The research of blade surface's on-line inspection's method

The blade is the key parts of aero-engine,to ensure the quality of blade surface is important to improve engine performance and efficiency.This paper presents on-line inspection of the blade surface to improve the inspection efficiency and precision.It summarizes the contact online inspection's principle、composition.One key technique of on-line inspection is the measure-point's disposal and layout.It brings forward a new method-UV intercept method,Examination and emulator suggest that this method which accord to the character of blade profile machining can improve the inspection efficiency and precision of the blade.
