Propulsion

• Early brainstorming sessions led to basic
  foundation of current propulsion design
• Pilot in prone position, resting on two
  symmetrical 1 ¼ aluminum shafts braised to a
  t-bar underneath
• The two shafts contain eight ft long aluminum
  pushrods that slide within
• Pedalblock attached to t-bar, attached to
  pushrods by cable

9
Control

• Dive planes
• Inspired by nature
• NACA airfoil 0012 cut into blueboard with
  polystyrene wedged between and covered with
  fiberglass
• 3/8 in threaded steel rod bent to 90 degrees and
  embedded in plane with epoxy resin
• Rods enter the hull 1/3 from nose and below the
  midline
• Rods attach to ½ in aluminum electrical conduit
  bent to 22 degrees to form a handlebar

• Stabilizers
• Design
• 4 stabilizers fixed to the hull at the rear of
  the vessel, spaced at 90 degrees

10
Life Support

• VO2 max testing at University of Maryland for
  both pilots
• Testing suggested 40 cubic ft tank sufficient to
  meet ISR regulations for each run
• Submarine includes
• 63 cubic ft tank with octopus attachment
• 13 cubic ft pony bottle with single regulator
  attachment
