Chapter 594 Sea Trials and Missiles

crash-bang

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

Despite the help of witchcraft, the battleship outfitting took nearly a month for the “living chemical faction” with Alwin and An Qi as the main force. At this time, the time has come to July, which is also the third day of the battleship officially entering the sea trial stage.

The location is in the depths of the Black Sea where rainstorms, huge waves and hurricanes are frequent after the rainy season. At full speed 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 that includes the command room and the wheelhouse.

Alwin sat in his exclusive command position, looking at the rows of sailing parameters projected on the light curtain in front of him, the battleship status, speed, heading, longitude and latitude through a gold inlaid with emeralds The Amulet is in control at any time, which is the battleship “key” that represents the highest manipulation authority.

Because all the designs revolve around the “ship spirit”, there is almost no key position left for the human crew. In the current absence of the “ship spirit”, it is equivalent to one person taking on the normal warship. Workload of a hundred people.

At this time, apart from Alwin and Nymph, who are also high-rank wizards, there is no third person on board with this ability. But as long as the ship’s spirit can be awakened, even a little child who can’t read a word can easily control it.

The more advanced the technology, the more “dumb” the operation.

After the successful sea trial, I will make some adjustments to make this battleship into the best state, and it will come to the time when the [revitalized ship spirit technique] shows great divine might.

So no one dares to be sloppy.

“Alwin, I didn’t expect that the bronze blades of the difference between Heaven and Earth, compared with the sails, can really easily drive such a large battleship at high speed. You said that the ‘Steam Fortress’ would It’s the propeller that you don’t know how to use?”

Olivia, dressed in a capable military uniform, stood beside Alwin, even though she had been out at sea for several days, she still felt that this ordinary thing could work The power out of it is simply more magical than witchcraft.

“Maybe, although I haven’t personally visited the ‘Legendary battleship’, the technical reserves of the alchemy school are indeed not to be underestimated. In addition, the propeller is of course important, powered by the ‘frog divide gold crown’. The power system is the key.”

Alwin laughed, the technical route is clear to himself, and it should not be too pleasant to use.

After deciding to build an abandoned sail for a modern warship, the propeller made of nickel-aluminum-bronze alloy enchanted was used 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 is not allowed to break. So it doesn’t need too much hardness, but more toughness.

In addition, the change of force itself is very complicated. When using materials with high rigidity such as steel, it is very easy to cause 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.

Additionally.

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 disc surface ratio (the sum of the areas contained in the stretched profile of the propeller blades/the area of the propeller disc) are all related to it.

However, even if Alwin has not systematically studied related subjects at all, but with the brain of the superior wizard, which is now comparable to a supercomputer, coupled with the “data-based vision”, the propeller can be turned on at any time during the sea trial. Reshape.

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

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

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

After many experiments, a near-perfect finished product was finally adjusted, because any parameter changes 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 dual-propeller mode design, which has stronger performance than a single-propeller and is also a common choice for modern cruise ships.

On the rear side of the propeller is the vertical downward rudder, which changes the 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 Alwin’s mind has always been “Magnetic Stone”, which can convert the brilliance of the sun into infinite energy, which can be used for both production and production. Turn into thunder and destroy enemies.

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

But because of the most cutting-edge achievements of “Magnetic Stone” so far, it is only an “extraordinary battery” replaced by aquamarine. If alchemy stone, aquamarine and other extraordinary energy sources are used instead, it is inevitable to reduce energy efficiency and further reduce the battle strength of the battleship.

But on the Fourth Volume of the complete harvest, one of the series of witchcraft recorded in the [animated ship spirit technique]-[Energy Core·Life Tree Touch] provided Alwin with new ideas. .

Because this is exactly the technology applied by the super-giant rock golem “mountain giant” in the body of the extraordinary energy supply system, using the rituals containing ten major substances to absorb extraordinary treasure power.

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

There is no problem at all with the extraordinary attack power of the fourth rank at the strongest, at least when he defended Kraken, the king of sea monsters, the body attack of the son of the sea god “White Skeleton” was enough.

And there is no limit to the types of treasures. For example, the “Misty Silver Lamp” and “Blue Orb” that were originally stored in the burrow can be used as extraordinary energy.

Alwin just happened to have a powerful treasure “frog divide gold crown” that he didn’t know how to use for the time being. In the ball, it’s not a waste to be a temporary replacement for the power core of a battleship.

Wait to make “Magnetic Stone” later and replace it.

After that, it is really simple to convert the extraordinary energy into kinetic energy that makes the propeller rotate by [Energy Core·Life Tree Touch].

And so on.

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

Alwin’s semifinished product battleship has reached a top speed of an astonishing 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 power core, there is another contribution to the achievement of this terrifying speed, and that is the excellent aspect ratio of this battleship.

In the sailing era, the fastest clipper ship that can reach 14 knots has an aspect ratio of more than 6:1, but this battleship is 132 meters long and 16 meters wide, but the ratio has exceeded 8: 1. It can be called the most wooden battleship.

I didn’t dare to practice it when I rebuilt the “Day Star”, but building a new battleship from scratch that doesn’t require broadside guns doesn’t have this problem.

The main resistance of the surface hull is divided into: frictional resistance, vortex resistance, wave-making resistance, protrusion resistance and air resistance, these five kinds of resistance increase with the increase of speed.

Reducing the area of the hull in contact with the 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 drag).

The underwater part of the bow of the new battleship is a reference to the “bulb bow ship” of modern ships. wave resistance.

Alwin also integrates the improved “sea monster song”, which not only has the ability to kill sea monsters when launching “infrasonic waves”, but can also transform into “ultrasonic waves” to act as [sonar] , discover underwater targets such as reefs, sea monsters, etc.

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

Originally [sonar] is 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, and it can be directly handed over to the ship spirit for processing.

As for now, Alwin needs to activate his own spirit strength field “manual” control.

While explaining the principles of these devices to Olivia, Nymph, Milan, Angie, and other students, Alwin’s heart suddenly moved.

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

Through the [sonar], I found that there was a place about 40 kilometers away from me at eleven o’clock. Massive, fast-moving creatures. It suddenly came out of the deep sea, biting a giant squid in its mouth, and was rushing to the sea at a very high speed.

Next moment, the seagull “spirit net network” as the reconnaissance system also found a huge black shadow under the water from high altitude, and quickly locked the two features of its carapace and tentacles.

The sea monster whose body should be a stickleback is 320 meters long, and it has already surpassed the limit of the large species and ran wildly towards the giant species of 500 meters.

There is no doubt that this belongs to the family of the “Mother of Sea Monsters”, and this is also the first opponent who is worthy of a battle since he went to sea for three days.

“Come on, Hersey, in addition to fixing the target, the first [Hurricane Missile] launch task will be handed over to you.”

“Yes, Your Excellency Captain! Guaranteed to complete the mission!”

In the envious eyes of everyone on the side, Olivia saluted solemnly, and reached out to take the battleship “key” handed by Alwin.

I then held the gold talisman inlaid with emeralds, connected to the weapon system after the battleship outfitting, and lightly tapped the Spiritual God light on the [Extraordinary Armament·Missile Silo].

Pop——

The battleship front deck with a smooth curve is located between the double-barreled naval gun turret and the tower at the front, and 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!

As violent wind erupted on deck.

A metal warhead pulled by a high-speed rotating low-pressure cyclone (temporarily energized elemental spirit) at the tip soared into the sky at a speed of nearly 340 m/s.

After lift-off, two warheads with a load of 10kg unfolded a pair of small metal wings to assist the flight, and flew away in the direction of 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 hit 1300 missiles at the farthest. target farther away.

At this time.

Everyone on the bridge was connected to the “spirit net” at the same time, watching nervously for 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 its own side.

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