NASA Johnson Space Center Houston TX USA Abstract: In this work, hypervelocity impact tests up to 7 km s are used to compare the performance of Whipple shields integrated with layers of metallic glasses with a baseline target analogue of one of the shields similar to what is used on the International Space Station. The baseline target failed under the impact while the target utilizing metallic glass as a replacement for the fabric layers in the baseline passed the test. The paper postulates on the prospects of future implementation of metallic glasses as spacecraft debris shields.

متن کاملHypervelocity Impact on Rock
Concerted research efforts are being made to find new means of rock disintegration for more rapid, efficient excavation. Water jets, metallic jets and hypervelocity projectiles have been found to cut or break rock with varying degrees of efficiency depending upon several parameters, which are being defined by research in Russia, Britain and the United States. Optimum performance of high velocit...
متن کاملThe dynamic compressive behavior of beryllium bearing bulk metallic glasses
In 1993, a new beryllium bearing bulk metallic glass with the nominal composition of Zr41.25Ti13.75Cu12.5Ni10Be22.5 was discovered at Caltech. This metallic glass can be cast as cylindrical rods as large as 16 mm in diameter, which permitted specimens to be fabricated with geometries suitable for dynamic testing. For the first time, the dynamic compressive yield behavior of a metallic glass was...

Well known Ashcroft’s...
متن کاملDoes Laser Ablation Vapor Simulate Impact Vapor?
Introduction: Many laser experiments have been done to simulate hypervelocity impact vaporization [e.g., 15]. Laser simulation has a number of advantages. It can create high-temperature plumes with high repeatability and a high repetition cycle at a relatively low cost. Furthermore, because laser light can penetrate through a glass window (if chosen properly), the target material and vaporizati...
