The Third Reich - Chapter 1704

“If you want to push such a big guy, you have to have a very powerful power system?” Roosevelt got into his wheelchair and continued to look at the two-million-ton aircraft carrier and said to Jeffrey.

Although I am a layman, I can definitely see that the motivation for this is astronomical.

Hearing Roosevelt’s words, Jeffrey seemed to be showing off his knowledge and explained to Roosevelt: “The power system required depends on the design index we give to the ship. Because the ship is sailing at high speed, the resistance and speed It is a cubic relationship. For example, if our battleship is designed to have a speed of 30 knots and requires 200,000 horsepower, then the speed will reach 35 knots, and the required power will reach a terrible 400,000 horsepower.”

This is the terrible third power, and if the speed is higher, it will become the fourth power, which is even more abnormal.

Another meaning of this sentence is that if the design speed is reduced, the required power system can be greatly reduced. In later generations, the power system of hundreds of thousands of tons of oil tankers, and the power system of several thousand tons of frigates are almost Almost, not afraid of slowness, as long as you can move, the big deal is to spend a few more days at sea, and not in a hurry.

The navy is not too lofty. If you give such a big guy a speed that matches the fleet, it will definitely not be created. Now, it only needs a speed of ten knots, and it is no problem after its own calculation.

Hearing what Jeffrey said, Roosevelt said: “In other words, our super aircraft carrier will be as slow as a snail?”

This analogy embarrassed the people present. Jeffrey hurried over to round the scene: “President, snails don’t seem to crawl in the sea, right? It’s better than sea turtles. Don’t look at sea turtles slow on land, but in water. , Is also quite agile.”

With that said, Jeffrey made a turtle swimming.

Roosevelt laughed, and everyone else laughed. Amidst the laughter, Jeffrey gave the order for the sea trial.

If it’s an ordinary ship, you can let the leaders of these countries get on the ship and go out with the ship for sea trials. However, this ice carrier is the first time in history, and no one can guarantee how reliable this ship is. What if you go out and break when you run, throw Roosevelt and others into the water?

Therefore, Roosevelt did not propose to go up, nor did other people. We were on the land together, watching the actions of this behemoth.

“Start the engine.” Jeffrey shouted loudly. At this time, the ship had not connected the radio, or even the superstructure. There was only one hull. Therefore, Jeffrey could only shout into a loudspeaker.

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

Start the fuel pump, inject fuel, connect the circuit, and then ignite!

“Buzz, buzz.” A puff of black smoke emerged from the exhaust pipe, and a 2,000-horsepower star-shaped air-cooled engine was started with a loud roar.

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

“Mr. President, our aircraft carrier will be launched soon.” Jeffrey said to Roosevelt triumphantly.

The aircraft carrier is about to start!

After the engine was fully started, it took one minute to run at low speed. After verifying that the engine was working well, the operator pushed all the engine throttle levers to full speed.

In an instant, the roar of the engine became even greater. The high-speed engine drove the propeller behind to rotate through the reducer. The propeller was immersed in the water. At this time, it was spinning vigorously and continuously stirred the seawater. I saw a stream of water forming around the aircraft carrier.

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

Jeffrey looked at the aircraft carrier with expectant eyes. Time passed by every second. Soon, the hope on his face turned into doubt and strange.

The aircraft carrier did not move.

how can that be?

Even if the power is small, as long as it continues to work, the aircraft carrier can still move! This is determined 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. At this time, Roosevelt’s face was also full of disappointment.

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

Can this thing be on the battlefield?

“Mr. President~www.mtlnovel.com~ Please wait a moment, there must be something unexpected.” Jeffrey finished speaking and hurried to the ice carrier.

He took three steps and took two steps, and ran to the docking place in one breath. He looked at the water flow below. He saw a set of engines driving the propellers, stirring the lake water vigorously. Everything was normal, but the boats Just not move.

what is the problem?

At the wharf, even a tugboat can drag a cargo ship much larger than it. Unless the power is less than the resistance, this kind of immobility will occur.

Thinking of this, Jeffrey squatted down, quickly took out the thick materials in his briefcase, turned to the power system, and then took out his pencil to quickly recalculate.

The roar of the engine continued, and the ship remained motionless. In this way, half an hour passed, the people on the shore were already impatient, and behind Jeffrey was scrap paper, and also threw a dozen sheets. In the end, Jeffrey stood up with a crying face.

“We miscalculated a decimal point.” Jeffrey said: “We miscalculated the underwater area of ​​the aircraft carrier and calculated the resistance wrong. Therefore, our power system cannot drive the ship now.”

There are still too few manpower, and all manual calculations are performed, and the construction period is very short, and Jeffrey can’t believe that this happened without a review.

In this era, there is no super large tanker. If it is a later generation, with a 300,000-ton tanker, it will need 30,000 horsepower to meet the needs of the lowest speed. If it is 2 million tons, it will need at least 200,000 horsepower. Horsepower is good. At present, each engine has only 2000 horsepower. The power of 26 units is also seriously insufficient. At least 100 units are needed! 8) For more wonderful novels, welcome to visit everyone’s reading academy
