Black technology: I have a refitting factory

More than a month later.

The vacant lot next door to the R\u0026D center.

"Are you ready? Ready, I'm about to start broadcasting?"

He Chao looked at Su Qi and Shi Zhenjin in the distance.

"alright!"

Shi Zhenjin gave He Chao an OK gesture.

"I wonder what the special effects will be like this time?"

He Chao was looking forward to it.

In order to keep it fresh, he did not experience it in advance, but planned to experience it temporarily with the audience so that they could have the same feeling.

Then, he opened the live broadcast room.

As soon as the live broadcast room opened, many people poured in instantly.

"Building a space drone in just one month, Lord Up, is this too much?"

"I'm here to see the special effects!"

"Even though I know it's a special effect, it's exciting to think about going to outer space."

"Anchor, please be more professional this time, otherwise you will be exposed immediately."

…

One barrage after another basically questioned He Chao.

People who felt that the ghost drone was real before are now speechless. It is too exaggerated. If a space drone is released in a month, the ghost drone in front may be a show effect.

"Welcome to the live broadcast room. You see the drone over there. Isn't that shape cool?!"

He Chao did not respond to the barrage, but turned the camera to focus on the drone in the distance.

That's their model, and it's replaced with special effects when it takes off.

"It looks cool, but how can it fly?"

"Master Up, I'm afraid you don't know how much energy it takes to go to outer space. You're such a little kid, you can fly 30,000 meters, so I'll write my last name backwards."

"Do you dare to be more careful?"

…

When the camera turned to the drone, the barrage exploded again. In everyone's perception, flying into outer space requires carrying rocket fuel. Based on the current principles of aircraft flight, it is impossible to fly without the atmosphere.

Speed ​​is also difficult to achieve.

"I'm knocking on the blackboard. I am a high-tech master. Is it appropriate to take the ordinary route?"

Seeing the content on the barrage, He Chao became happy. He was about to do special effects. Who would play rocket launch with you?

Doesn't that seem too low-level?

After once again causing a wave of live broadcast popularity, he said again,

"As usual, let me introduce to you the contestants who will appear this time. This drone is, no, it is a space fighter. The engine of this drone is a plasma engine.

This engine requires only a small amount of air to produce a large amount of power. Therefore, the things you question are meaningless. If you want to be a space fighter, you can't take the usual path. Everyone can take another look. The shiny alloy on the outside is a kind of low light weight and high heat insulation..."

Just when He Chao introduced the drone.

China Aviation Third Research Institute.

A conference room.

At this time, the conference room was full of people.

Everyone gathered here not for a meeting, but to watch the live broadcast.

Ever since they learned that Professor Wan planned to watch the live broadcast of a black technology up master, everyone else became interested. Before the live broadcast started, we simply found a conference room and everyone watched it together.

"This up owner still has something. According to what he said, it can indeed be pushed out of outer space without a rocket."

An old man in his fifties smiled and said to Professor Wan.

He is the director of the research institute and his name is Qi Youwen.

"Yeah, I still did my homework. Unfortunately, this plasma engine technology is not mature yet. It can only work after it reaches space. The thrust generated now is too small, let alone such a big one. Drone reaches first cosmic speed.

Even if it were half smaller, it would be impossible. "

Professor Wan nodded.

Plasma engines are also being researched in China now, but this thing! It's not ready to be used.

"The design idea of ​​high heat resistance is very advanced. I feel that we can research in this direction. Hahaha, I didn't expect that I can gain something from watching a live broadcast."

Qi Youwen smiled.

"The special effects of this up are good. Doing more live broadcasts of black technology in aviation can actually advertise our aerospace industry, and more people may choose to become astronauts."

Professor Wan said, “It’s about to begin!”

Everyone's eyes turned to the screen again.

"All pre-inspections have been confirmed, now we are ready to take off! Three! Two! One!"

After He Chao finished counting down, he pressed the takeoff button.

Buzz!

Blue flames spurted out from the bottom of the drone, and the drone plucked onions from dry land and quickly rose into the sky.

After reaching a certain height, the direction of the engine was changed.

boom!

After the loud noise, a strong wind blew across the earth.

At the same time, He Chao's hair was blown up by the wind, revealing his high hairline.

"I really know how to play, and even made a fan to blow my hair..."

Looking at the fan placed by Shi Zhenjin on the ground in the distance, He Chao had a black line on his face, which ruined his image!

The drone was getting faster and faster, and suddenly the camera captured a cloud of white mist appearing around the drone.

"Sound barrier, have you seen it? When it is close to the speed of sound, a barrier will be formed. Everyone, watch out, the sonic boom is coming soon! Cover your ears!"

Shi Zhenjin said excitedly.

Sound barrier, he had seen this thing in many videos before.

But this is the first time to experience this kind of first-person perspective!

Although it is a special effect, it is also very exciting.

boom!

A loud bang resounded throughout the sky.

Only a slowly drifting sonic boom cloud was left at the tail of the drone.

"Come on, the audience who questioned my speed looked over. Did you hear this explosive sound? This is the sound of breaking the sound barrier, and the sonic boom cloud behind me. The speed is only the speed of breaking sound in less than a few minutes, and it's still Keep improving!"

He Chao is full of confidence, and the special effects produced by Su Qi are really awesome and invincible.

The special effect that broke the sound barrier just now was impossible to tell whether it was real or fake.

"It has flown out of the stratosphere. You can see this layer, which is beyond the height of the aircraft. There is a balloon over there. I will take you to see it."

Seeing a balloon appearing not far in front of the drone, He Chao quickly controlled the aircraft and flew over.

"To give you some popular science, this is a weather balloon. It usually flies at an altitude of 25 kilometers above the ground. There are instruments hanging on it to monitor the weather. Let's take a look. The number of this balloon is 17Z..."

…

"Lao Wan, this special effect is really good. If it were released directly and said that our country has developed a new type of aircraft, foreign countries would probably believe it."

Qi Youwen joked, "When I was looking at the weather balloon just now, I looked at the speed, position parameters of the drone and the corresponding scenery based on its speed, longitude, latitude, altitude and the position of the moon. , are consistent.”

"Everyone should have calculated it!"

Professor Wan laughed.

As an old astronaut, these are the things they have done the longest.

Especially when encountering this kind of situation, I will be itchy to calculate the rationality, and the result seems to be correct.

"But it's a pity that there are still some flaws. As for the one that turned around just now, at such a high speed, there should be no material that can withstand the pressure."

"Don't ask for too much."

Qi Youwen smiled and said, "Keep watching, we are about to exit the Karmen line."

The so-called Karman Line is the theoretical dividing line between outer space and the atmosphere. Above this orbit, it is impossible for any aircraft to fly with the help of air. It must exceed the orbital speed to prevent it from falling.

Those that can fly beyond the Kármán line are called aerospace, and those that cannot fly are called aviation.

Just when everyone was excited to see what other tricks He Chao could create.

Buzz!

Buzz!

Qi Youwen's phone rang.

"Huh? What, something went wrong on an outbound mission and I left the space station?!"

After listening to what was said on the other end of the phone, Qi Youwen stood up, his face wrinkled into a bitter melon suit, "Okay, yes, I will convene people to analyze the plan immediately."

"Stop watching the live broadcast, there is an extremely urgent mission!"

Qi Youwen turned off the live broadcast projection and looked at everyone present with a serious face.

"What's wrong?"

Professor Wan looked at Qi Youwen.

"When the space station was performing an outbound mission, something went wrong. An astronaut accidentally flew out while out operating."

Qi Youwen said quickly.

"Didn't we have seat belts before?"

Professor Wan raised his eyebrows.

"It just happened that here, a piece of debris from a satellite floated by, cutting the safety belt, and then the person flew out."

Qi Youwen replied.

"Hiss! Such luck..."

Everyone took a breath.

It is true that there are a lot of debris in the sky, but generally speaking it will not have any impact on space missions. In a situation like today, when I went out to work for a short period of time, I encountered debris and it happened to hit the seat belt.

This probability is higher than the probability of winning the first prize in Shuangseqiu.

Afterwards, everyone felt shocked.

In space, it is very dangerous to break away from the space station. Firstly, it is difficult to dock with the space station. Secondly, the oxygen carried by astronauts can only last for a few hours.

If we can't return to the space station within this time, it's basically hopeless.

"Now we need to find a way to rescue people. Let's put our heads together and think about it!"

Qi Youwen spoke up.

Everyone fell silent upon hearing this.

Space rescue is no different than on the ground and at sea. On the ground and at sea, no matter how you say it, there are aircraft that can reach it, and flying there is not a particularly troublesome thing. But in space, it's different.

In space, changing orbit is a matter of caution.

Moreover, sending an aircraft to space requires a long period of preparation. Under the current situation, there is no way to send an aircraft up immediately.

"Send another person to pick him up. Be careful. There should be a chance."

Professor Wan said.

"Let me ask! Xiaoyou, apply for access to the video in the space station."

Qi Youwen ordered a young man wearing glasses.

"good!"

Xiaoyou nodded, and then quickly operated on the computer.

Soon, a video directly connected to the space station appeared on the projection screen.

"How is the situation? We have a plan here. Send another person out, be careful, and pull the person back."

Qi Youwen said.

"No, because of the impact of the debris, Bi Yufeng has been taken far away. Even if all the ropes on the space station are tied, they are out of reach."

The leading astronaut said, at this time the atmosphere in the entire space station was very heavy.

They all got through the most dangerous time like taking off, but they didn't expect that something would go wrong in this situation.

"Send the micro thruster over and give it a try. Give us the direction and address, and we'll use the computer to calculate the path."

Professor Wan spoke up.

Soon, the other party gave these parameters.

Professor Wan and a group of people hurried out of the conference room to the research center, picked up the parameters and started running them.

The results were not slow in coming.

However, the result was that everyone fell silent.

According to the calculation results, the thruster can send people there, but after sending them there, there is simply not enough thrust to bring people back. This plan won't work!

"Does anyone else have a plan?"

Professor Wan rubbed his forehead. It was too difficult to save people in outer space, especially in this situation. He had already thought of every possible way.

Everyone fell silent.

They have no better way.

In this case, unless drone technology like the one seen in the live broadcast appears, it will be possible to bring people back in space.

But, how is that possible? !

That drone is nothing more than a special effect.

There is still a long way to go before we can actually figure it out.

This time, is it really impossible to recover? !

at the same time.

"We have broken through the Karman line, and this live broadcast can basically be declared a complete success. However, I naturally want to challenge the limit, and I will challenge you to fly side by side with the space station later."

He Chao talked eloquently in the live broadcast room.

This live broadcast has been relatively successful up to this point. The beautiful scenery in space has been simulated so well. Su Qi's technology is enough to be a special effects master in science fiction movies.

The only regret is that there is no plot in this live broadcast and it is a little less interesting.

"As you can see, our current speed is the first cosmic speed of 7900m/s. This speed can keep us at this level without falling. But if we want to fly upward, we have to speed up.

But you still have to pay attention to one thing. When you fly a space shuttle in the future, the speed should not exceed 11,200m/s. It will fly out of the earth by then. "

He Chao said cheerfully to the live broadcast room, "Let's speed up now!"

The height of the drone continued to increase, getting higher and higher.

"Everyone, please pay attention. Our height is rising. You can see the shape of the earth, like a huge gem. I just don't know if there will be a panoramic effect later. Let me explain to you, the so-called panoramic effect. When you look at the Earth from space, you see an interesting bell-shaped horizon. On this horizon, you can see the outline of the entire Earth.

Wait, why is there a person floating in the air over there? ! ! "

He Chao was stunned. On the upper left side of the drone, he saw an astronaut floating alone in the sky.
