Chapter 594

Hualalala...

a long and narrow black figure splits the blue waves like a sharp arrow and flies away towards the depth of the Black Sea, leaving a long white line behind.

Despite the assistance of witchcraft, the warship outfitting still took nearly a month for the "activation school" with Elvin and angel as the main force. At this time, the time has come to July, which is also the third day for the warship to officially enter the sea trial stage.

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

Although the waves in the sea are not small, the warships are still as stable as mountains.

It is located in the front of the top of the tower, including the command room and the cab.

Ivan sat in his exclusive command post, looking at the row after row of navigation parameters projected from the light curtain in front of him. The warship's state, speed, course, longitude and latitude... Were controlled at any time through a gold amulet inlaid with emerald in his hand. This was the warship's "key" representing the highest control authority.

Because all the designs revolve around the "spirit of the ship", there is hardly any key position left for the human crew. At present, when the "spirit of the ship" is temporarily missing, it is equivalent to one person undertaking the workload of 100 people on a normal warship.

At this time, there is no third person on the ship who has this ability except Elvin and Ningfu, who are also the upper sorcerers. But as long as we can awaken the spirit of the boat, even a child who doesn't know a word can easily control it.

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

After the success of this sea trial, make some adjustments to make this warship in the best condition, and then it will come to the time when [activate ship spirit] will have great power.

So everyone dare not be careless.

"Elvin, I didn't expect that the bronze blades, which are so different in size from the sails, can really drive such a large warship at high speed. Do you think the steam fortress will use the same propeller?"

Olivia, dressed in a smart military uniform, stood beside Elvin. Even though she had been out to sea for several days, she still felt that the power of this ordinary thing was more magical than witchcraft.

"Maybe, although I haven't personally visited the legendary warship, the technical reserves of the alchemists can't be underestimated. In addition, the propeller is of course important, and the power system powered by frog god golden crown is the key. "

Elvin smiles. The technical route is clear to him. Don't use it too happily.

After deciding to build an abandoned sail of a modern warship, we directly put it in place, using the propeller made of nickel aluminum bronze alloy enchanted, and the bulky "Ming Lun" leaped by.

Because the propeller is a key part, it can be deformed to a certain extent, but not broken. So it doesn't need too strong hardness, but more toughness.

Moreover, the change of stress is very complex. If steel and other materials with too high rigidity are used, the stress concentration will easily lead to fracture. Bronze alloy is the best choice.

Copper ions can also kill marine microorganisms. Even if they soak in seawater for a long time, barnacles and diatoms are not easy to grow.

In addition.

In the shipbuilding industry, what kind of ship is equipped with what kind of propeller is a very complex subject. Airfoil profile, pitch, pitch, roll, diameter, disk area ratio (the sum of the area of each blade stretch profile and the area of propeller disk) and other factors are related to it.

However, even if Elvin has not systematically studied related subjects, with the help of the brain of the upper wizard, which is now comparable to that of the supercomputer, and the combination of "digital vision", the propeller can be reshaped at any time during the sea trial.

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

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

the less the blades, the higher the material requirements. In order to give consideration to the reliability and efficiency, Elvin initially chose the four blade propeller.

After many experiments, we finally adjusted the product to be nearly perfect, because at this time, any parameter change will make the speed drop.

Single blade weight: 3500kg; hub weight: 6500kg; propeller weight: 10000kg; propeller diameter: 4m. The design of double shaft and double propeller mode is better than single propeller, which is also a common choice for modern cruise ships.

On the back side of the propeller is a vertical rudder, which changes direction by controlling the flow direction stirred by the propeller.

As for the core power system of the warship, the best energy in Elvin's mind has always been "magneto", which can transform the sun's brilliance into infinite energy, which can be used for production and can also be turned into thunder to destroy the enemy.

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

However, the most cutting-edge achievements of "cioushi" so far are just "extraordinary batteries" replaced by aquamarine. If the use of alchemy, aquamarine and other extraordinary energy to replace, it is inevitable to reduce energy efficiency and further reduce the combat effectiveness of warships.However, in the fourth volume of the complete harvest, one of a series of witchcraft recorded in "activating the spirit of the ship" - energy core - touch of the tree of life provides a new idea for Elvin.

Because this is the application technology of the extraordinary energy supply system in the super giant rock demon "mountain giant", which uses the ceremonial track containing ten elements to absorb the power of the extraordinary treasure.

Theoretically, the more powerful the treasure is, the more powerful the mountain giant will be.

It's no problem to reach level 4 extraordinary attack power when it's the strongest. At least it's enough to resist the ontological attack of "white skeleton", the son of the sea god, when he was guarding Kraken, the king of sea monsters.

Moreover, there is no limit to the types of treasures, such as the "misty silver lamp" and "Blue Pearl" that were originally kept in the grottoes can be used as extraordinary energy.

However, Elvin just has a powerful treasure "frog god golden crown" that he doesn't know how to use. It emits strong energy radiation at any time. It's not a waste to seal it in a hollow Rune copper ball and become a temporary substitute for the warship's power core.

After that, we can make "magnetosite" and replace it.

After that, it's very simple to transform the extraordinary energy into kinetic energy to make the propeller rotate by the energy core life tree touch.

And so it is.

When the steam fortress was powered by the modified steam engine and cooperated with alchemy, its normal speed could reach 20 knots.

Elvin's semi-finished warship, the highest speed has reached an amazing 32 knots. It takes at least two months for someone to cross the Black Sea, while it only takes six days.

In addition to the propeller and power core, there is another meritorious factor in the realization of this terrible speed, which is the outstanding aspect ratio of this warship.

In the windsurfing era, the speed of the flying shear ship was the fastest, reaching 14 knots, and the length width ratio was generally more than 6:1, but the length of this warship was 132 meters, and the side width ratio of 16 meters was more than 8:1, so it can be called the most wooden warship.

At the beginning, we didn't dare to carry out the reform of the "Venus", but there is no such problem in building a new warship from scratch without side guns.

The main resistance of surface hull is divided into friction resistance, vortex resistance, wave making resistance, protruding body resistance and air resistance, which increase with the increase of speed.

Reducing the water contact area of the hull, and the transverse length of this part, or reducing the weight of the hull, can improve the speed. The correct way to build a high-speed ship is to raise 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 "bulbous bow" of the modern warship, which can make the wave crests and troughs formed by the hull and bulbous bow meet and cancel each other, so as to overcome the wave resistance.

Elvin also integrated the improved "song of sea monsters", which not only has the ability to kill sea monsters when launching "infrasonic wave", but also can be transformed into "ultrasonic wave" to act as [sonar] and discover underwater targets such as reefs and sea monsters.

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

Originally, sonar is a technology of 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 spirit of the boat wakes up, there is no need for electro acoustic conversion, and it can be directly handled by the spirit of the boat.

As for now, Elvin needs to launch his own mental field to "manually" control.

While explaining the principles of these devices to Olivia, ninff, Milan, angel and a group of students, Evan suddenly felt a move in his heart.

"Well, 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 40 kilometers away from 11 o'clock. It suddenly came out of the deep sea, biting a giant squid in its mouth, and rushing to the sea at a very high speed.

The next moment, as a detection system, Seagull "mind network" also found the huge shadow under the water from the high altitude, and quickly locked its carapace and tentacles.

The sea monster, whose body should be a lanceochromis, is 320 meters long. It has gone beyond the limit of large species and is running all the way to a 500 meter giant species.

There is no doubt that this is the dependents of "the mother of sea monsters", and it is also the first opponent that can be worthy of a war in three days.

"Come on, Hersey, besides the fixed target, the first launch of the [hurricane missile] is up to you."

"Yes, sir! Make sure you get the job done! "

In the envious eyes of the people, Olivia respectfully saluted and reached for the warship "secret key" from Elvin.

Then, holding the gold amulet inlaid with emerald, he connected to the weapon system after the outfitting of the warship, and the spiritual light was gently on the [extraordinary armed missile silo].

Pa -

the front deck of the warship with smooth curve is located between the forward twin barrel gun turret and the tower, and the two round well covers pop open at the same time.

The emerald green runes on the shaft wall flash away.Immediately.

Whoosh! Whoosh!

On the deck there was a sudden gale.

The metal warhead, towed by a high-speed low-pressure cyclone at the tip (temporarily enabled element Sprite), soared into the sky at a speed of nearly 340 m / s.

After liftoff, two 10 kg warheads launched a pair of small metal wings to assist the flight, and flew away towards 11 o'clock under the positioning of "mind network".

Currently, the [hurricane missile] is strictly classified as a low-speed (less than Mach 1) cruise missile. Within the signal coverage of the "psychic network", it can strike targets as far as 1300 km away.

At this point.

All the people in the bridge are connected to the "psychic network" at the same time, watching the first actual combat of this kind of super long-range weapon nervously. If it can succeed, it means that the conventional strike beyond visual range will completely win the dominance of naval battle for our own side.

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