Frank,
Another
reason to have a surfaces hip for transit; If not a perfect calm lake, the
passenger in the hull of the sub will be seasick in 5
mins.
For the
captain is everything fine as he can see the
horizon;-)

Onderwerp: Re: [PSUBS-MAILIST] powering a
sub for surface travel
Thanks Jens and all.
I expected to get some feedback about a gasoline generator inside the sub. I
was just thinking how a guy could run on the surface without draining the
limited battery power.
I'm hoping to
have a small outboard on my boat for long distance surface travel and although
it is planned to be small enough to bring inside, it won't be. ( A 20 horse
Yamaha or Mercury will just fit ) The plan is to transfer it to the
surface support boat when diving.
Getting back to the
power thing though, my early designs included a tether with power,
communications, and compressed air lines when diving above 100 feet. This
could have given me 220 volt AC power to drive the sub, with battery
power and no tether for deeper dives. As my knowledge increased and good
advice received from the group it became clear the additional resources
available from a tether system probably weren't worth the extra complexity of
a dual power system. ( 220 volt AC and 36 volt DC
)
As for surface
travel, a small outboard just seems like the most simple for a submarine so
small.
I was
just crunching the numbers in the shop last night and figured it
COULD be possible to run a little generator while driving the sub out
say 5 miles or so to reach the dive spot.
Those little camping
generators run a long time on a gallon of gas and are pretty quiet. Still, 1/2
speed on two Minnkotas won't get you very far in a couple of hours. That's why
the big guys have SHIPS to carry their subs around. Must be nice to have a big
check book.
