[PSUBS-MAILIST] A question to fire up a debate

["Ashman Vi" <ashmanvi@hotmail.com>]

Dear all,
  Freely i will admit i am no engineer, nor someone who thinks his ideas are 
flawless. When im at work i have alot of free time, time spent reading Psub 
archives ( I think i've managed 4 years so far. )
And spend other time looking for rescources out-with Psubs to help me in 
some understanding of hydrodynamics, u / w pressure on hulls etc etc, just 
about anything i can get a hold of online.

But what i love about this website is that you guys all have certain fields 
which you guys know about either, professionally or through experience and 
can discuss ideas with feedback.

So my question to you guys is this( Finally i hear you say lol )

If a sub was built on for the purpose of gliding say 50 meters MAX u/w, and 
a hull was fabricated from G/RP composite materials or steel to a thickness 
of say 2 inches ( Or whatever was needed ), plus internally reinforced by a 
steel frame ( If needed ).  The pilot cockpit being the only air bubble ( 
say like a race car, with a canopy ) Given the MAX depth, Hull wall 
thickness ( Be it steel or Composite, up for discussion ) could you 
construct the Hull in a less cylindrical section, and still be an ambient, 
or even 1 atm sub?  considering the hull was designed for this shape? a 
lightly squashed  -> O <-  O ring?

  I've looked through your archives and noted that the majority of you have 
chosen the deep path to Subs, and your discussions *for the main part* 
discuss pressure relating to these deeper depths, and hulls constructed with 
this application in mind. Any feedback for the not so deep knowledge would 
be greatly appriecated.
