From all-round academic master to chief scientist - Chapter 489 The Sky Chariot Lands

“Oh my god, how on earth did this kind of thing get to heaven…”

At the headquarters of NASA, all the staff present were looking at a satellite image that could be included in many science fiction blockbusters on the big screen in front of them.

In the darkness in the distance, a super aircraft full of science fiction was seen floating in the virtual space. At the same time, its speed was obviously increasing, and it looked extremely amazing.

However, although its speed was increasing, they did not see any eruption of tail flames at its tail.

According to common sense, this is completely impossible!

Without the ejected working fluid, where would the driving force come from?

The spacecraft can continuously accelerate in the universe, relying on the working fluid that is constantly ejected, just like the airplane can fly on the earth, relying on the ubiquitous air.

This is Newton’s third law of interaction!

However, why didn’t the giant thing in the picture in front of them eject working fluid?

Could it be that it is a propeller without working fluid?

But how is this possible!

Using a fluid-free engine to propel such a behemoth is simply more outrageous than a Hall thruster.

Although humans have successfully developed a propellant without working fluid, the thrust of that propellant is simply pitiful, and it is impossible to use it on the thing in front of you.

So, what kind of engine does this huge aerospace plane use?

All NASA members present, whether scientists or managers, found it very difficult to understand.

The president was also here. After learning about the matter, he rushed from the White House to the NASA headquarters without stopping, because here they could see the giant thing flying into the sky more clearly.

And he didn’t know what the lack of tail flames meant. He just frowned and turned to look at Eisenberg, “Director Eisenberg, I want you to come up with a plan to deal with this Chinese air force within today.” Is there any problem with the technical analysis of the spacecraft?”

Eisenberg recovered from the shock. After hearing the president’s request, he quickly said: “Mr. President, this… I think we may not be able to do it yet.”

“Can’t do it? Why?” The president immediately frowned, “They have already launched it and showed it to us with great fanfare, but you still can’t analyze the technology they have mastered?”

“No, Mr. President, please listen to my explanation first.” Eisenberg said quickly, and then he pointed to the tail of the Tiannian in the picture, which is the nozzle of the engine.

“Mr. President, please see, there is no tail flame emitted from the tail of this aerospace plane. In other words, its power source is completely beyond our imagination. According to the several future aerospace engines I know, , there is only one that can do this, and that is the fluidless engine.”

“The working medium-free engine uses microwaves for propulsion, so it can achieve the effect of tail flame propulsion.”

“Judging from the current situation, they may actually achieve this kind of propulsion without working fluid.”

When he said this, Eisenberg still couldn’t believe his words. How could that Lin Xiao create a propellant-free propulsion?

This is not scientific at all!

At this moment, an important NASA scientist next to him suddenly said: “Director Eisenberg, there is another possibility, which is a nuclear fusion engine.”

“A projectile is created by throwing in a mixture of deuterium and tritium gas, and then uses a strong laser to cause it to produce an explosion of uncontrollable nuclear fusion.”

“Nuclear fusion explosions are inherently invisible and colorless. If it were on the earth, it might cause phenomena such as mushroom clouds due to evaporation of water in the air and dust on the surface. But in the universe, without these things, it would be completely possible. Made it happen!”

“Impossible, this is even more impossible than propellant-less thrusters.”

However, after hearing the scientist’s guess, Eisenberg waved his hand and said, “Have you never considered how strong the materials are to be able to withstand such frequent small hydrogen bomb explosions?” ? Even carbyne sulfide can’t do it.”

“Not to mention the price of carbyne sulfide, do you think they can pay tens of millions per gram to build something that looks like it must weigh at least a thousand tons?”

“It’s just a guess,” the scientist explained.

“Okay.” Eisenberg shook his head, then looked helplessly at their respected Mr. President, and said: “Mr. President, you also heard that there are only two possibilities now, no matter which one they are. , are all unimaginable to us today.”

“And it’s not just this. You must also have seen the disc structure protruding from the middle part of this aerospace plane.”

“According to my speculation, that probably means that they even installed a controllable nuclear fusion reactor on this aerospace plane.”

“This also means that they can even install controllable nuclear fusion on airplanes that we have not yet achieved!”

“How on earth did Lin Xiao fit a controllable nuclear fusion reactor into such a narrow space? This is as impossible as if they were using a nuclear fusion engine!”

“That’s why I said, I’m afraid it will be difficult for us to fulfill your request.”

Eisenberg smiled bitterly: “That’s completely beyond our imagination.”

Hearing Eisenberg’s words, the president frowned tightly, and then said seriously: “I don’t care about this kind of thing, I only look at the results, not today, right? Then I will give you two more days, the day after tomorrow Before that, I have to see your analysis results!”

“Otherwise…” the president snorted coldly: “You can make up your own mind!”

Eisenberg and others suddenly felt a headache when they heard that the president asked them to do whatever they wanted.

What is this all about?

He made it very clear that they couldn’t analyze his technology at all. Can this situation be solved by just looking at it?

What can they analyze? They don’t know the materials, the structure, and the technology. Their own aerospace aircraft research has always been stagnant due to funding reasons.

But for the president, he didn’t care about these things. He took one last look at the people present and said: “No matter what, I don’t want anything that may affect our landing in four months’ time!”

Anyway, in two months, a new person will stand in front of Capitol Hill, press his hand on the Bible, say “God bless America”, and then take his place.

Now, he won’t care so much anymore.

Then, he left here directly. As for the Tianchaan number, he no longer wanted to look at it anymore, because the more he looked at it, the more annoyed he became.

After seeing the president leaving, the people present cursed in their hearts, and then they were no longer in the mood to continue watching, and honestly began to analyze the aerospace plane.

…

No matter what the situation on the earth is like, Tiannian continues to float in the orbit of the earth.

In addition to its own aerospace engine, the Tiannian is also equipped with ten Hall thrusters.

The Hall thruster is a relatively special thruster that mainly uses xenon gas as the working fluid. After ionizing the xenon gas, it is erupted through an electromagnetic field to form thrust.

Its biggest advantage is that the specific impulse of chemical thrusters is many times greater than that of ordinary rockets. That is, it can provide stronger power for the same mass of working fluid.

However, the problem is that the amount of working fluid it can eject per second is too limited. Chemical fuel can eject hundreds of kilograms of working fluid per second, thus bringing extremely strong thrust.

The Hall thruster can only eject a pitiful amount, and the thrust it can provide cannot even reach the level of a hundred newtons. Compared with the thrust of a rocket engine, which is measured in units of thousands of newtons, it is really a bit shabby. .

However, despite this, Hall thrusters are still widely used on spacecraft. For example, China’s Tiangong Space Station has four Hall thrusters with a thrust of 0.08N, which together can provide a thrust of 0.32N. .

This thrust is obviously very small. On Earth, it is only equivalent to the weight of an object of 32 grams.

However, in the universe, since everything is in a state of weightlessness, no matter how small the force is at this time, it can push something weighing 10,000 tons.

Therefore, the Tiangong Space Station can correct its orbit through these four Hall thrusters, which together can only provide 0.32N of thrust.

As for the thrusters on the Tiannian, after so many years of technological innovation, the thrust they can provide has been greatly increased. In addition, it uses room-temperature superconductors to provide electromagnetic force, so each of them has a thrust of All up to 25N!

25N is more than three hundred times the thrust provided by the Hall thrusters on the Tiangong Space Station, and ten Hall thrusters can provide a total thrust of 250N.

This kind of thrust is obviously not worth mentioning for the two-thousand-ton Tianan, but it is enough to allow it to correct its orbit.

So just like that, Tiannian continued to move towards a higher orbit.

Its hugeness is tantamount to the feeling of blocking out the sky and the sun to other things like satellites floating in the universe, just like the huge starships seen in movies that stretch across the starry sky.

After all, you must know that the heaviest satellite in human history, Skylab 1, which was originally launched by the United States, weighed 76.5 tons and was about 36 meters long. However, such a big guy, in front of Tiannian, Just a little one.

The International Space Station is relatively heavier, weighing 419 tons, 110 meters long and 88 meters wide, which is very huge.

Even the Tiangong Space Station is a bit inferior, because the maximum weight of the Tiangong Space Station is only 180 tons.

Therefore, the International Space Station is the heaviest man-made object in the original starry sky.

The people working on the International Space Station think so too.

Until they saw the giant thing flying gradually from the surface of the blue planet.

On this day, the seven astronauts on the International Space Station looked through the portholes in a daze at the giant thing passing by in the distance.

This giant thing is 125 meters long and has a wingspan of 110 meters.

The three characters [天辇号] written in block letters on it were also clearly visible to them.

“Gift crab!”

A scientist on the space station couldn’t help but express his shock.

And a person on the other side couldn’t help but said: “Is this…the legendary Leviathan beast?”

“What have the Chinese people created?”

They were all shocked by this thing.

Are they a space station or is this thing a space station?

Moreover, their space station was not launched at one time, but was formed after assembly. However, it flew directly from the earth, and it could even go back after a trip to the sky.

Therefore, at this moment, they even felt a sense of envy in their hearts, and even thought about whether to let this behemoth connect with them.

But after looking at it, I found that their space station is so big and their space station is so fragile. It will really be “impossible to fit it in, no matter how hard you think about it.”

Therefore, they could only give up this idea, and then watch this behemoth leave and fly towards a farther orbit.

The orbital altitude of the International Space Station is about 345 kilometers, while the Tiangong Space Station is at an altitude of 400 kilometers.

Therefore, after passing the International Space Station, Tiannian will go to meet Tiangong next.

In the Tiangong Space Station, the three astronauts who had been waiting for a long time had the same reaction as the astronauts on the International Space Station when they saw the giant thing emerging from the darkness.

“Fuck!”

“Isn’t this too awesome?”

“Is it really that big?”

How great would it be if their Tiangong Space Station was as big as this?

In this way, they were in a daze for a while. It was not until the Tiannian was very close to them that they came back to their senses. Then they immediately took out their mobile phones and started taking pictures.

Unlike the people on the International Space Station, they had received the news and knew that the Tiannian was unmanned, so they did not think about contacting the Tiannian. Taking pictures was their political mission. When the time came, they would take the pictures. Photos and videos can be sent back to Earth and used for publicity.

After all, of course a photo of such a domineering Tiannian must be taken, especially from their perspective, it must be a masterpiece.

The Tiannian is also very cooperative. Under Xiaomi’s control, the Tiannian is different from the previous time when it passed the International Space Station and just passed by far to avoid being seen too much. But now in front of my family, it is not so It was so easy to say, so I just passed it from a distance of fifty meters away.

Others may not know what it feels like to fly past a giant object that is more than 120 meters long at a distance of fifty meters, but now to the three astronauts on the Tiangong Space Station, they know it.

It was like a feeling of being blocked from the sky.

Even at the beginning, they were worried that the Tiannian was going to hit them.

It wasn’t until the Tiannian flew over that they relaxed in their hearts. Then they took out the photos they had taken and were shocked.

Imagine what it would be like to fly past a huge thing from the lonely universe, and their photos reflect this feeling very well.

“This is really, really spectacular!”

“Yes, and didn’t you say that the Tiannian uses intelligent driving? This intelligent driving is so powerful that it almost missed us!”

“Yes, I really hope that next time I have the opportunity, I can go inside and take a look.”

At this time, the leader of the three astronauts said with a smile: “Okay, let’s not think about this matter for now. Let’s send the photos and videos back as soon as possible.”

After hearing the captain’s words, the other two team members responded: “Yes!”

Then, they quickly went to the control station and contacted the ground.

So, about two hours later, of course, the next morning came on earth.

CCTV News also posted a video and several photos on major platforms at 8 o’clock in the morning, with the text: “The chariot is coming from the sky, the universe is the road, the starry sky is the scenery, and it is an eternal moment.” 】

The video was naturally recorded from various angles by the three astronauts on the Tiangong space station.

Fifty meters away, a huge object flew by, especially with the universe as the background. Just looking at this picture is enough to make people amazed. And in the video, there is background music, and the sense of majesty in the background music is… In just a short time, the overall atmosphere rose by several levels.

As a result, netizens were all excited.

“Oh my god, isn’t this too domineering? How did such a big thing get up into the universe? 』

“Awesome!” I hope that one day I can go up there and sit.”

“The universe is the road and the starry sky is the scenery. I love this caption. I love it.” 』

“I heard that there is a huge commotion abroad. Everyone is envious of us for having such an awesome super spaceship.”

“My cock is bursting, my cock is bursting!” 』

“Hahaha! Foreign people need to use special effects to shoot this scene in movies, so we can directly shoot it on location! Who else is more awesome than this? 』

…

Netizens were all excited.

In the past year, Americans have wanted to land on Mars, which makes them envious and helpless. They want to land on Mars and conquer another planet among the eight planets in the sun, but they can only be between the earth and the moon. Take a look around.

But it’s great now. They all have aerospace planes, but they can still only use ordinary rockets.

Look, their aerospace plane is so awesome, so big and spectacular, it looks like a starship when it flies over it.

This can be regarded as a comeback. Even if the Americans really get angry, they don’t have to envy them.

It’s hard to say which one is more awesome.

However, at this time, another piece of news came.

Tiannian will land on Earth at 6pm today.

As soon as the news came out, it immediately attracted the attention of countless people.

It took off, but what about landing?

It is not easy to land thousands of tons of things.

At this time, some foreign media began to advocate that there would be problems if the Tiannian landed.

These comments include, but are not limited to, that after landing, the Tiannian will fall apart on the spot due to the impact of the landing; or that after landing, there will definitely be a lot of internal parts that malfunction and require emergency repairs.

What’s more, they called the first flight of the Tian Nian a victim of a political mission, and claimed that all the pilots on the Tian Nian would become victims because of this potentially failed mission.

However, this statement was quickly slapped in the face.

Dingguang Aerospace Research Institute specially applied for an official title, and then announced that the first flight of Tiannian will completely use artificial intelligence driving system to perform all aerospace missions, so even if an accident occurs, there will never be a risk to life. .

This claim quickly caused many foreign media to lose face.

There are quite a few media outlets claiming that a safety accident may occur during the landing of the Tiannian, resulting in the death of the pilot. Anyway, as long as you add “possible”, everything will be fine. There are even many media outlets who even make serious claims about it. How many people are on board the chariot?

As a result, now, not only have their news been completely exposed as lies, they have even been technically discredited. After all, they are using an intelligent driving system!

From takeoff to orbit, everything is actually done by artificial intelligence.

This once again surprised the whole world.

Can artificial intelligence actually do this?

Of course, for those foreign media, they don’t care so much. Since they have been embarrassed, they will increase their cynicism, saying that artificial intelligence cannot make Tiannian land smoothly, and in the end, it will definitely be destroyed by the collective destruction of intelligence. This is the road.

In this way, in just a few hours, there was an uproar at home and abroad over whether the Tiannian could land safely.

And it was in the midst of this quarrel that at an altitude of more than a hundred kilometers, the Tiannian finally left the orbit and began to head towards land.

Because of its wings, Tiannian will not be like a meteorite or a return capsule, which will generate extremely high temperatures on the surface due to violent friction with the atmosphere when it stalls and descends.

Relying on the wings and the speed during landing, Tian Nian smoothly passed through the mesosphere from an altitude of more than 100 kilometers, reached the stratosphere, and descended to an altitude of 10,000 meters.

During the descent, Xiaomi also controlled Tiannian to complete the process of switching from aerospace engines to aerospace engines.

At this time, the Tiannian was over the Pacific Ocean.

Next, it flew towards Asia, towards Beijing.

As the Tiannian arrived on the mainland, many people on the ground could see the huge fuselage as long as the weather was clear and cloudless.

And everyone who sees and recognizes it is extremely excited, and then takes photos and posts them online to share this joy with others.

However, at this time, everyone also knew that the Tiannian was back, which meant that it was about to land.

So, can the Tiannian land safely?

At this moment, people all over the world are turning their eyes over, waiting for the answer to be revealed.
