Different from the gloomy clouds and fog on Yang Wenzheng's side, in a temporarily prepared warehouse, Feng Tianyou, Wang Ziyang, and Lu Yeqian were circling around Lao Yan's "Qinshan-1" engine, and the atmosphere was extremely relaxed and happy.

Feng Tianyou and several people were full of praise for Lao Yan's engine and praised it again and again.

"Director Yan's engine is really breathtaking, whether it is the design idea or the implementation method, there are many things worth learning. "Feng Tianyou said.

"That's right, this kind of engine, I'm afraid we can't design it with Lazy God Technology, Uncle Yan, you're awesome!" Prince Yang didn't hesitate to praise himself.

"Well, this engine can indeed be opened, if you dig deeper, you can develop our own new engine on this engine system, to make up for many shortcomings in China. Lu Yeqian nodded again and again, speaking in the style of a person in the system.

Lao Chu next to him and a leader of the general assembly all lit up when they listened.

If it weren't for these big names of Lazy God Technology praising Boss Yan, I'm afraid they wouldn't have been able to see the benefits of this engine.

Feng Tianyou's eyes rolled and said, "I heard that you want to cut this engine? ”

"Sell it to you?" Hearing that these people from Lazy God Technology wanted to buy it, Lao Chu was stunned for a moment, and before he could speak, the leader of the general assembly next to him had already spoken: "Sell? No, no, no, that's not good! This is an important asset of the country!"

"Don't you want to sell it? Don't you want to cut down the mothballed engine? This kind of thing, the technology is improving all the time, if it is mothballed for three or five years, it will be worthless, you also know that the technology of our lazy god technology is developing very fast, and this kind of engine will be useless to us immediately. In this way, I will give 200 million!"

"Dollars?"

"We are Chinese, of course it is RMB. "Feng Tianyou said.

"200 million, Lao Feng, are you crazy?" Prince Yang grabbed Feng Tianyou and said, "You spend 200 million to buy this ......"

"200 million can help us save a lot of time, and it is worth it. Feng Tianyou said, he swept his eyes and looked at the leader of the general assembly: "How about it, sell it or not?"

"No, no, no, no!" The leader was really anxious, and shook his head again and again, "We have spent more than 10 years of manpower and material resources to develop, and we will sell it for 200 million.

Lao Yan listened to it with a wry smile frequently.

In the same way, just now he said a basket, or it is inevitable that the "Qinshan-1" will be cut down, saving money to give in to the fate of "Changkong No. 1", and now the wind and God bless them, you and me, three or two sentences, this set of Qinshan, which is about to be cut down, has become an important national asset, to make up for the domestic gap.

It seems that the idea of the final assembly has changed a bit, and it is no longer inclined to completely close the research group.

Lao Yan saw Feng Tianyou secretly raise his eyebrows for him, and immediately understood in his heart that this was Feng Tianyou personally going to the sea to carry a sedan chair for him.

Everyone carries the sedan chair, but this sedan chair is not ordinary.

Lao Chu next to him also smiled helplessly.

Comrade Chunkui really knows Feng Tianyou and these people too well, and when you look at them pouting their butts, you will know ...... What's that.

What 200 million yuan to buy technology? Lazy God Technology really does not lack 200 million, but the money is not spent like this, what do they want this kind of technology for? Go back to the table?

But as soon as they say this, no matter how much this technology is originally worth, it can be bought by the people of Lazy God Technology for 200 million, so how much is this technology worth to others?

On the contrary, it was the leader of the general assembly, but he was fooled by a few young people, in fact, he didn't blame him, first, he was not from a technical background, and he was not on the front line, after all, he was separated by a layer, and he couldn't see it really. Second, the aura on the body of Lazy God Technology is too bright, so bright that it blinds people's eyes, in terms of technology, the words that come out are simply shining gold, 24K pure gold! Change places, or go back to ponder, I'm afraid you can react, but at this moment, he is still dizzy and can't extricate himself.

Declined the proposal of Lazy God Technology to buy technology, and the director of the final assembly said: "Qinshan-1 is indeed the engine model we focus on developing, I wonder if Lazy God Technology can give some technical support in this regard?"

"No problem!" Feng Tianyou patted his chest, "Let's not talk about our Lazy God Technology and Lazy God Shipyard, which have been old neighbors for many years with our seven institutes." Just talking about our old friendship, can you say a word?"

"Really?" Feng Tianyou said, and the researchers next to him immediately became excited, and hurriedly rushed up, standing beside Feng Tianyou and asking questions, mostly engine-related questions.

Feng Tianyou doesn't hide it, he will answer if he will, and if he can't, he will say that he can't answer for the time being, go back to check the information and then say, the atmosphere on both sides can be called warm.

As he spoke, the topic was led to the Silence again, and a voice sounded from the side: "May I ask what principle does the Silence's thrusters use?"

"Oh, this, it's very simple, in order to make the Silence fly, we used multiple propulsion, the space on the Silence is relatively large, we used a rocket engine combined with ion propulsion. "Feng Tianyou said.

Now that there are so many people and chaos, Feng Tianyou didn't notice it at all, and the person who asked this question was actually Yang Wenzheng, who came back quietly.

Yang Wenzheng quietly hid on the periphery of a group of young researchers, and asked questions with his head drooping.

Even Yang Wenzheng himself didn't expect that he would be able to get an answer.

"Rocket engine?" This answer was beyond the expectations of many people, "combined with ion propulsion?"

This set of techniques is used to propel a ship...... This...... That's too expensive, isn't it?

Not to mention, how can ion propulsion be used in outer space, not in the atmosphere?

"That's right, in fact, a complex and high-end engine like Qinshan-1 can't be built by Lazy God Technology, and the engine structure of the Silence is actually very simple. Feng Tianyou didn't hide his selfishness, "Is there a blackboard?"

"No blackboard, whiteboard okay?" a young researcher hurriedly pushed over a whiteboard.

Feng Tianyou casually drew a schematic diagram on it: "The engine of the Silence is actually like this, and there is a rocket thruster in front of it. ”

Feng Tianyou first drew a rectangle in front: "Everyone knows that the principle of rocket thruster is very simple, that is, just mix the fuel into the combustion chamber and ignite it." The difference is that we added a U-tube in the back, so the Silence, although it has four vents, is actually twin. ”

Twin engines are two engines.

"In this U-shaped tube, we have added a gradient electric field to accelerate the ionized hydrogen and oxygen flame to be ejected, because of the deflection of the electric field, if someone goes to test it, they will find that the two nozzles above and below, the content of positive charge and negative charge is different, and the thrust and attitude can be adjusted by adjusting the electric field. If the speed of the Silence is too fast, there will be lightning in the rear, so you can take a closer look......"

Ignition combustion, electric field control, almost all mechanical devices are completely abandoned, so the engine of the Silence is simple to rudimentary, yes, it's lazy.

But if it wasn't broken, who would have thought that the engine of the Silence would be such a design, leaving everyone stunned.

No wonder the Silence can fly!

After all, the thrust of a rocket engine is much greater than that of a gas turbine.

Yang Wenzheng's body trembled with excitement, and it was really great that he could easily set out the technical background of Lazy God Technology.

Next, there was no need for him to ask, naturally there were excited young researchers to help him ask, and he just needed to record desperately in the back.

"So what about the fuel used by the Silence? How much fuel does it take to propel the Silence?" The thrust of the rocket engine is very strong, but it is also too expensive, for example, the American space shuttle has a take-off weight of 4.5 million pounds, that is, 2,000 tons! It is almost exactly the same weight as the Silence! But everyone has seen that the space shuttle carries a huge outer storage tank, and it is full of fuel! It can be said that the vast majority of the weight of the space shuttle is fuel! And the cost of its launch is ...... $500 million each time!

It burns money every second!

And what about the Silence? I didn't see an external fuel pack, and it took off once when there was nothing to do, and once it flew around the world, although it did not break out of the atmosphere, but in terms of straight-line distance, it was much farther than the powered flight distance of the space shuttle.

What a lot of fuel is used in this!

"Metallic hydrogen! Metallic hydrogen is the best chemical fuel. "Feng Tianyou said.

Everyone opened their mouths, your sister, metal hydrogen!

Burning metal hydrogen as fuel...... Just a dozen grams of something on the black market that can sell for hundreds of millions of dollars? Why don't you die?

Why did you get a rocket engine on the Silence enough to make people complain, and even burn metallic hydrogen?

"The cost of metallic hydrogen is high...... someone next to him said weakly.

"It's not just the high cost of metallic hydrogen...... The cost of liquid hydrogen is also very high...... "It's humane."

"How do you make metallic hydrogen?" suddenly a bright child thought of this question.

"Electrolyzed water, the sea, you are all water!" said Feng Tianyou.

"Electrolyzed water is very expensive, so it consumes ...... electricity"

"Generate your own electricity. Feng Tianyou said as a matter of course.

"How do you generate electricity......

"Burning metal hydrogen to generate electricity, I tell you, metal hydrogen power generation efficiency is high!"

Your sister!

Metallic hydrogen is burned to generate electricity, water is electrolyzed to produce metallic hydrogen, and metallic hydrogen is used to generate electricity...... You perpetual motion machine, you!

Do you have a thermal energy formula?

A group of excited researchers suddenly discovered that this Feng Tianyou Feng had explained his Silence technique for a long time......

In the end, it was the same as the three lines that Nanming wrote to Qingzhong Yang and Lao Chu back then.

How is metallic hydrogen prepared?

1. Fill the container with hydrogen.

2. Pressurize the container to 500,000 atmospheres.

3. Take the metal hydrogen out of the container and isolate the air to maintain the pressure.

The reason is so simple and straightforward.

It's as simple as how to put an elephant in the fridge......

But...... Nima, the concubine can't do it!

Is there no one in the world who can do it well?

And Mr. Nan at least gave a correct answer, okay?

You're just fooling!

Lao Chu was standing next to him, and standing next to him was Lao Yan, who had been squeezed out by the young researcher.

Lao Chu looked at Feng Tianyou's appearance in the crowd, and muttered, "Alas...... What has become of the world...... Such a good child is forced to study badly......"

Lao Yan nodded with emotion.

yes, the kids are learning badly. (To be continued.) )
