Ionization Efficiency in Electric Propulsion Devices

  title={Ionization Efficiency in Electric Propulsion Devices},
  author={Jerry L. Ross and Lyon B. King},
While it is widely known that propellant ionization represents an energy loss mechanism that acts to decrease the efficiency of electric propulsion devices, it is not apparent how or where this loss can be measured in thruster data. Furthermore, the manner in which the propellant is ionized holds potential inefficiencies (power losses) above and beyond those arising from the ionization potential. This paper presents a simplified phenomenological model that sheds light on how the ionization…

Thrust Efficiency, Energy Efficiency, and the Role of VDF in Hall Thruster Performance Analysis (Postprint)

Abstract : A rocket power efficiency equation was written to explicitly account for the effect of the velocity distribution function (VDF) of the propellant jet on the conversion of anode electrical

Investigation of Low Voltage/High Thrust Hall Thruster Operation

Performance of low-power and high-power Hall thrusters were experimentally investigated at discharge voltages from 100–150 volts. Discharge efficiencies dropped significantly as discharge voltage was

Energetics of Propellant Options for High-Power Hall Thrusters

An emerging hurdle in high-power Hall thruster development has been the use of Xenon as the propellant of choice. While Xenon has several advantages as a propellant, namely low ionization energy,
