Abstract: This paper presents the aero-engine intelligent measurement system which has been developed.The system is original and new in its global design.It integrates the data acquisition,realtime calibration,displacement control,angle tracking,data processing and table printing.The sustem has been used successfully in combustion and turbine testings,its technical and economic effectiveness has been proved remarkable. It is of very great practical value not only in developing aero-engine and its parts,but also in its extension to other military and civil industrial departments.
