* Whoosh … *
A long and narrow black silhouette split the blue waves like an arrow and flew into the depths of the Black Sea, leaving a long white line behind.
Despite the assistance of witchcraft, it still took nearly a month for the "School of Activation" with Elvin and Angie as the main force to equip the battleship. It was now July, the third day since the warship officially entered the sea trial stage.
The location was in the depths of the Black Sea after the rainy season, where storms, waves, and hurricanes were frequent. In order to test the ship's propulsion system, they had traveled almost half of the route between the Old and New Continents.
Although the waves in the sea were not small, the warship was still as steady as a mountain.
At the top of the tower, in the bridge that contained the command room and the cockpit.
Elvin sat in his exclusive command seat and looked at the rows of navigation parameters projected on the screen in front of him. The status of the warship, speed, direction, latitude, and longitude were all controlled by a golden amulet inlaid with emeralds in his hand. This was the warship's "secret key" that represented the highest control authority.
Because all the design revolved around the "Ship Spirit," there were almost no key positions for the human crew. In the current situation where the "Ship Spirit" was temporarily missing, it was equivalent to one person taking on the workload of hundreds of people on a normal warship.
At this time, other than Elvin and Nympho, who were both high-ranking wizards, there was no third person on the ship who had this ability. However, as long as the Ship Spirit was awakened, even an illiterate child could easily control it.
The more advanced the technology, the more "idiotic" the operation was.
After the successful sea trial, some adjustments would be made to let the warship enter the best state, and it would be the time for the "Animate Ship Spirit" spell to shine.
Therefore, no one dared to be careless.
"Elvin, I didn't expect the bronze leaves, which are so different in size from sails, to be able to easily propel such a large warship at high speed. Do you think the Steam Fortress is also using this kind of propeller?"
Olivia stood beside Elvin in her military uniform. Even though she had been at sea for a few days, she still felt that the power of this ordinary thing was more magical than witchcraft.
"Maybe. Although I have not personally visited the 'legendary warship,' the technology of the school of alchemy is not to be underestimated. Although the propeller is important, the power system powered by the Frog God's Golden Crown is the key. "
Elvin smiled. The technical route was clear to him, and he was happy to use it.
After deciding to build a modern warship to discard the sails, he directly used a propeller enchanted with nickel-aluminum-bronze alloy, and the cumbersome "paddle wheel" directly jumped over it.
This was because the propeller was a key component that allowed for a certain degree of deformation, but it was not allowed to break. Therefore, it didn't need to be too hard. Instead, it needed toughness.
Moreover, the changes in the force it was subjected to were very complicated. If it used steel or other materials that were too rigid, it was very easy to cause stress concentration and lead to fracture. Bronze alloy was the best choice.
Copper ions also had a killing effect on marine microorganisms. Even if it was soaked in seawater for a long time, barnacles and diatoms would not easily grow.
Also.
In the shipbuilding industry, what kind of ship was equipped with what kind of propeller was an extremely complicated subject. Factors such as the airfoil profile, pitch, pitch, roll, diameter, disk ratio (the sum of the areas included in the extension contours of the propeller blades is the area of the propeller disk) and so on were all related.
However, even if Elvin had not systematically studied the relevant subjects, with the help of a superior wizard's brain that was comparable to a supercomputer and the combination of "Data Analysis Vision," he could reshape the propeller at any time during the sea test.
In other words, he had the capital to try thousands of times.
Relying on the scattered memories in his mind, the thrust was proportional to the product of the mass and acceleration in the water; the speed of the ship depended on the combination of the thrust and various resistance provided by the propeller; the fewer blades, the higher the efficiency of the propeller …
The fewer blades, the higher the requirements of the material. In order to take into account reliability and efficiency, Elvin initially chose a four-blade propeller.
After many experiments, he finally adjusted the final product that was close to perfection. Because at this time, any change in the parameters would cause the speed to decrease.
Weight of a single blade: 3,500 kg; Weight of the hub: 6,500 kg; Weight of the propeller: 10000 kg; Diameter of the propeller: 4 meters. Using a dual-axis dual-propeller design, the performance was stronger than a single propeller, and it was also the common choice of modern cruise ships.
At the back of the propeller, there was a vertical downward rudder that controlled the direction of the water flow stirred by the propeller to change the direction.
As for the core power system of the warship, the best energy source in Elvin's mind had always been the "magnetic ohlite". It could convert the light of the sun into infinite energy, which could be used for production or turned into thunder to destroy the enemy.
It could also be converted between light, heat, electricity, mechanical energy, and other energy sources at will. It could be said that it was a power that could change the world.
However, because the most cutting-edge result of the "magnetic ohlite" until now was only the "extraordinary battery" that replaced the sea sapphire. If the extraordinary energy sources such as alchemy stones and sea sapphire were used instead, it would inevitably reduce the energy efficiency and further reduce the combat power of the warship.
However, in the complete fourth volume of the [Animate Ship Spirit Spell], one of the series of witchcraft recorded in the [Energy Core: Touch of the Tree of Life], provided Elvin with a new idea.
It was because this was the technology used by the Transcendent energy supply system in the super-large stone golem, the Mountain Giant. It used the ritual that contained the ten primordial substances to absorb the power of the Transcendent treasure.
In theory, the more powerful the treasure was, the more powerful the Mountain Giant would be.
At its strongest, it could reach the attack power of Transcendent Rank-4. At the very least, it was enough to resist the attack of White Skeleton, the Son of the Sea, when it was guarding Kraken, the Sea Monster King.
Also, there was no limit to the type of treasure. For example, the "Mist Silver Lamp" and the "Azure Pearl" that were stored in the underground cavern could all be used as Transcendent energy sources.
Elvin happened to have a powerful treasure that he did not know how to use at the moment, the "Golden Crown of the Frog God". It was emitting strong energy radiation at all times. It was not a waste to seal it in a hollow rune bronze ball as a temporary replacement for the power core of the warship.
He could replace it with the magnetic ohlite when he made it in the future.
After that, it would be very easy for the [Energy Core: Touch of the Tree of Life] to convert the Transcendent energy into the kinetic energy to turn the propeller.
It was also because of this.
The Steam Fortress was powered by the magically modified steam engine. Together with alchemy, it could reach a regular speed of 20 knots.
Elvin's semi-finished warship had reached an astonishing speed of 32 knots. Others would need at least two months to cross the Black Sea, but it only needed six days.
Apart from the propeller and the power core, there was another contributor to this terrifying speed. It was the warship's outstanding length to width ratio.
The fastest flying scissors in the era of sail could reach 14 knots. The length to width ratio was usually more than 6: 1. However, this warship was 132 meters long and 16 meters wide, and the ratio was more than 8: 1. It could be said to be the best wooden warship.
Back then, when he modified the Morning Star, he did not dare to put it into practice. However, building a new warship from scratch that did not require side cannons did not have this problem.
The main resistance of a ship on the water surface was divided into: friction resistance, vortex resistance, wave resistance, protrusion resistance, and air resistance. These five types of resistance increased as the speed increased.
Reducing the surface area of the ship in contact with the water, the transverse length of this part, or reducing the weight of the ship could increase its speed. The correct way to build a high-speed ship was to increase the length to width ratio, increase the sail area (power), and sharpen the bow (reducing the resistance).
The underwater part of the new warship's bow was a reference to the 'bulbous bow ship' of modern warships. It could allow the peaks and troughs of the waves formed by the hull and the bulbous nose to cancel each other out, overcoming the wave resistance.
Elvin had also integrated the improved 'Siren's Song'. Not only did it have the ability to kill sea monsters when it activated 'infrasonic waves', it could also be converted into 'ultrasonic waves' to act as [Sonar], allowing it to discover reefs, sea monsters, and other underwater targets.
Effect: Passive detection range is about 20 kilometers. Active detection range is about 50 kilometers.
Originally, [Sonar] was a technology that used electro-acoustic conversion and information processing to conduct navigation and range measurement. The key was not ultrasonic waves but electro-acoustic conversion and information processing. However, as long as the Ship Spirit was awakened, there was no need for electro-acoustic conversion. The Ship Spirit could handle it directly.
As for now, Elvin had to activate his spiritual force field to 'manually' control it.
While Elvin was explaining the principles of the equipment to Olivia, Nympho, Milan, Angel, and the other students, he suddenly had an idea.
"Eh, we seem to have found the target of the experimental weapon system."
Through [Sonar], he discovered a gigantic creature that was moving at a fast speed about 40 kilometers away from his 11 o 'clock direction. It suddenly emerged from the deep sea with a giant squid in its mouth. It was rushing towards the surface of the sea at an extremely high speed.
The next moment, the 'mental network' of the seagulls also discovered the gigantic shadow under the water from high up in the sky. It quickly locked onto the two characteristics of the creature: its carapace and tentacles.
The sea monster's true form should be a spearfish. Its body was 320 meters long, which was already beyond the limit of large sea monsters. It was rushing towards the giant sea monster that was 500 meters long.
There was no doubt that this was the spawn of the 'mother of sea monsters'. It was also the first worthy opponent that Hao Ren had encountered in the three days at sea.
"Come, Hersey. Other than the fixed target, I'll leave the first [Hurricane Missile] to you."
"Yes, captain! I promise to complete the mission! "
Under everyone's envious gaze, Olivia saluted solemnly and reached out to take the battleship "key" from Elvin.
Then, she held the golden amulet inlaid with emeralds in her hand and connected to the weapon system of the battleship. She tapped on the [Extraordinary Weapon: Missile Silo] with her spiritual aura.
Pa!
On the curved front deck of the battleship, between the turret and the turret, two round manhole covers popped open at the same time.
Emerald green runes flashed on the walls of the manhole.
Then.
Whoosh! Whoosh!
Suddenly, a gust of wind blew on the deck.
The metal warheads pulled by a high-speed, low-pressure cyclone at the tip (temporarily empowered elemental sprites) soared into the sky at a speed of nearly 340 meters per second.
After taking off, the two warheads with a load of 10 kilograms spread out a pair of small metal wings to assist their flight. Under the guidance of the 'mental network', they flew towards the 11 o 'clock direction.
The [Hurricane Missile] that was currently installed was strictly classified as a low-speed (lower than Mach 1) cruise missile. Within the range of the 'mental network', it could hit targets up to 1,300 kilometers away.
At this moment.
Everyone in the bridge was connected to the 'mental network' at the same time, nervously watching the first real combat of this ultra-long-range weapon. If it succeeded, it meant that the future conventional strikes beyond the horizon would completely win the naval battle for their side.
It would be possible for one to fight ten, one to a hundred, and even completely ignore the number of ordinary battleships!
