Hi all,
I've brought up this subject before, but are
tackling it from a differant angle.
How much pressure is exerted upward on a hatch
at the moment where the
submarine
just submerges below the water? This is the point
of most force before external water
pressure helps close it.
If you took your submarine, filled it with water
& hung it upside down, would this be the
same amount of force, or close to it.
In wich case if you have a design like Franks
flying saucer that angles up to the hatch,
you'd have a lot more force acting upward on the
hatch than a K250 where the lifting force
would be spread more evenly along the
hull.
Am I thinking right?
Alan
