Technology's opening live broadcast to build rockets

"Start the 304th nuclear fusion thruster simulation!" In the technology simulator, Du Xingyu tirelessly carried out the simulation.

Nuclear fusion thrusters are not simply a matter of replacing the nuclear fission reactor in the original nuclear power thruster with a nuclear fusion reactor.

Nuclear fusion has more energy output, which requires a power device that can withstand more energy and has higher power.

This is another huge test for the structural design of the device and new materials.

"The design concept should be the same as the hybrid propulsion unit of the Mars spacecraft. Nuclear thermal power plus nuclear electric plasma thrusters ensure flight status in both the planetary atmosphere and space environments at the same time."

"The output power of a combined power unit is too low... It is designed as a main power unit and four auxiliary power units. It uses a nuclear fusion reactor as the energy source and outputs five power units at the same time to produce a space battleship weighing tens of thousands of tons. The power to lift off..."

Du Xingyu continued to modify and simulate. This is the most powerful thruster he has ever designed.

The maximum load of previous spaceships was only more than a thousand tons, but this time it has increased dozens of times!

Technology simulator: "1+4 combined nuclear fusion thruster is being simulated..."

In Du Xingyu's mind, a spherical tokamak device is undergoing a stable fusion reaction. The output energy is first converted into thermal energy, heating the working medium and oxidant, and generating huge propulsion force.

The model space battleship began to take off and rushed out of the atmosphere. The power unit was promptly replaced with a nuclear plasma thruster. The nuclear fusion energy began to generate strong magnetic and strong electric fields, controlling high-temperature plasma jets, forming a faint blue tail flame behind the battleship. , allowing the battleship to continue accelerating in space.

…

The design and manufacturing of space battleships is definitely a super project that exceeds that of space elevators. After all, there is a certain amount of previous engineering experience for reference in the construction of artificial islands, towers, space stations, etc. for space elevators.

But space battleships, this is the first time in human history!

When experts from all over the world come together, they will also face various problems. In order to build the first space battleship that flies into the stars, China built a huge "super dock" on the northern coast, Longgang.

The source of funds for building space battleships comes from the energy benefits brought about by the use of controllable nuclear fusion technology in social production!

Yes, after the successful test of the "Golden Crow" device, China immediately began the commercial promotion of controllable nuclear fusion, and began to build controllable nuclear fusion energy stations in China and around the world.

The use of new energy has brought the foundation for the development of the entire human society. In the past few years, due to breakthroughs in various technologies, civil technology has also entered a period of rapid development.

Economic growth and cooperation from countries around the world have provided the economic foundation for building space battleships.

The root cause of all this lies in Du Xingyu. If he had not used technological simulators to overcome these technical problems, I am afraid that humans would have been thinking about how to escape from the earth by now.

…

Three years later, Longgang Shipyard.

The huge space battleship hull is being spliced. The hundreds of meters long hull is being set up in the super dock. Its appearance is silver, and its edges are like sharp blades, as if it can cut time and space.

At the top is a sharp "arrow". This shape also has a special meaning. A brand-new weapon system will be released from here.

This is also Du Xingyu's main work after completing the nuclear fusion thruster, the design of space weapons.

In space, conventional weapon methods have lost their effect. Long-distance space nuclear explosion technology and energy weapons are the most effective ways to strike.

Those nuclear weapons experts who have space hydrogen bombs have a way to solve it. Du Xingyu mainly designs "laser weapons", which use the huge energy generated by nuclear fusion to arrange ultra-high temperature laser arrays in the battleship to form a laser that shoots out in a straight line at the speed of light. It can almost Any metal melts, producing ablation, shock waves and radiation.

This kind of destructive power even exceeds that of a space nuclear explosion in terms of single-point destructive power!

In addition to the main hull and internal mechanisms, the space battleship is also equipped with other weapons and ancillary equipment. For example, super missiles with intra-atmospheric strike projection capabilities covering the entire planet, supporting small space fighters, and some newly developed military robots.

"The splicing of the hull and subsequent overall testing will take two months, which is the fastest time possible." Hu Chun, the chief engineer in charge of the hull engineering, reported to Du Xingyuhui.

Three years is already a long time for mankind to build its first space battleship. Almost all of the world's top military industrial enterprises and high-tech companies participated in this manufacturing.

"Two months, the progress must be accelerated, but the construction quality must be guaranteed." Although he had said it many times, Du Xingyu couldn't help but warn him.

"I guarantee it with my life!" Hu Chun said seriously. He was an engineer with a military background, and he was unambiguous in his mission.

…

While the earth is busy building space battleships, humans are constantly launching detection satellites into the solar system, trying to find traces of unknown enemies, but unfortunately nothing has been found so far.

What humans are most concerned about is still the Death Star!

Now they have been able to confirm that this is a kinetic energy weapon launched by an alien civilization!

After sacrificing three Predictor detection satellites, they speculated that this "kinetic energy weapon" was very simple.

Apart from a large asteroid thruster and laser defense system, it has almost no other devices.

But such a simple and unpretentious weapon, relying on the mass and speed of the Death Star, can bring powerful kinetic destructive power, making the entire human race struggle!

"We have figured out the laser defense device on the Death Star. The Predictor 5 detection satellite will definitely not be destroyed. This time we can get more information!" The Human Alliance's Death Star observation team is conducting an investigation on the Death Star. Conduct a new round of observations of stars.

A detection satellite approached the Death Star again. Eight years had passed since Du Xingyu predicted the Death Star. During this period, the Death Star had flown a distance of two billion kilometers and was still half way from the earth.

In the photos sent back by the detection satellite, the thruster behind Nephew was still cold. The detection satellite gradually approached and tried shooting from various angles. But this time, the laser weapon did not appear.

"Laser weapons also consume a lot of energy!" A space military expert said excitedly, "Our guess is correct, the energy inside the Nephew has been exhausted! Now laser weapons cannot be used!"

"Great, then our next step can be to launch a small detector into the thruster to check the situation!" Everyone was overjoyed. The survival time of Predictor 5 has been more than three times longer than the previous four generations of detection satellites!

Just as they were preparing to send new mission instructions to Predictor 5, a new set of photos came.

In the photo, the propeller of the Death Star, which has been dormant for eight years, is emitting blue flames and has been activated!

This is not a flame, but a scene where a large amount of material is burned into plasma and ejected.

The Death Star is accelerating again!

"It still has energy!" Everyone felt like they had fallen into an ice cave, trembling all over! At first, they all guessed that the Death Star had no energy and could no longer accelerate.

But now, the facts tell them that this is just a beautiful delusion, and the Death Star can still accelerate!

This means that it will hit the earth faster and in a shorter time! The kinetic energy carried will be doubled again!

The Predictor 5 detection satellite also failed and was penetrated by a laser, but it had already sent back enough information.

The Death Star is accelerating again!

"It's over, it's really over this time!" An observer's face turned pale, knowing full well that the disaster would intensify. Hiding enemies is like playing tricks on them!

"Do we still have a chance to resist?" The shadow called "despair" hangs over everyone's heart.

The news was quickly reported, and the Human Guardian Alliance decided to hold an emergency meeting.

"If we keep accelerating like this, our asteroid impactor won't be able to stop the Nephew!" Some people were extremely anxious.

Du Xingyu was also full of worries, but he forced himself to calm down. After so many years, he had developed the composure to remain calm even if the mountain collapsed.

"Don't be anxious, I still maintain my previous point of view." Du Xingyu said, "There is not much power energy left in the Death Star!"

"Starting the Nephew's thruster requires consuming energy and ejecting matter. If its power source was sufficient, it would have accelerated long ago, and the earth would have been destroyed! According to the radiation detection situation of the Predictor 5, the radiation inside the Nephew is The radiation is not high. Even if there are radiation protection devices to block it, it means there is not much energy storage."

"The reason for this, I guess, is that the enemy behind the scenes wants to give us a blow and make us disorganized."

"The acceleration of the Death Star will not last long. After a while, it will definitely stop!"

"Now we can only speed up our plans and wait." The members felt a deep sense of powerlessness.

Du Xingyu's guess was not wrong. According to observations from the space telescope, Nephew stopped accelerating after a week of acceleration and continued to fly by relying on inertia.

Even so, it will hit the earth two years earlier, and the kinetic energy it carries will increase significantly.

…

Somewhere in the UK, in a private house, an old man with gray hair and a haggard face was writing at his desk.

He is a famous astronomer and a member of the Nephew Observation Team of the Human Guardian Alliance, Hansen.

"The Death Star is accelerating again, leaving us less and less time... I don't know if humans still have a chance to deal with it. Various evidence shows that in addition to the Death Star, we also have to deal with aliens who don't know where they are. Civilization... They are like demons about to come, torturing my soul every day and night. I can't bear it anymore... My children, please forgive me for not being able to continue to accompany you. I want to be with you very much. Say goodbye, but the news cannot be known to the world, otherwise they will suffer torture and suffering like me every day..."

Hansen finished writing the letter and was about to throw it into the burning fireplace, but when he was about to stand up, his eyes darkened and he fell to the ground.

Hansen, passed away! The letter he left behind was still on the table with the ink still wet.
