This report documents the objectives, major tasks and approaches of the research Project, and the progress made over the three year span of the effort. The primary objective is presented as being the search for understanding of and analytical simulation capability for the effects of flexibility and configuration evolution on the on-orbit dynamics and stability of orbiting spacecraft. The approach is described in terms of the modeling and analysis of isolated deployment and assembly mechanisms, the modeling and analysis of coupled orbital-attitude-vibration dynamics of orbiting spacecraft, and the integration of the two for on-orbit system performance simulation. Details of the modeling and analysis efforts are described and sample results obtained during the scourse of the research are presented and discussed.
