Hi forum.
Why not have a diver lock out chamber as an
escape device instead of a burst/scuttle valve for the main hull? The only
reason I can think of that someone would
have a valve to let water into the subs main
hull, is so the pressure inside would equal the outside so you could open
the hatch to bail out. That means the sub would be dropping like a
rock at that point and you probably wouldn't make
it to the surface anyway by the time the sub flooded enough for you to open the
hatch and bail out. But with a
diver lockout chamber you wouldn't need to flood
the sub, just get into the lockout chamber and flood it and then open the
lockout chamber exterior hatch to escape.
Of course you would be lucky to escape anyway in a
situation where you might have to use the lockout chamber because if you were
going down by the time you made the decision
to bail out via the lockout you might be so deep
your body may not be able to stand the exterior water pressure. Also you
probably would only get one person out since there would
not be enough time to blow out the lockout chamber
for another person to use before the sub imploded if you were going down fast.
Totally depends on your depth of course.
Has anyone built a p sub that has an escape pod
built into it that could
jettison from the main sub and has its own
adjustable buoyancy? Just an egg, tube, or sphere that has no motor and a
simple breathing air and buoyancy system, for emergency bailout built to hold
the entire crew capicity of your p sub.
Kind of like an adjustable buoyancy non line
tethered version of the emergency McCann resuce chamber diving bell that
recovered submariners invented and built by Commander Charles B."Swede" Momsen the inventor of the momsen
lung,

Only much more streamline and actually built into
the sub so it doesn't stick out and can be jettisoned. Definately would increase
the size of the sub though to have this. I like this idea much better than
flooding the hull and breathing thru a
regulator while hoping the main hatch will open and
having to endure hypothermia and extreme outside water pressure.
