P.S.
When I said this in an earlier post ......"You might also install a valve on the the sub that would sense
the difference in air pressure within the boat and without, that would
automatically open to release air from the hull if
you accended using only your dive planes so the hull would never over pressurize
more than the outside water
pressure.
What I really meant to say was...."You might also
install a valve on the the sub that would sense the difference in air pressure
within the boat and without, that would
automatically open to release air from the hull TO
PRESSURIZE THE BALLAST TANKS if you accended using only your dive planes so the
hull would never over pressurize more than the
outside water pressure."
Sorry for that omission by me in that post. It may have caused some
confusion. I never meant to release air from the sub, just use it to pressurized
the ballast tanks and force the water out while keeping all the air.
