Chapter 59 Supercavitating Thruster!

Angel Beach Resort, Fira Beach Hotel.

Open-air roof, large infinity pool.

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

Picking up the coconut juice next to her, Meimei took a few gulps.

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

The successful promotion of flying cars has made the valuation of Emerald Island directly exceed the $300 billion mark!

And Jiang Cheng's island owner level also came to Lv3.

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

However, at this time, Jiang Cheng did not care about other modules, but locked his sight on the black tech store that suddenly appeared.

The black tech store, as its name suggests, is full of technologies or products that non-humans can achieve with their current knowledge and scientific level, and every item they take out can cause a shock to the world.

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

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

Supercavitating thruster!

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

He has actually heard of this technology for a long time, but it has always existed in science fiction. Even if some developed countries are studying it, there is still a long way to go before it is actually 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 water vapor ditch will be formed at the tail, wrapping the part of the object in contact with the water. It is greatly reduced, only 1/800 of that of water, which is the "supercavitation phenomenon".

There are generally three ways to form a "supercavitation".

First, increase the speed of the vehicle.

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 cavitation.

The first two methods are formed by natural supercavitation, which is extremely difficult to achieve. Only the last method is the method that can be achieved by manpower.

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 made with supercavitation technology can achieve a maximum underwater speed of 1549m/s, which is even more than 3 times the speed of sound in the standard state!

It's the ultimate metamorphosis!

Just imagine, if this supercavitating torpedo is vigorously developed and manufactured, 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 the water!

Of course, this is only theoretical, 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 also 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 allows 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.

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

There are many application scenarios of supercavitation technology, including various ships, ships, and various underwater equipment. If this technology can be put into practice, it can even change to some extent. 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 ten minutes, Jiang Cheng looked away.

It has to be said that the black technology product of the supercavitating thruster is really a metamorphosis.

According to the above introduction, this product can be directly applied to existing ships, which can greatly improve the moving speed of ships. 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 was very satisfied.

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

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

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

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

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

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

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

【Name】：Supercavitating thruster

[Nature]: dedicated to ships

[Maximum speed]: 142 knots

[Cost]: 19.5 million US dollars

[Time-consuming]: none

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

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

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

As far as he knows, the cost of an ordinary carrier is about $30 million to $5,000. Only a super-large natural gas carrier like LNG will cost more than $100 million.

However, the cost of the thruster in front of it is as high as nearly 20 million US dollars, and this does not include the power system and operating system that is matched with it.

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

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

However, if you can get more than three times the speed at twice the cost, it seems to be worth it.

When Jiang Cheng's eyes were placed on the speed of the supercavitation thruster, he immediately showed an excited look.

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

142 knots is 263 kilometers per hour, and this speed can almost catch up with the speed of the land high-speed rail!
