Hand rubbing nuclear fusion live in the wilderness

Chapter 476 Lagrangian Points

Riding a small electric donkey, walking on the way to the controllable nuclear fusion park, Won calculated the time and found that almost seven months had passed since the first year of the outer space exploration mission.

This involuntarily made him frown, the first year passed faster than he had planned, seven months passed in the blink of an eye, now there are only five months left, and five months , It is not enough for him to build a miniaturized controllable nuclear fusion reactor and a new type of spacecraft.

Fortunately, a small controllable nuclear fusion reactor can be manufactured in about two months if the number of CNC machining equipment and intelligent robots is sufficient.

But the new type of spacecraft caused by the anti-gravity of the application of the primary magnetic field will not work.

This magnetic field anti-gravity spacecraft needs to carry him to the moon, and the quality needs to be fully guaranteed.

In this case, large-scale 3D printing factories are almost useless, and almost most of the parts have to be processed by CNC equipment.

It is a fact that the parts printed by the printing equipment are not as good as the cast parts. Even if there is a "trialuminum titanium holmium-diyttrium-ammonia carboxy complex material" that can increase the physical properties of the alloy material, it is not as good as Pure native cast parts.

Additive manufacturing and subtractive manufacturing are two completely different concepts.

He was able to apply it to the X-1 industrial robot because even if the industrial robot had quality problems, it would at most damage the robot and lose some property.

It has no effect on his own safety.

But the magnetic field anti-gravity spacecraft is different. If there is a problem in space, he may not even have a chance to escape.

Just like a controllable nuclear fusion reactor, it is impossible for him to use 3D printed parts to manufacture such a dangerously designed device.

Won made a simple calculation. Even with a large number of X-1 industrial robots as the labor force, it may take eight or nine months to complete the construction of a spaceship.

After all, it takes a long time for a spacecraft to go from the manufacture of each part to assembly and testing.

This is not something that can be done simply by adding robots.

He realized that he had thought wrong before. He thought about building the magnetic field anti-gravity spacecraft and then sending the infrared space telescope into the sky, but now he realized that there was not enough time.

Shaking his head, Han Yuan recovered from his thoughts.

The lack of time does not affect him too much. Sending the infrared space telescope to the sky does not mean that it must be done through a magnetic field antigravity spacecraft.

Launch vehicles, space shuttles, etc. are fine.

Especially the space shuttle, he had the experience of making the zero space shuttle before, and it would not be difficult to copy another one.

The only thing to consider is range.

The voyage of the zero space shuttle is not very far, and the limit is almost near the low earth orbit of about [-] kilometers.

If it is farther away, the fuel it carries will not be able to fly back.

The launch point of the infrared outer space telescope, which is undergoing final assembly work, is the second node in the Lagrangian point.

This node is more than 150 million kilometers away from the earth's surface, which is nearly four times farther than the 38 kilometers distance between the earth and the moon.

The reason for choosing such a large distance is because of the properties of Lagrangian points.

The Lagrangian point refers to the spatial position where the resultant gravitational force of two large celestial bodies is equal to the centrifugal force felt by a much smaller third celestial body.

As we all know, all objects have gravitational force, and the greater the mass of the object, the stronger the gravitational force.

For example, when the gravitational force between the sun and the earth meets and contacts in space, a balance point will be created due to the interaction of forces.

And if the spacecraft can enter this balance point, it can always "stop" for observation.

There are five "Lagrangian points" between the sun and the earth that have been discovered by humans.

Among them, the Webb telescope stops at the L150 point 2 million kilometers away.

This L2 point is also a target for the won.

Because the point L2 is on the line connecting the sun and the earth, but in the opposite direction to the sun, at this point, the earth, the moon and the sun are all behind it, thus making this position away from the interference of the sun's heat and light.

Avoiding the sun's heat and light interference is crucial for the space telescope, which makes it more sensitive to tiny infrared signals and thus captures infrared light from deeper in the universe.

In addition, it is precisely because of avoiding the interference of solar heat and sunlight, if an object is placed at this point, its temperature will be much lower than other places, which is more conducive to the work of infrared space telescopes.

That's why Won wants to send the infrared space telescope to the L2 Lagrangian point.

It's just that the L2 Lagrangian point is 150 million kilometers away from the earth. If you want to send a large infrared telescope to such a long distance, the zero space shuttle cannot do it.

After thinking about it, South Korea decided to use the space shuttle + launch vehicle to complete this system.

They are used in combination because both have their own pros and cons.

The disadvantage of the space shuttle is that it does not have as much fuel as a large launch vehicle, but it is controllable and flexible, and can achieve various tasks.

The disadvantage of the launch vehicle is that it takes a long time to send the outer space infrared telescope to the Lagrangian point. The advantage is that the take-off tonnage is larger than that of the space shuttle, and it can transport more things.

But because most of the fuel carried by the launch vehicle is used to break through the first cosmic speed, so when it breaks through low-Earth orbit, it will not carry much fuel.

To send the infrared telescope to the unexpected L150 Lagrange point 2 million kilometers away, it needs to rely on a certain amount of inertia to fly, and it will take a long time, about a month or so.

If it is simply a month, it is actually acceptable.

But the Lagrangian point is a point, but it is actually a space. The infrared telescope launched by the launch vehicle needs to orbit for a period of time to ensure its own safety.

This process takes a long time, at least three months.

The space shuttle is different. After the launch fuel is borne by the launch vehicle, the fuel it carries can support it to make certain adjustments, directly omitting this orbital movement and directly entering the Lagrangian point, thus saving a lot of time. .

Therefore, the combination of the two can help him complete this task.

When we came to the controllable nuclear fusion park, X-1 industrial robots were constantly moving the produced controllable nuclear fusion reactor parts along the way.

Now that the construction of the reactor building has been completed, some of the spare industrial robots have gone to build a shipyard for anti-gravity spacecraft in the distance.

Another part of the industrial robot is arranged to assist him in completing the assembly of the controllable nuclear fusion reactor.

Anyway, Won won't let these industrial robots idle. Now that he is in a state of rapid development, how can he let the scarce labor force idle.

As long as the power is sufficient, these industrial robots can work differently 24 hours a day.

Well, no salary yet.

After all, their wages are used to pay electricity bills and maintenance.

Entering the reactor building, the building that has been completely completed reveals its exquisite side.

The walls are painted with white paint that is fire-proof, waterproof, and dust-proof, while the floor is painted with light green non-slip fire-resistant polyester glue. The lights hanging from the ceiling can illuminate corners once, and each room has complete ventilation. , temperature control, fire protection and other systems.

These things are currently controlled by artificial intelligence Xiaoling. On the one hand, it is convenient, and on the other hand, it can accelerate the growth of Xiaoling.

After all, compared with her predecessor, Xiaoqi, she is still too weak now, and more participation in practice will help collect data and improve intelligence.

Going all the way, Han Yuan came to the central area of ​​the reactor building.

The central area covers a rather large area, exceeding [-] square meters, comparable to a football field.

At this moment, various steel brackets have been set up in the central area. The steel used to build these brackets is not small. The smallest one is as thick as his wrist, and the diameter of the steel used in the largest two sets of gantry brackets exceeds 35 centimeters.

The role of these brackets is to assist the assembly of the controllable nuclear fusion reactor, just like the scaffolding used to build high-rise buildings in reality.

It's just that relatively speaking, these brackets have to bear a higher weight.

Not only the various parts of the controllable nuclear fusion reactor need to be hoisted by these brackets, but also the magnetic fluid power generation equipment needs to be hoisted and fixed on the high-level through these brackets.

The weight of these things is not light, the heaviest single part can reach about two tons.

In addition to the brackets, the components of the controllable nuclear fusion reactors that have been produced are also stored in the central area.

It's just that these parts are still stored in a mouthful of boxes and have not been disassembled.

The camera turned around, and the audience in the live broadcast room immediately saw boxes half-stacked against the wall, as densely packed as bricks.

Han Yuan walked over, and the camera showed the box, no matter how big or small, there are block letters like ink pens on the four sides of the box.

And the box in front of me is marked on it:
"Gamma-nickel alloy No. 24-No. 27 base material for armor in the first wall."

Han Yuan said: "As you can see, all the parts that have been produced have been delivered."

"For example, the box with a diameter of more than two meters in front of you is stored in the gamma-nickel alloy on the first wall."

With that said, Han Yuan opened the box in front of him, revealing the parts inside.

What appeared in front of everyone was a huge silver-white metal plate with a mark on it: "Substrate No. 27."

Han Yuan put on his gloves and reached out to take out the metal plate inside.

The thickness of the silver-white metal plate is about one centimeter, and the holes for rivets can be clearly seen at the four corners. The central area is stepped and raised, and the two sides are flat, which looks a bit like the upper part of a "convex" character.

Showing the silver-white gamma-nickel alloy plate in his hand, Han Yuan said, "This is the outermost material of the first wall, the gamma-nickel alloy plate."

"There are 670 or eight pieces of this metal plate, and they will cover the first wall as a whole without leaving any gaps."

"As for the effect, I won't say much, everyone knows."

After showing the nickel alloy plate in his hand, Han Yuan put it back. In this box, there are three more such alloy plates, which are separated from each other by soft polyester foam in order.

Han Yuan has never doubted the performance of the gamma nickel alloy material.

Not only did he conduct experiments himself, but he obtained detailed data. After obtaining the production method of this alloy material, various countries produced this alloy in large quantities, and conducted experiments to replace the original material of the first wall. .

Not to mention other countries, after resetting the first wall based on the performance of gamma-nickel based on the performance of gamma nickel, the controllable nuclear fusion research institute in Huaguo, the running time of the controllable nuclear fusion reactor has exceeded one hour and three ten minutes, and it is still at 10 Under the high temperature of 7000 degrees.

If it weren't for the water-cooled divertor and the field coil of the controllable nuclear fusion reactor used in the experiment, they couldn't bear it, and the running time could be improved a lot.

And when this data first broke out, it almost shocked the whole world.

You must know that just half a year ago, the highest operating time of Huaguo's 7000 million-degree high-temperature stellarator-controlled nuclear fusion reactor experimental reactor was one minute and 47 seconds.

From one minute and 47 seconds to one hour and three 10 minutes, the running time has almost doubled by a hundred times.

It is no exaggeration to say that if this material is developed by Huaguo itself, then on the road of controllable nuclear fusion, Huaguo's progress can directly surpass all countries in the world.

It is not enough to fight even if all countries unite together.

The only pity is that Huaguo is not very good in the control technology of the water-cooled divertor and the field coil, which also caused the follow-up research progress to lag behind a lot. Lost.

Of course, controllable nuclear fusion is not the only problem with the first wall material. In addition, how to dissipate heat, how to use high-temperature plasma to generate electricity, how to carry out tritium self-sustainability, and high-temperature neutron recovery are all problems.

These problems have not been solved, and no matter how long the running time of the experimental reactor is, it will not be practical for commercial use.

After all, experimental reactors and commercial reactors are completely different concepts.

The former only needs to be able to meet the most basic experimental requirements of plasma experiments, that is to say, it does not consider the issue of power generation at all.

The latter requires the fusion reaction to be stable and run for a long time to output energy.

If the complexity of the former is counted as one star, the complexity of the latter will directly pile up to nine stars, which is simply incomparable.

In the face of commercial piles, all the experimental piles in the world may be regarded as toys.

So even if the South Korean won has almost completely demonstrated the controllable nuclear fusion technology, there is still no commercial reactor built in any country.

The fastest to go, should be Huaguo.

Huaguo has now established a controllable nuclear fusion park in Suzhou Province that is exactly the same as South Korean won. Even the lines for outputting electric energy have been laid, and only waiting for the core reactor to complete construction can generate electricity and run.
