Abstract

Non-contact high-precision online measurement of blade tip clearance is the key to efficiency and safety of aeroengines. However, the traditional static measurement method based on microwave faces the problem of precision decline under the influence of direct current noise, distance measurement ambiguity, and variation of signal sampling time points. Therefore, a dynamic measurement method of blade tip clearance is proposed based on microwave phase difference ranging. A measurement signal model is established. The strength and phase signals of the blades with different thickness and cavity are simulated and analyzed. A new technical method combining techniques of phase region adaptive interception, scale adjustment, correlation matching, and polynomial fitting is proposed to realize high-precision dynamic measurement of blade tip clearance. The method can solve the ambiguity problem of microwave phase signal ranging, realize the estimation of the phase signal's peak position, and reduce random errors in the signal processing process. A prototype of blade tip clearance measurement is developed based on microwave phase difference ranging, and an experimental platform for dynamic measurement of the blade tip clearance signal is built in the laboratory to carry out measurement and calibration experiments. Experimental results verify the effectiveness and accuracy of the proposed method, which is applicable for measurement of blades of different thicknesses and H-form cavity. For the blade with different thickness and shape, the dynamic measurement accuracy of blade tip clearance is better than 40 μm over the range of 0.5 mm to 3 mm when the rotation speed of the blade is 3 000 r/min. For the blade with 2 mm thickness, the measurement accuracy is still better than 60 μm over the range of 0.5 mm to 3 mm when the speed is up to 24 000 r/min.
