moving city, ark

The sound of machinery running rang out in the workshop.

The indicator lights on various parts of the thruster light up successively along the way, and after reaching the tail end of the thruster, a faint blue light gradually emerges from the depths of the thruster nozzle.

The coil at the end of the nozzle was quickly filled with blue light, and then, the azure blue tail flame burst out like a light blade with the buzzing sound of a sudden connection.

"Om-"

The propeller on the assembly platform was firmly bound in place, and various data on the screen beside it were jumping rapidly.

"Tsk tsk tsk, 124km/s, this jet flow speed is too exaggerated."

Nian stood in front of the screen and sighed in amazement.

In fact, the jet velocity can be roughly equal to the specific impulse, because the definition of specific impulse itself is 'the impulse produced by the propellant per unit weight (force) of the engine'.

Ordinary chemical working fluid propellers, taking an F1 liquid oxygen kerosene engine as an example, the jet velocity is about 2596m/s, which is about 2.6km/s.

The electric propulsion engine has an unparalleled advantage in the specific impulse, and in the hands of Luo Yi, it has been brought into full play.

However, the specific impulse of the electric propulsion engine originally occupies an advantage that is difficult to compare with the chemical engine, so it has attracted many scientists to focus on it, but the key point that has always restricted the electric propulsion engine is not here.

"Huh? Don't you read it?"

Nian, who was about to continue studying the data on the screen, suddenly noticed that Luo Yi on the side actually ran to the other side to pour a glass of water and drank leisurely.

"It's useless."

Luo Yi, who had been holding the water glass in his hand, raised his other finger and pointed to his temple, the corners of his mouth slightly curled up, "There is already an answer here."

"Tsk, you know how to pretend to be handsome, didn't you plan it from the beginning?"

Nian pouted.

Regardless of Luo Yi's helpless appearance, he turned his gaze and continued to look at the screen in front of him.

"The power is only 1000kw, don't be too happy."

In fact, the figure of 1000kw is not small. Most of the power of ordinary electric propulsion engines is only a few kilowatts, and most of them are no more than a dozen kilowatts. would be so pitiful.

But if you want to put this thruster on the spacecraft, 1000kw is definitely not enough.

"Since this is the case, then you can just watch over here and let me know when the final test results come out. I'll take a shower first, um, and get some food by the way."

Putting down the cup in his hand, Luo Yi, who turned around, left a back view very coolly, while waving his hands, he walked straight to the door of the workshop.

"what?"

Whose thing is this?

She glanced at the ever-changing hyper-complex graph on the other side of the screen.

Hell, who can see this kind of thing!

Anyway, she is a god, and she thinks that her calculation ability is not bad, but compared with that guy over there, she wants to ask who is the monster.

'What kind of real human beings are just bullshit. '

She couldn't help complaining in her heart.

"Hey! The promised celebration banquet! Set up the hot pot and wait for me to come out, don't steal it!"

After all, it is the result of my own hard work, and someone must be here to watch.

She has always been very concerned about her own works, not to mention that each piece is like her own child, but she can't just abandon it, it's too pitiful.

She can't be as ruthless and ungrateful as Luo Yi

Obviously the Lord is not worried...

I'm so angry!

I always feel that what is going on is being pulled back.

Nian's tail swung rapidly behind him.

"Where are there so many demands, hurry up!"

Luo Yi's voice came from outside the door.

"Hey!"

……

Because the last step of the project was already planned for this afternoon, Luo Yi had already greeted his family in advance, and he might have a celebration dinner with his partner in the studio for dinner.

After taking a shower in a relaxed and happy manner, he changed his clothes and set up the hot pot that he had prepared earlier.

Based on the tastes of the two people here, of course, things like mandarin duck pot are completely out of consideration.

Red oil, chili!

Watching the red-dyed butter cubes sink and float in the bubbling red soup, a pleasant feeling arises spontaneously.

He continued to bend over.

Meat, mushrooms, soy products...

A large pile of dishes were taken out of the refrigerator and placed on the vacant table, surrounding the bottom of the pot that had already been foggy in the middle.

"Gollum."

He swallowed slightly, and then said to himself, "Why don't you start it first? Anyway, it should be almost the same over there, and it's okay to be late."

"I heard it all!"

The year appeared!

"The test is over?"

he asked strangely.

It shouldn't be so fast.

"Anyway, it's been stable for so long, even you, a man, have run away, why should I stay there alone?"

lone vacancy...

He grinned, ignored the ambiguity and bad taste in the other party's words, and continued to ask expressionlessly.

"How much power did you get when you came out?"

"It's more than 40000, and the condition can't be better. It is indeed my masterpiece."

Luo Yi nodded slightly.

At 40000 kilowatts, it has almost reached the level of most rocket chemical engines, and this figure is obviously not the upper limit of their achievements.

On top of this, with the same power, the final thrust generated by the specific impulse of the electric propulsion engine is not comparable to that of the chemical engine.

More than 90% of the mass of the rocket is occupied by fuel. After reducing most of the mass and volume, the final spacecraft may be the size of an ordinary aircraft.

In other words, even if the test is not over yet, but at this time

They can already declare victory for both.

In other words, the celebration banquet for the two of them officially began.

The ingredients are put into the pot, the wine is poured into the cup, and the warm atmosphere immediately fills the air with the wafting fragrance.

"Come, come, punch!"

Nian, who seemed to be eating happily, stepped on the chair, rolled up his sleeves, and gestured to him, with the corners of his eyes raised up, showing a provocative look, "You don't know, do you?"

"Of course I will,"

He couldn't help complaining, "But are we good brothers who talk and drink?"

"Hey? It's up to you~ My dear best friend~"

第 665

Chapter 370 Eight Loss of Marriage Qualification

This hot pot meal lasted for more than two hours.

The originally good studio is now full of the smell of hot pot and wine.

Several quaint wine jars were piled up in a mess on the tabletop with no one around.

Of the two people in the room, one had extraordinary physique, and the other was completely inhuman, drinking wine was like pouring water.

And of course hot pot can't be paired with red wine. This guy Nian didn't know where he got it, which is said to be a treasured white wine. The feeling of the wine rolling down his throat is more stinging than the temperature of the hot pot.

"Huh - lie down for me."

He shook his head, and slid down the back of the sofa, resting on Nian's thighs that were always uncovered and full of presence.

My head is a little dizzy.

"You can't do it?"

A teasing voice came from above.

"Tsk, who's been through the intestines with wine and meat like you. And your wine shouldn't be ordinary, right?"

He scratched his hair and moved his head and body slightly to find a more comfortable position.

The warm temperature and elastic touch make people unconsciously want to close their eyes and bury their face in the smooth belly beside them.

He had already wiped his mouth, so he didn't have to worry about any strange troubles.

"That is,"

The answer from [-] was passed on, "Ordinary wine can't bear the word 'treasure'. Back then, these wines were also obtained from those big gangs for appreciation based on their own face, and they have been thrown in my pocket. You have to thank me for keeping it in a small space until today."

"Hey, I think you are relying on your thick skin."

He couldn't help laughing, trying to maintain the gap between his eyelids.

"I was considered a respectable person back then, okay! There are so many people who come to me to make magical weapons, and I'm so annoyed, and I'm tired of staying in one place, so I decided to start wandering around."

Nian boasted loudly.

Of course, with Nian's abilities, there might indeed be some credibility in this.

But bragging is always more effective if it is exaggerated on the basis of reality.As for the bragging part, it is debatable.

But he didn't care, instead he continued following Nian's words:

"Then if I bear your name, Teacher Nian, will I be able to get out of Dayan with an acre of land?"

Although the origin of Teacher Nian's name seems a bit unserious.

"That's the old calendar from many years ago. If you go there now, maybe you can find a few people who know me."

"and,"

It seemed that he thought of going with him, and his waist was poked by something soon.

Very familiar feeling.

"Isn't it too embarrassing to pull out a great Kaishan disciple who has learned all kinds of obscene skills?"

"Don't move around—"

He grumbled and reached out to grab the palm of his waist.

This guy is messing around again.

And this time, because of the strength of alcohol, his heartbeat seemed to be two beats faster.

But speaking of...

Ok……

"Hey?!"

A stunned voice came over, and while he was gleefully laughing, he was almost thrown off the sofa.

He was so frightened that he quickly threw away the palm in his hand, and crawled back with Nian's thigh.

"Is it necessary to react so much?"

Thanks to this blessing, his vision suddenly became much clearer.
