Fabrication of two one-fifth scale fiber composite flywheels. Final report

Technical Report · Tue Apr 01 00:00:00 EST 1980

OSTI ID:5272177

Two fiber-composite flywheel rotors were fabricated. These flywheels are scaled-down versions of two automotive flywheels built for Sandia Laboratories. The design fabrication of the scaled-down versions was necessitated by the limitations imposed on the testing of the 5 kWh prototypes at the Oak Ridge Flywheel Evaluation Laboratory. The flywheels store a maximum of 0.97 kWh of kinetic energy. Energy density is 87 Wh/kg at the maximum operating speed of 56,000 rpm. The nominal flywheel dimensions are 35 cm diameter by 13 cm axial height. The weight of the flywheel rotor assembly is 11.16 kg.
