It's normal to develop some black technology in the future, right?

Chapter 400: Technology Itself Is Not Uncommon

"But it does not mean that the ground simulation step is 60 points. Every wrong simulation step can get 60 points. In many cases, the ground simulation step is 0 points, and there are many explosions during the launch process.

So there is no standard answer to this question." Chen Yuanguang said.

In the video, the Changkong is already approaching the Guangjia.

“The docking should be completed very quickly because the Light Armor itself is an autonomous driving technology.

To be precise, now more and more docking is done automatically, but ours is considered docking." Chen Yuanguang said.

“Regarding the docking of space vehicles, we just talked about various standards, including the attempt made by American on the Gemini spacecraft.

America was the first country to attempt space docking, while Russia was the first country to attempt automatic docking.

What everyone knows is that they were engaged in the space race at the time, competing for the title of being the first to successfully land on the moon.

Under such circumstances, both Russia's Soyuz 1 and America's Apollo 1 experienced tragic failures. The former crashed directly due to a parachute failure during landing, and the latter caught fire during the testing phase before launch.

All astronauts on both craft were killed.

Under this premise, Damao began to think about whether there was any way to make the aircraft dock automatically, which means complete automation.

They finally succeeded in 67, completing a fully automatic docking at an altitude of 172 kilometers from Earth.

We mentioned earlier that there are international standards. The docking of our country's earliest Shenzhou 8 and Tiangong 1 space station used the APAS standard.

It is also one of the most mainstream standards in the world.

Therefore, when Tiangong is open to the public in the future, spacecraft from most countries will be able to dock with Tiangong under this docking standard and enter the Tiangong.

Having said so much just now, it seems that all the above mentioned are the contributions made by America and Russia in the field of aerospace, but China also has its own contributions in space docking.

At that time, the Chang'e-5 ascender completed ignition and takeoff on the moon, and then successfully completed automatic rendezvous and docking with the orbiter and returner combination in the lunar orbit, and smoothly transferred the lunar soil sample container to the returner.

This event itself is not only the first time that humans have achieved an unmanned rendezvous and docking of lunar orbital spacecraft, but it also uses a completely new docking standard."

"I always fall asleep when listening to the teacher in class, but I enjoy listening to the God of Light's lectures in the live broadcast room."

"The Americans and Russians are still too strong. It's no wonder they are dissatisfied with the current situation since they had this technology sixty years ago. If I were in their place, I would definitely be dissatisfied too."

Lin Jia added: "This time we have gone a step further. Previously, China Aerospace's new standard was only used in our country, and it was not promoted globally because it is difficult for countries to unify the standards for aircraft docking.

Russia and America had the advantage of time. At that time, they were the only two players in the world, so it was easy for them to turn their own standards into international standards through their own efforts.

However, the number of countries that can accomplish space docking today is far less than that of the past, so it is very difficult for the new standard to be recognized internationally and become one of the international common standards.

But this time the new standard we developed has successfully become an international standard. All future deep space stations will adopt this standard and build parking cabins that meet this standard."

The main reason is that Guangjia Aerospace has too much work to do, and any single thing would be enough to be publicized as an achievement by other companies.

In the live broadcast, the Changkong was slowly approaching the Guangjia space station.

The Chinese netizens in the live broadcast room were all very excited, because size is the most intuitive thing.

When the Changkong spacecraft went to the International Space Station to carry out rescue operations, it was obvious that the cabins of the Changkong spacecraft and the International Space Station were about the same size.

Compared with the cabin of the Guangjia, the Changkong is obviously smaller.

This is even when there is a distance, you can still see that it is smaller. What would happen if there was no distance?

"I didn't feel that way before, but now I feel that the Light Armor is so cool."

"It's not that you don't know the goods, it's that you compare them. Compared with the Light Mech, the International Space Station looks so shabby."

"This size comparison is too obvious. If it were a reporter from an official media outlet, they would definitely take pictures of you as a mess."

"Are we going to land on the outer platform? Why is such a large platform not flat but has a few bumps and potholes?"

After seeing the comments, Chen Yuanguang said, “I saw someone asking, yes, the platform is specifically for landing aircraft.

All kinds of aircraft can land on the platform. After landing, they will be retracted and various tasks will be carried out, such as coating and refueling as we mentioned.

An audience member here asked why it is not a flat surface. In fact, we also want to design it into a flat surface so that when there is no aircraft landing, it can be equipped with some solar panels to serve a charging purpose.

But it’s not possible, because there are international standards for the docking or parking of space vehicles.

Previously, when docking through the airlock module, the standard was APAS-75, a standard established when the Apollo-Soyuz space station docked in 1975.

In 2000, a new standard, APAS-95, was introduced, which was the docking station standard in the past few years.

When we were building the APAS-2026, we also communicated with space agencies of various countries. We worked hard for at least two years to formulate this standard, and finally finalized APAS-.

So we call this thing that looks like a platform a dock. This is also the first time that the Chinese have formulated standards for space vehicle docking. In the future, all spacecraft will need to comply with the APAS-2026 standard.

Of course, some people may say that I may have manufactured the aircraft before the standard was established, so how can I comply with this standard?
And before that there was the Guangjia, the International Space Station, and the Tiangong. With so many space stations, the standards should be different. So which standard should I use?

Let me explain here that you should use the standards of the space station you want to go to.

For example, I may have designed an APAS-95 aircraft for the International Space Station before. So when I go to the International Space Station, I don’t need to modify it and can go directly. But if I want to go to the Light Armor Space Station, then I will install a transfer device.

It’s just like when you travel from China to Europe, you have to bring not only the charger but also the charger adapter. The underlying logic is the same.”

At this time, the foreign astronauts and Chinese astronauts on the Changkong had already entered the Guangjia.

After arriving safely on the Light Armor, it can be said that the life-and-death crisis has been resolved. After replenishing energy and completing the painting, you can go back.

All the foreign astronauts who were originally in their positions were eager to go to the front cockpit to take a look at the interior of the Light Armor port cabin through the camera.

"Thomas, it's your turn." The other astronauts all looked at Thomas. This was because Thomas was the only one who knew a little Chinese, and the others could only say "hello" at most.

It is not known whether the Chinese astronaut in charge of piloting the Changkong really does not understand English or is pretending not to understand it. When you talk to him in English, he will pretend not to understand.

"Thomas, tell everyone, now is time to eat and go to the bathroom. If you need it, do it as soon as possible. We will return to Earth after completing the refueling and coating." After Wang Xudong came out, he said to Thomas, asking him to convey his meaning to the other astronauts.

"Wang, can we take a look inside?" Thomas asked earnestly, his eyes full of sincerity.

Wang Xudong shook his head: "No, our most important task this time is to bring you back safely, not to visit the Light Armor."

Thomas said: "We just came here. As you Chinese say, we came when we were called."

"France has a cabin on the Light Armor. You will have many opportunities to travel back and forth here with us in the future." Wang Xudong knew very well what Thomas and the other astronauts meant.

I just want to visit and get as much information about the Light Armor as possible.

Thomas immediately understood the subtext of Wang Xudong's words.

The French will have plenty of opportunities to visit the Light Armor in the future, so why are they in such a hurry? The astronauts from other countries should be in such a hurry.

France has shares in the Light Armor, so we should be on the same front.

The other astronauts felt a little regretful after hearing this, and Megan was even more anxious: "Didn't you tell him that this was a rare opportunity?
Are we just going to sit here and wait for the LightMech to refuel and leave?
It would be a waste of such a long journey.”

Thomas said directly: "Yes, that's what they planned. This is a plan made by the Chinese.

You know, their astronauts need to listen to the ground control center, and they don’t have much autonomy.”

The astronauts sitting in the Changkong could not see the outside scenery, nor did they know how the operations were carried out. They could not even hear the sound of the materials being sprayed because there was no air in the port.

I could only vaguely feel the fuselage vibrating slightly.

On the contrary, the audience watching the live broadcast can see the entire spraying process clearly through the images transmitted back from the camera inside the Light Armor.

The Changkong was parked inside the Guangjia port, surrounded by huge robotic arms. The nozzles on the robotic arms were operating, and one could visually feel that a thin layer of white substance was beginning to form on the surface of the entire Changkong.

"I'm not sure how much the audience knows about spray-on insulation," said Chen Yuanguang.

Lin Jia said helplessly: "You definitely don't understand at all. You treat the audience as beginners who have no idea about this matter."

"Okay, then I need to explain first that any aircraft needs to have a heat-insulating design, because when flying at high speeds, friction with the air will occur, and your surface temperature will begin to soar.

This is especially true for space vehicles that need to leave and return to Earth.

Therefore, space vehicles often have a special thermal protection system. The thermal protection system is composed not only of the thermal insulation layer, but also of the internal thermal insulation effect, because there is a large amount of fossil fuel inside. If the heat is transferred from the surface to the inside, it will explode with a boom.

The idea of ​​using automated equipment to apply a thermal insulation layer to the surface of a spacecraft was also not something that Guangjia Aerospace had completely come up with.

It is easy to imagine this matter, as both America and Big Mao have tried it before.

Even NASA succeeded.

They designed an automated spray system called PAR Systems, but instead of spraying thermal insulation on surfaces, they sprayed thermal insulation on rocket fuel tanks.

(Liquid hydrogen tank just finished spraying through the PAR system)

NASA uses this automated spray system to significantly shorten the process, which used to take months, to just a few days.

More precisely, they shortened the 12-week period to just one week.

But NASA's automatic spraying system is used to spray fuel tanks, most of which are cylindrical.

From a geometric point of view, the structure is simple.

No matter how huge it is, its structure is very simple.

Like the rocket liquid hydrogen tanks that PAR was primarily used for in the past, it is a huge cylinder with a diameter of more than 27 feet and a length of more than 200 feet.

Then they use a special foam material for spraying, which mainly contains two different types of foam materials, and then the automated system inside PAR precisely meters these ingredients to mix the thermal protection material to the exact ratio.

Our automatic spraying devices are similar in principle. They are automatic spraying robotic arms that complete the production of thermal insulation materials according to the composition ratio inside. They are essentially the same.

It’s just that ours is much more complicated, and our spraying equipment can adapt to aircraft of all sizes.

Whether you are a spaceship, a space shuttle, or a possible UFO in the future, the spray device on the Light Armor can add a layer of insulation to your surface.

No volume restrictions.

Another very important point is the choice of thermal insulation materials. We choose composite materials for thermal insulation materials.

The thermal insulation coating is mainly made of high-temperature resistant resin combined with inorganic fillers such as silica and mica powder, as well as some sublimation substances of selenium oxide and mercury sulfide.

However, during the firing process of these coatings, the sublimated substances will evaporate due to the heat, and then the remaining resin will form a microporous carbonized layer.

That is to say, after Changkong returns to Earth, there will be a layer of ugly black substance on its surface, which is the trace left after the thermal insulation layer is consumed.

Don't worry, it can be washed off.

The reason for adopting this design is that, more professionally, we can obtain many of the materials in it on the moon.

In other words, the thermal insulation materials on the future Light Armor will not need to be obtained from the Earth. After all, the distance from the Earth to the Earth is 32 kilometers, and the things we transport over there must be more valuable.

We plan to mine and process raw materials directly from the lunar surface, and then use them directly on the Light Armor as one of the thermal insulation coatings.

The fundamental reason for this concept is to make the best use of existing space resources and reduce dependence on Earth resources as much as possible. "
