I forgot to mention. If you have the room
for a diver lockout CHAMBER, you also have a built in flood/scuttle
valve. If you left the diver lockout chamber door open to the hull and flooded
the chamber, you flood the hull.
The above is assuming you DON'T have a chamber
door safety switch which made sure the chamber door was fully
closed and latched before the flood valve could
work, or you disable said switch.
You can also make a small 1 atmosphere sub have a
diver lockout (without a chamber) by pressurizing the interior to equal the
outside pressure and opening a lower hatch to escape as in an ambient sub.
Therebye changing your small 1 atmosphere sub into
an ambient sub for either diveing purposes or escape.
If you used this for diving purposes you could
reenter the sub, close the lower hatch, then let off interior air pressure and
change it back to a 1 atmosphere sub.
Small size interior space does not necessarily
preclude a diver lockout. Just become ambient.
I wonder if anyone has built a 1 atmosphere sub
that converted to ambient and back again? The neat thing for diving with
it would be you could start offgassing the nitrogen from your body as soon as
you converted the sub to 1 atmosphere again
so you could stay underwater in the 1 atmosphere
sub and offgas, then convert the sub to ambient and go out again. I wonder how
hard it would be to install an internal bottom hatch on the Kitteridge 350
and pressurize it to ambient and back to 1 atmosphere again?
Just more alternatives. I like this
forum as a sounding board for raw sub ideas that we can tweak into workable
ones. Some sub ideas might need refinement, more discussion, or wise
deletion, but none are stupid.
Kindest Regards,
