Extraordinary Sailing

clatter la la la

A long and narrow black figure split the blue waves like a sharp arrow, and flew towards the depths of the Black Sea, leaving a long white line behind the surging waves.

Despite the assistance of witchcraft, the outfitting of the battleship still took nearly a month for the "activation school" with Aiwen and An Qi as the main force. At this time, the time has come to July, and it is also the third day that the warship officially entered the sea trial stage.

The location is in the depths of the Black Sea where storms, huge waves and hurricanes occur frequently after entering the rainy season. Under sailing at full speed in order to test the power system, they have traveled nearly half of the route between the old and new continents.

Although the waves in the sea are not small, the battleship is still as stable as a mountain.

It is located at the front end of the top of the tower, in the bridge including the command room and wheelhouse.

Aiwen sat in his exclusive command position, looking at the rows of navigation parameters projected on the light curtain in front of him. The status, speed, course, latitude and longitude of the battleship can be controlled at any time through a gold amulet inlaid with emeralds in his hand. This is the battleship "key" representing the highest control authority.

Because all the designs revolve around the "ship spirit", there are almost no key positions for human crew members. In the current situation where the "ship spirit" is temporarily missing, it is equivalent to one person taking on the workload of a hundred people on a normal warship.

At this time, apart from Ai Wen and Ning Fu, who are both high-ranking wizards, there is no third person on board who has this ability. But as long as the ship spirit can be awakened, even a child who can't even read can easily control it.

The more advanced the technology, the more "fool" the operation.

After the success of the sea trial this time, make some adjustments to bring the warship into the best condition, and then it will be the time for [Activation Ship Spirit Art] to show its power.

So everyone dare not be sloppy.

"Aiwen, I didn't expect that the bronze blades, which are so different from the sails, can really easily drive such a large warship to sail at high speed. Do you think the 'Steam Fortress' will use this kind of propeller? ?”

Olivia, who was wearing a capable military uniform, was standing beside Ivan. Even though she had been out at sea for several days, she still felt that the power that this ordinary thing could exert was more magical than witchcraft.

"Maybe. Although I haven't personally visited the 'Legendary Battleship', the technical reserves of the Alchemy School cannot be underestimated. In addition, the propeller is of course important, and the power system powered by the 'Frog God Golden Crown' is the key."

Aiwen smiled, the technical route was clear to him, so don't use it too pleasantly.

After deciding to build a discarded sail of a modern warship, a propeller made of nickel-aluminum-bronze alloy enchantment was used directly in one step, and the bulky "paddle wheel" jumped over directly.

Because the key component of the propeller allows a certain degree of deformation, but does not allow fracture. So it doesn't need too strong hardness, but more toughness.

Moreover, the change of the force itself is very complicated. Using materials with high rigidity such as steel is very prone to stress concentration and lead to fracture. Bronze alloy is the best choice.

Copper ions also have a killing effect on marine microorganisms. Even if they are soaked in seawater for a long time, it is not easy to grow barnacles and diatoms.

in addition.

In the shipbuilding industry, what kind of ship is equipped with what kind of propeller is an extremely complicated subject. Factors such as airfoil profile, pitch, pitch, roll, diameter, and disk-to-surface ratio (the sum of the area contained in the extended contour of each blade of the propeller/propeller disk area) are all related to it.

However, even if Aiwen has not systematically studied related subjects at all, with the help of the brain of a senior wizard who is now comparable to a supercomputer and the cooperation of "data-based vision", he can reshape the propeller at any time during the sea test.

In other words, he has the capital to try thousands of times.

Rely on scattered memory in the brain: thrust is proportional to the product of mass and acceleration in the water; the speed of the ship depends on the thrust provided by the propeller and the collection of various resistances; the fewer the blades, the higher the efficiency of the propeller .

The fewer blades, the higher the material requirements. In order to balance reliability and efficiency, Aiwen initially chose a four-bladed propeller.

After many experiments, a near-perfect finished product was finally adjusted, because any parameter change at this time will reduce the speed.

Single blade weight: 3500kg; propeller hub weight: 6500kg; propeller weight: 10000kg; propeller diameter: 4 meters. It adopts a dual-shaft double-propeller design, which is more powerful than a single propeller, and is also a common choice for modern cruisers.

On the rear side of the propeller is a vertically downward rudder, which changes direction by controlling the direction of the water flow stirred by the propeller.

As for the core power system of the battleship, the best energy source in Aiwen's mind has always been "Magnetite", which can convert the brilliance of the sun into infinite energy, which can be used for production or turned into thunder to destroy the enemy.

It can also be arbitrarily converted between light energy, thermal energy, electrical energy, mechanical energy and other energy sources, which can be said to be a force that can change the world.

But because the most cutting-edge achievements of "magnetite" so far are only "extraordinary batteries" replaced by aquamarine. If supernatural energy such as alchemy stone and aquamarine are used instead, energy efficiency will inevitably be reduced, further reducing the combat effectiveness of the battleship.

But in the fourth volume of the complete harvest, one of the series of witchcraft recorded in [Activation Ship Spirit Art]-[Energy Core·Touch of Life Tree] provided Aiwen with new ideas.

Because this is exactly the technology used by the extraordinary energy supply system in the body of the super-giant rock golem "Mountain Giant", which uses the rituals containing the ten original qualities to absorb the power of extraordinary treasures.

Theoretically, the stronger the treasure, the more powerful the "mountain giant" will be.

There is no problem at all with the attack power reaching the fourth-order extraordinary at its strongest, at least it is enough to resist the main body attack of the son of the sea god "White Skeleton" when he guarded Kraken, the king of sea monsters.

And there is no limit to the types of treasures. For example, the "Mist Silver Lamp" and "Azure Blue Orb" that were kept in the cave at the beginning can be used as extraordinary energy.

And Aiwen happened to have a powerful treasure "Frog God Golden Crown" that he didn't know how to use for the time being. It was emitting strong energy radiation at any time, and it was used to seal it in a hollow rune copper ball, which became the power of the battleship. Temporary replacements for the core aren't wasteful either.

Wait for the "magnetite" to be made later and then replace it.

Afterwards, it couldn't be easier to convert the extraordinary energy into the kinetic energy for the propeller to rotate by [Energy Core·Touch of Life Tree].

Also from this.

When the "Steam Fortress" was powered by a magically modified steam engine and combined with alchemy, its regular speed could reach 20 knots.

Aiwen's semi-finished battleship has a top speed of 32 knots. Across the Black Sea where others take at least 2 months, it only takes six days.

In addition to the propeller and power core, there is another contributor to the realization of this terrifying speed, and that is the excellent aspect ratio of this battleship.

In the era of sails, the fastest clipper ship can reach 14 knots, and its aspect ratio is generally more than 6:1. However, the ratio of the 132-meter-long and 16-meter-wide warship has exceeded 8:1, which can be called one of the wooden warships. most.

I didn't dare to practice it when I rebuilt the "Venus", but this problem does not exist in building a new warship from scratch that does not require broadside guns.

The main resistance of the surface hull is divided into: friction resistance, eddy resistance, wave resistance, protrusion resistance and air resistance, and these five resistances become larger with the increase of the speed.

Reducing the area of ​​the hull in contact with water, as well as the transverse length of this part, or reducing the weight of the hull can increase the speed. The correct way to build a high-speed boat is to increase the aspect ratio, increase the sail area (power), and sharpen the bow (reduce resistance).

The underwater part of the bow of the new warship is a reference to the "bulb nose bow" of modern ships. It can make the crests and troughs of the waves formed by the hull and the bulbs meet and cancel each other out, thereby overcoming wave-making resistance.

Aiwen also integrated the improved "Song of the Siren" into it. Not only does it have the ability to kill sea monsters when launching the "Infrasonic Wave", but it can also be transformed into an "ultrasonic wave" to act as a [sonar] to discover reefs and sea monsters. Wait for the underwater target.

Effect: The passive detection distance is about 20 kilometers, and the active detection distance is about 50 kilometers.

Originally [Sonar] was a technology for navigation and ranging through electro-acoustic conversion and information processing. The key point is not ultrasound, but electro-acoustic conversion and information processing. But as long as the ship spirit is awakened, there is no need for electro-acoustic conversion at all, and it can be handled directly by the ship spirit.

As for now, Ivan needs to activate his own mental force field to "manually" control it.

While explaining the principles of these devices to Olivia, Ningfu, Milan, An Qi and a group of students, Aiwen suddenly felt a move in his heart.

"Hey, we seem to have found the target of the experimental weapon system."

Through [Sonar], I found that there was a huge fast-moving creature about 40 kilometers away from my eleven o'clock direction. It suddenly sprang out from the deep sea, with a giant squid in its mouth, and was rushing towards the sea surface at a very high speed.

The next moment, the Seagull "Psychic Network", which is the detection system, also discovered the huge black shadow under the water from a high altitude, and quickly locked on the two characteristics of its carapace and tentacles.

The main body of the sea monster should be a stickleback fish with a body length of 320 meters, which has surpassed the limit of a large species and rushed all the way towards a giant species of 500 meters.

There is no doubt that this is a dependent of the "Mother of Sea Monsters", and this is also the first opponent that is worthy of a battle since three days at sea.

"Come on, Hessie, besides the fixed target, I will leave the task of launching the first [Hurricane Missile] to you."

"Yes, Your Excellency Captain! Guaranteed to complete the mission!"

Under the envious eyes of everyone on the side, Olivia saluted solemnly, and reached out to take the battleship "key" handed over by Ivan.

Immediately, holding the golden amulet inlaid with emeralds in his hand, he connected it to the weapon system after the outfitting of the battleship was completed, and his spiritual aura lightly tapped on [Supernatural Armed Missile Launch Silo].

Snapped--

The curved and smooth front deck of the battleship is located between the front double-barreled naval gun turret and the tower, and two round manhole covers pop open at the same time.

Emerald green runes flickered on the walls of the well.

immediately.

Whoosh! Whoosh!

When there was a sudden gust of wind on the deck.

Pulled by a high-speed rotating low-pressure cyclone (temporarily empowered elemental spirit) at the tip, the metal warhead soars into the sky at a speed close to 340 m/s.

After lift-off, two warheads with a load of 10 kg spread out a pair of small metal wings to assist the flight, and flew towards 11 o'clock under the positioning of the "mind network".

The [Hurricane Missile] currently installed is strictly classified as a low-speed (less than Mach 1) cruise missile. Within the signal coverage of the "psychic network", it can hit targets as far as 1,300 kilometers away.

at this time.

Everyone on the bridge connected to the "psychic network" at the same time, nervously watching the first actual combat of this ultra-long-range weapon. If it can be successful, it means that the conventional strike beyond the visual range will completely win the dominance of the naval battle for one's own side.

Make it possible to pick ten, one hundred, or even completely ignore the number of ordinary warships!
