A big country of aerospace with black technology

"Will the autorotation engine be installed soon?"

Geng Bo looked at Zhang Xingyang and asked while eating fried rice.

Now is the adjustment period for star port construction.

The design team is making final design adjustments based on the data sent back by Xue Feng from space.

"After the rotation begins, our test has just begun."

Zhang Xingyang was eating porridge, and was still looking at yesterday's work minutes on his mobile phone with his other hand.

The drum-type space station simulates gravity through centrifugal force.

Initially, the simulated gravity will be smaller.

Because it is impossible to determine whether the current strength of the space station can withstand the pull caused by high-speed centrifugal force.

It can probably only simulate one-third of the earth's gravity.

But this is much better than a completely gravity-free environment.

"Will the 3D metal powder printer that was just delivered yesterday be useful?"

Geng Bo asked curiously.

In fact, this 3D printer was temporarily added to the launch list.

It has replaced many finished parts that were originally launched directly into space.

"It should be useful. I have seen their performance during trial operation. They can still produce parts that meet the requirements in a vacuum microgravity environment."

Zhang Xingyang thought about the trial operation scene he saw at the Space Technology Research Institute before and said.

3D metal powder printer can print complex enough parts.

Originally, these parts probably required more than a dozen machine tools and machining centers to complete the manufacturing.

But now you only need such a 3D printer to produce it.

Even if it is manufactured, its strength and other properties will be reduced.

But it is completely sufficient to solve urgent needs.

It uses laser cauterization to shape metal powder.

It is one of the most advanced 3D printing equipment in China.

The cost of a single piece of equipment alone is as high as over 30 million.

If launch costs are included, the total cost of use is even more terrifying.

"But this only solves some of the equipment problems we encountered."

Geng Bo still said worriedly:

"We are still in the design stage for the large amount of equipment that will be used in subsequent expansions."

The construction of the star port is an extremely huge plan.

It is expected to take fifteen years to complete.

The final total mass exceeds 100,000 tons.

This is without counting the large number of spaceships it is equipped with.

"Just take it step by step."

Zhang Xingyang is not too worried.

He is very confident in the country's current technological manufacturing capabilities.

Regardless of the influence of other aspects, the country is fully capable of building a star port of its own on its own.

However, now many partners have been added.

Zhang Xingyang was a little worried that these people might cause trouble to him.

After all, many of them have had misdeeds in this regard.

Fortunately, the domestic construction of star ports is a problem.

Have absolute say.

As long as the other party dares to play tricks, they will be eliminated directly without mercy.

This is one of the reasons why the project team has been able to maintain high efficiency so far.

"check it out."

After Geng Bo checked his phone for a while, he saw an interesting message.

So he handed Zhang Xingyang his mobile phone.

it says above.

[Aerospace workers went on strike in Birmingham to protest against inaction during the construction of the star port. 】

The picture below shows several photos of striking workers.

Birmingham is the aerospace industry center of Old John and has many aerospace technology companies.

But before that, Old John intended to join forces with Eagle Sauce to suppress the star port construction plan.

It's a pity that it failed.

The construction plan of the star port is still proceeding at a high speed.

In this process, the aerospace industry of many countries got a share of the pie.

For example, Gaul has a better relationship with the domestic aerospace industry.

They were assigned a lot of related orders.

The construction of the star port requires a large amount of high-precision equipment.

It is basically difficult to satisfy domestic production capacity alone.

Therefore, there are many divisions.

Toulouse was overwhelmed by a massive equipment order overnight.

Although before this, the cooperation between the two parties on the Mars exploration plan was not very pleasant.

But in the face of interests, the Gallic Roosters still put down their reserve.

A package of aerospace cooperation plans was quickly signed to fully support Longguo's star port construction plan.

As a veteran aerospace industry city, Birmingham has seen its peers make a lot of money.

Naturally, he was extremely jealous.

But just when they wanted to join the star port construction plan.

was blocked by an extremely powerful force.

So they were forced to give up.

The result is a decline in Birmingham's overall revenue.

The city has even reached the brink of bankruptcy.

There are even problems with the payment of wages in public industries.

This aroused workers' emotions and led to large-scale strikes and demonstrations.

This is what Zhang Xingyang saw.

"This is bound to happen, just because we are ahead of schedule."

Zhang Xingyang said after taking a sip of porridge.

Birmingham would be bankrupt if not today.

According to my own memory, it will still go bankrupt due to financial problems more than ten years later.

But now it is experiencing tax revenue shrinkage and bankruptcy because its pillar industries are squeezed by the Dragon Kingdom.

Then it went bankrupt due to other problems.

"It's really incredible. Birmingham is also John's second largest industrial city, but the industry has shrunk to this extent?"

Geng Bo took back his mobile phone and looked at the news reports.

"Instead of worrying about Birmingham, it's better to think about whether Xue Feng and the others can complete the installation of the autorotation engine today."

Zhang Xingyang finished his breakfast and said before leaving.

The installation of the autorotating engine is actually similar to the installation of the Hall thruster.

It’s just that the autorotating engine needs to be installed on the opening of the aluminum alloy plate.

Return to Starport for the second time.

Xue Feng will still be shocked by the giant star port.

A very large wheel with a diameter of 900 meters lies quietly in space.

The background is an endless sea of ​​stars.

The light of the stars is blocked by the huge wheels.

And such a huge space giant will usher in further growth in their hands!

"The No. 1 autorotation engine is about to be installed."

After Xue Feng made a report, he was ready to start working.

The No. 1 autorotation engine and the No. 2 autorotation engine must be installed on the main shaft.

Used to maintain spindle stability.

When the autorotation engine on the cabin section is started, the main shaft autorotation engine will be started.

Otherwise, the spindle will start to rotate slowly due to force transmission.

The outer layer of the spindle has been covered with a layer of super fluid.

Xuefeng piloted the Tiangong Engineering spacecraft and first flew to the top of the main axis.

Prepare to operate the robotic arm and remove the temporary propulsion system-Hall thruster originally installed here.

"Liu Sheng, prepare to turn off the power of Hall Thruster No. 1."

Xue Feng said within the communication system.

Liu Sheng, who had already entered the Tiangong-1 unmanned spacecraft, turned off the power supply switch of the No. 1 Hall thruster on the control host.

"The power supply to the No. 1 Hall thruster has been turned off."

After confirming that the power of the Hall thruster is turned off.

Xue Feng carefully removed the power cord and air supply pipe from the double-ring Hall thruster.

The rotational balance engine has a thrust far greater than the previous Hall thruster.

The power of the Hall thruster is too small.

It is difficult to maintain the balance of the central spindle when the giant wheel is turning.

The autorotating engine uses liquid oxygen and liquid hydrogen fuel to drive the spindle to maintain stability.

"The installation of the No. 1 autorotation engine has been completed."

A bicycle-sized autorotating engine is mounted on one side of the main shaft.

Xue Feng quickly started installing the No. 2 rotational engine.

It’s still the same installation process as before.

However, based on the first experience, the second installation took a shorter time.

The installation of the No. 2 autorotating engine was quickly completed.

"Get ready to start the spindle rotation test."

Xue Feng said after reporting to the ground command center.

As the hydrogen-oxygen engine started, bursts of blue flames shot out from the tail nozzle.

The main shaft wrapped in the superfluid began to rotate at a low speed.

Then slowly speeding up, the light blue flames drew a bright blue ring in the dark space.

"This scene is so beautiful, like two blue stars very close to me."

Xue Feng wrote in his diary quite literaryly.

The construction of the star port also abides by many rules for ground construction.

One of the tasks that must be done every day is to write a work diary.

"The spindle deviation is two ten thousandths, which is still within the acceptable range."

After the autorotating engine stops accelerating.

Because of the superfluid, the spindle did not stop rotating.

Instead, it still keeps rotating at a constant speed.

You can even keep this speed going for a long time.

It's just that during the rotation process, it will slowly reduce its speed.

Because the main axis is wrapped in a large amount of superfluid, eccentricity problems will also occur.

But according to the test, the eccentricity is very small.

There will be almost no impact on the spindle.

"Preparing for installation of bulkhead autorotation engines."

The installation of bulkhead autorotating engines is more difficult than that of main shaft autorotating engines.

Because the bulkhead is an arc-shaped aluminum alloy plate, the Tiangong Engineering spacecraft cannot be directly attached to it for installation.

When installing the main shaft, the mechanical arm can be used to firmly grasp the main shaft to fix the spacecraft.

After a busy day, Xue Feng has not yet completed the installation of a bulkhead rotation engine.

Just testing the relative speed of the star port and the spacecraft took a lot of time.

"According to the current progress, will our supplies this time be enough to complete the installation of all bulkhead rotation engine ideas?"

Liu Sheng asked during dinner and rest in the evening.

Their supplies are limited, and the time they can live in the star port is not too long at a time.

If the ground does not launch living materials into synchronous orbit.

Then they must return to Tiangong Space Station for supplies.

Xue Feng took a bite of the steamed bun and drank a sip of the brewed juice.

"If nothing unexpected happens, our current supplies are completely sufficient."

But in the universe, any unexpected arrival is very sudden.

It’s also difficult to predict.
