[38]Fusion propulsion if Bussard IEC fusion works

   [39]Work is continuing towards Robert Bussard's vision of inertial
   electrostatic fusion.
   UPDATE: Tom Ligon wrote the slides and gave the speech which presented
   this material.
   Fusion R&D
   Phase 1 - Validate and Review WB-6 Results
   The proposed WB-7 and WB-8 devices will be constructed and tested
   during 2008.
   1.5 - 2 years (by the end of 2008), $3-5M
   Fusion R&D
   Phase 2 - Design, Build and Test
   Full Scale 100 MW Fusion System
   5 years (2009-2013), $200M
   If the full commercial system is successful then from 2014-2029+ there
   would the development of nuclear fusion enabled space vehicles.
   bussard fusion space plane
   Two 8 gigawatt Thermal fusion engines power this vehicle. The cost
   estimate is 100 times less than the best system available now.
   bussard fusion lunar lander
   20 hours to go from the low earth orbit to lunar orbit. 24 hours to go
   from the earth surface to the lunar surface using these systems.
   [2050150085_3c89f17349.jpg?v=0]
   These vehicles would have three main types of fusion engines. The DFP,
   CSR (controlled space radiator) and ARC which are shown with different
   ISP and thrust levels. CSR and ARC are Quiet Electric Discharge (QED)
   engines with ISP in the 1500 to 70000 range. They use arcjet heating
   of reaction mass.
   DFP are diluted fusion product engines. They have high ISP 50,000 to
   1.2 million. Reaction mass added to fusion product directly from the
   reactor.
   QED fusion space engines types
   Here are block diagrams of the QED engine types
   long range space vehicle sizing with the different engine types
   Here are long range space vehicle sizing with the different engine
   types. The Bussard rockets are about 1 to 2 football fields long.
   description of Mars Bussard fusion vehicle
   Description of Mars Bussard fusion vehicle. 33-38 days to Mars one
   way.
   Description of a vehicle to go to Saturn's moon Titan

   diluted fusion product engine schematic
   Diluted fusion product (DFP) engine schematic
   fusion rocket schematic for Titan mission
   Fusion rocket schematic for Titan mission. Each way would take 75-90
   days.
   The vehicles will enable large and inexpensive space colonies.
   Lunar colony
   4000 people, 25 tons each, $12.5 billion (1997 estimate)
   Mars colony
   1200 people, 50 tons each, $15.6 billion
   Titan colony
   400 people, 60 tons each, $16.2 billion
   [2050150097_67e7517f33.jpg?v=0]
   Why the colonies and vehicles are relatively cheap
   If we have the relatively lightweight working fusion reactors with
   power ranges up to 10 gigawatts or more each, then all sorts of space
   propulsion becomes possible.
   The fusion reactors could power [40]massive laser arrays or high
   powered [41]minimag Orion style propulsion systems.
   If the Bussard inertial electrostatic fusion reactors work out we
   would redesign everything. All of the navy and military vehicles and
   our entire civilization. Even these first designs would give flights
   to the moon and orbit equal to about the price of old Concorde
   airplane tickets.
