I do have plans forming to be
able to operate my sub unmanned as a ROV to greater depths then I would want
to go manned.

Brent that bottom link to the seamagine video was
great.
As you know I'm looking at inflatable ballasts.
The advantage is, your not exellerating or trying
to stop a large mass of water
in your ballast tank.

Subject: [PSUBS-MAILIST] Collapsible
Amas and Saddle Tanks
Hey Glen,
Sounds like we are on the same
chapter. I've been working on designs for collapsible MBT's for a
couple of years now. It started out with a need to conceal inflatable
saddle tanks under spring loaded side panels that would simply open when the
saddle tanks were inflated. Now I working on the design for my KLH-500
inflatable amas to collapse into the narrow aluminum standing deck that runs
above them. The design currently has a aluminum or UHMW cover panel that
mirrors the profile shape of the said ama decks, and is attached to those
said decks with a UHMW spring loaded hinge means, that is attached to
the inboard side of said decks. There is then a number of nylon, seat belt
type bands, that go around the inflatable amas and feed into a spring loaded
spool. This way as the amas are deflated with either just opening up the
valves with a light spring loaded check valve on it and letting the air out
of the MBT's as you would for a normal dive, a mini cordless wet dry shop
vac, or a pneumatic powered vacuum generator, the lower cover panel will
just close up below said upper deck and hold in the inflatable
ama.
The other issue I'm currently
working on, is that I might need to move the amas out further from the hull
then I had first planned. To allow more room between the amas and the hull
for the side thrusters water flow when they are operating in a vertical
fashion. This might very well put me to wide to trailer the sub,
unless I make the be able to hinge up of down towards the subs axis. I
also may wish for them to hinge down to make the sub have more freeboard for
easier launching and recovery by a more standard trailer.
Having a floating trailer,
configured as I've spoke of in the past would take care of the latter
issue.
SEAmagine has being using the
inflatable amas configuration for some time now with great
success.
On a side note many
of the SEAmagine acrylic pressure hulls have a FOS of 7.

Brent remember you were playing with the idea of
inflatable mbt's have you ever thought of a square instead of round shape
with a inflatable bladder connected to a plastic flat base plate running the
length of the mbt's with stainless steel springs that are connected to the
bottom of the plate that once the purge valve of the bladder is opened
the force of the springs will collapse the bladder on surfacing will be
inflated by closing purge and open compressed air valve which is on the same
line could be more rectangular shape to shorten springs any comments
welcome

Good idea with the anti fouling Glen, That reminds me
of a design I have been working on for doing a freshwater rinse of the
interior of the fully floodable wings in my Batic THUWG sub design, and a
flying submarine. I just planning to mount misters and/or sprayers
in such a matter as all the internal surfaces would be rinsed off. Frank
could install some plumbing inside his tanks to do just that, and use it
for a freshwater rinse and spray the chlorine with out every having to
open the inspection window.

Hi Frank D
Maybe you should make a spraying wand that you can spray anti
fouling into all the cavities.And like you say have some kind of
inspection cover that the authorities could use to inspect your mbt's anti
fouling comes in a different colors.I would love to see your MBT's
design.
