Hi Vance. That's not only a very scary story, but illustrates a good
point.
If our little sub got really stuck, like with a rope around a prop, there's
no way we're going to get it loose with a drop weight or lift bag or
whatever.
To jettison the snagged part makes good sense.
Although there's not many places my sub can get snagged, it's always
possible ( hell, even likely ) that Murphy's Law will find that one spot
and hook something in there.
I'm trying to think of a way to jettison something like a thruster, but
nothing comes to mind just yet. Certainly something to consider. I'm not too
keen on the "explosive bolt" concept, but let me ponder this a while.
Maybe something like a latched motor mount, with the shaft using
a spline that can slide off. The wiring could be fairly easy to release, and the
latch could be operated like a drop weight mechanism where a hand pump and
hydraulic cylinder disconnects the mount.
HMMMMMMMM....lots to think about here. Thanks for that Vance. Frank
