I still need to purchase the handbook of acrylics and other standards to nail down specific dimensions for viewport lenses, housings, pressure vessel, etc. so these numbers are just estimates right now. Pressure vessel was designed based on excel calculator obtained from the psubs site.
Length:
20'
Beam:
3' 10"
Est. Weight:
TBD, probably around 8,000lbs
Trim:
internal soft or external hard tanks TBD
Air System:
HP air; 3 externally mounted 3000psi 100 cu ft tanks. Shall be piped in 2 independent banks for redundancy.
Life Support:
-Externally mounted O2 tanks . Shall be piped in 2 separate banks for redundancy.
-CO2 Scrubber
MBTs:
4 soft annular saddle tanks. Tanks shall be sealed to pressure vessel as well as have straps on both ends. A supplemental forward soft ballast tank will also be in the nose.
Pressure hull:
40" OD, 5/8" thick
24" OD Conning tower
Internal T stiffeners. 24" apart
1" hemispherical heads.
plate thru-hulls
Propulsion:
1 10-20kW (TBD) DC motor to drive main prop
2 fixed bow thrusters
1 vertical fixed thruster
Control Surfaces:
Tail dive planes
Rudder
Foreward Dive planes
Power
48V main propulsion motor
24V vertical and bow thrusters
24V lights, nav, etc.
Viewing:
Conning tower Acrylic Dome
2x side viewports 6" internal viewing
1x forward viewport 60 deg downward angle. 10" internal viewing
External:
Molded fiberglass or some other type of plastic/composite to achieve a streamlined shape. parts will mounted to an external structure, and also act as service panels.
Batteries:
Now this one I'm running into snags with. I would like to have external pressure compensated batteries, but i cant seem to find much info an compensating AGMs. The busby book gave some good info, and I saw a few white papers regarding it, but besides that cant find much.
Emergency:
Drop weights planned.
Possible jettisonable batteries a possibility.
