Development of Dynamics models for Turbo machinery Squeeze Film Dampers

Vibration of aircraft engine is the major contribution to the structure vibration in an aircraft. To reduce the cabin noise and improve the comfortability for air passenger, research design and analysis are desired in the engine technology. A critical component in eliminating the vibration in an aero engine is the squeeze film damper (SFD). Current SFD models are oversimplified to describe the practical issues related to the phenomenon of air entrainment and turbulence flows. This project will collaborate with research resources from the University of Toronto and Pratt & Whitney Canada to develop dynamic models of SFD to address the above problem. The new technology will be applied in aircraft engine design to reduce the noise and vibration, aiming to keep the Canadian aerospace industry competitive in the global market.
