NASA put the squeeze on a large rocket test section today. Results from this structural strength test at NASA's Marshall Space Flight Center in Huntsville, Ala., will help future heavy-lift launch vehicles weigh less and reduce development costs.
This trailblazing project is examining the safety margins needed in the design of future, large launch vehicle structures. Test results will be used to develop and validate structural analysis models and generate new "shell-buckling knockdown factors" -- complex engineering design standards essential to launch vehicle design.
