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

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

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
