Hand rubbing nuclear fusion live in the wilderness

Chapter 338
After briefly explaining the cosmic speed and the feasibility of sending the space shuttle into space at a slow speed, Won ignored the barrage related to this issue.

Although there are still people on the screen who are constantly arguing, but that is purely due to low IQ and low search quotient.

In fact, these things do not belong to the knowledge of common sense, so he just talked about it a little bit.

Although there are things like the first cosmic velocity and the second cosmic velocity written in the textbooks of high school, it is even required to calculate the cosmic velocity during the exam.

But after all, it is not very detailed.

For the definitions of the first and second cosmic velocities in high school textbooks, if you study related majors in university, you will find that there are many things hidden behind them.

And things like the speed of the universe are things that only appear in the relevant majors or graduate courses designated by universities.

It is normal for the audience not to understand at the beginning.

Chatting with the audience in the live broadcast room, more than ten minutes passed quickly, and [-]:[-] was coming.

The numbers on the screen turned into a countdown, and Won stood in front of the console, took a deep breath, and put his finger on the red round button.

"ten"

"Nine"

"Eight"

"Seven"

"."

The numbers on the display returned to zero little by little, and the Korean Won pressed the red button hard to start the initialization process.

In the distance, after receiving the start signal, the No. [-] space shuttle silently standing on the test site started the internal power supply, started the chip with stored functions, and started the electric propulsion-free fluid engine.

The teeth-stinging low-frequency resonance came again, and the brown-red tail flame appeared at the bottom of the space shuttle.

The output power of the electric propulsion engine continued to increase, and the space shuttle began to lift off the ground, slowly and straightly flying towards the sky.

In the control room, through the shooting device installed on No. [-], the surrounding scenery of the aircraft is transmitted through video.

This is the first time that Won has used a shooting device, and the effect is not bad, and the images transmitted are quite clear.

It is not difficult to convert the captured video into binary code, transmit it to the ground base wirelessly, and then convert it through the central computer.

The difficulty lies in real-time transmission and conversion, as well as the manufacture of real-time shooting equipment.

As for the slight jittering of the screen, it is an unavoidable defect for him now.

In fact, if it wasn't for the fact that nobody sent the satellite into the sky this time, Han Yuan estimated that he might have to wait for a while before making filming equipment.

The main reason is that it is not used in normal times, and wireless reception and video conversion will take up a lot of performance of the central computer. If it is not necessary, it is meaningless to make this thing out.

As for what is used for monitoring, it is unnecessary.

He is the only human being on the entire simulated planet, what is he used to monitor?
Monitor the play of bonobos?

Won felt that he was not bored to this point.

But this time to push the space shuttle to the sky, it is still necessary to install some shooting devices on the spacecraft.

Although it doesn't play a big role, it can at least let him know the current status of the space shuttle or satellite.

In other words, when the space shuttle encounters an accident, it can know exactly what happened when it hit it.

In the control room, on the display screen, the pictures transmitted by the space shuttle did not change much.

After all, straight up into the sky, except for the shooting device at a specific angle, the scene captured by the shooting device in other places will hardly change.

However, in addition to the shooting pictures, there are many other data that can show the current situation of the space shuttle.

Such as the altitude of the space shuttle, surface temperature/internal temperature, energy reserve, command execution and so on.

These things can provide feedback on the status of the space shuttle.

After the Space Shuttle Zero took to the sky, Won did not stay in the control room to observe the situation, but only stayed for half an hour.

For half an hour, he carefully analyzed the various data of the space shuttle.

There is a slight deviation from the simulated data.

For example, the current altitude, according to previous calculations, the space shuttle should be at an altitude of 23.7 kilometers from the ground after half an hour of operation.

But now the data displayed is only 23.3 kilometers.

The difference is 0.4 kilometers.

However, his foolish launch method will definitely have errors.

0.4 kilometers, within the allowable error range.

The space shuttle goes to the sky, both external and internal will have certain influence on it.

The instability of the airflow, the thickness of the clouds, the power of the electric propulsion engine, the data feedback of the distance measuring instrument, and the transmission of wireless signals will all have a certain impact on the final displayed data.

Even countries as powerful as China, the United States, and Big Brother before the disintegration have failed countless times when rockets were launched to send satellites into the sky.

According to statistics, from 1958 to 1965, the two major powers during the Cold War launched a total of more than [-] satellites.

And the number of successfully entered orbit is less than [-].

The probability of success is only about one in ten.

And even if it is a successful launch, it is normal for data errors to occur.

Errors are not terrible, just follow-up control of rockets or satellite adjustments will do.

Every launch of a rocket/satellite is a very complicated and delicate matter in human society.

That requires the concerted efforts of countless people and countless computers.

The main reason is that it is impossible to send the space shuttle into the sky at a lower speed like him.

A high-thrust rocket flies at super high speed, and a slight mistake can be fatal.

Looking at this kind of thing, a rocket cannot control its flight trajectory like a space shuttle.

In most cases, the lift-off trajectory is calculated in advance.

Like the space shuttle Zero, if there is a problem during the lift-off process, the Korean won can forcefully issue instructions on the ground to correct the orbit or make it return.

It's just that doing so is very risky. After all, people are no longer on the space shuttle and cannot control it effectively in real time.

So things like correcting the track, won to the preset program.

For example, Space Shuttle Zero will stay there for a period of time after climbing to a low-Earth orbit of 160 kilometers.

During this time, the space shuttle will orbit the Earth.

The internal small computer will constantly compare various data collected by external instruments, such as altitude, temperature, airtight density, angle and other information, with various preset values.

After the comparison is completed, if there is a deviation, the computer will automatically start the adjustment plan, and pass a series of instructions to the engine to adjust the height, angle, etc.

The most critical thing is the subsequent satellite release, as well as satellite orbit adjustment, angle adjustment, speed adjustment and other things.

If all countries can do the same as him, then launching a space shuttle or an airplane will be as simple as eating and drinking, and even landing a man on the moon will be very simple.

But it is a pity that countries cannot afford to consume it.

At present, for a powerful country that can launch satellites, each launch of a satellite still costs a lot.

A rocket launch is equivalent to throwing real money into the sky.

Although sometimes satellites and space stations are sent to the sky regardless of the cost, they are very rare.

Most of the time, the money used to launch satellites is carefully calculated.

After the Cold War, the reason why the United States did not engage in aerospace engineering was because it was too expensive to consume.

Needless to say, according to the Korean Won, one trip to the sky basically consumes two billion worth of liquid xenon working fluid.

Even the space shuttle developed by the United States requires at least [-] million meters of gold for a single launch.

No country can resist long-term space activities before space technology has made greater progress.

Too much money and resources were spent.

On the contrary, manpower, which is extremely precious to the Korean won, is worthless in front of other countries.

When Huaguo was building nuclear bombs, because there was no computer, the data calculations were done bit by bit by countless people using abacus.

The technology is not enough, and manpower is needed, which is probably the case.

And manpower is an extremely precious thing in the Korean won.

He is the only one in the whole world.

Therefore, we can only try our best to weaken the stage that requires a lot of manpower in the same technology.

Simple fool-like operation is the most suitable.

To send a satellite to the sky, you only need to press the launch button, and then the aircraft will automatically go to the sky, launch the satellite, and return.

For South Korean won, this means that manpower is not enough and technology is needed.

After staying in the control room for about half an hour, after confirming that there was no major problem, Han Yuan left the control room.

The space shuttle has already gone to the sky, and before there is no problem, it is impossible for him to write other control programs to disrupt the execution of normal programs.

Now I can only let Number Zero follow the pre-set procedures and walk bit by bit.

It was useless for him to remain in the control room.

If there is a problem, the wireless signal will be passed to a bb pager-like device in his hand.

See you in a day. If the zero can return normally, then there is no problem, and the satellite can be launched normally.

If number zero doesn't come back after a day, you have to start all over again.

By that time, Won will consider using a more robust rocket to launch the satellite.

However, the extra rewards for the full level are no longer with him.

Although technology points can be used to exchange for rocket parts, it is really not worthwhile to use points to exchange for processed parts.

A unit of liquid xenon only needs more than 6000 technology points, while an electromagnetic propulsion engine needs more than [-] points.

Even with nearly a million points, South Korean won is not willing.

The gap in the consumption of technology points between raw materials and parts that have been processed many times is too great.

Taking liquid xenon and electromagnetic propulsion engine as an example, the difference between the two may not be obvious.

In other words, you will know how big the gap is.

One unit of iron is five tech points.

But to exchange a unit of solid iron pipe, only change the shape, not modify anything else, but you need 25 technology points.

In Won's view, this is nothing more than melting the iron ingots and pouring them back into the mold according to a series of processes and testing the parameters. There is no need for a five-fold price difference.

Yet this is how the system judges.

Sometimes Won even suspects that the creator of this system may be the kind of civilization that is extremely short of manpower?
Otherwise, how could there be such a situation where the raw material is quite cheap, but the artificial product after a few random knocks is expensive?
Leaving the control room, Han Yuan returned to the workshop and found the 'satellite structure map' that had been drawn before from the wooden cabinet.

If you don't consider other functions, something like a satellite is actually a signal transfer station hanging in space.

For the simplest communication satellite, a solar panel for power supply, a rechargeable battery, and a set of signal receiving/transmitting systems are actually enough.

But this kind of satellite hangs in the sky, especially the ultra-low low-earth orbit of 160 kilometers, and it will fall from the sky within a day.

Therefore, on the basis of communication, a power system must be added.

If conditions permit, a small computer must be added to calculate data, maintain the altitude of the satellite, and handle satellite orbit changes and other things.

After that, things that need to be added are generally optional.

For example, long-distance detection imagers, which are mostly used on spy satellites, military satellites, and map satellites.

Another example is the solar wind analyzer, which is carried by ordinary satellites, especially those performing long-distance voyages, to analyze and avoid the interference of the solar wind.

Or ion mass spectrometers and star finders, which are usually carried by satellites or telescopes exploring outer space.

However, these things are optional, and the Korean won has not been added to its own satellite.

The satellite structure drawn on the paper is actually quite simple.

A pair of lanthanum gallium silicon solar thin film power generation panels + lithium sulfur battery + small electromagnetic propulsion system constitutes the energy power supply system.

A functional chip + an altimeter constitutes an orbit keeping system, which is used to judge the altitude of the satellite.

Finally, there is a group of different types of antennas, some are omnidirectional and some are directional, and these antennas are responsible for receiving and transmitting signals.

The three major parts constitute the main structure of the satellite that Won will send to the sky next.

Won plans to send up at least [-] satellites in half a year.

That's thirty shots.

This is the least, if there are more, it is not impossible to get [-] or even [-] satellites.

However, the number of satellite launches depends on the status of Space Shuttle Zero.

After all, every time a satellite is launched into the sky, it will cause certain damage to the space shuttle.

Especially the surface-covered HY-type alumina laminate material, which is a consumable to a certain extent.

However, it is much better than the situation on the American space shuttle that requires a complete replacement of most of the engine except for one launch.

Because the substantial acceleration of the zero space shuttle has already entered the warm layer.

However, the air in the warm layer is quite thin, and the damage to the surface protection material will be countless orders of magnitude lower.

According to Won's calculations, the HY-type aluminum oxide laminate covering the surface of the space shuttle needs to be replaced almost every twelve times.

The main reason for replacement is that friction will affect the light transmittance of the protective material, which in turn will affect the solar power panels arranged underneath.

Insufficient energy supply is a fatal problem for a space shuttle.
