Hi,
For the past 3 years I have been making R/C
submarines and so have SOME idea of sealing etc. I have a full workshop
available to me (milling machines, lathes, cnc lathes, drills... etc)
and can, but prefer not to weld. I generally prefer to use
fibreglass for my projects but if I have to weld then I have the
option. I am fairly confident with electronic circuits and have all
the electronic equipment and advice I should ever need. Anyway, the reason I'm
telling you all this is that I would love to make my own PSUB. I've
already bought a book about designing submarines (it is in the post and I
can't remember the author/title) and have started looking through
the Busby(sp?) book on the PSUBS.ORG site.
My specification is basicly:
1 man
60m operating depth
100m crush depth MAX (where I will run it
(fresh water) won't be deeper than that)
1 ATM
Fast
Electric
Cheap as possible
'Trailerable'
No compressed air/CO2 absorbants
Inside I want a seat, can't be doing with lying on
my front.
Ideally 1 man operation for in/out the water -
(Think that's all)
So with this in mind I have lots of question for
you guys ;-). I know that people new to the hobby sometimes so I apologise in
advance. Anyway here is my list:
It needs to be as cheap as possible, however
obviously I don't want to endanger my life. So I was thinking about CCTV cameras
on the outside in pressure housing, with a array of monitors on the inside. Any
thoughts? Things I thought about : Increased temperature and battery
draw. This would however, allow me to bypass the acrylic dome
aspect.
Fibreglass hull. Now the problem I have here is
that I could go the KEVLAR route, but that would bump up cost. I guess carbon
fibre would be a compromise but then even that is still expensive so may end up
going the CSM route. Recommended?
Propulsion. I have a 2HP (36V) electric motor left
over from another project, now would this be enough to propel me through the
water at a reasonable speed? Not sure if you call it dynamic diving (use of
hydroplanes to dive) but that is what I was thinking and so will need some
speed.
The other thing that I always try to aim for when I
made subs in the past, was to make battery power the only limiting factor. So
things like CO2 absorbant/air scrubbers need to be 'bypassed'. I was thinking
about changing the air every 10? minutes so as to eliminate this problem (open
hatch, nothing fancy). Anyone see a problem with this?
Right I think that's it for now, if anyone can see
a problem that I might encounter I'd be more that happy to redesign/discuss
it - better to make errors than then later.
Hope you guys can help,
Thanks
Michael
