What makes the most noise in a submarine?
I was reading the article in the news feed about the Chinese supposedly testing an MHD propulsion system and a question entered my mind that I though I'd put forward to you gents.
Obviously some details are probably classified, and this probably differs from sub type and class and speed and depth. However I'm curious just how much of a modern nuclear submarine's radiated noise signature is produced by the screw pump jet, and other assorted drive components that directly propel the submarine. By comparison how much noise is produced by the machinery like pumps, hydraulics, electric generators, steam noises from the reactor Ect. How much is created by other factors like flow noise, and crew. Thanks |

Shoot. Knew I should have joined the navy. But then again Canada doesn't have much of a Navy to join XD

Especially when its you who's about to get wrapped in it. :o |
Some interesting (and technical) info here:

This thread made me remember a documentary about modern subs.
In this program a person(can't remember his title) said each time we have erased a noise problem in a sub a new one pops-up. When he said those words I came to think of a saying- A chain isn't stronger than its weakest part. Translate this into the world of Subs - A sub isn't more silence than its noisiest part. Markus |
If you remember the name of the documentary, please let us know. I don't recall seeing the one that you described.
