H2020 EDDA is one of the project of the Strategic Research Cluster (SRC) on “In-Space electrical propulsion and station keeping” (http://epic-src.eu/) and also a continuation of H2020 HV-EPSA (grant 687515, http://hv-epsa-h2020.eu/) which allowed to work on high voltage bus, from 300V to 600V, mandatory for direct-drive architecture.
H2020 CHEOPS (also, https://www.cheops-h2020.eu/) is developing Electrical Propulsion Subsystem for various power range missions, including a high-power Hall Effect Thruster (HET) of 20kW. A dedicated assessment is done for a direct-drive architecture for a specific HET called HT20k.
Hall Effect Thruster, as well as HEMP Thruster (in H2020 HEMPT-NG, part of theSRC, https://www.hempt-ng.eu/) has a voltage range compatible to the high voltage bus studied in HV-EPSA H2020 EDDA will enable a transversal architecture compatible with various electric thrusters available on the market, allowing to enhance the global efficiency from solar array to thruster
Numerous missions will benefit
