Bryn the 2300AD guy
Cosmic Mongoose
About 22 years back, I wrote a brief set of conversion notes from the 2300AD Naval Architects Manual to Traveller dTons for Colin Dunn. These were the basis, I believe, of the pre-AEH ship design system. When I got the AEH it was obvious there were a lot of problems with it, and I started writing a Traveller dTon conversion for my own version of Star Cruiser entitled "La Grande Frégate." I never finished, but let me start with some notes and rules I did write:
Step 2 - Hull Design
In NAM, the hull was wrapped around the interior. Due to there being no separate volume and mass, herein we adopt the opposite approach. The hull consumes dTonnage, which is a catchall single figure used for volume and mass (wherein 1 dTon = 14 m3). We generate the hul from a series of geometric objects, of which the cylinder is the norm. Not having corners, cylinders are much stronger than rectangular sections. If using other shapes for sections (such as a cone for a nose cone), use geometry. One point of material value = 100 m2 of surface.
A hull typically consists of a series of cylinders with and without internal caps for subdivision. All ends must be sealed, and the easiest way is to but two caps of the largest cylinder. The MV of various cylinders in in table 1:
Table 1: Material Value of Cylinders
The Kennedy class frigate is created thus:
The Kennedy has a large engineering section (750 dTons) which will house a large fusion reactor (ca. 500 dTons), the drive, weapons and other systems. There is a step to allow superfiring of guns forward (six bearing forward, 4 aft), and a narrow 30 m section which accesses the spin sections and houses the sensors etc.
The vessel is 1,150 dTons and has a total number material value of 61.5.
The hull is unarmoured, and the material is converted into displacement and cost by multiplying by the values in table 2:
As the Kennedy is unarmoured TL-12 composite and hence the dTonnage used is 61.5 * 0.1 * 1 = 6.15 dTons. The cost is MLv6.15. Had the hull been armoured, each armour level would consume 2*6.15 dTons (12.3) and cost MLv12.3.
