Pulsed Plasma Technology in Microthrusters

摘要: The report describes the pertinent results of the studies carried out in advancing solid propellant pulsed plasma microthruster system technology in the thrust range from below 1 micropound up to roughly 200 micropounds and encompassing the system specific impulse range up to 2400 seconds. Thruster nozzles have been operated up to 3800 hours at the 50 micropound thrust level. Complete thruster systems have been operated up to 630 hours at the 140 micropound thrust level 317 lb-sec of total impulse. A thrust stand capable of …
