Preliminary study on sustained arc due to plasma excited by hypervelocity impact of space debris on the solar array coupon

摘要: Recently, solar array has become higher in potential and larger capacitance. Therefore, possibility of collision between space debris enlarged been pointed out. Many dust impacts were confirmed on fuselage the retrieved satellite flyer unit (SFU) paddle Eureca. If collides with an orbiting satellite, it may cause generation high-density plasma by impact-induced dielectric breakdown component phenomenon called discharge. This discharge short circuits current will not flow into pay load satellite. And very worst event this is operational end However, any events impact cannot be yet confirmed. But we ignore such impact. The purpose present paper to investigate condition due which yields us reduction electric power array, reduce influence missions. In study, a coupon was tested under hypervelocity projectile launched two-stage light gas gun installed Kyushu Institute Technology (KIT). As result, verified ground test.
