How the Zergs were Made

Chapter 130 Railgun

The railgun uses electromagnetic force to propel shells, a kinetic energy weapon with huge lethality. Before Hogu crossed over, this thing was a new concept of sci-fi weapons, and only appeared in those sci-fi film and television works and novels.

Unlike traditional cannons that use violent chemical reactions to provide propulsion, railguns themselves do not need to consider the powerful shock waves and reaction smoke generated by chemical explosions.

Whenever traditional artillery wants to increase the power of the artillery, it is necessary to lengthen the gun body to stabilize the ballistic, and the charge of the shell needs to be larger to provide a more powerful driving force for the shell.

All in all, the volume needs to be bigger and bigger.

It's fine if it's just like this, but once it's put together with another law of physics, the problem will become very serious.

The strength of the object will become weaker with the enlargement of the shape. The fundamental reason is that the strength provided by the atomic bond can only barely compete due to the increase of internal stress. Once the external force amplifies the stress, it exceeds the atomic bond itself. The power that can be provided, then this object will also declare disintegration.

Therefore, the artillery barrel needs to be thickened, because it needs to resist the shock wave generated by the explosion of the shell charge.

But the railgun does not need to consider this kind of problem, so when Hogu was still on the earth, this type of cannon was generally favored by all countries.

The only problem that shackles countries from popularizing this kind of cannon to the military is energy, which consumes too much electrical energy. The essence of railguns is to convert electrical energy into kinetic energy that drives shells.

On a chaotic battlefield full of artillery fire, a cannon still connected to the rear nuclear power plant is undoubtedly a bad idea. The mobility alone is enough to make the military general turn around and leave.

But Hogu doesn't need to think about this.

Energy Supply? Every corner of the earth's surface, including the seabed, is using chemical energy to generate electricity. There is a power station on the surface of the entire planet to power the railgun. The low-temperature superconductor realized by dry ice is built in the rhizome, and there is no loss and the global coverage of the electrified wire That's it.

It is precisely for the purpose of building these that Huogu perfunctorily completed the projecting design of the sky eye into space, directly applying the design layout of the earth rocket.

When the planet's rotation turned the railgun's muzzle direction to the alien fleet, Hogu's order came.

emission!

After the command was issued, the fist-sized metal body began to speed up under the action of the electric field.

Because it has to fight against the gravity of the planet itself, the speed of the metal body can only increase by one meter per second for every meter it travels, and the air resistance is negligible. All the air in the gun is sucked away, and it is in a vacuum state. The muzzle has penetrated into the fugitive layer, so there is no need to worry too much about the air entering from top to bottom.

The length of the rail gun has reached a length of 1000km. This kind of monster-like material science has never been mastered by humans on earth.

This is the accumulation of Huogu since he traveled for such a long time, and it is also the reason why Huogu didn't ask them to study chemistry in the first place.

The essence of chemistry is the atomic bond structure that connects atoms to each other. The entire macroscopic world is built by losing and gaining electrons. More essentially, it is the 'electromagnetic force', one of the four forces on the microscopic scale.

With this understanding, Huo Gu has been trying various types of atomic combinations since the Hadean Eon, basically combining all the atoms that can be obtained on the planet.

Huogu's understanding of chemistry is as difficult as a child's understanding of assembling building blocks, let alone such a long-term accumulation.

According to the conversion, the length of the railgun barrel is approximately equal to the velocity of the shell itself, that is to say, the initial velocity of the fist-sized shell when it leaves the muzzle is 1000km/s.

What kind of concept is this?

This is one three hundredth of the speed of light, and the accelerated projectile itself has a mass of 10kg, and its kinetic energy has reached 5x10^11 joules. Constraining the energy released by a nuclear bomb to the size of a fist, there are basically no atomic bonds that can Can withstand this level of kinetic energy.

The key point is that there is more than one projectile launched into the universe. Due to the particularity of the railgun itself, there is no need to consider the airtightness of the explosion chamber at all. Similarly, it doesn't matter if the distance between projectiles advancing in orbit is reduced to a decimeter, because of the vacuum environment in the barrel, there is no need to consider the cavitation effect.

There is not only one similar building, so the scene displayed is a terrifying barrage with a speed of 1/300 of the speed of light, and 500 billion fist-sized projectiles are projected out.

However, although these projectiles are powerful, it still takes seventy or eighty hours to hit the target, which gives the alien fleet time to react.

The announcer's hasty report echoed in the bridge.

Commander! The radar echo scan has detected a large number of objects approaching at high speed! The speed is 1000km/s! Launching direction, target star!

Tell the whole ship to change course, form a spread out formation, and widen the distance.

The fleet commander gave the order very calmly, his eyes fixed on the projector, and what appeared on it was a circle of blood-red warning signs approaching his own fleet at high speed.

The time was the fifth hour after Huogu fired those metal barrages. Since the two sides were approaching at high speed, the relative speed was higher and the meeting time was shorter.

Even on the bridge, the aliens could clearly feel a slight tremor. Obviously, the spaceship was shot.

Thirty parts of the vibrating armor are damaged!

Good air tightness!

The engine group is normal!

The life support system is normal!

Four forts are damaged!

...

The report sounded one after another, and the commander's tense expression showed a little relaxation, and he asked immediately.

What about the ships?

Six ships have been confirmed damaged due to too many bullets. Three ships are being repaired due to hitting vector nozzles, which may affect the deceleration of the spaceships behind. The other ships survived because of your previous order to turn on the vibrating armor. Difficult, it’s just that the vibrating armor is damaged.”

The commander nodded slightly and gave the order again.

Instruct the maintenance team as soon as possible to repair the vibrating armor. This kind of attack is absolutely impossible to happen only once, and the ships will maintain their current scattered formation and not change.

yes!

If Huogu knew the result of this attack, he would probably jump in anger, if he had feet.

Although it can't be said that he had high hopes for this wave of attacks and believed that he could win or lose in one go, the results this time were far lower than Huogu's initial expectations.

The existence of the vibrating armor made Hogu's surprise attack come to an end without a problem, and he spent a lot of energy, material resources and energy in exchange for only six ships out of ten thousand battleships.

PS: Sorry for posting so late, I have to write a paper recently, sometimes the update may be late, so please be considerate, it will not be the end of next week, if there is still, um, it must be Cavin’s fault OwO
