Abstract
Physical mechanisms are discussed which lead to the aeromechanical response of axial-flow fan and compressor components when these machines operate with a distorted inlet flow. Steady response of blades, vanes, and disks are considered briefly. Forced excitation of rotating components is treated in some detail. The specific form of the exciting gusts is elucidated. Self-excited vibrations of rotor blades and stator vanes are considered as stemming from the general degradation of flow with distortion. Shaft and disk vibrations are also discussed as possible aeromechanical responses to distorted flow. The role of various forms of damping and the use of composite materials is described.
