The gap is too big.

The key problem is that you don’t need a good engine.

Use bad ones.

I really don’t know what Su Han is thinking?

Guan Kai said: "Mr. Su! Why don't you use the Fire Dragon H2 engine? Didn't the Fire Dragon H2 thrust reach 409 tons?"

Su Han said: "The performance of Fire Dragon H2 is not good. Moreover, Fire Dragon H2 is a disposable engine. We need an engine with stronger performance and can be reused multiple times."

Ding Liangyang said: "Why don't you know how many times your Thunder Dragon l1 design has a design life span?"

Su Han said: "More than a thousand times!"

One thousand times!

Everyone was completely stunned when they heard this.

How can there be an engine in the world with a designed lifespan of up to a thousand times?

Is this still a rocket engine?

Not a car engine!

Ding Liangyang said: "Can you talk about the data of Thunder Dragon l1?"

Su Han said: "No problem! Actually, it is not a big secret. The thrust weight ratio is 110 to 1. The chamber pressure is 340 atmospheric pressure. The pulse is 335. The nozzle area is 1.3."

What!

Everyone heard that this was the boss with a chin.

All can stuff a duck egg.

Because the performance of this engine is so awesome!

The comparison reached 335.

The chamber pressure also reached 340 atmospheric pressure.

The nozzle area is only 1.3.

Thrust 22.

Wouldn't that weigh only two tons?

How is this possible?

How could there be such awesome rocket engine in the world?

Guan Kai said: "Mr. Su! You are not kidding us! How could your engine performance be so strong?"

Su Han smiled and said, "Are you strong? It's okay! In fact, we have a better design plan. But we are still in development now."

Everyone can't say anything at all.

Such a strong engine is not the best!

Anything better?

How is this possible?

Ding Liangyang thought of something and said hurriedly: "By the way, Mr. Su! What fuel does your new engine use?"

Su Han said: "Methane liquid oxygen!"

Methane liquid oxygen!

Everyone was even more incredible when they heard this.

Guan Kai hurriedly said: "This is impossible! Methane liquid oxygen cannot have such a large specific impulse and thrust."

Everyone nodded when they heard this.

Now everyone in the world knows that if you want greater thrust, liquid hydrogen and liquid oxygen are the only ones.

Methane liquid oxygen.

It is impossible to generate such a large thrust.

Su Han just smiled and said, "It may not be possible! It's data that is talking. It's not me that I'm talking. If you don't believe it, I can't do it. In fact, everyone here is also experts, and I don't tell lies in front of real people. The kerosene engine is prone to carbon accumulation, and the liquid oxygen engine temperature is too high and it is easy to burn out. If you want to reuse it, it must be a methane engine. As for the methane engine that has less thrust than the thrust, it's just that the design is unreasonable. As long as the design is properly, the methane engine can also have strong thrust. This is why we chose Thunder Dragon l1 instead of Fire Dragon H2."

Everyone couldn't say anything after hearing this.

These people are experts.

Of course, everyone understands what Su Han said.

But this question is the most interesting thing.

Guan Kai said: "Mr. Su! Then how did you solve the exhaust gas problem?"

Su Han said: "Our Thunder Dragon l1 has no exhaust gas. Because our Thunder Dragon l1 uses a new design scheme called full flow high-pressure recombustion cycle graded combustion. It will not waste any fuel. This is why our engines have such strong performance."

An engine without exhaust gas?

True or fake!

This is completely indescribable.

Although they cannot understand how awesome the so-called full-flow engine of Su Han is.

But just a few words of full traffic also prove its powerful performance.

No wonder Su Han has always been so calm about Rockets recycling technology.

It turns out that they are really confident!

Although everyone had previously admitted that Su Han was powerful.

But everyone also thought that his idea of ​​recycling the Rockets was a bit too whimsical.

But now Su Han is not joking.

It can only be said that the super genius' brains are different from those of ordinary people.

...

Finally, it was the final preparation time before launch.

Everyone stopped talking and stared at the big screen.

Everyone wants to see if Su Han can accomplish this miracle this time.

With the end of the countdown.

Three parallel Leilong l1 engines gushed out a boiling heat flow.

The rocket also slowly left the launch pad and flew towards the sky...

Various telemetry data appear from time to time in the hall.

The cameras on the rocket's body and the telescope on the ground convey various messages to the hall at all times.

The rocket is getting faster and faster.

One thousand kilometers per hour...3 thousand...5 thousand...7 thousand kilometers per hour.

The speed of Dragonfly q2 has reached nearly six times the speed of sound.

One hundred and sixty seconds later.

The rocket has entered an area eighty kilometers from the ground.

In fact, at this time, I have already entered the quasi-space realm.

But Suhan's goal is the Carmen Line.

The Rockets continued to accelerate to 9,000 kilometers per hour, and at seven times the speed of sound, they finally entered the Carmen Line.

It's considered entering space.

There was a sudden warm applause in the hall.

Tens of thousands of employees in the workshop lobby are also looking at the big screen.

Seeing the Rockets finally leaped over the Carmen line.

All staff cheered.

After nearly two years of hard research and development and work.

Finally, I saw the rocket he made himself crossing the Carmen line.

That kind of excitement is also unspeakable.

Many people even had tears in their eyes.

In fact, becoming an astronaut was the dream of most people when they were young.

But as we grow older, this dream gradually fades away.

Because the profession of astronauts is too out of reality.
