Pulsed Plasma Propulsion Technology.

Abstract : An engineering prototype pulsed plasma propulsion system delivering lmlb (4.45mN) of thrust at a specific impulse of 1794s and having a total impulse capability of 38,284 lb-s (166,OONs) has been designed and completely fabricated. The thrust efficiency is 31.5% and the overall system efficiency is 25.3%. The system, including structure, capacitors, breadboard power converter and propellant weighs 50.23lb (22.8kg).
