A study of AL-bumper thickness effect on damage of Whipple shield by hypervelocity impact of AL-spheres

Hypervelocity impacts on spacecraft in low earth orbit by meteoroids and space debris posed a threat to space missions. All spacecraft in low earth orbit are subject to hypervelocity impacts by meteoroids and space debris. These impacts can damage flight-critical systems, which can in turn lead to catastrophic failure of the spacecraft. Therefore, the design of spacecraft for an earth–orbiting mission must take into account the possibility of such impacts and their effects on spacecraft structure. So, investigation into the impact damage characteristics has become an important problem for spacecraft protection designing.
