Re: [PSUBS-MAILIST] fascinating stories



Howdy Jeff,

Right !  I should take more time to elaborate a little more instead of
tossing out a comment without explanation.  I realize the intended
purpose of the wheels for the NR-1.  However, I imagine there are times
when the NR-1 is stationary resting on its wheels with propulsors
maintaining stability in which case the hull/keel is not touching bottom.
So, I'm suggesting to "think outside the box" for a moment and not look
at it so literally, but look at the wheels as two points that offer
separation
from the keel and the sea bottom.

I've been scouring my backup disk for a zipped folder containing info
on hull stabilizers and stabilization, but I can't find it!  Anyway, in
this folder
is a pic of a submersible in dry dock showing the bottom part of the
hull.
There are 3 fins, two foreward and one aft/stern forming a triangle
that also serve as strut support when the submersible is at rest on the
sea
bottom.  Another "conceptual graphic" shows the sub at rest on these
fins.

With a little imagination and engineering savvy one could combine
"wheels"
or "soft points" to these fins and spare the keel or hull from wear 'n
tear.
'Just a thought.

Now...how about another comment/idea without explanation..."curb feelers"
 This
may be a litttle [ probably a lot ] before your time.  : )  I don't see
them on cars
anymore.
