Tower Defense Strategy

The particle weapons provided by the alien octopus to country C should be called particle stream weapons to be precise.

With one more word, the level of science and technology represented is completely different.

By asking the NPCs in the game, we can see that the particle stream weapon is a kind of equipment that was popular nearly two thousand years ago in the background of the game, which is similar to the age of the 16-fold sodium battery that has been mass-produced.

Compared with the earth ball before it was disturbed by alien knowledge, it has a span of about 300 to 500 years, and it also needs to use materials that can only be produced in space.

The jet velocity of the particle flow weapon is about 10,000 kilometers per second. In contrast, the high-pressure water gun used in the industry for cutting steel plates has a jet velocity of only 1,500 meters per second, and atomization will occur a few centimeters away and lose its cutting ability.

To accelerate particles to this speed, there are two key devices: melting furnace and acceleration track.

Both devices encountered difficulties.

Melting furnace is a device used to melt salt (not table salt). Depending on the type of salt and the difference in design purpose, the temperature ranges from two hundred degrees to three thousand degrees.

In theory, the higher the temperature of the melting furnace, the better, but as a mobile weapon, at such a high temperature, it can only be used in a fixed manner like early artillery in battle, otherwise the waste heat that cannot be processed will cause major problems for the entire vehicle and aircraft.

The surface is not like in space, just a few sets of things that can be thrown into it at any cost.

…However, the waste heat problem is still a relatively late bottleneck, and it is relatively difficult to solve.

One problem is the fluidity of the melting chamber.

Many salts undergo melting and then cool down to produce other substances, and they are all accompanied by crystallization. The crystals may "grow" on the metal, making it difficult to completely remove them by reheating.

After many rounds of material screening and experimentation, I finally chose the carbonate that will produce carbon deposits...it seems correct to say that it is a stone, but the public information shows that it is not calcium carbonate.

In the end, the waste heat problem had to surrender to the cost and the total weight of the system, and insulation ceramics were selected.

The thermal conductivity of the ceramic itself is very poor. The thermal conductivity of the thermal insulation ceramic developed by the directional research and development is very low. After the melting chamber is completely wrapped, the temperature difference of thousands of degrees can only transfer a few joules of heat per second, which is more conducive to maintaining the external temperature.

During the period, the project team also considered using the Black Magic Conductor series of superconductors, but the starting temperature of that thing must be several hundred degrees. If it is directly heated by electric current, the energy consumption is too large.

Another worry is for the soldiers to consider. If you really want to use this weapon, I am afraid that you have no intention of considering too many panel values. The black magic guide's superconducting temperature range is too small, and any carelessness may cause superconducting lines. Melt down.

On the White Magic's side, although the temperature difference between the jet and the superconductor caused difficulties in heat radiation and space-time heat transfer, it was much less difficult to overcome.

Air is a poor conductor of heat. The temperature rises very slowly. As soon as the acceleration track opens, the cold air particles are accelerated and pushed out. During this period, as long as the heat radiation brought by the jet is controlled, the pressure of the cooling system is limited.

The difficulties on the acceleration track are even more peculiar, and it is the first time that the entire scientific research system has encountered such a strange bottleneck.

Insulation film thickness.

Weaponization of particles requires huge energy to be given to particles in a short distance. If you follow the superconducting wires of a few millimeters thick like the electromagnetic orbit launcher outside, you will not be able to reach the specified speed.

The superconducting wire must be thinner and thinner.

The halfway project team also set up two teams of 30 people to improve the equipment for the manufacturer and successfully made 15-micron cores.

How thin is this thread?

The diameter of a child's hair is between 30 and 40 microns, which means that a small three-core cable can be made from a child's hair, and there is plenty of space.

Before this ultra-fine wire core was released, the diameter of the thinnest wire core mass-produced in Country C was 40 to 50 microns. It is easy to break when it is made thin, and there is no corresponding demand.

However, the insulating varnish is pulled when the core that can maintain continuous processing is made.

With the existing spray paint technology, the sprayed paint surface must be at least 40 microns in order to achieve no pores.

The enameled wire is a baking varnish, and the solidification and shrinkage will make the thickness a little better, but it is not much better. The current transmitted by the superconducting wire is not tens of hundreds of amperes, and the insulation is just needed.

As a result, we coordinated the support of all parties for this project. It took half a year to get an enameled wire with a final diameter of less than 35 microns. If you look at it enlarged, the proportion of the insulation layer is similar to that of ordinary plastic sheathed wires.

It is still thick, but in order to ensure the insulation performance, there is no way to make it thin.

The big cows are still changing the craftsmanship. As a result, there is an order on the paper that requires at least a small batch of equipment before the end of the year, and problems will be solved later.

There is no other way but to go hard.

The accelerator gives three lines to advance together.

One is a single-wire coil; the other is a collection of coils similar to an orbital transmitter, that is, the outside of the acceleration ring is arranged with complete coils similar to transformer coils; the last line is a stranded wire.

Among them, the twisted wire is also made by using the newly improved process, which is twisted with six wires and painted to form a twisted wire with a final diameter of 80 microns. The advantage is that the strength is large, and a larger current can be passed before the superconductor is activated. When the jet is accelerated, the heat at each node is more balanced.

Without too many accidents, the twisted wire finally won.

The reliability of the single-wire coil is too poor, the outdoor test field will be burnt, and even the core of the wire will be broken during the winding process. The technology is too immature, and it is not necessary to hit it on a vehicle such as a tank.

The complexity of the coil assembly is still too high compared to the vehicle weapon. With the addition of cooling requirements, the weight and cost of the entire system are a bit higher.

After forcibly breaking through the barrier, the situation mentioned above appeared, and the range was not enough.

The project team made an experimental gun based on the weight of the currently equipped electromagnetic tank. As a result, there was no lethality at three kilometers outside.

But it must be emphasized that it is worthy of being an alien weapon. The destructive power of this thing within 500 meters is amazing. It directly burned a hole in a homogeneous steel ingot of one meter thick.

It seems a bit weak to penetrate a meter of homogeneous armor. After all, the armor-piercing shells of tank guns can hit 1500 mm. The problem is loss.

The particle flow weapon consumes only 100 grams of carbonate in one shot, and a 120mm armor-piercing projectile, even with a little less charge, will have to start with 15 kilograms.

This means that a tank platform that uses particle flow weapons can have almost unlimited ammunition in a single battle as long as it can connect to the urban power grid.

Unfortunately, no matter how strong it is, it can't cover up its current shortcoming of insufficient attack range.

There is no good way to discuss the project team, and the weight of the whole gun must be increased.

The above is also unambiguous, the chapter is one cover, designed according to the weight of the artillery system and power system of the 155mm self-propelled gun.

At present, the output of octoploid and hexaploid sodium batteries has been increased, and a small number of all-electric electromagnetic tanks are also installed. The weight of the power system naturally includes additional weight such as fuel.

In addition, the weight of the self-propelled gun is not only the difference in gun weight caused by the caliber, but also the loading system and the weight of the ammunition. For this thing, a shell is 35 kilograms upwards, and the ammunition compartment is calculated by ton.

Converting them all at once, the weight, space, and energy are much more generous. The project team cannot solve the problem of high-energy particles being ruined by the atmosphere in the short term. It can only pile up electricity to increase the particle flux.

The time was approaching August, and the country J in the east was almost overthrown by a monster. The project team finally came up with a cannon that is eight kilometers away that is lethal to the second-level monster, which is still an experimental version.

Looking at the results, the officers frowned and were obviously unsatisfied. The vehicle has not been finalized, but because of the tight time, he still signed the order and moved directly to the procurement stage.

Next, dozens of companies will work together to design and produce all-electric new self-propelled guns. It took only two and a half months for the first vehicle to roll off the assembly line, and two hundred vehicles were required to be delivered by the end of the year, meaning that the monthly output in the last month would reach 120. Get up and down!

For the safety of people, keep working overtime.
