Development and Characterization of High-Efficiency, High-Specific Impulse Xenon Hall Thrusters
Development and Characterization of High-Efficiency, High-Specific Impulse Xenon Hall Thrusters by Richard Robert Hofer Chair: Associate Professor Alec D. Gallimore This dissertation presents research aimed at extending the efficient operation of 1600 s specific impulse Hall thruster technology to the 2000-3000 s range. While recent studies of commercially developed Hall thrusters demonstrated ...
متن کاملEfficiency Analysis of a High-Specific Impulse Hall Thruster
Performance and plasma measurements of the high-specific impulse NASA-173Mv2 Hall thruster were analyzed using a phenomenological performance model that accounts for a partially-ionized plasma containing multiply-charged ions. Between discharge voltages of 300-900 V, the results showed that although the net decrease of efficiency due to multiplycharged ions was only 1.5-3.0%, the effects of mul...
متن کامل2 D simulations of Hall thrusters
Closed-Drift (Hall) thrusters constitute an important electric propulsion technology for certain applications requiring low thrust levels, e.g. satellite station keeping and orbit transfer (Gulczinski and Spores, 1996). The thrust in Hall thrusters is generated by ions being accelerated through an annular plasma by the electric field set up between an anode and a cathode. This electric field is...
متن کاملLarge Carbon-Carbon Grids for High Power, High Specific Impulse Ion Thrusters
NASA is investigating high power, high specific impulse propulsion technologies that could enable ambitious flights such as multi-body rendezvous missions, outer planet orbiters and interstellar precursor missions. Ion engines can efficiently operate at very high specific impulse, but accelerating voltages of many kV result in greater ion optics wear rates due to high energy ion bombardment. Th...
متن کاملMultiscale Modeling of Hall Thrusters
Multiscale Modeling of Hall Thrusters Hall thrusters are efficient space propulsion devices that produce thrust by accelerating quasineutral plasma. The thruster consists of a channel with one end open to the ambient environment. The neutral propellant is injected at the closed end and is ionized by electrons produced by an externally mounted cathode. A radial magnetic field is applied across t...
