Positron Aerospace Propulsion
Introduction
Antimatter is considered an extremely attractive fuel for aerospace propulsion
because of its enormous advantage in energy density over all other known
sources of energy. However, because antimatter does not occur naturally and
is unstable in the presence of matter, no vehicles have ever flown using it.
After a short overview of the various aerospace applications of antimatter, this
paper provides a detailed analysis of air-breathing turbojets and turbo-ramjet
missiles, as well as rockets for manned interplanetary missions. It discusses
new methods of producing and storing large numbers of antielectrons, or
positrons, and compares their costs with those of antiprotons. Finally, the
paper considers the prospects for the first, modest demonstration of positron
propulsive flight within the next 10 years. Interplanetary missions on
positron-propel…
