The transition from old space to new along with increasing commercialization has a major impact on flight, in general, and electric propulsion (EP) by ion thrusters, particular. Ion thrusters are nowadays used as primary systems space. This article describes how these changes related affect various aspects that important for the development of EP systems. Starting historical overview flight technology systems, number missions underlying technologies presented. focus our discussion is radio...
Abstract The H2020 MINOTOR project focused on the study and optimization of ECRA thruster, an electric propulsion system for satellites. First, a 30 W prototype this Electron Cyclotron Resonance Thruster (ECRT) is optimized. Then, 200 design based these findings. performances both prototypes were assessed at two different facilities: ONERA in France Justus Liebig University Germany. Significant improvement thrusters with decrease background pressure presented. Total thrust efficiencies as...
A key parameter when characterizing the performance of an electric propulsion system is obviously its thrust. The thrust can be either determined directly using a so-called balance or deduced from indirect measurements. Here, we present comparison measurements same radio frequency ion thruster in range 250 μN to 1.5 mN three different approaches: conventional direct measurement employing and two measurements, one based on force probe located stationary thruster’s plume conjunction with scan...
