[PSUBS-MAILIST] Transit Outboards

Great idear Frank,
 
I would expect that with some of the smaller outboards you could put them inside the sub, perhaps in a special built case, with out the need of a surface boat. You would want to make sure the gas didn't leak out.
 
I had thoughts along this line some time back, and was thinking about making a very small and light pressure hull to custom fit over the outboard rated at the same working pressure as the sub. The said small pressure hull could be made out of aluminum, steel, stainless steel, titanium, FRP or some other composite. It would be a great place to practice building and testing composite hull designs, since if it fails, you won't likely be harmed by it's implosion.
 
For this type of arrangement you will likely need manually operated valves for the exhaust and intake.



Regards,
Brent Hartwig

Concerning surface transit.....What if you had an outboard motor on the back, and when your sub reached the dive site, transfer the (small) outboard to the support boat. A 20 horse motor should be easy to disconnect and  pick up, transfer to a motor boat, and would likely power a small sub at a good speed, while not using any battery power. I assume you would have a surface boat as a safety precaution when you're diving the sub.
If the outboard mount was connected to the subs rudders, you could use the same steering mechanism to steer the outboard. Frank D.
