Hand rubbing nuclear fusion live in the wilderness

Chapter 329 Restarting the Manned Moon Landing Program
Lithium-sulfur batteries and solar panels will provide enough energy for the new space shuttle, but it's not enough.

The amount of working fluid consumed by the electromagnetic propulsion system is also not a small amount. Although it is much less than the electrostatic electric propulsion engine, in order to break through the gravity of the earth, the speed of the space shuttle must be increased to the first cosmic speed.

The working medium consumed during the speed-up can account for more than half of the total working medium consumption.

If only the electromagnetic propulsion system is used, the working medium that the new space shuttle can carry cannot be taken off from the ground and sent into space.

That's why South Korea combined two electric propulsion engines to achieve its purpose.

When the electromagnetic propulsion system is activated, it is at an altitude of more than 160 kilometers, and it only needs to send the aircraft to a low-earth orbit of [-] kilometers.

And it only takes 10 minutes to increase the speed of the space shuttle to the first cosmic speed. Before that, it only needs to be sent to the starting point of speed-up at a relatively balanced speed.

After waiting for the initial release from the gravitational bondage of the earth, the energy and working fluid consumed will be very low.

This time the satellite launch mission does not require him to go up in person, he only needs to send the satellite up.

And in this way, there is enough space on the spacecraft to store working fluid.

Won has calculated that with the space of the new spacecraft, the vacated space is used to store working fluid, and the amount is enough for the spacecraft to send satellites into low-earth orbit.

In fact, the design of this new type of space shuttle is a coincidence.

He utilizes and combines two different kinds of knowledge information, one of which is intermediate.

In terms of difficulty, it is much, much simpler.

But this does not affect the final review of the planetary communication branch chain mission, because this is the knowledge information he has obtained through hard work, and as long as he learns it, it is within the range that the system can use by default.

And there is no limit to the range of technologies that can be used for side-chain missions.

So this has created two different electric propulsion engines on an aircraft.

One is responsible for sending it to an altitude of eighty kilometers, and the other is responsible for sending it into low-earth orbit.

In addition, this planetary communication branch chain mission is different from the last three-level mission to get extra rewards, and does not require him to enter space in person.

Just use a rocket or a space shuttle to send it to the sky.

In this way, the design of safety and other aspects does not need to be as rigorous as that of the Le Luo triangular aircraft.

It's just that this aircraft needs to be reused.

The goal of the Korean won is not just to send a satellite up.

The rewards of the planetary communication branch chain missions are the same as those of the industrial upgrade missions. The higher the degree of completion, the more rewards you will get.

If it is not for reuse, it is much easier for him to get a launch vehicle to transport satellites.

The repeatability of the launch vehicle is much higher than that of the space shuttle, and the technical content is much simpler. There are also high-purity chemical fuels, which can be exchanged for technology points.

It's just that Won wants to maximize the rewards of the planetary communication branch chain mission.

There is a reason why he set this task to the first place in the second year.

Although the launch of the unmanned space shuttle is still inseparable from manual control, he still has to complete the branch chain task of resource collection during this year.

But it doesn't mean that there are no other ways to launch these satellites without anyone.

During the last three-level mission, he had obtained an additional base from Mount Tai.

There is also a highly intelligent machine housekeeper Xiaoqi plus a highly developed central computer.

Combining these two, you only need to write the corresponding programs and steps, and you can let Xiao Liu replace him to launch the satellite.

Of course, this new type of space shuttle combined with technology is not without its shortcomings.

The first is the shell.

The energy supply of this new type of space shuttle still uses electric energy, and the source of electric energy is gallium lanthanide silicon solar thin film power generation panels.

The solar panel itself is not very fragile, and the Korean Won is also covered with a layer of high-transparency high-strength glass for protection.

If it is an ordinary flight in the space of the planet, this kind of high-strength tempered glass is enough.

But the next thing it has to do is to break through the gravity of the earth and send the satellite into low-Earth orbit.

Breaking through the gravity of the earth requires the flight speed to reach the first cosmic speed, which is 7.9km/s.

At this flight speed, when flying in the atmosphere, it will rub against the air and generate a high temperature of thousands of degrees.

This kind of high temperature will generate huge pressure on the high-strength tempered glass, and it will be easily damaged if it is kept at this temperature for a long time.

If the tempered glass is damaged and the internal power generation board is directly exposed, it will be damaged within 30 seconds.

LaGaSi solar thin film power generation panels can withstand a certain high temperature, but not more than [-] degrees.

If it exceeds seven hundred degrees, the special crystal lattice at the base of the power generation board will melt, and after melting, it will naturally be unable to capture light particles for conversion and power generation.

Therefore, Won needs to stabilize the tempered glass while reducing the temperature generated when breaking through the first cosmic speed, so that the solar power panels can operate normally.

Lithium-sulfur batteries alone cannot support the power reserve for too long.

Fortunately, when the electromagnetic propulsion system really needs to be activated, it is already at an altitude of [-] kilometers, which belongs to the top of the middle layer.

Further up, there is a warm layer with a rather thin atmosphere.

The lower the air density, the lower the resistance and friction generated during high-speed flight, and the lower the resulting temperature.

This has relieved a lot of burden and pressure for the Korean won.

Otherwise, with the atmospheric density of the stratosphere and the middle layer, no matter how strengthened the glass material is, no matter how high temperature resistance it can withstand.

The high-strength, high-transmittance and high-temperature-resistant tempered glass applied to the Lero delta aircraft is already the best glass material in the hands of Won.

This kind of glass can last nearly 1000 minutes at a high temperature of 10 to [-] degrees, but it still cannot withstand the high temperature generated during the first space flight speed.

Although it is not ruled out that he may obtain extremely temperature-resistant glass materials in the future, at least with the material technology he currently has, there is no such thing.

It is a pity for Won that the 'primary magnetic field anti-gravity technology' obtained when completing the third-level task before is not useful.

Otherwise, using this technique, you don't need to think about these things at all.

After completing the third-level mission, he excitedly looked through this technology immediately, but the result disappointed him a bit.

It's not that it can't be made, and it's not a big problem to make it at his current upgraded industrial level.

The problem is that this technology consumes too much energy.

Lithium-sulfur batteries and gallium-lanthanum-silicon solar thin-film power generation panels simply cannot meet the energy requirements for the operation of magnetic field antigravity technology.

The energy consumption of this technology can only be supplied by a nuclear fission power generation device or a nuclear fusion power generation device.

If it needs to run for a long time, only the nuclear fusion power plant can supply the energy.

So at present, this kind of super technology can only be left in the mind to eat ashes.

When will the nuclear fusion power generation device come out, and it must be a small nuclear fusion power generation device, when will this technology really come out.

After all, large-scale and fusion reaction power stations cannot be installed on the spacecraft.

Although there are a lot of things to modify to create a new space shuttle by modifying the Leluo delta vehicle, it is still much easier to build a space vehicle using the technology in the primary aerospace technology knowledge information than starting from scratch.

But after all, the previous foundation is there, and many things can be reused.

The drawings were spread out, and Won showed them, and then briefly explained the technology used on the spacecraft.

After hearing that this is another electric propulsion system that is weaker than the electric propulsion-free fluid engine, the audience in the live broadcast room were a little disappointed.

Of course, it's not their fault.

After several years of live broadcast, the appetite of the audience in the live broadcast room has long been cultivated.

Although most people know that even this kind of weak electric propulsion system is still a black technology in human society, they are still a little disappointed.

Because the previous electric propulsion engine is really amazing.

In addition, in every live broadcast, Won will bring out exceptionally good black technology, which has never been repeated, causing the audience in the live broadcast room to think that the electric propulsion system is not suitable for this time.

Won was also a little speechless about the barrage on the virtual screen that looked down on this electric propulsion system.

If this electromagnetic propulsion system is put into human society, even if the whole country studies it, it will take at least ten years or more on the basis of direction, okay?
The electric propulsion systems currently developed by various countries only have a little more thrust, and the two are simply incomparable.

Of course, the perspectives of experts from different countries are still different.

It is impossible for these scientists who have mastered the top knowledge of mankind to be so short-sighted.

They can think of some things that Han Yuan can think of, so they will naturally look forward to how it will be resolved in the future.

Especially high temperature resistant materials.

The high-temperature-resistant material applied to this space shuttle is not the heat-insulating tile ceramic developed by the United States.

Because of the use of solar panels to supplement energy, this high-temperature-resistant material applied to the space shuttle must be highly transparent.

Otherwise, the solar panels at the bottom cannot receive enough sunlight and naturally cannot provide sufficient energy.

This is a great difficulty.

In addition, various problems such as thermal insulation materials and aerospace working fluids need to be solved.

These issues are of great concern to all countries.

Especially China and the United States.

Needless to say Hua Guo.

The reason why the United States pays special attention to this new type of aerospace vehicle is because of the space shuttle they originally developed by themselves.

Although these space shuttles such as 'Columbia', 'Discovery' and 'Atlantis' are currently in a state of storage, it does not mean that they cannot be activated.

Many of the technologies that the anchor will live broadcast next can be applied to space shuttles to help them improve these space shuttles.

For aerospace, this is what they are most confident about.

They are confident that their aerospace technology can lead all other countries in the world by more than 20 years.

Now is the time for a new round of national destiny disputes. It is not that the top leaders of the United States have not thought about restarting plans to land on the moon and Mars.

It's also what they do best.

At the end of the [-]th century, they used this skill to forcibly disintegrate another country that could compete with them for hegemony.

Even Lao Maozi, who inherited most of the inheritance, still hasn't regained his vitality.

It is not impossible to repeat such a plan again.

But whether it is worthwhile and whether it can be done is a question that needs to be discussed and decided.

After all, the country on the other side is far stronger than the one they dragged down before.
