... 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.
