Trisolarans: Trisolarans with the hard steel of the earth

"You, you mean the truth..."

Huang Xingguo's face was flushed, his veins were bulging, and he looked a little frightened.

After all, he has been working on rockets for half his life. If the non-propellant engine really appears, what does it mean?

No air pollution?Environmental friendly?

power saving?

No, it is actually a leapfrog development of aerospace technology.

From the end of the Cold War to the present, the development of aerospace science and technology in various countries has almost stagnated, and everyone is living on their laurels.

There are even countries whose aerospace technology has regressed a lot.

Most of the reasons, besides money, are the engine.

Existing chemical engines are stupid.

Can you imagine that a multi-ton off-road vehicle can carry only the weight of a baby.

This is the current dilemma of chemical rockets.

If you want to carry one more ton of scientific research items, you need to add dozens of tons of fuel.And in most cases, it's not just a simple matter of aggravating.

And the invention of the non-working medium engine is bound to definitely lead to the advancement of aviation technology.

How could he not be excited by this! !

Of course, whether all this is true has yet to be proven.

"Is it true, you can see for yourself?"

Huang Xingguo ran faster than a rabbit with his legs, and he had already reached the tarmac before the plane without propellant landed.

He waited until the plane stopped, and immediately ran to the side, touching the blue light outlet at the bottom of the plane with his hand.

No heat!

Even the temperature of the entire aircraft fuselage is freezing cold.

This also means that the energy conversion efficiency of this aircraft has reached an outrageous level.

Energy is not wasted in excess heat radiation.

And he looked up into the cabin, and found that the space inside was much larger than he imagined.

Really no gas tank?

"Is it really useless???"

Huang Xingguo looked crazy, and ran towards Lin Lang under the eyes of the pilot on the plane looking at each other:

"Lin... Dr. Lin!! You, you give the technical drawings of this engine to..."

As he spoke, he blushed himself.

Why?

Just show you the drawings of other people's engines?

What about the empty glove white wolf?

"About the technical details of the propellant-free engine, I have already summarized detailed information."

Lin Lang seemed to have talked about his thoughts a long time ago, and said calmly:

"When these launch missions are completed, Platoon Leader Huang will take a look."

Is it okay to complete the task?

great...

and many more.

"This...batch?" The smile on Huang Xingguo's face froze: "You...how many times are you going to launch?"

"Actually, not many times, probably just..."

Lin Lang estimated: "That's three to five hundred times."

"?"

……

The rumbling noise is a few kilometers away, and it can even make people cover their ears.

The spray of chemical flame blinded the eyes of those watching from a distance.

The first rocket launch brought about ten tons of nanomaterials into space, and under the guidance of the central computer, it stopped on the geosynchronous orbit.

Huang Xingguo, who was watching from the side, asked Lin Lang hesitantly:

"Why not transport it with your non-propellant engine?"

"Chemical-fueled rockets are absolutely impossible to meet your huge needs."

Every time a rocket is launched, the resources consumed are astronomical.

The purpose of Lin Lang is to transport tens of millions of tons of material to the geosynchronous orbit, which is absolutely impossible to accomplish with chemical fuel rockets.

If it is really used, it is similar to burning paper with banknotes to keep warm.

"During the operation of the engine without working medium, a large amount of electromagnetic interference will be generated."

Lin Lang explained: "High-precision instruments will fail under its interference. In that case, I will lose the meaning of sending materials. And the anti-interference insulation layer is too bulky, so it is not suitable for transportation."

"Then what are you going to do? Anyway, it's impossible to make so many rockets."

"It's actually quite simple."

Lin Lang smiled slightly, without explaining.

For the next few days and nights, Lin Lang waited.

What is sent into space by rockets is not just the materials for making elevators.

And billions of nanobots.

……

Above the synchronous orbit [-] kilometers away from the earth.

In the wreckage of a rocket.

Suddenly, a silvery white light flashed.

Flowing robots emerged from the wreckage, breaking it down into nanoscale alloy materials.

At the same time, the nanomaterials carried by the rocket are also flowing in the robot, slowly plasticizing...

Lin Lang never planned to build a space elevator by relying on the speed of a chemical rocket.

The rocket is just an introduction, like the first domino.

Successfully sending the extremely high-precision construction-type nano-worm swarm to the synchronous orbit is considered a success.

Then, there is the stage for the nano-worm swarm...

The swarm will build nanomaterials into a high-strength working platform.

After the working platform is stabilized, the nanoworms will start to link the materials of the space elevator down little by little, like a spring silkworm spinning silk, until it reaches the ground base.

At the same time, the platform will continue to receive nano-materials delivered by the non-propellant engines on the surface (ordinary rockets are used to transport nano-worms, and non-propellant engines can be used to simply transport materials) to supplement consumption.

In this process, the nano-worm swarm injected with intelligent programs will be the most industrious labor, constantly building their own for human beings...

Sky Garden.

The poor people in Jiamo have no time to look up at the starry sky, let alone think that there is a group of inanimate bugs exhausting their energy for their first step into space just above their heads [-] kilometers away. .

Chapter 46 Classification of Civilization

Boom boom boom...

At the rocket launch base.

Every two hours or so, there was a loud roar.

That was the sound of a small rocket without propellant falling to the ground.

Batches of propellant-free rockets rose from the ground and flew into space as if they did not need money.

After the non-propellant rocket sends the nanomaterial to the platform in synchronous orbit, it will return to the surface according to the procedure.

At the same time, the landing location is precisely controlled within one square kilometer.

And soon someone will recover the wreckage of the rocket and continue to send the next one...

This mass launch of rockets does not seem to save much compared to chemical rocket launches, but it is not.

The entire propellant-free rocket is actually very simplified. Except for the necessary engine, energy system, and simple main control system, the rest of the space is used to assemble nanomaterials.

It can be said that everything that can be simplified has been simplified, including housing materials, redundant systems, and so on.

Not to mention that this rocket can also be recycled.

The cost of one launch is even less than one-thousandth of that of ordinary chemical rockets.

Lin Lang, who was already used to the noise when the rocket landed, took a sip of tea to moisten his throat.

He is explaining the basic structure of the non-propellant engine to Huang Xingguo and a group of scientific researchers at the base.

This technology is too advanced, even if it is placed in the universe of the wandering earth, it is the top of the top.

Therefore, to these researchers, they felt that they were not learning new technologies, but listening to Lin Lang's science fiction.

After they learned that the refrigerant-free engine was made by Lin Lang, they were all astonished.

This is simply a great invention across the century, not to mention that Lin Lang is still blind.

"Dr. Lin, tell me, with this engine, can we...build spaceships!?"

asked a younger researcher.

"Don't think of the spaceship too simply." Lin Lang smiled: "In addition to the engine, the materials of the spaceship, the place where the spaceship is built, and the specific structure are all very particular."
