An underwater vehicle surrounded by an enveloppe of gas or air in a
supercavitation scheme or else is still under water pressure. in deep water
water pressure on the hull would be the same than if the water was directly in
contact with the hull. What keeps the water off the hull exerts the same
pressure on the hull.

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.
