Hi John.
Please be sure and share some pictures of it with
us when you get it built ok? I'd love to see your hydraulic jet vectored
nozzel system.
What an interesting propulsion system.
Bill.

Hi Dan,
Well I guess we will see... I just ordered my
"test" 1 HP motor and pump and am going to bread board the system before
coming to any final conclusions. (Once the system is up and running I am going
to mount it underneath a small boat of mine for testing) But my submersible
design is much like the Soucoupe, I have no propellers and they would probably
not work in my case for the designed shape of the submersible.
A 1 HP
electric motor turning an efficient hydraulic pump can push a whole lot of
water through two vectored thrust nozzles I have learned from my research and
calculations. The noise problem, if it exists, can be solved through sound
proofing the motor mount and motor housing. The hydraulics have the advantage
of being easily throttle able and require only a small hull pass through as I
have mentioned.
Plus I am interested in the concept... But
experimentation will tell. If it does not work at the bread board stage, then
I have all the parts for a great log splitter!
John

John,
Is it really going
to be that worth while to go with hydraulics? You must
be planning a
really small system if your total power input is only one
horsepower. You have some power lost to heat in the hydraulic system
also.
Then you have the noise of the pump to listen to. For a total
of one
horsepower, wouldn't it be much easier to just use electric motors
in pods
with a pump shaft seal?
