Abstract
This report contains a brief review of the unsteady aerodynamic and aeroelastic phenomena of relevance to the operation of the Inco fan installation. The review addresses issues associated with unsteady inlet flow phenomena due to an upstream vortical wake and the aeroelastic flutter characteristics of the rotor assembly. Based on the available information on inlet flow and blade structural dynamic characteristics a number of conclusions are made. Firstly the vortical wake will be three dimensional in nature, although the von Karman vortices generated from the motor housing will predominate. These have the potential to induce vibration in the fan blading, and should be investigated further. Secondly, it is recommended that the potential for stall flutter and single mode bending-torsion flutter be further investigated.
