摘要
Abstract
Efficiency drop and whistling phenomenon appear in a ground test of an aero-engine. Through the detailed analysis of the measured vibration and noise signals, the blade deformation of the first-stage axial-flow impeller of the engine is identified. Based on the detailed analysis of the fault, the characteristics of the noise spectrum due to the blade deformation are obtained. The results can provide a basis for blade deformation induced fault identification.关键词
