ABSTRACT:
Future NASA long duration missions will require high performance, reliable, longlived mechanical moving systems. In order to develop these systems, high technology components, such as bearings, gears, seals, lubricants, etc., will need to be utilized. There has been concern in the NASA community that the current technology level in these mechanical component/tribology areas may not be adequate to meet the goals of long duration NASA missions such as SEI. To resolve this concern, Lewis Research Center sent a questionnaire to government and industry workers (who have been involved in space mechanism research, design, and implementation) to ask their opinion if the current space mechanisms technology (mechanical components/tribology) is adequate to meet future NASA Missions needs and goals. In addition, a working group consisting of members from each NASA Center, DOD and DOE has been established to investigate the technology status. This paper summarizes the results of the survey and conclusions of the working group.
