Re: [PSUBS-MAILIST] little sub brother wants input
Hi Alec,
Thanks for the input, that's just the
type of critique I'm looking for.
You see, I am designing kind of
backwards. I'm starting with an asthetic or goal as to how I want the sub
to look (hopefully with some consideration for function) and then looking at it
one system at a time and then the sub as a whole from a functional
standpoint. I know this is a bit unorthodox and may result in a finished
product with a look that is modified from the original concept, but, this is
only an appearance concept not a functional design
yet.
The saddle-bags are going to be
ballast tanks, so I'm sure that
some changes will need to be made to work out front to rear volume ratios
for ballancing the trim as the tanks are blown. The 'bump' directly
forward on the bow is a light, and there is (difficult to see) a conical
viewport angled downward on the bottom-forward portion of the pressure
hull.
As the sub appears, it has a cockpit
type main viewport. If I decide to go with a one atm. sub, that may be
changed into a heimspherical viewport for strength. I loved the cockpit
designs that Doc has on "Bionic Dolphin" and some of his planned projects, and
would really like to keep that even if it means sacrificing a lot of depth
capacity.
The pressure hull will be two rounded
double-cone or sphere shapes <>|<> or O|O
connected together at the rear of one and forward on the
other. The saddle-bag ballast tanks will be formed separately and attached
to either side of the pressure hull structure.
Below aft are the battery-pod tubes
(one visible).
Thanks for taking the time to have a
look!

Bob,
nice drawing but a bit hard to interpret! The ballast tanks, if thatīs what
the "saddle-bags" are, seem an odd shape and I'm interested in the rationale
for it. It would appear from the shape that their center of buoyancy would
shift aft to forward as you blew them... could complicate things. Also, it the
"bump" on the front a viewport? It seems a non-standard geometry that would
present problems if you go for a 1 atm design.

Hi all,
I know this is the usual question
when a newby like me updates a design, but, would anyone like to go to my
site
If anyone has the time, I sure
would appreciate any thoughts you might have on the new layout.
