"If you want to push such a big guy, you have to have a very powerful power system?" Roosevelt sat in his wheelchair, continued to look at the two million ton aircraft carrier and said to Jeffrey.
Although a layman, I can definitely see that the power required is astronomical.
Hearing Roosevelt's words, Jeffrey seemed to show off his knowledge and explained to Roosevelt: "how much power system we need depends on the design index we give to the ship. Because when a ship is sailing at high speed, the resistance and speed are cubic. For example, our battleship has a design speed of 30 knots and needs 200000 horsepower. If the speed reaches 35 knots, the power required will reach a terrible 400000 horsepower. "
This is the terrible third power. If the speed is higher, it will become a fourth power, which will be even more abnormal.
Another meaning of this sentence is that reducing the design speed can greatly reduce the required power system. In later generations, the power system used by hundreds of thousands of tons of oil tankers is almost the same as that of thousands of tons of frigates. They are not afraid of being slow. As long as they can move, they can swing at sea for a few more days without being in a hurry.
The navy is not aiming too high. If such a big guy is given a speed matching the fleet, he will never be able to make it. Now, it only needs a speed of ten knots. After his own calculation, there is no problem.
Hearing Jeffrey's words, Roosevelt said, "in other words, our super aircraft carrier will be as slow as a snail?"
This metaphor embarrassed the people present. Jeffrey hurried to round up the scene: "president, it seems that snails can't climb in the sea? It's also compared with sea turtles. Although sea turtles are very slow on land, they are also quite agile in water. "
Then Jeffrey made a turtle swim.
Roosevelt laughed and everyone else laughed. In the laughter, Jeffrey gave the order of the trial voyage.
If it is an ordinary ship, the leaders of these countries can get on the ship and go out with the ship for trial voyage. However, this ice aircraft carrier is the first time in history. No one can guarantee the reliability of the ship. If it goes out and breaks when it runs, what should we do if we throw Roosevelt and others into the water?
So Roosevelt didn't propose to go up, and neither did the others. Everyone was on the land and watched the action of this giant.
"Start the engine." Jeffrey shouted loudly. At this time, the ship has not been connected to the radio, not even the superstructure. There is only one hull, so Jeffrey can only shout at a loudspeaker.
Hearing his voice, the people on the ship began to get busy.
Start the fuel pump, inject fuel, turn on the circuit, and then ignite!
"Buzz, buzz." Black smoke came out of the exhaust pipe. With a roar, a 2000 horsepower star air-cooled engine started.
One, two, when all 26 engines were started, the roar rang through the whole lake. The birds in the distance were disturbed by this sound. They flapped their wings and flew away from the lake. While flying, they turned their heads and looked at the giant. What is it? It's terrible?
"Mr. President, our aircraft carrier will start soon." Jeffrey said triumphantly to Roosevelt.
The carrier is about to start!
After all the engines were started, it took one minute to run at low speed. After checking that the engine worked well, the operator pushed all the throttle levers of the engine to full speed.
In an instant, the roar of the engine is even greater. The high-speed engine drives the rear propeller to rotate through the reducer. The propeller is immersed in the water. At this time, it is rotating violently and constantly stirring the sea water. You can see that a stream of water is formed around the aircraft carrier.
26 engines and 26 propellers form 26 water flows backward on both sides of the aircraft carrier, and the aircraft carrier will be impacted by the forward impact of this water flow and move forward.
Jeffrey looked at the aircraft carrier with expectant eyes. The time passed second by second. Soon, the hope on his face turned into doubt and strange.
The carrier remained motionless.
How is this possible?
Even if the power is small, as long as it works continuously, the aircraft carrier can still move! This is determined by the basic momentum theorem, but now, the aircraft carrier shows no sign of moving at all.
Jeffrey turned and looked at Roosevelt. Roosevelt's face was full of disappointment.
If this aircraft carrier can't move, what's the use? Roosevelt came with hope, but he didn't see the result he wanted.
Can you go to war with this thing?
"Mr. President, please wait a moment. There must be something unexpected." Jeffrey finished and hurried to the ice carrier.
He went to the place where he was parked and looked at the water below. He saw engines driving propellers and trying to stir the lake. Everything was normal, but the ship just didn't move.
What the hell is going on?
At the wharf, even a tugboat can drag a cargo ship much larger than it. This kind of immobility will occur unless the power is less than the resistance.
With this in mind, Jeffrey squatted down, quickly took out the thick information in his briefcase, turned to the power system, took out his pencil and recalculated quickly.
The roar of the engine continued, and the ship still didn't move. In this way, half an hour passed, and the people on the shore were impatient. Jeffrey was behind him with waste manuscript paper and threw more than a dozen pieces. Finally, Jeffrey stood up with a sad face.
"We miscalculated a decimal point." Jeffrey said, "we have miscalculated the underwater area of this aircraft carrier and miscalculated the resistance, so now our power system can't drive the ship."
There are still too few people, and they are all calculated manually, and they are very in a hurry and have not been reviewed. Jeffrey can't believe this happened.
In this era, there is no super large oil tanker. If there are 300000 ton VLCC oil tankers in future generations, it needs 30000 horsepower to meet the needs of minimum speed navigation. If it is 2 million tons, it needs at least 200000 horsepower. Now, each engine has only 2000 horsepower, and the power of 26 engines is seriously insufficient. At least 100 engines are needed!
Please report us if you find any errors so we can fix it asap!
