A big country of aerospace with black technology

"Do we really have this weapons research plan?"

Sun Hongtao asked Zhang Xingyang curiously.

"Mr. Sun, this is really not a weapon."

"It's just an electromagnetic accelerator!"

Zhang Xingyang took the trouble to explain to Mr. Sun the situation of the accelerated orbit.

"But it can be turned into a weapon, can't it?"

Mr. Sun asked rhetorically.

"It's like synthetic ammonia, it can be a fertilizer for agriculture, or it can be an explosive that brings death."

Zhang Xingyang was speechless.

Because Mr. Sun was right.

Even if he doesn't want to turn electromagnetic rails into weapons.

Nor could he prevent others from using electromagnetic acceleration orbits for space weapons.

Even out of consideration of being one step ahead of the enemy.

The latest application of electromagnetic railguns is the star port.

Because both in terms of technical reserves and actual construction capabilities.

Dragon Kingdom has such strength.

"This is our design drawing."

Zhang Xingyang didn't pay much attention to the weaponization of electromagnetic acceleration orbits.

In the future, electromagnetic kinetic energy weapons will be standard equipment in space battles.

I just accelerated this historical process by a long way.

"The width of the electromagnetic accelerator tube is 20 meters, and the design specifications can accelerate the spacecraft to more than 10,000 kilometers per second."

"Mr. Sun, do you know what the consequences of such a blow will be?"

Since everyone has the idea of ​​weaponization.

Zhang Xingyang believed that he had an obligation to remind everyone of the horror of such a blow.

"It's not very clear. Please tell me."

Sun Hongtao shook his head.

"An asteroid with a length, width and height of five meters has a mass of about 425 tons."

"When it is accelerated to 10,000 kilometers per second, the kinetic energy will reach 2.15*10^19 Joules."

Zhang Xingyang casually listed a series of numbers.

I know that Sun Hongtao doesn't have much concept of energy.

Zhang Xingyang continued: "The explosive energy of a meal of TNT is approximately 4.182*10^12 joules."

Sun Hongtao finally had a little idea.

"The kinetic energy of such a very small meteorite in space can reach the equivalent level of 10 million tons of TNT."

Zhang Xingyang said with a serious face:

"And this falls within the category of conventional strikes, which will not produce any nuclear contamination and can be launched without restraint."

A meteorite that may only be considered a big rock on Earth.

Being electromagnetically accelerated into an orbit and accelerated to 10,000 kilometers per second, it can produce an effect comparable to that of a super nuclear bomb.

One blow could completely wipe a city with a radius of dozens of kilometers off the map.

It originally looked like a solid reinforced concrete fortress.

Under such a kinetic energy blow.

It's like tofu encountering a hot knife.

It can be destroyed directly without any effort at all.

The upper limit for kinetic weapons is actually very high.

Because it uses a very simple principle, that is, the kinetic energy formula.

Human beings have been using this principle since ancient times.

Sling, a spinning stone thrown.

And meteorites blasted out after electromagnetic acceleration in space orbit.

In essence, there is no difference.

Their power is just a manifestation of the kinetic energy formula.

"But I remember, didn't your previous paper indicate that space kinetic energy strikes would not have such a strong effect?"

Sun Hongtao asked, remembering an important article published by Zhang Xingyang.

This article originally didn’t receive much attention.

But when Yingjiang shouted that Longguo was constructing the Stick of God.

This article attracted the attention of many people.

The number of downloads soared from hundreds to hundreds of thousands overnight.

"Mr. Sun, you also know the two conditions for kinetic energy."

Zhang Xingyang explained:

"The first thing is quality."

"The titanium-tungsten alloy rod in that article only weighs 140 kilograms."

"But a meteorite that is five meters long, wide and high has a mass three thousand times that."

"In fact, if we use a meteorite that is ten meters long, wide and high, the mass will continue to soar to 24,000 times that of the titanium-tungsten alloy rod."

"The impact of quality is actually smaller, and the impact of speed is exponential."

"At that time, we only accelerated the titanium-tungsten alloy rod to 14 times the speed of sound, which is 4.76 kilometers per second."

"It is more than two thousand times different from the speed of electromagnetic acceleration."

"After many times of superposition, their energy levels differ by 12 billion times!"

The kinetic energy of a titanium-tungsten alloy rod with an original mass of 140 kilograms and a speed of 14 times the speed of sound may only be equivalent to a high-explosive bomb.

But the power of this high-explosive bomb is amplified 12 billion times.

Its power will also far exceed that of a large 5-megaton nuclear bomb.

In fact, most of the world's nuclear-weapon countries are equipped with small nuclear bombs of less than 500,000 tons.

For the first time, Sun Hongtao intuitively felt the horror of multiple superpositions of kinetic energy formulas.

"That's just accelerating the meteorite to three percent the speed of light."

“According to our plan, we will eventually build an electromagnetic orbital accelerator that can accelerate a spacecraft to ten percent of the speed of light.”

"At that time, the strike power you see will continue to increase by an order of magnitude."

Zhang Xingyang said seriously.

There is actually only one index for evaluating the impact of weapons since ancient times.

That's the level of energy utilization.

In the cold weapon age, the main source of energy utilization was humans.

The arm uses the body's chemical energy to convert into kinetic energy.

The efficiency is relatively low.

Of course, there are also winch trebuchets, bed crossbows, etc. that make simple use of mechanical energy.

But their energy level may not even be 10,000 joules.

In the industrial era, the sources of energy utilization became coal, oil, and gunpowder.

After the hammer activates the bullet primer, the flame explodes instantly, converting chemical energy into kinetic energy.

The power of weapons is greatly increased!

All carbon-based life forms on the earth are unable to defend against such a kinetic attack.

The energy level rises to the 10^10 Joule level.

In the nuclear energy era, the energy utilization level has been pushed up by several orders of magnitude.

The most powerful Tsar Bomb in history, the energy level was increased to 10^19 Joules.

This is also the highest energy level created by humans so far.

And once the construction of the electromagnetic acceleration track is completed.

Then this number will continue to rise.

The kinetic energy of a 10-meter meteorite can reach 1.6*10^20 joules.

If the meteorite speed continues to be increased, the energy level can even be pushed to the 10^21 Joule level.

The energy continues to climb another level.

They all mean a great progress in human civilization and technology.

"We need to continue to have a good discussion about this."

After thinking for a few minutes, Sun Hongtao still couldn't think of an effective way to combat this attack.

The attack trajectory of a meteorite is very easy to spot.

After all, it has not reached the speed of light and cannot avoid radar waves traveling at the speed of light.

But being able to discover it doesn't mean it can be blocked.

It is assumed that the electromagnetic accelerator tube is built in a geosynchronous orbit of 36,000 kilometers.

Then after completing the acceleration, the time it takes for the meteorite strike to reach the designated position.

Only 3.6 seconds!

At this time, let alone human-controlled air defense equipment.

Even computer-controlled anti-aircraft weapons may not be able to complete the startup work.

It's so fast!

All current anti-aircraft weapons are as fragile as a piece of paper when faced with a speed of 3% of the speed of light.

It will break with one poke!

"But when it comes to the design and manufacture of electromagnetic acceleration orbits, you should follow your own plans."

Sun Hongtao sighed and said:

"Actually, I really want to see what such a powerful weapon would look like!"

At the same time, Sun Hongtao also realized that space is increasingly becoming an important part of war.

In the past, only satellites could exist in space.

Countries only use it as reconnaissance equipment.

It's like the aircraft that have just been put into use are basically reconnaissance aircraft.

But as technology advances, space will inevitably become another battlefield.

In past wars, air superiority was regarded by major powers as a power that must be seized at the beginning of the war.

Sun Hongtao can think of the future war.

Whoever can truly dominate space can truly own everything.

In the past, after occupying the sky, it was necessary to use expensive precision-guided munitions to destroy important enemy targets.

But after occupying space dominance.

Just an electromagnetic accelerator can completely block all enemy ground activities.

In space, there are many meteorites with a diameter of one kilometer.

Meterite slugs several meters in size are cut from them.

Able to produce thousands.

All this can be done with the help of high-energy lasers.

Then the electromagnetic acceleration orbit can accelerate these meteorite warheads to speeds of tens of thousands of kilometers per second.

Then scatter them toward the ground.

A blow like a violent storm!

It can cause devastating blows to areas thousands of kilometers long and wide.

The originally flat ground will be smashed by violent meteorite warheads, creating dense craters like those on the moon's surface.

The strong air wave formed by the explosion can even tear apart even small mountain peaks.

Volcanoes that were briefly dormant will become active again, spewing plumes of smoke thousands of meters high.

On the earth, it is almost a doomsday scene.

Even if there are humans who survive, the land where he is.

Basically also declared dead.

And for all these blows, the attacker only paid for a common asteroid in space and a part of its energy.

Unlocked molten salt reactor and microwave wireless power transmission technology.

The use of energy in space has long been no longer a problem.

So for the attacking side.

The cost of strike is even much cheaper than fighting a war on the ground.

Whether it is the ability to use electromagnetic acceleration or the cost of warhead processing.

All added together, it will not exceed 10 billion.

But a war will burn tens of billions a day.

"I think if such a weapon is really built."

Zhang Xingyang has different ideas from Sun Hongtao.

"Then no one would want to do this to themselves."

"Its biggest effect is actually deterrence."

"Of course, launching a spacecraft to the moon is also very useful."

The greatest role of electromagnetic acceleration orbits is in future interstellar colonization activities.

Although its speed is too high to launch a spacecraft carrying humans.

But there is still no problem in launching some cargo spacecraft.

——

"Report to the ground command center that the installation of 18 Hall thrusters has been completed and pipeline installation is in progress. Please give instructions."

Xu Ying worked continuously for eleven hours and finally installed all the Hall thrusters in place.

However this is only the first step.

Subsequent pipeline installation is even more troublesome.

For the Hall thruster, there are two cables that need to be installed.

They are the radon gas delivery pipe as propellant, and the cable connecting the ionization device.

Pipelines cannot directly allow them to dangle in space.

Cables that are not fixed can easily shift and become tangled.

Therefore, Xu Ying needs to gather these pipelines along the keel and fix them together.

Then connect it to the controller inside the Tiangong-1 unmanned spacecraft.

The fixing method is also very simple and unpretentious.

Just use cable ties to tie the cables directly to the keel.

Anyway, these are only for temporary use, and there is no need to consider subsequent use.

When construction begins, these Hall thrusters will be dismantled.

Of course, they will not be scrapped directly.

If it is in good condition and can be used twice, it will become part of the starport's attitude adjustment engine system.

Xu Ying operated two robotic arms. One robotic arm held the cables, and the other robotic arm used fixed cable ties to fix them.

The fixation of cables is not as strict as the installation of Hall thrusters.

As long as you can secure the cable, you're done.

Therefore, Xu Ying's work speed has become much faster.

Eighteen Hall thrusters took more than twenty hours of work.

But it took less than three hours to completely secure their cables.

Xu Ying had been working for nearly thirteen hours that day to complete the fixing of the cables.

Both physical strength and energy have reached their limits.

"Report to command center."

"Eighteen strands of cables have been fixed and the final connection work is expected to begin tomorrow."

Xu Ying reported tiredly to the ground command center.

This time, Xu Ying did not recombine the Tiangong-2 spacecraft with the Tiangong-1 spacecraft.

Instead, let the robotic arm grab the keel of the star port and end today's work.

After washing up, Xu Ying opened her notebook.

Start journaling.

[July 13, 2007, the weather was cloudy]

[Today is the fourth day in space, and more than half of my work has been completed. 】

[Hopefully I can finish all the work tomorrow so that I can have a few days to rest. 】

I briefly recorded today’s work content.

Xu Ying turned off her tablet and looked up out of the window.

Whenever she looks at the earth from space, Xu Ying's heart will be aroused.

"After tomorrow, you can see this kind of scenery every day."

With this thought, Xu Ying fell into sleep.

The completion of the installation of the Hall thruster does not mean the end of Xu Ying's work.

He needs to wait for the Hall thrusters and all debugging to be completed before he can count all the work this time as completed.

After all, the star port is too far from the ground and it is too difficult to visit once.

All work must be completed at once.
