摘要
Blade tip clearance is a key parameter in the process of aeroengines design and test, which directly affects the efficiency and safety. Real-time online monitoring of blade tip clearance for aeroengines has become an essential item in the test program. With the development of new aeroengines, blade tip clearance measurement technologies become more mature and in-depth. This paper introduces the basic measurement principle of blade tip clearance, describes the typical structure and common measurement process of the system, and summarizes six key technologies of the online blade tip clearance measurement. Measurement methods including the discharge probe method, the optical fiber method, the capacitance method, the eddy current method and the microwave method are analyzed in details to introduce their working principles, characteristics, research progress and future research directions. Research results and the latest products of various measurement methods are compared and summarized. The development trend and prospect for blade tip clearance measurement are put forward. Key research directions of the blade tip clearance measurement are summarized from six aspects, which provide references for the follow-up research. © 2022 AAAS Press of Chinese Society of Aeronautics and Astronautics.
