Though partially funded by NASA, it is still a private site. Therefore, before downloading any materials for use, you need to ask permission. Basic programs address the needs of both the Army and NASA Lewis by concentrating on advancing gear technology for a wide variety of uses that require in-depth knowledge and precision.
Emphasis is on aeronautical applications - in particular, helicopter transmissions.
All aspects of analytical and experimental research are pursued, including disciplines related to details of gear-tooth shapes and types of geometries, materials, thermal behavior, lubrication, noise and vibration, and manufacturing methods. The analytical portion is accomplished through both in-house and university grant efforts. The computer codes developed as a result of the analytical research are distributed to industry for their use in gear analysis and design. As an important part of the process, NASA Lewis has provided unique facilities for this experimental research. Spur and bevel gear component test rigs are used to conduct fatigue testing, evaluate candidate materials, compare lubricants and to evaluate and develop vibration diagnostics techniques.
