![]() ![]() This is done in order to reduce the hydrodynamic drag when the submarine is in water. ![]() The port and starboard movement is controlled by tail rudder.Īlmost all the submarines are cigar-shaped. On reaching the crusing depth, the hydroplanes are leveled and thus the submarine can travel parallel to the water level. This means that a balance of air and water is maintained inside the tanks in order to equalize the buoyant force of the submarine and the water surrounding it. Once underwater, the desired crusing depth is maintained by neutralizing the bouyance force. The wings are so arranged that the water moves over the stern area, pushing it upwards and thus alligning the submarine in a downward angle. Hydroplanes, small movable wings at the stern helps to adjust the angle of dive. Also the air from the ballast tanks is pushed out with the help of pumps. When the submarine submerges in the water, a continuous supply of compressed air is supplied in order to support life inside it. In order to submerge, the ballast tanks are filled with water, making the overall density of the ship higher than the surrounding water. When the submarine is at the surface, its ballast tanks are filled with air, thus increasing making its density less than that of the surrounding water. Submarines can easily control their buoyancy. For this purpose, ballast tanks are used. This can be done by increasing the weight of the ship or by reducing the amount of water displaced. But in order to submerge a ship hydrostatically, a negative buoyant force needs to be generated. A normal surface ship sails on water by creating a positive buoyant force, by displacing more water than its weight. Today they are used for marine sciences research, underwater oil and minerals exploration, salvaging and surveying purposes, underwater cable repairs and also for tourism purpose.Ī submarine also works on the same principle as that used by other ships, i.e Archimedes Principle of buoyancy. Nowadays the use of submarines have proliferated across many fields. Submarines were used for protecting aircraft carriers, for blockade running, for patrolling a country’s boundaries etc. They were extensively used in world war- I & II. Submarines were introduced with the sole purpose of fighting wars. Learn about these interesting and technically complex machines in the article below. A submarine does not fall strictly in the category of types of ships but is certainly an underwater ship. How a submarine dives and surfaces in the water? How it maintains a healthy environment and from where does it gets its power. In this article we won’t be focusing on the utility aspect but on the technical ones. It not only allows the privilege of sailing in a concealing manner but also creates an environment to stay below the water for months together. Everyone knows that a submarine is nothing but a ship floating underwater. No doubt the submarines were introduced with the warfare purpose, there is definitely more to this technological masterpiece. The word submarine resounds the pictures of wars and underwater invasions. ![]()
