摘要
Abstract
To solve the tip diameter measurement of existing assembly clearance,easy clashing appearance,difficulty in fixation of aero-engine high pressure turbine rotor (HPTR) blades,a new process method is proposed by taking the adjacent left and right blade tips as the support reaction force points which externally support the measuring blade to eliminate the radial clearance.External support measurement device for HPTR blades is designed,and on the condition of high pressure turbine without dividing the rear baffle,the rotor blades are externally supported and fixed.The tip diameter measurement experiment for HPTR Blades is carried out and the measurement system accuracy is analyzed,whose the accuracy is 0.04 mm to meet the present measurement reqirement,which will lay an important foundation for developing the high precision tip diameter measuement instruments for aero-engine HPTR blades.关键词
