The final report presents an analysis defining the operational characteristics and potential load capacity of the nutating mechanical transmission NMT concept. Since a fully operational NMT capable of any substantial loading has not been constructed, the scope of this program has been largely analytical. Substantial technology has been borrowed from the gear and bearing fields to provide a sound basis for the derivation of some aspects of the analysis. To provide a clear, concise description of the NMT and its applications, limitations, and benefits, the main body of this report presents equations derived as required. For completeness, the full analysis including applicable equations, figures, etc. is presented as an appendix. Capsule summaries in the form of narrative figures are used throughout the main body of the report to highlight key topics.
