Angel Beach Resort, Fira Beach Hotel.
Open-air rooftop, large infinity pool.
Jiang Cheng swam comfortably in the swimming pool for several rounds, then surfaced and lay on his back on a beach chair.
I picked up the coconut juice next to me and took a few big gulps.
Then, Jiang Cheng took out his mobile phone and opened the Tropico APP.
The successful promotion of flying cars has made Emerald Island’s valuation directly exceed the 300 billion US dollar mark!
Jiang Cheng’s island owner level has also reached Lv3.
In this way, the system's building sections and other modules were all unlocked, which made Jiang Cheng very excited.
However, at this time, Jiang Cheng did not care about other modules, but instead fixed his attention on the black technology store that suddenly appeared.
The Black Technology Store, as the name suggests, is filled with technologies and products that are beyond the reach of current human knowledge and scientific level. Each one of them can shock the world.
However, at this time, there were only a few technologies and techniques in the system store, including "zombie" Internet of Things, "slug" super glue, artificial intelligence, etc.
Jiang Cheng casually flipped through it, not being very interested, so he focused his attention on the last product.
Supercavitation thruster!
Seeing this, Jiang Cheng's eyes became brighter as if they were searchlights.
He had actually heard of this technology a long time ago, but it has always been a technology that exists 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 an object in the water exceeds 185km/h, a strange large water vapor groove will form at its tail, wrapping the part of the object in contact with the water. At this time, the medium that the object contacts changes from water to water vapor, so the resistance is greatly reduced to only 1/800 of that of water. This is the "supercavitation phenomenon."
There are generally three ways to form "supercavitation".
First, increase the speed of the navigation body.
Second, reduce the flow field pressure.
Third, at low speeds, artificial ventilation is used to increase the internal pressure of the cavitation bubble.
The first two methods form natural supercavitation, which is extremely difficult to achieve. Only the last method is achievable by human power.
The "supercavitation technology" uses the third method to artificially release some gas around an object moving in the water, greatly reducing the resistance to its movement.
Theoretically, a torpedo made using supercavitation technology can reach a terrifying maximum underwater speed of 1549m/s, even three times the speed of sound in standard conditions!
It's extremely perverted!
Just imagine, if this supercavitating torpedo is developed and manufactured vigorously, what else in the world can intercept the attack of underwater torpedoes! !
This technology can definitely be called the ultimate nightmare for all moving objects above and below the water!
Of course, this is only in theory, and there are also great technical difficulties, so it has 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 underwater resistance has always been the biggest challenge restricting the development of the shipping industry.
Supercavitation technology has allowed the world to see a 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 may even defeat the aviation industry.
Behind this technology lies amazing development prospects.
Jiang Cheng's eyes radiated a fiery light, and he felt that his chance to take off had come.
There are many application scenarios for supercavitation technology, including various ships, warships, and various underwater equipment. If this technology can be put into practice, it can even change the world to some extent!
Thinking of this, Jiang Cheng couldn't wait to click on the introduction of supercavitation propulsion and started browsing it.
It was a full ten minutes before Jiang Cheng looked away.
I have to say that the supercavitation propulsion system is a black technology product that is really extremely abnormal.
According to the above introduction, this product can be directly applied to existing ships, which can greatly improve the ship's moving speed. Of course, some power systems and operating systems also need to be adjusted accordingly, which will cause the cost of the ship to increase sharply.
But even so, Jiang Cheng felt very satisfied.
You know, in modern shipbuilding industry, the most difficult technical indicator to improve is the speed.
Of course, this is related to the ship engine industry to some extent, but more importantly, it is a question of reducing underwater resistance.
Therefore, in order to increase the speed of the current shipbuilding industry, 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 the water, so as to achieve the purpose of increasing the speed.
However, the effect of increasing speed through this method is extremely limited, and the cost is not low.
The emergence of supercavitation propulsion has solved this problem very well. It is definitely a disruptive technology for the contemporary shipbuilding industry.
Jiang Cheng tapped his fingertips, and the three-dimensional model of the supercavitation thruster appeared clearly in front of him. At the same time, a series of related technical parameters also appeared.
The supercavitation thruster in front of us is a huge shuttle-shaped structure with a long protruding nozzle on the head. The surface is painted dark black, which looks very sci-fi.
[Name]：Supercavitation thruster
[Nature]：Specially used for ships
Maximum speed: 142 knots
Cost: US$19.5 million
[Time Consumed]: None
[Evaluation]: The first generation of conceptual supercavitation propulsion, the core of future ship power systems.
Seeing the cost of the supercavitation thruster, Jiang Cheng smacked his lips and was shocked.
It has to be said that the cost of supercavitation propulsion is still extremely high.
As far as he knows, the cost of building an ordinary transport ship is between US$30 million and US$500 million. Only ultra-large natural gas transport ships like LNG will cost more than US$100 million.
However, the cost of this thruster is nearly 20 million US dollars, and this does not include the corresponding power system and operating system.
It seems that this so-called black technology is not given for free.
If Jiang Cheng's shipyard applies this technology in the future, the cost of building ships will at least increase by two times.
However, if one can get a speed more than three times higher with twice the cost, it seems to be worth it.
When Jiang Cheng's eyes fell on the speed of the supercavitation propulsion, he immediately showed excitement.
In modern shipbuilding, it is very difficult to increase the speed by even 1 knot, but the supercavitation propulsion can reach 142 knots, which is really a miracle!
142 knots is 263 kilometers per hour, and this speed is almost as fast as the high-speed rail on land!
