    "Thisthisthis"

    Meng Jianglin watched helplessly as the leader came towards their booth. He turned around and ran to the Tengfei Factory booth. He opened his mouth for a long time but didn't come up with any explanation.

    No way, he still hasn¡¯t figured out how the wind came out of the circle in Tengfei Factory. Isn¡¯t it blowing with his mouth?

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

    You must know that the basin-like circle is really empty inside. There is no fan rotating, but there is wind constantly pouring out. It simply refreshes these people's three views.

    "Dear leaders, the W-8 bladeless fan in front of you is another successful attempt at civilian products after our Tengfei Factory digested and absorbed the latest aviation power technology."

    As soon as these words came out, everyone who was still marveling at the bladeless fan was immediately attracted by Zhuang Jianye's words. There was no way, these words sounded very high-end, and the latest aviation power technology sounded very impressive.  Combined with his reverie and the puzzling bladeless fan in front of him, he immediately attracted the attention of all the people around him.

    Zhuang Jianye wanted this effect. Naturally, he was not afraid of stage fright. He motioned to Master Ju who was in a daze as a group of leaders were watching: "Then take out our model."

    "Ah~~oh!"

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

    ???????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????: The electric fans are used in real-life exhibitions and sales. This is the first time I have seen someone using a model, but I am even more curious because of this.

    Zhuang Jianye didn't let everyone's curiosity last too long, he touched the circle of the model, immediately removed a section, pointed to the cross section inside and said to everyone: "Look, everyone, this ring is an air supply channel.  , it doesn¡¯t look complicated, but it is actually the crystallization of the latest aero-engine cooling technology, which is ejector technology.¡±

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

    As soon as Zhuang Jianye finished speaking, a polite middle-aged man wearing glasses frowned and asked. People around him felt that what this middle-aged man said made sense and nodded subconsciously.

    No way, although these people are all cadres with positions in various ministries and commissions, most of them worked in front-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 is impossible to fool them with some specious concepts, because there is 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 up to such a shameless Zhuang Jianye. He touched the base of the fan, took off a cover, took out a delicate small motor from it, and then held it in his hand and handed it to him.  In front of everyone.

    The middle-aged man who asked just now squinted his eyes first, then stroked his glasses, a trace of surprise flashed unconsciously in his eyes, and asked: "Is this a turbofan power device?"

    Other knowledgeable people also looked at Zhuang Jianye in unison. They had no choice but to think that the little thing in their hands looked like a condensed turbofan engine.

    Zhuang Jianye smiled and shook his head: "We used the turbofan device of the turbofan engine to build an innovative motor, and then used the cooling principle of the missile's small jet-powered ejector to absorb the air absorbed from the bottom of the motor.  Entering the closed ring, when the wind is sprayed out, due to the principle of the radiating effect, the natural and fresh wind will be continuously sent to you through the ring."

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

    It is widely used in aviation, shipbuilding and other fields. The ejector mentioned by Zhuang Jianye before is an application of the ejector effect. Since the small jet power devices used for missiles generally have better airtightness, traditional air cooling cannot meet their requirements.  need.

    So the ejector using the ejector principle appeared. Through its own high-speed airflow, it drives the surrounding airflow through the ejector to cool the engine itself.

    In addition, in the new century, the ejector effect has also been applied to the infrared stealth body of fourth-generation (also called fifth-generation) fighter aircraft. That is, a device with ejector effect is installed on the tail nozzle of the aircraft to  The high-speed flowing cold air cools down the high-temperature gas (J-20 has application).

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

    There are many experts in this field among the people around. Even if they are not experts, they will understand it after being popularized by the senior people next to them. So after hearing Zhuang Jianye's introduction, the curious people suddenly realized that the so-called bladeless fans are not really bladeless, they are just fan blades.  It's just using superficial aero-engine principles to make some structural innovations.

    Once the secret is revealed, the interest will disappear. It is like magic. During the performance, all kinds of magic are amazing, but as long as the secret inside is made public, it will be scorned and ridiculed.

    The same goes for the people surrounding Tengfei Factory. They gathered around just out of curiosity, but now that the answer to the mystery has been revealed, there is nothing novel at all, so they naturally become less interested.

    As for the colleagues who were watching the excitement from the outside, they were all bursting with laughter. They felt that this boy Zhuang Jianye was really a great treasure sent by God.

    It's such a good thing, just give a simple function introduction. This baby actually gets it right in one step, and completely breaks down the structure, principles and technical features inside. They don't know how the leaders are feeling. Anyway, they are here.  Achieve a lot.

    So it can be said that there are many people who are preparing to go back and make imitations in private. Among them is Meng Jianglin, who came to watch the fun. Before he finished listening, he asked the office director next to him: "Did you write it down?"

    The office director nodded: "Write it down." After saying that, he handed Meng Jianglin the small notebook he kept.

    "Wait and study it carefully when we get back. Oh, Zhuang Jianye is in a hurry and seeks medical treatment. Such a good thing is made public, haha, if only his efforts would not be in vain." Meng Jianglin took it over and turned it over, grinning immediately from ear to ear.  Root.

    Seeing that there were no secrets here at Tengfei Factory, and just as he was about to disperse with the others, he heard someone in the crowd shouting with a strong Shanghainese accent: "Comrade Xiaozhuang, you just said that this bladeless fan is just for you."  This is an attempt to use aviation technology in civilian products. Are there other similar products?"

    As soon as these words came out, the crowd who were about to leave subconsciously paused. Zhuang Jianye immediately responded with a smile: "The old comrade just asked a good question. Yes, the bladeless fan is just the civilian application of our Tengfei Factory's aviation power technology.  A small attempt, and our real new product is it"

    As he spoke, Zhuang Jianye pulled off a military green tablecloth beside him, and a strange thing about half a person tall suddenly appeared in front of everyone. An old man with gray hair in the front row immediately opened his eyes wide when he saw this, and then exclaimed.  Speak out: "This is a medical gas turbine?"
