Abstract
An improved fluid film bearing having a squeeze film damper tailored to the dynamic vibration characteristics of a turbomachine. Compact cantilevered spring bars support the squeeze film damper and thin fluid film bearing surface against the rotor shaft. The spring bars fit compactly within the bearing. The squeeze film damper includes oil plenums that provide a reservoir of fluid and prevent air from entering the damper and thin fluid film.
