Technology's opening live broadcast to build rockets

Technology Simulator: "A new branch of technology has been opened, energy - controlled nuclear fusion."

The energy branch is a super category, and controllable nuclear fusion is only a small category in the technology simulator. Even so, gray patterns of many types of controlled fusion technology appeared on the simulator.

"Stellarator Magnetic Confinement Fusion Device."

"Tokamak fusion reaction device. (Branch one, ring-shaped tokamak device; branch two, spherical tokamak device.)"

"Inertial Confinement Fusion Energy Releaser."

"Nuclear fusion energy conversion device."

…

Under this category, the first is to realize controllable nuclear fusion devices, and then are the machines for various energy conversion and release.

After controllable nuclear fusion is completed, there will be a basis for research on subsequent fusion generators, fusion thrusters, fusion laser transmitters, etc.

Based on the basis of international thermonuclear fusion research, Du Xingyu first set the goal of scientific and technological simulation on the tokamak fusion reaction device.

"The ring-shaped tokamak device is undoubtedly the most researched and mature nuclear fusion device now." Du Xingyu analyzed the information he obtained. It is a series of complex electromagnets surrounding a donut-shaped container, some of which are horizontal. On top, some are vertical. A tightly wound electrical coil, called a solenoid, travels down through the hole in the donut. These combined magnetic fields squeeze the plasma toward the center of the tube, causing it to slowly twist in a spiral as it wraps around the coil.

However, plasma is difficult to control. Trapping it is like trying to squeeze a balloon with your hands: it always puffs up between your fingers. The hotter the plasma becomes, the more gas bound by the magnetic field expands, twists and tries to escape. Most fusion research over the past 60 years has focused on how to control the plasma.

To achieve stronger binding force and control, a larger ring-shaped tokamak device must be built.

This is a problem that must be solved for Du Xingyu, who wants to build a nuclear fusion engine.

"In comparison, the spherical tokamak device can achieve higher circumferential specific pressure in a smaller volume, and has better stability and binding force. It is just more difficult to manufacture."

"Invest one hundred thousand energy points and start the first simulation of the spherical tokamak device!" Du Xingyu started with the existing data and started the simulation.

In reality, it would take at least several years and tens or even hundreds of billions of dollars to build such a device. But in Du Xingyu's technology simulator, it only takes one billionth of a second to complete.

In the simulator, he has built a model of the spherical tokamak device proposed by Oak Ridge National Laboratory in Tennessee, USA, and started running the model and recording data.

In the process of technological simulation, Du Xingyu has long been accustomed to failures and mistakes. It is through mistakes again and again that he can obtain more data information and make improvements at the lowest cost and highest efficiency.

This is destined to be a huge project, and Du Xingyu still doesn't know which device, what kind of structure, materials and various auxiliary devices are the most suitable choice.

In the process of Du Xingyu's learning and experimentation, the "Death Star Crisis Response Plan" was also carried out amidst difficulties and twists and turns.

Before the space elevator is built, it will be impossible to transport too many materials to space, and the construction of a space port will be out of the question.

But this does not prevent designers and engineers from designing the spaceport and manufacturing components. The spaceport will be modular in design, just like the space station.

They first launched the cornerstone modules. These cornerstone modules also have power systems and will maintain a synchronous orbit with the Tiangong Space Station and act as counterweights for the space elevator.

In addition, military experts from various countries are also studying and discussing the design of space battleships and the construction of outer space defense systems.

Several major countries are sparing no effort to build heavy-duty transport rockets and reusable spacecraft, develop the moon, and explore Mars. China has absolute dominance because of its leadership in space technology.

Today, among the spaceships under construction, apart from those independently developed and manufactured by China, they are also jointly developed by China and other countries.

…

In the first year after mankind discovered the Nemesis Planet, the world structure underwent earth-shaking changes. The Human Guardian Alliance led by China was established, and the super project of the "Meteor Star Project" was started!

After experiencing a period of panic, uneasiness, and discomfort, people all over the world are beginning to get used to this kind of life.

This year, Du Xingyu had no leisure time. Even during the Chinese New Year, he only went home and had a reunion dinner before rushing to the institute.

Another five months passed in a hurry in the second year, and in early June, the first super project "Ladder to Heaven" finally received good news.

"The construction of the Tianti ground station, including the Tianti tower, has been completed. Penglai Island is still being expanded, but it will not affect the Tianti project." Chai Boyan, chief engineer of the Tianti ground station, reported the situation to Du Xingyu.

"Very good, thank you for your hard work!" Du Xingyu said happily, "Japanese and Korean chemical groups have also made more than 40,000 kilometers of carbon nanotube cables, and German companies have prepared the car, space station and counterweights. alright."

“Then we can proceed with the main body splicing.”

All parts of the space ladder have been manufactured earlier than expected, and the final step of manufacturing will come, with the main bodies being spliced ​​together.

Among them, the length of carbon nanotubes is longer than the 36,000 kilometers of the space station, and they are still being manufactured and synthesized. This is both for backup and to extend the height of the space elevator from the Tiangong Space Station to the near-Earth spaceport.

The car manufactured by a German company can not only be connected to carbon nanotubes and powered up to climb, but also carries rocket thrusters and parachute safety equipment, which can ensure the safety of people and materials in the car in the event of an accident on the cable.

The laying of cables determines whether the space elevator can be successfully "opened to traffic". Therefore, Du Xingyu plans to supervise the work personally so that if any problems arise, he can solve them in time.

Penglai Island has undergone a 180-degree change compared to a year ago. The original blue sea has now become a beautiful artificial island of more than 1,000 square kilometers!

On the artificial island, you can also see the engineering team busy with construction. The central part of the artificial island is the ground station of the ladder.

The process of building the ground station has been broadcast live around the world. According to statistics, at least one billion people around the world have seen this live broadcast or related videos!

Although the live broadcast room is now closed, people still pay attention to Penglai Island and Tiandai.

Du Xingyu came here for the first time after the ground station was built. He saw the tower with a height of 14 kilometers above the ground at a glance!

This is the tallest tower in human history so far! In order to maintain stability, its lower part is entirely poured with reinforced concrete, and the underground part is a full 1.5 kilometers deep!

When building the island, more than a hundred engineering teams were used at the same time just for the bottom of the tower, with engineers and experts from more than ten countries providing guidance and research!

Now, looking from the ground, it looks like a majestic pagoda holding the sky, standing on Penglai Island, with the top of the tower pointing straight into the endless sky!

In the new week, please vote for recommendations, favorites, and rewards. If nothing else, it should be on the shelves this Friday.
