Chapter 59 Supercavitation Thruster!

Angel Sands Resort, Fira Beach Hotel.

Open-air roof, large infinity pool.

Jiang Cheng swam back and forth in the pool comfortably for a few times, then surfaced, and lay on his back on the beach chair.

Picking up the coconut juice next to her, Meimei drank a few swigs.

Immediately afterwards, Jiang Cheng took out his mobile phone and opened the Tycoon app.

The successful promotion of flying cars has made the valuation of Emerald Island directly exceed the US$3000 billion mark!

And Jiang Cheng's island owner level has also reached Lv3.

In this way, all the building blocks and other modules of the system are unlocked, which makes Jiang Cheng very excited.

However, at this time, Jiang Cheng didn't care about other modules, but locked his eyes on the black technology store that suddenly appeared.

The black technology store, as the name suggests, is full of technologies or products that are beyond the reach of human beings with current knowledge and scientific level. Every item can cause shocks in the world.

However, there are only a few technologies and technologies in the system store at this time, including "zombie" Internet of Things, "slug" superglue, artificial intelligence and so on.

Jiang Cheng flipped through it casually a few times, but was not too interested, so he focused his attention on the last product.

Supercavitation Thrusters!

Seeing this, Jiang Cheng's eyes lit up like searchlights.

He has actually heard of this technology long ago, but it has always existed in science fiction. Even though some developed countries are researching it, there is still a long way to go before it can be put into practice.

The so-called "supercavitation" is actually a physical phenomenon.

When the speed of the object in the water exceeds 185km/h, a strange large-scale water vapor ditch will be formed at its tail, wrapping the part of the object in contact with water. At this time, the medium in contact with the object changes from water to water vapor, so the resistance Significantly reduced, only 1/800 of water, this is the "supercavitation phenomenon".

There are generally three ways to form "supercavitation".

One, increase the speed of the flying body.

Second, reduce the flow field pressure.

Third, in the case of low speed, the method of artificial ventilation is used to increase the internal pressure of the cavity.

The first two methods form natural supercavitation bubbles, which are extremely difficult to realize. Only the last method is the method that can be achieved by human beings.

The "supercavitation technology" is to use the third method to artificially release some gas around the moving object in the water, so that the resistance to its movement is greatly reduced.

Theoretically, torpedoes manufactured using supercavitation technology can reach a terrifying underwater speed of up to 1549m/s, even exceeding three times the speed of sound in the standard state!
It can be called the extreme of perversion!
Just imagine, if we vigorously develop and manufacture this kind of supercavitating torpedo, what else in the world can intercept the attack of underwater torpedoes! !

This technology is definitely the ultimate nightmare for all moving objects above and below water!

Of course, this is only in theory, and there are also great technical difficulties, which have not yet been put into practice.

However, this can be said to be a development goal and the development direction of future ships.

The problem of water resistance has always been the biggest problem restricting the development of the shipping industry.

The supercavitation technology has allowed the world to see the bright future. As long as this problem can be solved, it will definitely be of great help to the development of the shipping industry, and even defeat the aviation industry from now on.

Behind this technology, there are amazing development prospects.

A fiery light radiated from Jiang Cheng's eyes, and he felt that his chance to take off had come.

There are many application scenarios of supercavitation technology, including all kinds of ships, ships, and various underwater equipment. If this technology can be put into practice, it can even, to some extent, change this world!
Thinking of this, Jiang Cheng couldn't wait to click on the introduction of the supercavitation thruster, and then began to browse.

After a full 10 minutes, Jiang Cheng looked away.

It has to be said that the supercavitation thruster, a black technology product, is really extremely abnormal.

According to the above introduction, this product can be directly applied to existing ships, which can greatly increase the moving speed of the ship. Of course, some power systems and operating systems need to be adjusted accordingly, which will make the cost of the ship straight promote.

But even so, Jiang Cheng felt very satisfied.

You must know that in the modern shipbuilding industry, the most difficult technical indicator to improve is the speed of the ship.

Of course, to some extent, this is related to the ship engine industry, but more importantly, it is the problem of reducing underwater resistance.

Therefore, in the current shipbuilding industry, in order to increase the speed of the ship, most of the methods are to reduce the weight of the ship, that is, by developing some lightweight composite materials to reduce the resistance of navigation in water, so as to achieve the purpose of increasing the speed of the ship.

However, the effect of increasing the speed by this method is extremely limited, and the cost is not low.

The emergence of supercavitation thrusters has solved this problem well, which is definitely a subversive technology for the contemporary shipbuilding industry.

Jiang Cheng tapped his fingertips, and the three-dimensional model of the supercavitation propeller was clearly displayed in front of his eyes. At the same time, a series of related technical parameters also appeared.

The supercavitation thruster in front of me is a huge shuttle-shaped structure with a long protruding nozzle on the head. The surface is painted in a dark black, which looks very sci-fi.

【Name】：Supercavitation thruster
[Property]: dedicated to ships
【Maximum speed】: 142 knots

[Cost]: 1950 million US dollars
[Time-consuming]: None

[Evaluation]: The first generation concept-level supercavitation thruster, the core of the future ship power system.

Seeing the cost of the supercavitation thruster, Jiang Cheng clicked his tongue, shocked for a while.

It has to be said that the cost of the supercavitation thruster is still extremely high.

As far as he knows, the cost of an ordinary transport ship is between US$3000 million and US$5000. Only a very large natural gas carrier like LNG can cost more than US$1 million.

However, the cost of the thruster in front of it is as high as nearly 2000 million US dollars, and this does not include the supporting power system and operating system.

It seems that this so-called black technology is really not given for nothing.

If Jiang Cheng's shipyard applies this technology in the future, the cost of the ship will at least double.

However, if you can get twice the cost in exchange for more than three times the speed, it seems to be very worthwhile.

When Jiang Cheng's eyes were on the speed of the supercavitation thruster, he suddenly showed excitement.

In the modern shipbuilding industry, it is very difficult to increase the speed by even 1 knot, but the supercavitation thruster can reach 142 knots, which is really a miracle!

142 knots is 263 km/h, and this speed can almost catch up with the speed of land high-speed rail!
