Chapter 82 Self-launched integrated attack satellite (first order requested))
"For a qualified satellite, the core and most critical thing is communication and communication, which I am good at."
"Then there is the remote sensing detection system. I have mastered this before when I was studying radar, and I am also good at it."
"Then there is the orbit-changing function of the satellite, which is mainly achieved through ion thrusters. This is also good at it."
"In addition, as a qualified satellite, it is indispensable to be equipped with some self-defense weapons. Considering the space environment, it is most suitable to use micro laser weapons. I am also good at this."
"With all the functions combined, the mass can be controlled at 9 to 10 kilograms, which is at the nanosatellite level."
"The last thing is to find a way to send the satellite up. The rocket method is a bit outdated, and we still have to find a launch site."
"The carrying capacity of the lunar landing drone is not high, and it cannot transport several satellites at a time."
Chen Yi took out a pen and paper and wrote down the skills needed to build a qualified satellite.
Finally, I calculated the requirements for the computing satellite to enter orbit, and I probably had a plan in mind.
"Perhaps, I can use ion propulsion and combine it with a solar charging shell to make an integrated satellite and let it float up on its own."
"No problem, low-speed space flight."
"Low-speed spaceflight can first enter orbit and then accelerate. In this way, there is no influence of atmospheric resistance, and the ion thruster can easily accelerate to orbiting speed!"
Starlink system, as a satellite network in space.
The most important thing is definitely the satellite, and the second is the launch vehicle that sends the satellite to the sky.
However, this time, Chen Yi does not plan to build a launch vehicle, nor will he use a moon landing drone.
He plans to combine ion thrusters with satellites to create a special satellite that can enter orbit using low-speed spaceflight.
It is common sense that satellites must enter space.
It must reach the first cosmic speed of 7.9km/s.
If you want to leave the planet, you must reach the second cosmic speed of 11.2km/s.
But in fact, if anyone learns how to climb a ladder and step on each other's left and right feet, they can fly.
Depending on the speed of walking, it can also go out of space and leave the planet.
An aircraft has a lift-off speed of 0.01m/s.
If you continue to fly long enough, you can also fly away from the planet and into space.
This way of leaving the planet and entering space is called low-speed spaceflight.
That is to say, it is possible to spaceflight into space orbit without reaching the first cosmic speed.
However, this method of spaceflight entering orbit consumes more energy and fuel, and generally no one will adopt it.
But for Chen Yi, who uses ion thrusters + solar charging shells to directly create an integrated satellite.
Energy is the least of my worries.
The low-speed spaceflight into orbit method is more suitable.
"However, if low-speed spaceflight wants to enter orbit, there is another point that needs to be paid attention to."
Chen Yi reviewed the plan for low-speed spaceflight.
Soon, I found a point that I almost missed.
That's the propellant.
All combustion power generation is inseparable from boiling water.
All aerospace is inseparable from throwing stones.
The source of power for spaceflight into space is essentially based on Cow's Second Law.
By injecting propellant outward, a reverse thrust is obtained to send the spacecraft into space.
The propellant injected is the stone thrown.
Energy is the energy that throws the stone away.
It's just that normal rocket spaceflight uses combustion propulsion, and propellant and energy are mixed together.
The fuel energy carried by the rocket is sufficient, and the propellant must also be sufficient.
But ion thrusters are different.
The propellant and energy source of the ion thruster are separate.
The energy is the electric energy of the battery, which is charged by the solar panel.
The propellant is the gas accelerated by the electric field.
Nowadays, there is a solar charging case, so energy is worry-free.
But you need to consider whether this propellant is enough.
Without enough propellant, no matter how much energy you get from charging, it will only be useless.
"When satellites are in the atmosphere, they can replenish propellant by adsorbing external gas molecules."
Before the 120-kilometer Karman Line, there is no need to worry about propellant issues.
Even the Kármán line is far from the boundary of the atmosphere, and satellites can still obtain some trace amounts of propellant at this altitude.
In this way, as long as it carries enough propellant to enter orbit before crossing the Karman line, there will be no problem."
Chen Yi spread out the paper and pen and began to calculate seriously.
Generally, satellite orbit heights are divided into three levels.
One is at an altitude of 150 to 200 kilometers, the second is at an altitude of 350 to 1,500 kilometers, and the third is a synchronous orbit of more than 30,000 kilometers.
The lower the orbit, the greater the influence of the atmosphere.
The faster it crashes, the shorter its lifespan.
The altitude of SpaceX’s Starlink satellites is generally 550 kilometers.
This means that the normal lifespan of Starlink satellites will not exceed one year. If some means of increasing the orbital lifting speed are included, it can generally last for 2 to 3 years.
"The propellant is okay, but it needs a supercapacitor."
"Use capacitors to increase power by 89.2 times and increase propellant injection speed"
Chen Yi calculated for a while.
The final result was obtained.
Working fluid engine.
Under the premise that the quality of the propellant remains unchanged.
There is no doubt that the faster the propellant is injected, the greater the thrust obtained.
Previous ion propulsion drone.
Because there is not enough energy, the power needs to be limited.
For the same power, the thrust obtained by increasing the injection mass is greater than the thrust obtained by increasing the injection speed.
But now, satellites do not need to limit power, and at the same time, they must save propellant as much as possible.
This naturally requires a solution to increase power and injection speed.
"Start making trouble!"
"Oh no, start making stars!"
Make sure there is no problem with the plan calculation.
Chen Yi felt energetic and did not rest.
Put on a virtual helmet.
On the premise of ensuring maximum space and structural stability.
Chen Yi added considerations for aerodynamic layout.
We began to design the ion thruster and satellite integrated into one, referred to as the structural diagram of the integrated satellite.
An hour later.
The structural diagram of the satellite is completed.
Chen Yi made another supporting technical plan for the satellite remote control system.
Then, all together, the various equipment introduced into the production area begins automated manufacturing.
Make sure there are no problems with the manufacturing process.
Chen Yi took out another blank main control board, took communication modules, antennas, general-purpose chips, and some supercapacitors used in laser weapons and other spare parts, and began to make the main control board of the satellite.
Forty minutes, the main control board was completed.
Chen Yi then produced a small laser gun and a solar panel with a conversion rate of 54.8% and a II-V compound, which were made into the shape of a satellite shell.
Put the satellite spare parts, remote sensing detection module, main control board, and communication module.
As well as Chen Yi's own personal use, the carbon-silicon lithium battery with an energy density of 5980Wh/KG, including the solar charging shell, is all assembled together.
A frame made of carbon fiber composite material and covered with a layer of solar panels.
The satellite, which has an overall elliptical shape and is larger than the trunk of a battery car, is officially released.
[Item: Self-lifting integrated attack satellite]
[Attributes: Energy x49.1, propellant x8.7, speed x2.1, specific impulse x21.3, strength x16.8, stability x21.4, communication x29.2, remote sensing x21.9, attack x3.6
, main control x0, beauty x8.7]
[Note: This is a nanosatellite with great imagination, uniqueness, powerful performance, and self-lifting capability.
If you write a suitable main control program for it.
Maybe, you can release it into space like a Kongming Lantern]
"It seems that the craftsmanship has not fallen behind, and the attributes are all good."
"None of them have deteriorated due to manual design problems."
"It's like flying into space like a sky lantern. This description is quite appropriate."
Chen Yi looked at the evaluation of this integrated satellite and nodded with satisfaction.
As for the main control program
This is also his first time working as a star, so he really doesn’t understand this.
Maybe I can compile it in two days of research.
But this is such a waste of time.
"System, adjust!"
Colorful lights bloomed, covering the satellite in front of them.
【Energy:49.1→19.3】
[Master control:0→29]
【Speed:2.1→2.9】
[Detected that multiple attributes exceeded the initial value, would you like to read the information? Yes/No!]
"It seems that the basic design of this satellite, the speed of 2.9 points, and the main control attribute of 29 points are the limits."
It seems that it is stuck at 29 points, the main control attribute cannot be improved, and the speed cannot be improved at 2.9.
Chen Yi knew in his heart that this was reaching its limit.
After all, satellites only have this function.
Even if the main control program is out of control, it won't turn into a star battleship.
Moreover, the round shape of the satellite makes it difficult to fly fast.
"Read."
Chen Yi chose to read.
One after another information emerged in my mind.
Nothing special.
This is a control system for satellites and ion propulsion.
With the help of the system, it will be digested in just a few minutes.
"The other attributes will be adjusted together."
Complete digestion of satellite master control information.
Chen Yi continued to adjust other attributes.
Speed ​​attribute has been limited to 2.9, want to read technical information.
Other attributes can be adjusted to within 29 at most, and cannot exceed 10 times the lowest attribute.
call!
The light bloomed and enveloped the satellite.
In this adjustment, Chen Yi planned to sacrifice the two attributes of communication modules that he could manufacture and produce, as well as energy batteries, to fulfill other attributes.
Ten minutes passed and the light dissipated.
What appeared in front of Chen Yi was a satellite as bright and sparkling as a sapphire.
[Item: Satellite—as bright as a gem!]
[Attributes: Energy x3, propellant x8.9, speed x2.9, specific impulse x28.3, strength x28.8, stability x28.4, communication x3, remote sensing x28.9, main control x29, attack x3.9
, beautiful x27.7】
[Detected that multiple attributes exceeded the initial value, would you like to read the information? Yes/No!]
[Note: This is a collection-grade, gem-like exquisite satellite. Its low energy properties and communication make it impossible to fly into space again.
Perhaps, you can store it at home and use it as a shining home guard router. This is also a good choice]
“Is this how beautiful attributes shine?”
At this moment, Chen Yi felt like his eyes were going to be dazzled.
He quickly lowered the aesthetic attribute by 15 points, from 27.7 to 12.7.
Now, the dragon will go crazy when it sees the satellite.
It has become a satellite that shines much brighter than Dongfanghong-1, but is still within the acceptable range.
"The attack of 33.9 is the limit. This laser gun is still too small."
"Propellant properties, 8.9 is also the limit."
"It seems that this integrated satellite can go up to a mid-level orbit of about 1,000 kilometers at most and cannot enter a synchronous satellite orbit."
Look at this beautiful satellite.
Chen Yi took a deep breath.
Select Read Properties.
Boom! A lot of information flooded into my mind.
A few hours later.
Chen Yi digested all the information.
I have a completely mature and perfect plan for Starlink satellites.
Think about it.
Take out your phone.
"Since we are going to build Star Chain, we might as well do it more generously and openly, and earn a lot of consciousness waves to feed Xuannv."
"Anyway, with the laser defense array, there is no need to worry about any danger."
With that said, Chen Yi logged into his self-media account that he hadn't logged in for a long time.
Uni-President released a countdown live broadcast notice.
[E114,05,51.69,N22,38,18.74 Countdown to 12 hours, Starlink takes off, look forward to it! 】
Chapter completed!
