Journey to the Deep: How Submarines Submerge and Navigate Underwater

A submarine is a specialized underwater vessel designed for military, scientific, or commercial purposes. Submarines are unique vessels that can operate underwater for extended periods, thanks to their advanced technology and engineering. In this article, we will discuss how submarines submerge, navigate, and steer underwater.

 

Submarine Submergence:

Submarines are designed to operate both on the surface of the water and underwater. When a submarine wants to submerge, it fills ballast tanks with water. This process causes the submarine to become heavier, and it starts to sink. The ballast tanks are located at the bottom of the submarine and can be filled or emptied using pumps.

 

When the submarine is submerged, it needs to maintain a constant depth underwater. This is achieved by adjusting the amount of water in the ballast tanks. If the submarine needs to surface, it will expel the water from the ballast tanks and use its engines to propel itself to the surface.

The Principles of Submarine Navigation:

Submarines use a combination of instruments to navigate and steer underwater. The most important instrument is the sonar system, which uses sound waves to detect other vessels, objects, and the sea floor. The sonar system can detect objects at long distances, making it essential for submarines to avoid collisions and navigate safely underwater.

 

Submarines also use GPS (Global Positioning System) and inertial navigation systems to determine their location and track their movements. The inertial navigation system uses accelerometers and gyroscopes to detect changes in the submarine's direction, speed, and position. It can also compensate for the movement of the water around the submarine, which can affect its course.

 

The submarine's periscope is another important instrument used for navigation and surveillance. The periscope is a retractable tube that rises above the waterline and allows the crew to see above the water. The periscope can also be used to observe other vessels, the coastline, and to locate targets.

Principles of Submarine Steering:

Submarines are steered by controlling the direction and speed of their propellers. The propellers are driven by electric motors or diesel engines and are located at the stern of the submarine. The submarine's rudder is located behind the propellers and is used to control the direction of the vessel. When the rudder is turned, the water flowing past the propellers is redirected, which changes the direction of the submarine.

 

Submarines can also use hydroplanes to steer underwater. Hydroplanes are small wings located on the sides of the submarine, and they can be angled to change the direction of the vessel. Hydroplanes work by altering the amount of water flowing over them, which creates a force that pushes the submarine in a particular direction.

 

In addition to the propellers, rudder, and hydroplanes, submarines also use the ballast tanks to control their buoyancy and maneuverability. By adjusting the amount of water in the ballast tanks, the submarine can control its depth underwater. If the submarine needs to turn, it can adjust the water in the ballast tanks on one side of the vessel, which creates a force that turns the submarine.

Conclusion:

Submarines are highly advanced vessels that require specialized training, skill, and technology to operate safely and effectively. The principles of submarine submergence, navigation, and steering are complex and require precise control and monitoring to ensure the safety of the crew and the vessel. The sonar system, GPS, inertial navigation system, and periscope are essential instruments used for navigation, while the propellers, rudder, hydroplanes, and ballast tanks are used for steering and maneuverability.
