The vibration faults of aeroengine highpressure compressor rotor blade were analyzed. The highintensity sound waves contained in the high-strength noise generated by the compressor in a non-normal working condition one of the reasons for rotor blade excitation resonance or flutter. By theoretical analysis and experimental verification, the following conclusions were obtained: If the high stress caused by mechanical excitation and aerodynamic excitation and the superposition of the resonance stress caused by sound waves together affect the rotor blade, it can produce cracks and damages.
