Super Battleship Reborn

Chapter 29. Space Elevator In Xiao Yu's planning, the "county" class spacecraft must have a minimum weight of 100,000 tons and be at least 500 meters long. Xiao Yu weighed his raw material reserves. After comprehensive calculations, he planned to build a 300,000-ton-class "county" -class spacecraft. As his flagship, the remaining two might be a little smaller, and 200,000 tons would be built. Good grade.

Such a large spaceship can no longer be built from the ground. It is very simple, because the volume is too large and the quality is too large. After the completion, Xiao Yu's current level of technology has no way to take off from the ground. If you take off from the ground, the ship's hull may be severely damaged.

If only the hull damage is good, replace it with a "municipal" class ship of the million-ton class or a "provincial" class ship of the 10-million-ton class. After it is completed, it cannot be in the mass of a star Roche's limit, otherwise, it would be shredded apart by the gravitational pull of the stars.

Xiao Yu ’s spacecraft, although it ’s made of the strongest and toughest material, is hollow, except for its outer shell. Most of the space is empty, so the overall density of the spacecraft is not even better than water.

The so-called Roche limit refers to the limit distance that a rigid body or fluid cannot be shredded by its gravity when flying around a massive star. Take the earth as an example, taking Xiao Yu's current level of technology, a "provincial" class spacecraft with a capacity of 10 million tons, if it is within 20,000 kilometers away from the earth, because the gravity of the space around the ship's hull is not balanced. , It will be torn into pieces by the gravity of the earth. Previously, artificial satellites launched by humans were not shredded because they were too small and made of tough materials.

In science fiction movies, huge and extremely alien spacecraft take off and land vertically from above the earth, and they can move 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.

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

Although there was no way for the "county" class spacecraft to be built from the ground, Xiao Yu found a solution early on, that is, to build a dock in a synchronous orbit 2,000 kilometers from Titan to build a "county" class ship.

这样 But then, the transportation of goods becomes a big problem. At present, only the spacecraft Hope and Shuguang are capable of shuttle in space, but compared with the construction of the "county" class spacecraft, which requires hundreds of thousands of tons of materials, the transportation capacity of these two spacecraft is still weak. A little bit.

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

Xiao Xiaoyu named the material "rope of life", and he planned to use this material to make a space elevator.

Xiao Yu sent a large number of robot corps to excavate a large pit several hundred meters deep on Titan's equator. A metal block weighing at least several thousand tons was buried in this large pit. Then, manipulating the Hope came to this pothole two thousand kilometers (Note 1) and hovered there.

Then, a milky rope-like object protruded below Hope. This thing is the highest embodiment of Xiao Yu 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 most. The toughness of this material can be imagined.

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

小型 A small nuclear fusion engine is installed at one end of this rope of life. After the engine is started, it will pull it continuously toward Titan, and it will not reach its end until after ten kilometers.

小型 A small nuclear fusion engine is also installed at the other end of the rope of life. These two fusion engines fix the ten-kilometer rope of life in the air, turning slowly along with Titan's rotation.

Hope then returned and re-installed a rope of life and came to its original location. After connecting one end of the new rope of life to the original one, the rope of life continued to drill down under the action of the nuclear fusion engine.

After more than two hundred round trips, one end of this rope of life was connected to Titan's pre-digged big pit, and Xiao Yu was fixed to the big metal block, and then he manipulated the robot to place the big metal block Buried well. The other end is in space, and the Hope is fixed on another large metal block.

That's it, a simple space elevator is finished.

The principle of this space elevator is very simple. When an object moves faster than the second universe speed of the star, it will fly away from the star and never return. The space end of this space elevator has exceeded Titan's second universe speed, but it is fixed by the rope of life. Of course, it will generate a pulling force to lift the rope of life. Straighten.

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

The most wonderful thing is that at the space end of the rope of life, because of the centrifugal force, a force similar to gravity is also generated here. In this way, when processing and constructing the hull, there is no need to suffer from weightlessness and inconvenience of construction.

原理 The principle of a space elevator is, in simple terms, like a person vigorously throwing a large iron chain with an iron ball at the top. The iron ball wants to fly, but it is fixed by the iron chain and can't fly, but it will straighten the iron chain.

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

Of course, that's what happened after the space elevator was all built. The current space elevator is just beginning to take shape.

In the next few months, Xiao Yu did a lot of processing on this space elevator, including strengthening and thickening the rope of life, thickening its diameter to a 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 to begin construction of the dock.

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 work on the construction of the other two space elevators. When the first space elevator was completed, the other two space elevators were already in the late construction stage.

A total of three space elevators provided Xiao Yu with a powerful material transportation capacity. On the ground, countless special steel, special materials, various built-in components, and various types of robots were carried up one by one for the construction of the space dock.

At the same time, the construction of the ground base has begun in full swing. In addition to the original base, Xiao Yu started construction of three more bases. Several major ground bases are working on the construction of "village" and "township" spaceships. The three docks in space are building the "county" level. spaceship.

All kinds of materials are used like running water. In return, there are three large docks that can build a 300,000-ton-class spaceship, and hundreds of "village" -class ships placed there on the ground. The spacecraft and dozens of "township" class spacecraft, the smallest of which are as large as the Hope.

At the same time as the construction of the "county" class spacecraft, Xiao Yu controlled all of these hundreds of "village" class spacecraft to fly to Saturn, and fully carried out the work of material reserve. After all, leaving the solar system, Xiao Yu can no longer get even a piece of scrap iron to supplement.

At the same time as building the spacecraft, the construction of a new generation of photon computers has also been put on the agenda. During this time, Xiao Yu had updated research results on the architecture, computing mode, and instruction set of the photon computer. It is expected that after the new computer is completed, 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 spacecraft, Xiao Yu was also able to start the editing and editing of the "Qing Ying Cang Qing Lu" and conduct various scientific research.

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 spaceship, UU Reading www.uukanshu. com performs various auxiliary calculations that do not require Xiao Yu's direct intervention.

At this time, Xiao Yu also stopped focusing on sustainable development. He hit all methane lakes with black insects on Titan. Depending on the size of the lake, either nuclear strikes or conventional high-explosive ammunition were used. In short, in addition to leaving some black worms for artificial breeding, Xiao Yu killed all the black worms that he could collect, and then collected his corpses, some of which were used to build spaceships, and some were reserved for future use. Use.

The entire Titan can be regarded as a mold. In the past few years, Titan will have a burst of fire and a cloud of mushrooms from time to time. The entire Titan was turned upside down by Xiao Yu.

This is the last madness before leaving. Since you can't come back later, leave here and leave a trace of yourself.

Xiao Xiaoyu thought.

In the past three years, three "county" class spacecraft were completed. A thousand "village" class spaceships and 70 "township" class spacecrafts have also been constructed.

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

Note 1: Because Titan is locked by Saturn's gravity and its rotation is slow, the length of the life rope required to build the space elevator mentioned in the article must be at least 20,000 kilometers. However, under the protagonist's current building capacity, for reasons of reason, it has been changed to 2,000 kilometers. In addition, there must be many mistakes in the theory of science in the article. I hope you don't take it seriously and just have fun. Classmates don't delve into it.

Also, there is only this chapter today. . .
