ABSTRACT:
Disclosed are methods and apparatus for providing torsional fluid dampening in the kHz region with an inertial mass located in a rotary fluid container, and with a viscous fluid friction boundary layer located between that mass and a circumferential wall of the container. A supply of viscous liquid having a volume equal to the combined volumes of the boundary layer and inertial mass is provided. Both the inertial mass and the boundary layer are formed with that supply of viscous liquid in the fluid container which may then be rotated.
