Hi Alan,
Hydrogen is generaly a bad thing in submarines. It it
explosive.
Gary Boucher gave a wonderful review of his Sonar
dissertation at the 2004 PSUBS Convention. His power
point presentation is at
http://www.psubs.org/convention/2004/presentations/garyBoucher/Sonar_Presentation.ppt
and his lecture was recorded and available on DVD at
the PSUBS Store as part of the 2005 PSUBS Convention
set of DVD's.
Others have mounted fish finders to their subs as a
simple sonar.
Regards,
Ray

Hi guys,
An idea that has been bouncing around in my head
for a little while is a rocket-powered submarine.
Well, not quite, as you'll see. Hydrogen and oxygen
(obtained from the water) would be injected into a
chamber and then ignited with a spark, which would
then make the hydrogen and oxygen blast toward the
aft end of the chamber, turning a turbine, and
providing power to the prop. The hydrogen and oxygen
would be injected at intervals into the chamber so
that the turbine would not spin apart, and also
because a rocket engine (especially this type) is
about 3000 times more powerful than a gasoline
engine of equal weight. Because it would be running
from H and O drawn from the water, it
would/could/should never run out of fuel. A machine
would be on board the submarine to separate the two
gasses. Oh, and rocket engines may reach as much as
6000°F (3300°C)!!!
I know that this question was asked once before,
but how much air does one adult human need in an
hour?
I am currently designing a 65 foot long 1 ATM
sub with a ten foot outside diameter, and carrying
8-10 passengers, capable of going to 300 or maybe
even 600 feet, in the basic design of the big
nuclear subs- cigar/blimp-shaped. Any ideas to how
much it would cost?
Carsten- what are the specs on your big sub:
weight, length, crew/passenger capacity, submerged
time, speed, etc. Did you build a smaller sub first?
I'm mostly interested in multi-person subs, but all
subs are intrigueing.
Has anyone on this mailing list made a sonar
setup?
Thanks,
Alan
