nice find deltaboy that is pretty cool, i would have never even thought about typing supercavitation in the search bar and looking for, so i never would have known about had you not posted it,

Who cares if its been posted or not you cant do a search on every single thing you come across,

now i could understadn Blue Cell's point of view had you you started a US VS China thread, but i dont think there is many threads on Supercavitation,

Good Find

has there been any testing or any stats like if the US will produce any of subs with this tech

Would this not make it far too easy to pick up? I mean that much water being pushed apart must make it easy as all hell to spot. :|

the whole point would be to move away from the run silent run deep mentality, yes it would make a noise but does it matter if you can do hundreds of miles an hour. Unfortunatly supercavitation as applied to submarines is a good while off yet, though most major navies around the world are looking into it (including the us, uk, france, russia, india and probably china). Supercavitation has been known for quite a while but the western countries used it to design supercavitating propellers and didnt think to apply it to cylindical bodies (we left that to the russians)

Deepangel for the timebeing remains purely sci-fi

Theoretical question on super cavitation.

In this phenomonon...bubbles/cavitation on the hull would tend to follow the hull back ..giving isolation on the shape..from the surrounding water..hence speed...reducing wet surface area/friction.
What I am curious about is would the bubbles tend to follow the hull all the way down...to the stern...until they pass off the hull???
If you get this post..I thank you in advance for your opinion.

what I am getting at..is at the stern where the hull tapers...would the supercavitation tend to follow the widest portion of the hull or taper to follow the contours of the stern. I hope this makes sense to you .

Thanks,

it depends on the shape of the cavity and the object in the cavity. Generally the pressure of the surrounding water tries to collapse the cavity and this keeps the cavity close to the surface of the object till after it passes. I have some high speed camera pictures of the US supersonic tests but they are in .pdf format and i have to figure out a way to put them on the net for you guys (there may even be a copyright issue too).

Thanks for that view. It is about what I figured but not the reasons you stated...though your explaination made good sense. I appreciate your input.

Thanks,
Orangetom

i could show you, if i could figure out how to get these pics uploaded.
