Standard Small Craft Design *DRAFT v3*

Hulls
Standard hulls for small craft are roughly cylindrical, and come in diameters of 3m, 4.5m, 6m, 7.5m, and 9m. This system is most effective for smaller spacecraft, which have bridges or cockpits smaller than 20 tons.

10t hulls generally have a 3m diameter.
20t hulls generally have a 4.5m diameter.
30t-40t hulls generally have a 6.0m diameter.
95t hulls generally have a 7.5m diameter.

Bridge/Cockpit
The bridge (or cockpit) of standard small craft hulls are housed in the nose of the ship, which forms a hemisphere.

3.0m hulls have an 0.5 ton cockpit.
4.5m hulls have a 1.7 ton cockpit.
6.0m hulls have a 4 ton cockpit.
7.5m hulls have a 7.9 ton bridge.
9.0m hulls have a 13.6 ton bridge.

Main Body Segments
The main body of the craft is composed of cylindrical segments 1.5m wide, with the same diameter as the hull.

3.0m segments displace 0.8t.
4.5m segments displace 1.7t.
6.0m segments displace 3t.
7.5m segments displace 4.7t.
9.0m segments displace 6.8t.

Power and Fuel
One body segment is devoted to the power plant, and one body segment is devoted to fuel.

Maneuver Drive
Maneuver drives are added in cylindrical segments 1.5m wide, with a width of 1m narrower than that of the main body.

2.0m segments displace 0.3t and produce 5 tons of thrust (TL9).
3.5m segments displace 1.0t and produce 18 tons of thrust (TL9).
5.0m segments displace 2.1t and produce 38 tons of thrust (TL9).
6.5m segments displace 3.6t and produce 65 tons of thrust (TL9).
8.0m segments displace 5.4t and produce 97 tons of thrust (TL9).

Thrust produced per segment depends on the tech level.
The formula is: Tons of Thrust = Drive segment volume x TL x 2.

[/quote]Just one problem with your math. You forgot to multiply your segment volumes by 1.5. The numbers you came up with are for 1m segment not 1.5m segment.
 
Yep, you're right. I saw that Friday but didn't update the stuff here.

Good eyes.
