Analysis of Radial Diffuser Blade Fracture in an Aircraft Engine
In order to determine the fracture nature and cause of the radial diffuser blade fracture fault in an aircraft engine,a preliminary failure analysis was conducted through the failure analysis of the radial diffuser blade,and detailed fault analysis was conducted from the aspects of material,design,processing,and environmental impact of the radial diffuser.The result indicates that the fracture property of the blade is high-cycle fatigue.In the working state of the aircraft engine,the radial diffuser exhibits resonance within the operating speed range,and the highsress zone is located at the root of the leading edge of the blade,resulting in cracks in the blade and ultimately leading to high-cycle fatigue.It is recommended to optimize the blade shape and avoid resonance to avoid similar faults from recurring.
