Abstract:

The program is directed towards obtaining a greatly improved understanding of the physical factors which govern high current brush performance, leading to the development and demonstration of advanced brush materials. These materials are to be demonstrated at 7.75 MAsq in. 5 kAsq in. in a machine application as the ultimate goal of the program. Progress is reported in the attainment of this goal in the areas of materials characterization, brushring dynamics, brush heat transfer, atmosphere control, contact interface investigations, multi-element brush research, and monolithic brush material research. The participation of university researchers in the investigation of specific technology areas is also described.
