Despite their cost-saving advantages, electric propulsion devices may raise several issues, such as the erosion and contamination of surrounding surfaces by the highly energetic ions expelled from the thrusters. To date, little data is available concerning the erosion and contamination of space-specific materials such as Kapton®, paints, or glasses. The purpose of the test campaign carried out in 2001/2002 at ONERA is thus to provide those missing data. Indeed, erosion tests allowed to determine the sputter yields of space materials as a function of ions energy and incidence; contamination tests allowed to correlate the erosion measurements; whereas thermo-optical characterisations allowed to quantify the effect of erosion and contamination on the thermal properties. Since Astrium designs spacecraft embarking electric propulsion, it has been deeply involved in this test campaign. Astrium's PPS modelling tool has then highly benefited from the erosion and contamination test results: improvement of the sputter database, correlation of contamination models, assessment of system impact of erosion and contamination. All this provides Astrium with a very reliable PPS modelling tool, thus resulting in reduced margins for the design of satellites embarking electric propulsion devices.
