Question
James,
Somewhere in this thread, someone (you?)
wondered if a sub wrapped in a supercavitation bubble might be able to
operate at great depth without regard for pressure hull strength
considerations. I suppose in theory that's possible, depending on
whether or not one could generate a bubble of greater pressure than
would be encountered down deep. However, I don't think it would be
wise to rely on such a system, though; for the obvious reasons of what would
happen if it failed at greater than design collapse depth.
Whammo! Your barracuda becomes a flounder!

Oh I definitely understand that, I don't
imagine that anyone would want to travel that fast near anything that
would come even remotely close to the sub. I was just wondering if
the assumption that supercaviation = less hull pressure was
accurate.

Hi speed for underwater vehicles is
suitable only with enough deep waters and "room" around, there is no way
you can drive a mini sub at more than 10 m/h in shallow waters or with
reefs and obstacle. it s like driving a car in the fog. Even with
100 Ft visibility once you SEE the obstacle the collision
is at 5 seconds, 5 sec to make a sharp turn or stop is
actually not easy at all. Add to that the momemtum of the
sub.
