Chapter 337 Excellent Thermal Conductivity of HY Materials

The completion of the HY-type aluminum oxide laminate material gave Won a big sigh of relief.

High transparency, high temperature resistance, and high strength, these three properties are the properties that must be possessed by the surface layer of the new space shuttle.

Fortunately, this newly developed material is perfect enough.

As for the insulation effect, that was an unexpected discovery.

"It's not known how low the material's thermal conductivity is."

Han Yuan looked at the materials being tested with twinkling eyes, and thought of the insulation tiles on the space shuttle developed by the United States in the 90s.

It is indeed an awesome material. After being taken out of the [-]-degree high-temperature furnace, it can be held for three seconds without burning your hands.

This step can be achieved, in fact, thanks to the original Cold War.

The cold war between the Sumi two countries has greatly improved human technology.

Aerospace technology, moon landing, military equipment, etc., many things that still look awesome today were invented at that time.

Even so many years after the end of the Cold War, there are some things that America can no longer make anymore.

For example, the super-large launch vehicle of the Saturn series is one of the prides of the aerospace history of the United States.

But now, the United States simply can't spend so much money and mobilize so many resources to manufacture this kind of thing.

After the end of the Cold War, after the benefits of the disintegration of Big Brother, the United States has not made any outstanding progress in technology, and it can even be said that it is paving the way.

Just like the space shuttle, some technologies are really awesome.

Won did not expect that the laminated material that is currently being tested will have a thermal insulation effect like a 'heat insulation tile', but it can be expected.

This is an extra surprise. At the beginning, he never thought that this material would have a thermal insulation effect, so no matter how high or low, he can accept it.

After all, no matter how small a mosquito is, it is still meat, and a dime is still money. It is better than nothing.

And if this kind of material has a good temperature insulation effect, then the cooling material of the middle layer, Won can no longer need to develop it by itself.

In the knowledge information in the mind, there are many materials that can buffer and reduce the temperature that can be used.

It would be nice to save some time.

Soon, the tests on the thermal conductivity and temperature insulation performance of HY-type alumina laminate materials were completed.

For the sake of data rigor, Won did it three times.

Comparing the results of the three times, the data is very surprising.

"For the first test, the thermal conductivity at 0.2913°C is 0.5612W/(m·K); the thermal conductivity at 0.6741°C is 0.9211W/(m·K); the thermal conductivity at [-]°C is [-]W/(m·K) ;The thermal conductivity is [-]W/(m K) at a temperature of [-] degrees."

"The second test, the thermal conductivity at 0.2922°C is 0.5654W/(m·K); the thermal conductivity at 0.6710°C is 0.9181W/(m·K); the thermal conductivity at [-]°C is [-]W/(m·K) ;The thermal conductivity is [-]W/(m K) at a temperature of [-] degrees."

"The third test, the thermal conductivity at 0.2901°C is 0.5609W/(m·K); the thermal conductivity at 0.6698°C is 0.9232W/(m·K); the thermal conductivity at [-]°C is [-]W/(m·K) ; The thermal conductivity is [-]W/(m K) at a temperature of [-] degrees."

Three data tests show that the thermal conductivity of the HY-type alumina laminate material is as low as 0.29W/(m·K) at 1, and does not exceed the value of [-] at [-].

Although it is still not as good as the insulation tiles on the space shuttle, such a low thermal conductivity made Won's eyes shine and he felt happy.

The thermal conductivity of a 2 cm thick extruded board is about 30W/(m·K) at about 0.71 degrees.

Judging from the data, the thermal conductivity of HY-type alumina laminated materials is much lower than that of most building materials.

If this material is used as glass, the thermal insulation performance of the room will be greatly improved.

Moreover, such a low thermal conductivity means that after using this material as the surface layer, ordinary cooling materials can be used in the middle layer, which saves him a lot of time.

The research and development of cooling materials is much easier than that of surface materials, but if it is necessary to conduct independent research and development, at least it will take more than a week.

Wouldn't it be nice to save a week of time for something else?

After the completion of the thermal conductivity and temperature insulation tests, the remaining two more time-consuming tests won't be guarded anymore.

The key materials have now been completed, and what we need to do as soon as possible is to build a new type of space shuttle.

This space shuttle transformed from the Leluo triangular aircraft has many structures and designs that are the same as the original ones.

These things won't move, and they will be exchanged directly through technology points.

Millions of science and technology points, although not a lot, but still considered a surplus, there is no need to be frugal on this kind of thing.

And this time, the production and assembly of the new space shuttle, with the help of chimpanzees and bonobos, is no longer Won alone running back and forth to adjust tools, hanging rails and other things.

After long-term training and instructions, the IQ of the two groups of chimpanzees is no less than that of a ten-year-old child.

There's absolutely nothing wrong with assisting with things like manipulating rails, pulleys, fixing ropes, etc.

With the assistance of chimpanzees, Won assembled and spliced ​​the new space shuttle much faster than the Lero delta craft.

After completing the production and preparation of all parts and materials, it took him just over a month to complete the overall assembly of the new space shuttle.

But this time point is not short.

After the overall assembly of the space shuttle is completed, nearly four months have passed since the second year of the Starlink mission.

It takes four months to complete a space plane that can send satellites into the sky and can be reused, which is already super efficient in the eyes of all countries.

However, in Won's opinion, it took a bit too much time.

Although it took a lot of time to develop HY-type alumina laminated materials, most of the materials and parts can be exchanged through technology points.

Only about a third is to be remanufactured and produced.

Moreover, the assembly was assisted by chimpanzees, so it still took nearly four months.

After spending so much time, Won was a little dissatisfied, but there was nothing he could do.

This is not the first time he has experienced the shortage of manpower.

I experienced it once when I made the Leluo triangle aircraft in the last three-level mission.

This time he would have spent even more time assembling without the help of the chimpanzees.

Han Yuan knew clearly that he had reached his limit alone.

Although the gene medicine and human body development medicine are powerful, they are still limited after all, and it is impossible to develop the human body's ability without limit.

Unless he is transformed into a superman and able to fly, otherwise, no matter how excellent his ability is, there are limits to what he can do.

"Need to get a functional robot out ASAP."

Shaking his head, Han Yuan sighed slightly and threw out the thoughts in his mind.

"When will this dog system unlock the time limit?"

"In the case of a fixed task and a fixed time, sometimes he needs to shorten his sleep time to complete the task, and there is nothing to do other things at all."

If there is any dissatisfaction with this system, the biggest place is here.

Han Yuan felt that many of the knowledge and information in his mind were very useful and could be broadcast live.

In particular, there are many things in medicine that can benefit mankind.

Han Yuan once found a kind of medical technology when he got the basic information of bionic application knowledge.

Called 'directed target drug'.

This is a kind of medicine produced by imitating 'bacteriophage'.

One of the oldest viruses on earth.

Phages are the most ubiquitous and widespread group of viruses, often found in places that are teeming with bacterial communities.

You can find phages in the soil, in the intestines of animals, and even now you have hundreds of millions of phages on your hands.

Of course, phage is a general term for viruses that infect microorganisms such as bacteria, fungi, algae, actinomycetes, or spirochetes, not a certain type.

If the types of this thing are different according to the bacteria attached, I am afraid it is impossible to calculate how many types there are.

Viruses that can cause lysis of host bacteria are almost always called bacteriophages.

But according to the shape, there are three types: 'tadpole-shaped, micro-spherical and filamentous', and if it is subdivided a bit, there are six types.

The biomimetic target drug is the tadpole-shaped phage.

The phage looks like a man's 'tadpole' with a long, thin tail.

That's what they use to inject genetic material.

The targeted drug that imitates this tadpole-shaped phage kills bacteria in a different way than normal drugs.

After it is injected into the human body, it can search for and recognize special bacteria like a phage, and then attach and inject its own genetic material into the bacteria.

When the reproduction reaches a certain level, the offspring will break through the bacterial wall and kill the bacterium.

And the countless bionic drugs produced by reproduction will actively look for other targets, and with the help of the reproduction mechanism, they can quickly clear away harmful bacteria.

This method is like a chain virus, and the number will skyrocket in a short period of time.

After targeted cleaning of special bacteria, this targeted drug will automatically die because it cannot find the corresponding bacteria, and finally be excreted by the human body.

It can be said that it can quickly clean up the bacteria and viruses in the human body without causing any impact on the human body.

If this kind of thing can be broadcast live, it will definitely be a good thing for the benefit of human society.

In addition, there are many similar things.

Won would love to broadcast all of these things live.

But it's a pity that the working time left for him by this dog system can barely cope with the tasks, and there is simply not enough time to get these things.

This is a great pity.

In fact, if you really don't have time to live broadcast in the live broadcast, you can buy a pharmaceutical research and development company to do these things in the future.

But lack of energy and time is also a big problem.

This is the case with the previously acquired laboratories. Apart from throwing technology to them, Won has almost never taken care of it.

After all, most of the time, he is in the simulation space and has no time to manage it.

Han Won even has a feeling that people in the laboratory or the country have already guessed that the 'Yuanchu' laboratory has something to do with him.

After all, no one is an idiot. Anyone will investigate the sudden explosion of super technological power in a previously mediocre laboratory.

But since no one was looking for it, Han Yuan didn't pay much attention to it.

Maybe the above also has its own ideas.

After recovering from his conjecture, Han Yuan started to clean up the factory building.

The new space shuttle has been manufactured, and all that remains is to test it.

Functional chips prepared by lithography machines have been fully deployed on new aerospace vehicles.

Certain instruction information has been stored in these functional chips, which can be started according to the set program.

If it is in human society, it is naturally impossible to send a satellite to the sky so simple.

Because whether it is low-earth orbit or high-altitude orbit, there are different numbers of satellites.

Especially in low earth orbit, the number of satellites that can be accommodated is limited.

The launched satellite needs to be calculated first, and its accurate orbital route can be calculated before it can be launched.

Otherwise there may be collisions with other satellites.

Especially because there is currently no accurate way to divide orbital space internationally.

It has always been the principle that whoever goes up to that track first will get it.

After all, the ability to send satellites into the sky is generally something that can only be achieved by gathering national strength.

But in this way, some unscrupulous companies took advantage of this loophole and sent a large number of various small satellites into space, grabbing the orbit first.

Countless small satellites occupy a large number of low-Earth orbits, leaving other countries with no orbits to use.

Moreover, a large number of small satellites operating in orbit may be damaged in just a few years due to lifespan problems. Although most of them will fall down, a small number will pose a certain threat to other satellites or space stations.

This is simply a shitty thing.

After all, there are many astronauts doing experiments in the space station.

If it hits it, it will be destroyed.

But this is on the earth, and he is now in the simulated space,
Sending satellites into the sky on this simulated planet, Won doesn't need to think so much.

The new space shuttle is equipped with two different electric propulsion engines, one for use in the atmosphere.

The electromagnetic propulsion system is activated after the spacecraft carrying the satellite is sent to an altitude of [-] kilometers through the electric propulsion-free medium engine.

By switching the flight mode, the three electromagnetic propulsion engines output huge thrust to send the aircraft to low-Earth orbit.

Then just throw the satellite down.

There will also be functional chips, altitude locators and other things in the satellite. After detecting the altitude, it will automatically correct the altitude through the light sail and small electric propulsion engine to keep running.

Of course, this crude method cannot keep the satellite at a fixed altitude stably and for a long time.

It might draw an electrocardiogram in low Earth orbit, going up and down.

But after the altitude warning is triggered, the electric propulsion motors are automatically activated, pulling the altitude back to a point slightly above normal.

Moreover, the service life is not as high as that of precision satellites, and the general communication and broadcasting satellites are about five to ten years old.

And South Korea's requirement for the satellites it sends up is one year.

It doesn’t matter if you don’t fall or not after you complete the mission a year later, it’s even better if you don’t fall, if you can maintain communication, if you fall, you can make up for it.

And a new space shuttle can carry more than one satellite at a time.

Even though the space shuttle he designed is smaller than the Atlantis and Endeavor in the United States.

But the number of satellites that can be carried is actually more.

The former only needs to send the satellite up and throw it out, while the latter needs to carry astronauts into the sky.

It is inevitable that a lot of space will be wasted inside the space shuttle to ensure the survival activities of the astronauts.

The latter does not carry astronauts, and most of the space on the bottom floor can be used to place satellites.
