Abstract

A parametric study of the unstalled flutter stability character- istics of compressor and turbine cascades in subsonic and super- sonic flow is carried out. Based on typical section two- dimensional cascade models, stability boundaries and dominant trends in flutter behaviour are outlined with emphasis on the effects of a) single mode structural coupling in bending and torsion, b) coupling among multiple blade degrees of freedom, c) mass ratio and structural damping, d) compressibility, e) cascade solidity and stagger, f) steady aerodynamic blade loading. Practical design aspects are in the foreground of all of these investigations.
