The solar system is broken

Flat grassland and wide space.

The bright sunshine shines on the tips of the tender green grass. The grass is full of crystal dew, which refracts the sun.

The birds slowly stopped on the unusually peaceful land, swaying their fat bodies and looking for food on the grass.

The blue iron door creaked, and the birds were shocked and flew high.

A group of people behind a high fence.

The writer looked at this big guy with a cold look in his eyes, "Is this?"

"Accelerator!" Dora pressed her hand on the railing, her eyes full of enthusiasm.

This is a big silver-white guy, leaning there in gratitude.

It's a bit like a dial, but it has an extra round tube-shaped outlet and is covered with film.

It looks a bit like an upright hair dryer, the bulge is a bit silly.

A huge pendulum, holding something like a rocket on it, I don't know what it is.

"accelerator?"

"Um?"

Swing the rocket through the arm swing, accelerate it to a certain extent, and use extreme linear speed to throw the rocket out.

But why does this thing look so unreliable?

"Are you sure this thing can work?" The writer looked at Dora suspiciously.

Basically, rocket launches are propelled by solid fuel, and it makes sense not to use this yo-yo method.

Take aerospace as an example. Spacecraft generally use vertical launches. For astronauts, the effect of gravity is only one-way.

This kind of swing arm accelerator, with its rapid swing and crazy switching between weightlessness and overweight, will directly kill people.

If there were no new load-carrying device, the astronauts would definitely chase the designers.

From one aspect, it can be seen that this thing is not very reliable.

"Yes," Dora nodded.

"Don't you need a high-power engine?"

Such a huge arm swing force cannot be satisfied by ordinary engines.

"We used dozens of engines and transferred them to the swing arm through precision transmission."

Dora disagreed.

This... is entirely based on quantity.

The writer suddenly remembered the large transport aircraft T12 as soon as he entered the door, with its huge strip-shaped fuselage.

"Wouldn't you be the same on that plane..."

"Well, one propeller and four engines!"

"Like~" the writer took a breath of cold air.

Is this thing worth manufacturing? It has a take-off weight of 12t?

"So..." The writer glanced at the ridiculously thick arm, and he had a bad feeling.

"Also, a large amount of special steel is superimposed."

Dora nodded matter-of-factly.

The writer's eyelids twitched. What kind of technology was this? It was all based on quantity.

"Then what's the difference between you and private companies?" The writer looked contemptuous.

As we all know, private aerospace companies on Blue Star generally have low technology and rely entirely on accumulation of numbers.

"We do it officially." Dora replied shamelessly, without the shame of a technician at all.

"..."

"That rocket is..."

"Filled with liquid fuel, coupled with a two-engine column."

As soon as you hear the name, you know that this thing is not very high-end.

A bodyguard came out of the hallway behind him holding several headphones and distributed them to everyone.

Dora took an earphone and put it on the writer, and the writer lost his hearing.

All you could see was Dora opening her mouth and speaking some silent words, as if the movie had been muted.

"Huh?" The effect of this earplug is very good.

"Zizzi~" The sound of electricity came from the earbuds.

"The tower is ready~"

It turned out to be the voice broadcast by the launch personnel behind the scenes.

"Engine No. 1 is normal,"

"No. 2 engine is normal."

...

"Engine No. 23 is normal!"

Boy, this is even more outrageous than the writer imagined.

"The rocket steel shell is normal and the fuel is normal..."

The broadcast of the Rockets was too simple, and it seemed like this thing was really a bargain.

This big pendulum has hundreds of millions of points of roughness~

"Boom~"

The man standing on the high platform had his gums shaking and his front teeth colliding with each other, making a crunching sound.

Everyone could only open their mouths slightly to escape from the terrifying sound.

The turf shook and cracked inch by inch. It was like chapped skin, cracking bit by bit.

The exposed gray-white cement land.

It turns out that in order to stabilize this huge piece of grass, the entire grassland was poured with cement, and fine sand was used underneath to prevent the entire cement base from directly shattering.

The swinging arm slowly made a sharp and rattling sound, carrying the rocket and accelerating bit by bit.

accelerate.

The huge steel frame made a twisting sound.

Through the headphones, the writer can still hear the creepy sound, like the curse of a dying old witch.

The rocket went faster and faster, turning into an afterimage.

The vibrations on the ground became more and more obvious, and the high platform also swayed slightly.

The turf near the accelerator was blown away by the wind brought up by the swing arm.

"puff!"

Suddenly there was a crisp sound, and the rocket's coating tore off and disappeared.

Then the swing arm slowly slowed down, and the steel shell gradually stopped shaking.

"The rocket escaped successfully!"

"Highly normal."

"The flight attitude is normal."

"The speed is normal."

...

"Thrusters on!"

The headset did not stop broadcasting.

The writer took off his headphones and rubbed them vigorously. It hurt.

"What the hell is this Dora?" The writer bets that there is absolutely no one in this rocket.

"It's a gadget, a rocket, that's what I can call it now."

This thing is not even a missile.

The difference between rockets and missiles is not big in the eyes of ordinary people, but there is still a big gap in the eyes of professionals.

The difference between guided rockets and missiles is roughly equivalent to the difference between apes and humans.

The biggest difference between simple guided rockets and missiles is the control system. The missile has an autopilot and is controlled full-time. Once launched, the missile always flies under the control of the guidance system.

Simple guided rockets do not have an autopilot, and the control system is very simple. You only need to set a few nodes in the middle of the ballistic trajectory to correct the deviation and control the flight trajectory. The rest of the time it will fly ballistically.

Therefore, the cost is relatively low, but the accuracy is low.

The rocket now launched by Dura only has a single control system, and with a crude steering engine, its accuracy is very impressive.

"Is there something wrong with your rocket thrusters?"

"Um."

In fact, it is not difficult to understand. Using such a large accelerator to throw a rocket several kilometers away and then ignite it to take off is to reduce the burden on the engine.

Carry less dye and fly farther.

"Is this how your aerospace industry develops?" The writer was a bit incredulous.

"Actually, it's not difficult to send it to the sky," Doula said calmly, looking at the people who were actually clearing the turf and checking the launch device, "Just use more engines and more fuel."

"What's more, the first cosmic speed of Muma Star is much smaller than that of Blue Star, so it is easier to achieve."

"But..." Dora paused, "This makes no sense."

There are differences in technology. If we continue on this path, aerospace will always be on a wild road and never look back.

Dora looked very lonely. He had started researching aerospace very early, but he lacked a strong industrial foundation.

This requires dozens of departments, thousands of related majors, and nearly 10,000 supporting enterprises to complete.

There are only 500 enterprises in Youzhou, half of which are in light industry.

Coupled with the problems of raw materials, technology, talents and funds, the development of the entire aerospace industry is as slow as a snail, but it is extremely expensive.

The future of aerospace is now bleak.

"Achieving the goal is a good thing~" The writer doesn't care, it doesn't matter if it's rough or something, as long as it can be used.

"Haha~" Dora smiled.

Moss walked down the platform to the grass and talked cordially with the scientific researchers about the entire launch-related issues.

The accompanying bodyguards immediately followed, leaving the writer and Dora alone on the high platform.

"Have you ever thought about launching space probes, spacecrafts, and satellites? What are we going to do?"

Dora nodded, "I don't know, but people always have to take a look at the thing above their heads."

"This is called the desire to know."

"That radio wave you mentioned last time?" The writer carefully reminded Dora, "You should think clearly about what this means!"

Dora nodded, "Yes, I have thought about it for a long time."

He raised his head and saw the sun shining on his face, making it a little cold.

"Nothing." His tone was light, as smooth as drinking water.

"Space is like Pandora's box. Once it's opened, there's no way to close it," the writer warned Dora, and it was still too late to turn back.

"Curiosity drove me to open him, even if it means paying the price."

The writer looked at this strange scientist and said nothing. He knew that there was no way to stop this.

Civilization is too lonely. A signal will cause the soul to throb, and this impulse cannot be restrained by reason.

The launch pad is normal, except for a small distortion, which does not affect its continued use.

The next step is to wait patiently for the launch report.
