... So
imagine yourself at only 2 atm or 33 ft of pressure on your body, but
actually diving to 99 feet and staying for a maximum of 205
minutes without any deco! Wouldn't we scuba divers
love it if we could do that! A hybrid like
this would allow us to. I would say it would be worth the extra trouble. What do
you think Paul?
I'm
with you Bill, sign me up for a pressure-limited cabin! But I
am starting to wonder why not just limit it to 1atm. :-)
Once I start thinking about building a crew compartment that handles
3atm and maybe 1atm of overpressure, well it seems like why not just
build a traditional 1atm boat? But this hybrid sub design is
fascinating and I'd like to see it sketched out.
Now I would like to know what hull strength I would
need for a 1 atm pressure vessel to withstand 2 atm of outside water pressure.
Probably have to build it with a safety factor for 3 or so atm
just to make sure it was safe. I wonder what steel
thickness I would need or if a 1/2 inch thick kevlar wing tank would
withstand 2 or 3 atm with 1 atm inside it? Any help here fellas?
Well that's the rub, isn't it? My feeling is that many
engineering types would be comfortable designing something for
themselves to use but would be pretty hesitant to give someone else
recommendations on pressure vessel details. Is that right?
Sorry I haven't been on this mailling list long enough to know what's
been done and discussed in the past and I didn't find anything on
PSUBS.org or by searching it with Google.
