Coupling Flutter of Circular Cascading Blade Rows with Splitter Blades.
TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series B, 1995 Present paper aimed to analyze the coupled torsional and bending flluter of a compressor circular cascade composed of main and splitter blades. From the theoretical treatment of the analysis, the unsteady forces and moments of blades carried out a combined motion of torsion and bending are calculated for the main and splitter blades. Numerical examples

Flutter control of incompressible flow turbomachine blade rows by splitter blades
27th Joint Propulsion Conference, 1991 Splitter blades as a passive flutter control technique are investigated by developing a mathematical model to predict the stability of an aerodynamically loaded splittered-rotor operating in an incompressible flow field. The splitter blades, positioned circumferentially in the flow passage between two principal blades, introduce aerodynamic and/or ...
