"If you want to push such a big guy, you have to have a fairly powerful power system, right?" Roosevelt sat in his wheelchair and continued to look at the two-million-ton aircraft carrier and said to Jeffrey.

Even if you are a layman, you can definitely see that the motivation required for this is astronomical.

Hearing Roosevelt's words, Jeffrey explained to Roosevelt as if he were selling his own knowledge: "The amount of power system needed depends on the design index we give to the boat." For example, if our battleship, which is designed to speed at 30 knots per hour, requires 200,000 horsepower, then the speed reaches 35 knots, and the power required will reach a terrible 400,000 horsepower. ”

This is the terrible cubic shape, and if the speed is higher, it will be to the fourth power, and it will be even more perverted.

Another meaning of this sentence is that if you reduce the design speed, you can greatly reduce the power system required, in later generations, hundreds of thousands of tons of oil tankers, the power system used, and thousands of tons of frigates The power system power is almost the same, not afraid of slow, as long as it can move, it is a big deal to hang at sea for a few more days, and not in a hurry.

The navy is not too ambitious, if such a big guy proposes a speed that matches the fleet, it will definitely not be possible, and now, only ten knots of speed, after his own calculations, it is no problem.

Hearing Jeffrey's words, Roosevelt said: "That is, our supercarrier, will be as slow as a snail?" ”

This metaphor embarrassed the people present, and Jeffrey hurriedly came over to round the field: "President, it seems that snails can't crawl in the sea, right?" It's also compared to sea turtles, don't look at turtles are very slow on land, but in the water, they are also quite agile. ”

As he spoke, Geoffrey made a turtle swim motion.

Roosevelt laughed, and so did the others, and in the midst of the laughter, Jeffrey gave the order for the sea trials.

If it is an ordinary ship, the leaders of these countries can be allowed to get on the ship and go out for sea trials with the ship, but this ice aircraft carrier, for the first time in history, no one can guarantee how reliable this ship is, in case it goes out, it will break when it runs, and what if Roosevelt and others are thrown into the water?

So, Roosevelt didn't offer to go up, and neither did the others, and everyone was on land together, watching the behemoth move.

"Start the engine." Jeffrey shouted loudly, at this time the ship had not been connected to the radio, not even the superstructure, there was only one hull, so Jeffrey could only shout into a megaphone.

Hearing his voice, the people on board the ship began to get busy.

Start the fuel pump, fill the fuel, turn on the circuit, and ignition!

"Buzz, buzz." Puffs of black smoke came out of the exhaust pipe, and with a roar, a 2,000-horsepower star-shaped air-cooled engine was started.

One, two, when all 26 engines were started, the roar resounded throughout the lake, and the birds in the distance were disturbed by this sound, flapping their wings, flying away from the lake, while flying, while turning their heads to look at this behemoth, what is it, so terrible?

"Mr. President, our aircraft carrier is about to be launched." Jeffrey said triumphantly to Roosevelt.

The aircraft carrier is about to start!

When the engine was fully started, it took a minute to run at low speed to verify that the engine was working well, and then the operator pushed all the engine throttle levers to full speed.

In an instant, the roar of the engine was even greater, and the high-speed engine drove the propeller behind it to rotate through the reducer, and the propeller was immersed in the water.

26 engines and 26 propellers form 26 water currents, which flow backwards on both sides of the aircraft carrier, and the aircraft carrier will be affected by the forward impact of this current and move forward.

Jeffrey looked at the aircraft carrier with expectant eyes, and the time passed by second, and soon, the hope on his face turned into doubt, into strangeness.

The aircraft carrier did not move.

How is this possible?

No matter how small the power is, as long as it continues to work, the aircraft carrier can still move! This is dictated by the basic momentum theorem, but now, the aircraft carrier shows no signs of moving at all.

Jeffrey turned his head and looked at Roosevelt, whose face was also full of disappointment.

If this aircraft carrier can't move, then what's the use? Roosevelt came with hope, however, did not see the results he wanted.

With this thing, can you still go to the battlefield?

"Mr. President, please wait a moment, something unexpected must have happened." After Jeffrey finished speaking, he hurried to the ice aircraft carrier.

He took three steps and made two steps, ran to the place where he stopped in one breath, and looked at the water below, only to see one engine after another, driving the propellers, stirring the lake vigorously, everything was normal, but the boat just didn't move.

What the hell is going on?

At the dock, even a tugboat can tow a much larger cargo ship, unless the power is less than the resistance, this immobility will occur.

Thinking of this, Jeffrey crouched down, quickly took out the thick information in his briefcase, flipped to the place of the power system, and then took out a pencil and quickly recalculated.

The roar of the engines continued, and the ship remained motionless, and just like that, half an hour passed, and the people on the shore were already impatient, and behind Jeffrey was scrap paper, and a dozen sheets were thrown, and finally, Jeffrey cried and stood up.

"We miscalculated the decimal point." "We miscalculated the underwater area of this aircraft carrier and miscalculated the drag, so now our power system can't drive the ship," Jeffrey said. ”

There were still too few people, and it was all calculated by hand, and the deadline was very rushed, and there was no review, and Jeffrey couldn't believe that this situation had happened.

In this era, there are no super large oil tankers, if it is a later generation, with a 300,000-ton VLCC type tanker, it will need 30,000 horsepower to meet the needs of the minimum speed navigation, if it is 2 million tons, then it will need at least 200,000 horsepower, now, each engine is only 2000 horsepower, 26 power, it is also seriously insufficient, at least 100 units are needed!
