Fail-safe rotary machine

摘要: This invention relates to a fail-safe rotating machine wherein pre-determined failure locations are designed into the element assure minimum energy release upon of due centrifugal forces acting thereon. In specific illustrated embodiment, cylindrical flywheel mounted motor shaft is formed juxtaposed discs having diverse tensile strengths inhibit simultaneous discs. Also disclosed techniques for assuring by fabricating concentric rings differing thicknesses or notching surface unitary in design producing segments desired configuration failure.
