Super Battleship Reborn

Chapter 29 Space Elevator In Xiao Yu's plan, the county-level spacecraft should have a minimum weight of 100,000 tons and a length of at least 500 meters. Xiao Yu weighed his raw material reserves. After comprehensive calculations, he planned to build a 300,000-ton county-class spacecraft as his flagship. level is good.

Such a large spaceship can no longer be built from the ground. It is very simple, because the volume is too large and the mass is too large. After completion, with Xiao Yu's current level of technology, it cannot take off from the ground. If it were forced to take off from the ground, the ship's hull could be severely damaged.

If only the hull is damaged, it is still good. If it is replaced by a million-ton city-class spacecraft, or a ten-million-ton provincial class spacecraft, after completion, it cannot live in a massive star at all. Within the Roche limit, otherwise, it will be torn apart by the gravitational pull of the star.

Although Xiao Yu's spaceship is made of the strongest and toughest materials, it is hollow. Except for the outer shell, most of the interior is space. In this way, the overall density of the spaceship is not even comparable to that of water.

The so-called Roche limit refers to the limit distance at which a rigid body or fluid is not torn apart by its gravitational force when flying around a massive star. Taking the earth as an example, with Xiao Yu's current level of technology, if a ten-million-ton provincial spaceship is within 20,000 kilometers from the earth, because the earth's gravitational force on the hull of the spaceship is not balanced. , it will be torn to shreds by Earth's gravity. The reason why the artificial satellites launched by humans in the past were not torn apart was that they were too small and their materials were tough.

In science fiction movies, huge alien spaceships take off and land vertically from the earth, and they come and go freely. It is certain that they are civilizations that have mastered anti-gravity technology. Otherwise, with such a huge hull, they simply cannot do it. to this point.

With Xiao Yu's current technology, he is still a little short of mastering anti-gravity technology.

Although there is no way for the County-class spacecraft to be built from the ground, Xiao Yu found a solution early in the morning, that is, to build a dock in a synchronous orbit 2,000 kilometers away from Titan in order to build the County-class spacecraft.

But in this case, the transportation of materials has become a big problem. At present, only two spacecraft, the Hope and Dawn, are capable of traveling in space. However, compared with the hundreds of thousands of tons of materials needed to build the County-class spacecraft, the transportation capacity of these two spacecraft is still weak. a little.

At this time, the Institute of Materials Science and Technology established in advance came in handy. During this period of time, Xiao Yu has developed a new type of nano-polymer material whose strength is at least a hundred times stronger than that of steel.

Xiao Yu named this material Rope of Life, and he planned to use this material to make a space elevator.

Xiao Yu sent a huge army of robots to dig a pit hundreds of meters deep on Titan's equator, and buried a metal block weighing at least several thousand tons in the pit. Then he manipulated the Hope to come to the top of this pothole 2,000 kilometers (Note 1), and hovered there.

Then, a milky white rope-like object protruded from below the Hope. This thing is the highest manifestation of Xiao Yu's material technology, the rope of life. The rope of life with a radius of one millimeter can withstand a tensile force of nearly ten tons at a maximum. The toughness of this material can be imagined.

And the rope of life stretched out below the Hope has a radius of two centimeters. According to estimates, this rope of life can withstand a pulling force of nearly 4,000 tons.

A small nuclear fusion engine is installed at one end of the rope of life. After the engine is started, it will continuously pull it down toward Titan until it is pulled ten kilometers, and the rope ends.

A small nuclear fusion engine is also installed at the other end of the rope of life. These two nuclear fusion engines fix the ten-kilometer-long rope of life in the air.

With the rotation of Titan, it slowly rotates together.

The Hope then returned to its original location, re-installed with a rope of life. After connecting one end of the new rope of life with the original one, the rope of life continues to descend under the action of the nuclear fusion engine.

After more than 200 round trips, one end of the rope of life was connected to the pre-dug pit on Titan. Xiao Yu fixed it on the large metal block, and then manipulated the robot to move the large metal block. Buried. The other end is in space, and is fixed to another large metal block by the Hope.

In this way, a simple space elevator is completed.

The principle of this space elevator is very simple. When the speed of an object exceeds the second cosmic speed of the star, it will fly away from the star and never come back. And the speed of the space end of this space elevator has exceeded the second cosmic speed of Titan, but it is fixed by the rope of life. Of course, it will generate an upward pulling force, pulling the rope of life. Straighten.

And because Titan has its own rotation, through the rope of life, Titan will continue to accelerate the large metal block at the space end of the rope of life, so that his speed is always maintained above the speed of escape, and will never fall off. .

The most wonderful thing is that at the space end of the rope of life, due to centrifugal force, there will also be a force similar to gravity, so that when processing and building the hull, there is no need to suffer from weightlessness and inconvenience in construction.

The principle of the space elevator, in simple terms, is like a person vigorously tossing a large iron chain with an iron ball at the top. The iron ball wanted to fly, but it was fixed by the iron chain. Instead of flying, the iron chain would be stretched straight.

In this way, Xiao Yu can use this rope of life that will never fall to continuously transport supplies into space. Even Xiao Yu can make a pulley to pull supplies into space on the ground.

Of course, that's after the space elevators are all built. The current space elevator is just a prototype.

In the next few months, Xiao Yu carried out a lot of processing on this space elevator, including strengthening and thickening the rope of life, thickening its diameter to one decimeter, and installing a lot of equipment on it. A large number of robots were also stationed at the space end of the space elevator, and the construction of the dock was started.

It took Xiao Yu half a year to build this space elevator. At the same time as the construction of this space elevator, Xiao Yu started the construction of the other two space elevators. When the first space elevator was completed, the other two space elevators had also entered the late stage of construction.

There are a total of three space elevators, which provide Xiao Yu with powerful material transportation capabilities. On the ground, countless special steel materials, special materials, various built components, and various types of robots were transported one by one for the construction and consumption of the space dock.

At the same time, construction on the ground base has also started in full swing. In addition to the original base, Xiao Yu started the construction of three more bases. Several major ground bases are fully engaged in the construction of village and township-level spacecraft at the same time, and the three docks in space are fully committed to building county level. spaceship.

All kinds of materials were used out like flowing water, and what came back were three large docks, enough to build a 300,000-ton-class spaceship, and hundreds of village-class ships neatly placed there on the ground. Spaceships and dozens of township-class spaceships, the smallest of which are the size of Hope.

At the same time as the construction of the County-level spacecraft, Xiao Yu controlled all the hundreds of Village-level spacecraft to fly to Saturn, doing all he could to reserve materials. After all, after leaving the solar system, Xiao Yu would no longer be able to get even a piece of scrap iron to replenish.

At the same time as the construction of the spacecraft, the construction of a new generation of photonic computers has also been put on the agenda. During this time, Xiao Yu has updated research results on the photonic computer's architecture, operation mode, instruction set, etc. It is expected that after the new computer is built, Xiao Yu's computing power can be increased by five times on the original basis. . In this way, while manipulating the entire fleet of more than 1,000 spaceships, Xiao Yu has the ability to start the compilation work of The Sky of the Heroes and conduct various scientific researches.

At that time, the latest photon computer will be installed on the flagship and become the brain of the entire fleet, while the old photon computer will be installed on another county class spacecraft to serve as various auxiliary functions. , the calculation work that does not require Xiao Yu's direct intervention.

At this time, Xiao Yu no longer pays attention to sustainable development. He has attacked all methane lakes with black worms on Titan. Depending on the size of the lake, either nuclear strikes or conventional high-explosive ammunition strikes are used. In short, in addition to keeping some of the black worms for artificial breeding, Xiao Yu killed all the black worms he could collect, and then collected their corpses, part of which was used to build spaceships, and part of which was stored for future use. use.

The entire Titan is considered a bad luck. In the past few years, there will be a burst of fire from time to time on Titan, a mushroom cloud will rise, and the entire Titan will be turned upside down by Xiao Yu.

This is the last madness before leaving. Since I can't come back in the future, I'll leave a trace of myself here.

Xiao Yu thought so.

Three years passed in a hurry, and the construction of three county class spacecraft was completed. One thousand village class ships and seventy xiang class ships were also built.

Xiao Yu's long-awaited interstellar voyage will soon begin.

Note 1: Because Titan is locked by Saturn's gravity and rotates slowly, to build the space elevator mentioned in this article, the required length of the rope of life is at least about 20,000 kilometers. However, under the current construction ability of the protagonist, in order to be reasonable, it was changed to 2,000 kilometers. In addition, there must be many mistakes in the scientific theory in the article. students, don't get into it.

Also, there is only one chapter left for today. . .
