21 HEMP 3050 Ion Thrusters A new thruster concept has verified its potential for LEO, MEO and GEO satellites and scientific mission applications: orbit topping, north/south station keeping (NSSK), drag compensation, repositioning, de-orbiting of small (0.5 t) to large (10 t) satellites, deep space cruising. Thrust & power range: 1 mn to 80 mn at 20 W to 2 kw with Specific Impulse 1500 s to 3000 s (exhaust velocity: 15 to 30 km/s) 80% to 90% of propellant mass saving compared to chemical thrusters Reliable and long life operation due to magnetic plasma confinement: Erosion free operation for more than h or a total impulse of more than Ns. Light bulb like turn on & turn off procedures allowing automatic attitude and orbit control (AOCS) routines similar to chemical thrusters. Clustering of modular thrusters: Allows thust vectoring and avoids a mechanical gimbal mechanism (cost cutting). Simple power supply and flow control unit interfaces: 50% cost cutting possible compared to standard Hall Effect EP system. 21
