Analysis of Defect Detection Technology of Aero Engine High Pressure Turbine Blade
As a key component of aero engine,turbine blade has a complex processing process,which requires very high quality detection.High pressure turbine blades manufactured by laser direct writing(LDM)are char-acterized by high precision,high density and high spectral resolution,and can be used for 3D measurement,non-destructive testing and 3D reconstruction of 3D products.With the application of laser direct writing technology in domestic high pressure turbine blade manufacturers,high pressure turbine blades have achieved mass produc-tion.In this paper,the laser direct writing forming process and defect detection technology of domestic high pressure turbine blades are introduced,and the defect detection method and software are analyzed.
