RE: [PSUBS-MAILIST] Hydrogen Peroxide: on to the topic of flywheels
Gary,
Such things are often considered in the human powered submarine world but
have been strictly banned because they go against the spirit of the
competition or something like that. I imagine they would give you quite a
jolt. Actually, having seen some of the submarines it might also be
dangerous. That kind of power could probably rip some of the subs in half.
But it would certainly be a fun thing to try. I wonder how fast you could
go?
BTW do you know what kind of efficiency you might gain from a counter
rotating prop (aside from balancing the angular momentum)? We are
considering the idea for next year.
Also BTW, and speaking of the Guiness book and alternate drives, the Uni of
California in San Diego broke the world record for alternate propulsion by
over half a knot with their mammal-like tail drive. Congratulations to
them. It is quite an amazing sub.

One last note on exotic propulsion systems. Here's one I bet nobody
thought of. If you want a great deal of propulsion for a relatively short
period of time build a sub with the propulsion energy stored in
flywheels. I did some calculations on the energy you could store and it's
impressive. However, the forte for such propulsion is in the tremendous
release of energy in a very short time frame. It would make a good drag
sub. You would have to have two flywheels that counter rotated to cancel
the angular momentum (if you planned to turn). You would have to have two
counter-rotating props to couple that much power due to the
torque. Perhaps this would open a whole new page in the Guiness Book.
