In September, the weather is still humid and muggy.

Wang Bu'an squatted in the shed of the Sihai Legend Shipyard, concentrating on tackling key problems with a group of technicians.

Four high-powered air conditioners were installed in the shed, which was also very hot.

The long table in the middle of the shed was covered with various drawings.

The main thing is the problem of three orders.

The first is the design drawings of the integrated supply ship.

Guchengyun is not a professional. But it doesn't matter, as long as you have money, you can always find talent.

In the field of boat design, the 708 Institute is the authority within the authorities.

The drawings of the integrated supply ship were also issued by the 708 Research Institute.

However, there are only planning drawings and have not been finalized for the time being.

Because some key parameters in the middle need to be determined by Wang Buan himself.

For example, the amount of water discharged.

For example, speed.

For example, the way of supply.

Vertical, horizontal, three vertical and four horizontal...... The last one is the technical terminology.

The meaning of three vertical and four horizontal is very simple, that is, three supplies vertically and four supplies horizontally.

Figuratively speaking, it is followed by three battleships in the buttocks, and they are supplemented at the same time. Two warships were followed on each side of the side, which were also replenished at the same time.

In other words, it is possible to replenish seven warships at the same time.

Obviously, this is the most ideal state. There are no supply ships that can do it yet.

It's good to be able to do one vertical and two horizontal at the same time. It is to replenish three warships at the same time. The current integrated supply ship is basically at this level.

What are the conditions for three vertical and four horizontal?

It must be very large tonnage. There is a lot of machinery and equipment.

To replenish three ships vertically at the same time, three sets of longitudinal replenishment equipment are required.

Similarly, in order to replenish four ships horizontally at the same time, four sets of horizontal replenishment equipment are required. There should be no interplay or interference with each other.

Can it be done with a displacement of 30,000 tons?

No.

Can a displacement of 50,000 tons be achieved?

No.

What about a displacement of 80,000 tons?

I'm sorry, but with so much equipment, I still can't accommodate it.

If you want to achieve three vertical and four horizontal at the same time, you need at least 100,000 tons of displacement. If it is about 120,000 tons, it is the best.

"Then 120,000 tons!" Wang Buan resolutely finalized.

"Okay. "The ancient city cloud is on record.

The 100,000-ton dock of the Legend of the Four Seas New Shipyard can build up to 120,000 tons of ships.

Before the 300,000-ton dock was built, 120,000 tons was already the limit.

Once the final displacement is determined, all that remains is the engine.

The latest Rock 700 engine must be used.

The power of a single unit is 136,000 horsepower.

Four engines had to be installed.

According to the design requirements, all-electric propulsion is naturally the best.

However, Wang Bu'an here does not have a mature generator and motor for the time being. If you're using a product from another company, it always feels less than perfect.

In fact, this is completely obsessive-compulsive disorder. It's not my own product, so I don't really want to use it.

In particular, he himself has already begun research on electric motors.

Electric motors and generators can be summed up as a kind of equipment.

They work exactly the same way. It's just that the direction of conversion of electrical energy and mechanical energy is different.

If you can make the most advanced generator, you can also make the most advanced electric motor.

For example, the power of the generator set used in the Three Gorges Dam is very large. A single unit has a full 700,000 K. It can generate 700,000 kilowatt-hours of electricity in one hour.

Later, the newly built Xiangjiaba Hydropower Station reached 800,000 K for a single generator set. It can be described as the first in the world.

If it is reversed, the power of the electric motor is 800,000 K. Very powerful.

However, there is a big problem with these units.

It's too big.

The footprint is huge. Affects the layout.

One unit of the Three Gorges Hydropower Station weighs 6,600 tons! The weight is too heavy.

Even a 120,000-ton supply ship cannot accommodate such a large and heavy generator set. The size of generators and motors must be reduced.

However, for the time being, Wang Buan has not yet expanded the motor to the field of more than 100,000 K.

Since there is no all-electric propulsion, it is mechanical propulsion, four axles and four pulps.

The single-shaft power is 136,000 horsepower.

The four-axle is 544,000 horsepower.

I have to say that this motivation is very terrifying.

Because it was so powerful, its entire drivetrain needed to be redesigned.

A very strong propeller shaft is required.

Very strong propellers are required.

It feels like 100 million tons of hydraulic presses are not enough. Five tens of billions of tons of hydraulic presses are needed.

In particular, in the forging of propeller blades, it is necessary to use a hydraulic press of 50 billion tons to directly forge a propeller weighing more than 300 tons.

One propeller is 300 tons. Four propellers, that's 1200 tons. The parameters are very scary.

No way. This is required for a speed of 40 knots. The propeller must be strong enough.

The average large cargo ship has a speed of about 15 knots per hour.

And the speed of the integrated supply ship is required to be more than 40 knots.

Tyrannosaurus rex industrial ships are built at speeds of more than 40 knots.

If it is lower than 40 verses, please find someone else.

Verses 15 and 40, the gap is still very large. The high speed is very demanding for the propeller.

There is also the power distribution system of the entire battleship, which is also to be redesigned.

Judging from the preliminary calculation of the cable length, it is a full 12,500 kilometers.

Well, it's exactly the 25,000-mile long march.

Of course, this is a preliminary estimate.

It will definitely continue to be optimized in the later stage.

Some of the branch lines will also be replaced by hydrogen storage alloys.

However, the main power supply line is still irreplaceable. After all, hydrogen storage alloys are finite. The storage capacity is also insufficient.

Four Panshi 700 engines can provide 400,000 kilowatt-hours of electricity per hour!

It's a constant flow of electricity!

This electricity is almost cost-free!

What electromagnetic guns, railguns, and laser cannons all need this electricity.

Integrated supply ships are also weapons test ships.

A number of new types of weapons are also being prepared to be installed on it for testing.

For example, electromagnetic guns.

For example, railguns.

For example, laser cannons.

No matter what level it is at this stage, install it first.

Three vertical and four horizontal is actually unnecessary. Just a theoretical study. One vertical and two horizontal is sufficient.

In particular, if other warships are also equipped with Rock series engines, there is almost no need to refuel. This will greatly reduce the replenishment intensity of the Integrated Supply Ship.

Supplies such as ammunition, food, medicine, and sundries certainly do not need to be replenished frequently. And not a world war.

That is, previously one supply ship could only milk three or four battleships. Well, now it is possible to milk a dozen battleships at the same time.

Now it doesn't matter. The whole fleet can be pulled out. A large supply ship in the middle will do.

In particular, this 120,000-ton comprehensive supply ship can fully meet the material supply needs of more than 20 large warships. One top five.

In the past, the number of integrated supply ships was insufficient, which caused the navy to dare not send too many warships to the ocean.

Every time the Gulf of Aden escort is carried out by two warships with a wet nurse.

Even so, this nurse is also hard.

The other warships have been rotated several times, and the nurse has to continue to hold on.

It wasn't until later, when several large-tonnage nurses were launched into service, that there was finally a chance to rotate.

Why is it necessary to build a logistics supply base in Djibouti?

I can't do without this base.

If you rely solely on the wet nurse, you still can't do it.

From the coast of China to the distant Gulf of Aden, it is more than 12,000 kilometers. It's too far away.

Even the largest integrated supply ship needs to consume a lot of fuel on its own. After running 12,000 kilometers, one-third of the fuel I carried was consumed. Not cost-effective.

The Gulf of Aden is surrounded by major oil-producing countries. The oil refining industry is also well developed. Fuel can be purchased directly for reserve.

Even with large integrated supply ships, this supply base is a must.

No matter how large a supply ship is, it is not as real as a base.

We will have to build a few more similar bases in the future......

"What about the watertight data?"

"Here it is. ”

"Where's the power cabin?"

"Here it is. ”

There are many aspects involved in the design of a boat.

If there is no professional 708 Research Institute, it is difficult to rely solely on Wang Buan's strength.

The No. 1 robot elf simply simulates the various working conditions of the Rock 700, and it is already a flawless clone. If you want to participate in the design of battleships, you can't do it for the time being.

It takes time!

It feels like time is running out.

Even if there are 48 hours in a day, it doesn't feel like it's enough.

It would be nice if there was a special space. In space, time is several times or more than ten times that of outside. Then you will have plenty of time to do research.

It's just a pity that no.

That's all fantasy routines.

It was at this time that the annoying Dou family came out to make trouble again.

This time, it was Dou Jingluo who came to the door.

Dou Jingluo!

The founder of the Dou family.

President of the Westlake Provincial Shipbuilding Association. Vice-President of the Maritime Association.

His body was very strong, his skin was dark, and he had the characteristics of a seaman. Hands and feet are thick and powerful. Deep-set eye sockets. It feels very domineering and arrogant.

He arrived in a black Rolls-Royce.

Behind the Rolls-Royce, there are also five Toyota overbearing off-road vehicles. There were four big men in each car.

Every big man wears sunglasses, gloves, and a fat waist, so you can tell at a glance that he is not easy to mess with.

In front of them, Wang Buyan is simply a grass chicken.

"Mr. Wang Bu'an, he is really young and promising, and he is a hero!" Dou Jingluo sneered when he saw him.

"Thank you. Mr. Dou is the model of counterattack. Wang Buan sneered.

"I heard that the little girl and Mr. Wang had some misunderstandings?"

"Yes, no?"

"It's best if you don't have it. If there is, I'm going to help her get justice. ”

"Then what does Mr. Dou mean?"

"How old is Mr. Wang?"

"Twenty-two years old. ”

"Life is short, I hope Mr. Wang can live a long life. ”

"Is Mr. Dou threatening me and trying to find someone to kill me?"

"Of course not. It's just that there are a lot of accidents in this world. Who can guarantee that they won't suffer accidents?"

"yes!"

Wang Bu'an shrugged his shoulders and spread his hands.

That's right, life is indeed full of accidents!

But who knows who will befall these accidents, or shocks?
