The surface quality and profile accuracy of blade directly affect the aero-dynamic and working performance of aeroengine. The scientific inspection for aeroengine blade is the crucial technologies to ensure the manufacturing accuracy of blades. Aiming at the current situation of existing gap between China’s aero blade measurement technology with equipment and foreign advanced level

by summarizing the research status and development trend of coordinate measuring machine measurement technology for blade

it can provide a reference for the development of blade detection technology and related instrument. Firstly

the importance and necessity of blade inspection are expounded

and a series of technical difficulties in detecting process are introduced. Secondly

the technical status and equipment are analyzed

and the key technology and its research progress in the detection process are emphatically introduced. Finally

the development trend is pointed out based on the current research status.
