It was the purpose of this project to provide the tools which allow efficiency comparisons between fuze related two and three pass step-up gear trains of different tooth geometries which are subject to operation in a spin environment. To this end mathematical models of such gear trains with both involute and ogival tooth shapes have been developed. These models allow, by way of moment input-output relationships, the determination of point and cycle efficiencies of the gear trains. Pivot friction, partly due to the centrifugal forces, is considered in addition to tooth contact friction. All models allow a wide variety of parameter changes. The appendices of this final report contain the derivations for the moment input-output relationships.
