Research and Development History of Glass Bubbles Bulk-Fill Thermal Insulation Systems for Large-Scale Cryogenic Liquid Hydrogen Storage Tanks

Based on the published literature record, this document provides an overview of the research and development of glass bubbles bulk-fill thermal insulation systems for cryogenic equipment in general and, in particular, for large-scale cryogenic liquid hydrogen (LH2) storage spheres. Glass bubbles (also known as hollow glass microspheres) are used in place of perlite powder which began use in double-wall cryogenic tanks in the 1930s. Included in this overview is a historical summary, a development timeline, a selected publications list, and the key technical points from those publications.

Space Shuttle Orbiter-External Tank Forward Bipod Loads Analysis

The forward bipod system provides a robust attachment between the Space Shuttle Orbiter and the External Tank. Closed-form analyses were performed to determine how much additional load-carrying capability exists in this system beyond the current certified load limits. Results of these analyses suggest that the forward bipod system is capable of carrying loads that are at least 25 percent greater than the current flight limit loads, and possibly even more if lower safety factors are allowed. The forward bipod system may also have additional load-carrying capabilities, given the conservative nature of these analyses.
