NASA Crush Test
Engineers at NASA’s Marshall Space Flight Center applied almost 1 million lb. of force to crush a 20-ft.-tall aluminum lithium cylinder in a test-to-failure designed to update engineering data generated in the Apollo era. A follow-on to tests with smaller articles, the large-scale trial aims to generate shell-buckling knockdown factors that can be used to build the new heavy-lift launch vehicle Congress wants, with lighter structures based on modern materials and manufacturing processes that are still strong enough to withstand launch loads.
