Hand rubbing nuclear fusion live in the wilderness

Chapter 335 Second Material Development

The thrust is close to [-] kN, although it is not as good as the previous electric propulsion-free medium engine.

But in the eyes of experts from various countries, it is already quite excellent, and it is also a black technology level thing.

After all, whether it is the Hall electric propulsion system independently developed by Huaguo, or the ion electric propulsion system of the United States, it is far inferior to this.

The thrust of this electromagnetic propulsion system can even compete with turbojet engines.

The maximum thrust of the RD-33MK aeroengine developed by the old Maozi Kerimov manufacturer is only 88KN.

And this kind of engine is used in the famous MiG-29K, MiG-35, JF-17 Xiaolong and other fighters.

It can be seen that the thrust of this value is not low.

But what makes experts from all over the world sigh is that the consumption of 'working fluid' by this electromagnetic propulsion system is really terrible.

Under the condition of full power operation, it can consume two hundred kilograms of liquid xenon working fluid per minute.

Although it can provide thrust no less than that of a turbojet engine, it is hardly of much use to humans.

Two hundred kilograms of liquid xenon is consumed in one minute, unless countries can obtain xenon or synthesize xenon on a large scale and at low cost.

Otherwise, no country will use this engine.

Even if it is used on satellites or aerospace engines, it will not be used, and it is really unaffordable.

Although the heavy fuel oil consumed by turbojet engines is also expensive, it looks very cheap in comparison.

Of course, the perverted black-tech electric propulsion engine that can consume extremely low energy and provide extremely large thrust is an exception.

There is no doubt that it is the most perverted black technology that this anchor has produced in the past few years of live broadcast.

In the control room, Han Yuan is still testing the electromagnetic propulsion system and collecting various data.

But the test time is much shorter than the previous electric propulsion engine, and the first test is over in more than ten minutes.

No way, the amount of working fluid cannot support a long test.

A unit of three tons of liquid xenon is only enough to run at full power for 15 minutes.

This meant that South Korean won't be able to test this electromagnetic propulsion engine continuously for two days and two nights like before.

Even if he could exchange technology points for liquid xenon, he still couldn't afford it.

However, compared with the last electric propulsion engine, the various parts of this electromagnetic propulsion engine have passed the qualification test.

The manufacturing process and testing conditions are much better than last time, and can be compensated to a certain extent.

After the test of more than ten minutes was completed, the test results were saved by the central computer and recalled by Won, who carefully checked and watched.

"The maximum thrust is 89.3KN, the minimum thrust is 79.6KN, and the average thrust is 82.83KN"

"9.9% of the working fluid remains, and the number of cycles of liquid hydrogen is 182."

Various data appear on the screen, referring to the knowledge and information learned before, at a glance, Won can complete the analysis in his mind.

Compared with the data in the knowledge information, the overall data of the electromagnetic propulsion system prepared this time is slightly weaker.

But also in the standard floating range and the like.

As for why this weaker phenomenon occurs, it may be related to the processing technology of parts and data detection methods.

Especially the liquid hydrogen cooling system is the weakest one in the whole link.

Fortunately, the alloy materials used in the preparation of the engine are of excellent grade, even if it is weaker, it can hold up.

Generally speaking, the electromagnetic propulsion system this time is weaker than the standard one, but it is still within the floating range and can be applied to the new space shuttle.

In this case, South Korean won has no idea of ​​overthrowing it and redoing it.

There is no problem if the remote control commands and preset commands can be executed normally.

Anyway, he doesn't need to go up in person, and it's not a big problem if the engine is weaker when no one is in the air.

As long as two of the three electromagnetic propulsion engines do not break down at the same time, they can still send the new space shuttle to low-Earth orbit under full power operation.

The test of the electromagnetic propulsion system was completed, and Han Yuan freed up his time.

The new space shuttle is improved from the original Lero delta aircraft. There are some changes in appearance, but there are still many original parts that can be used.

After the key engine technology is solved, the remaining key technology is the surface protection layer.

Because the new space shuttle still uses solar panels and lithium-sulfur batteries to function.

Then the protective layer on the surface must have high light transmission.

Otherwise, the lanthanum gallium silicon thin film solar power generation panel cannot convert enough electric energy.

Then the problem comes, in the highly transparent state, it must have the ability to resist high temperature, buffer temperature or reduce temperature.

If this is placed in the material research and development institutes of various countries, it will definitely be the task of killing a group of top material experts.

Even for the South Korean won, it is no small challenge.

Before that, he searched for some key information in his mind, and indeed found some transparent materials, but they all had various shortcomings and did not meet the requirements.

Therefore, this time, the high-temperature-resistant high-strength transparent material has to be developed by itself.

In the past few days of designing and assembling the electromagnetic propulsion system, Han Yuan has been designing and developing this new type of material at night.

High temperature resistance, high transparency, with a certain strength and the ability to buffer temperature.

This is the requirement for this cover protection material.

It sounds simple, but it can kill a person.

If it's just a single attribute requirement, he has a lot of materials in his hand that can satisfy it.

But it is difficult to do all these at the same time.

Although the two requirements of high transparency and high temperature resistance are not opposed to each other, it is not an easy task to combine them together.

In addition, this material also requires a certain strength and the ability to buffer or reduce the temperature.

This is harder.

The high-strength, high-transmittance, high-temperature-resistant tempered glass that was previously applied to the Leluo Triangle Aircraft is already the best glass material in his hands.

However, this material still does not meet the requirements.

As for other transparent materials, whether it is glass or organic polyester materials, they do not meet the requirements.

So much so that after a month, South Korean Won did not design a suitable material.

But this month's time is not wasted.

Through continuous theoretical design analysis and experimental processing, until about a week ago, Han Yuan probably found a possible way and completed the preliminary theoretical design.

It is currently impossible for him to use one material to combine all the functions.

So Won divided these function points into two parts.

The first part is the most superficial.

Use a material with high light transmission, high temperature resistance and high strength for protection.

The second layer is the middle layer.

The performance of buffering temperature is placed in this layer, and part of the high temperature is buffered through the middle layer, so that the surface temperature reaches below [-] degrees.

It is still possible to disassemble the function point and treat it as two layers.

The key point is the surface layer.

The three properties of high light transmission, high temperature resistance and high strength of the surface layer are necessary for the surface layer material.

Indispensable.

Won has designed a three-layer structure before, and tried to remove the high-strength performance from the first layer and put it on the second layer for support.

In theory, it can work, but when he used the night time to do a simple experiment, he found a problem.

In the absence of high-strength properties, the high-temperature-resistant material of the first layer showed signs of cracking under high pressure and high temperature.

Although it didn't completely collapse, the cracks on the surface of the material were like emperor cracks at the most serious time, which looked shocking.

One experiment is not enough to destroy Won's confidence, but the situation is still the same after two or three subsequent replacements of different materials.

This directly made him dispel the idea of ​​this three-tier distributed architecture, and returned to the two-tier structure.

In the two-layer structure, the research and development of surface materials is the most difficult to deal with.

The conditions are too harsh.

After a long period of theoretical design, data calculation and practice, Han Yuan gave up glass materials and high-temperature-resistant organic polyester materials, and set his sights on gemstones.

Compared to finding a breakthrough on high temperature resistant glass.

It seems to be easier to find breakthroughs in gems.

The main components of glass are silicon dioxide and other oxides.

Silica determines part of the performance of glass, which is a physical boundary that cannot be broken through for the time being.

Gemstones are different. The main component of sapphire and ruby ​​is crystal alumina, which is not weak in high temperature resistance and strength.

There are also ways to solve the transparency. It is also possible to remove the impurities inside and supplement other material molecules that enhance resistance.

The high-temperature melting point of the pure crystalline alumina structure is 2050°C, the boiling point is 3500°C, and the maximum working temperature can reach 1900°C.

That's why Won has set his sights on gemstones.

According to this condition, the material of the crystal system alumina structure meets the requirements of the surface material of the new space shuttle.

Of course, transparency and high temperature resistance are good, but there are also shortcomings.

Crystalline alumina structural materials are somewhat deficient in toughness and resistance, and are brittle to a certain extent and are easily damaged.

Therefore, pure crystalline alumina material is not enough to take on the important role of surface material.

Of course, in addition to red and sapphire, other gemstones have also brought some inspiration to the won.

Like diamonds.

This elemental crystal composed of carbon elements has good transparency, high temperature resistance, hardness and other properties in the case of high purity.

On the downside, it is too brittle and will shatter when hit hard.

So after thinking about it, Won still gave up this material.

However, its elemental crystal structure can be used in later experiments.

In addition to diamonds, the common emerald also brought him some inspiration.

As jadeite in jadeite, its main chemical composition is nanoaluminosilicate, although under high temperature baking, jadeite is easy to change its physical properties, and its internal molecular volume increases.

However, the dense block structure formed by the numerous fine fibrous mineral crystallites intertwined in the jadeite has brought him a lot of inspiration.

This structure makes jadeite have strong toughness and resistance, and the performance of this piece far exceeds that of diamonds.

Using the inspiration obtained from the structure of jadeite, Han Yuan began to make some structural adjustments to the crystal system alumina.

But soon, the first structural adjustment failed.

In the chemical laboratory, Han Yuan picked up the broken transparent material in the container with gloves, looking for the reasons for the failure and thinking about ways to improve.

Soon, he found the approximate point of occurrence of the problem through the analysis of instruments and equipment combined with his own conjecture.

It should be caused by the dense block structure formed by the interweaving of crystallites in jadeite, although this structure provides the material with a certain degree of toughness and strength.

But it also indirectly weakens part of the high temperature resistance and resistance.

After finding the problem, Won carried out the second detection test non-stop.

"Sure enough, here is the problem."

Staring at the data on the screen, Han Yuan muttered to himself.

Learning from the crystal structure of jadeite is useful, but it also has disadvantages.

It can enhance the toughness and resistance of transparent materials, but it also weakens the high temperature resistance of materials.

Previously, the high temperature resistance of transparent materials was around 1000 degrees, but now it has dropped to about [-] degrees.

The temperature difference of [-] degrees is weakened, so that this material is directly abolished.

The level is pulled down to the top glass level in the hands of the won.

Of course, if this is the case, South Korea will give up the research and development of this material.

But he didn't, even if this material is almost abolished, he didn't give up.

On the contrary, South Korea has seen a glimmer of hope and a glimmer of hope in the research and development of this material.

Because he thought of another material structure.

The scales removed from the ancient Warnabi snake have a finely layered structure.

Later, when Won was studying the scales of Warnaby snakes, he accidentally discovered that the scales had a high ability to resist high temperature and burn.

This aroused his interest at the time, but unfortunately there were not enough conditions at that time to confirm whether it was the material of the scale itself or the detailed laminated structure.

Later, after the second comprehensive upgrade of industrial equipment and the manufacture of electron microscopes, infrared analyzers and other equipment, Won re-analyzed the scales of the Warnaby snake.

The final confirmation is that both the material and the stack structure are at work.

In particular, the detailed layered structure in the scales is far more complicated than Han Yuan imagined before.

In the past, the naked eye could not analyze too many things at all, and it could only be seen under special instruments.

These detailed laminated structures are not only laminated, but also have a special triangular crystal structure between the laminated scales.

It is well known that triangles are the most stable structures of all polygons.

Because a triangle with three equal sides is congruent, after the three sides of a triangle are fixed, its interior angles cannot be changed and are determined.

So it is the most stable, and other polygons do not have similar properties.

And this triangular crystal structure gives the scales extremely strong tensile resistance, toughness, strength, etc.

With such a stable structure on a scale, Han Yuan didn't even know how this snake evolved.

If he can't figure it out, he won't think about it. Now this structure has given him new help.
