Validation and calibration of Squeeze Film Damper Model with Experiment
This research project studies a specific component in the commercial aircraft engine called the squeezed film damper, or SFD. The SFD is applied to reduce the vibration of the engine rotor, which in turn reduces the noise and brings comfort to the passengers. The expected delivery from this project includes an advanced SFD model which will be used by P&WC for the simulation of engine vibration. The developed model can also be studied as the guideline for an upgraded level of SFD design.
