Chapter 273 Planetary Battleship

After the Federation received the Olive Branch Civilization materials from the 椘, it has already started to manufacture planetary battleships.

And now it has actually been 10,000 years since then.

The situation is actually much more difficult than Yan Xia expected when he got the materials, because they have invested too much expectation in the planetary battleships. If the planetary battleships are just a little bigger than the dwarf planetary battleships, then what is the use?

In terms of energy, planetary battleships strive to pursue higher sustainable energy.

The original plan was to store a huge amount of positive and antimatter, but the development of antimatter requires energy to replace, so the antimatter energy in the Federation is actually very limited. It may be able to support war use, but this is completely different from working as a propeller.

The energy of 1g of antimatter and 1g of matter annihilates is 1.8*10^14 joules, which is equivalent to 43,000 trillion tnt equivalents. 1kg is equivalent to 43 million trillion tnt equivalents. The annihilation of 1 antimatter and 1 matter is equivalent to 43 billion tnt equivalents. The annihilation of 10,000 antimatter and 10,000 matter is equivalent to 430 trillion tnt equivalents, which is roughly equivalent to the impact of 5 to 6 asteroids that wiped out the dinosaurs on Earth.

How much antimatter is needed to propel a planetary battleship?

The answer may be 1 million tnt.

Accelerating a planetary battleship to the third cosmic speed may require 50 million tnt or even more.

How much antimatter is needed to accelerate a planetary battleship to a speed of 30,000km/s or even the current requirement is close to 40,000km/s?

It is hard to calculate, maybe 50 trillion tnt.

This is too much, it can be said that one launch is enough to consume all the inventory of the Federation.

Therefore, the second plan still continues the previous idea, which is to insert a planet into the interior of the planetary battleship, use the gravity of the planet to provide continuous energy, and at the same time, use gravity to assist electromagnetic force to set up a joint tokamak device inside the planet, and use nuclear fusion energy to supply the antimatter capture device to realize the three functions of antimatter, nuclear fusion, and gravitational energy.

Among them, nuclear fusion and gravitational energy mainly supply energy for the spacecraft, while antimatter will be directly sent to the power system.

This is the most suitable solution at present. Gravity will greatly reduce the loss of energy in other aspects, and even the spacecraft itself does not need to consume a lot of energy to maintain gravity.

The disadvantage is that the planetary battleship will lose detection accuracy, for example, the detection of gravitational waves will be completed with the help of other secondary ships.

In order to make the planet smaller in size and large enough in mass, the Federation specially selected the core of the star.

After a star is destroyed, it is actually only very unlikely to form a red dwarf, especially a low-mass star. In most cases, the star will die directly, and the dead star will leave a solid core. The density of these solid cores may exceed 20g/cm^3, which is greater than the density of gold.

Some star cores may be only about the size of the earth, or even smaller than the earth.

Most of these star cores come from red dwarfs.

The question is, where to find star cores?

In fact, there is no need to find them. When the Federation wanted energy before, it destroyed a large number of stars. Now the Federation can freely choose suitable star cores.

Because it is the first planetary battleship, the Federation also compressed the manufacturing cost as much as possible, using this planetary battleship as a practice, and the Kunlun was the same at the time.

But because it has a star core, the size of this giant ship is not small after all.

The overall shape of this giant ship is elliptical, not as elliptical as a rugby ball, but more like a more round egg.

On the horizontal axis, the length of the spacecraft reached 24,100 kilometers, the overall height and width are the same, 20,200 kilometers, the inner core diameter is 15,700 kilometers (the diameter of the earth is 12,742 km), and the mass of the core is about 7.66 times that of the earth.

The overall mass of the spacecraft also reached 7.125 kg, which is 12.05 times the mass of the earth.

About 40,000 years after the birth of the first dwarf planetary giant Kunlun, finally, the first planetary giant "Kunpeng" of the Federation was born.

Using the most advanced giant antimatter propeller of the Federation with a diameter of 7,125 km, its speed can also be stabilized at 34,217 km/s.

It is not an exaggeration to say that it is a milestone.

But it does not feel much improvement, because the speed of Kunlun was 24,858 km/s at the beginning, and the speed difference between the two was only 37.6%, which means that in fact, the propeller technology of the Federation has not changed revolutionaryly in 40,000 years.

The Federation achieved many firsts on Kunpeng.

The first planetary giant ship was built.

For the first time, a real planet was stuffed into a giant ship.

For the first time, a mechanical god was installed on a warship.

For the first time, a complete ecosystem was realized inside a warship.

For the first time, a super-giant single thruster was made.

For the first time, a long-range weapon was carried on a warship.

For the first time, a Lagrangian orbit system was built for a warship.

For the first time, a dwarf planet-class material extraction device was installed inside a warship, and dwarf planets could be sent into the device to be converted into energy.

…

Countless firsts.

Of course, Kunpeng also has its own firsts.

Its first time was to reach the end of the cosmic Silk Road and go to the real battlefield.

Thanks to the breakthrough of P=NP technology, Kunpeng is also the only warship that is completely controlled by the host machine. There is no living thing inside it. As for the first time to realize a complete ecosystem in a warship, it was a huge undertaking. experiment.

Since there is a planet in the planet-class giant ship, it is feasible to build a complete ecological chain on the surface of this planet, and the experimental results are indeed true.

But then its internal ecosystem was destroyed, because maintaining this ecosystem requires a certain amount of energy.

The Kunpeng can theoretically be broken down into small parts and then transported through a super hedging device, but in reality this is not possible.

Because of the existence of the core, battleships can be split apart, but planets cannot.

Therefore, the Kunpeng can only fly to the end of the Silk Road of the Universe by itself.

"The planet-class giant ship will shine on the battlefield." Ella said towards Yan Xia, who seemed to have absolute confidence in the Kunpeng.

"The computing power of the Mechanical God installed on the Kunpeng has surpassed that of me who did not have P=NP technology before. In theory, it is not a battleship at all, but a fortress."

Ella changed the naming method of battleships, and the planet-class battleships were officially named Star War Fortress.

Because it is too big and can accommodate too many things, in fact, Kunpeng does not need to carry any battleship units at all, because it can produce battleship units on its own, and it will continue to produce battleships along the way. When it reaches Olive Branch When it is within the civilization star domain, it will develop into a huge fleet.
