Harmonic Drives used for many applications. No facilities and very little technology research being conducted in space drive area. How do we qualify and how much qualification is necessary. There is a need to develop accelerated life test techniques and scale factors that people can believe in. Space Station Need improved bearings, lubricants and gears.
Type is dependent on application.
Manned missions to Mars. Need improved bearings, lubricants and gears. Type is dependent on the application. Shuttle flights to space station. Cryogenic propulsion issues.
