Transcendent Journey

crash-bang…

A long and narrow black silhouette splits the blue waves like a sharp arrow, and shoots towards the depths of the Black Sea, behind which the waves surge Leave a long white line.

Despite the assistance of witchcraft, the battleship outfit still spent nearly a month in the “living chemistry school” with Ivan and Angie as the main force. At this time, the time has come to July, and it is also the 3rd day when this battleship officially enters the sea trial phase.

The location is in the depths of the Black Sea where wind and rain, huge waves and hurricanes are frequent after entering the rainy season. Sailing at full speed in order to test the power system, they have traveled nearly half the distance of the old and new continental routes.

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 including the command room and the bridge.

Ivan sits in his exclusive command position, watching the rows of sailing parameters projected on the light curtain in front of him, the battleship status, speed, course, latitude and longitude… The gold talisman of gems is controlled at any time, which is the battleship “key” that represents the highest manipulation authority.

Because all the designs are carried out around the “ship spirit”, there is almost no key position for the human crew. In the current situation that the “ship spirit” is temporarily missing, equivalent to one person assumes the normal warship. The workload of a hundred people.

At this time, apart from Ivan and Nymph, who are both upper-level wizards, there is no third person on the ship who has this ability for the time being. But as long as the ship spirit can be awakened, even a little child who doesn’t 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 battleship enter the best condition, and it will come to the time when the [activated ship spirit technique] is greatly showing divine might.

So everyone dare not careless.

“Ivan, I didn’t expect that the bronze blades of the difference between Heaven and Earth compared with the sails could really easily drive such a large battleship to sail at high speed. You said that the Steam Fortress would This kind of propeller is the one that doesn’t know how to use it?”

Olivia, wearing a capable military uniform, is standing next to Ivan. Even though she has been out to sea for several days, she still feels that this ordinary thing can be used. The power out is simply more magical than witchcraft.

“Probably, although I have not personally visited the’Legendary battleship’, the technical reserves of the alchemy school really should not be underestimated. In addition, the propeller is of course important, powered by the’frog divine gold crown’ The power system is the key.”

Ivan laughed, the technical route is clear to him, so don’t use it too happily.

After deciding to build an abandoned sail for a modern warship, he immediately used a propeller made of nickel-aluminum bronze alloy enchantment in one step, and the bulky “paddle wheel” jumped directly over it.

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

Moreover, the force change itself is very complicated. The use of steel and other materials with too high rigidity can easily cause 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 difficult 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, trim, roll, diameter, disk surface ratio (the area contained in the extension profile of each propeller blade and the area of ​​the propeller disk) are all related to it.

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

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

Rely on the scattered memories in the mind: thrust is proportional to the product of mass and acceleration in the water; ship speed also depends on the thrust provided by the propeller and the collection of various resistances; blades The smaller the number, 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, I finally adjusted a close to perfect product, 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 double-propeller mode design, which is stronger than a single propeller and is also a common choice for modern cruisers.

On the back of the propeller, there is a rudder pointing down vertically, which changes direction by controlling the direction of the water flow agitated by the propeller.

As for the core power system of battleship, the best energy for Ivan in mind has always been “magnetite”, which can transform the brilliance of the sun into infinite energy, which can be used for production and Turn into a thunder to destroy the enemy.

It can also convert between light energy, heat energy, electrical energy, mechanical energy and other energy at will. It can be said that it is a force that can change the world.

But because of the most cutting-edge achievements of “Magnetite” so far, it is only a “transcendent battery” replaced by aquamarine. If transcendent energy such as alchemy stones and aquamarine is used instead, energy efficiency will inevitably be reduced, and the battle strength of the battleship will be further reduced.

But in the fourth volume of the complete harvest, one of a series of witchcraft recorded in the [Activating Ship Spirit Technique]-[Energy Core·Life Tree Touch] has provided Ivan with new Ideas.

Because this is the technology applied by the transcendent energy supply system in the super-giant rock golem “Mountain Giant”, which uses the rituals containing the ten elements to draw the power of the transcendent treasure.

Theoretically, the stronger the treasure is, the stronger the output of the “mountain giant”.

The attack power of reaching the fourth rank transcendent at the strongest is no problem at all. At least when it was strong against Kraken, the king of sea monsters, the original attack of the son of Seagod “White Skeleton” was enough.

Moreover, there are no restrictions on the types of treasures. For example, the “Misty Silver Lamp” and “Blue Orbs” that were stored in the crypt can be used as transcendent energy.

And Ivan’s hand happens to have a powerful treasure “frog divine gold crown” that I don’t know how to use for the time being. It emits strong energy radiation at any time, and it is enclosed in a hollow rune copper. In the ball, it is not a waste to become a temporary substitute for the core of battleship power.

Wait later to make a “magnetite” and then replace it.

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

This is also the case.

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

Ivan’s semifinished product battleship 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, the realization of this terrifying speed has another merit, that is, this battleship can be called an excellent aspect ratio.

Flying shears with the fastest speed of 14 knots in the sailing era have a length-to-width ratio of more than 6:1, but the ratio of this battleship with a length of 132 meters and a width of 16 meters has exceeded 8: 1. It can be called the most wooden battleship.

I didn’t dare to practice when transforming the “Venus”, but building a new battleship that does not require side cannons did not have this problem.

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

Reducing the area of ​​the hull contacting 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 battleship is based on the “bulb-nosed bow” of modern ships. Wave resistance.

Ivan also integrated the improved “Song of Sea Monster”, which not only has the ability to kill sea monsters when launching “infrasound”, but also can be transformed into “ultrasound” to act as [sonar] , Discover underwater targets such as reefs, sea monsters, etc.

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

Originally [sonar] is a technology for navigation and ranging through electroacoustic conversion and information processing. The key point is not ultrasound, but electroacoustic conversion and information processing. But as long as the ship’s spiritual sense wakes up, there is no need for electro-acoustic conversion at all, and it can be handled directly by the ship’s spirit.

As for now, Ivan needs to activate his spirit strength field “manually” control.

While explaining the principles of these devices for Olivia, Nymph, Milan, Angie, and a group of students, Ivan suddenly moved in his heart.

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

Through [sonar], I found that there was a place forty kilometers in the direction of eleven o’clock. Huge creatures moving fast. 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.

next moment, the seagull “spirit net network” as a reconnaissance system also found a huge 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 the gunfish is 320 meters long. It has surpassed the limit of the large species and ran all the way towards the 500-meter giant species.

There is no doubt that this is a 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 launching mission of the first [Hurricane Missile] will be handed over to you.”

“Yes, Captain! Make sure to complete the task!”

In the enviable gaze of everyone on the side, Olivia saluted the military salute seriously, and reached out to take the battleship “key” handed by Ivan.

Then hold the gold talisman inlaid with emeralds, connect to the weapon system after the battleship outfitting is completed, and lightly tap the Spiritual God light on the [transcendent weapon·missile silo].

Slap——

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

There is an emerald green rune on the wall of the well.

Immediately.

sou! sou!

Suddenly violent wind erupted on the deck.

The metal warhead pulled by a high-speed rotating low-pressure cyclone (temporarily energized element spirit) soars into the sky at a speed close to 340 meters per second.

After taking off, the two warheads with a payload of 10kg spread out a pair of small metal wings to assist in flight, and flew towards 11 o’clock under the positioning of the “spirit net 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 “spirit net network”, it can strike as far as 1,300 Goals beyond kilometers.

At this time.

Everyone on the bridge accesses the “spirit net network” at the same time, watching nervously the first actual combat of this ultra-long-range weapon. If it succeeds, it means that the conventional strikes beyond the visual range will completely win the dominance of naval battles for one’s own side.

It is possible to make one pick ten, one pick a hundred, and even completely ignore the number of ordinary battleships!
