    A unique approach to fabricating precision space structures elements (1981)
    In:  Other Sources
    Details
    Publication Date: 2019-07-13
    Description: A procedure of fabricating graphite epoxy columns used in the assembly of large space platforms is described. The requirement for precise dimensional control led to a unique hot resin injection process. Dry, high modulus fiber is wound over a vertically mounted steam-heated mandrel. A steam-heated sleeve or caul is slipped over the wound mandrel and resin is injected and cured in place. Approximately 200 column elements have been fabricated using this efficient process.

    A concept for high speed assembly of erectable space platforms (1981)
    In:  Other Sources
    Details
    Publication Date: 2019-07-13
    Description: A simple, fully automatic assembler associated with the on-orbit assembly of tetrahedral truss platforms erected of graphite epoxy tapered columns is described. The assembler, which can operate either as a free flyer or attached to the Orbiter, is capable of constructing a platform from a full load of truss columns and node joints in 36 hours. The geometry of this electrically-driven machine is based on a compound parallelogram system which permits backward as well as lateral translations. Concepts have been developed for half-column assembly as well as for column and node joint insertion into the platform.
