Super Island Tycoon Chapter 66: Supercavitating thruster!

　　Angel Beach Resort, Fira Beach Hotel.

　　 open-air roof, large infinity pool.

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

　　 picked up the coconut juice next to me and took a few sips.

　　 After that, Jiang Cheng took out his cell phone and opened the Island Tycoon app.

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

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

　　 In this way, all the building blocks and other modules of the system were unlocked, which made 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, aptly named, is full of technologies or products that can be achieved by non-human current knowledge and scientific level. Every item can cause the world to shake.

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

　　 Makoto looked over it casually, and was not too interested, so he focused on the last product.

　　 Super Cavitation Pusher!

　　 Seeing this, Jiang Cheng's eyes became like searchlights, becoming shining.

　　 He has actually heard of this technology for a long time, but it has always been a technology in science fiction. Even if some developed countries are studying it, there is still a long way to go before it can be put into practice. go.

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

　　 When the speed of an object in the water exceeds 185km/h, a strange large steam channel will be formed at its tail to wrap the part of the object in contact with the water. At this time, the medium in contact with the object changes from water to water vapor Therefore, the resistance is greatly reduced to only 1/800 of water, which is the "supercavitation phenomenon".

There are generally three ways to form "supercavitation".

　　 One is to increase the speed of the vehicle.

　　Secondly, reduce the pressure of the flow field.

　　 Third, at low speeds, artificial ventilation is used to increase the internal pressure of the empty gun.

　　 The first two methods are formed by natural supercavitation, which is extremely difficult to achieve. The last method is the most humanly possible method.

　　 The "supercavitation technology" uses the third method to artificially move around objects in the water to release some gas, which greatly reduces the resistance to movement.

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

　　 is extremely abnormal!

　　 Just imagine, if we develop and manufacture this supercavitating fish, what else in the world can intercept underwater torpedo attacks? !

　　This technology is definitely a nightmare for all moving objects on and under water!

　　 Of course, this is only theoretically, and there are also big technical problems, which have not yet been put into practice.

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

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

　　 The supercavitating technology allows the world to see the bright future. As long as this problem can be solved, it will definitely help the development of the shipping industry, and it will even break the aviation industry from then on. .

　　 Behind this technology, there are amazing development prospects.

　　 There was a fiery light in Makoto Jiang’s eyes, and he felt that he had a chance to take off.

　　 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, he can even be able to Come, change the world!

　　 Thinking of this, Jiang Cheng could not wait to click on the introduction of the supercavitating thruster, and then began to browse.

　　After ten minutes, Jiang Cheng looked away.

　　 I have to say that the supercavitating thruster, a black technology product, can really be regarded as extremely abnormal.

　　 According to the above introduction, this product can be directly applied to existing ships, which can greatly increase the ship’s moving speed. Of course, some power systems and operating systems need to be adjusted accordingly, which will make the ship The cost of construction has increased linearly.

　　 But even so, Jiang Cheng was very satisfied.

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

　　 Of course, this is related to the ship 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, through the research and development of some lightweight composite materials, to reduce the resistance in the water, so as to achieve the increase the goal of.

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

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

　　 Makoto Jiang tapped his fingertips, and the three-dimensional model of the supercavitating thruster was clearly displayed in front of you. At the same time, a series of related technical parameters also appeared~IndoMTL.com~Supercavitating propulsion in front of you The device is a huge shuttle-shaped structure, with a long raised nozzle on the head, and a dark black coating on the surface, which looks very sci-fi.

　　[Name]: Supercavitating propeller

　　[Nature]: Special for ships

　　[Maximum speed]: 142 knots

　　[Cost]: 19.50 million US dollars

　　[Time-consuming]: None

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

　　 Seeing the cost of the supercavitating thruster, Jiang Cheng smacked his tongue, shocked in his heart.

　　 I have to say that the cost of supercavitating propellers is still extremely high.

　　 As far as he knows, the cost of an ordinary transport ship is between US$30 million and US$5000. Only a super-large natural gas carrier like LNG can cost more than US$100 million.

　　 However, the cost of this propeller in front of us is nearly 20 million dollars, and this does not include the power system and operating system that match it.

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

　　If Jiang Cheng’s shipyard uses this technology in the future, the cost of ships will at least be more than doubled.

　　 However, if you can get twice the cost of construction for three times the speed, it seems very worthwhile.

　　 When Jiang Cheng's gaze was set at the speed of the supercavitating propeller, a look of excitement suddenly appeared.

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

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