It took more than half a month for Tianming to finally build this maritime city.

Cables, optical cables, water pipes, various lighting, ventilation, motors and other equipment and facilities used in the interior of the maritime city are still being installed, and more than 10,000 workers will have to work for at least a month to complete the installation of these facilities.

After Tianming brought all the personnel and equipment over, the sea city basically didn't care much, and he began to be busy building a new type of aerospace aircraft carrier.

The new aerospace aircraft carrier is still made of silver and steel shells, but the shape and internal structure have undergone earth-shaking changes.

Instead of using a turbine blade engine as a lift boost system, it uses four three-hole tandem plasma engines as a lift system.

Generally speaking, in terms of power and efficiency, the engine generally starts with the lowest end of the chemical fuel-burning engine, then the plasma engine that uses nuclear energy, and finally the most efficient is the legendary photonic engine.

Photon engine is also called antimatter engine, when the positive and negative substances collide, an annihilation reaction will occur, and a large amount of energy will be released, this energy is light energy, the light emitted, just like the gas is ejected from the rocket vent, will also produce a reaction force, if the light is strong, this thrust is very large.

There's a problem with that.

Can a spacecraft fly faster than light?

Someone has specially calculated that if nuclear fusion is used as an energy source, even if the energy generated by the fusion of matter is all converted into the thrust of the spacecraft, it is found that even if 99% of the material on the entire spacecraft is fuel, the speed of the spacecraft can only reach 80% of the speed of light.

In other words, no matter what kind of nuclear energy is used, even under the best conditions, a spacecraft can only reach 80% of its speed.

Antimatter engines can convert matter into energy in its entirety. Let the spacecraft fly faster than the speed of light, but according to Einstein's theory of relativity: in the three-dimensional universe, the faster the object, its length will be stretched, its mass will begin to increase, and finally it will encounter a barrier - the barrier that cannot break through the speed of light.

Scientists have also proved through physical practice that no particle can accelerate to the speed of light, no matter how much energy the particle accelerator provides.

Matter cannot break the speed of light.

In science fiction, there are four hypothetical ways to achieve faster-than-light flight.

1。 Jump, through guò folded space to achieve faster than the speed of light.

2. Curvature flight, distorting space, allowing the spacecraft to achieve a similar "downhill" effect of flying, the famous series of movies "Star Trek", is to achieve superluminal speed in this way.

3. Space stripping, stripping out the space in front of the spaceship. Drive space itself for high-speed flight, bypassing the insurmountable law of the speed of light.

4. Hyperspace, assumed to be outside of three-dimensional space. There is a hyperspace in which the minimum speed is the speed of light.

That is, unless humanity acquires the technology to influence space. Otherwise, it is impossible to achieve faster-than-light flight by simply carrying out energy conversion.

Tianming doesn't need to care about whether he can achieve superlight speed, he just needs to build the plasma engine that this aerospace aircraft carrier will use.

……

After five days of study. Based on the experience of manufacturing plasma engines for aerospace aircraft last time, Tianming quickly manufactured a new type of high-power plasma engine.

……

The role of superconducting materials is enormous.

The electromagnetic cannon and electromagnetic ejection system to be installed on the aerospace aircraft carrier require a lot of superconducting materials.

Superconducting materials have no resistance and are 0.

The reason for the formation of resistance is that the electrons hit the atoms during the movement.

The reason why the resistance of superconducting materials is zero is that there are no gaps between the internal molecules of this material, and electrons can pass through the edge channels without hindrance, realizing the lossless transmission of current.

Superconducting materials at room temperature have gaps between molecules, and the superconducting effect can only be achieved after the molecules inside the conductor no longer move in a low temperature environment and the "gap" is closed.

And to close the "gap" of atoms (molecules), it can only be achieved at least at a low temperature of minus 1 or 200 degrees, and at room temperature, almost no such matter has superconducting ability.

Using the principle of "closing the gap", a long time ago, Tianming synthesized a new material, the molecules inside this material are fixed, and there is no gap at room temperature.

This material was named "Superconductivity 1".

The electromagnetic cannon introduced earlier was made by Tianming from this material, and the electromagnetic cannon Tianming also planned to be slightly modified and installed on the new aerospace aircraft carrier to become its iconic and important weapon.

Recently, Tianming has produced tens of thousands of tons of "Superconducting No. 1" materials, some of which are made into permanent magnet blocks, and some are made into cables and wires -- which will completely replace the conventional copper and aluminum wires and be used in the new aerospace aircraft carrier, making it an aircraft carrier with a fully superconducting power system.

……

The second is the energy system, the new aerospace aircraft carrier still uses nuclear energy, fission nuclear energy, but it is somewhat different from the previous nuclear power generation ship.

It uses plasma to generate electricity.

After any substance is heated to a high temperature state, it will be in a special molten state, if the temperature continues to rise, the molecular bonds are broken, and the substance will either decompose into an elemental state or ionize into anions and cations, at this time, plasma discharge can be carried out.

The melting point of black steel is 8200 degrees, and when most substances become molten or ionized, the temperature is enough as long as there is a temperature of 3,4000 degrees.

At this time, the advantages of black steel are reflected, with a melting point of more than 8,200 degrees, the temperature of the nuclear reactor can be maintained at 5,6000 degrees for a long time, and the core will not melt. In a general nuclear reactor, as long as the core temperature exceeds 3,000 degrees, it is extremely dangerous, because as long as the temperature rises a little more, if it is not cooled in time, no matter how strong and thick the shell is, it will melt, and then there will be an explosion and nuclear leakage, which will cause endless harm.

A temperature of 1,2000 degrees Celsius is not enough to heat the substance to the plasma state, so most nuclear power plants use steam turbines to generate electricity. Even the very small nuclear reactor on the nuclear submarine uses high-temperature steam to generate electricity, and the efficiency is not very high.

Under the guidance of several experts, using black steel materials, Tianming soon built a nuclear power plant with plasma power.

The entire nuclear power plant consists of three parts: a core reactor, a plasma discharge device and an external cooling system.

When the core reactor is working, it can produce a high temperature of nearly 6,000 degrees Celsius, which ionizes the electrolyte. Two ions, anion and ion, are generated, and under the guidance of the superconducting electromagnetic coil, they begin to discharge externally and generate an electric current.

Because the core reactor temperature is too high. Cooling had to take place, so the cooling system outside the reactor was filled with a lot of fresh water, which in turn would drive the steam turbines. Generate a lot of power generation...... In other words, this kind of nuclear reactor looks like a normal reactor in appearance. It seems that all of them generate electricity by heating water vapor.

But the power of the power generation is surprising, the same nuclear fuel is used, the combustion rate is about the same, but the nuclear reactor with the addition of ion power generation device is almost double the power generation without this device.

In other words, if the nuclear reactor on the nuclear power generation ship is rated at 500 megawatts, if it is equipped with an ion power generation device, the power generation can be increased to 1,000 megawatts.

Tianming is not very interested in this promotion, no matter how much it is doubled or two, the electricity generated is enough.

Ma Yuchen, who presided over this research and development work, was excited, and said excitedly with Tianming: "Commander, this promotion is great!" If this kind of reactor is installed on an aircraft carrier, it may be installed with two reactors in the past, but now it is only necessary to install one, if it is installed on a nuclear submarine, the previous nuclear submarine may have to replace the nuclear fuel once every 20 years, and now it can be replaced once every 40 years, which is a qualitative improvement! ”

Nowadays, people pay attention to efficiency and cost, and try not to do what can be done for one dollar, but not for two or three dollars.

This is the case with the new type of nuclear reactor, which was previously designed to allow the space carrier to fly, and it was necessary to install about four nuclear reactors with a power generation capacity of 500 megawatts.

In addition to being able to fly, the aerospace aircraft carrier also has electromagnetic cannons and laser weapons on it, which are large power consumers, and the total power of the 4 nuclear reactors of 2000 megawatts is the minimum power to ensure that the aerospace aircraft carrier is in flight and can use some weapons.

The power of the new nuclear reactor is twice as large as expected, so the number of reactors equipped will be changed from four to two, which will save a lot of space and manpower, and the complexity of the aircraft carrier's operation will be reduced a lot.

The other is high-power lasers.

Laser weapons are laser weapons that use the güò electron beam to excite the laser medium, release a special wavelength of light, and then use the reflector surface to repeatedly bounce these rays back in the resonance cavity, and finally gather into a beam, through the guò movable lens to launch the beam to any place it is aimed at, to achieve the effect of destroying the target.

The power of laser weapons is related to power, and the magnitude of power is mainly related to the dielectric material in the laser, the better the material, the more light released, the stronger the energy concentration, and the greater the lethality.

There are many types of solid-state lasers, gas lasers, excimer lasers, dye lasers, carbon dioxide lasers, and so on.

The number of lasers is also related to the attack power of the laser cannon, and the more lasers there are, the more powerful they are. However, considering that the size of the laser cannon cannot be too large, the number of lasers is generally not too large.

Tianming took out a variety of materials for experts to do, and finally found a special sapphire, after being excited by the electron beam, can release an unusually dazzling purple laser, the brightness is very high, can reach 100 billion times that of the sun, which is 5 times that of the giant pulse ruby laser, and the unit power has reached an astonishing 2 megawatts.

2 megawatts, which is almost 20 times more than the average solid-state laser.

Zhu Jingming, an expert in laser weapons, said: "It may be that this sapphire has elements that the earth does not have, and it is very suitable for laser weapons as a laser, a laser cannon, as long as it is equipped with 10 laser generators and a 20 megawatt laser beam, it can easily hit any target within 10 kilometers." ”

"10 km? The range is so short? Tianming frowned a little.

Zhu Jingming patiently explained: "Commander, in the atmosphere, the attack distance of 10 kilometers is quite impressive, because light is only a kind of energy, which is easily affected by matter, and during the launch process, it will be absorbed and scattered by the atmosphere, and the energy decays very quickly. If this laser cannon is used in space, the killing distance can be close to infinity. ”

"But 10 kilometers is still too short, is there a way to increase it? It's best to achieve the effect of 30 kilometers or 50 kilometers. ”

"If you increase the range, you can reduce the lens caliber or increase the number of lasers, and if the total emission power can be 100 megawatts, it is not a big problem to attack targets 50 kilometers away."

"Then raise it to 100 megawatts, how can such an advanced weapon as a laser cannon become an ornament that can only hit targets at close range?"

The sapphire to be used in the laser was found from the bottom of the blue mercury seabed, and it was not easy for Tianming to go to the sea to find it, so according to the internal molecular structure of this sapphire, the sapphire was synthesized in the ability space - this took a little effort, because there is an element in the sapphire that is unique to Blue Mercury, and Tianming has no way to directly create zào, but there is an element in the sea water of Blue Mercury, so he extracted this element from the seawater.

Soon, a bunch of sapphires were produced by him.

Plasma engines, superconducting materials, electromagnetic cannons, nuclear reactors, laser weapons, these difficult things have all been manufactured, and there is naturally no technical difficulty in manufacturing a new aerospace aircraft carrier...... (To be continued......)
