Pericyclic transmission prototype: Detailed component design, analysis, and fabrication

Based on component level and system level design analysis tools developed in the past years, an internally-driven torque sharing, twin configuration, Pericyclic drive concept has been developed to operate within allowable operating conditions of the NASA Glenn Transmission Test rig. In this work, design refinements and additional features required for successful fabrication, assembly, and testing of the prototype transmission are described. Thereafter, the weights and inertia of the components are updated in the design analysis to predict performance characteristics of the test article such as efficiency, bearing loads and life, tooth loads, lubrication requirements, and component stiffness. Some of these results will be validated from test runs of the prototype scheduled for near future. The current status of design and fabrication of rotating and static components is also reported.
