submarine [Was: end caps]
"...enlarge the size of the
endcaps and set a cylinder between the caps. (in the way that you get a double
hull around the circumference...
Such a cylinder should met the endcaps
some inches behind the smal radius... You will lost some space but You get a
good stability and extra tank capacity...
If there are additional radial
bulkheads lets say every 45 degree or so ... the inner cylinder canīt buckle
and the thickness can be relatively thin..."
And if I understand what
Andre's describing here, it sounds to me like (at least in the lower half of
the hull) those compartments created by the radial bulkheads could be used as
integral ballast
tanks.
