I agree with you and the others. I wanted to learn about this subject, and multiple recent videos that I watched before this (all about "how submarines work") were longer yet didn't even touch on how a submarine dives and surfaces...their main capability.

I wish people still spoke and presented with a Transatlantic accent like this.

Or some will call it the Mid-Atlantic accent. It's a cross between British and American. I liked it too. I wish we still spoke like this.

After already having watched multiple recent videos about "How Submarines Work", I've learned about the crew quarters, missiles they have, and what China is working on, but not "how submarines work", namely the ballast tanks. Thankfully, a video from 1955 fit the bill and I could finally get a good idea. I'd still like to learn more about the pressurized air (like if they create oxygen through electrolysis, etc), but I do have to say that this is the best video I've found so far on the matter.

The air tanks to pressurize the ballasts are filled when the sub is surfaced. The compressed air is then stored and ready to use when needed to resurface. I imagine they also have reserve tanks of compressed air that aren't ever used unless the main tank fails in some way.

This is amazing to me, to watch something I know that many others watched during their training, many of whom are gone now, may they be at peace.

Just FYI, the sub at the end is the USS Tusk (SS-426), built during WWII but Commissioned in 1946.

So well explained

Thanks for posting this, I still have questions so the search continues. 👍🏼👍🏼

Glad you found this one helpful! I don't have any more videos like this one, but if you look in the video description I linked the original source of the video (I just added subtitles for a student with an auditory impairment). The original source may have more videos like this one.

Good information. While sinking where the "vent air" is stored? Thanks.

So I guess they need to go up for air periodically to avoid running out of pressurized air needed to surface?

@stevenlarratt3638

If you imagine the submarine is neutrally bouyant so a small amount of air will expand as the sub rises. As it does the air can be re pressurised back into the system, this only looses a small amount or air. Imagine a tank the size of a firemans cylinder can provide useage for 45 mins at 300 bar, similar story here, as it gets used there is a small drop off in total pressure but years of usages. only after an emergency blow will you need to resurface.

So compressed air isn't as buoyant as normal air? It's the same amount of air in the sub at all times, it's just compressed into the system when flooding the tanks right? I'm lost

@mattlamb34

Жыл бұрын

Correct. It’s all about volume and weight. You can have the same quantity (mass/mole) of air but depending on how compressed it is, it will take up a smaller volume. The relationship is - Volume = Pressure/((A Constant) x Temperature) By displacing the volume of water in the tanks with air you reduce the weight which makes the submarine float and vice versa.

where do they get that high pressure air from?

When water is entering the ballast tanks air is being drawn out of the ballast tanks. Pumps will pull the air from the ballast tanks and push it away through external holes in the submarine's hull which will leave empty space in the hull, that space will then be filled with seawater through the bottom holes you can see in the video.

Does carrying pressurised air tank effects the buoyancy of the sub? Etc-air is less dense than water, more air mean more floating force?

if the air is pressurized in tanks then it won't be less dense than water anymore. For example the air tanks that a scuba diver uses sink.

It seems pretty simple you would need some sort of container that when you suck in the water it fills the container and when you push out the water it empties the container so i am thinking some sort of pump but the question would be how you would interface this pump also you would probably have to have some sort of sensors that tell you the desired water level is reach so you don't over suck the water.

Real submarines not narco imitations that superficially imitate submarines. Ballast tanks are big.
