My German Empire

I heard the news that they had arrived in pole, the submarines sounded the cheers of the sky.

If it is a war, the inside of the submarine is strictly forbidden to have extra movement, so as not to recruit the disaster of killing. However, the location they now is the pole pole, even if there is no more moving and quiet, some people will come to them.

The proposal road of the big weapon of the big love. "The boat is long, is we doing any ceremony? Is it like equatorial ritual."

The equatorial ritual is a certain ancient naval tradition continued from the big airborne era, and there is a text recorded to be traced back to 18-19 centuries, also known as "Equator Festival." When the ship passes the equator, except for the value, all the seafarers have holiday a day, put the wine banquet, use the whole pig, the whole sheep, the sea. Some captains also have a sildanity in the driving table, and the seafarers danced while drinking, praying for the blessings of the sea, bless peace.

Later, this kind of custom spread to the Navy, but the "Equatorial Ceremony" in the Navy is to make the new sailor to ensure that the new sailor can bear the new sailor by setting up a "April Fool's Day". The suffering days of the sea.

For example, when the US warship passes the equator, the old sailor will rise in the warship with a "pirate flag", and announced that the warship is taken over by the sea gods and his followers. Old sailors will wear Shanghai to theft to "rectify" new soldiers, starting from morning, new soldiers will put on travel shoes, shorts and white clothes, queue into the gothel, waiting for veterans to pack. After all levels have been finished, the sectors dressed up by the crew, and a certificate of a SHELLBACK is issued for the recruits.

It's just that they are now driving under the iceberg, and it is impossible to breathe. I want to think about it. "The ceremony is even if it is, give each person with a black beer at noon."

The boat once again broke out a cheer.

***********************************

After a very pole, sailing seven days and seven nights, and the voice was loudly. "The boat is long, we have passed through the ice!"

"The upper float!" The boat grew up and told.

They sailed more than half a month in the water, they were so crazy.

Although the working / living environment on nuclear submarines is more superior to conventional submarines, such as nuclear submarine engine noise is much smaller than diesel engine. There is no pungent diesel in the air; the electrolytic oxygen produces a small amount of ozone, and the ozone taste is like the dust and wild grass heterozygous taste after the rain, but it is also very fresh; plus Cailboats can take a bath regularly, remove the sweat on the body, plus the air purification system and ventilation system in the inside of the submarine, so the air inside the submarine is still nice.

It can be more than half a month in this day and night, and many boat people still have insomnia, loss of appetite, low blood pressure, waist leg pain.

The submarine is generally sailed for dozens of days during the sea, because the submarine is unable to distinguish between day and night, the submarine has begun to be a cycle of 18 hours, which is cut into three in three. For 6 hours, it is used to sleep, duty and leisure, so becoming a boat on the submarine. Applicants should review and evaluate and high-intensity training through a series of brutal tests, but this is better after landing. The hardship of life. Cailboats not only need to have a wealth of technical knowledge, but also need enough determination and perseverance to complete the water for a few months. Ordinary people are basically unable to work in this hard environment.

At the same time, the naval is trying to place entertainment facilities in a limited submarine space, try to reduce the pressure of the soldiers, such as the new nuclear submarines on the later generations, and even a small swimming pool, cinema, fitness venue, etc., Russian military and US military submarines. The sauna relaxed to the soldier. Different colors in the submarine cabin, help boats overcome clamps.

At this time, the German nuclear submarine has not been able to install the swimming pool and cinema,

As the upper floating command, the high-pressure air entered the ballast water tank, after the sea water was emptied, the buoyancy was greater than gravity, and the submarine was quickly flying underwater. Suddenly, the headboat of the submarine is like a dragon, from the sea, and then heavily fell on the sea, splashing countless water.

The nuclear submarine revealed its smooth shape, especially its command tower, almost two of the submarine's boat, which looks quite beautiful. The following is wider, the upper surface is very similar, the appearance of the housing of the podium is very similar to a streamlined cars, which is also to reduce resistance.

A sailor to unscrew the hatch of the ship, the residual sea water is wrapped in a fierce sea breeze, and the people around them are cold. The submarine internal due to power and mechanical equipment, maintained a high temperature above 30 degrees, which is like hot Sahara desert.

"It's so cold!" Everyone hurriedly found the coat to put on, and climbed out of the ladder to the deck. Although it is now the Northern Time, the sun is head, but it can still feel the cold wind. But smelling this fresh air taste, the sailors exaggerate, greedily breathe the air with a seaweight.

The pilot is very satisfied with a six-point calibration.

The six-point meter is an optical instrument that measures the angle between the two goals - most commonly used to measure the angle between the celestial body and the sea (ground) flat or the celestial body and the celestial body. The angle is measured, and then the latitude of the sun direct point is found, the latitude of the observer is located. This is a significant significance for the navigation. Since the 18th century, the six-point instrument has always been an important positioning and navigation tool.

Their nuclear submarine uses the inertial navigation system, the core of this system is the gyro. The gyro is stable. Through the relative position measurement, the gyro can know the submarine's own acceleration, and then, as long as the acceleration can be accepted, it can get the speed, and the second integral is obtained, and the position of the time is compared, it can be Navigation parameters such as the longitude, latitude, longitudinal rocking angle, speed, navigation distance, and navigation of the submarine are calculated.

This is not an advanced technology. In 1852, French physicist Fu Kok created the earliest Four Cologne screw and officially proposed the term "gyro". At the beginning of the 20th century, German explorer Anhz would like to take submarine to Arctic to explore, in 1904, in 1904, the world's first navigation jaro, opened up a road of gyroscopic to indicate a position on the moving object. At the same time, German scientist Shuler created "Schuller Tuning Theory", which became the theoretical basis of the gyroscope and navigation instruments.

Unfortunately, even if there is a subsequent optical instrument, the laser gyroscope and other advanced instruments will have an error, let alone the mechanical rotor gyro-based gyro; over time, the error will continue to accumulate, so every sailing After time, appropriate calibration is performed.

The pilot drums the six-tier in the hands of a while, and reports to the boat. "The boat is long, our head has a deviation, and it is about 20 degrees from the original route."

The toddler of the boat did not think of it, these are their expectations. Just say something, a sailor responsible for the warning shouted. "The boat is long, the iceberg is drifting with us!"

The boat is looking forward to the direction of the sailor. I really saw a slowly flying a iceberg. The iceberg has a truck so much, and those who are familiar with the sea know that the iceberg is just small. Part, mostly hidden under water, the volume ratio of the iceberg water is approximately 1: 9.

"Prepare dive!"
