[PSUBS-MAILIST] new sub project

Mon May 25 07:02:44 EDT 2015

Alan,
I was thinking about horizontal 12 inch dia tubes on each side that pivot.  The tubes would always stay horizontal while the sub changes orientation.  I also thought about a 24 inch inner tube, like you mention for a back up even.  Surface transits could be problematic, maybe the sub could tip enough to raise the dome.  Honestly had not thought of that.  My main interest is to have the sub operate from my boat, so surface transits would be short and could be done in the vertical position.  The forward thrusters would be on the end of the tanks.

 Hank,how would
 you configure the ballast tanks?You could
 have something like a truck inner tube around the top
 sectionthat could
 be deflated & cause very little drag & would also
 give good stability.However
 you wouldn't be able to transit horizontally on the
 surface.Alan

 Alec,
 I am not
 thinking flyer at all.  The water clarity would not support
 the speed.  I am thinking of a simple tiny light sub that
 can launch anywhere even off the deck of my boat.  It is
 just a though right now.

 For now I am enjoying my what seems gigantic
 bow dome.  The visibility is unbelievable, the modification
 cost and effort has been well worth it.  As a bonus, my
 payload is back to 500 lbs plus.  I had to fill the sub
 with steel plates to get it to sink.  :-)

  Indeed! Except mine went
  vertical only for emergency exit rather than
 as standard
  procedure.  It was not going
 to have any freeboard to speak
  of in
 vertical mode, so you would climb out in a hurry and
  watch her sink from under you. The method of
 going vertical
  was dropping the emergency
 weight, which was located at the
  very
 front. More than the front actually, it stuck out and
  constituted your crash bar. The sub was a
 "flyer",
  a poor man's Deep
 Flight. I had her 90% complete when I

 bought Snoopy, and the flyer project sat untouched for
 many
  years while Snoopy took up all my time
 and served as a
  classroom. The sub I'm
 finally finishing up now recycles
  the flyer
 hull, but redone to be conventional. Well,

 conventional in the sense of having ballast tanks and a
  conning tower - she's actually a pretty
 bizarre beast as
  the folks who come to the
 convention will see! My conclusion
  was that
 a flyer must be great fun but requires both

 unusually clear water and a vessel capable of laun!
   ching the sub at the dive site. If I owned
 a
  mega yacht and cruised the Galapagos, a
 flyer would be just
  the thing. But what
 I'm aiming for now is radical

 simplicity, whereas the old one was all touch screens,
  servos, PLCs, and such.

  Best,

 Alec

 Yes,
  you float it to the dock side, then
 tip it vertical to get
  in, close the hatch,
 tip it horizontal, and your away. 
  Saves
 building a CT that my 200lb sexy frame can fit into
  :-)
