![]() Once they're submerged deep down in the water, a computerized system will continuously clear and monitor the air, hence people on board can breath clear oxygen.Īs humans, we inhale oxygen and exhale carbon dioxide off of our body. Both of them function to bring in the air. ![]() And when it's submerged at periscope depth, they also have a snorkel mast. When in port, submarines have access hatches. Sometimes, you may wonder how come people on submarines can breathe while they are in that closed space. In short, the longer they receive echoes, the further the distance is, and vice versa. Once the waves bounce off the objects, they will receive reflected echoes which can determine the distance between the objects. It works like radar – sending out waves into the sea to identify nearby objects, targets, underwater terrains, and other threatening things. They use ocean GPS satellite navigation, which relies on the space satellites to locate their position.Īnother system that they use is called sonar, which stands for sound, navigation, and ranging. Thankfully, all submarines are equipped with navigation that guides them through computers. Oftentimes, the pilots are even clueless on where they're going to, since it's impossible to see when it's getting deeper. And that's also the same with people boarding the submarine. If you ever have snorkeled or took a diving under the water, you will know how dark it is when you look around your surroundings. Therefore, as the air on the ballast tanks is released, the tanks will fill in the seawater.Īs a result, the subs will be heavier and more dense, making them submerge into the deep water. However, the key point for submarines to successfully dive is actually located on its huge tanks, named ballast tanks.Īt the top of the ballast tanks, there are valves that will open up when the subs are about to dive. Taking the same principle, that's also how submarines work. And apparently, the water adds the weight of the cup, causing it easier to sink. The reason is because when you put pressure on the cup, it will be filled with water. Then, you push the cup down to the bottom of the bowl. Imagine you're having a big bowl of water and a cup. They also make use of Very Low Frequency (VLF) radio when travels under the water, capable to reach the depths of 60 feet. That's why they have this equipment, designed specifically to contact directly or through a satellite. ![]() While they operate the subs, they should continuously keep in touch with shore bases and ships. The Chief of the Watch: operates the Ballast Control Panel (BCP) to control the ballasts and maintain the buoyancy. The diving officer: supervises every move and actionģ. The helmsman & planesman: steers left, right, up, and down the controls to adjust the rudder and diving planesĢ. It takes several people to drive the submarines on the surface or when they're submerged. Of course, submarines don't run by themselves. Generally, submarines can dive deeper than 800 feet, and although they can stay under the water for long periods, they only limit the duration for 3 months due to the food and supplies stock they bring with. Normally, they can also be used to recover lost items when a ship sinks, and even as a tourist ride to look for exotic view of the deep water. However, the use of subs are not only limited for those things above. It was originally created as military machines, but there are a few smaller ones used for scientific research purposes. super big) ship that is able to dive deep into the water. Read on! What is a submarine? Photo: Futurity In this post, we will break down everything you need to know about the submarines and how they can submerge, navigate, and float back into the surface. Who doesn't know submarines? Their gigantic size and wide-ranged of purposes probably have left you in awe, but have you ever wondered how they actually work?
