The biggest advantage of nuclear power is to provide almost unlimited endurance. The energy contained in atoms is released through fission. The heat generated is like a boiler, which is used to heat water, turn it into steam, and push the steam turbine to do work, so it can output energy.
The propeller at the tail can be driven directly through the reducer to make the submarine move forward. At the same time, it can also drive the generator to supply power to the whole submarine.
This is the main principle of the nuclear powered submarine. At the same time, one of the big problems in the long underwater endurance is oxygen. For the nuclear submarine, it is made by electrolyzing water. Anyway, the source of power is infinite. At the same time, the fresh water inside the nuclear submarine is also obtained from seawater desalination.
In this way, except for the food that needs to be prepared at the time of departure, everything else can be prepared at any time to meet the navigation requirements of the submarine to the greatest extent. How long you can sail underwater depends entirely on the self-supporting ability of the crew inside the submarine.
Like now.
The underwater world is quiet. Only the steam turbine and main reducer in the engine room at the tail make a slight low rumble. The whole submarine is like a quiet shark.
On the command tower, Captain Otto krezimmer was listening carefully to his subordinates' report.
"Captain, according to our route, we have crossed the Arctic ice sheet and the Chukchi Sea is in front." Said the vice captain.
Otto was the number one trump captain of the German submarine and had brilliant achievements again and again. Therefore, he was finally appointed as the captain of the first nuclear submarine u-801.
This number spans many numbers. It starts directly from U8. Later nuclear submarines will also increase backward in turn. In German shipyards, the number has been listed as u811
After a long sea trial, the submarine has met the design requirements and even surpassed in some aspects. And the crew have also undergone strict training.
Even Otto has studied for half a year before he graduated from the newly opened major of nuclear submarine command and obtained the job certificate of nuclear submarine captain.
He has been familiar with all the structures of nuclear submarines and some risks contained in nuclear reactors. For him, everything is aimed at victory!
"We have created a miracle. We are the first submarine to cross the Arctic!" "Now, the submarine floats up and is ready for starlight navigation," Otto said
"Yes, ready to float." The vice captain followed excitedly and gave orders.
They sailed underwater for half a month. If they were diesel electric submarines, it would be unbearable. The noise of the diesel engine, the smell of diesel oil in the air, the feeling of moisture and the smell of sweat will make people feel nauseous.
But now it's different.
Their submarine has always been very quiet. The oxygen produced by electrolysis even has a fresh taste. It is a small amount of ozone. The air inside the submarine is still good.
Of course, if they can float up, they will still make people feel happy. They haven't had the sea breeze for a long time.
"The sonar room reported that there was no sound of ships nearby."
"The ballast tank is drained and ready to float."
Under the ice, they have always sailed at a depth of about 50 meters. Now, with the issuance of orders, the submarine with a displacement of 6000 tons has slowly floated up from the water.
The bow first came out of the water. When its drop like bow was exposed, it seemed like a huge whale floating out of the sea, and then the back hull.
"Open the hatch cover." Otto said and climbed up the ladder.
In the past, the XXI submarine was only 2000 tons, but now the nuclear submarine has been enlarged to 6000 tons, greatly improving the space of the whole submarine.
There was plenty of space on the command tower, and Otto, wearing an army coat, could climb up easily.
Now, it's night. There are stars all over the head. The cold wind is blowing, which makes people feel the cold wind to the bone, but it's still very exciting to smell the fresh air.
I saw the outside world for the first time since I set sail.
Following him, the first mate of the boat also came out, picked up the starlight navigation equipment in his hand, aimed at the familiar constellation, and prepared for the first calibration.
The navigation and positioning of submarines are also very important. In previous submarines, this contradiction is not prominent, because submarines navigate on the surface most of the time. How surface ships navigate, submarines navigate.
However, after the invention of the vent pipe, submarines often navigate underwater. At this time, there is a way to navigate. Now, nuclear submarines navigate completely underwater and can't see everything on the water, so its navigation is more critical.
To this end, submarine designers took the inertial navigation equipment used in the missile.
The core of the inertial navigation system is the gyro, which is stable. Through the measurement of relative position, we can know the acceleration of the submarine. Then, as long as the acceleration is integrated once, we can get the speed, and the range is obtained through the secondary integration. Compared with the position at the time of departure, we can then calculate the longitude, latitude, vertical and horizontal roll angle, speed Navigation parameters such as sailing distance and heading.
However, this thing is not very sensitive. Before the invention of laser gyro, the error of mechanical gyro will continue to increase due to friction.
In this way, it is necessary to calibrate after sailing for a period of time.
Starlight navigation is the most common way of navigation. It can be said that it has been used by navigators since Columbus, which is something every sailor should learn.
Now, the chief mate carefully proofread it three times, and finally, with helplessness on his face: "Captain, after more than half a month of navigation, our course has made great errors. Now, we are not sailing in the direction of Chukchi Sea. What we will encounter in front of us is not Langer Island. Our course has deviated by 30 degrees, We are sailing in the direction of Novosibirsk island. "
Inertial navigation system, the longer the time, the greater the error. In the past, the trial time was not long enough, but now, accumulated, there was a huge error!
Otto was prepared for all this.
"OK, let's adjust the course and sail East!" Otto said, "keep on high alert. The crew are in groups of two. Come up and let out the air for two minutes in each group."
At present, it is still far from the Soviet coastline, and the Soviets do not have anti submarine forces to operate here. At night, navigation should be safe.
I've been holding it for more than half a month. It's time for the sailors to come up and have a look.
Otto's order almost made the sailors shout long live. They were arranged inside the submarine in order, ready to go up and let out the wind.
"Turn on the sea search radar and raise the vigilance of the sonar room."
Please report us if you find any errors so we can fix it asap!
