Extraordinary Sailing

Wow...

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

In spite of the witchcraft assistance, the battleship outfitting still spent nearly a month in the "living chemistry school" with Aiwen and Anqi as the main force. At this time, the time has come to July, and it is also the third day when this warship has officially entered the sea trial phase.

The location is the depths of the Black Sea where storms, huge waves and hurricanes are frequent after the rainy season. 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.

Located at the forefront of the top of the tower, in the bridge containing the command room and the wheelhouse.

Aiwen sits in his exclusive command position, watching the rows of sailing parameters projected on the light curtain in front of him, the state of the battleship, the speed, the course, the latitude and longitude...through a gold talisman inlaid with emeralds at any time For control, this is the battleship "key" that represents the highest control authority.

Because all designs are carried out around the "ship spirit", there is almost no key position for the human crew. With the current temporary absence of the "ship spirit", it is equivalent to one person taking on the workload of hundreds of people on a normal warship.

At this time, apart from Ivan and Nymph, who were both high-level wizards, there was no third person on the ship who had this ability. But as long as the ship spirit can be awakened, even a child who does not know how to read can easily control it.

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

After this sea trial is successful, we will make slight adjustments to make this warship in its best condition, and it will come to the time when the [Activating Ship Spirit Art] will show off.

So no one dare to be careless.

"Ivan, I didn't expect that the bronze blades, which are so different in size compared to the sails, can really easily drive such a large warship to sail at high speed. Would you say that the Steam Fortress uses this type of propeller? ?"

Olivia, wearing a capable military uniform, was standing next to Ivan. Even though she had been out to sea for several days, she still felt that the power of such ordinary things was more magical than witchcraft.

"Perhaps, although I have not personally visited the'Legendary Warship', the technical reserves of the alchemy school really 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 is clear to him, don't use it too happily.

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

Because the key component of the propeller allows a certain degree of deformation, but not allowed to break. So there is no need for too strong hardness, but toughness.

Moreover, the force change itself is very complicated. The use of steel and other materials with too high rigidity is extremely prone to stress concentration and cause fracture. Bronze alloy is the best choice.

Copper ions also have a killing effect on marine microorganisms. Even if they are soaked in sea water 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. Airfoil profile, pitch, trim, roll, diameter, disc surface ratio (the sum of the area contained in the extension profile of each propeller blade/propeller disc area) and other factors are all related to it.

However, even if Ivan has not systematically studied relevant subjects at all, with the help of the upper wizard's brain that is now comparable to a supercomputer, coupled with the "data-based vision", he can reshape the propeller at any time during the sea trial.

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

Relying on scattered memories in the mind: thrust is proportional to the product of mass and acceleration in the water; ship speed also depends on the combination of thrust and various resistance provided by the propeller; the fewer blades, the higher the efficiency of the propeller ....

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

After many experiments, the final product was adjusted to be close to perfect, because any parameter change at this time will reduce the speed.

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

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

As for the core power system of battleships, Ivan’s best energy source has always been “magnetite”, which can transform 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 convert between light energy, heat energy, electrical energy, mechanical energy and other energy sources at will, which can be said to be a force that can change the world.

However, the most cutting-edge achievements of "Magnetite" so far are only "extraordinary batteries" replaced by aquamarine. If supernatural energy sources such as alchemy stones and aquamarine are used instead, energy efficiency will inevitably be reduced and the combat effectiveness of battleships will be further reduced.

However, in the fourth volume of the complete harvest, one of a series of witchcraft recorded in the [Activating Ship Spiritualism]-[Energy Core·Touch of the Tree of Life] has provided Aiwen with new ideas.

Because this is exactly the technology applied by the extraordinary energy supply system in the super-giant rock golem "Mountain Giant", using the rituals containing the ten primary qualities to draw the power of extraordinary treasures.

In theory, the stronger the treasure is, the stronger the output of the "mountain giant".

There is no problem at all when reaching the fourth-order extraordinary attack power at the strongest. At least when it was hard to resist Kraken, the king of the sea monster, the body attack of the son of the sea **** "White Skeleton" was enough.

And there are no restrictions on the types of treasures. For example, the "Mist Silver Lamps" and "Blue Orbs" that were originally preserved in the crypt can serve as extraordinary energy sources.

And Ivan’s hand happens to have a powerful treasure "Golden Crown of Frog God" that I don’t know how to use for the time being. It emits strong energy radiation at any time. It is enclosed in a hollow rune copper ball and becomes the power of the warship. The core temporary replacement is not wasteful.

Wait for the "Magnetite" to be produced in the future before replacing it.

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

Also from this.

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

Aiwen’s semi-finished warship has a top speed of 32 knots. It takes at least 2 months for others to cross the Black Sea, while it only takes six days.

In addition to the propeller and the power core, there is another merit in achieving this terrifying speed, that is, this warship has an excellent aspect ratio.

The flying shear ship with the fastest speed of 14 knots in the sailing era generally has a length-to-width ratio of 6:1 or more, but the ratio of this warship with a length of 132 meters and a width of 16 meters has exceeded 8:1. It can be called one of the wooden warships. most.

I didn't dare to practice the transformation of the "Venus", but this problem did not exist in the construction of a new warship that did not require side guns.

The main resistance of the surface hull is divided into: friction resistance, vortex resistance, wave resistance, protrusion resistance and air resistance. These five types of resistance increase with the increase of speed.

Reducing the area of ​​the hull in contact with water, as well as the lateral 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 based on the "bulb-nosed first ship" of modern ships, which can make the crests and troughs of the waves formed by the hull and bulbous nose meet and cancel each other out, and overcome the wave resistance.

Aiwen also integrated the improved "Song of the Sea Monster", which not only has the ability to kill sea monsters when "infrasound" is activated, but can also be transformed into "ultrasonic waves" to act as [sonar] and discover reefs and sea monsters. Wait for underwater targets.

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

Originally [sonar] was a technology for navigation and ranging through electroacoustic conversion and information processing. The key point was not ultrasound, but electroacoustic conversion and information processing. But as long as the ship spirit awakens, 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 mental force field "manually" control.

While explaining the principles of these devices for Olivia, Nymph, Milan, An Qi, and a group of students, Ivan suddenly felt a heart move.

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

Through the [sonar], I found that there was a huge, fast-moving creature about forty kilometers in the direction of 11 o'clock. It suddenly came out of the deep sea with a giant squid in its mouth, and was rushing toward the sea at a very high speed.

In the next moment, the Seagull's "Mind Network" as a reconnaissance system also found a huge black shadow under the water from high above, and quickly locked the two features of its carapace and tentacles.

The sea monster whose body is supposed to be a lanceolar is 320 meters long, and it has surpassed the limit of the large species and ran all the way toward the 500-meter giant species.

There is no doubt that this is the family member of the "Mother of the Sea Monsters", and this is also the first opponent that he has encountered in the first three days of going to sea.

"Come on, Hessie, apart from the fixed target, the first [Hurricane Missile] launch task is left to you."

"Yes, Lord Captain! Guarantee to complete the mission!"

In the enviable gazes of everyone on the side, Olivia paid a serious military salute, and reached out to take the battleship "key" handed over by Ivan.

Immediately holding the gold talisman inlaid with emeralds, it was connected to the weapon system after the outfitting of the battleship was completed, and the spiritual aura lightly tapped on the [Extraordinary Arms·Missile Silo].

Snapped--

The smoothly curved front deck of the warship is located between the turret and the tower of the two-barreled naval gun at the forefront. Two circular manhole covers bounce off at the same time.

There were emerald green runes on the wall of the well.

Then ~www.ltnovel.com~ Whoosh! Whoosh!

When the wind was blowing suddenly on the deck.

A metal warhead pulled by a high-speed rotating low-pressure cyclone (temporarily energized element spirit) soars into the sky at a speed of close to 340 m/s.

After lift-off, two warheads with a payload of 10 kilograms spread out a pair of small metal wings to assist in flight, and flew towards 11 o'clock under the positioning of the "Mind Network".

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

at this time.

Everyone on the bridge was simultaneously connected to the "psychic network", watching nervously the first actual combat of this ultra-long-range weapon. If it succeeds, it means that the conventional strike beyond the visual range will completely win the dominance of naval battles for oneself.

It is possible to choose ten, one hundred, and even completely ignore the number of ordinary warships!
