Hi Dan.
My hybrid design ideas were towards
enabling a person who was going to build an ambient ANYWAY, to enable them to go
a bit deeper.
You wrote...." If you put in safety valves to
release any positive pressure you had in the hull in case you rise too close
to the surface and they release air, you
won't have the air to put in the tanks later on."
You would only have a hull interior overpressurized
situation if you were accending while ONLY using your dive planes to
power
you upwards, because if you were accending other
than using your forward motion and planes, you would be using your
ballast
tanks to accend and would therefore be pumping the
air down and not have an overpressure situation right?
So the only time overpressurization would
occur, is if you were forcing her up with the dive planes only, while
your
ballast tanks were full, and you forgot to pump
down the interior air and push it back from the hull's interior into the
ballast
tanks that would push the water out. If that
occured, your overpressure valves would automatically open those ballast
tank
valves to the hull interior and would pump the water out automatically. The overpressure
valves would be your backup so you never overpressurized.
Those overpressure valves could open your
ballast tank's water inlet valve and using the compressed air
volume of the hull's
interior push the water out of the
tanks using either your hulls expanding atm and then you would be equalized at the surface. So you would
NOT
lose any air out of the hull or the ballast
tanks and the overpressure valves would compensate for you automatically if
you did not remember to pump the air
down.
I hope I explained it good enough and the above was
what you were asking if you were missing Dan.
The latest posts show that even Carsten says it
will work. But he has the same question as you do of "WHY?"
His concerns about the hybrid's complexity for no
depth gain over a typical 1 atm sub's depth capability, make a
lot of sense, as do yours.
So after thinking about it, I think the best thing
would be to go ahead and build a 1 atm sub and make THAT
sub a 1 atm/ambient hybrid. Imagine an already 1
atm sub design that had a max operating depth of say 400 ft. If you built
your ballast system like this for it, you
could compress the atm in the sub by filling the ballast tanks and having those
tank's
valves open to the hull interior, then you would
close off those valve and seal the hull again, and be able to dive even
your
1 atm sub deeper than you safely normally could. At
least we know the 1atm/ambient hybrid idea can be done. It can be
done
looking at it from the view of a normally ambient
that sometimes become a sealed hull that allows it to dive deeper than a
normal
ambient, or we can look at it from the view of a
normally 1 atm sub, that also uses a hull air compressing system to
allow it
to dive deeper than normal also. We know they did
it with the Hunley, perhaps we could use that same principle on a modern
fully
1 atm sub design to increase her depth.
I appreciate your helpful comments and valid points
as do I everyone's.
Thanks.
Bill.
