Chapter 340: Construction Seminar!
The titanium-nickel alloy keel, under the action of vacuum cold welding, was quickly built.
Even because of the weightless environment, the construction speed is much faster than the construction speed on the ground.
The central spindle and the secondary spindle attached to both ends have been assembled.
From the outside, it looks like two umbrella handles joined together, and then the umbrella surface is removed.
The surface of the alloy that has undergone super-fine grinding and polishing treatment reflects the brilliance of stars hundreds of millions of kilometers away.
It emits a silvery-white glitter.
"There have been a lot of reports of meteor sightings lately."
Geng Bo said while playing with his phone.
"There are a lot of reflections on our starport at a glance."
Titanium-nickel alloys are very strongly reflective because the silvery-white refractive index is very high.
When the reflection crosses the ground, the brightness can even reach -1.6 degrees.
More than most of the stars in the night sky.
Only a few planets in the inner solar system are able to shine beyond it.
For example, Venus.
"Stop scrolling Weibo, it's going to be a meeting soon."
Zhang Xingyang glanced at him and said.
The development rate of the electronic technology tree in this world is much faster than in previous lives.
The development speed of smartphones is already equivalent to the level of 2010-2012 in the previous life.
A variety of new social platforms have also entered everyone's field of vision.
Among them, the Weibo platform attracts the most users.
Geng Bo is also one of them.
Even because I am too busy at work and in an area without a network.
Geng Bo played Weibo, and he was even more addicted than ordinary people.
And the sighting report he just talked about is a variety of photos and texts posted by everyone on Weibo on the topic of meteors.
"Yes, yes."
Geng Boyi reluctantly put down his phone, and then complained to Zhang Xingyang.
"Everyone hasn't arrived yet, so it's probably quite early to start."
This meeting will discuss the next construction plans of Starport.
The main framework of the starport has been completed.
But it's also the easiest step.
Subsequent large-scale arc chambers, or various moving components.
The installation difficulty is far greater than that of the spindle assembly that has been the phenomenon of vacuum cold welding.
After waiting for a few more minutes, the last person in charge of the relevant unit came to the scene.
It is the world's largest space project.
The Star Port Project involves more than 30,000 different design, production and manufacturing units in China.
There are more than 1,000 units directly related to the aerospace field.
Responsible for providing all kinds of equipment and services required by Starport.
Today's participants are more than 100 units that are the most important and the most core.
"Now that we're all here, let's get straight to today's topic."
After Zhang Xingyang saw the guards close the door of the auditorium, he didn't give everyone present time to react.
Straight to the point.
"According to the original plan, the Institute of Space Technology was responsible for the development of the cabin."
Zhang Xingyang looked at the crowd sitting on the left side of the first row.
They are responsible for the development of the arc chamber.
"Tell me about your current work."
After Zhang Xingyang finished speaking, a staff member in the audience immediately handed them the microphone.
An old gentleman with gray hair stood up and said:
"We have just completed the processing problem of large-size arc-shaped aerospace aluminum, and we are further improving the relevant manufacturing technology."
The radius of the starport, which was initially 450 meters, will eventually increase to 10 kilometers.
Such a huge size brings unimaginable difficulties to production and processing.
In particular, aerospace aluminum is processed as the outer wall of the cabin.
"We are still developing processing technology for the space environment."
The old gentleman spoke of the many difficulties he was encountering.
"We lack a vacuum loss-in-weight laboratory on a large spatial scale, and progress in this area is slow."
Most of the processing processes in Starport are carried out in space.
Because the oversized finished module cannot be launched directly from the ground.
The rocket simply cannot carry a compartment with an arc length of 100 meters.
Raw materials can only be transported into space and then processed in space.
Space processing, both domestic and foreign.
Prior to this, there was no relevant experience.
The previous space station was also a combination.
But between the various cabins, there are relatively mature individuals.
Even between each combination, there is its own dynamic.
"I'll solve the problem of the vacuum weightless laboratory for you."
Zhang Xingyang did not quarrel with the other party, as long as it was the equipment or laboratory needed for the R&D process.
Zhang Xingyang was directly approved.
As for how much it will cost, it is already something that does not need to be considered.
At a time when many countries thought that they were developing space weapons at home.
The nation took the opportunity to announce that we were building the largest space station ever built.
All countries are welcome to participate in the peaceful development of space resources.
Although the formal cooperative construction project has not yet passed even one.
However, the funds of various countries have been like sharks smelling blood, and they have been frantically remitted into the officially announced fund accounts.
And there are no strings attached to these funds.
Just begged the Dragon Kingdom not to leave them behind in the next space development.
The royal family from the desert oasis is even crazier.
Directly and wildly invested 10 billion dollars.
There are no other requirements, just to be able to do it after the construction is completed.
Let them go up and have a fun and take a tour.
Zhang Xingyang was stunned by their fanaticism.
At that time, I couldn't help but complain, the big dog is really stupid and has a lot of money.
So now, money really isn't the thing that's holding the project back.
There are at least more than $20 billion in funds lying on the back of the special fund account.
And if the money is spent, as long as Zhang Xingyang blows a little wind, a lot of hot money will be able to pour in.
Of course, they will not lose so much money.
After the big dog investors invested tens of billions, the value of their national funds soared instantly.
Not only did they not lose money, but they even made a lot of money.
"What equipment is missing, how much money is missing, just make a list."
After Zhang Xingyang finished speaking, his gaze swept over everyone in the auditorium.
"Today we are not only going to determine the next overall construction problems, but also to solve the problems you encountered in the research and development process."
"In a word."
"Lack of money for money, lack of equipment for equipment."
"As long as the progress of research and development is guaranteed, I will solve all your worries for you."
After solving the problems of the Institute of Space Technology.
Zhang Xingyang talked about the next topic.
"The second is the core energy system of Starport."
Just when everyone in the auditorium turned their eyes to the crowd in the center of the first row.
Zhang Xingyang said directly:
"I'm primarily responsible for the core energy system."
"I believe that before this, everyone had some doubts about this."
"Why doesn't our starport have huge solar panels?"
"That's because we're going to be nuclear-powered!"
Zhang Xingyang released the slides behind him at the right time.
It was a photograph of an experimental thorium-based molten salt reactor in operation.
Zhang Xingyang turned his head, looked at the smaller experimental pile and said:
"This is the fourth generation of nuclear reactors that we have just successfully developed, using thorium-based molten salt as nuclear fuel."
Spacecraft are powered by nuclear power, but not a small number of them.
The Institute of Atomic Energy has previously developed related isotope thermal batteries.
But an entire nuclear reactor is directly used as the power source.
But it was stunned by the jaws of the crowd.
Because isotope batteries only use isotopes to generate electricity, the power is actually very low.
It's just that it can last for a long time, and the service life can even reach decades.
The power of a nuclear reactor can reach millions of times that of an isotope battery.
The mass of an isotope battery is only tens of kilograms, and the power is only tens to hundreds of watts.
The power of thorium-based molten salt reactors is at least in the megawatt range.
The difference between the two sides is six orders of magnitude.
"Thorium-based molten salt reactor has been successfully developed?"
"Didn't we just put the third-generation reactor into commercial use?"
"The state has done a really good job of secrecy, and I haven't heard any news about it."
Everyone in the audience talked one after another.
Most of them are leaders of major scientific research units, or actual leaders.
"Many of you should be well aware of the situation of thorium-based molten salt reactors"
"If there is anything unclear, let's get to know each other, and I won't go into too much detail."
Zhang Xingyang did not explain the basics of thorium-based molten salt reactors.
Instead, he talked directly about the current R&D progress.
"We have completed the construction of the experimental reactor, and so far the experimental reactor has carried out a total of five test runs, all of which have been successful."
"The current maximum run time is 168 hours."
"While we're sitting here, the sixth test run is still underway."
"This trial run will last at least a year."
"In addition to this, the initial development of a marine-type molten salt reactor has also been completed."
"The first one will be applied to the 240,000-ton ultra-large container ship manufactured by Jiangnan Shipyard."
"Paired with the thorium-based molten salt reactor, it will be our latest supercritical carbon dioxide generator."
"Everyone is well aware of the nature of the molten salt reactor, so even if it is nuclear, its safety can be guaranteed."
It has experienced the blow of the successful development of four generations of reactors.
For marine molten salt reactors, the success of supercritical CO2 generators.
There was not much reaction.
The crowd was now feeling numb.
Even Zhang Xingyang suddenly announced that he had successfully developed nuclear fusion technology.
Everyone here is probably not too shocked.
"However, for the safety of the construction of the starport, the reactor will have to undergo detailed tests on the ground before it will be officially installed on the starport."
Zhang Xingyang finally said.
Even though molten salt reactors are safe, there are still risks.
Especially in space, because the density of matter is lower.
In the event of a leak, it is difficult for the high-temperature molten salt to cool down quickly.
Cooling is easily achieved on the ground, mainly by thermal convection.
But in space, heat dissipation is mainly done through heat radiation.
The cooling efficiency of thermal radiation is extremely low.
Therefore, after the leakage, the high-temperature molten salt will remain in a fluid state, which will continue to cause great damage to the starport.
These must be prevented in a way that can only be done on the ground. (End of chapter)
