[PSUBS-MAILIST] Dif. Between Ambient & 1ATM



Guys,
From my understanding, the differance between ambient hull designs and 1ATM is that ambient is non-pressurized (resisting the pressure by structural strength) and that 1ATM is pressurized (resisting the pressure by structural strength & by internal air pressure, kinda like a 2L bottle of pop before you take the lid off. :o) ).
 
Also, I was wondering if it would be feasible to have a submarine wet for diver entry and 1ATM after they are in. (It would be underwater, and the diver would open the hatch, get in, close the hatch, and then blow all the H2O out of the cockpit).
 
Am I confused, or what?
 
Just wanting a little clarification,
