What's more, this kind of engine can be produced in our country.

So what else is R&D for?

Wouldn't it be nice to buy a few?

Repeated research and development will be laughed off by others. ”

Everyone nodded when they heard this.

How to say that these people are also experts in the field of rockets.

There are advanced engines not used.

Go back to the old engine.

Isn't this a ridiculous joke?

What's more, rocket engines are disposable products.

It is simply impossible to reuse.

In fact, what Su Han said was unreliable from the beginning.

It's just that Su Han is the boss.

There is no identity of Yin Chenghai here, who would dare to slap the boss in the face.

Su Han said: "Of course I know what Yin Gong said. Actually, I didn't think about using kerosene or liquid hydrogen in the first place. Kerosene is prone to carbon deposits and is highly polluting. Liquid hydrogen is unsafe, leaks easily, the temperature is still high, and the engine structure is complex. If you want to produce a rocket engine that can be reused, you have to get rid of these two propellants. A completely new propellant is used.

Actually, I wanted to use a combination of liquid oxygen and methane. ”

Methane!

Everyone was stunned when they heard this!

Methane is actually natural gas.

Of course you know that.

But the problem is that I haven't heard of any country that now uses methane as a rocket propellant.

The thrust of the first-stage engine is insufficient.

Vacuum engines are not as powerful as hydrogen and oxygen.

It's not so good than the punch.

Methane is simply something that my grandmother doesn't love and my uncle doesn't love.

Yin Chenghai said: "Mr. Su! The methane engine is proven by a global team. It is simply not enough for the fuel of a rocket engine. Whether it's in the first or second level of performance, or in a vacuum, it's not good? The specific impulse is poor, and the dry mass ratio is low. Who the hell did you hear about methane? ”

In Yin Chenghai's opinion, Su Han should not know where to come from, and after hearsay, he actually believed it.

If methane could be used as fuel.

It's better to try the cow dung stuffed by the third brother country!

"The main reason I like methane is because of the high reuse rate of this propellant. We want to build a rocket engine that can be reused many times without carbon deposit. High temperatures and carbon deposits must be addressed. If you want to solve these two problems once and for all, then methane is the only one. ”

Everyone was a little speechless when they heard this.

Just because methane doesn't deposit carbon, so use it?

It's just so funny.

Methane does not deposit carbon, but the problem is that it is not used at all.

The main reason is that the world has not heard of anyone using methane as a fuel for engines.

It seems that Su Han is a little too tendonous.

Thinking about it is a play, and there is no scientific spirit at all.

In the eyes of everyone, although Su Han is a computer genius, he should still be a novice in the field of rockets, and what he thinks is a little too whimsical.

Yin Chenghai was also a little speechless, thought for a while and said, "Mr. Su! Since you want to use a fuel that no one uses. And this engine! Which technology are you going to use? ”

In Yin Chenghai's opinion, no matter what kind of technology he is, he can make the other party speechless.

It is necessary to let this boss know that it is not a whimsical idea to make a rocket engine.

Su Han said: "The engine you studied before is not the engine I want at all. I wanted a disruptive engine. This engine is named by me as a full-flow high-pressure refueling cycle staged combustion engine. ”

Everyone was stunned!

Because they haven't heard of such engines at all?

Yin Chenghai said: "Mr. Su! I don't think I've heard of this engine? ”

Su Han said: "Of course you haven't heard of it. I invented it! ”

Invented by Su Han!

The crowd was dumbfounded when they heard this.

Su Han was able to invent the rocket engine.

How is this possible?

Yin Chenghai was also stunned!

Then I was speechless.

The fact that the other party can invent a rocket engine is simply a joke in the world.

Su Han didn't have any birds at all.

Then he took out a tablet.

This computer is the latest product of the Longhan mobile phone and is not yet on the market.

Su Han uses software to project a computer screen onto a projection.

Then he took out a capacitive pen and sketched on it.

Seeing this, everyone stared at the projection screen.

Soon a sketch of an engine appeared on it.

Everyone knew at a glance that this was a rocket engine design plan.

It's just that what shocked them was that they hadn't seen this Fang Eucalyptus at all.

What is this?

Twin pumps and twin motors.

There are still two pre-combustion chambers.

Fuel-rich gas and oxygen-rich combustion actually go their own way.

Isn't there no exhaust gas at all?

This design idea is too awesome!

Yin Chenghai was also shocked.

How to say that he is also an expert in the field of rocket engines.

Naturally, I know the subtleties of this sketch.

The key is the design of double pumps, double pre-combustion chambers, and dual channels.

I've never heard of it before.

Yin Chenghai saw that Su Han finished painting and hurriedly said, "Mr. Su! Did you design this recipe yourself? ”

Su Han said: "Why have you seen it elsewhere before?" ”

Yin Chenghai was stunned, and suddenly said, "Then according to your design, where do you plan to put the oxidizer pump?" ”

Su Han regenerated a picture and redrew it, and soon an engine jumped on the screen.

"Rebirth: The Great Age of Waves"

Su Han then said, "The oxidizer pump is here!" ”

"What about the fuel pump?"

"Of course it's here!" Su Han drew another fuel pump.

"What are you going to do with the gas-rich pipeline?"

"Isn't it okay to get around here!"

"What about the control valves?"

"Put it in this place."

"Then the oxygen-rich pre-combustion chamber is in the way!"

"How can you get in the way! Wouldn't it be nice to connect a line directly next to the fuel pump control valve? ”

Su Han said as he painted.

Yin Chenghai also kept asking.

The two of them are a question and an answer.

No matter what Yin Chenghai asked, Su Han could answer, and more importantly, the structure of the engine was becoming clearer and clearer.

You must know that Su Han's painting skills are also very good.

His engines can be described as lifelike.

Just like that, a beautifully designed engine gradually took shape between the two of them's questions and answers.

Everyone was dumbfounded.

No way!

An engine that has never been seen before in the world was designed in this way.

That's awesome, isn't it?

Yin Chenghai really couldn't ask anything in the end.

Because this engine is too complex and perfect.

It can be said that there are no flaws.

No wonder it's called a full-flow engine!

A little bit of energy is not wasted!

Can it not be full traffic.

Yin Chenghai suddenly thought of something and said, "Mr. Su! What is the size of the nozzle in this engine you designed? ”

Su Han said: "One meter three!" ”

One meter three!

Everyone was basically stunned when they heard it.

With a nozzle of one meter and three, this rocket engine is incredibly small.
