Based on the favorable results of recent parallel studies by General Electric and Garrett/AiResearch, UMTA has proceeded to implement the development of engineering prototype flywheel propulsion systems for urban transit coaches. Parallel contracts for the development of competititve prototypes have been awarded, with General Electric using a steel flywheel and Garrett a flywheel composite material. System design and fabrication will be followed by comprehensive laboratory tests, and each prototype will subsequently be installed in an urban transit coach for field test and evaluation in both a pure flywheel and a flywheel/trolley coach hybrid mode. When operating off the flywheel, the coach will have a range of 3.5 miles between flywheel charges with all auxiliary systems operating, and 8 miles with minimum auxiliary loads. Flywheel charging is accomplished though automatic power collectros that engage a wayside DC source at terminal and transfer pints or under wire when operating as a trolley coach. Advantages of the system include reduced energy consumption through recuperation of braking energy, independence from petroleum fuels, and minimized noise and pollution. Satisfactory demonstration of performance by the prototypes would be followed by deployment of several vehicles of each type in revenue service. (Wassmann)
