Michael,
You made a good start with R/Csubs and reading. I shall
give some awnsers an commets to your questions.
At the list is steel the material of choise for reliability
and ageing reson
1
man
60m operating depth
100m crush depth MAX (where I will run it
(fresh water) won't be deeper than that)
[Emile D.L.van Essen] for these depths a safety factor of 2+ is common 1 ATM
Fast
[Emile D.L.van Essen] Why? Electric
Cheap as possible
'Trailerable'
No compressed air/CO2 absorbants
[Emile D.L.van Essen] Ballast control should be done with compressed air. A life support system is easyer and cheaper than yoiu think. 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)
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.
[Emile D.L.van Essen] I can help you with a dome (580 mm O.D. @ 30 mm thick) The view is worth it! 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.
[Emile D.L.van Essen] You can make a R/C sub slightly buoyant and you can dibe dynamic. A psub need freeboard . Ballast tanks should have 20-30 % boats volume; that dont dive with 2 HP. 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?[Emile D.L.van Essen] As
said, a LSS is not so difficult but a internal space of 500 liter gives a safe
dive time of 1/2 hour. You can use dive gear for
emergency.
Groet,
Emile
