Abstract:
An actively controlled squeeze film damper system comprises a housing defining an annulus receiving a damping fluid during operation, a lubricant source supplying damping fluid to the annulus, and a sensor assembly for measuring a parameter indicative of a compressibility of the damping fluid. A control device adjusts the compressibility of the damping fluid within a predefined range.
