Entertainment: The Movies I Made Can Extract Skills

Chapter 139 As soon as I finished talking about the solid propellant ratio in solid-liquid mixing, a pile of knowledge and principles about solid-liquid mixing engines emerged in my mind.

He turned and walked quickly back to his desk.

I picked up a piece of paper and a pen casually and started to write.

Several professors looked at each other.

What’s wrong?

Could it be that Shen Zhe was inspired?

They leaned forward curiously.

I saw that Shen Zhe had written a lot of things on the drawing paper.

“75% of dinitrogen tetroxide and 25% of nitrogen oxide are used as oxidants, 90% of polymethacrylate and 10% of magnesium powder are used as solid fuels, and the theoretical specific impulse is 2708N·s/kg…… ”

Shen Zhe is counting!

A whole piece of drawing paper was filled with him.

Shen Zhe pulled out another piece of drawing paper.

Calculated on it.

Probably dozens of minutes have passed.

The value is calculated.

“The actual specific impulse is 2453N·s/kg, the diameter of the oxidizer tank is 0.33m, and the diameter of the combustion chamber is 0.25m…”

The further Professor Sun read it, the more incredible it became.

Are these all relevant values ​​for a solid-liquid hybrid engine? !

“What is the specific impulse of the engine we built before?” one of the professors asked.

“2355 N·sec/kg, medium energy.” Professor Sun said.

“Is Shen Zhe going to build high energy as soon as he comes up?! This is more than 2450 per kilogram per second!”

Everyone took a deep breath.

Do you want to do the best?

“thrust……”

“300s?!”

Everyone was stunned.

Look at Shen Zhe’s calculation formula and the final result.

This thrust really surprised them.

At this point they had forgotten to draw solid engine drawings.

If this is the thrust of the solid-liquid hybrid engine.

What kind of solid did they make!

“Solid engines have about 200 thrust, and liquid engines only have about 200 thrust.”! ”

“this……”

Everyone was dumbfounded.

Why is the solid-liquid mixing value designed by Shen Zhe so amazing!

Compared with solid-liquid mixing.

Regardless of whether it is a solid engine or a liquid engine, it seems that the workload is much greater!

The calculation alone is very complicated!

Slowly, Shen Zhe’s drawing paper has drawn a lot.

The paper on hand was also slowly piled up.

Soon, the sun slowly moved to the south.

It’s noon.

A few hours in the morning.

Shen Zhe hasn’t spoken since sitting down and drawing drawings.

Professor Sun glanced at the time, and then said, “Mr. Shen, take a break, it’s time to eat.”

Shen Zhe still lowered his head, touching the paper with the pen in his hand, making a slurping sound.

The sound never stopped.

“Mr. Shen?”

Sudden.

The voice stopped.

Shen Zhe looked up at Professor Sun, “What’s the matter?”

Professor Sun smiled and looked at Shen Zhe with some admiration.

“It’s noon, it’s time to eat. Humans are iron and rice is steel, especially for us scientific researchers. Three meals a day must not be small. If you eat irregularly and work for a long time, you will easily faint. ”

Several professors also looked at Shen Zhe in admiration.

Persuaded, “Walk around, put down the pen in your hand, and go to dinner together.”

As a young man, Shen Zhe is also the son of the richest man.

Can devote so much attention to scientific research.

Let alone whether the final solid-liquid hybrid engine can be developed.

First of all, his spirit is very difficult.

Once, children’s dream was to be scientists, teachers, astronauts, doctors…

However, the dream of many children now is to be a celebrity, an internet celebrity…

Seeing Shen Zhe’s young age, it takes three hours to sit on a stool.

I have been calculating, my hands have never stopped, but my butt has never moved.

This spirit is worthy of praise.

Shen Zhe touched his stomach.

“Not to mention that I forgot, I’m really hungry.”

“Then go! Let’s eat together!”

“Go and go!”

Several people walked out of the office and walked towards the cafeteria.

At this time, several professors saw Shen Zhe’s drawings and felt a little relieved.

Although not necessarily the final result.

However, compared to just saying nothing.

They still admire Shen Zhe’s talk-and-go spirit.

If you don’t try, how can you know if you can succeed in the end?

At this time they are holding the mentality of giving it a try.

However, this morning, they didn’t help much.

Professor Sun feels a bit idle and wants to continue drawing solid rocket motors.

But this is completely separated from Shen Zhe’s current job.

If the solid-liquid hybrid rocket engine is really made.

What solid engine did he develop!

Therefore, he plans to draw drawings with Shen Zhe in the afternoon.

Several people walked towards the cafeteria.

Professor Sun asked, “¨ˇMr. Shen, is there any work that can be assigned to us?”

Shen Zhe thought for a while, “The room is a bit messy, and the open space is a bit insufficient. Please clean up first. It is best to clean up all the drawings except for the solid-liquid hybrid engine.”

Shen Zhe’s words surprised everyone.

What does this mean is that we will concentrate on developing solid-liquid hybrid rocket engines in the future?

Put everything away?

How many drawings can be drawn!

Although the solid-liquid hybrid engine is very complicated, after all, their office is the largest office in the entire building.

70 square meters!

Can’t fit a solid-liquid engine drawing in such a big office?

Even if it is a solid engine and a liquid engine, the drawings of the two engines are placed in their office, as long as they are organized, they can still be opened.

Does a solid-liquid hybrid engine need to draw so many drawings?

They have some doubts.

After all, I haven’t touched it.

So they can only nod their heads with a dubious mindset.

“(Wang Ma Zhao) Is there any job then?” Professor Sun then asked.

At this time they had already walked to the cafeteria.

Shen Zhe took the dinner plate.

I randomly picked up a few dishes that looked good and placed them on the plate.

He picked it up, and said, “The other thing is that you don’t disturb me at ordinary times. When I finish drawing the drawings, you need to prepare the materials.”

Several professors were stunned.

They are research professors who have been working for decades!

Just do some chores when working with Shen Zhe? !

To be honest, no one wants to put it on anyone.

Although it is easy.

But they also want to contribute to the country!

“Are there any serious jobs?” Professor Sun asked further.

“Then if you can calculate the total vacuum impulse, vacuum specific impulse, combustion time, oxidant quality, and cost of the solid-liquid hybrid engine, it will save me a lot of time.”

Professors: “……”.
