This civilization is very strong, but the technology tree is a bit crooked

"This coated battery car trunk?"

"Where's the rocket? Where's my rocket? Where's my big, big, long rocket that shoots?"

"Anchor, where did you hide the rocket?"

"The anchor quickly took out my rocket."

"Damn Rocket, the anchor can at most take out a toothpick."

"Pass it on, the anchor is a toothpick"

Looking at the trunks of battery cars in the square, they are shining in the sun.

Not far away, there are several smart cars that look like courier pick-up robots, carrying new battery car trunks.

The barrage and comments in the live broadcast room made him dumbfounded.

Shouldn't it be said that these are the Starlink satellites that Yifei wants to build?

But, the rocket is gone.

Question, where is the rocket?

Chen Yi noticed the changes in the barrage, turned to the camera and said with a smile.

"It's well known."

"The satellite is as long as the trunk of a battery car, and the satellite does not need a rocket to enter orbit. These are all normal things."

"So you don't need to be surprised by the scene you see in front of you."

? ? ?

Chen Yi's voice fell.

Question marks popped up all over the screen.

Good guy.

How can this satellite go to the sky without a rocket?

Could it be that the Flying Immortal flew up to the sky with a sword, and then sent the satellite into space orbit?

"There is no doubt. From Yifei's point of view, Starlink satellites do not need rockets to go to the sky. This is fundamental."

"The focus of my Yifei live broadcast today is Starlink, which is a satellite. Rockets don't need to leave the country."

"Since the birth of SpaceX's Starlink satellite system a few years ago, this has been a hot topic in global technology."

"Thousands of satellites are above our heads, forming a huge satellite network."

"For these Starlink satellites, everyone has different opinions and debates. Some say they are space junk that crowds the orbit, and some say they are the future of the global communication era."

"Of course, I don't comment on these arguments.

"However, due to some things in the past few days."

"The top of my head has become a satellite nest, and there are at least hundreds of satellites going around my head every day."

"As an anchor who likes to play games and is also good at playing games."

"My thoughts have always been more straightforward, that is, since they are going to hang around my head every day."

"Why don't I build a set of star chains myself and hang around them every day?"

"then."

Chen Yi was holding a mobile camera.

He walked to the integrated satellite in the square, and pointed the camera at a satellite at close range.

".This is the Starlink in front of you, the Starlink satellite in front of you!"

call!

The voice fell.

Chen Yi thought about it.

A gust of air rolled up out of thin air on the ground.

All the satellites ejected glow and air currents, and began to slowly float up.

"The mass is 9.86 kilograms, which belongs to the level of nano-satellites."

"The whole uses the strongest communication module of Yifei, the strongest remote sensing detection module, the strongest main control system, and the latest solar panels."

"Combined with Yifei's latest ion propulsion, an integrated satellite with the ability to independently lift into orbit."

"600,000 kilometers of communication, 3,000 kilometers of remote sensing."

"Whether it's human face images on the ground, or underground mineral resources, meteorological weather in the air, or signal control in space, they can be easily detected and competent."

"The world's nano-satellites are number one, and Starlink satellites are number one. They are worthy of their names."

Nearly a hundred satellites are slowly taking off.

The shiny surface reflects light in the sun.

And Chen Yi stood in the middle of these satellites.

Open your hands and welcome these satellites to rise into the sky.

"Fuck Cao Cao, my wife, come out and see the gods!"

"Mom, this is too fairy-like."

"Make up the trunks of these battery cars and replace them with a flying sword. This is a proper Mahayana-level sword fairy."

"This is a satellite, a satellite! The world's number one satellite! It's not the trunk of a battery car!"

"One thing to say, although the performance of the satellite introduced by the anchor is very good, it really looks like the trunk of a battery car, or a non-mainstream trunk with a flash film."

"No, what kind of trunk are you talking about, haven't you noticed the characteristics of this satellite?

It has the ability to independently launch into orbit!

Independent launch into orbit ah!

This means that as many satellites are built, as many satellites can be sent into orbit.

This is to subvert the entire aerospace industry and the entire history of aerospace! "

"too strong!"

"I just took a look, about 9 minutes, there will be an intelligent robot carrying a newly manufactured satellite out of it.

As we all know, the satellite is controlled by the system to fly into orbit, and the computer system does not need to rest.

This is 60 minutes an hour, 24 hours a day.

160 satellites were launched into orbit in one day.

Starlink satellites are all in low-Earth orbit below 1,000 kilometers.

Satellites at this altitude are short-lived.

Apart from a certain company, few countries have seized these tracks.

But now, according to the speed of the anchor.

In less than a year, the entire low-Earth orbit can be filled. "

"I'm going, doesn't this mean that in the future, if other companies want to launch near-Earth satellites, they need to apply to the host for a position first?"

"You'd better make it clear which company this certain company refers to (dog head)"

Ignore the almost crazy barrage of the live broadcast.

Chen Yi fully noticed the array of parameters projected on the retina by the AR glasses.

These are the process of launching a satellite into orbit, involving some parameters and orbit calculations.

According to the plan that Chen Yi calculated at the beginning.

The entire process of launching into orbit can be roughly divided into three steps.

Lift off, speed up, and enter orbit.

First lift off from the ground, lift off and cross the Karman Line.

According to the calculation of thrust and mass, these satellites do not turn on the afterburner mode, and the acceleration at low altitude is very low.

About only 0.1 meters square seconds of acceleration.

That is, it accelerates 10 cm in 1 second.

The only thing that is great is the durability.

Fully charge before take off.

Charging while flying, this can last for several hours of acceleration.

But because of the design of the aerodynamic layout.

Before breaking through the Karman line, the speed of 105 meters per second is the limit.

That means it will hit top speed in about 10 minutes.

According to calculations, reaching the extreme speed happens to be at a height of 54,000 meters.

After crossing 50,000 meters, this enters the critical space, and the atmospheric resistance is already very small.

According to the process planned by Chen Yi,

At this time, the satellite will turn on the afterburner mode to improve the ejection quality of the ion thruster.

With the help of this atmosphere, the altitude of the propellant can be supplemented, and the speed of the satellite can be increased to 1,000 meters per second before crossing the Karman line at an altitude of 100,000 meters.

Then, the replenishment of propellant is lost.

The satellite closes the air intake, reducing the jet quality and increasing the jet velocity.

From obtaining greater thrust, to obtaining greater specific impulse.

Finally, with the propellant carried, the satellite is pushed to an altitude of 700 kilometers, and at the same time it is accelerated to the first cosmic speed for orbital flight.

But now, according to actual liftoff data.

Chen Yi recalculated the plan based on the seasonal weather, and got a more optimized plan.

"It's summer days, the sun's radiation is more intense, and the solar charging case gets more power."

"The afterburner mode can be turned on in advance to increase the power of the ion thruster."

"In this way, the speed can be increased to Mach 4, 1200 meters per second, before reaching the Karman line."

Determine your own calculations.

Chen Yi thought about it.

Acceleration is always superimposed.

Faster and faster satellites.

There was a sudden pause, and then the speed increased sharply.

Pass through the clouds and enter the stratosphere, where the sun's radiation is more intense

"Fuck, this is Shenda University, we got it! We got it!"

"The satellite penetrated the clouds and began to accelerate into the sky. The attitude is very stable, the flight is normal, and the remote sensing signal is normal!"

The satellite had just penetrated the clouds.

The tracking team at Shenzhen University immediately shouted and commented in the live broadcast room.

They tracked it down.

"This is CUHK, and we captured it too! The satellite is flying normally, and the remote sensing signal is normal!"

"South China University of Technology also took pictures. The attitude of the satellite is stable and everything is normal."

"I see, I see, a large area of ​​shining satellites, Xiamen University's signal is normal!"

"Zhejiang University completed the check-in, the satellite attitude is stable, and the flight is stable!"

"Jinling Airlines captured it"

Because of the early acceleration, in just a few minutes, the satellite rushed to an altitude of tens of thousands of meters.

One by one, the tracking teams of colleges and universities that were not covered by the curve of the earth had already taken pictures of the satellites, and they were excitedly publishing barrage and comments.

Compared with the previous moon landing drones.

This time the satellites were shining brightly, and the difficulty of tracking and shooting plummeted.

"Teacher, this ion thruster is in the atmosphere, and the combustion chamber of the engine is replaced by an accelerating electric field, which can realize the launch of the satellite into orbit."

"Doesn't this mean that ion thrusters are more powerful than chemical combustion engines in the atmosphere?"

"In this way, we also study turbojet, ramjet, what does scramjet do?"

Shao Kaiwang looked at the satellites that were rising faster and faster, feeling a little doubtful in his heart, and looked at the professor who came to watch the live broadcast together.

"This question cannot be explained in a few words."

The professor looked at his proud student, afraid of hurting his self-confidence, organized his words: "The electric field acceleration of the ion thruster is inherently more efficient than chemical combustion.

If the injection quality and injection speed of the ion thruster can be precisely controlled.

At the same time, it solves the problem of high-density electric energy and solves the problem of external screening and supplementation of propellant.

There is also the problem of ultra-lightweight fuselage.

While ultra-lightweight, it can also ensure the high temperature resistance, yield strength and tensile strength of the fuselage.

Solved all these problems.

So what turbojet, ram, scram, etc. that we are studying now can all go into the garbage dump of history.

If there is a problem that cannot be solved.

This ion thruster is far worse than a combustion engine in the atmosphere, and it is not suitable for use in the atmosphere. "

"These wing-flying ion thrusters, these self-lifting satellites"

Shao Kaiwang turned his head subconsciously and looked at a group of satellites in the live broadcast room that had already exceeded the critical height of 50,000 meters.

"Kai Wang, remember one thing, that is a pervert.

We mortals, there is no way to compare."
