DOI: 10.2514/1.31101 This study investigates emissive properties as a function of time and temperature of niobium and tantalum, for which the surfaces have been altered by an arc-texturing technique. To date, space radiators achieve relatively high e

In order to test the performance of thrusters using radio-frequency (RF) electrical propulsion in the micronewton range, a thrust stand must be calibrated to accurately measure these thrusts. Confounding effects arise from the heating of power cables

A prototype RF plasma micro-thruster has been investigated numerically and experimentally. The experimental results were obtained on a thrust stand capable of micro-Newton resolution. Thrust and mass flow (hence specific impulse) were measured for an

The pulsed inductive thruster has shown promise as a high power, high specific impulse electric propulsion engine. As ingenious as the existing pulsed inductive thruster designs are they still contain drawbacks, most notably the complicated drive coi
