Effects of propellant temperature on fragmentation in the plume of a porous electrospray thruster
Effects of propellant temperature on fragmentation in the plume of a porous electrospray thruster
A Porous Electrospray Thruster which uses a heater is presented. Three sets of tests are undertaken on the thruster: Current-Voltage-Temperature , Plume Angle Analysis and Retarding Potential Analysis at a voltage range of 2.20kV to 3.50kV and a temperature range of 25°C to 100°C. Current is found to increase with voltage and temperature, ranging from 3.9μA to -5.9μA. The plume angle is found to vary between 10° and 20° and remain unchanged through testing. Retarding Potential Analysis shows the proportion of the current accelerated to the maximum potential increases with temperature and decreases with voltage. Furthermore,a higher proportion of the current is accelerated to maximum potential at 60°C than at any other temperature.

Abstract
A Porous Electrospray Thruster which uses a heater is presented. Three sets of tests are undertaken on the thruster: Current-Voltage-Temperature , Plume Angle Analysis and Retarding Potential Analysis at a voltage range of 2.20kV to 3.50kV and a temperature range of 25°C to 100°C. Current is found to increase with voltage and temperature, ranging from 3.9μA to -5.9μA. The plume angle is found to vary between 10° and 20° and remain unchanged through testing. Retarding Potential Analysis shows the proportion of the current accelerated to the maximum potential increases with temperature and decreases with voltage. Furthermore,a higher proportion of the current is accelerated to maximum potential at 60°C than at any other temperature.
