[PSUBS-MAILIST] Ambient bailing without flooding.

Hi Joe and Myles.
Here are some links to Kent Markham's silent
runner II ambient half dry sub.
I bought my minnkota from Kent and along with
the motor he sent me a set of plans for both his
silent runner 2 and his delta wing ambient
subs.Both plans available at psubs too.
You can see the lower side door on the photos
where the diver gets in and out.
So you can see how the air bubble in the canopy
could keep from getting
flooded but the operator could still exit the
sub if he could not surface for some
reason, then come back to retrieve the sub
without the interior getting wet.
In the silent runner 2 it would not matter if
the interior got wet, but I am just
showing you this to explain the principle of
how the interior could stay dry in
the ambient designs you both are contemplating
and you still could bail without
flooding the interior. Think of an upside down
glass being pushed underwater.
As you go deeper the water wants to rise higher
in the glass but you keep it from
rising by putting more air pressure into the
glass. Then if you need to bail you can
swim out the bottom of the glass without having
to flood the glass itself. That way
you would not flood your engine or motors or
anything else in the interior you did not
want to get wet. Just no sense in flooding the
ambient. Just make sure you design an
exit hole in the bottom when you build it and
swim out your gopher hole if necessary.
Bill.
