The study of controlled nuclear fusion jishu has been carried out by mankind for decades. During these periods of time, although human beings have not broken through the shackles of this jishu, they have also accumulated a huge amount of research data in a large number of studies, which provide a very important reference for Xiao Yu.

Especially when Jupiter and Moon collided, the phenomenon that occurred on Jupiter taught Xiao Yu a very important lesson.

On top of these foundations, with the powerful computing power of the photonic computer, Xiao Yu finally got a very important breakthrough today.

At Base 2, in the controlled nuclear fusion laboratory, there is a huge glass box covered with various lines that will produce a specific magnetic field. Under the constraints of this magnetic field, in the center of the glass box, there is a very bright and dazzling point of light hanging in mid-air, radiating a huge amount of light and heat all the time, making it impossible for people to look directly.

They are undergoing nuclear fusion, from deuterium and tritium, fusing into helium. In this process, a part of the mass is converted into energy.

Xiao Yu allocated ten percent of his computing power to pay attention to this, and quickly carried out various calculations.

Looking at the experimental data, Xiao Yu was inexplicably excited. He had waited too long for this moment.

Relying on chemical fuels for interstellar voyages is unrealistic. Because its energy efficiency ratio is too low, if you really have to rely on chemical fuels to go from the solar system to the four star systems of Tianyuan, Xiao Yu estimates that he will have to build a kilometer-level spaceship, and fill more than 90% of its space with fuel to barely be enough.

It can be said that controllable nuclear fusion jishu is a stepping stone to open the door of interstellar navigation, without controllable nuclear fusion, relying on chemical fuel alone, Xiao Yu will be immortalized in the solar system, and he can't get out.

"Well, a new generation of fusion-powered spacecraft, start building!"

Xiao Yu started a new jihua. He wanted to build an epoch-making spaceship that used the latest Jishu in terms of power systems, structural materials, and control systems.

All the construction carried out in the early stage is to serve this purpose.

The huge special steel smelting blast furnace is constantly flowing with dark red molten steel. After condensation, the molten steel will be turned into ingots for processing. However, Xiao Yu added another process before condensing.

This process is to expose the molten steel to radiation from "No. 1" for about five minutes before condensing.

After Shiyan, Xiao Yu found that when the metal is in a high-temperature liquid state, the radiation from "No. 1" can achieve the maximum performance improvement with the minimum radiation intensity. Therefore, poor "No. 1" was caught here by Xiao Yu and served as a coolie who sold his blood.

These five minutes of radiation exposure are enough to increase the properties of these special steels by more than three times.

In the smelting process of these steels, Xiao Yu also added the corpses of those black insects according to a certain proportion, so that these steels have been greatly improved in terms of heat insulation and radiation resistance.

Xiao Yu is doing his best to build the best quality materials. These materials, after being processed in the equipment manufacturing room, will be turned into parts for this great, epoch-making spacecraft.

In the huge assembly hall of the main site, a variety of components from at least hundreds of machine building rooms are gathered. At least hundreds of robots were busy here, assembling various precision components one by one, and it took half a year to build the spaceship.

This is a saucer-shaped spacecraft with a diameter of 20 meters and a height of about 5 meters, the power system uses a nuclear fusion engine, the control system uses the latest photonic computer, and the construction materials are the best quality steel that Xiao Yu can make. This is a spaceship that gathers Xiao Yu's hard work, and this is the most advanced spaceship that Xiao Yu can build with his current technology.

In order to build this spacecraft, the radiation intensity of "No. 1" was directly reduced to 30 percent of the maximum radiation intensity, and 70 percent of the radiation intensity was used. Nearly 200 tons of carcasses of black bugs have been used, accounting for 30 percent of the current reserves.

Although the consumption is so huge, Xiao Yu believes that it is worth it. Even if the radiation intensity of "No. 1" is used up, it can go to Jupiter to capture it again, and as for the corpse of the black bug, Xiao Yu is not worried. During this time, Xiao Yu found this creature in at least a thousand larger lakes on Titan, and its total storage is expected to reach millions of tons, so many reserves are enough for Xiao Yu to build a large fleet.

Today is the day of the test flight of this spacecraft.

Xiao Yu stopped most of the construction progress, and allocated at least 40 percent of the computing power here - 40 percent of the total computing power of the photonic computer, which is almost equal to the total computing power of all supercomputers on the earth.

"Make sure nothing goes wrong." Xiao Yu thought silently in his heart, "You carry my hope for interstellar voyages." Let's call you the Hope. ”

The mass of the Hope is about 3,000 tons, and the spacecraft of this level is divided into the "Village" class spaceship by Xiao Yu. If a spaceship of more than 10,000 tons is built in the future, it will be divided into the category of "township" class spacecraft, and so on, with the increase of tonnage, until several different categories such as "county level", "city level", "provincial level", "national level" and so on.

The village-level spaceship, the Hope, under Xiao Yu's full attention, a light blue flame erupted from the bottom of the spaceship, and slowly left the ground.

Yes, the Hope spacecraft does not need a rocket to send it into interstellar space, but has the ability to take off directly. Because its powerful and efficient power system can provide it with enough long-lasting and strong enough power, and advanced material technology ensures that it is not designed according to aerodynamics, nor will it be torn apart by the gravitational force and air resistance of the planet in high-speed motion.

Ten seconds later, Hope was three thousand meters above the ground. The huge friction caused its shell to flush slightly, and the temperature was estimated to be above 800 degrees Celsius. But Xiao Yu was not worried at all. The ship's hull, made of special steel mixed with the corpses of black bugs, is still a small part of the temperature to withstand.

It was getting faster and faster, and a minute later, Hope was 100 kilometers above the ground and reached Titan's orbit, but he was still accelerating.

At this time, the communication between Xiao Yu and Hope completely relied on the twelve Ares satellites launched before.

Xiao Yu steered Hope out of Titan, and came to a sharp brake in the middle of the stars, and the speed suddenly decreased from three kilometers per second to almost stationary.

"Spacecraft Overload Test...... Pass. ”

The acceleration of gravity on the Earth is 9.8 meters per second, which means that on a spaceship that accelerates at a speed of 9.8 meters per second at all times, a person feels the same gravity as on the Earth because of inertia.

If the spacecraft accelerates at a speed of nineteen.6 meters per second, the person will feel twice the gravity of the Earth.

That's overload. A trained super-pilot, which can withstand ten times the overload, that is, the limit of the human body's endurance, is an acceleration of ninety-eight meters per second. Beyond this acceleration, the human body will suffer irreparable damage and even death.

And the ship's hull also has an overload limit that it can bear. Ordinary large aircraft can withstand a maximum of about 20 times the overload, beyond which the fuselage will be torn apart by inertial forces and air resistance.

Before the destruction of the earth, the spacecraft built by humans could withstand an overload of about 30 to 40 times, that is, a maximum acceleration of 400 meters per second, and if this limit was exceeded, the spacecraft would also be torn apart by inertial forces.

Xiao Yu had just tested his spaceship. The test results show that it can withstand an overload of about 230 times the maximum! In other words, Xiao Yu's spaceship can withstand a maximum acceleration of 2,200 meters per second!

This means that the Hope spacecraft can change from a stationary state to a state of running 2 kilometers per second within one second, and can also stop instantly during a high-speed operation of 2 kilometers per second.

This means extreme flexibility. And such strong flexibility, coupled with Xiao Yu's terrifying calculation speed, even if there are tens of thousands of people and tens of thousands of guns firing at the same time at the Hope, Xiao Yu can control the Hope and completely dodge the bullet shooting in just a few seconds.

After the anti-overload test, Xiao Yu carried out another test.

"Conventional Fuel Reserves, Maximum Operating Speed Test."

In astronautics, the only thing that consumes fuel is acceleration, deceleration, and changing course. Flight in peacetime mainly relies on inertia, and this stage does not consume fuel.

The fastest spacecraft ever built to be powered by chemical fuel or nuclear fission is Voyager 1, which has reached a speed of about 18 kilometers per second relative to the Sun. Weishenme can no longer increase its speed? Precisely because of the problem of fuel restrictions. Xiao Yu once reached a speed of 60 kilometers per second before reaching Titan, because he received additional fuel replenishment.

What Xiao Yu has to test now is how fast the Hope can support with a regular amount of fuel.

The tail of the Hope erupted with powerful blue flames and began to accelerate at a terrifying speed, faster and faster, faster and faster.

"Conventional fuel reserves, maximum operating speed...... Three hundred kilometers per second! Conventional fuel reserves can support Hope to make more than six such accelerations and decelerations! If you don't consider the deceleration problem, only consider the maximum power of the engine, and if you keep accelerating, it can reach a speed of 1,000 kilometers per second when the fuel is exhausted! ”

This data shocked Xiao Yu.
