I have no intension of using those 2 volt batteries, I was just sharing what I knew (not much) with Malcolm.
They are what I'm familar with, what I've worked with, what I know and have wired, metered, carried, slung by
helicopter, etc. So, the batteries I have are 3 cells each, as you may already know, and there sure would be a
lot of cells once all wired up. I had no intension of using diodes at all.
I've been trying, again, to get some drawings posted to give a better idea of what I'm doing, but this old Mac
(10 years) just doesn't want to cooperate with this forum. So, I'll have to tell you instead. No, the batteries
are not on the "bottom". This is a very unconvensional sub, it is asymmetrically balanced. What I'm after is
jet fighter performance and handling, or at least as close as I can get. I have an extensive background in scuba
(instructor, construction, rescue, even logging, etc.) and am completely bored with it. I have 83 hours on a
private pilots license from when I was a kid and thought I wanted to be a helicopter pilot. I have both
motorcycle and car racing experience. I have a Mechanical Engineering Technology diploma from 1983.
Plus a wack of other crazy experience. The batteries were to be placed above and below my prone position
creating zero intrinsic stability, no righting moment, zero inherent stability. This makes for crisp roll response,
driver control and manoeuvrability. Again, I tell you all this in order for you to better understand my intensions
not so you can redesign or "improve" on it. I've been working on this concept / design for over a year and have
done a lot of research and development. It turns out I should have done a little more on the powering issue
first. I thought I would be okay with what I had.
Because this is a delayed ambient pressure design, it's very difficult and complicated to isolate the batteries
from the cabin. Complicated is not good in my design, it relies heavily on simplicity. (My wife laughs at this one,
she says, "The words simple and submarine do not belong in the same sentence". She makes a good point but
I beg to differ.) I can however direct air flow, so I'm keeping the batteries downstream of the controller and
my mouth. Although I am breathing from a scuba regulator, in the event of an air supply failure, I will have to
breathe the cabin air for a while. There is no conning tower, the only way in and out of this thing is on the
trailer, accept in emergency, but that means losing the sub to the ocean floor.
Thanks for your input though dragonfire, I do appreciate it.
