Research on the Accumulative Damage of Flywheels Due to In-Space Charging Effects
AerospaceHigh-speed rotating flywheel bearings, designed for space applications, generate a high-resistance hydrodynamic lubrication film, which isolates the rotor, transforming it into a conductor. This phenomenon introduces a novel failure mode—flywheel bearing
