[gurps] [VEHICLE] of the week 756 – Nexa-III-class Light Orbital Transfer Vehicle

[Onno Meyer]

  This is a weekly posting with GURPS vehicles (and the like) to the 
GURPSnet mailing list. I grant the permission for all non-commercial 
redistribution of my work, but I would like to know if you put it on 
a website or the like. My site is down for rebuilding, but sooner or 
later the old stuff should reappear at   omeyer.gmxhome.de

Nexa-III-class Light Orbital Transfer Vehicle v1.0 (TL10)
  Copyright 2009 by Onno Meyer

  The Nexa III is used as an orbital and deep space transport in thinly 
settled systems. She was designed as an OTV, without the safety margins 
for deep space work, but start-up colonies are known to cut corners and 
to use the little Orbital Transfer Vehicle for trips to the Jump Points 
in the outer system.
  The OTV has a roughly box-shaped frame with two decks. The upper deck 
contains the cargo and a docking airlock, the lower deck holds the life 
support system, quarters for 12 to 15 people, and the control room. The 
efficient little fusion rocket provides 49 km/s delta-V with a nominal 
fuel and cargo load, or more than 100 km/s running light.
  The engine uses 80 gallons of reaction mass per hour.

Subassemblies: Body +6. 
Powertrain: 4,000-lb. vectored fusion rocket; 250-kW RTG; six 
  360,000-kWs rechargeable E power cells.
Fuel: 2,000 gallons water.
Occ: 3 RCS, 12 bunks.   Cargo: 2,000 cf.

shielding.

Statistics
Size: 16'x16'x20'   Payload: 30 tons      Lwt.: 40 tons
Volume: 4,000 cf    Maint.: 3 man-hours   Price: $395,100

HT: 9.   HPs: 1,500 Body

sAccel: 0.05 to 0.06 Gs   sMR: 0.05   Delta-V: 110,283 mph

Design Notes
  Body is 4,000 cf. Structure is light and expensive. Armor is expensive 
metal. Sealed. Computerized controls with duplicate maneuver controls. 
There are 134.8 cf of empty space. Empty weight is 20,000 lbs.
  The vehicle uses the design rules from Vehicles [2nd edition, 3rd 
printing, Dec 2004 errata], VXi and VXii (including the armor volume 
rule) with the text format from Vehicles Lite.
