Dear readers, today I will write about submarines which many of us do not know. To begin with, a submarine is a warship that sits under water and can attack and repulse an enemy in any difficult situation. It can work completely underwater in the dark where there is no light or air, just water and water.
Now we will know what a submarine is:
First Invention of Submarine:
In 1620, a Dutch engineer named Cornelius Van Drebbel invented the underwater submarine. He is called the father of the submarine. Many will be surprised to hear that the submarine was invented almost 100 years before the discovery of America. He served in the Dutch Navy and the first submarine built was made of wood and covered with leather to prevent water from entering the submarine.
History of submarines:
Since the discovery of the first submarine, people's interest in submarines continues to grow and various countries are encouraged to build submarines. When they saw that those with submarines had a greater advantage in battle, new forms of submarines were invented in the eighteenth and nineteenth centuries. In 1880, the first steam powered submarine was invented, followed by diesel gasoline and electric powered submarines. Especially in World War I and World War II, submarines were widely used. The more submarines they had, the more they had the advantage in the war and the more submarines they had, the more submarines they could win in the end. In 1950, the first nuclear submarine was invented. Discovery This will be discussed in the next part. At present, many countries of the world including America, England, France, Japan, and China have many types of sophisticated submarines that have been added to their navies for various tasks.
Types of submarines: There are many types of submarines in modern times. Some types of submarines are discussed below
1. Diesel powered submarines.
2. Nuclear Submarine
3. Ballistic Missile
4. Special Mission Submarine
5.Cruise Missile Submarine
6.Midget Submarine Submarine
How Submarines Work:
To know how submarines work, first of all we need to know the type of fuel in submarines. We already know that submarines use 2 types of fuel, diesel and nuclear.
We will now discuss diesel powered submarines: Diesel powered submarine generators generate power and react with the generator to turn the propeller at the back of the submarine and the reaction proceeds as it goes forward.
The charge completes all the functions of the submarine including oxygen. This is basically how diesel powered submarines work.
Nuclear Submarines Work: Nuclear submarines are powered by nuclear fusion to turn turbines. The power generated turns the rear propeller and thus nuclear submarines operate. Nuclear submarines are much more powerful than diesel powered submarines and can travel at a much faster speed and do not have to repeatedly come out of the water to refuel. The nuclear fuel that is given during production is enough to be given once but diesel powered submarines have to rise from the water as soon as the diesel runs out, that's why nuclear submarines are very popular among all countries.
Living on a submarine is very difficult and requires a lot of discipline and teamwork. Submarines are designed to operate for extended periods underwater, meaning that crew members must be prepared to live and work in confined spaces for weeks or even months at a time. 'one time. A submarine has a sleeping area called a docking station. Submarines have docks where sailors can take their meals. The ship's cooks usually cook and serve it in the dining room. Due to the limited space on board, crew members eat during shifts. Submarines have a lot of water and sewage storage, so crew members need to be careful about their water usage and personal hygiene. They have access to showers and toilets, but they must take into account the preservation of property. Submarines have little room for entertainment. They can also watch movies or play games during their free time.
