There are two types of hovercraft.

One is a fully cushioned lift with an air propeller forward, with the propeller on its back above the hull.

This type of hovercraft is usually used for small and medium-sized vessels, and since there is no power plant at the bottom of the hull, it can travel short distances in swamps, shallow water, ice, and even sand and mud.

The advantage of this construction is that it can land on the beach and is suitable for military use. However, because the propeller does not come into contact with water, the power consumption is wasted, and the speed usually does not exceed fifty knots.

Another sidewall type used by the Humpback Whale relies on liftable metal sidewalls to prevent air escape, minimizing the hull contact area with the water.

This structure cannot be used to grab beaches, let alone drive in swamps or mud.

However, this structure is very suitable for large ships, and at the same time, the propeller is in contact with water, and the power consumption is greatly reduced, both in terms of speed and range, which is far beyond the previous one. It's just that the technical difficulty of this structure is quite large, and at the moment there are no examples of ships of more than two thousand tons built by various countries.

In the cockpit, two metal experts stand in the power console position.

With Ye Qing's order, the two auxiliary electromagnetic engines of the Humpback Whale started. Below the waterline, two full-motion waterjets at the bottom of the hull slowly pushed the humpback whale out of the sealed slipway.

The Humpback Whale, which can carry 20,000 tons of cargo, is extraordinary, even if it slows down. For a time, the waves inside the slipway rolled and the torrent splashed.

When the humpback whale completely disappeared from the slipway and entered the ocean, I don't know if the heavens and the earth trembled, or if the thunderstorm in the weather forecast was long overdue.

Anyway, at the end of Longxi Bay, suddenly a lightning bolt that pierced through the sky and the earth struck in the air, and dozens of seconds later, thunder rolled in.

A song "Testimony of Mountains and Seas", accompanied by rolling thunder, was transmitted in the cockpit.

After the rendering of Dolpeid's sound effects, this one of the few songs created by Xu Ninggong, which is particularly majestic, makes Ye Qing feel an indescribable mood with thunder and lightning in front of him.

"The green mountains swear an oath, and the sea is together. ”

"Is it eternal at this time..."

"The white clouds are gone, and the rivers are long..."

"Boom~"

There was another thunderstorm, and Ye Qing laughed heroically, "The target is the high sea, and after leaving Longxi Beach, go at full speed." ”

"Yes, boss. The metal expert quickly entered a series of commands on the console, and the next moment, the seemingly ordinary semi-curved porthole in front of him suddenly changed its appearance.

They have changed from colorless to a pale green.

Standing in the cockpit and looking over, the pitch black world outside the porthole also changed color. It's similar to the green color of night vision devices, but its imaging effect is extremely clear, whether it is the ripples on the surface of the sea or the outcropping reefs, there is no difference between looking at it in the daytime.

This is a laser night vision system, which has a farther visible distance than the current mainstream low-light night vision devices, and can be used normally even in an environment without any light source at all.

The porthole glass not only provides images of the front, but also the left and right sides of the Humpback Whale and the tail of the Humpback Whale, as well as automatic target identification and heat source detection functions.

When the third thunder flashed between the sea and the sky, the humpback whale had already sailed out of Longxi Bay along the channel.

Ahead is the vast sea as far as the eye can see, and the sky is full of thunder and lightning.

At this moment, the two main electromagnetic engines exploded instantly.

What is the concept of a single electromagnetic engine with a power of 200,000 kilowatts?

Taking aircraft carriers as an example, the USS Bush, the most powerful aircraft carrier in Nimitz, has a total power of 270,000 kilowatts, but this is only the power of a nuclear reactor.

When mechanical work is done, there will inevitably be power loss. At the same time, when starting the large wheel set, it must be gradual.

The cockpit conveys the command to move forward at full speed, and the command is fed back to the wheel block, and the steam injected into the gas turbine will gradually increase, and the speed of the turboshaft will increase, so that more power can be transmitted to the propeller through the wheels.

A series of speed-up times, which take five to ten minutes. In the end, the power of the propeller burst out could not exceed 200,000 kilowatts.

And what about electromagnetic engines?

It is an all-electric drive, and the nuclear reactor drives the ultra-supercritical unit. The unit is only used to generate electricity, and it only takes two seconds to go from a stationary state to the maximum burst power of the electromagnetic engine.

Even if the ultra-supercritical unit is in a low-power working state, it only needs to reserve power supply for two minutes to achieve power output balance when it bursts at full speed.

Two 200,000-kilowatt electromagnetic engines exploded at the same time, and the waves behind the humpback whale, which were originally relatively calm, suddenly seemed to be dropped into a row of depth charges. The waves erupted dozens of stories high, and the front of the humpback whale's hull also suddenly injected a strong air flow towards the transmission.

The flattened hull was isolated from the sea, and these currents were compressed by the humpback whale's own weight into a thin stream of high-pressure air that fled in all directions, lifting more of the hull and heading towards the outside of the hull.

It's just that a layer of flexible metal sidewall rising from the bottom of the humpback whale prevents this high-pressure air from passing through.

Within two seconds, the two main electromagnetic engines accelerated from a standstill state to 30,000 revolutions per minute, driving two full-motion waterjet thrusters at the tail.

At this moment, Ye Qing felt that the entire heaven and earth, every cell in the body, was roaring with the loud noise created by the electromagnetic engine.

Even though Ye Qing was already sitting in a seat with mechanical shock absorption and firmly fixing himself with a seat belt, Ye Qing also had the illusion of sitting on the Shenzhou 5 rocket.

The Humpback Whale went from 10 knots to 130 knots in just ten seconds. Converted to kilometers, it is a speed of 240 kilometers per hour in ten seconds.

The huge thrust pressed Ye Qing firmly on the back of the chair, Ye Qing turned his eyes with difficulty, and saw the two metal experts firmly fixed in place like metal piles, and also saw the percentage electronic power dial, and the output power was fixed at 62%.

This is the maximum speed at which the Humpback Whale sails normally, but it is not its maximum power output.

After full load, at this speed, it is its maximum output power, and it is also the cruising speed that it can maintain for a long time.

No way, who let it carry a nuclear power reactor.

For a short period of time, the Humpback Whale can still soar, but that will wear out the waterjet propulsion equipment violently.

In the one hundred and thirty knot speed mode, half a minute passed before all the discomfort on Ye Qing's body disappeared.

At the same time, the sea surface is relatively calm, and after the humpback whale enters the full speed cruising state, the entire hull remains quite stable. It's just that the noise from the waterjet is particularly loud, and if there is a ship close to the vicinity, the people on board will definitely have the feeling of thousands of horses galloping when visiting the flood discharge of the barrage dam.

At this time, don't think about going out of the cabin to enjoy the beautiful view of the ocean.

With Ye Qing's physique, as soon as he stepped out of the hatch, he would immediately be blown into the sky by the oncoming wind.

The noise in the cockpit was isolated to an uncanny degree, and only the occasional humpback whale took short distances over the waves that the small, violent jolts at high speeds were noticeable.

In the dark of night, the humpback whale swept close to the surface of the sea like an arrow from the string.

Occasionally, a bolt of lightning pierced the sky to be seen, and there was no trace of the humpback whale emitted by visible light.

Ye Qing listened to the surging songs one after another, feeling the stimulation of strength and speed.

At some point, a torrential rain suddenly hit the humpback whale.

The specially modified Automatic Identification System (AIS) is constantly working, marking ships within 20 nautical miles of the Humpback Whale, and the ship's radar is constantly searching for nearby targets. According to the track and inertia, the electronic chart constantly marks the location of the humpback whale.

Modern ships use GPS navigation, but humpback whales don't.

On the electronic chart, the humpback whale avoids commercial shipping lanes and moves straight ahead.

It doesn't matter where it lies ahead.
