Dual-clearance (two oil films) squeeze-film damper developed for controlling vibrations in aircraft turbine engines and other rotating machinery. New damper under normal conditions uses only one low-clearance film. Under high imbalance, both films active, controlling shaft vibration in nearoptimum manner and allowing continued operation until safe shutdown made.
