Abstract
* The performance of a 3-cm-long capillary-fed colloid thruster is measured as a function of temperature and capillary channel width. The data are complementary to the large body of data available on the performance of pressure-fed thrasters. Propellant mass flow rate and thrust change considerably as temperature is increased over the range 19-40°C, but efficiency does not show any significant change. To obtain high-exhaust velocity and high-mean specific charge the propellant temperature should be as low as possible. At constant temperature, propellant mass flow rate is proportional to the square of capillary channel width. If the thruster is operated at high-current levels, sudden drops in thruster efficiency may occur because of a hydrodynamic effect.
