Hand rubbing nuclear fusion live in the wilderness

Chapter 342 Return of Space Shuttle Zero

The next day, the sky was bright, and Han Yuan had already woken up.

Space Shuttle Zero will not return until [-]:[-] noon, and the landing time is calculated to be around [-]:[-] pm.

After getting up, Han Yuan made breakfast first, and then went to the control room to check the data information and the photos sent back by the space shuttle to see if there was any abnormality.

"Current altitude: 162.73km."

"Current working fluid remaining: 23.76%."

"Current power reserve: 98.72%."

"Current solar panel temperature: 279.2°C."

"The current highest surface temperature of the spacecraft: 279.2°C."

"Current command execution number: 172; remaining unexecuted number: 104, cumulative command execution error number: 7 (already counted)."

"."

In the control room, Han Yuan carefully observed each piece of data, which could feed back the status of the zero space shuttle.

In particular, the data generated by the execution of the seven commands is particularly carefully viewed, not only calling out the wrong command, but also viewing the corresponding logs together.

"Preparation order 63 executed."

"Error, the detection height has not reached the specified index, and the execution of Order No. 63 is suspended."

"The data detection is complete, the altitude has reached the specified index, and the preparatory order 63-1-8 is executed."

"Preparation order 79 executed."

"Error, it is detected that the power index is lower than 90%, and execution is suspended."

"The data detection is completed, the power supply reaches more than 95% of the specified index, and the preparation order 79-9-1 is executed"

"Preparation order 84 executed."

"Error, the detection height has not reached the specified index, and the execution is suspended."

"The data detection is complete, the altitude has reached the specified index, and the preparatory order 84-3-4 is executed"

The seven erroneous instructions are all of this type of data.

Some are caused by the height, some are caused by the power reserve of the lithium-sulfur battery.

Because when preparing to execute the command, the function chip on the zero space shuttle will call to compare the current data and the pre-set data, and when the data is found to be different, the execution is suspended.

This kind of erroneous command execution did not have much impact on the entire process, and it slightly delayed the lift-off process at a certain stage.

In the next stage, the preset multiple commands will be selected and the closest one will be executed.

For example, "Preparation Order 63", the reason why it failed to execute was that the altitude of Space Shuttle Zero failed to reach the preset value for the execution of the order.

Judging from the log file, when the preparatory order 63 was executed, the altitude was still 3.7 kilometers away.

For rockets or space shuttles, this is only a one-second flight distance, but a one-second gap may cause the satellite to fail to enter orbit normally, so adjustments must be made.

The adjustment method is very simple, that is, through automatic comparison and analysis, select the most suitable preparatory command to start and make up for it.

These subsequent preparatory orders were all preset by Won. He had long considered some unexpected situations that might occur during the flight of the space shuttle.

Including failure to reach the specified altitude at the specified time, insufficient electrical energy storage capacity of lithium-sulfur batteries, excessive surface/internal temperature of the space shuttle, etc.

The launch of Space Shuttle Zero is staged. After climbing a distance of more than ten kilometers, the rangefinder will send signal waves to the ground three times in a row to accurately judge the height from the ground.

After the altitude is judged, the value will be compared with the pre-set value. If there is a difference of 0.5 kilometers, the functional chip will discard the pre-command and search for a matching one from the backup command to start.

Then pull the height to the preset value in the next stage.

While judging the altitude, it will judge the amount of electric energy stored, the temperature inside the space shuttle, and other values.

Through continuous staged comparisons and corrections, the zero space shuttle can enter orbit according to the predetermined goal.

Sounds simple, but it's actually not that hard to do.

But technology is the key.

If there is no ultra-low energy consumption electric propulsion-no working medium engine, no high-efficiency photoelectric conversion gallium lanthanide silicon solar power generation panel, and no high-energy storage lithium-sulfur battery, it is impossible to achieve this level.

In human society, if there is no additional technological interference, I am afraid it will take at least 100 years to achieve this step.

Not even 100 years.

Whether this level of spaceflight can be realized depends on whether controllable nuclear fusion technology can be developed within the next 100 years.

Moreover, it is not enough to develop it, and it needs to be miniaturized, the kind that can be installed on the space shuttle.

Otherwise, it is almost impossible to achieve this level by relying on fossil fuels such as hydrogen-oxygen fuel or methane used in various countries today.

The efficiency of fossil fuels is too low. If propulsion is carried out in this way, the amount of fossil fuels carried by the spacecraft is an astronomical figure.

And the weight of fossil fuel itself is very large, carrying too much, the space shuttle cannot fly.

After checking the seven erroneous instructions one by one, Han Yuan checked the running track of 'Number Zero' and checked other data after confirming that there was no problem.

Including some photos taken by 'Zero' during the flight, Won checked them all, and left the control room after confirming that there was no problem with each item of data.

There are still more than seven hours and close to eight hours before the return and landing of space shuttle zero.

Seven or eight hours is not short, and he can't waste it. It is the best thing to finish the unfinished satellites yesterday.

He had manufactured one-third of the parts for the communication satellite last night.

The rest of the parts and assembly don't take too long.

This is the advantage of a strong physique. With his written value far exceeding that of ordinary people, he can easily carry things that he could not move before.

Coupled with the ability to multitask, and the cooperation of tools such as hanging rails and pulleys and some bonobos, he can quickly complete the assembly of various instruments and equipment.

The previous Le Luo delta vehicle and the zero space shuttle can be assembled, not to mention the satellites that are infinitely smaller in size and simpler in structure.

The satellite he designed, except for the larger antenna group used to send and receive signals, the other things are not big, and the materials used are all lighter metals.

Such as titanium alloy, aluminum alloy and the like.

The total weight did not exceed [-] kilograms even including working medium, so he could easily lift it up by himself.

The busy time passed quickly.

In the afternoon, Han Yuan was transporting the parts made by the CNC machine tool to the assembly room, and the pager he carried in his hand beeped 'Didi Didi'.

Han Yuan glanced at the pager, which showed the time 'three o'clock in the afternoon', and immediately understood that the zero spaceship landed in half an hour.

This is his pre-set program. In addition to calling when encountering problems, he will also be called once when the space shuttle returns.

After speeding up the delivery of the satellite parts to the assembly room, Won quickly rushed to the test site.

In the clear blue sky, a small black spot has already appeared in the eyes of the Korean won and the audience in the live broadcast room.

Everyone understood that it was the number zero that was landing on the return flight.

【Come back, come back! 】

[He actually came back? 】

[Fuck, when was it so easy to launch a space shuttle?Just push a button? 】

[It’s not easy to send it up, but it’s still possible to come back, and it’s fine to come back, but there’s no one to control the whole process?What kind of black technology is this! ! ! 】

【Simple?Have all the work that the anchor did before been eaten by you?What's more, people's technology is already high. 】

[The anchor said that this thing went to space, do you believe it?Going into space is not that easy. Going into space without any intelligence on the ground is just like nonsense. Maybe you just go to the sky and come back. 】

[If this thing can return successfully, can it be used for manned spaceflight? 】

[Maybe within a few decades, traveling to space and the moon will be as simple as eating and drinking. 】

[I remember that the failure rate of space shuttle launches seems to be very high? 】

[No, the space shuttle of the United States has carried out 135 launch missions, 133 of which were successful. This success rate is already quite high for a spacecraft. 】

[The success rate is quite high, but once something goes wrong, the group will be wiped out, which is quite miserable. 】

[It’s no wonder that nothing happened. Before the launch of the Challenger, the technical department repeatedly emphasized that the sealing ring is not good at low temperature, and the bundled booster needs to be checked, but the government is willing, insisting on saving face, and life and death. Catch this launch window. 】

[The people in the technical department thought they would BOOM at the first ignition, and then went to the sky. They really celebrated, but they were instantly slapped in the face at 73 seconds, and they set off fireworks directly. They felt sorry for the astronauts above. 】

[At that time in the Cold War, I couldn’t afford to lose, so I had to launch ahead of Big Brother. 】

[The nature of the Challenger explosion is the same as that of the Cherubell Nuclear Power Plant. They are both extreme products of the Cold War period, and the technology was forcibly used when it was not ready. 】

[Damn it, if something like this happens in our country, the sky will be turned upside down?The relevant officials have to be axed. 】

[Didn't it mean that the space shuttle is not worthwhile?That's why we didn't do it. We could have crossed the river by touching the eagle sauce. 】

[Not cost-effective is one aspect, and the other is that the technology is not good enough. 】

In the sky, the figure of Space Shuttle Zero is rapidly growing. The audience in the live broadcast room is a little excited, some are surprised, and some are chatting with other people when they will be able to go to space.

Some viewers don't believe that it is so easy to send the space shuttle into space, thinking that this thing can at most go around in the sky and then come back.

However, most of the viewers still believed in this live broadcast. After all, the live broadcast has been live broadcast for so many years, and this anchor has never fooled anyone.

What was said was done.

As for experts from various countries, there is not much doubt that the zero space shuttle went to space once.

Although the space shuttle made by this anchor looks very simple, and in terms of control, it looks like a play house.

But the various technologies used in it are quite high, and it is not impossible to fly into space.

The thrust problem is solved, even if it is a brick, it can fly into space stably.

Like this anchor, consuming tons of liquid xenon at one time just to send the space shuttle into the sky without any command on the ground is like a hero in the eyes of experts from all over the world.

They can only express envy that they cannot afford this kind of consumption.

However, this also proves that the other party's technology is far superior to that of humans on earth, and liquid xenon, which is extremely valuable in the hands of humans, is just an ordinary material that can be consumed at will in the hands of the other party.

Just like oil and coal, you can burn it casually.

After more than ten minutes, the zero space shuttle with brown-red tail flames spraying from the bottom can clearly see the whole picture.

The landing site was still on the test site, but it was slightly different from the launch point, with a distance of more than ten meters between the two.

This distance is within an acceptable range for the Korean won.

When the space shuttle landed, the strong plume blasted some dust and gravel on the test site all over the sky.

Waiting for the airflow to slow down slightly, Han Yuan fanned the turbid air in front of his eyes, and stepped forward to check the situation of the space shuttle.

The exterior looks unchanged.

The first layer of HY-type aluminum oxide laminated material used for protection was visually inspected first, and some of the protective layers were not even scratched on the surface, but there were some dust.

But this was attached when it just landed.

After inspecting part of the surface materials, Han Yuan nodded slightly.

He is quite satisfied with the performance of the HY-type alumina material.

But having said that, the Mohs hardness of HY-type alumina material is as high as 8.4, which is comparable to gemstones.

You must know that the hardness of corundum, that is, red sapphire, is only 9.0, and some poor-quality ones cannot reach it.

With this hardness, even if you scratch it with a knife, it will not leave any traces.

When flying, as long as you don't hit a bird meteorite or something, there won't be much damage.

Entering the interior of Space Shuttle Zero, Han Yuan first carefully removed the storage device.

Although Zero is an unmanned space shuttle, there is still a manned control room inside.

This point is basically copied from the previous Leluo triangular aircraft, with only some extremely simple functions.

As for his dismantling of the storage device, it was because he could take it back and analyze the aerospace log data.

Although the data inside could be exported wirelessly, the efficiency was too slow for him to bear.

The log is too large, and it is the fastest way to directly remove it and connect it to the central computer for reading and analysis through a wired method.

The magnetic storage device stored in the airtight metal container was disassembled by the Korean won and transported back to the computer room first.

However, it will take another day or two to analyze the data.

He will now do a detailed inspection of the overall hardware of Space Shuttle Zero.

Two different types of engines, lithium-sulfur battery systems, functional chips, the metal skeleton of the space shuttle, solar panels, and more.

These all need to be tested by instruments.

Including the HY-type alumina material, which has no problem with visual inspection, it also needs to be analyzed by professional instruments.

The inspection for the space shuttle is the first thing that needs to be done after the space shuttle lands.

Just like after the plane lands, the maintenance personnel on the ground will conduct the maintenance inspection as soon as possible.

The reason is that some defect issues are time-sensitive.

It may be found when you check when you land, but you won't be able to find it when you check after a day or two.

As for the data reading and analysis of space logs, and the manufacture of satellites, those things can be dragged back without any problem.
