Don't say it, there really is.

Graphene.

A layer of graphene, a hundred or even a thousand times thinner than paper, can easily block bullets. Even to block all the armor-piercing bullets in service, it is enough to use a layer of graphene material less than a millimeter. Remember all, including armor-piercing missiles.

But the problem is that this thing cannot be produced on a large scale, and the production of graphene is still only in the state of laboratory preparation. The price of graphene to obtain a layer of atomic layers is staggering.

But even graphene, which has only one layer of atoms, is staggering.

Combined with the scientific and technological information in the starry sky machinery, I know that even if graphene can only be prepared in the laboratory, there are people who produce it at such a high cost, because the strategic value of this thing is too high.

It's a pity that graphene is a material that people from other worlds haven't researched why.

But they have developed a lot of strange scientific and technological products, such as a carbon fiber tube, a carbon fiber tube that can continue to expand and grow. It's similar to carbon fiber in Earth Technology, but it's much worse.

According to their scientific research and development, this carbon fiber tube is naturally absorbed and grown by carbon elements, and from the spore state of the fiber tube, it begins to absorb expanded carbon elements, and finally grows into a tube.

This kind of tube is very powerful, it can withstand hundreds or even thousands of times the atmospheric pressure, that is, if you put pressure in this tube, it will not burst the pipe at all, and the only thing that can explode is the interface.

Another characteristic is of course similar, that is, the tensile force, a millimeter-thick carbon fiber tube, the pipe wall is only about 0.1 millimeters, it can withstand thousands of times the atmospheric pressure, not to mention, it can also pull up tens of thousands of tons of things.

They just made a weird thing out of it, a space elevator.

Of course, it's not that they don't want to make anything else, it's that the carbon consumption of this thing is staggering. Take their standard carbon tube, which is five millimeters in diameter, has a wall thickness of 0.5 millimeters, and consumes 10 tons of coal per meter.

Yes, the material is against the sky, and the energy consumption is more ferocious.

In order to create a space elevator, they used up almost all the coal storage sites in Eurasia. Even the amount of carbon dioxide in the air has decreased dramatically, and the oxygen content has increased dramatically. The plants in their world have become much rarer, and it wasn't until they planted the Dark Energy Tree that the number of plants in their world began to increase dramatically.

And their research is also very interesting, the massive amount of carbon did not disappear out of thin air, but condensed like graphene. Countless elements of carbon eventually condense and grow into a tube.

This material is also very rebellious, similar to the familiarity of graphene, except that it cannot conduct electricity, everything else is familiar, it is almost the same, it is constantly cut, and it is still messy. The pull is amazing and powerful.

Yes, a 0.1 mm thick carbon fiber tube is straightened and cannot be distinguished by the naked eye, and it is difficult for even scanning devices to detect it, because it does not reflect electromagnetic waves at all.

Then pull one on the road, hehe, the people who walked by here were more neatly divided into two halves than they had cut with a knife.

That power is quite touching.

I remember that they once did an experiment and weaved a cloth out of this material, and as a result, they were stunned that no weapon could penetrate it. It is not burned through until it is burned with a high-temperature laser.

And not everything can set them on fire, because the material has a ignition point of more than 6,000 degrees.

Since the birth of this super material, they have basically said goodbye to other materials. Because it's not as good as this thing.

But it's still that feature, the carbon consumption is too amazing, it can't be produced on a large scale, because the production is very easy, as long as it is configured through a special configuration method, this thing can absorb all the solid carbon elements including coal, charcoal and even dry ice, the more it absorbs, the more it grows, the ratio of ten to one grows, the diameter of the pipe is 10, the diameter wall is bound to be 1, the length is 1000 times that of the pipe, and there is no way to change.

Two tubes of almost the same thickness are connected together, sprinkled with some toner, and in a short time, they are fused together, and even glue is saved.

Six standard carbon fiber tubes of the same thickness can firmly fix the billion-ton space station in the earth's orbit. Numerous layers of deceleration layers are wound around the outer walls of these tubes, and finally layers of electromagnetic acceleration platforms are encased. From the ground to space, it only takes ten minutes. That's called a convenience.

But it took them nearly a hundred years to build four spaceships that could sail to other galaxies, and they were the fastest, infinitely close to the speed of light.

As for the so-called micro-curved transition technology, they have studied it for more than a hundred years and have not come up with a fart.

It seems that Lao Mo once gave a feasibility report on the manufacture of engines from cold iron. For large-scale engine technology, the technical blockade of various countries is very eyed, even if the star company is extremely strong, it cannot be touched. But building jet engines for small airplanes is not a problem at all.

Even the turbofan engine is not a big problem, it's just a question of whether they want to build it. And really don't want to build it? How is it possible, if you can sell military hair on the black market, it must be a very, very profitable business. It's just that no one dares to touch that red line.

There is no way, but to build small engines, it seems that certain models of missile engines are made by Star Machinery.

Suddenly, Xiao Chu remembered a strange poster on a forum.

The strange thing about this post is that the author of this post is a missile designer, but the place where he posted is an in-depth communication website for model aircraft enthusiasts. said that his post was a god post because this thing had a big brain, using the engine of an air-to-air missile to assemble a model airplane, and then this product made a model airplane that can break through three times the speed of sound.

It's weird enough, what's even more strange is that this product has restored an engine that the old hairymen eliminated, and it is still a super strange engine.

Because this engine was really eliminated by the old Maozi themselves, the reason is very simple, it is not safe, theoretically, this engine can push the missile to a magical speed of Mach 10. However, the engine was short-lived, as the cooling system simply could not keep up with the heating of the combustion chamber.

Supposedly, the only thing that can achieve this thrust is a scram-fired supercharged jet engine with liquid mixed oxygen. However, some of the most brainy Maozi thought of two ways to increase its thrust, so that its thrust reached 40 times that of ferociousness. What's even worse is that this is also a turbocharged vectoring engine. That's right, aside from the fact that it's not too big, the energy efficiency of this engine is simply amazing.

Then some people will say that the most advanced aircraft engines now have only a thrust-to-weight ratio of more than ten times, and engines with a thrust-to-weight ratio of 40 times, are they really fake?
