Exploring New Concepts Towards Multi-Mode Low-Power Robust Electric Propulsion

Abstract

George Washington University developed multi-mode low-power electric propulsion. In particular high thrust to power ratio and efficiency in low power regimes were achieved. This work resulted in development a new device for CubeSatellite propulsion called two-stage micro-cathode arc thruster. Being magnetized by an axially symmetric dc magnetic field, the vacuum arc discharge demonstrates a threshold behavior: parameters such as thrust and the thrust-to-power ratio rapidly jump after a certain dc voltage. It is demonstrated that such an effect improves the thrust, efficiency (about 50 percent), and thrust-to-power ratio.
