Abstract
In this paper a novel, high load squeeze film damper design, supporting analysis, and experimental results are presented. The spiral foil multi-squeeze film damper demonstrated that two to four fold or larger increases in damping levels are possible without resorting to significantly decreased damper clearances. As a result, the nonlinearities associated with high eccentricity operation are avoided. Controlled orbit tests with a dual squeeze film configuration were completed and favorably compared with theoretical predictions. The ability to accommodate high steady state and transient imbalance conditions make this damper well suited to a wide range of rotating machinery, including aircraft gas turbine engines.
