A big country of aerospace with black technology

A series of titanium alloy keel launch missions have caused unimaginable psychological impact on the countries on the other side of the ocean.

However, the construction task of the star port is still proceeding in an orderly manner.

The unmanned engineering ship stretched out its mechanical arm to firmly grasp the fifteen centimeter-thick titanium-nickel alloy steel column.

Then a blast of compressed gas was ejected from the robotic arm, blowing away the dust on the surface of the titanium-nickel alloy keel.

Most of this is interstellar dust contaminated in synchronous orbit.

Although the density of matter in space is very low, there is still a large amount of interstellar dust in the solar system.

Some of them are remnants of the original accretion disk, and some are derived from comets that constantly shuttle through the solar system.

They are affected by the earth's gravity and never leave the earth's gravitational field too far.

This situation was considered at the beginning of the design.

Therefore, the engineering ship will spray a layer of compressed hydrogen on the keel surface.

Blow away the dust from these large molecular clusters.

After completing the cleaning of the titanium-nickel alloy keel surface.

Two robotic arms easily moved two titanium-nickel alloy keels that were hundreds of meters long and weighed nearly one hundred tons, slowly approaching.

The keel is above the ground and has been surface treated.

The surface roughness is less than 0.05 and has undergone a series of super-fine grinding and polishing treatments.

The laser measuring instrument continuously determines the distance between the two titanium-nickel alloy keels.

The two keels, whose surfaces shone with silver light, slowly and tightly stuck together.

After the robotic arm is released, the two keels seem to be welded together.

There is not even a slight gap visible on the surfaces that are so close together.

It's like the two were born to stick together.

"The low vacuum environment in space gives us the prerequisites for using vacuum cold welding."

Zhang Xingyang took a sip of the already cold coffee.

"In this way, we can complete the connection of structural parts in space without using automatic welding robots."

Vacuum cold welding is a very rare technology.

It exploits the activity of atoms on the metal surface.

In daily life, the activity of atoms is rarely seen on metal surfaces due to insufficient smoothness and stains.

This performance can almost only be seen on highly smooth metal surfaces in a vacuum environment.

In a vacuum, the atoms between two clean metal surfaces will show strong activity because there is insufficient charge balance.

Therefore, when two surfaces come into contact, the metal surfaces will spontaneously attract each other due to their positive and negative charges.

thus being closely integrated together.

This combination even goes beyond ordinary welding techniques.

But the conditions for its occurrence are also more stringent.

Only in the space environment can it be realized on a large scale.

And compared with traditional heating or melting of materials to achieve welding, vacuum cold welding has many advantages.

First of all, because the material is not heated, the metallographic phase of the material will not be changed.

It will not cause stress, deformation, cracks and other defects.

Secondly, it will be very difficult to separate them after cold welding occurs.

Because the metal surface is held together by electromagnetic forces between atoms.

It is almost impossible to separate them.

"The spindle is about to finish welding."

Geng Bo said to Zhang Xingyang while closely watching the work progress of the engineering ship.

The main axis of the star port will be thicker than the umbrella-shaped secondary axis.

After all, all the facilities are actually hung on it.

If it is not more powerful, various problems will easily occur.

Four titanium-nickel alloy keels of the same size are connected together by vacuum cold welding.

The powerful electromagnetic force between atoms tightly connects the titanium-nickel alloy keels weighing tens of tons.

"Start spindle keel test."

Geng Bo issued the spindle test order.

One of the most important indicators of the spindle is the degree of connection between the various keels.

Because the entire star port actually rotates around the main axis.

Simulate ground gravity through centrifugal force.

Once the centrifugal force is out of balance, the spindle keel will face extremely powerful tearing force.

If the main shaft is torn apart, extremely horrific consequences will occur.

The entire wheel-shaped star port will be torn into several pieces of different sizes.

Therefore, the main shaft keel must be able to withstand such a powerful tearing force.

As for the testing method, it is also very simple.

The unmanned engineering spacecraft stretched out four mechanical arms and grasped both sides of the keel, and then the hydraulic device began to work slowly.

The pulling force between the four mechanical arms reached tens of tons in an instant!

And it keeps getting bigger with the operation of the hydraulic device.

If it is above the ground, you can also hear the sound of metal creaking.

But in the vacuum environment of space, sound is lost as a sound transmission medium.

Only the hydraulic device inside the robotic arm can be seen, slowly pushing forward.

If you just look at the external camera picture, you will even feel like you are looking at a still picture.

The four robotic arms are still tightly attached to the titanium-nickel alloy keel without any wavering.

"The test tension of the spindle keel has reached the upper limit and no observable deformation has occurred."

After the laser measuring instrument measures, it is still the same number as before.

"It seems that the strength of the main shaft keel is up to standard."

Zhang Xingyang took a sip of the completely cold coffee and said.

Judging from the cooling coffee, he was far from as calm as he showed.

Geng Bo also breathed a sigh of relief and sat down on the chair to relax.

In the past few days, no one had much rest.

All kinds of refreshing methods are taking turns.

Strong tea and coffee almost lose their effect until the end.

"Brother Xingyang, have you heard?"

After resting for a few minutes, Geng Bo looked at Zhang Xingyang beside him and said.

"I've heard a lot of things, which one do you want to talk about?"

After drinking the cold coffee in one gulp, Zhang Xingyang looked at the data in front of him and said.

To be honest, the performance of the titanium-nickel alloy keel in space was beyond Zhang Xingyang's expectations.

Even better than he thought.

Especially in various strength tests, the performance is much better than the tests on the ground.

"Ying Jiang probably discovered our titanium-nickel alloy keel the day before yesterday."

Geng Bo sat up slightly and said:

"I don't know what they think. They think we are making space weapons."

At the end, Geng Bo even felt a little aggrieved:

"And it's also something like the Staff of God. How can we like such a rubbish thing?"

"We published an article long ago denying this weapon setting!"

The Stick of God, although it is very popular among Eagle Sauce.

However, after calculations in China, it has been found that its impact is really bad.

Both the strike range and penetration depth are far inferior to conventional weapons.

The concept of global rapid strike is not very attractive to the country.

"If we really want to build space weapons, we must also use microwave weapons directly!"

The strike effect of microwaves is better than the Rod of God, which is a kinetic energy weapon.

In particular, China already has long-distance microwave transmission technology.

Satellite remote power transmission technology.

They can turn into super long-range killers that can kill people invisibly at any time.

Compared with other electromagnetic wave attack methods, microwaves can directly act on the molecular level, causing molecules to move at high speed from the inside out, thereby heating.

Especially for objects with large water content, it has good heating performance.

The human body is seventy percent water.

"Don't pay too much attention to these, just do our own thing."

Zhang Xingyang said nonchalantly.

Over the years, he has built up enough knowledge about eagle sauce.

Don't look at him screaming crazily every time he is poked at a painful point.

But actually, it’s like what people often say.

A dog that barks but doesn't bite!

Only a dog that doesn't bark will suddenly give you a bite.

"When the rough construction of our star port is completed, they will understand what we are going to do."

There are unmanned spacecrafts in space and more than a dozen titanium-nickel alloy keels.

It has indeed brought unimaginable pressure to many major countries in the world.

Before this, although countries basically had their own space weapons programs.

These plans are carried out either publicly or privately.

But there are no exceptions.

They are as far away from being put into use as nuclear fusion technology is forever fifty years away.

However, now someone has actually begun the deployment of space weapons.

It's hard not to make them feel very panicked.

In particular, Zhang Xingyang set the deployment location of the star port in geosynchronous orbit.

Here, all conventional and unconventional strike methods on the ground lose their effect.

Basically, all countries can only watch.

It was like watching a Sword of Damocles slowly take shape above his head.

Many countries have even felt its cold edge.

He may cut his own neck directly at any time.

Especially after the scientific departments of various countries have estimated the quality and impact effect of titanium-nickel alloy keels.

Even if it is calculated according to the strike model given by Zhang Xingyang before.

A 450-meter-long titanium-nickel alloy pole with a mass of one hundred tons fell from geosynchronous orbit.

It can create a large pit that is at least 20 meters deep and 110 meters in diameter!

In this pit, which can be called a small lake, there is almost no material that remains more than 10 centimeters in size.

Not to mention humans, even slightly larger animals would not be able to survive.

Perhaps only ants can barely escape such a blow.

As a result, all countries became even more frightened by the Sword of Damocles hanging above their heads.

Although the construction site of the star port is far away from them.

Because geosynchronous orbits are almost always located above the equator.

Its exact location is actually over Gabon.

That is, over the future space elevator base.

No matter which developed country it is, it is still far away.

As for Gabon and its surrounding countries, they do not have the energy to consider this issue.

They have a hard time solving problems on the ground, let alone problems in space.

But in the eyes of the country represented by Yingjiang, this is a very small distance.

In space, it is different from the ground or the sea.

It doesn't even take a day to cross a distance of thousands of kilometers.

Just a few hours, or even dozens of minutes.

It can travel thousands of kilometers to reach their heads.

Then he threw down a long titanium alloy pole that symbolized destruction.

Just like the spear of the Doomsday Knight, causing catastrophic destruction to them.

Because of the existence of the Sword of Damocles, even though Ying Jiang deliberately wanted to cause trouble.

However, consistent tough measures were not adopted.

Rather, it is very rare for the ambassador to conduct consultations first.

"Recently, we have discovered some unusual artifacts in space."

"Based on satellite observations, they seem to be launched by your rockets."

"I don't know if I can tell you what these are?"

Opposite Robert Ram, as the representative of the commander, smiled softly with a fake smile on his face.

In fact, in his heart, he had already scolded the generals in the country.

They are incompetent and unable to find out what these are.

In the end, Robert was asked to take a trip through this muddy water.

The old man sitting opposite said with a formulaic smile:

"This is our country's latest space exploration equipment. As for the specific detection purpose, it is our country's secret. I'm sorry I can't tell you."

Robert mentally scolded the old man for talking nonsense.

Their intelligence analysis has reached its conclusion.

These are just titanium alloy steel pillars, not detectors at all.

Let alone a detector, it doesn't even have an energy supply.

It's just a piece of iron.

"But according to our country's infrared satellite observations, it seems that no heat source reaction has been found in it."

The smile on Robert's face broadened, like a blooming flower.

"The detection equipment you mentioned is just a long titanium alloy pillar."

Robert's inadvertent words proved that they already knew the material of these pillars in space.

"Haha, of course it won't be a complete space probe."

"These titanium alloy pillars are part of our plan."

Sun Hongtao still had an enigmatic smile on his face.

"It's just a structural part of our new space exploration equipment."

Robert almost couldn't hold back his curse.

But at the last minute, I still held back.

"With all due respect, it's just too big for its size."

"The length alone reaches more than 400 meters. Where in the world can there be such a large detector?!"

Sun Hongtao said calmly: "That may be because your envoy has less knowledge. What we are going to build is indeed the latest space probe."

Among the design plans of the star port, there are indeed scientific experimental devices such as high-resolution optical telescopes, solar radiation detectors, dark matter detectors, etc.

So what Sun Hongtao said is correct, but he didn't mention its most important use.

"Are you sure you're not building a space weapon - the Rod of God?"

Robert really had no choice, so he had to ask directly.

"Your Majesty, how can we deploy military equipment in space?"

"We are not some country that starts a war every year."

"Our attitude towards space has always been peaceful use and joint development."

Although Sun Hongtao did not explicitly refer to his words, he was obviously alluding to certain countries that have been causing trouble around the world.

Robert instead breathed a sigh of relief.

In this way, country C really has no idea of ​​building the Rod of God.

At the end of the meeting, Sun Hongtao said loudly:

"These are just our civilian space facilities!" (End of Chapter)
