There are two types of hovercraft.

One is a full pad lift that uses an air propeller to advance, with the propeller back over the hull.

This hovercraft is usually used in small and medium-sized ships. Because there is no power device at the bottom of the hull, it can travel short distances in swamps, shallow water, ice, and even beaches and mud.

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

The other type of side wall used by the humpback whale relies on the lifting of metal sidewalls to prevent air from escaping, minimizing the contact area between the hull and the water.

This kind of structure can't be rushed to the beach, and it can't be driven in swamp or mud.

However, this structure is very suitable for large ships, and the propeller is in contact with water, and the power consumption is greatly reduced. Both the speed and the range are far superior to the former. However, the technical difficulty of this structure is quite large. At present, countries have not produced more than 2,000 tons of ships.

Inside the cockpit, two metal experts stood in the power console.

With Ye Qingling, the two secondary electromagnetic engines of the Humpback Whale were launched. Under the waterline, two full-motion waterjets at the bottom of the hull slowly pushed the humpback whales out of the sealed berth.

The humpback whale that can carry 20,000 tons of cargo, even if it slows down, the momentum of carrying it is extraordinary. For a time, the waves inside the berth roll and the rapids splash.

When the humpback whale disappeared completely from the berth, when it entered the ocean, I wondered if the world was shaking, or the thunderstorm in the weather forecast was late.

Anyway, at the end of Longxi Bay, there was a sudden flash of lightning through the heavens and the earth. After dozens of seconds, the thunder and lightning came.

A "Mountain Testimony", accompanied by a rolling thunder, was transmitted in the cockpit.

After the rendering of Dubitian sound effects, this one of the few songs created by Xu Ninggong, especially the majestic songs, is the night sea and the mountain rock which are in front of the lightning field, which makes Ye Qing have an indescribable mood.

"Aoyama promised to share the sea."

“Is it always going to be at this time...”

"The white clouds are gone, the rivers are flowing..."

"Boom ~"

It was another thunder, and Ye Qinghao laughed. "The target is the high seas. After the Longxitan, it will advance at full speed."

"Yes, boss." The metal expert quickly entered a series of commands on the console. The next moment, the original half-arc porthole glass, which looked like ordinary, suddenly changed shape.

They turned from the original colorless to a faint green.

Standing in the cockpit and looking at the past, the darkness of the outside of the porthole has also changed color. It is similar to the green under the night vision, but its imaging effect is extremely clear. Whether it is the ripples on the surface of the sea or the reefs that show the head, there is no difference between watching it in the daytime.

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

The front window is not only the front image, but also the left and right sides of the humpback whale number, and the automatic recognition target function and heat source detection function.

When the third thunder was flashed across the sea, the humpback whale had already sailed out of Longxi Bay along the fairway.

In front of the vast expanse of the sea, the sky is thundering.

At this moment, two main electromagnetic engines broke out instantly.

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

Take the aircraft carrier as an example. The most powerful Bush aircraft carrier in Nimitz has a total power of 270,000 kilowatts, but this is only the power of the nuclear reactor. After the second circuit water is heated, some of it needs to generate electricity, and the rest is introduced into the gas turbine to drive the vortex. When the shaft rotates, the vortex shaft transmits power to the wheel, and the wheel drives the propeller.

Mechanical work, there will inevitably be power loss. At the same time, the main machine wheel set must be gradual when starting.

The cockpit conveys the full speed forward command, and the command is fed back to the wheel set. First, the steam injected into the gas turbine will gradually increase, and the vortex shaft speed will increase, so that more power can be transmitted to the propeller through the wheel.

A series of speed-up time takes five to ten minutes. In the end, the power of the propeller exploded could not exceed 200,000 kilowatts of power.

And the electromagnetic engine?

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

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

Two 200,000-kilowatt electromagnetic engines erupted at the same time. The still-smooth waves behind the humpback whales suddenly seemed to be thrown into a row of deep-water bombs. The turbulent waves burst out of the height of dozens of floors, and the front of the humpback whales also suddenly injected a powerful airflow.

The air flow separates the flat hull from the sea. These airflows are pressed by the humpback whale's own weight to become a thin, high-pressure air. They escape everywhere, lifting up more areas of the hull while also moving toward The outside of the hull passed.

However, a layer of flexible metal that rises from the bottom of the humpback whale prevents these high-pressure air from escaping.

Within two seconds of two main electromagnetic engines, it accelerates from a standstill to 30,000 rpm, which drives two full-motion water jet propellers at the tail. When the huge waves are blown up, the humpback whale is like a The super sports car with the ejection start mode is turned on, and it is dislocated instantaneously.

At this moment, Ye Qing felt that every cell in the whole world was roaring with the loud noise produced by the electromagnetic engine.

Even if Ye Qing is already sitting on a seat with mechanical shock absorption and firmly holding himself with a seat belt, Ye Qing has the illusion of sitting on the Shenzhou V rocket.

The humpback whale ran from a speed of ten knots to a speed of one hundred and thirty knots, which took only ten seconds. In exchange for kilometers, it was 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 hard and saw two metal experts firmly in place like a metal pile. He also saw the percentage of the electronic power dial, and the output power was fixed at 62%. on.

This is the maximum speed at which the humpback whale sails normally, but not its maximum output.

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

No way, who asked it to load a nuclear power reactor.

In a short period of time, the speed of the humpback whale can still soar, but it will wear out the water jet propulsion device.

In the 130-speed speed mode, after half a minute, the discomfort of Ye Qing disappeared.

At the same time, the sea surface is still calm, and after the humpback whale enters full-speed cruise, the entire hull remains fairly stable. Only the sound and noise of the water jet propellant is extremely large. If there is a ship near the vicinity, the people on board will definitely feel the rush of the horse when the flood of the river dam is visited.

At this time, don't even think about the ocean view.

As for the physique of Ye Qing, as soon as the hatch is released, the wind will be blown up by the oncoming wind.

The noise in the cockpit is isolated to an unimaginable agenda. Only when the humpback whales vacate the waves in a short distance can they detect the small and sharp bumps at high speeds.

In the dark night, the humpback whale is like an arrow from the string, slamming against the sea.

Occasionally, a flash of lightning cut through the sky, you can see it, there is no trace of the humpback whale from the visible light.

Ye Qing listened to one song and another song, feeling the stimulation of strength and speed.

I don't know when, suddenly there was heavy rain hitting the humpback whale.

The specially modified automatic identification system of the ship is working continuously, marking the vessel within the range of 20 nautical miles from the humpback whale. The ship radar is also constantly searching for nearby targets. According to the track and inertia, the electronic chart continuously marks the position of the humpback whale.

Modern ships use gps to navigate, but the humpback whales don't.

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

Where is the front of it.
