Tower Defense Strategy - Chapter 307

A few days after Feng’s assembly machine started the production authorization process, a new helicopter was tested at an air force base in country C.

Thunder, taking the meaning of thunder father and electric mother, taking into account factors such as equal rights people, it is difficult to directly use thunder father and electric mother, and simply uses a very widespread name.

Raiden Helicopter is an all-electric helicopter based on hexadecimal sodium battery and new super capacitor!

The super capacitor used in it is a high-energy capacitor that was inspired by the extraterrestrial knowledge gained in the game in the process of researching sodium batteries.

Supercapacitors are not a new concept. During the development of electric vehicles, they have been proposed many times, and some manufacturers have even made capacitive concept cars.

The energy density of the hexadecimal sodium battery, the latest version of the test average value is 11 megajoules per kilogram, less than a quarter of gasoline.

This kind of energy density is not a big problem on tanks and vehicles, but the requirements of flying objects for energy density are almost harsh, and the sixteen times body barely supports the basic flight requirements, and it is necessary to use high-energy capacitors.

The new type of capacitor used by the Raiden helicopter has an energy density of 130 megajoules per kilogram. Like all capacitor components, its stored energy will quickly be lost.

There is no way to compare with the dozens of hours of decay cycle of magnetic capacitors in the game. After the new type of capacitor is fully charged, the power will naturally decay to one-tenth in about an hour. You can touch it directly with your hands four hours after the battery line is disconnected. .

Utilizing the hybrid energy source of hexadecimal sodium batteries and supercapacitors, plus the weight advantage of the fly-by-wire system compared with the fuel system, the lightning is inherently suitable for transportation compared to conventional helicopters.

When designing, more or less affected by the monster era, cost is no longer the first priority, whether it can be produced, and the adaptability to future needs and future maintenance capabilities are the key points.

In order to match the concept put forward by the “Prospect for Survival of Mankind in the Post-Disaster Era”, Raiden finally completely abandoned the existing helicopter framework.

By the way, the “survival outlook” is an internal reference report released by the C system at the end of the previous year. Based on the impact of the development of the monster crisis on the industrial chain, a series of concepts for the future surface living environment are proposed. It can be said that in addition to the emphasis on space projects, the entire XX24 global layout of country C was developed around this report.

Back to Raiden.

Raiden did not use the rotor structure of Rotten Street, but used a two-plus-two ducted fan.

Ducted fan means to install the fan in the duct. Compared with the open propeller structure that originated more than a hundred years ago, this structure has better stability and maneuverability, and it is more energy-efficient to obtain the same thrust. However, the requirements for fan materials, structure, and processing are much higher.

Two plus two, the front two refers to the main power fans on both sides of the lightning main structure connected by the beam structure; the latter two refers to the two full-angle adjustable and reversible fan steering at the rear of the lightning Of two auxiliary fans.

Using this two-plus-two ducted fan structure, Raiden has obtained some features similar to a tiltrotor, but the two focuses are different.

The tilt-rotor aircraft emphasizes the horizontal flight speed after vertical take-off. When the tilt-rotor turns to the front, it can obtain the speed of an ordinary propeller aircraft, which is more than 600 kilometers per hour.

Raiden is to meet the conventional transportation needs of various places under the environment of lack of ground transportation capacity in the post-disaster era. The emphasis is on load, so sacrifices are made in the fan angle.

Utilizing the characteristics of drones and all-electricity, the overall mass density of the equipment area has been increased as much as possible. The main body of the normal aircraft is cut horizontally to the remaining one-third, which is its main body, but because it is large, the visual proportions It is narrower than the general UAV body. This design reduces the wind resistance to a certain extent, but the final maximum speed can only reach 320 kilometers per hour, which is similar to the armed helicopters produced in previous years. Of course, it is fast when placed in a transport helicopter.

As an unmanned aerial vehicle, Raiden is also the drone with the largest width (corresponding to the wingspan of a conventional aircraft), weight, and load to this day.

The width of the thunderbolt is 24 meters, the length is 22 meters, the maximum take-off weight is 25 tons, and the maximum load is 30 tons at the standard self-weight.

With a 25-ton helicopter and a 30-ton load, this ratio is not good. A sharp eye will notice that it has a “standard self-weight” description.

An unmanned aerial vehicle, all-electric, where does the change in its own weight come from?

The answer is the increase or decrease of power supply modules.

Learning the advanced experience of aliens, combined with local technology, the lightning has six tons of weight from the power modules that can be added or removed. After removing them, its load will naturally increase to 36 tons, but at the same time The full-load sailing distance will be shortened to within 180 kilometers.

There is also an additional power module interface, which can add up to five tons of electrical load.

It’s not impossible to continue to stack batteries, but if the distance is too far, the traditional large transport aircraft has more advantages, so there is no need to burden the helicopter with too many additional tasks. Its main working range is transportation within 500 kilometers.

In order to meet some special needs, when the Raiden test flight, there is also a large sister aircraft being assembled.

Its sister machine is called Costin.

The name Costin is derived from a bird of prey, the Falconiformes, which are customarily called eagles, but the Falconiformes are not as big as eagles. Using this name also means that Costinus can lift relatively heavy prey.

Costin is larger than Thunderbolt, with a length of 28 meters, about the same as a heavy fighter, with a wingspan of 32 meters, which is close to the wingspan of a medium-sized fixed-wing transport aircraft.

Regardless of being just such a lap, Costin, in order to reduce weight while ensuring sufficient strength and obtain a better load ratio, the proportion of titanium alloy used is twice as high as that of lightning, and carbon fiber is used as much as possible in the skin. Woven material.

As a result of the cost, Costin’s actual aircraft weighs 30 tons, but it can lift 56 tons of heavy objects and reach a flying height of 2,200 meters at the same time. If the flying height is lowered, the cargo can be heavier. .

The 56-ton figure is wonderful. It happens to be the latest improved version of the all-electric electromagnetic tank plus the full weight of the crew, or the particle flow self-propelled gun that was put into production in the last few months of last year, plus two 200-kilowatt generators. the weight of.

After more than two years of extraterrestrial knowledge, it’s not that you can’t make airplanes with heavier loads, but after all, these things serve the post-disaster era, and the design has to take into account the supply conditions of parts in the post-disaster era. Titanium alloy is originally a very difficult material to process, and the equipment requirements are very strict. It will be very difficult to produce after the disaster, and it is impossible to make it particularly large.

Costin’s load capacity is a small change in the design process. It itself is not designed for heavy equipment airborne. It is more for the first-level rocket recovery system. It was just designed to be compatible with electromagnetic tank transportation. , Just fine-tuned a bit.

The first-level rocket recovery of electromagnetic rockets mainly relies on large military transport aircraft, but transport aircraft are not all-powerful.

The large transport aircraft used in country C in the previous years was deliberately designed to be relatively fat and can be packed with a thicker load, but the length is very problematic.

If the first-stage rocket is forced to fall back to the grassland, the lengthening of the first-stage rocket is an unavoidable trend. Fortunately, the 3.35-meter caliber will inevitably exceed the transport capacity of the transport aircraft. Either it becomes a detachable two-stage fuel tank, or it needs an air transportation force that is not restricted by the transportation shape. Costin is that supplement.

The problem of the two-end fuel tank is also being solved. The oxidizer tank and the fuel tank are originally two different things, but they have to be separated from the rocket shell, which involves strength and pipe connection issues. After the modification, the original launch purpose must be maintained. It will inevitably lead to an increase in weight.

It’s always okay to make more preparations, otherwise it won’t be good for a single item to go wrong.

On the other side of the planet, country A is also mobilizing forces to do great things.

Country A once implemented a strategy. Dameizhou is a great continent for local people. The subtext is that the affairs of Dameizhou are all inclusive. People from other continents take care of their own hands.

Based on this strategic orientation, country A has great influence in the entire beautiful continent. Most countries have agents directly funded and trained by country A, and most of them are compradors with the nature of two devils.

The existence of the agent enables the entire Dameizhou Continent to cooperate well with the industrial chain of Country A.

Or they can’t be regarded as cooperation, they are just providing raw materials and the market.

In the last century, all countries in the southern beautiful continent that intend to develop industries have suffered economic blows, such as the narrowest and narrowest country in the world.

This strip with a width of less than two hundred kilometers from east to west and a length of more than 4,000 kilometers from north to south was attempted to turn red 50 years ago and then was severely beaten.

First, restrict the export of mining parts and components; second, restrict the sale of grain from the entire continent to the place at normal prices; after the first two items have dried up the counterparty’s foreign exchange, through its own influence, it is mandatory for any organization not to provide loans for it ; Finally, find the right opposition and provide the resources needed for the rebellion.

The successful beating directly led to the death of the country’s leader at the time. He was not the first to be killed by country A’s despicable means, and it is impossible to be the last.

To be more objective, as a relatively large country in the beautiful continent of South Africa, the failure of the strip country cannot be ruled out that its own governance capabilities are immature. It is certain policy reasons that have caused its domestic food production enthusiasm to plummet, resulting in a continuous reduction in grain production. , So that country A can push the inflation rate to fly at a small price, and it took just three years.

But as an example, similar things are common in the entire beautiful continent, and there are people who directly arrested the chief of the family and sentenced them to more than 100 years of imprisonment.

Understanding the influence of Country A in the Great Continent in the past, we can see that the integration process of the Great Continent implemented by Country A today still has a certain progressive significance.

In the process of integration of the Great Continent, Country A took the initiative to support some local industries.

Of course it’s not that some people suddenly become more enlightened, it’s purely based on interests.

In the past model, country A searched for the wealth of the beautiful continent, with a layer of compradors in between. For example, country A once hoped that a certain country would plant less “grass”, thinking that the focus is education, but under the comprador system, the money would not be put on the ground, and in the absence of industry, education alone would not make others give up planting “grass”. “This way of getting rich.

Now, after the destruction of monsters led to the collapse of the original system, Country A has gone straight away. It no longer needs an overly corrupt middleman, which is conducive to its industrial adjustment in the entire beautiful continent.

Ocean shipping is becoming more and more dangerous today. It is difficult for country A to expect all products to be exported to the world islands, and it is also difficult for large-scale import of raw materials through the mid-ocean and western oceans. It is indispensable to realize the internal circulation in the beautiful continent. But the people here are too poor. During normal times, they can only grow “grass” and sell them to country A. They are blown out by monsters, and the area for growing “grass” has shrunk several times. Some areas are already poor enough to be bananas. Can’t afford it!

Therefore, in order to achieve internal digestion, country A has to relax some of the long-arm jurisdiction laws and allow businessmen to support some industrial projects in the southern beautiful continent. Of course, these projects cannot compete with country A for high-end excess profits.

In addition, ~www.mtlnovel.com~ the country’s reorganization of the military forces on the southern continent.

Except for the adjustment of the location of military bases, this round of reorganization was mainly affected by the failure of several large-scale war projects in the previous decades, and the original two-devil system was no longer pursued.

According to the new bill that came into effect only two months ago in country A, the troops in all regions are mainly locals, using media to ensure their enthusiasm in defending their homeland, followed by the synchronization of military data links. The supporting strike force exists…that is, it is only responsible for dropping nuclear bombs.

There is a cognitive difference here.

Country A has never paid much attention to human life. If it insists on paying attention to it, it is only a by-product of serving the rich. It shows that Country A uses the world’s largest medical market, and its average life expectancy is only one-tenth of that of other countries. The investment is almost the same. Most of the time, human life is just a quantifiable consumable. It’s your own food if you can’t survive the harsh environment. Anyway, if you lack it, you can introduce immigrants. There are so many people around the world.

The construction of the Southern Great Continent also follows the underlying logic. It does not seek to keep everyone in the beginning. Through construction investment, it is enough to ensure that the market size does not continue to shrink due to the shrinking population caused by monster attacks.
