Habitation ring:
Radius to surface of floor of ring: 37.69 metres
Rotation: 3 rpm
Centrifugal acceleration (artificial gravity) at surface of floor of ring: 3.72072 m/s² = Mars surface
Circumference: 236.8 metres
Width of ring: 19 metres
Thickness (ceiling height): 2.4 metres (7' 10.488")

Standard cabin:
depth: 4 meters
width: 2.4 metres (94.488 inches) less thickness of wall
Ceiling height: 2.4 metres (7' 10.488")

Standard cabin furniture configurations:
All: toilet with sink 32.244" less thickness of wall x 52.48" less thickness of wall
All: shower: 30" x 30", polycarbonate wall/door on 2 sides. Opaque insert available for wall/door.

Economy configuration:
3 bunk beds, total 6 bunks. Each 30" x 75"
Upper bunks attached to wall, can fold up like pullman bunks.
Two lower bunks can slide together to form a Queen bed, 60" x 75"
Two end tables for above two bunks, attached to end wall, open below so drawers can slide beneath end tables.
All 3 lower bunks have 2 rows of draws beneath. One row intended for upper bunk, one for lower bunk.
When lower bunks are slid together, end tables can be moved from centre isle to outer isle.
All bunks (upper and lower) can lift mattress to open storage compartment beneath mattress: 4" deep (10.16cm)

Alternate economy configuration:
2 bunk beds, total 4 bunks
The bunk bed (2 bunks) across isle from toilet/shower removed. One chair available. Luggage can be stored on the floor. Bungee cords available to secure luggage to floor/walls.

"Single" configuration:
Murphy bed, one side of bed folds into side wall. 60" x 75"
The reason for folding sideways is to leave window at end of cabin exposed.
Dresser on wall opposite bed
Desk that lifts when bed is folded into wall. Desk surface remains level, lowers to floor when bed deployed.
Folding chair, stored in dresser.

Military configuration:
3 bunk beds, total 9 bunks. Each 30" x 75"
No drawers. No end tables. 3 bunks high. Bottom bunk on floor.
End of isle covered by lockers: 3 wide x 3 high. Each 11" wide x 31" high x 24" deep. Sheet metal.

seems that we can migrate the fluxbb discussions to this format.

Atmosphere specification, for large ship and Mars habitats:
2.7 psi O2
3.5 psi N2
1.148 psi Ar
Total: 7.348 psi total = 1/2 Earth atmospheric pressure at sea level

Spacesuit: 3.0 psi pure oxygen

Note: maximum nitrogen in higher pressure environment for decompression with zero pre-breathe time is total pressure of lower pressure x 1.2. So for suit with 3.0 psi, max nitrogen if hab = 3.0 x 1.2 = 3.6 psi. Pressure is reduced to 3.5 as a safety measure.

Also note: once humans start to breathe, some O2 will be converted to CO2, and water will be added as humidity. Water source is moisture from lungs via exhaled breath, and sweat.

Metric:
18.615 kPa O2
24.131 kPa N2
7.915 kPa Ar
Total: 50.661 kPa

Spacesuit: 20.684 kPa O2
Round metric figure for O2 and N2 to 2 significant figures. 3 at most.

This deep space vessel is defined by a set of specifications laid down by RobertDyck, Moderator of NewMars.com/forums.

Posts in this topic will be about those specifications.
