An experimental impact simulation is currently performed with respect to Columbus hull components. The man objectives are to establish a data base for an optimum design of meteoroid/debris protection shields (MDPS) as weil as viewport components, and to obtain input data for numerical models which describe the penetration and perforation processes of meteoroid bumper and viewport systems. As expected, it has been experimentally demonstrated that protection against particles in the order of 1 cm, at relatively low impact (around 3 km/s), is extremely problematic. Applying usual dual-plate Al bumper techniques would require unrealistically thick and heavy systems in order for safely stop such particles, which are eypected to occur within the low earth orbit space debris complex. Preliminary results obtained with multiplate Al targets as well as hybrid target systems (Al-ceramics, Al-Kevlar) indicate that the situation can be considerably improved with respect to the shielding efficiency at a given areal material density. These investigations are still progress. Results of the test series performed with Al dual-plate systems and with laminated glass targets as viewport components are reported and discussed.
