Re: [PSUBS-MAILIST] Working subs



I must have misunderstood the pictures you posted. It looked like there was a hatch at the wide end that projected well above the water when surfaced and flipped bow-down. My thought was: make that the normal condition for entrance and egress.

Hi Marc,  Wow to the Philippines and back in a split second - the internet

When it is flipped, like a spar buoy,  you wouldn't be able to get out.  It
would most likely be in that configuration in heaver seas, with limited
freeboard in the horizontal position you could easily get swamped.  The
freeboard in the flipped position would be much greater.

I am very fond of the spar buoy configuration, and FLIP was my intro to
it as well. Perfect for habitats, but I admit I never thought of it in
connection with a personal submarine. Quick comments:

I'm assuming that your design will flip by shifting water ballast or
(better) a solid weight fore and aft?

Instead of an additional hatch aft, why not make that the only entrance?
The fewer hull penetrations, the better...

Best,

Hi Rick,
                My first model was patterned after Deep Flight Aviator,
but I decided to make a canard design for the wings - similar to an
aricraft that I always liked, the Varyeze.  That first model was small ,
I think 1/12 scale.  I made it out of foam and fiberglass.  It was ok
for a general cool looking sub but as a practical matter it didn't make
much sense, I found myself trying to crame everything into this design I
made, where the functionality was not fully developed.  My second design
was based more on what I could realistically do in the real world and
was a larger scale.  It was made using cardboard ( or maybe very thin
plywood) and I actually made ribs and then filled inbetween with foam,
then I fiber glassed over the whole thing.   Hot glue is fun to work
with - instant gratification !  One problem I had was that the model was
too buoyant so I had to compensate with lead placed in some strategec
locations.  When I first placed it in the water it turned upside down (
shades of needle fish ! )  that got my attention right away !    I
changed my design because of that.  Here is a link to some pics:

    I'm finding that out now.  I found that Gorilla Glue was probably my
    best bet - unless I wanted to keep making batches of 5-minute epoxy.

    The scale human figures are invaluable.  You find out right away
    what works in terms of ergonomicas, fit, points of view, etc.  It's
    enlightening.

    What materials did you use for your models?

        Actually Rick,  I benefited immensely by making some models at
        the begining stages of my sub design.  Even with the actual
        methods of construction I found that in order to make a sturdy
        model you needed to think about these things even on a small
        scale.  Also when I was trying to come up with a over all "look"
        for my sub the term "form follows function"  was a guiding
        format for me.

                    I purchased, as part of my modelling efforts, a
                    series of anatomically correct mannequins.  They're
                    about two inches to the foot, so a twelve inch high
                    figure is equivalent to six feet.  The joints appear
                    in all the right places as measured against a human
                    figure - me.  They also bend naturally.  I was
                    fortunate to find them at $10 CDN each.

                    They also have really cool uniforms.  Seriously,
                    making models, scale and life-size, can't be
                    overstated.  Cardboard, poster board, wood, metal,
                    copper pipe - whatever works.

                        Hi Alan. Evolution of design is the best
                        approach. You have a full size mock-up ? Another
                        great idea. It worked well for me. I made a lot
                        of serious changes to the design after making
                        mock-ups. After I zeroed in on the hull design I
                        made models too. About 1/10th scale and used
                        them to experiment with different ballast tank
                        designs, water flow, weight distribution,
                        balance, etc.
                         That was a really fun part of the process.
                        Sitting inside the mock-ups and imagining where
                        the windows would go, how the controls would
                        function, where all the stuff would sit, how
                        seating would be arranged etc.
                        It's been a multi-year process and a LOT of fun.
                        Looking forward to seeing yours as it evolves.
                        Frank D.
