Flywheel-Powered Shuttle Car.

PB91200543

Publication Date	1991
Personal Author	Bartels, J. R.; Mayercheck, W. D.; Hummer, J. A.
Page Count	43
Abstract	The report describes the development, system-by-system evaluation, and preliminary surface testing of a flywheel-powered shuttle car. The use of a self-contained flywheel power source has the potential to eliminate the numerous safety and routing problems associated with tethered mobile equipment. An alternative to conventional power cable systems was developed consisting of the world's first seven-rotor stacked-flywheel system capable of storing 6 kW h of energy at 16,700 rpm. Numerous interdependent systems were necessary for successful interfacing with a conventional shuttle car. Each system was evaluated and tested individually. Finally, the entire shuttle car was surface-tested. The tests indicated that the flywheel energy system can function and operate a shuttle car. The economics of the system and the design of required support systems were not addressed in the project.
