Aerodynamic Factors of Influence on the Resonance Vibration of Gas Turbine Compressor Blades.

The paper presents results of an analysis of the gas-dynamic control of flow around the guide blades of axial compressor stage for the vibration intensity of rotor blades. It has been shown that gas-dynamic action on flow around blades equalizes the flow velocity field before the rotor and reduces the level of resonant stresses in blades in the case of their resonant excitation.
