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 Onno Meyer, 2007-09-24
Improved Spaceplane v1.0 (TL9) Copyright 2007 by Onno Meyer Many space exploration scenarios require a cheap and reusable launch vehicle. The spaceplane can be used in reasonably realistic far future games. It has ten seats and a total payload of 10 tons, including the passengers. The spaceplane uses a turbofan for horizontal takeoff and the flight to 10 km altitude and 3,200 kph. There the rocket engines ignite for a climb to LEO (approximately 200 km and 7.8 km/s). A delta-V of 800 m/s remains for docking maneuvers and the reentry burn. Reentry takes the spaceplane into the upper atmosphere, where drag brings it down for a dead stick landing. The turbofans burn 1,200 gallons of jet fuel per hour and the rockets burn 1,375 gallons of HO per second. A full load of fuel is $23,600. Subassemblies: Body +8, ten retractable Wheels +3. Powertrain: 120,000-lb. afterburning super turbofan; two 500,000-lb. chemical rockets; four 270,000-kWs rechargeable E power cells. Fuel: 1,200 gallons jet fuel (fire on 13); 200,000 gallons HO (fire on 13). Occ: 2 RCS, 8 RS. Cargo: 900 cf.

External: 300 sf solar cells. Statistics Size: 240'x30'x20' Payload: 224 tons Lwt.: 254 tons Volume: 50,000 cf Maint.: 12 man-hours Price: $93,691,600 HT: 7.

Glide Ratio 43:1. Design Notes Finely made. Body is 50,000 cf, with lifting body and radical streamlining. Wheels are 2,500 cf, retract into body. Structure is extra-light and advanced. Armor is advanced, fireproof ablative on body, advanced composite on wheels. Sealed. Computerized controls with duplicate maneuver controls. There are 270.61 cf of empty space. Empty weight is 60,000 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.
