God of learning, he always wants to break my glasses

What Qin Yang used to make the simulated "engine" was a new type of special soil specially provided by the organizing committee.

The material looks a bit like plasticine, it can be kneaded by anyone, and the hardness can be controlled according to the amount of water.As long as it is dried for 1-2 hours after the production is completed, it can be completely hardened, and the preservation time can reach about a week.

"Team leader, our side will be ready soon!" Shi Jiefei glanced at his watch, there were still 10 minutes before the deadline.

Jian Jiang put the fairing on the top of the rocket: "The structural system of 'Gouliang No. [-]' has been fabricated and assembled."

Press the switch, and the light strip installed inside the rocket body will light up at the same time, and the light will pass through the light cardboard to the outside.

The entire rocket body seems to have become translucent, with the internal structure looming.

The primary and secondary combustion agent tanks, the primary and secondary oxidant tanks are hidden under a huge aluminum skin.

"'Dog Food No. [-]', the power part is completed." Dun Nuo continued.

Qin Yang rubbed the mud off his hands, and placed the finished engine model on the wooden table.

Like holding a birthday cake, he carefully carried the wooden platform and walked in front of the big guy.

The whole classroom was in chaos.

Scrapped cardboard materials are everywhere, glue sticks, nails, 502 can be seen everywhere, and there are several plastic scissors on the ground.

Needless to say, the tin scissors were casually thrown on the desk behind the door, and the deterrent effect was quite strong.

In addition, there are various scrap parts scattered on the ground.It is worth mentioning that, no matter what Qin Yang touched or sat on, none of them survived.

The small corner under the air conditioner is where he sits most often. After the thin aluminum plates and iron sheets are served by sharp iron scissors, long strips and finely divided dross are scattered randomly.

Several buckets of water were placed on the ground by the window, and the special soil splashed out was very eye-catching under the white walls of the classroom.

The floor has almost become a small farming land. Dunno reasonably suspects that throwing some bean sprouts might grow.

In a nutshell: a mess.

"The water is a little too much, it's easy to collapse." Qin Yang carefully placed the engine on the table, then heaved a sigh of relief, clapped his hands, and dropped pieces of caked mud.

Shi Jiefei leaned over to take a closer look.

The entire engine is cone-like, with circles of corrugations on the outside.

The "nozzle pipe" of the engine is a standard cone. At the same time, the pump turbine unit composed of two pumps is very delicate, and some of the details are very well grasped.

The overall size ratio is basically suitable for their 2.3-meter-high rocket model.

He was stunned: "Brother Qin, do you still have this skill?"

Aside from other things, how did such a huge guy like a bamboo shoot make this standard shape without a drawing machine[1]?

The corner of Qin Yang's mouth curled slightly: "Look inside."

"Inside?" Shi Jiefei probed in, "It's pitch black and nothing is there?"

Jian Jiang turned on the flashlight of his mobile phone and gave it to him, and he looked at it again: "What is the circle around the inner wall??"

Qin Yang blew on the broken hair in front of his forehead, and said lightly: "10:1 aluminum plate."

Shi Jiefei: "What? There are many aluminum plates!"

Dun Nuo patted the rocket body, and looked at Qin Yang indifferently but sharply: "Otherwise, why do you think he is so nervous about the aluminum plate? The rocket body here needs to be used, and the engine is also needed there."

"That's why you can't make mistakes." Dun Nuo took out a few tissues and stuffed them into Qin Yang's hands, "Go wash?"

"No need." Qin Yang wiped it casually with a paper towel, and then returned it to Dun Nuo without any psychological burden, "I'll have to move it later, so you don't need to wash it again."

Shi Jiefei immediately turned into a little fanboy, with a pair of star eyes eagerly pulling beside Qin Yang, and said quickly like a string of cannonballs: "Brother Qin! You are my real brother! How did you make such a detailed engine model?" ? Have you really built a rocket? What are these two little things used for? Why are the upper and lower parts of the engine separated?"

Qin Yang didn't rest much, his eyes were dark circles, and his eyelids drooped listlessly.

But he was not as cold as usual, instead he explained patiently: "I learned it before and saw some design drawings. These two are turbine units, which increase the thrust. The upper part is the combustion chamber, and the lower part is the nozzle. .”

He bent down, pointed at the simple engine model he made by himself, and said slowly: "The fuel and oxidant are ignited in the pre-combustion chamber, which drives the turbine to rotate, and then drives the pump to rotate, and then pumps the fuel and oxidant into the combustion chamber. , and eventually thrust. That's about it."

Shi Jiefei followed his guidance to learn the principle of the engine.

After listening to it, I was silent for a long time, and then applauded slowly one after another, shaking my head and admiring: "Brother Qin, you are awesome, you are strong, really. If anyone laughs at you in the future, you don't need to do it, I will call you back. "

Qin Yang blushed black, black turned green, and smiled without any sincerity: "Thank you, you're welcome."

Jian Jiang carried his cub back speechlessly, Gao Leng said: "This guy has never seen anything in the world, it's embarrassing, I'm sorry."

Then he turned his head and pointed at Shi Jiefei by the collar: "Idiot! You are the only one who still fights with others, don't be ashamed!"

Shi Jiefei grabbed his lapel and said fiercely: "Sibaimu, if I say hit him back, I'll hit him. You won't help me fight back!"

Qin Yang's face darkened again.

Also paralyzed.

Dun Nuo poured him a glass of water: "Drink some water, your lips are dry."

When I don’t know, I don’t feel anything at all. Once I am stimulated by some kind of information from the outside world, I feel discomfort in my senses immediately.

Qin Yang licked his lips and almost drank a bottle of water in one gulp.He wiped off the water stains around his mouth, his voice was a little hoarse: "Thanks."

Dun Nuo leaned on the table: "You did a great job, it really is my roommate."

"Don't be shameless, what's the matter with you." Qin Yang sneered, raised his panda eyes that were full of scum, and cocked his tail in a low-key manner, "At the critical moment, I have to rely on you." .”

Deng Nuole praised his stinky feet, and teased: "Okay, knowing that you are the best, and my brother is the best, we are willing to bow down."

"Do you still have the face? Have you forgotten how old you are just because others don't know?" Qin Yang returned the water bottle to him, and said disgustedly, "Who are you calling, old man."

There are only a few hours of sleep at night, and I have been working with high concentration for a long time.

Qin Yang is physically tired now, but his spirit is more active than ever, even excited.

Dunno could feel it.

"Nurture." He called out.

Qin Yang's head was throbbing, but his heart seemed to be blown by a gust of wind. He pursed his lips: "If you have something to say, why are you yelling?"

He thought he understood Dun Nuo fairly well, after all, whether it was the former, the latter, or the hypocrisy and sincerity, he had seen it all.

However, in this Newton Cup competition, even he could feel that his various performances were full of loopholes, and it seemed that he was not the same person with a big difference in state before and after.

He is as dull as Jeffrey Shi, he has only known him for a few days, and he can still see something is wrong without knowing him at all. How can a clear-eyed person like Dun Nuo not be able to see it?

He didn't believe it.

But Dunno never asked.

Why did you win the national award once, but your mid-term exam results are so poor?Why is it so difficult to concentrate and fail to do the questions?Why is it that basic physics is a mess, but why do people know a lot more about astronomy and celestial bodies than ordinary people?

Why are you so familiar with rockets?

Dun Nuo seemed to know everything, watching him bouncing around.And as if he didn't know anything and didn't care, waiting for him to explain himself.

Holding his water bottle, Dun Nuo gently licked the corners of his mouth: "Go back and treat you to candied haws, ten skewers."

Qin Yang raised his eyebrows: "Conscience found out?"

Dun Nuo had a half-smile: "Yeah, after all, you deserve the most credit for winning the first place. If you're unlucky and meet a pig teammate, I won't be able to keep the first place."

Qin Yang picked his fingers, raised his head, his eyebrows and eyes slightly curved: "Really?"

"Of course it's true." Dun Nuo hooked his neck and leaned closer to his ear and said, "In any case, we have to give credit to God Qin this time. With his own power, he turned the tide and not only saved the team, but also successfully washed himself away charge."

Qin Yang slowly raised his right hand hanging by his side, his lips parted slightly: "You..."

But this still failed to stop someone from being idle: "Qin Yang, who scored 38 points in the mid-term physics exam, came second in solo in the Newton Cup competition, and led the team to win the first place. He successfully counterattacked and became a new classmate God of physics."

Qin Yang: "..."

Forget it, I can't say harsh words, and I don't bother to fight.

They did a little tidying up, and Jian Jiang went to the teacher to borrow a small cart. The four of them pushed the cart and carried the engine, lined up in a row, pushed open the classroom door and set off.

"It's raining too much, I'll hold an umbrella." Dunno went back to the classroom and took an umbrella out.

There is a corridor outside the classroom outside H. Due to the orientation and height, sometimes the rain will float into the room when it is heavy.

The place to submit the competition model is the two classrooms on the first floor. There are no stairs, so you have to move it down.

"Big guys are not afraid of water, Nuo Shen, you can just block Brother Qin's engine, we are all fine." Shi Jiefei yelled and put the umbrella Dun Nuo gave them into the small cart.

The cart is actually just an iron plate with four wheels and a handrail. It is usually used by the school warehouse to transport goods occasionally.

The "Dogfood No. 2" simulated launch vehicle is 3 meters long, and its height when erected far exceeds the height of a human being.

They didn't weigh it, but Mao estimated it weighed a few dozen catties, not counting the engine.

Jian Jiang was pushing the cart, while Shi Jiefei held down the rocket head which was far beyond the reach of the cart in front to prevent it from falling out.

Dun Nuo held up an umbrella to keep out the rain, and Qin Yang followed behind them, holding the unhardened engine preciously.

Since "Dog Food No. [-]" was too large, four people had to dispatch it, so every classroom passing by had people poking their heads out to watch.

"What's that panning thing outside?"

"It seems to be... a space rocket. Didn't someone draw this?"

"Of course I can tell it's a rocket, but have you ever seen a rocket that big??"

The four-person team, who was about to hand in the model, looked down at their work: because the table was too small and it was not flat when assembled, they deliberately put the cruise ship on the ground to build it.

The cruise ship is high-end and elegant, with fine workmanship and large size. The most commendable and proud thing is that it has [-] guest rooms!

It has a famous name - "Fuxing Cruise Line"

Not only can it meet the needs of passengers, but the speed of the ship is super fast!In order to show its luxury, they also specially added a one-meter-long light strip exchanged at 4:1, which is wrapped around the cruise ship, which is invincible and beautiful.

Among other things, just this volume and this height, it is an absolute instant-killing work—such as the poor little ship of the "Light Speed ​​Black Hole" group in the same classroom.

It is 95 cm long and 40 cm high. It is a super luxurious cruise ship. This model can be sold for at least a few thousand even if it is put on the market.

That thing outside...

No, it must be their eyesight.
