The level of damage imparted on three types of satellites components resulting from hypervelocity impacts of aluminum projectiles onto a neighboring structural part have been assessed experimentally by using a double stage light gas gun. The experimental configurations were designed to simulate debris encounters with a space vehicle during its operational life time around the Earth. The first test was conducted against a set of separate harness strapped down on the inner surface of a carbon facesheet sandwich panel in order to assess the effectiveness of redundant cables spacing in case of unitary debris perforating impact onto the structure. The resistance to damaging of a silicon carbide mirror and a solar panel was then evaluated against debris cloud generated by prior impact of chunky debris with the satellite structure. Potential losses of electrical functional capabilities were then derived. The vulnerability/Survivability Pléiades software was updated accordingly.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
