Abstract

For the hypervelocity impact simulation of micrometeoroids on a space station, a plasma accelerator was constructed and tested to achieve projectile velocity of 10 km/s. Then the morphology of craters on an aluminum alloy target was investigated. The dual element shield structure consisting of aluminum alloy was tested up to 5 km/s impact. The morphology of impact area and the new technique of projectile emission was also reported.
