AbstractThere is high possibility that space debris impacts to a solar array paddle in spacecraft parts, because the solar array paddle has large area. Space debris impact to the solar array causes not only mechanical damage but also electrical damage such as arcing on the solar array through local high density plasma created by hypervelocity impact. In the worst case, Joule heating of this arcing carbonizes insulation layer and permanent short-circuit path is created. This is permanent sustained arc. However, no permanent sustained arc caused by space debris impact in orbit has been reported. Purpose of this study is evaluation of possibility of permanent sustained arc through the plasma created by debris impact. Hypervelocity impact tests to solar array coupons in the condition of pseudo power generation were conducted. We ascertained that space debris impact can lead to permanent sustained arc on the solar array due to plasma created by hypervelocity impact.
