This JET or Nozel system has been used several times, and Cousteau's
Saucers used it extensively. It's cool but seems to be not very
efficient. Motors like the Hard Suit that Phill bulids
with variable fore and aft pitch seem to be the hot ticket. Another
good method is some derivative of the Voit Schneider drive which
is widely used on Tug Boats in close harbor work. I haven't
ran across many good pictures of Cousteau's twin boats but here is a site that
has one. Dave Banks
I was looking up submersible water pumps online
today.
I noticed that there were several models that
were 12 volt battery powered models that were home water supply backup
pumps.
I saw one model that was an oil filled
submersible water pump. This would be nice since it would already be
pressure equalized.
I made me wonder if these battery powered
submersible water pumps could be used as thrusters on a wetsub.
The advantages of this would be that there
would be no exposed propeller, the unit would be oil filled and not need
equalization against
the outside water pressure, the unit being
small could be installed within the wetsub's stern with it's exhaust going
out thru a hole in the stern,
you could even install them in the side of the
sub so they could spin your sub easily as a side thruster.
Has anyone here looked into using battery
powered submersible oil filled water pumps as a means of propulsion for
their sub?
Love to find out more about the pros and cons
of this.
Kindest Regards,
Bill Akins.
