| Résumé : |
As part of the Space Technology Game Changing Development Program (GCDP) Composite Cryotank Technology Development (CCTD) contract, Boeing fabricated a 2.4 m diameter test article as a precursor to a 5.5 meter cryotank design, fabrication, and test. This component encompasses several challenging design features: (a) one-piece co-cured/co-bonded spherical geometry with integral skirts, (b) out-of-autoclave curing materials, (c) permeation resistant thin/hybrid ply laminate skins, and (d) thin and thick off-angle slit tape (tow) construction. The component was built on a 24 piece collapsible composite tool using robotic fiber placement. This paper details the tooling and manufacturing flow with an emphasis on process development building block activities. Cessons leamed are compiled that will be used to help guide the build of a 5.5 m diameter tank during the next phase of the CCTD contract. |
