"This coated battery car trunk?"
"Where's the rocket? Where's my rocket? Where's my big, thick, big, long rocket that can also shoot?"
"Anchor, where did you hide the rocket?"
"Anchor, quickly take out my rocket."
"You fucking rocket, the anchor will take out a toothpick at most."
"Pass it on, the anchor is a toothpick"
Looking at the pile of battery car trunks in the square, they are shining in the sun.
Not far away, there are several smart cars that are like express delivery robots, carrying new battery car trunks one by one.
The barrages and comments in the live broadcast room made me dumbfounded.
Could it be said that these are the Starlink satellites that Yifei wants to build?
But, the rocket.
Question, where is the rocket?
Chen Yi noticed the changes in these barrages, turned his head to the camera and said with a smile.
"Everyone knows it."
"Satellites look like the trunk of a battery car, and satellites don't need rockets to enter orbit. These are normal things."
"So there is no need to be surprised by what you see in front of you."
? ? ?
Chen Yi finished speaking.
Question marks filled the screen.
Good guy.
How can this satellite get into the sky without a rocket?
Could it be that a flying fairy from outside the world shot up to the sky with a sword and then sent the satellite into orbit?
"There is no doubt that in Yi Fei's view, Starlink satellites do not need rockets to fly into the sky. This is fundamental."
"The focus of my Yifei live broadcast today is Starlink, which is a satellite. The rocket does not need to leave the country."
"Since the birth of the SpaceX Starlink satellite system a few years ago, this has been a hot topic in global technology."
"Thousands of satellites are above us, forming a huge satellite network."
"Everyone has different opinions and debates about these Starlink satellites. Some say they are space junk that crowds the orbit, and some say they are the future of the global communications era."
"Of course, I will not comment on these arguments.
"However, due to some things in recent days."
"The top of my head has become a satellite nest, and there are at least hundreds of satellites orbiting above my head every day."
"As an anchor who likes to make fun of people, he is also good at making fun of people."
"My thoughts have always been straightforward, since they are going to hang around my head every day."
"Why don't I build a set of star chains myself and go around them every day?"
"then."
Chen Yi is holding a mobile camera.
He walked up to the integrated satellite in the square and pointed the camera at a satellite at close range.
".This is the Starlink in front of us, the Starlink satellites in front of us!"
call!
The words fell.
Chen Yi thought.
A burst of air rolled up out of thin air on the ground.
All the satellites were emitting light and air currents, and began to slowly rise to the surface.
"The mass is 9.86 kilograms, which is at the nanosatellite level."
"The overall system adopts Yifei's strongest communication module, the strongest remote sensing detection module, the strongest main control system, and the latest solar panels."
"Combined with Yifei's latest ion thruster, it is an integrated satellite with the ability to independently lift off and enter orbit."
"600,000 kilometers of communication and 3,000 kilometers of remote sensing."
“Whether it is facial images on the ground, mineral resources underground, meteorological weather in the sky, or signal control in space, they can easily detect and perform the task.”
"The world's number one nanosatellite and Starlink satellite are number one. They are worthy of their name."
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 to welcome these satellites as they rise into the sky.
"Damn it, Cao Cao, my wife, come out quickly and see the gods!"
"Oh my god, this is so magical."
"Replace the trunks of these battery cars with flying swords. This is a perfect Mahayana-level swordsman."
"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 is really like the trunk of a battery car, or a non-mainstream trunk with glitter film on it."
"No, what are you talking about about the trunk? Didn't you notice the characteristics of this satellite?
It has the ability to launch into orbit independently!
Launch independently into orbit!
This means that as many satellites as we build, we can send as many satellites into orbit.
This is to subvert the entire aerospace industry and subvert the entire aerospace history! "
"too strong!"
"I just took a look. In about 9 minutes, a smart robot will come out carrying a newly manufactured satellite.
As we all know, satellites are controlled by the system to fly into orbit, and the computer system does not need to rest.
This is 60 minutes per hour, 24 hours a day.
160 satellites are launched into orbit in one day.
Starlink satellites are all in low-Earth orbit below 1,000 kilometers.
Satellites at this altitude have a short lifespan.
Apart from one company, few countries are grabbing these tracks.
But now, at the anchor's speed.
In less than a year, the entire low-Earth orbit will be filled. "
"I'll go. Doesn't this mean that if other companies want to launch low-Earth satellites in the future, they need to apply for a position from the anchor first?"
"You'd better make it clear which company (dog head) this certain company refers to."
I ignored the almost crazy barrages on the live broadcast.
Chen Yi completely noticed the rows of parameters projected onto the retina by the AR glasses.
These are the parameters and orbit calculations involved in the process of launching a satellite into orbit.
According to the plan that Chen Yi calculated from the beginning.
The entire process of launching into orbit is roughly divided into three steps.
Lift off, pick up speed, and enter orbit.
First lift off from the ground and cross the Karman Line.
According to thrust and mass calculations, these satellites do not turn on the afterburner mode, and the acceleration at low altitude is very low.
The acceleration is only about 0.1 meters squared per second.
That is, it accelerates by 10 centimeters in 1 second.
The only great thing is that it lasts.
Fully charge before taking off.
Charging as you fly, this will keep you accelerating for hours.
But because of the aerodynamic layout design.
Before breaking through the Karman line, the speed of 105 meters per second is the limit.
This means it will reach top speed in about 10 minutes.
According to calculations, the maximum speed is reached at an altitude of 54,000 meters.
After crossing 50,000 meters, we have entered the critical space, and the atmospheric resistance is already very small.
According to Chen Yi’s planning process,
At this time, the satellite will turn on the afterburner mode to improve the jet quality of the ion thruster.
With the help of this altitude, the atmosphere can also replenish propellant, increasing the speed of the satellite to 1,000 meters per second before crossing the Kármán line at an altitude of 100,000 meters.
Then, propellant replenishment is lost.
The satellite closes the air intake, reduces the injection mass and increases the injection speed.
From obtaining greater thrust to obtaining greater specific impulse.
Finally, the propellant carried is used to push the satellite to an altitude of 700 kilometers, and at the same time, it accelerates to the first cosmic speed and orbits.
But now, based on actual liftoff data.
Chen Yi recalculated the plan based on seasonal weather and got a more optimized plan.
"Now that it's summer, the solar radiation is more intense, and the solar charging shell 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, 1,200 meters per second before reaching the Karman Line."
Be sure of your own calculations.
Chen Yi thought.
The acceleration keeps adding up.
Satellites are getting faster and faster.
There was a sudden pause, and then the speed suddenly increased.
Pass through the clouds and enter the stratosphere where solar radiation is stronger
"Damn it, this is Shenzhen 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 just penetrated the clouds.
The tracking team at Shenzhen University immediately started shouting and commenting in the live broadcast room.
They tracked it.
"This is CUHK, and we also took pictures! The satellite flight is normal, 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 it, I see it, a large field of shining satellites, Xiamen University's signal is normal!"
"Zhejiang University has completed the check-in, the attitude of the satellite is stable, and the lift-off flight is stable!"
“Jinling Airlines took the photo”
Because of the advance acceleration, the satellite reached an altitude of tens of thousands of meters in just a few minutes.
One by one, the tracking teams of universities, which were not obscured by the curve of the ground and had been prepared for a long time, took pictures of the satellites and posted excited comments and comments.
Compared with previous lunar landing drones.
This time the satellite was shining brightly, and the difficulty of tracking and photographing was plummeting.
"Teacher, this ion thruster is in the atmosphere and uses an accelerating electric field to replace the combustion chamber of the engine, which can achieve the launch of satellites 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 and ramming. What does scramjet do?"
Shao Kaiwang looked at the satellites that were taking off faster and faster. He had some doubts in his heart and looked at the professor who came to watch the live broadcast.
"This problem cannot be explained in a few words."
The professor looked at his proud student, and for fear of damaging his self-confidence, he organized his words: "The electric field acceleration of the ion thruster is inherently more efficient than chemical combustion.
If the jet quality and jet speed of the ion thruster can be accurately controlled.
At the same time, it solves the problem of high-density electric energy and the problem of external screening and replenishment of propellant.
There is also the issue of ultra-lightweight fuselage.
While being ultra-lightweight, it can also ensure the high temperature resistance, yield strength, and tensile strength of the fuselage.
Solved all these problems.
So the turbojet, ramjet, scramjet, etc. we are currently studying can all be consigned to the garbage heap of history.
If there is a problem that cannot be solved.
This ion thruster is far inferior to combustion engines in the atmosphere and is not suitable for use in the atmosphere. "
"Then these flying ion thrusters, these self-launching satellites"
Shao Kaiwang subconsciously turned around and looked at a group of satellites in the live broadcast room that had exceeded the critical altitude of 50,000 meters.
“Kaiwang, remember one thing, that’s a pervert.
We mortals can't compare."
