The results and observation are summarized of flywheel spin tests conducted in the Oak Ridge Flywheel Evaluation Laboratory for the Mechanical Energy Storage Technology project at the Lawrence Livermore National Laboratory (LLNL). Two types of tests are discussed. The first is an ultimate speed test similar to those performed in FY 1980. It includes ultimate speed evaluations for a tapered, quasi-isotropic, graphite composite flywheel built by LLNL, a constant thickness disk with an SMC core and circumferentially wound graphite restraining ring built by Owens-Corning Fiberglas and Lord Kinematic Corporation, and a constant thickness disk with an S-glass, ..cap alpha..-ply layup core and circumferentially wound graphite ring built by General Electric. The second type of test is a cyclic fatigue test. A matching General Electric flywheel was used as the first test unit. Test results as well as general observations and conclusions are presented.
