"The QED Engine System: Direct Electric Fusion-Powered Systems for |
Aerospace Flight Propulsion" by Robert W. Bussard, EMC2-1190-03, |
available from Energy/Matter Conversion Corp., 9100 A. Center |
Street, Manassas, VA 22110. |
[This is an introduction to the application of Bussard's version |
of the Farnsworth/Hirsch electrostatic confinement fusion |
technology to propulsion. 1500<Isp<5000 sec. Farnsworth/Hirsch |
demonstrated a 10**10 neutron flux with their device back in |
1969 but it was dropped when panic ensued over the surprising |
stability of the Soviet Tokamak. Hirsch, responsible for the |
panic, has recently recanted and is back working on QED. -- Jim |
Bowery] |
"PLASMAKtm Star Power for Energy Intensive Space Applications", by |
Paul M. Koloc, Eight ANS Topical Meeting on Technology of Fusion |
Energy, special issue FUSION TECHNOLOGY, March 1989. |
Aneutronic energy (fusion with little or negligible neutron |
flux) requires plasma pressures and stable confinement times |
larger than can be delivered by current approaches. If plasma |
pressures appropriate to burn times on the order of milliseconds |
could be achieved in aneutronic fuels, then high power densities |
and very compact, realtively clean burning engines for space and |
other special applications would be at hand. The PLASMAKtm |
innovation will make this possible; its unique pressure |
efficient structure, exceptional stability, fluid-mechanically |
compressible Mantle and direct inductive MHD electric power |
conversion advantages are described. Peak burn densities of tens |
of megawats per cc give it compactness even in the |
multi-gigawatt electric output size. Engineering advantages |
indicate a rapid development schedule at very modest cost. [I |
strongly recommend that people take this guy seriously. Bob |
Hirsch, the primary proponent of the Tokamak, has recently |
declared Koloc's PLASMAKtm precursor, the spheromak, to be one |
of 3 promising fusion technologies that should be pursued rather |
than Tokamak. Aside from the preceeding appeal to authority, the |
PLASMAKtm looks like it finally models ball-lightning with solid |
MHD physics. -- Jim Bowery] |
Retrieve files pub/SPACE/SPACELINK/6.5.2.* from the Ames SPACE |
archive; these deal with many aspects of ion drives and describe the |
SERT I and II missions, which flight-tested cesium ion thrusters in |
the 1960s and 70s. There are numerous references. |
IEEE Transactions on Magnetics (for example, v. 27 no. 1, January |
1991 issue). Every so often they publish the proceedings of the |
Symposium on Electromagnetic Launcher Technology, including hundreds |
of papers on the subject. It's a good look at the state of the art, |
though perhaps not a good tutorial for beginners. Anybody know some |
good review papers? |

can change its velocity by up to slightly less than 1 km/sec. if |
it is travelling under that velocity wrt a suitable asteroid. |
"Alternate Propulsion Energy Sources", Robert Forward |
NTIS AD-B088 771/1 PC A07/MF A01 Dec 83 138p |
Keywords: Propulsion energy, metastable helium, free-radical |
hydrogen, solar pumped (sic) plasmas, antiproton annihiliation, |
ionospheric lasers, solar sails, perforated sails, microwave |
sails, quantum fluctuations, antimatter rockets... It's a wide, |
if not deep, look at exotic energy sources which might be useful |
for space propulsion. It also considers various kinds of laser |
propulsion, metallic hydrogen, tethers, and unconventional |
nuclear propulsion. The bibliographic information, pointing to |
the research on all this stuff, belongs on every daydreamer's |
shelf. |
