Hey guys Dean Ackman here. I now have had my old cad system up and running
for a few days now, and I have a rough concept design.
I am basically very lazy, so I would like to ask a few questions on the
feasibility of continuing with the design, before the hours of research and
(yuk) all that math
Budget <20,0000
1atm
working depth 400 ft fw
2 person sit side by side
relative fast speed
used in lake Superior
Basic Concept
Pressure hull 4' x 1/2" x 8' cylinder with end caps
outside stream line wet hull
ambient trolling motors propulsion static rear multiples
small front side thrusters and vertical
control surfaces for maneuvering at speed
control surfaces activated by hydraulic cylinders (like snow plow)
outer hull containing saddle MBTs 2 sets
trying to achieve positive bouancy,even with full failure of MBTs
manual drop weights to compensate
life support =comppressed air normal outside pressure hull, emergency inside
full 360 fish finder sonars
external cylinder battery pods
I can do most all welding, machine work etc myself I have a pretty good
shop and have built alot of things.
My basic rough assumptions are being based on
weight of 1/2" steel for pressure hull @ 20.6Lbs per square ft
1 cubic ft of fw at 62.4 lbs
5 cubic ft of air per hour per person life support
any thoughts be greatlly appreciated as I be close to getting
in up to my do doo
attached is simple scketch
