the Tengfei Factory, and when he was about to disperse with others, he heard someone in the crowd shouting in a thick Shanghai accent: "Comrade Xiaozhuang, you just said that this bladeless fan is just an attempt by you to use aviation technology in civilian products, is there any other similar product?"

As soon as these words came out, the crowd who was about to leave subconsciously paused, and Zhuang Jianye immediately responded with a smile: "The old comrade just now asked well, yes, the bladeless fan is just a small attempt to civilize the aviation power technology of our Tengfei Factory, and our real new product is its ......."

As he spoke, Zhuang Jianye tore off a military green tablecloth beside him, and a strange thing more than half a person tall appeared in front of everyone's eyes, and an old man with gray hair in the front row immediately widened his eyes when he saw this, and then exclaimed: "This is...... Medical gas turbines?"
