Abstract:

The MPD arcjet program at EOS is aimed at developing the technology of electric thrustors capable of performing efficiently 40-60 conversion of electrical power to beam power for extended periods of time up to 100 hours in the specific impulse range of 1500-5000 seconds, at power levels of 10-100 kilowatts. The analytical results are presented for each of the significant mechanisms. Progress in the experimental portion of the program has included the following The thrustor has been operated continuously for 100 hours with no significant electrode erosion A novel gas-actuated feed system which had been designed during the previous reporting period was fabricated, tested and calibrated Test runs were made using ammonia as propellant Tests with a three- magnet configuration resulted in performance inferior to that obtained with the two-magnet thrustor.
