PAYLOAD: 1,200 lb 



PRESSURE HULL; Elliptically-sfiaped pressure flull, with a major axis of 96 in. and a minor axis of 42 in. It is constructed of 128 rings of 



0.75-in-tfiick plywood bonded togetfier. Tfie radial tfiickness of the rings is 4 in. and the assembled hull is covered with 0.75-in. -thick glass reinforced 



plastic giving a total hull thickness of 4.75 in. The hatch is of steel with a flat gasket seal. 



BALLAST/BUOYANCY: A water ballast tank located within the pressure hull provides ±1 10-lb buoyancy and may be manually pumped or blown 



with air. External ballast tanks are presently under construction. 



PROPULSION/CONTROL; Forward and reverse thrust is provided by a 1.5-hp, 1,800-rpm, 24-VDC motor mounted on center! ine aft. Two 1/3-hp, 



800-rpm motors are mounted on the main motor casing, one vertically and one horizontally to provide vertical and horizontal thrust. 



Pneumatically-actuated diving planes and rudder are also mounted aft for altitude control while underwav- 



TRIM: No static trim or list control is provided. Underway trim is controlled by the diving planes and vertical thruster. 



POWER SOURCE: Four 6-V, 1 20-amp-hr, lead-acid batteries connected in series and one 1 2-V battery are carried inside the pressure hull. 



LIFE SUPPORT: O2 resupply is accomplished manually from a 60-SCF O2 tank and CO2 is scrubbed using a blower to recirculate cabin air. A 



desiccant is used to reduce humidity. 



VIEWING: A single 4-in. -thick plexiglass viewport with an OD of 24 in. is located at the bow. Because of the method of mounting, a viewing angle 



of 1 70° is obtained when in the water. The ID of the window is 1 2 in. 



OPERATING/SCIENTIFIC EQUIPMENT: UQC, speed /distance indicator, water temperature sensor, depth gage, pinger. 



MANIPULATORS: None. 



SAFETY FEATURES: 300 lb of lead in segments formed to the hull are held in place with a steel band around the hull forward of the conning 



tower. The band can be released hydraulically from inside the pressure hull to jettison the weights. 



SURFACE SUPPORT: SUBMANAUT is transported on a modified auto trailer and launched by moving the trailer down any available boat 



launching ramp. No support ship has been used for transport. 



OWNER: Helle Engineering, Inc., San Diego, Calif. 



BUILDER: Same as above.
