Chapter 739 Aircraft Carrier (5)

Just like the Ford-class aircraft carrier that the United States is about to put into service, its power system is equipped with two AIBs (B stands for Betis Nuclear Power Laboratory) and two A1B nuclear reactors are equipped with 13,500V transmission and distribution systems, with a power supply capacity of up to 200,000 kilowatts, almost three times that of the Nimitz-class 64,000 million.

In addition, the Ford class also uses a new integral engine system, originally at the beginning of the Ford class was ready to use electric propulsion directly powered by the reactor, and the electric motor driven by the reactor drove the thruster, such as the rotatable capsule pod thruster, but because the electric propulsion system used in the supply of 100,000 tons of ships The U.S. government can't get the finished product now, so the current Ford class, according to the U.S. government's plan, is that the first three Ford-class aircraft carriers will still use steam turbines to directly drive four-shaft propeller propulsion, as the propulsion power will reach 104MW about 280,000 horsepower!

But these problems do not exist here in the Starfall Group, Xiaoxi's ability to make the utilization rate of nuclear fuel in the nuclear reactor more than several times that of the United States, hearing this old professor's inquiry, Yang Yiwei thought about it, and simply told the truth, after all, the aircraft carrier will be handed over to the country for use in the future, and these things will be exposed after being used for a long time, so it is better to tell them as soon as possible, so that they can be prepared in their hearts.

"That's right, this aircraft carrier uses two Starfall I nuclear reactors developed by Starfall Group, their efficiency is very high, the power supply capacity of the two reactors is as high as 500,000 kilowatts, not only can ensure that the power of the entire aircraft carrier is sufficient, but also its nuclear reactor core and fuel can be used for 50 years, that is. It doesn't have to replace its core for 50 years, and after 50 years it can be almost decommissioned. In addition, its thruster directly uses the latest electric motor, that is, there is no steam turbine, and the electric motor thruster is directly driven by the electricity provided by the reactor, and its propulsion power is about 180MW, which is about 3600000 horsepower. This speed can greatly increase the starting speed and maximum speed of the aircraft carrier, and its maximum speed can reach a high speed of 42 knots, but this speed cannot be maintained for too long. Yang Yiwei talked about the power system of the aircraft carrier.

Lin Shengli, who was listening next to him, couldn't help but gasp, 42 knots of speed? The 150,000-ton displacement of the giant ship drove out at a speed of 42 knots? What is this concept? Even modern destroyers are almost impossible to reach this speed. Although it is not like the era when the battleships of the First World War were dominant, even the speed of 42 knots now means a higher ability to rush to the battlefield, which is good for the war even one second earlier.

Although this limit speed cannot be maintained for a long time, the speed that can be maintained can almost reach about 38 knots, right? This speed is already terrifying, and the Ford-class is only about 32 knots. Of course, speed is nothing. But the efficiency of the nuclear reactor made the two old experts in nuclear power full of excitement.

Yang Yiwei was just about to say something. Suddenly, there was a roar in the distance, Yang Yiwei's heart moved slightly, and his face was expressionless, but the chairman and the others immediately followed the sound, but because they were standing on the leading part of the deck, there was a second deck parallel to the ship island. So they can't see what's going on over there.

"What's going on over there?" The chairman asked with some curiosity, just now when Yang Yiwei explained to the old expert, several people did not stop their steps, they had already come to the place where the first deck and the second deck combined. The middle is hollow, and in the middle of the second deck is a huge hangar. There are lifts that go directly to the upper deck.

"Oh, yes, it should be the hull made in another of our dockyards that was tested today. The main thing is to test the powertrain, nothing to look at. Yang Yiwei said with an embarrassed smile, the chairman's eyes rolled, and then he thought of something, and said funny: "You kid is uneasy and kind, don't you want to make money from me?" Dynamical system? What is it? Let's see? ”

"Uh, okay, those guys, please." Yang Yiwei directly asked the chairman and others to get on the elevator from the first deck, and soon the elevator went to the second deck, and when they arrived on the second deck, the field of vision immediately became unusually wide, I have to say, the design of the two-story deck is very good, although there are shortcomings, but there is no design that is perfect, and the advantages are obvious. The angle of the second deck and the first deck is the same as that of the beveled deck of an ordinary aircraft carrier and the straight deck, the difference is that the two overlap in two layers, but they become entities at the edges, and even so, the width of the ship has to be increased to more than 100 meters.

The width of the ship is not as wide as possible, the US aircraft carrier once made a design, and the 100-meter-wide deck can already be designed as a rectangle, and there is no need for an oblique deck, directly a rectangle, divided into two areas, one landing, and the other taking off. The current beveled deck is designed to continue to fly out of the deck and take off safely if the hook fails when landing, so as not to disturb the take-off operation of the straight deck.

If there are not enough advantages and benefits, no one will design the deck to be so wide, and this aircraft carrier is designed to be so wide, naturally there are enough benefits, such as such a two-story deck, it will empty up a lot of space, although it increases the weight and volume of the aircraft carrier, but this aircraft carrier seems to be steel, but it is a new material, so that the weight of the aircraft carrier is not as heavy as imagined.

What's even more rare is that on this two-layer deck, it is still like flat ground, in fact, if it can't be as stable as the Ford-class aircraft carrier, Yang Yiwei will not design it like this, there is no stability, and there are great safety risks when the plane lands. But now everyone was not in a hurry to activate the main control computer of the aircraft carrier by the chairman, and everyone looked in the direction of the voice just now.

It is also a closed dock, but it is much smaller than the dock that the aircraft carrier just came out, and at this moment a ship sailed out of it, seeing the search ship, everyone's faces were very strange, Lin Shengli asked very simply: "You still build submarines here?" "What has Yang Yiwei done. Lin Shengli knew that there were many people who knew the way, just kidding, the Virginia-class nuclear-powered submarine was still lying in a secret research institute in China.

"Well, it's not a submarine, it's just for testing the power system." Yang Yiwei quickly said that the reason why he came out at this time was that Yang Yiwei naturally didn't make it for no reason, of course, it was to make money. To put it bluntly, it's also to create some killer features.

Lin Shengli glanced at Yang Yiwei directly, although they were far away, they could see that there was no difference between that thing and a submarine. The appearance is almost identical to that of a submarine, although nothing else is visible. But at least from the looks of it. This thing is a submarine, and it seems that the displacement is not small.

"You say test the power system, what kind of power system is it?" It's still the two old professors who just asked Yang Yiwei.

"Magnetofluid thrusters." Yang Yiwei spit out a noun in his mouth.

"What?!" The two old professors exclaimed directly, one of them jumped up directly, and the other old professors also looked at Yang Yiwei dumbfounded. The reactions of several old professors frightened Lin Shengli and the others, they didn't understand what this was, but looking at the reactions of these old professors, they knew how amazing this thing was.

"What's this magnetofluid thruster?" The chairman asked dryly. The chairman asked, but this time Yang Yiwei did not answer. Seeing that Yang Yiwei didn't mean to explain, the excited old professor simply spoke by himself, and grabbed the chairman's hand directly with both hands, his face full of excitement.

"Chairman, you must buy this technique, you must buy it." The old professor said excitedly.

At this moment, the chairman couldn't cry or laugh, he could only hold the old professor's hand and say, "You tell me what this magnetofluid thruster is first, and then I can consult with Xiao Yang to see if it is sold." ”

"Yes, yes, the magnetofluid thruster is a magnetic field established in the channel through the seawater, which can produce an electromagnetic force on the conductive seawater, so that it moves in the channel, and if the direction of movement is directed towards the stern, the reaction force will push the ship forward. The first magnetohydrodynamic propulsion was the Yamato-1, built in 1993 by Japan's Mitsubishi Heavy Industries and the Joint Foundation for Ships and Oceans. The old professor said quickly.

"Little Japan has been built a long time ago, what are you excited about?" Lin Shengli asked a little inexplicably, Lin Shengli is about the same age as these old professors, and the two sides are in the navy, so they naturally have a lot of exchanges, and they are already very familiar with each other, and a few of them are still old friends.

"You know what to say! Side, don't tell you a martial artist, the Japanese have built it, but the magnetofluid thruster has the shortcomings of the current technology, the first cost is high, the second is its slow propulsion speed, mainly because the modern technology is not up to standard, and the Yamato 1 made by the Japanese is only 30 meters long, and it has to be made of aluminum alloy to reduce the weight of only 15 knots per hour. The old professor gave Lin Shengli a direct look, obviously very familiar with Lin Shengli.

"The difference between magnetohydrodynamic thrusters and mechanical thrusters is that the former uses mechanical force, while the latter uses electromagnetic force, so the latter does not need to use propeller blades, gear transmission structure and shaft pumps, etc., it is a quiet thruster with no mechanical noise at all. Do you know how fast a submarine can reach under a few tens of decibels, or even below a few tens of decibels? The old professor was obviously not ready to let Lin Shengli go, and directly threw a question over.

"Uh...... How many knots? Since it is so advanced...... Can it reach 50 knots? Lin Shengli hesitated for a moment, and said a number that made him hesitate a little, although the speed of Russian submarines has reached the limit speed of 44 knots, but the usual speed is still only about 40 knots at most, and his own increase of 10 knots should be very high.

"." The old professor gave Lin Shengli a direct look, and then said quickly: "According to the results we calculated, the speed of the submarine can reach 150 knots!" ”

"Poof" Lin Shengli was directly choked by his own saliva, "How much?" 150 knots?! Lin Shengli shouted out in disbelief, his eyes widened, and the few admirals next to him almost all had such expressions, with a speed of 150 knots...... I'll go! This Nima can't even catch up with the torpedo, even if Russia's most famous Storm torpedo has a speed of only 200 knots, but the range of Nima's entertainment is a cripple, only about 10 to 15 kilometers, and there is no practicality at all. No matter how fast the speed is, it's a waste, which torpedo now doesn't have a range of more than 30 km?

But putting aside the old Maozi's blizzard torpedo, because there is no actual combat aside, the speed of other torpedoes is between 70 and 90 knots, and there are not many more than 70 knots. When encountering an opponent's air-to-air missile, you only need to soar at a high speed, and you don't need to do any tactical evasion actions. (To be continued......)
