Kurzfassung
Space, Germany Since 2009 Airbus DS Space Systems, Friedrichshafen, has been investigating Electric Propulsion (EP) systems for high precision attitude and position control of spacecrafts. As a start, an experimental measurement campaign to demonstrate the feasibility of down scaling the High Efficiency Multistage Plasma Thruster (HEMPT), developed by Thales at Ulm in Germany, to the micro-Newton thrust level was initiated in close cooperation with university research groups. The HEMPT is potentially an attractive micro-Newton thruster concept because of the unique advantages of the HEMPT principle, e.g. nearly erosion-free operation and simple system and interface design with just one high voltage supply and one mass flow controller. We designed a next generation μHEMPT with a thrust range between 50 μN to 500 μN, a specific inpuls of more than 2000 s, a divergence efficiency of more than 80% and a mass efficiency of around 70% . The proceeding will wrap up the thruster design and key parameters of the thruster and the performed measurements will be summarised
