5 Ways Submarines Work

Introduction to Submarines

Submarines are complex machines that have been used for centuries, with the first successful submarine being invented by Cornelius Drebbel in 1620. Since then, submarines have evolved to become sophisticated vessels used for various purposes, including military operations, scientific research, and exploration. The way submarines work is a fascinating topic, and in this article, we will delve into the details of their operation.

Ballast Tanks and Buoyancy

Submarines have the ability to dive and resurface, which is made possible by the use of ballast tanks. These tanks are filled with water or air, depending on whether the submarine needs to sink or float. When a submarine wants to dive, it fills its ballast tanks with water, which increases its weight and causes it to sink. Conversely, when it wants to resurface, it fills the tanks with air, which reduces its weight and allows it to float. This process is crucial for the submarine’s ability to control its buoyancy and navigate through the water.

Propulsion Systems

Submarines use various propulsion systems to move through the water. The most common type of propulsion system used in submarines is the diesel-electric propulsion system. This system uses diesel engines to generate electricity, which is then used to power electric motors that turn the submarine’s propeller. Other types of propulsion systems used in submarines include nuclear reactors and air-independent propulsion systems.

Steering and Control

Submarines use a variety of steering and control systems to navigate through the water. The most common type of steering system used in submarines is the rudder, which is a flat surface located at the back of the submarine that is used to control its direction. Submarines also use planes, which are flat surfaces located on the sides of the submarine that are used to control its depth. The submarine’s control system is typically operated by a helmsman who uses a control yoke to control the submarine’s movements.

Sensors and Communication Systems

Submarines use a variety of sensors and communication systems to navigate and communicate with other vessels. The most common type of sensor used in submarines is the sonar system, which uses sound waves to detect and track objects in the water. Submarines also use radar systems to detect and track objects on the surface of the water. The submarine’s communication system typically includes a satellite communication system that allows it to communicate with other vessels and shore-based stations.

Life Support Systems

Submarines have life support systems that provide the crew with a safe and healthy environment. The most common type of life support system used in submarines is the air recycling system, which removes carbon dioxide and other impurities from the air and replaces them with oxygen. Submarines also use water purification systems to provide the crew with clean drinking water. The submarine’s life support system is critical for the crew’s survival, especially during long-duration missions.

🚨 Note: Submarines are complex machines that require careful maintenance and operation to ensure the safety of the crew and the success of the mission.

In summary, submarines are sophisticated vessels that use a variety of systems to operate, including ballast tanks, propulsion systems, steering and control systems, sensors and communication systems, and life support systems. Understanding how these systems work is crucial for appreciating the complexity and sophistication of submarines.
