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.
