Hi Psubbers,
In my limited knowledge - flotation - that is extra
incompressible buoyancy - is used only for ultra deep dives. In my understanding
tits used when a U-boats pressure hull gets so heavy due to structural loads
that it itself will not be buoyant. The classic example of this would be the
Trieste bathyscaphe. Trieste used a gasoline
tank - absolutely incompressible - but not that efficient at - 250 kg lift pr.
m3.
Who do a psubs need this when the designer is
working in the 300 feet range ?? If
he really needs it - my practical idea would be to make use of wood.
Dry pine wood has a density of about 500 kg / m3,
and painted with epoxy or sealed with polyester / fiberglass it would form a
nice simple solution in the depth range we are talking about.
Best Regards,
