A series of titanium alloy keel launch missions have caused unimaginable psychological blows to the country on the other side of the ocean.

However, the construction task of Xinggang is still being carried out in an orderly manner.

The unmanned engineering ship stretched out its mechanical arm to firmly grasp the titanium-nickel alloy steel column with a thickness of 15 centimeters.

Then a burst of compressed gas is sprayed from the robotic arm, blowing the dust off the surface of the titanium-nickel alloy keel.

Most of these are interstellar dust contaminated in synchronous orbits.

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 primitive accretion disks, while others are derived from comets that travel around the solar system.

They are affected by the Earth's gravity and have never been too far away from the Earth's gravitational field.

At the beginning of the design, this situation was thought of.

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

Blow away the dust of these macromolecules.

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

The two robotic arms easily approached two titanium-nickel alloy keels hundreds of meters long and weighing nearly 100 tons.

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

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

The laser measuring instrument is constantly determining the distance between the two Titanium-nickel keels.

The two keels, which shimmered with silver on the surface, slowly fit together tightly.

When the arm is released, the two keels appear to be welded together.

On the surfaces that are clinging together, not even a single gap can be seen.

It's as if the two are naturally glued together.

"The low vacuum environment of space gives us the prerequisites for the use of vacuum cold welding."

Zhang Xingyang took a sip of coffee that was already a little cold.

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

Vacuum cold welding, a very rare technology.

It takes advantage of the activity of atoms on the surface of the metal.

In daily life, the surface of the metal is not smooth enough, and there are stains and other reasons, and the activity of atoms is rarely seen.

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

In a vacuum, the atoms between two clean metal surfaces will be very active because there is not enough charge balance.

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

Thus tightly combined.

This combination even goes beyond general welding techniques.

However, the conditions under which it occurs are also harsh.

It can only be realized on a large scale in the space environment.

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

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

There will be no defects such as stress, deformation, cracks, etc.

Secondly, it will be very difficult to separate them after the cold weld has occurred.

Because the surface of the metal is the electromagnetic force between the atoms that bind together.

It's almost impossible to separate them.

"The spindle is almost finished."

Geng Bo kept an eye on the progress of the engineering ship and said to Zhang Xingyang.

The main axis of the starport will be thicker than the secondary axis of the umbrella shape.

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

If it's not more powerful, it's easy to have all kinds of problems.

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

A strong interatomic electromagnetic force tightly connects the titanium-nickel alloy keel weighing tens of tons.

"Start spindle keel testing."

Geng Bo gave 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 starport actually revolves around the main axis.

Centrifugal force is used to simulate ground gravity.

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

If the spindle is torn open, it will have extremely horrific consequences.

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

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

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

The unmanned engineering spacecraft stretched out four robotic arms and grabbed both sides of the keel, and then the hydraulic device began to slowly play.

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

And it is also accompanied by the operation of the hydraulics, which keeps getting bigger.

If it's above the ground, you can hear the metal creaking.

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

You can only see the hydraulics inside the robotic arm, slowly pushing forward.

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

The four robotic arms are still clinging to the titanium-nickel keel, and there has not been the slightest wavering.

"The spindle keel test tension has reached the upper limit, and there is no observable deformation."

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

"It looks like the strength of the spindle keel is up to par."

Zhang Xingyang took a sip of coffee that had been completely cold and said.

Judging by the cold coffee, his heart was far from being as calm as it appeared.

Geng Bo also breathed a sigh of relief and slumped in his chair to relax.

In the past few days, everyone has hardly rested.

All kinds of refreshing means are taking turns.

Strong tea and coffee are almost useless at the end of drinking.

"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 say?"

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

Titanium-nickel alloy keel, to be honest, its performance in space was a bit unexpected by Zhang Xingyang.

It's a little better than he thought.

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

"The day before yesterday, Eagle Sauce should have found our titanium-nickel keel."

Geng Bo sat up slightly and said:

"I don't know what they think, they would think that we are making space weapons."

In the end, Geng Bo even had some indignation:

"And it's a God's scepter, how can we look at such a garbage thing!"

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

The Scepter of God, although very sought after by Eagle Sauce.

But after calculations in China, it has been found that its striking effect is really bad enough.

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

And the concept of a global rapid strike is not too attractive for the domestic community.

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

The effect of microwave strikes is better than that of the Staff of God of kinetic weapons.

In particular, long-distance microwave transmission technology has been established in China.

Satellite long-distance transmission technology.

They can be turned into invisible ultra-ranged killers at any time.

Compared with other electromagnetic wave attack methods, microwave can directly act on the molecular level, allowing the molecule to move at high speed from the inside to the outside, thereby heating.

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

And in the human body, 70% is water.

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

Zhang Xingyang said disappreciatively.

Over the years, he has built up enough knowledge about Eagle Sauce.

Don't look at him every time he is poked at the pain point, he will scream wildly.

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

A dog that barks, doesn't bite!

A dog that can't bark will suddenly give you a mouthful.

"When we finish building our Starport blanks, they will understand what we are going to do."

Unmanned spacecraft, as well as a dozen titanium-nickel alloy keels.

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

Prior to this, countries had basically had their own space weapons programs.

These plans are either carried out publicly or privately.

But without exception.

They are as far away from being put into operation as if they were forever fifty years of nuclear fusion technology.

Now, however, there are people who have actually begun to deploy space weapons.

It's hard not to panic them.

In particular, Zhang Xingyang set the deployment position of the starport in geosynchronous orbit.

Here, all conventional, unconventional means of striking on the ground are rendered useless.

Countries have basically been able to watch.

It's like watching a sword of Damocles slowly take shape above your head.

Even many countries have already felt its cold blade.

At any time, you may cut your own neck directly.

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

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

A titanium-nickel alloy long rod with a length of 450 meters and a mass of one hundred tons, fell from geosynchronous orbit.

It can produce a large crater at least 20 meters deep and 110 meters square!

In this pit, which can be called a small lake, almost nothing remains more than 10 centimeters in size.

Not to mention people, even slightly larger animals can't survive.

Probably, only ants can barely dodge such a blow.

As a result, countries became even more panicked about the sword of Damocles hanging over their heads.

Although the site of the construction of the Star Harbor is far away from them.

Because the geosynchronous orbit is almost always located above the equator.

Its exact point is actually over Gabon.

That is, over the future space elevator base.

No matter which developed country it is, there is a long way to go.

As for Gabon and its neighbors, they do not have the strength to think about it.

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

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

In space, it is not the same as the ground or the sea.

You don't even need a day to cover a distance of thousands of kilometers.

It's just hours, even tens of minutes.

It is able to travel thousands of kilometers to the top of their heads.

Then throw down the long titanium pole, which symbolizes destruction.

Like the spears of the Doomsday Knights, inflicting catastrophic destruction on them.

Because of the existence of the Sword of Damocles, although Eagle Chan has the intention to initiate trouble.

However, the usual tough measures have not been used.

Rather, it is very rare to have the ambassador consult first.

"Recently, we have discovered some unusual man-made objects in space."

"Based on satellite observations, they all appear to have been launched by your rockets."

"I don't know what I can tell you?"

Robert Ram on the other side, as the representative of the Grand Commander, smiled softly with a smirk on his face.

In fact, in my heart, I have long scolded the generals in the country.

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

In the end, Robert was asked to come on this trip to the troubled waters.

The old man sitting opposite him said with a formulaic smile on his face:

"This is my country's latest space exploration equipment, and as for the specific detection purpose, it is a secret of my country, so I can't tell you."

Robert scolded the old man inwardly for.

Their intelligence analysis has come to a conclusion.

These are just titanium steel columns, not detectors at all.

Not to mention the detector, it doesn't even have an energy supply.

It's just an iron lump.

"But according to the observation of China's infrared satellites, it seems that no heat source reaction has been found in it."

The smile on Robert's face was even bigger, as if it were a blooming flower.

"The detection equipment you are talking about is just a long titanium alloy column."

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

"Hehe, of course it's not going to be a full space probe."

"These titanium pillars are part of our plan."

Sun Hongtao still had an unfathomable smile on his face.

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

Robert almost couldn't stop scolding.

But at the last moment, I held back.

"IMHO, it's just too big."

"The length alone has reached more than four hundred meters, where in the world can there be such a big detector?!"

Sun Hongtao remained silent: "It may be that your envoy has seen and heard less, and what we are going to build is indeed the latest space probe." ”

In the design of the star harbor, there are indeed high-resolution optical telescopes, solar radiation detectors, dark matter detectors and other scientific experimental devices.

So Sun Hongtao is right, but he didn't say its most important use.

"Are you sure you're not building a space weapon, the Staff of God?"

Robert really couldn't help it, so he had to ask directly.

"Your Excellency, how is it possible for us to deploy military equipment in space?"

"We're not some country that goes to war every year."

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

Although Sun Hongtao did not explicitly refer to it in his words, it was clearly an allusion to certain countries that have been making trouble around the world.

Robert 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 facilities in space!" (End of chapter)
