Objectif
It is accepted that space debris will increase in the next
decades despite any considerable effort made to limit their generation.
Debris of more than 10cm can be avoided by the satellites and also the
very small particles of less than 0.1cm are taken into account in the
current designs. The debris from 0.1 to 10cm is however not predictable,
not taken into account today and could severely damage a spacecraft. The
probability of damage by such particles could reach an unacceptable level
thus creating a new paradigm for LEO satellites. A better protection of
space systems against damage caused by debris collision is the aim of the
ReVuS study, articulated around 4 lines: - To restore the existing models
and works for the prediction and the knowledge of damage assessment (LDEF,
SS, Colombus…). - To assess the solutions At system level, with
distributed/fractionated architectures, or by using active detection and
mitigation strategies. On the satellite exterior, by defining and testing
new shielding materials derived from ground markets In the satellite
interior , by editing new rules of harness routing & equipment
configuration - Resilience analysis, evaluating the proposed solutions
& generating recommendations/design rules. Assess possible
standardisation. - To dispatch the results to the space community. METOP
and a Radar satellite will be used as a guiding principle for all the
analysis The consortium led by Astrium Satellites gathers all expertise
required. The Ernst-Mach-Institut (EMI Fraunhoffer), the universities of
Surrey, Southampton & Braunschweig will provide the background
knowledge and models. The shielding materials will be defined by TenCate
Advanced Composites, and tested in the EMI facilities. The users will
participate in the analysis. HisCox will represent the insurer of the
satellite. The dissemination of the results will be ensured by Astri
