The hot air balloon manning high-altitude experiment was successfully completed, but it was not enough to satisfy the researchers, who wanted a flight attendant platform with a larger payload and the ability to fly higher and farther;

Therefore, after sorting out the existing knowledge theory, a long-distance airship scheme composed of light gas, special skin, concentrated liquid energy pool, and thruster entered their field of vision and ambitiously launched the corresponding exploration.

After physical and mathematical calculations, they believe that such an airship can even rise to an altitude of thousands or tens of thousands of meters, perhaps its flight speed cannot be fast, but after adding some weapon systems just in case and the supply of high-altitude life gases, it should be able to meet many short-term needs;

For example, sending a certain amount of supplies to the north, or setting up a high-altitude science laboratory..... Naturally, Nesta nodded in agreement.

~~~~~~

It's been about two months since the last time I paid attention to the water weapon platform, and when the day advanced to around August of the 54th year of the rune calendar, good news finally came from the docks of the deep-water port.

Nesta was currently cultivating the all-round cells in the meditation room, and suddenly felt the infrasound fluctuations around her, and in the fluctuations, she detected the definite wave frequency related to the 'Grand Councillor';

So he quit meditation and began to cast a sound spell to receive infrasound signals more accurately;

At the same time, the brain also began to automatically translate the signals.....

'Your Excellency, the first gunboat has completed the combination of power and attack, and I hope you will come and inspect it. ’

The same message was repeated over and over again, until Nesta replied, 'Understood, let's go now', and then repeated it four or five times before stopping.

Nesta ended his practice and got up to head to the deep-water harbor to see for himself.

Before he could go out, the 'totemic connector' in the meditation room vibrated as well, and Nesta turned around and picked it up.

One end of the totem contact period is connected to the wall by vines, and the other end is a structure that resembles a telephone microphone in the previous life, with an earpiece on the upper part and a microphone on the bottom, and the relevant totems of vibration-to-speech and voice-to-vibration are integrated inside.

When Nesta picked it up and activated it with a miniature totem engraved on his fingernails, a clear voice came into his ears,

"Your Excellency, the Ship Research Institute, a signal from the Ship Research Institute ....."

Nesta listened to the liaison on the other side before responding,

"Understood, I'm going to go, please help me prepare the special bus, thank you."

Because of the difference in principle, the transmission of the totem to the signal is not as timely as the phone call in the previous life, and after he said this, it took a while, and there was a response in the earpiece.

"Understood, this will inform you to prepare the car."

After thanking him and saying goodbye, Nesta, who had been naked during her previous practice, first picked up the clothes on the hanger that were slightly more decent and at least covered her body before leaving the meditation room.

As he reluctantly controls the commuter cabin to the ground by communicating with a voice that resembles Freya, the moose cart outside the square that goes straight to the deep-water port is ready.

The body of the car is pulled by a moose, and it is not transported on a track, but on the ground by the rotation of wheels;

The wheels are wrapped in a solid, rubber-like structure, and the feeling of running is quite similar to that of a car in the previous life.

The deep-water port is not far from the main part and is connected by well-established and smooth roads, and it takes about fifteen minutes to reach the moose at high speed.

"Your Excellency, we have arrived." The driver in charge of driving reminded him outside.

After Nesta said thank you and got out of the car, the driver asked again,

"Do you need me to wait for you?"

"Then please wait a while."

"Understood."

~~~~~

Entering the research institute and going straight to the harbor, Nesta saw from a distance the research team composed of ship teeth, machine teeth, Freya, and nearly 100 scholars of all kinds, and their eyes were firmly fixed on a strange boat in the middle of the river.

"Your Excellency the Speaker of the Council~"

The first to spot him was Freya, a girl who seemed to have matured a little more than two months, but when she saw Nesta, she showed no restraint in the joy of her character, waving and jumping up to her from afar.

After her movements, the rest of the researchers also turned around and looked over, and were equally ready to come to greet her.

Nesta stopped their movements, and took Freya, who had already pounced, and spun around in place, then put her down and touched her head and said gently,

"The little one who hasn't grown."

"Hmph~"

"Alright, let's go check it out."

Stopping Freya's quibbles, Nesta stepped forward to the research team....

"Your Excellency the Speaker of the Council...."

In the relatively calm voices of the witch doctors and scholars, there are also more than a dozen slightly immature children's voices, they are middle-grade students who belong to the Central School, and most of them are talented and high-waisted elves, who should be the trainees of the Engine Research Organizing Committee who came to visit or intern today.

"Haha~ Hello, hello little guys."

Nesta looked very happy to see the little ones, and he nodded to the young ones and touched their heads one by one, before coming to the two leaders and looking at the ship on the river as well.

The ship is not as large as expected, and in addition to the overall appearance of a 'ship', it is an enlarged surface version of the 'Armorbreaker 1' self-propelled vehicle.

From a distance, a smoke-emitting chimney was lowered to the tail, and at the front was a semi-submersible reactor chamber with a thick muzzle, which appeared to be a 55 times the diameter of a 560mm or 520mm gun;

The ship is only about 50 meters long, but at its widest point it is 20 meters, and the draft is about several meters deep, making it look like an ugly fat dumpling.

"Introductory?" After a few quick glances, he said to the two witch doctors next to him.

First, there was the response of the ship's tooth (Furnesta), who said,

"As you can see, the attack system is a 55L520mm main gun, and we changed the reaction chamber into a narrow oval, and semi-shallow transverse placement on the deck, but while the vertical diameter was compressed to 7 meters and the transverse diameter was compressed to 13 meters, the front and rear diameters exceeded 20 meters, occupying almost half of the deck space, and because of the deformation of the structure, the compression efficiency was reduced a lot, and the firing efficiency was 27 lamps per round."

After that, it is the addition of mechanical teeth (Masista),

"A charcoal high-pressure boiler and a reinflating steam engine, the former arranged at the rear of the hull and the latter horizontally placed in the lower space of the reactor chamber, can provide forward momentum of about 12 km per lamp and about 3 km per lamp when retracting."

Nesta nodded noncommittally and continued to listen to their explanation,

"Uh... The hull is too light, the interior space is too closed, the bottom needs to be placed with high-density ballast metal, and the charcoal, boiler water, and additional transport ships must be used to replenish it..."

"Shells can be stored on their own with limited space .... Anyway, the rate of fire is so slow, and there is no need to reserve much, but the energy required for the operation of the reactor chamber during launch, and the energy required for the hull reinforcement totem, must be drawn by extending the root system to a special 'energy ship'..."

"The good news is that as long as you don't use plants for mechanical movement like a self-propelled chariot, you only need to activate and maintain the totem with a 'low-energy concentrate' that doesn't add Cave Wolf Cell Liquid."

"Well, it's a little....", Ship's teeth scratched their heads, embarrassed, wondering how to describe it.

"A bit of a waste?" Nesta added accurately.

"Uh... You're right. ”

"Don't let them fool you! These two villains don't have a good heart!! Freya grabbed Nesta's arm from the side and said angrily.

"Hehe~" Nesta smiled and touched her head, although her eyes were still staring at the broken ship on the river, but her mouth asked,

"Okay, don't play this trick of suppressing first and then raising it, come up with your real follow-up plan, and I'll approve it if it's appropriate."

"Little traitor~" Hearing this, the ship's teeth were no longer rubbing, and after glaring at Freya in a pretended manner, he first cast a spell to create a large table in front of him, and then took out a drawing with several folded layers from his arms, spread it out and displayed it.

"Your Excellency the Speaker, look at this~"

His voice was a little excited, and his eyes lit up as he stared at the ship-shaped object composed of complex lines and data marks on the drawing,

"This! This is the big ship of the future! ”

"Tut, why didn't you take it out earlier?"

"Uh.... It's just that when building the first ship, it will take more man-hours, and it will require the cooperation of many witch doctors.... Take out the broken one first, so that you can have a comparison in your heart..."

"Slippery guy...."

Knowing his calculations, Nesta looked down at the drawings on the eucalyptus.....

I have to say that the boat tooth is indeed a big project, and the guy who is now floating on the river seems to have a gap like an axe and a pistol compared to the idea in the drawings.

What leaps on the surface of the paper is a truly huge ship that is more than 300 meters long, more than 55 meters wide, and 30 meters deep.....

'Good fellow, I'm not afraid of a span that is too big and bend my waist...' Nesta, who smacked his tongue secretly, carefully looked at the structure on the drawings and the more important marks under the expectant gaze of the ship's teeth and the rest of the researchers.

Unlike the battleships in his previous life that needed to distinguish between hull and armor, the hull and armor of this semi-magical plant giant ship on the drawing are integrated with the inside and the outside, and they are all plant materials engraved with three-dimensional totems;

Combined with the lightness of the plant material itself, the conclusion of the calculation is....

"Your Excellency, the Chief, with its own size, the empty weight of the hull without weapons and power systems will be reduced to a mere 35,000 tons;"

"With this hull shape, and this little weight, what a terrifying usable tonnage will we get?"

"Don't be emotional, be specific."

"Okay, okay, then you can look here...", the ship's teeth temporarily suppressed their anticipation, and pointed to the bow of the ship to continue to introduce,

"The bow is designed to be in a deep vertical mode near the waterline, with an increased forward angle in the upper part and a spherical bow at the forward end below the waterline;"

"Why is it designed like this?" Nesta vaguely felt that such a design scheme seemed to have been seen in his previous life, but the memory was a bit ambiguous....

"This design layout has two advantages: first, it further saves water discharge and improves utilization; Second, the bulbous bow can lift the drag reduction performance of the ship with the excellent linear design of the hull, and can show a much higher speed than other ship types under the premise of the same power supply. ”

"Oh? Has such a detailed conclusion been verified? ”

"I've simulated it in a meditation space, and I've tested it in real life with models and small-tonnage ships, and the results have been good."

"Hmm.... Very good, go on. ”

"Yes, in addition, in previous paper-and-pencil calculations, as well as decades of continuous practice, as well as recent shelling tests, we have also concluded the effect of hull shape on stability, and this effect will further affect the accuracy of shelling;"

"Then we came up with a hull that looks like this – a stubby shape with a curved waist on the inside and a wide hull."

"The middle part is an elliptical hull that is close to rectangular, the second front part is a trapezoidal shape with a wide rear width and a narrow front part, the front part is a sharply narrowed bow, and the last part is a large triangle with a slow retract and propeller blades underneath."

"It looks beautiful and simple, but why don't you see the chimney?"

The configuration of the upper deck of the ship is very different from that of the battleship in Nesta's impression, except for the solitary system at the stern marked 'infrasound radar', there is no conning tower and no chimney;

As far as the eye can see, it is all semi-submersible reactor chambers with thick cannon barrels, and specially marked 'all-photosynthetic decks'.

"Hey, hey... The power part will be told to you later, and I'll talk about the rest first. ”

"It's okay..."

At this time, the ship's desire to explain has been raised to the extreme, and it seems that a set of corresponding explanation ideas has been laid, so Nesta also obeyed his intention and was ready to listen to the ship's thoughts.

"Hehe, then I'll continue, we designed the four most important system modules for it, which are 'central system', 'attack system', 'power system', and 'storage system';"

"Let's look at the 'hub' first, this is the proud work of all the designers of our research institute, it is the soul area of the whole ship, and there is more than a 'command system'...."

The fingertips of the ship's teeth were on the stern propeller, in an obviously strange part, and from the structure shown on the drawings, it seemed to be a 'ship within a boat'?

Obviously, this so-called 'proud work' wanted to say it personally, so it was not marked in great detail like the rest of the area.

"This is the core of the 'hub', which integrates a number of different functional areas such as the 'Audio Analysis Room', the 'Damage Control Room', the 'Shelling and Loading Control Room', and the 'Power Control Room', which are connected to the hull through the totem structure and can directly control the corresponding functional areas of each room;"

"As you said, 'We have a small number of mouths and few soldiers, so we must do as much work as possible with the least number of sergeants', and now this arrangement allows all systems of the giant ship to achieve remote-controlled semi-automatic operation, and we can complete all operations in the center."

"We calculated that we only needed a quota of 300 sergeants to make the ship run most efficiently..... Of course, totem manipulation is high-precision work, and the necessary training is indispensable. ”

Niesta's eyes lit up when he heard this, he remembered that in his previous life, those big battleships were often more than a thousand people, and the guy in front of him, who seemed to be bigger than the Yamato, only needed 300 sergeants to operate, which was definitely good news....

Of course, this is only the result of the calculation for the time being, and the specific situation depends on the actual situation;

However, after all, the whole ship is made up of living spell plants, and a lot of work can indeed be done by controlling the living body through the totem, so what the ship tooth said should have a high reference value....

While he was pondering like this, the explanation of the boat tooth did not stop, only listening to him continue,

"I kept in mind what you said - 'the preservation of the living force is the highest priority', so when designing the 'hub', I specifically studied how to preserve the 'living force';"

"The result.... You see, the armor structure that is completely independent of the hull is only the initial insurance, and we expect to equip the 'core' with the turbine-type power system being studied, and in the event of a need to abandon the ship, we can activate the emergency separation system, push the 'hub' that was originally designed as a ship to the surface and escape alone, if necessary, we can also install some rapid-fire guns and the like, and in the future, we can also design a system that can completely submerge to the bottom of the sea.... Hey? Wait, 'dive boat'... This is good, you have to write it down, you have to write it down...."

The commentary came to an abrupt end, and the boat seemed to have forgotten what he was doing, and as he spoke, he picked up his notebook and pen and began to write as if there were no 'people' beside him;

No one at the scene bothered him at this time, even Freya, who has always been the most naughty, didn't know whether it was because there were many elf juniors at the scene, or for other reasons, and she didn't express her dissatisfaction.

After a while, after recording the inspiration, the boat seemed to finally remember what this place was and what he was doing, so he immediately put away the pen and paper. While smiling and begging for mercy from Nesta, he glanced apologetically at the researchers who had been quietly waiting for nearly ten lights.

After that, his voice sounded again,

"We plan to reserve a part of the 'high-energy concentrate' prepared by the Cave Wolf Cell Fluid in the center, which is not usually used, but can be used to enhance the operation efficiency of each totem component in an emergency escape, so as to improve the escape rate..."

"Well, it's necessary.... The cave wolf cell liquid is gone, and it can be squeezed again, and the living force is dead, but it is dead.... Yes, this cannot be omitted. ”

Nesta agreed, anyway, the 'high-energy concentrate' has no expiration date, if it is only used for escape, the consumption will not be too high, and it is completely affordable to have such a reserve.

Looking at the 'center' designed by the research institute, Nesta found that it was really a sparrow, although it was small, and since the whole ship was expected to be only 300 sergeants, this way of escape was undoubtedly very interesting;

In addition, it can be used in more directions..... For example, the 'submarine' that came to mind by the ship's own before.

The introduction of the ship's teeth, at this time, finally came to the weapon system ....

He first poured bitter water, saying that he wanted to use 520mm or even 560mm rifled guns, but the volume of the reactor was too expanded, and after retaining the necessary power and storage space, even the super ship on the drawings could not be equipped with many guns;

In addition, these two types of large-caliber guns are not mature, and the efficiency of the reactor required for them is too low, so that the reduced firing efficiency is not proportional to the increased attack power.

"Therefore, after comprehensively considering factors such as rate of fire, range, power, bullet weight, and even manufacturing convenience, we believe that it is still time to use the same 420mm main gun as the 'Bombarder 1';"

"In terms of the double diameter of the main gun, 70L can be used to maximize the efficiency of the airburst thrust, but the barrel length of 29.4 meters, coupled with the diameter of the reactor chamber of 9 meters, will reduce the number of main guns to be carried;"

"However, this problem can be partially avoided by increasing the steering elevation angle of the barrel and designing the steering action, although it is necessary to increase some totems, and the difficulty of operation and manufacturing will also increase slightly, but it can also increase more attack power accordingly."

"After such a design, how many main guns can be arranged?"

"Look here...," said the ship's teeth, pointing to the widest area in the middle of the back of the hull, which occupies about two-fifths of the deck area.

"With a semi-submersible layout and three staggered rows, an area of 130 meters long and 50-55 meters wide can be used to place a total of 30 main guns;"

"The front center is about 70 meters long, with a low width of 50 meters and a width of 25 meters at the top, which is enough to support 3-3-2-2, a total of 10 main guns;"

"The remaining 50 meters in the bow of the ship, although the deck is a triangle of 25 meters at the bottom, but the space inside the hull is not large, if you have to squeeze it in, you can also cram into three doors, but in fact, you can change some small-caliber anti-air, offshore, and even undersea weapons;"

"Then there is the 50 meters at the back of the deck, because the totem arrangement of the hub cabin is located here and underground is extremely complicated, and there are also requirements for the arrangement of the audio transceiver end on the deck, so it is also planned to install anti-air and offshore weapons;"

"Finally, below the waterline, considering that we may have to face the attack of the sea monster in the future, we have increased the attack measures on the seabed, adopting a design that can completely retract the hull and install a waterproof compartment, a total of 150 30mm underwater rapid-fire guns, 60 60mm underwater rapid-fire guns, and 15 203mm underwater armor-piercing heavy guns;"

"All of them are barrel designs that can change the firing angle at a large angle, and on the whole, there is no dead angle for underwater attacks."

"It's good.... But don't you think that attacks in these directions should be entrusted to specialized ships? There are more than 200 small cannons in total, and the required reaction compartment space and ammunition reserve space are also a considerable number when they add up, right? ”

"In addition, the activation of the reactor chamber weapon requires special energy, and the activation of armor protection also requires special energy, how much reserve space are you going to leave for the 'low-energy concentrate'?"

Source change app】

Upon hearing this, Nesta first interrupted the chatter of the ship's teeth and gave his own advice.....

And this suggestion, although it will not be 'shocked' by heavy researchers, it can be regarded as a valuable 'three-dimensional combat idea', so it was quickly written down by researchers such as Chuanya.

After seeing that the scholars had finished writing, Nesta said again,

"And the power part, looking at your ambitious plans, the power area is also full of totems for me, right? If you don't have a corresponding reserve of 'low-energy concentrate', are you going to use your hands and feet to drive the boat? ”

"Uh...."

"Okay, take the door in the back and change it slowly, and you will talk about the design of the power first..."

"Understood, ahem...."

"In the design, a total of 13 'semi-surgical high-pressure boilers' and 7 'semi-surgical re-inflated steam engines' are prepared to be equipped, and if there is room for the transformation of 'turbines';

"Using four-shaft transmission, the maximum output power of the main engine is 16,300 moose power, and the reversing power is 4,500 moose power, which is expected to make the maximum speed under non-cruising close to 40km per light hour...."

"Hehe~'Semi-magic blast furnace', 'Half-magic steam engine', sure enough...."Nesta shook his head, already expecting this result.

It's not that he doesn't like the 'half-magic method', but the energy problem at this stage is really a big trouble and a big hidden danger;

All totem operations can not be created out of nothing, when on the ground, you can rely on the root system to absorb nutrients, and its protective layer and weapon system are not at risk of completely stopping the food;

But the depth of the sea, which can often be hundreds of meters or even kilometers, and the barren conditions that can exist in some areas, mean that it must be supplemented by the energy liquid carried by the ship to activate a series of totems on the ship;

This makes Nesta feel insecure, always worried that after losing the totem, these big guys will face the risk of reducing the armor protection by 90%, the weapon system will be completely ineffective, and so on.

But.... They look really good, and that's why he 'taunts', but he doesn't really stop it...

"Alright, go on, let me hear what kind of monster you've piled up for me."

Machine Tooth is a real junior, and he can't make a dead face like Ship Tooth in front of Nesta, so he was a little nervous when he was interrupted earlier;

Now that he had received Nesta's approval, he coughed lightly, and then gathered his words and said slowly,

"The reason why 'high-pressure boiler' and 'steam engine' are prefixed with 'semi-magical' is because when designing both, they both adopt the method of totem reinforcement, within the limited weight and volume, in exchange for higher efficiency when working larger, and the idea of safety critical threshold."

"For example, the 'high-pressure boiler' has been changed from 'charcoal boiling water' to 'totem heating', and the structure is divided into 'armor protection outer wall', 'heating interlayer', 'heat conductive metal', and 'pressurized inner wall', and the functions of each part are basically consistent with the name;"

"Although the power system is still boiling water from the overall point of view, there is no open flame, no exhaust gas, higher space utilization, higher heat utilization, and it will be more efficient and safer than before."

'Sure enough, it's a totem monster that lies on its stomach without energy....'

Nesta instinctively slandered in his heart, but after thinking about it, weren't those coal-burning and charcoal-burning ships in his previous life also like this?

After figuring this out, he was a little more receptive to these things, and instead cared about the energy reserves in the hull.
